(6.1) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries, Inc. 1-800-818-4555 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. More than 1100 patients with stage II or III colon cancer and more than 4,000 patients with advanced colorectal cancer have been treated in clinical studies with oxaliplatin injection. The most common adverse reactions in patients with stage II or III colon cancer receiving adjuvant therapy were peripheral sensory neuropathy, neutropenia, thrombocytopenia, anemia, nausea, increase in transaminases and alkaline phosphatase, diarrhea, emesis, fatigue and stomatitis. The most common adverse reactions in previously untreated and treated patients were peripheral sensory neuropathies, fatigue, neutropenia, nausea, emesis, and diarrhea [see Warnings and Precautions (5)]. Combination Adjuvant Therapy with Oxaliplatin Injection and Infusional 5-fluorouracil/leucovorin in Patients with Colon Cancer One thousand one hundred and eight patients with stage II or III colon cancer, who had undergone complete resection of the primary tumor, have been treated in clinical study with oxaliplatin injection in combination with infusional 5-fluorouracil/leucovorin [see Clinical Studies (14)]. The incidence of grade or adverse reactions was 70% on the oxaliplatin injection combination arm, and 31% on the infusional 5-fluorouracil/leucovorin arm. The adverse reactions in this trial are shown in the tables below. Discontinuation of treatment due to adverse reactions occurred in 15% of the patients receiving oxaliplatin injection and infusional 5-fluorouracil/leucovorin. Both 5-fluorouracil/leucovorin and oxaliplatin injection are associated with gastrointestinal or hematologic adverse reactions. When oxaliplatin injection is administered in combination with infusional 5-fluorouracil/leucovorin, the incidence of these events is increased. The incidence of death within 28 days of last treatment, regardless of causality, was 0.5% (n=6) in both the oxaliplatin injection combination and infusional 5-fluorouracil/leucovorin arms, respectively. Deaths within 60 days from initiation of therapy were 0.3% (n=3) in both the oxaliplatin injection combination and infusional 5-fluorouracil/leucovorin arms, respectively. On the oxaliplatin injection combination arm, deaths were due to sepsis/neutropenic sepsis, from intracerebral bleeding and one from eosinophilic pneumonia. On the 5-fluorouracil/leucovorin arm, one death was due to suicide, from Steven-Johnson Syndrome (1 patient also had sepsis), unknown cause, anoxic cerebral infarction and probable abdominal aorta rupture. The following table provides adverse reactions reported in the adjuvant therapy colon cancer clinical trial [see Clinical Studies (14)] by body system and decreasing order of frequency in the oxaliplatin injection and infusional 5-fluorouracil/leucovorin arm for events with overall incidences >= 5% and for NCI grade 3/4 events with incidences >= 1%.Table - Adverse Reactions Reported in Patients with Colon Cancer receiving Adjuvant Treatment (>=5% of all patients and with >=1% NCI Grade 3/4 events) Oxaliplatin Injection 5-FU/LV N=11085-FU/LV N=1111Adverse reaction (WHO/Pref) All Grades(%)Grade 3/4(%)All Grades(%)Grade 3/4(%)Any Event 100 70 99 31 Allergy/ImmunologyAllergic Reaction 10 2 <1 Constitutional Symptoms/PainFatigue 44 38 Abdominal Pain 18 17 Dermatology/SkinSkin Disorder 32 36 Injection Site ReactionIncludes thrombosis related to the catheter 11 10 GastrointestinalNausea 74 61 Diarrhea 56 11 48 Vomiting 47 24 Stomatitis 42 40 Anorexia 13 8 <1 Fever/InfectionFever 27 12 Infection 25 25 NeurologyOverall Peripheral Sensory Neuropathy 92 12 16 <1 The following table provides adverse reactions reported in the adjuvant therapy colon cancer clinical trial [see Clinical Studies (14)] by body system and decreasing order of frequency in the oxaliplatin injection and infusional 5-fluorouracil/leucovorin arm for events with overall incidences >= 5% but with incidences <1% NCI grade 3/4 events.

However, the following grade 3/4 events were more common in females: diarrhea, fatigue, granulocytopenia, nausea and vomiting. In patients >=65 years old, the incidence of grade 3/4 diarrhea and granulocytopenia was higher than in younger patients. Insufficient subgroup sizes prevented analysis of safety by race. The following additional adverse reactions, were reported in >=2% and <5% of the patients in the oxaliplatin injection and infusional 5-fluorouracil/leucovorin combination arm (listed in decreasing order of frequency): pain, leukopenia, weight decrease, coughing. The number of patients who developed secondary malignancies was similar; 62 in the oxaliplatin injection combination arm and 68 in the infusional 5-fluorouracil/leucovorin arm. An exploratory analysis showed that the number of deaths due to secondary malignancies was 1.96% in the oxaliplatin injection combination arm and 0.98% in infusional 5-fluorouracil/leucovorin arm. In addition, the number of cardiovascular deaths was 1.4% in the oxaliplatin injection combination arm as compared to 0.7% in the infusional 5-fluorouracil/leucovorin arm. Clinical significance of these findings is unknown. Patients Previously Untreated for Advanced Colorectal Cancer Two hundred and fifty-nine patients were treated in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm of the randomized trial in patients previously untreated for advanced colorectal cancer [see Clinical Studies (14)]. The adverse reaction profile in this study was similar to that seen in other studies and the adverse reactions in this trial are shown in the tables below. Both 5-fluorouracil and oxaliplatin injection are associated with gastrointestinal and hematologic adverse reactions. When oxaliplatin injection is administered in combination with 5-fluorouracil, the incidence of these events is increased. The incidence of death within 30 days of treatment in the previously untreated for advanced colorectal cancer study, regardless of causality, was 3% with the oxaliplatin injection and 5-fluorouracil/leucovorin combination, 5% with irinotecan plus 5-fluorouracil/leucovorin, and 3% with oxaliplatin injection plus irinotecan. Deaths within 60 days from initiation of therapy were 2.3% with the oxaliplatin injection and 5-fluorouracil/leucovorin combination, 5.1% with irinotecan plus 5-fluorouracil/leucovorin, and 3.1% with oxaliplatin injection plus irinotecan. The following table provides adverse reactions reported in the previously untreated for advanced colorectal cancer study [see Clinical Studies (14)] by body system and decreasing order of frequency in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm for events with overall incidences >=5% and for grade 3/4 events with incidences >=1%.Table - Adverse Reactions Reported in Patients Previously Untreated for Advanced Colorectal Cancer Clinical Trial (>=5% of all patients and with >=1% NCI Grade 3/4 events) Oxaliplatin Injection 5-FU/LV N=259Irinotecan 5-FU/LV N=256Oxaliplatin Injection Irinotecan N=258Adverse reaction (WHO/Pref)All Grades (%)Grade 3/4 (%)All Grades (%)Grade 3/4 (%)All Grades (%)Grade 3/4(%)Any Event 99 82 98 70 99 76 Allergy/ImmunologyHypersensitivity 12 5 6 CardiovascularThrombosis 5 6 3 Hypotension 3 3 3 Constitutional Symptoms/Pain/Ocular/VisualFatigue 70 58 11 66 16 Abdominal Pain 29 31 39 10 Myalgia 14 6 9 Pain 1 1 1 Vision abnormal 0 1 1 Neuralgia 0 0 1 Dermatology/SkinSkin reaction hand/foot 1 1 0 Injection site reaction 0 0 1 GastrointestinalNausea 71 67 15 83 19 Diarrhea 56 12 65 29 76 25 Vomiting 41 43 13 64 23 Stomatitis 38 25 19 Anorexia 35 25 27 Constipation 32 27 21 Diarrhea-colostomy 13 16 16 Gastrointestinal NOSNot otherwise specified 2 2 2 Hematology/InfectionInfection normal ANCAbsolute neutrophil count 10 5 7 Infection low ANC 8 12 11 8 Lymphopenia 2 1 2 Febrile neutropenia 4 15 14 12 11 Hepatic/Metabolic/Laboratory/RenalHyperglycemia 14 11 12 Hypokalemia 11 7 6 Dehydration 5 16 11 14 Hypoalbuminemia 0 2 1 Hyponatremia 2 4 1 Urinary frequency 1 1 1 NeurologyOverall Neuropathy 82 19 18 69 Paresthesias 77 18 16 62 Pharyngo-laryngeal dysesthesias 38 1 28 Neuro-sensory 12 2 9 Neuro NOS 0 0 0 PulmonaryCough 35 25 17 Dyspnea 18 14 11 Hiccups 1 0 2 The following table provides adverse reactions reported in the previously untreated for advanced colorectal cancer study [see Clinical Studies (14)] by body system and decreasing order of frequency in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm for events with overall incidences >=5% but with incidences <1% NCI Grade 3/4 events.

The following additional adverse reactions, at least possibly related to treatment and potentially important, were reported in >=2% and <5% of the patients in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm (listed in decreasing order of frequency): metabolic, pneumonitis, catheter infection, vertigo, prothrombin time, pulmonary, rectal bleeding, dysuria, nail changes, chest pain, rectal pain, syncope, hypertension, hypoxia, unknown infection, bone pain, pigmentation changes, and urticaria. Previously Treated Patients with Advanced Colorectal Cancer Four hundred and fifty patients (about 150 receiving the combination of oxaliplatin injection and 5-fluorouracil/leucovorin) were studied in randomized trial in patients with refractory and relapsed colorectal cancer [see Clinical Studies (14)]. The adverse reaction profile in this study was similar to that seen in other studies and the adverse reactions in this trial are shown in the tables below. Thirteen percent of patients in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm and 18% in the 5-fluorouracil/leucovorin arm of the previously treated study had to discontinue treatment because of adverse effects related to gastrointestinal, or hematologic adverse reactions, or neuropathies. Both 5-fluorouracil and oxaliplatin injection are associated with gastrointestinal and hematologic adverse reactions. When oxaliplatin injection is administered in combination with 5-fluorouracil, the incidence of these events is increased. The incidence of death within 30 days of treatment in the previously treated study, regardless of causality, was 5% with the oxaliplatin injection and 5-fluorouracil/leucovorin combination, 8% with oxaliplatin injection alone, and 7% with 5-fluorouracil/leucovorin. Of the deaths that occurred on the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm within 30 days of stopping treatment, may have been treatment related, associated with gastrointestinal bleeding or dehydration. The following table provides adverse reactions reported in the previously treated study [see Clinical Studies (14)] by body system and in decreasing order of frequency in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm for events with overall incidences >=5% and for grade 3/4 events with incidences >=1%.

The incidence of all hemorrhagic events in the adjuvant and previously treated patients was higher on the oxaliplatin injection combination arm compared to the infusional 5-fluorouracil/leucovorin arm. These events included gastrointestinal bleeding, hematuria, and epistaxis. In the adjuvant trial, two patients died from intracerebral hemorrhages.The incidence of Grade 3/4 thrombocytopenia was 2% in adjuvant patients with colon cancer. In patients treated for advanced colorectal cancer the incidence of Grade 3/4 thrombocytopenia was to 5%, and the incidence of these events was greater for the combination of oxaliplatin injection and 5-fluorouracil/leucovorin over the irinotecan plus 5-fluorouracil/leucovorin or 5-fluorouracil/leucovorin control groups. Grade 3/4 gastrointestinal bleeding was reported in 0.2% of adjuvant patients receiving oxaliplatin injection and 5-fluorouracil/leucovorin. In the previously untreated patients, the incidence of epistaxis was 10% in the oxaliplatin injection and 5-fluorouracil/leucovorin arm, and 2% and 1%, respectively, in the irinotecan plus 5-fluorouracil/leucovorin or irinotecan plus oxaliplatin injection arms.NeutropeniaNeutropenia was frequently observed with the combination of oxaliplatin injection and 5-fluorouracil/leucovorin, with Grade and events reported in 29% and 12% of adjuvant patients with colon cancer, respectively. In the adjuvant trial, patients died from sepsis/neutropenic sepsis. Grade and events were reported in 35% and 18% of the patients previously untreated for advanced colorectal cancer, respectively. Grade and events were reported in 27% and 17% of previously treated patients, respectively. In adjuvant patients the incidence of either febrile neutropenia (0.7%) or documented infection with concomitant grade 3/4 neutropenia (1.1%) was 1.8% in the oxaliplatin injection and 5-fluorouracil/leucovorin arm. The incidence of febrile neutropenia in the patients previously untreated for advanced colorectal cancer was 15% (3% of cycles) in the irinotecan plus 5-fluorouracil/leucovorin arm and 4% (less than 1% of cycles) in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm. Additionally, in this same population, infection with grade or neutropenia was 12% in the irinotecan plus 5-fluorouracil/leucovorin, and 8% in the oxaliplatin injection and 5-fluorouracil/leucovorin combination. The incidence of febrile neutropenia in the previously treated patients was 1% in the 5-fluorouracil/leucovorin arm and 6% (less than 1% of cycles) in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm.GastrointestinalIn patients receiving the combination of oxaliplatin injection plus infusional 5-fluorouracil/leucovorin for adjuvant treatment for colon cancer the incidence of Grade 3/4 nausea and vomiting was greater than those receiving infusional 5-fluorouracil/leucovorin alone (see table). In patients previously untreated for advanced colorectal cancer receiving the combination of oxaliplatin injection and 5-fluorouracil/leucovorin, the incidence of Grade and vomiting and diarrhea was less compared to irinotecan plus 5-fluorouracil/leucovorin controls (see table). In previously treated patients receiving the combination of oxaliplatin injection and 5-fluorouracil/leucovorin, the incidence of Grade and nausea, vomiting, diarrhea, and mucositis/stomatitis increased compared to 5-fluorouracil/leucovorin controls (see table).The incidence of gastrointestinal adverse reactions in the previously untreated and previously treated patients appears to be similar across cycles. Premedication with antiemetics, including 5-HT3 blockers, is recommended. Diarrhea and mucositis may be exacerbated by the addition of oxaliplatin injection to 5-fluorouracil/leucovorin, and should be managed with appropriate supportive care. Since cold temperature can exacerbate acute neurological symptoms, ice (mucositis prophylaxis) should be avoided during the infusion of oxaliplatin injection.DermatologicOxaliplatin injection did not increase the incidence of alopecia compared to 5-fluorouracil/leucovorin alone. No complete alopecia was reported. The incidence of Grade 3/4 skin disorders was 2% in both the oxaliplatin injection plus infusional 5-fluorouracil/leucovorin and the infusional 5-fluorouracil/leucovorin alone arms in the adjuvant colon cancer patients. The incidence of hand-foot syndrome in patients previously untreated for advanced colorectal cancer was 2% in the irinotecan plus 5-fluorouracil/leucovorin arm and 7% in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm. The incidence of hand-foot syndrome in previously treated patients was 13% in the 5-fluorouracil/leucovorin arm and 11% in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm.Intravenous Site ReactionsExtravasation, in some cases including necrosis, has been reported. Injection site reaction, including redness, swelling, and pain, has been reported.Anticoagulation and HemorrhageThere have been reports while on study and from postmarketing surveillance of prolonged prothrombin time and INR occasionally associated with hemorrhage in patients who received oxaliplatin injection plus 5-fluorouracil/leucovorin while on anticoagulants. Patients receiving oxaliplatin injection plus 5-fluorouracil/leucovorin and requiring oral anticoagulants may require closer monitoring.RenalAbout to 10% of patients in all groups had some degree of elevation of serum creatinine. The incidence of Grade 3/4 elevations in serum creatinine in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm was 1% in the previously treated patients. Serum creatinine measurements were not reported in the adjuvant trial.Hepatic Hepatotoxicity (defined as elevation of liver enzymes) appears to be related to oxaliplatin injection combination therapy [see Warnings and Precautions (5.5)]. The following tables list the clinical chemistry changes associated with hepatic toxicity occurring in >=5% of patients, based on adverse reactions reported and NCI CTC grade for adjuvant patients and patients previously untreated for advanced colorectal cancer, laboratory values and NCI CTC grade for previously treated patients.

The incidence was and 9% of the patients previously untreated for advanced colorectal cancer and previously treated patients in the oxaliplatin injection and 5-fluorouracil/leucovorin combination arm, respectively.. 6.2 Postmarketing Experience. The following adverse reactions have been identified during post-approval use of oxaliplatin injection. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Body as whole:angioedema, anaphylactic shockCardiovascular disorders:QT prolongation leading to ventricular arrhythmias including fatal Torsade de Pointes Central and peripheral nervous system disorders:loss of deep tendon reflexes, dysarthria, Lhermittes sign, cranial nerve palsies, fasciculations, convulsion, Reversible Posterior Leukoencephalopathy Syndrome (RPLS, also known as PRES).Hearing and vestibular system disorders:deafnessInfections:septic shock, including fatal outcomesInfusion reactions/hypersensitivity: laryngospasmLiver and Gastrointestinal system disorders:severe diarrhea/vomiting resulting in hypokalemia, colitis (including Clostridium difficile diarrhea), metabolic acidosis; ileus; intestinal obstruction, pancreatitis; veno-occlusive disease of liver also known as sinusoidal obstruction syndrome, and perisinusoidal fibrosis which rarely may progress.Musculoskeletal and connective tissue disordersrhabdomyolysis, including fatal outcomes. Platelet, bleeding, and clotting disorders:immuno-allergic thrombocytopeniaprolongation of prothrombin time and of INR in patients receiving anticoagulantsRed Blood Cell disorders:hemolytic uremic syndrome, immuno-allergic hemolytic anemiaRenal disorders:Acute tubular necrosis, acute interstitial nephritis and acute renal failure.Respiratory system disorders:pulmonary fibrosis, and other interstitial lung diseases (sometimes fatal) Vision disorders:decrease of visual acuity, visual field disturbance, optic neuritis and transient vision loss (reversible following therapy discontinuation).

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term animal studies have not been performed to evaluate the carcinogenic potential of oxaliplatin. Oxaliplatin was not mutagenic to bacteria (Ames test) but was mutagenic to mammalian cells in vitro (L5178Y mouse lymphoma assay). Oxaliplatin was clastogenic both in vitro (chromosome aberration in human lymphocytes) and in vivo (mouse bone marrow micronucleus assay). In fertility study, male rats were given oxaliplatin at 0, 0.5, 1, or mg/kg/day for five days every 21 days for total of three cycles prior to mating with females that received two cycles of oxaliplatin on the same schedule. dose of mg/kg/day (less than one-seventh the recommended human dose on body surface area basis) did not affect pregnancy rate, but caused developmental mortality (increased early resorptions, decreased live fetuses, decreased live births) and delayed growth (decreased fetal weight). Testicular damage, characterized by degeneration, hypoplasia, and atrophy, was observed in dogs administered oxaliplatin at 0.75 mg/kg/day 5 days every 28 days for three cycles. no effect level was not identified. This daily dose is approximately one-sixth of the recommended human dose on body surface area basis.

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Oxaliplatin undergoes nonenzymatic conversion in physiologic solutions to active derivatives via displacement of the labile oxalate ligand. Several transient reactive species are formed, including monoaquo and diaquo DACH platinum, which covalently bind with macromolecules. Both inter- and intrastrand Pt-DNA crosslinks are formed. Crosslinks are formed between the N7 positions of two adjacent guanines (GG), adjacent adenine-guanines (AG), and guanines separated by an intervening nucleotide (GNG). These crosslinks inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific. In vivo studies have shown antitumor activity of oxaliplatin against colon carcinoma. In combination with 5-fluorouracil, oxaliplatin exhibits in vitro and in vivo antiproliferative activity greater than either compound alone in several tumor models [HT29 (colon), GR (mammary), and L1210 (leukemia)].. 12.3 Pharmacokinetics. The reactive oxaliplatin derivatives are present as fraction of the unbound platinum in plasma ultrafiltrate. The decline of ultrafilterable platinum levels following oxaliplatin administration is triphasic, characterized by two relatively short distribution phases (t1/2; 0.43 hours and t1/2; 16.8 hours) and long terminal elimination phase (t1/2; 391 hours). Pharmacokinetic parameters obtained after single 2-hour intravenous infusion of oxaliplatin injection at dose of 85 mg/m2 expressed as ultrafilterable platinum were Cmax of 0.814 mcg/mL and volume of distribution of 440 L. Interpatient and intrapatient variability in ultrafilterable platinum exposure (AUC0-48hr) assessed over cycles was moderate to low (23% and 6%, respectively). pharmacodynamic relationship between platinum ultrafiltrate levels and clinical safety and effectiveness has not been established. Distribution At the end of 2-hour infusion of oxaliplatin injection, approximately 15% of the administered platinum is present in the systemic circulation. The remaining 85% is rapidly distributed into tissues or eliminated in the urine. In patients, plasma protein binding of platinum is irreversible and is greater than 90%. The main binding proteins are albumin and gamma-globulins. Platinum also binds irreversibly and accumulates (approximately 2-fold) in erythrocytes, where it appears to have no relevant activity. No platinum accumulation was observed in plasma ultrafiltrate following 85 mg/m2 every two weeks. Metabolism Oxaliplatin undergoes rapid and extensive nonenzymatic biotransformation. There is no evidence of cytochrome P450-mediated metabolism in vitro. Up to 17 platinum-containing derivatives have been observed in plasma ultrafiltrate samples from patients, including several cytotoxic species (monochloro DACH platinum, dichloro DACH platinum, and monoaquo and diaquo DACH platinum) and number of noncytotoxic, conjugated species. Elimination The major route of platinum elimination is renal excretion. At five days after single 2-hour infusion of oxaliplatin injection, urinary elimination accounted for about 54% of the platinum eliminated, with fecal excretion accounting for only about 2%. Platinum was cleared from plasma at rate (10 to 17 L/h) that was similar to or exceeded the average human glomerular filtration rate (GFR; 7.5 L/h). There was no significant effect of gender on the clearance of ultrafilterable platinum. The renal clearance of ultrafilterable platinum is significantly correlated with GFR. Pharmacokinetics in Special Populations Pediatric [See Use In Specific Patient Populations (8.4)]. Renal Impairment study was conducted in 38 patients with advanced GI cancer and varying degrees of renal impairment. Patients in the normal (creatinine clearance (CrCL) 80 mL/min, = 11), mild (CrCL 50 to 80 mL/min, = 13), and moderate (CrCL 30 to 49 mL/min, = 10) groups were treated with 85 mg/m2 oxaliplatin injection and those in the severe (CrCL 30 mL/min, = 4) group were treated with 65 mg/m2 oxaliplatin injection. The mean AUC of unbound platinum was 40%, 95%, and 342% higher in the mild, moderate, and severe groups, respectively, than in the normal group. Mean Cmax of unbound platinum appeared to be similar among the normal, mild and moderate renal function groups, but was 38% higher in the severe group than in the normal group. Caution should be exercised in renally impaired patients [see Use in Specific Populations (8.6)]. The starting dose of oxaliplatin injection should be reduced in patients with severe renal impairment [see Dosage and Administration (2.2)]. Drug Drug Interactions No pharmacokinetic interaction between 85 mg/m2 of oxaliplatin injection and infusional 5-fluorouracil has been observed in patients treated every weeks, but increases of 5-fluorouracil plasma concentrations by approximately 20% have been observed with doses of 130 mg/m2 of oxaliplatin injection administered every weeks. In vitro, platinum was not displaced from plasma proteins by the following medications: erythromycin, salicylate, sodium valproate, granisetron, and paclitaxel. In vitro, oxaliplatin is not metabolized by, nor does it inhibit, human cytochrome P450 isoenzymes. No P450-mediated drug-drug interactions are therefore anticipated in patients. Since platinum-containing species are eliminated primarily through the kidney, clearance of these products may be decreased by coadministration of potentially nephrotoxic compounds, although this has not been specifically studied.

14 CLINICAL STUDIES. 14.1 Combination Adjuvant Therapy with Oxaliplatin Injection and Infusional 5-fluorouracil/leucovorin in Patients withColon Cancer. An international, multicenter, randomized study compared the efficacy and evaluated the safety of oxaliplatin injection in combination with an infusional schedule of 5-fluorouracil/leucovorin to infusional 5-fluorouracil/leucovorin alone, in patients with stage II (Dukes B2) or III (Dukes C) colon cancer who had undergone complete resection of the primary tumor. The primary objective of the study was to compare the 3-year disease-free survival (DFS) in patients receiving oxaliplatin injection and infusional 5-fluorouracil/leucovorin to those receiving 5-fluorouracil/leucovorin alone. Patients were to be treated for total of months (i.e., 12 cycles). total of 2246 patients were randomized; 1123 patients per study arm. Patients in the study had to be between 18 and 75 years of age, have histologically proven stage II (T3-T4 N0 M0; Dukes B2) or III (any N1-2 M0; Dukes C) colon carcinoma (with the inferior pole of the tumor above the peritoneal reflection, i.e., >=15 cm from the anal margin) and undergone (within weeks prior to randomization) complete resection of the primary tumor without gross or microscopic evidence of residual disease. Patients had to have had no prior chemotherapy, immunotherapy or radiotherapy, and have an ECOG performance status of 0,1, or (KPS >= 60%), absolute neutrophil count (ANC) 1.5x109/L, platelets >=100x109/L, serum creatinine <= 1.25 ULN total bilirubin 2 ULN, AST/ALT 2 ULN and carcino-embryogenic antigen (CEA) 10 ng/mL. Patients with preexisting peripheral neuropathy (NCI grade >= 1) were ineligible for this trial.

North American, multicenter, open-label, randomized controlled study was sponsored by the National Cancer Institute (NCI) as an intergroup study led by the North Central Cancer Treatment Group (NCCTG). The study had arms at different times during its conduct, four of which were closed due to either changes in the standard of care, toxicity, or simplification. During the study, the control arm was changed to irinotecan plus 5-fluorouracil/leucovorin. The results reported below compared the efficacy and safety of two experimental regimens, oxaliplatin injection in combination with infusional 5-fluorouracil/leucovorinand combination of oxaliplatin injection plus irinotecan, to an approved control regimen of irinotecan plus 5-fluorouracil/leucovorinin 795 concurrently randomized patients previously untreated for locally advanced or metastatic colorectal cancer. After completion of enrollment, the dose of irinotecan plus 5-fluorouracil/leucovorinwas decreased due to toxicity. Patients had to be at least 18 years of age, have known locally advanced, locally recurrent, or metastatic colorectal adenocarcinoma not curable by surgery or amenable to radiation therapy with curative intent, histologically proven colorectal adenocarcinoma, measurable or evaluable disease, with an ECOG performance status 0, 1, or 2. Patients had to have granulocyte count >= 1.5 109/L, platelets >= 100 109/L, hemoglobin >=9 gm/dL, creatinine <= 1.5 ULN, total bilirubin <= 1.5 mg/dL, AST <= x ULN, and alkaline phosphatase <= x ULN. Patients may have received adjuvant therapy for resected Stage II or III disease without recurrence within 12 months. The patients were stratified for ECOG performance status (0, vs. 2), prior adjuvant chemotherapy (yes vs. no), prior immunotherapy (yes vs. no), and age (<65 vs. >=65 years). Although no post study treatment was specified in the protocol, 65 to 72% of patients received additional post study chemotherapy after study treatment discontinuation on all arms. Fifty-eight percent of patients on the oxaliplatin injection plus 5-fluorouracil/leucovorinarm received an irinotecan-containing regimen and 23% of patients on the irinotecan plus 5-fluorouracil/leucovorinarm received oxaliplatin-containing regimens. Oxaliplatin was not commercially available during the trial. The following table presents the dosing regimens of the three arms of the study.

The median number of cycles administered per patient was 10 (23.9 weeks) for the oxaliplatin injection and 5-fluorouracil/leucovorinregimen, (23.6 weeks) for the irinotecan plus 5-fluorouracil/leucovorinregimen, and (21 weeks) for the oxaliplatin injection plus irinotecan regimen. Patients treated with the oxaliplatin injection and 5-fluorouracil/leucovorincombination had significantly longer time to tumor progression based on investigator assessment, longer overall survival, and significantly higher confirmed response rate based on investigator assessment compared to patients given irinotecan plus 5-fluorouracil/leucovorin.

The study was intended to be analyzed for response rate after 450 patients were enrolled. Survival will be subsequently assessed in all patients enrolled in the completed study. Accrual to this study is complete, with 821 patients enrolled. Patients in the study had to be at least 18 years of age, have unresectable, measurable, histologically proven colorectal adenocarcinoma, with Karnofsky performance status >50%. Patients had to have SGOT(AST) and SGPT(ALT) <=2x the institutions upper limit of normal (ULN), unless liver metastases were present and documented at baseline by CT or MRI scan, in which case <=5x ULN was permitted. Patients had to have alkaline phosphatase <=2x the institutions ULN, unless liver metastases were present and documented at baseline by CT or MRI scan, in which cases <=5x ULN was permitted. Prior radiotherapy was permitted if it had been completed at least weeks before randomization. The dosing regimens of the three arms of the study are presented in the table below.Table 23 Dosing Regimens in Refractory and Relapsed Colorectal Cancer Clinical Trial Treatment ArmDoseRegimenOxaliplatin Injection 5-FU/LV(N =152) Day 1: Oxaliplatin Injection: 85 mg/m2 (2-hour infusion) LV 200 mg/m2 (2-hour infusion), followed by 5-FU: 400 mg/m2 (bolus), 600 mg/m2 (22-hour infusion)Day 2: LV 200 mg/m2 (2-hour infusion), followed by 5-FU: 400 mg/m2 (bolus), 600 mg/m2 (22-hour infusion) every weeks 5-FU/LV (N=151) Day 1: LV 200 mg/m2 (2-hour infusion), followed by 5-FU: 400 mg/m2 (bolus), 600 mg/m2 (22-hour infusion)Day 2: LV 200 mg/m2 (2-hour infusion), followed by 5-FU: 400 mg/m2 (bolus), 600 mg/m2 (22-hour infusion) every weeks Oxaliplatin Injection (N=156) Day 1: Oxaliplatin Injection 85 mg/m2 (2-hour infusion) every weeks Patients entered into the study for evaluation of response must have had at least one unidimensional lesion measuring >=20mm using conventional CT or MRI scans, or >=10mm using spiral CT scan. Tumor response and progression were assessed every cycles (6 weeks) using the Response Evaluation Criteria in Solid Tumors (RECIST) until radiological documentation of progression or for 13 months following the first dose of study drug(s), whichever came first. Confirmed responses were based on two tumor assessments separated by at least weeks.

Of the 13 patients who had tumor response to the combination of oxaliplatin injection and 5-fluorouracil/leucovorin, were female and were male, and responders included patients <65 years old and >=65 years old. The small number of non-Caucasian participants made efficacy analyses in these populations uninterpretable.

Figure The administration of oxaliplatin injection does not require prehydration. Premedication with antiemetics, including 5-HT3 blockers with or without dexamethasone, is recommended. For information on 5-fluorouracil and leucovorin, see the respective package inserts.. oxaliplatin-fig-1. 2.2 Dose Modification Recommendations. Prior to subsequent therapy cycles, patients should be evaluated for clinical toxicities and recommended laboratory tests [see Warnings and Precautions (5.11)]. Prolongation of infusion time for oxaliplatin injection from hours to hours may mitigate acute toxicities. The infusion times for 5-fluorouracil and leucovorin do not need to be changed. Adjuvant Therapy in Patients with Stage III Colon Cancer Neuropathy and other toxicities were graded using the NCI CTC scale version [see Warnings and Precautions (5.2)]. For patients who experience persistent Grade neurosensory events that do not resolve, dose reduction of oxaliplatin injection to 75 mg/m2 should be considered. For patients with persistent Grade neurosensory events, discontinuing therapy should be considered. The infusional 5-fluorouracil/leucovorin regimen need not be altered. dose reduction of oxaliplatin injection to 75 mg/m2 and infusional 5-fluorouracil to 300 mg/m2 bolus and 500 mg/m2 22 hour infusion is recommended for patients after recovery from grade 3/4 gastrointestinal (despite prophylactic treatment)or grade neutropenia, or febrile neutropenia, or grade 3/4 thrombocytopenia. The next dose should be delayed until: neutrophils >=1.5 109/L and platelets >=75 109/L. Dose Modifications in Therapy in Previously Untreated and Previously Treated Patients with Advanced Colorectal Cancer Neuropathy was graded using study-specific neurotoxicity scale [see Warnings and Precautions (5.2)]. Other toxicities were graded by the NCI CTC, Version 2. For patients who experience persistent Grade neurosensory events that do not resolve, dose reduction of oxaliplatin injection to 65 mg/m2 should be considered. For patients with persistent Grade neurosensory events, discontinuing therapy should be considered. The 5-fluorouracil/leucovorin regimen need not be altered. dose reduction of oxaliplatin injection to 65 mg/m2 and 5-fluorouracil by 20% (300 mg/m2 bolus and 500 mg/m2 22-hour infusion) is recommended for patients after recovery from grade 3/4 gastrointestinal (despite prophylactic treatment) or grade neutropenia, or febrile neutropenia, or grade 3/4 thrombocytopenia. The next dose should be delayed until: neutrophils >=1.5 109/L and platelets >=75 109/L. Dose Modifications in Therapy for Patients with Renal Impairment In patients with normal renal function or mild to moderate renal impairment, the recommended dose of oxaliplatin injection is 85 mg/m2. In patients with severe renal impairment, the initial recommended oxaliplatin injection dose should be reduced to 65 mg/m2 [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)].. 2.3 Preparation of Infusion Solution. Do not freeze and protect from light the concentrated solution.A final dilution must never be performed with sodium chloride solution or other chloride-containing solutions. The solution must be further diluted in an infusion solution of 250 to 500 mL of 5% Dextrose Injection, USP. After dilution with 250 to 500 mL of 5% Dextrose Injection, USP, the shelf life is hours at room temperature [20 to 25C (68 to 77F)] or up to 24 hours under refrigeration [2 to 8C (36 to 46F)]. After final dilution, protection from light is not required. Oxaliplatin injection is incompatible in solution with alkaline medications or media (such as basic solutions of 5-fluorouracil) and must not be mixed with these or administered simultaneously through the same infusion line. The infusion line should be flushed with 5% Dextrose Injection, USP prior to administration of any concomitant medication. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration and discarded if present. Needles or intravenous administration sets containing aluminum parts that may come in contact with oxaliplatin injection should not be used for the preparation or mixing of the drug. Aluminum has been reported to cause degradation of platinum compounds.

DOSAGE FORMS & STRENGTHS SECTION.


3 DOSAGE FORMS AND STRENGTHS. Oxaliplatin injection is supplied in single-use vials containing 50 mg or 100 mg of oxaliplatin, USP as sterile, preservative-free, aqueous solution at concentration of mg/mL.. Single-use vials of 50 mg or 100 mg oxaliplatin as sterile, preservative-free, aqueous solution at concentration of mg/mL. (3).

DRUG INTERACTIONS SECTION.


7 DRUG INTERACTIONS. No specific cytochrome P-450-based drug interaction studies have been conducted. No pharmacokinetic interaction between 85 mg/m2 oxaliplatin injection and 5-fluorouracil/leucovorin has been observed in patients treated every weeks. Increases of 5-fluorouracil plasma concentrations by approximately 20% have been observed with doses of 130 mg/m2 oxaliplatin injection dosed every weeks. Because platinum-containing species are eliminated primarily through the kidney, clearance of these products may be decreased by coadministration of potentially nephrotoxic compounds; although, this has not been specifically studied [see Clinical Pharmacology (12.3)].

GERIATRIC USE SECTION.


8.5 Geriatric Use. No significant effect of age on the clearance of ultrafilterable platinum has been observed. In the adjuvant therapy colon cancer randomized clinical trial, [see Clinical Studies (14)] 723 patients treated with oxaliplatin injection and infusional 5-fluorouracil/leucovorin were <65 years and 400 patients were >=65 years. descriptive subgroup analysis demonstrated that the improvement in DFS for the oxaliplatin injection combination arm compared to the infusional 5-fluorouracil/leucovorin alone arm appeared to be maintained across genders. The effect of oxaliplatin injection in patients >=65 years of age was not conclusive. Insufficient subgroup sizes prevented analysis by race. Patients >= 65 years of age receiving the oxaliplatin injection combination therapy experienced more grade and granulocytopenia than patients 65 years of age (45% versus 39%). In the previously untreated for advanced colorectal cancer randomized clinical trial [see Clinical Studies (14)] of oxaliplatin injection, 160 patients treated with oxaliplatin injection and 5-fluorouracil/leucovorin were 65 years and 99 patients were >=65 years. The same efficacy improvements in response rate, time to tumor progression, and overall survival were observed in the >=65 year old patients as in the overall study population. In the previously treated for advanced colorectal cancer randomized clinical trial [see Clinical Studies (14)] of oxaliplatin injection, 95 patients treated with oxaliplatin injection and 5-fluorouracil/leucovorin were <65 years and 55 patients were >=65 years. The rates of overall adverse reactions, including grade and events, were similar across and within arms in the different age groups in all studies. The incidence of diarrhea, dehydration, hypokalemia, leukopenia, fatigue and syncope were higher in patients >=65 years old. No adjustment to starting dose was required in patients >=65 years old.

See What should tell my doctor before receiving oxaliplatin injection. Numbness, pain, tingling, and/or burning along the nerves. Low white blood cells (neutropenia). Low platelet count (important for clotting and to control bleeding). Low red blood cells (blood cells that carry oxygen to the tissues). Nausea. Changes in liver function tests. Diarrhea. Vomiting. Tiredness. Mouth sores. Cover yourself with blanket while you are getting your oxaliplatin injection infusion.. Do not breathe deeply when exposed to cold air.. Wear warm clothing in cold weather at all times. Cover your mouth and nose with scarf or pull-down cap (ski cap) to warm the air that goes to your lungs.. Wear gloves when taking things from the freezer or refrigerator.. Drink fluids warm or at room temperature.. Always drink through straw.. Do not use ice chips if you have nausea or mouth sores. Ask your doctor about what you can use.. Be aware that most metals are cold to touch, especially in the winter. These include your car door and mailbox. Wear gloves to touch cold objects.. Do not run the air-conditioning at high levels in the house or in the car in hot weather.. If your body gets cold, warm-up the affected part. If your hands get cold, wash them with warm water.. Always let your doctor know before your next treatment how well you did since your last visit.

MECHANISM OF ACTION SECTION.


12.1 Mechanism of Action. Oxaliplatin undergoes nonenzymatic conversion in physiologic solutions to active derivatives via displacement of the labile oxalate ligand. Several transient reactive species are formed, including monoaquo and diaquo DACH platinum, which covalently bind with macromolecules. Both inter- and intrastrand Pt-DNA crosslinks are formed. Crosslinks are formed between the N7 positions of two adjacent guanines (GG), adjacent adenine-guanines (AG), and guanines separated by an intervening nucleotide (GNG). These crosslinks inhibit DNA replication and transcription. Cytotoxicity is cell-cycle nonspecific. In vivo studies have shown antitumor activity of oxaliplatin against colon carcinoma. In combination with 5-fluorouracil, oxaliplatin exhibits in vitro and in vivo antiproliferative activity greater than either compound alone in several tumor models [HT29 (colon), GR (mammary), and L1210 (leukemia)].

NONCLINICAL TOXICOLOGY SECTION.


13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term animal studies have not been performed to evaluate the carcinogenic potential of oxaliplatin. Oxaliplatin was not mutagenic to bacteria (Ames test) but was mutagenic to mammalian cells in vitro (L5178Y mouse lymphoma assay). Oxaliplatin was clastogenic both in vitro (chromosome aberration in human lymphocytes) and in vivo (mouse bone marrow micronucleus assay). In fertility study, male rats were given oxaliplatin at 0, 0.5, 1, or mg/kg/day for five days every 21 days for total of three cycles prior to mating with females that received two cycles of oxaliplatin on the same schedule. dose of mg/kg/day (less than one-seventh the recommended human dose on body surface area basis) did not affect pregnancy rate, but caused developmental mortality (increased early resorptions, decreased live fetuses, decreased live births) and delayed growth (decreased fetal weight). Testicular damage, characterized by degeneration, hypoplasia, and atrophy, was observed in dogs administered oxaliplatin at 0.75 mg/kg/day 5 days every 28 days for three cycles. no effect level was not identified. This daily dose is approximately one-sixth of the recommended human dose on body surface area basis.

NURSING MOTHERS SECTION.


8.3 Nursing Mothers. It is not known whether oxaliplatin injection or its derivatives are excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from oxaliplatin injection, decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

OVERDOSAGE SECTION.


10 OVERDOSAGE. There is no known antidote for oxaliplatin injection overdose. In addition to thrombocytopenia, the anticipated complications of an oxaliplatin injection overdose include hypersensitivity reaction, myelosuppression, nausea, vomiting, diarrhea and neurotoxicity. Several cases of overdoses have been reported with oxaliplatin injection. Adverse reactions observed were Grade thrombocytopenia (<25,000/mm3) without any bleeding, anemia, sensory neuropathy such as paresthesia, dysesthesia, laryngospasm and facial muscle spasms, gastrointestinal disorders such as nausea, vomiting, stomatitis, flatulence, abdomen enlarged and Grade intestinal obstruction, Grade dehydration, dyspnea, wheezing, chest pain, respiratory failure, severe bradycardia and death. Patients suspected of receiving an overdose should be monitored, and supportive treatment should be administered. The maximum dose of oxaliplatin that has been administered in single infusion is 825 mg.

PEDIATRIC USE SECTION.


8.4 Pediatric Use. The effectiveness of oxaliplatin in children has not been established. Oxaliplatin has been tested in Phase and Phase trials in 235 patients ages months to 22 years with solid tumors (see below) and no significant activity observed. In Phase 1/2 study, oxaliplatin was administered as 2-hour intravenous infusion on Days 1, and 15 every weeks (1 cycle), for maximum of cycles, to 43 patients with refractory or relapsed malignant solid tumors, mainly neuroblastoma and osteosarcoma. Twenty eight pediatric patients in the Phase study received oxaliplatin at dose levels starting at 40 mg/m2 with escalation to 110 mg/m2. The dose limiting toxicity (DLT) was sensory neuropathy at the 110 mg/m2 dose. Fifteen patients received oxaliplatin at dose of 90 mg/m2 intravenous in the Phase portion of the study. At this dose, paresthesia (60%, G3/4: 7%), fever (40%, G3/4: 7%) and thrombocytopenia (40%, G3/4: 27%) were the main adverse reactions. No responses were observed. In second Phase study, oxaliplatin was administered to 26 pediatric patients as 2-hour intravenous infusion on day every weeks (1 cycle) at dose levels starting at 100 mg/m2 with escalation to 160 mg/m2, for maximum of cycles. In separate cohort, oxaliplatin 85 mg/m2 was administered on day every weeks, for maximum of doses. Patients had metastatic or unresectable solid tumors mainly neuroblastoma and ganglioneuroblastoma. No responses were observed. The DLT was sensory neuropathy at the 160 mg/m2 dose. Based on these studies, oxaliplatin 130 mg/m2 as 2-hour intravenous infusion on day every weeks (1 cycle) was used in subsequent Phase II studies. dose of 85 mg/m2 on day every weeks was also found to be tolerable. In one Phase study, 43 pediatric patients with recurrent or refractory embryonal CNS tumors received oxaliplatin 130 mg/m2 every weeks for maximum of 12 months in absence of progressive disease or unacceptable toxicity. In patients 10 kg the oxaliplatin dose used was 4.3 mg/kg. The most common adverse reactions reported were leukopenia (67%, G3/4: 12%), anemia (65%, G3/4: 5%), thrombocytopenia (65%, G3/4: 26%), vomiting (65%, G3/4: 7%), neutropenia (58%, G3/4: 16%) and sensory neuropathy (40%, G3/4: 5%). One partial response was observed. In second Phase study, 123 pediatric patients with recurrent solid tumors, including neuroblastoma, osteosarcoma, Ewing sarcoma or peripheral PNET, ependymoma, rhabdomyosarcoma, hepatoblastoma, high grade astrocytoma, Brain stem glioma, low grade astrocytoma, malignant germ cell tumor and other tumors of interest received oxaliplatin 130 mg/m2 every weeks for maximum of 12 months or 17 cycles. In patients 12 months old the oxaliplatin dose used was 4.3 mg/kg. The most common adverse reactions reported were sensory neuropathy (52%, G3/4: 12%), thrombocytopenia (37%, G3/4: 17%), anemia (37%, G3/4: 9%), vomiting (26%, G3/4: 4%), ALT increased (24%, G3/4: 6%), AST increased (24%, G3/4: 2%), and nausea (23%, G3/4: 3%). Two partial responses were observed. The pharmacokinetic parameters of ultrafiltrable platinum have been evaluated in 105 pediatric patients during the first cycle. The mean clearance in pediatric patients estimated by the population pharmacokinetic analysis was 4.7 L/h. The inter-patient variability of platinum clearance in pediatric cancer patients was 41%. Mean platinum pharmacokinetic parameters in ultrafiltrate were Cmax of 0.75 +- 0.24 mcg/mL, AUC0-48 of 7.52 +- 5.07 mcg.h/mL and AUCinf of 8.83 +- 1.57 mcg.h/mL at 85 mg/m2 of oxaliplatin and Cmax of 1.1 +- 0.43 mcg/mL, AUC0-48 of 9.74 +- 2.52 mcg.h/mL and AUCinf of 17.3 +- 5.34 mcg.h/mL at 130 mg/m2 of oxaliplatin.

PHARMACOKINETICS SECTION.


12.3 Pharmacokinetics. The reactive oxaliplatin derivatives are present as fraction of the unbound platinum in plasma ultrafiltrate. The decline of ultrafilterable platinum levels following oxaliplatin administration is triphasic, characterized by two relatively short distribution phases (t1/2; 0.43 hours and t1/2; 16.8 hours) and long terminal elimination phase (t1/2; 391 hours). Pharmacokinetic parameters obtained after single 2-hour intravenous infusion of oxaliplatin injection at dose of 85 mg/m2 expressed as ultrafilterable platinum were Cmax of 0.814 mcg/mL and volume of distribution of 440 L. Interpatient and intrapatient variability in ultrafilterable platinum exposure (AUC0-48hr) assessed over cycles was moderate to low (23% and 6%, respectively). pharmacodynamic relationship between platinum ultrafiltrate levels and clinical safety and effectiveness has not been established. Distribution At the end of 2-hour infusion of oxaliplatin injection, approximately 15% of the administered platinum is present in the systemic circulation. The remaining 85% is rapidly distributed into tissues or eliminated in the urine. In patients, plasma protein binding of platinum is irreversible and is greater than 90%. The main binding proteins are albumin and gamma-globulins. Platinum also binds irreversibly and accumulates (approximately 2-fold) in erythrocytes, where it appears to have no relevant activity. No platinum accumulation was observed in plasma ultrafiltrate following 85 mg/m2 every two weeks. Metabolism Oxaliplatin undergoes rapid and extensive nonenzymatic biotransformation. There is no evidence of cytochrome P450-mediated metabolism in vitro. Up to 17 platinum-containing derivatives have been observed in plasma ultrafiltrate samples from patients, including several cytotoxic species (monochloro DACH platinum, dichloro DACH platinum, and monoaquo and diaquo DACH platinum) and number of noncytotoxic, conjugated species. Elimination The major route of platinum elimination is renal excretion. At five days after single 2-hour infusion of oxaliplatin injection, urinary elimination accounted for about 54% of the platinum eliminated, with fecal excretion accounting for only about 2%. Platinum was cleared from plasma at rate (10 to 17 L/h) that was similar to or exceeded the average human glomerular filtration rate (GFR; 7.5 L/h). There was no significant effect of gender on the clearance of ultrafilterable platinum. The renal clearance of ultrafilterable platinum is significantly correlated with GFR. Pharmacokinetics in Special Populations Pediatric [See Use In Specific Patient Populations (8.4)]. Renal Impairment study was conducted in 38 patients with advanced GI cancer and varying degrees of renal impairment. Patients in the normal (creatinine clearance (CrCL) 80 mL/min, = 11), mild (CrCL 50 to 80 mL/min, = 13), and moderate (CrCL 30 to 49 mL/min, = 10) groups were treated with 85 mg/m2 oxaliplatin injection and those in the severe (CrCL 30 mL/min, = 4) group were treated with 65 mg/m2 oxaliplatin injection. The mean AUC of unbound platinum was 40%, 95%, and 342% higher in the mild, moderate, and severe groups, respectively, than in the normal group. Mean Cmax of unbound platinum appeared to be similar among the normal, mild and moderate renal function groups, but was 38% higher in the severe group than in the normal group. Caution should be exercised in renally impaired patients [see Use in Specific Populations (8.6)]. The starting dose of oxaliplatin injection should be reduced in patients with severe renal impairment [see Dosage and Administration (2.2)]. Drug Drug Interactions No pharmacokinetic interaction between 85 mg/m2 of oxaliplatin injection and infusional 5-fluorouracil has been observed in patients treated every weeks, but increases of 5-fluorouracil plasma concentrations by approximately 20% have been observed with doses of 130 mg/m2 of oxaliplatin injection administered every weeks. In vitro, platinum was not displaced from plasma proteins by the following medications: erythromycin, salicylate, sodium valproate, granisetron, and paclitaxel. In vitro, oxaliplatin is not metabolized by, nor does it inhibit, human cytochrome P450 isoenzymes. No P450-mediated drug-drug interactions are therefore anticipated in patients. Since platinum-containing species are eliminated primarily through the kidney, clearance of these products may be decreased by coadministration of potentially nephrotoxic compounds, although this has not been specifically studied.

PREGNANCY SECTION.


8.1 Pregnancy. Pregnancy Category Based on direct interaction with DNA, oxaliplatin injection may cause fetal harm when administered to pregnant woman. There are no adequate and well-controlled studies of oxaliplatin injection in pregnant women. Reproductive toxicity studies in rats demonstrated adverse effects on fertility and embryo-fetal development at maternal doses that were below the recommended human dose based on body surface area. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Women of childbearing potential should be advised to avoid becoming pregnant and use effective contraception while receiving treatment with oxaliplatin injection. Pregnant rats were administered oxaliplatin at less than one-tenth the recommended human dose based on body surface area during gestation days to (pre-implantation), to 10, or 11 to 16 (during organogenesis). Oxaliplatin caused developmental mortality (increased early resorptions) when administered on days to 10 and 11 to 16 and adversely affected fetal growth (decreased fetal weight, delayed ossification) when administered on days to 10. Administration of oxaliplatin to male and female rats prior to mating resulted in 97% post-implantation loss in animals that received approximately one-seventh the recommended human dose based on the body surface area.

In patients 10 kg the oxaliplatin dose used was 4.3 mg/kg. The most common adverse reactions reported were leukopenia (67%, G3/4: 12%), anemia (65%, G3/4: 5%), thrombocytopenia (65%, G3/4: 26%), vomiting (65%, G3/4: 7%), neutropenia (58%, G3/4: 16%) and sensory neuropathy (40%, G3/4: 5%). One partial response was observed. In second Phase study, 123 pediatric patients with recurrent solid tumors, including neuroblastoma, osteosarcoma, Ewing sarcoma or peripheral PNET, ependymoma, rhabdomyosarcoma, hepatoblastoma, high grade astrocytoma, Brain stem glioma, low grade astrocytoma, malignant germ cell tumor and other tumors of interest received oxaliplatin 130 mg/m2 every weeks for maximum of 12 months or 17 cycles. In patients 12 months old the oxaliplatin dose used was 4.3 mg/kg.

Mean platinum pharmacokinetic parameters in ultrafiltrate were Cmax of 0.75 +- 0.24 mcg/mL, AUC0-48 of 7.52 +- 5.07 mcg.h/mL and AUCinf of 8.83 +- 1.57 mcg.h/mL at 85 mg/m2 of oxaliplatin and Cmax of 1.1 +- 0.43 mcg/mL, AUC0-48 of 9.74 +- 2.52 mcg.h/mL and AUCinf of 17.3 +- 5.34 mcg.h/mL at 130 mg/m2 of oxaliplatin.. 8.5 Geriatric Use. No significant effect of age on the clearance of ultrafilterable platinum has been observed. In the adjuvant therapy colon cancer randomized clinical trial, [see Clinical Studies (14)] 723 patients treated with oxaliplatin injection and infusional 5-fluorouracil/leucovorin were <65 years and 400 patients were >=65 years. descriptive subgroup analysis demonstrated that the improvement in DFS for the oxaliplatin injection combination arm compared to the infusional 5-fluorouracil/leucovorin alone arm appeared to be maintained across genders. The effect of oxaliplatin injection in patients >=65 years of age was not conclusive. Insufficient subgroup sizes prevented analysis by race. Patients >= 65 years of age receiving the oxaliplatin injection combination therapy experienced more grade and granulocytopenia than patients 65 years of age (45% versus 39%). In the previously untreated for advanced colorectal cancer randomized clinical trial [see Clinical Studies (14)] of oxaliplatin injection, 160 patients treated with oxaliplatin injection and 5-fluorouracil/leucovorin were 65 years and 99 patients were >=65 years. The same efficacy improvements in response rate, time to tumor progression, and overall survival were observed in the >=65 year old patients as in the overall study population. In the previously treated for advanced colorectal cancer randomized clinical trial [see Clinical Studies (14)] of oxaliplatin injection, 95 patients treated with oxaliplatin injection and 5-fluorouracil/leucovorin were <65 years and 55 patients were >=65 years. The rates of overall adverse reactions, including grade and events, were similar across and within arms in the different age groups in all studies. The incidence of diarrhea, dehydration, hypokalemia, leukopenia, fatigue and syncope were higher in patients >=65 years old. No adjustment to starting dose was required in patients >=65 years old.. 8.6 Patients with Renal Impairment. The exposure (AUC) of unbound platinum in plasma ultrafiltrate tends to increase in renally impaired patients [see Pharmacokinetics (12.3)]. Caution and close monitoring should be exercised when oxaliplatin injection is administered to patients with renal impairment. The starting oxaliplatin injection dose does not need to be reduced in patients with mild (creatinine clearance 50 to 80 mL/min) or moderate (creatinine clearance 30 to 49 mL/min) renal impairment. However, the starting dose of oxaliplatin injection should be reduced in patients with severe renal impairment (creatinine clearance 30 mL/min) [see Dosage and Administration (2.2)].

See boxed warning Grade 3/4 hypersensitivity, including anaphylactic/anaphylactoid reactions, to oxaliplatin injection has been observed in to 3% of colon cancer patients. These allergic reactions which can be fatal, can occur within minutes of administration and at any cycle, and were similar in nature and severity to those reported with other platinum-containing compounds, such as rash, urticaria, erythema, pruritus, and, rarely, bronchospasm and hypotension. The symptoms associated with hypersensitivity reactions reported in the previously untreated patients were urticaria, pruritus, flushing of the face, diarrhea associated with oxaliplatin infusion, shortness of breath, bronchospasm, diaphoresis, chest pains, hypotension, disorientation and syncope. These reactions are usually managed with standard epinephrine, corticosteroid, antihistamine therapy, and require discontinuation of therapy. Rechallenge is contraindicated in these patients [see Contraindications (4)]. Drug-related deaths associated with platinum compounds from anaphylaxis have been reported.. 5.2 Neurologic Toxicity. NeuropathyOxaliplatin injection is associated with two types of neuropathy:An acute, reversible, primarily peripheral, sensory neuropathy that is of early onset, occurring within hours or one to two days of dosing, that resolves within 14 days, and that frequently recurs with further dosing. The symptoms may be precipitated or exacerbated by exposure to cold temperature or cold objects and they usually present as transient paresthesia, dysesthesia and hypoesthesia in the hands, feet, perioral area, or throat. Jaw spasm, abnormal tongue sensation, dysarthria, eye pain, and feeling of chest pressure have also been observed. The acute, reversible pattern of sensory neuropathy was observed in about 56% of study patients who received oxaliplatin injection with 5-fluorouracil/leucovorin. In any individual cycle acute neurotoxicity was observed in approximately 30% of patients. In adjuvant patients the median cycle of onset for grade peripheral sensory neuropathy was in the previously treated patients the median number of cycles administered on the oxaliplatin injection with 5-fluorouracil/leucovorin combination arm was 6. An acute syndrome of pharyngolaryngeal dysesthesia seen in to 2% (grade 3/4) of patients previously untreated for advanced colorectal cancer, and the previously treated patients, is characterized by subjective sensations of dysphagia or dyspnea, without any laryngospasm or bronchospasm (no stridor or wheezing). Ice (mucositis prophylaxis) should be avoided during the infusion of oxaliplatin injection because cold temperature can exacerbate acute neurological symptoms.A persistent (>14 days), primarily peripheral, sensory neuropathy that is usually characterized by paresthesias, dysesthesias, hypoesthesias, but may also include deficits in proprioception that can interfere with daily activities (e.g., writing, buttoning, swallowing, and difficulty walking from impaired proprioception). These forms of neuropathy occurred in 48% of the study patients receiving oxaliplatin injection with 5-fluorouracil/leucovorin. Persistent neuropathy can occur without any prior acute neuropathy event. The majority of the patients (80%) who developed grade persistent neuropathy progressed from prior Grade or events. These symptoms may improve in some patients upon discontinuation of oxaliplatin injection.In the adjuvant colon cancer trial, neuropathy was graded using prelisted module derived from the Neuro-Sensory section of the National Cancer Institute Common Toxicity Criteria (NCI CTC) scale, Version 1, as follows: Table - NCI CTC Grading for Neuropathy in Adjuvant Patients GradeDefinitionGrade No change or none Grade Mild paresthesias, loss of deep tendon reflexes Grade Mild or moderate objective sensory loss, moderate paresthesias Grade Severe objective sensory loss or paresthesias that interfere with function Grade Not applicable Peripheral sensory neuropathy was reported in adjuvant patients treated with the oxaliplatin injection combination with frequency of 92% (all grades) and 13% (grade 3). At the 28-day follow-up after the last treatment cycle, 60% of all patients had any grade (Grade 1=40%, Grade 2=16%, Grade 3=5%) peripheral sensory neuropathy decreasing to 39% at months follow-up (Grade 1=31%, Grade 2=7%, Grade 3=1%) and 21% at 18 months of follow-up (Grade 1=17%, Grade 2=3%, Grade 3=1%). In the advanced colorectal cancer studies, neuropathy was graded using study-specific neurotoxicity scale, which was different from the NCI CTC scale, Version (see below). Table - Grading Scale for Paresthesias/Dysesthesias in Advanced Colorectal Cancer Patients GradeDefinitionGrade Resolved and did not interfere with functioning Grade Interfered with function but not daily activities Grade Pain or functional impairment that interfered with daily activities Grade Persistent impairment that is disabling or life-threatening Overall, neuropathy was reported in patients previously untreated for advanced colorectal cancer in 82% (all grades) and 19% (grade 3/4), and in the previously treated patients in 74% (all grades) and 7% (grade 3/4) events. Information regarding reversibility of neuropathy was not available from the trial for patients who had not been previously treated for colorectal cancer. Reversible Posterior Leukoencephalopathy Syndrome Reversible Posterior Leukoencephalopathy Syndrome (RPLS, also known as PRES, Posterior Reversible Encephalopathy Syndrome) has been observed in clinical trials (< 0.1%) and postmarketing experience. Signs and symptoms of RPLS could be headache, altered mental functioning, seizures, abnormal vision from blurriness to blindness, associated or not with hypertension [see Adverse Reactions (6.2)]. Diagnosis of RPLS is based upon confirmation by brain imaging.. 5.3 Severe Neutropenia. Grade or neutropenia occurred in 41-44% of patients with colorectal cancer treated with oxaliplatin injection in combination with 5-fluorouracil (5-FU) and leucovorin compared to 5% with 5-FU plus leucovorin alone. Sepsis, neutropenic sepsis and septic shock have been reported in patients treated with oxaliplatin injection, including fatal outcomes [see Adverse Reactions (6.1)].Delay oxaliplatin injection until neutrophils are >= 1.5 109/L. Withhold oxaliplatin injection for sepsis or septic shock. Dose reduce oxaliplatin injection after recovery from Grade neutropenia or febrile neutropenia [see Dosage and Administration (2.2)].. 5.4 Pulmonary Toxicity. Oxaliplatin injection has been associated with pulmonary fibrosis (<1% of study patients), which may be fatal. The combined incidence of cough and dyspnea was 7.4% (any grade) and <1% (grade 3) with no grade events in the oxaliplatin injection plus infusional 5-fluorouracil/leucovorin arm compared to 4.5% (any grade) and no grade and 0.1% grade events in the infusional 5-fluorouracil/leucovorin alone arm in adjuvant colon cancer patients. In this study, one patient died from eosinophilic pneumonia in the oxaliplatin injection combination arm. The combined incidence of cough, dyspnea and hypoxia was 43% (any grade) and 7% (grade and 4) in the oxaliplatin injection plus 5-fluorouracil/leucovorin arm compared to 32% (any grade) and 5% (grade and 4) in the irinotecan plus 5-fluorouracil/leucovorin arm of unknown duration for patients with previously untreated colorectal cancer. In case of unexplained respiratory symptoms such as non-productive cough, dyspnea, crackles, or radiological pulmonary infiltrates, oxaliplatin injection should be discontinued until further pulmonary investigation excludes interstitial lung disease or pulmonary fibrosis.. 5.5 Hepatotoxicity. Hepatotoxicity as evidenced in the adjuvant study, by increase in transaminases (57% vs. 34%) and alkaline phosphatase (42% vs. 20%) was observed more commonly in the oxaliplatin injection combination arm than in the control arm. The incidence of increased bilirubin was similar on both arms. Changes noted on liver biopsies include: peliosis, nodular regenerative hyperplasia or sinusoidal alterations, perisinusoidal fibrosis, and veno-occlusive lesions. Hepatic vascular disorders should be considered, and if appropriate, should be investigated in case of abnormal liver function test results or portal hypertension, which cannot be explained by liver metastases [see Clinical Trials Experience (6.1)]. 5.6 Cardiovascular Toxicity. QT prolongation and ventricular arrhythmias including fatal Torsade de Pointes have been reported in postmarketing experiences following oxaliplatin injection administration. ECG monitoring is recommended if therapy is initiated in patients with congestive heart failure, bradyarrhythmias, drugs known to prolong the QT interval, including Class Ia and III antiarrhythmics, and electrolyte abnormalities. Correct hypokalemia or hypomagnesemia prior to initiating oxaliplatin injection and monitor these electrolytes periodically during therapy. Avoid oxaliplatin injection in patients with congenital long QT syndrome [see Adverse Reactions (6.2)].. 5.7 Rhabdomyolysis. Rhabdomyolysis, including fatal cases, has been reported in patients treated with oxaliplatin injection. Discontinue oxaliplatin injection if any signs or symptoms of rhabdomyolysis occur. [see Adverse Reactions (6.2)]. 5.8 Use in Pregnancy. Pregnancy Category Oxaliplatin injection may cause fetal harm when administered to pregnant woman. There are no adequate and well-controlled studies of oxaliplatin injection in pregnant women. Women of childbearing potential should be advised to avoid becoming pregnant while receiving treatment with oxaliplatin injection. [see Use in Specific Populations (8.1)]. 5.9 Recommended Laboratory Tests. Standard monitoring of the white blood cell count with differential, hemoglobin, platelet count, and blood chemistries (including ALT, AST, bilirubin and creatinine) is recommended before each oxaliplatin injection cycle [see Dosage and Administration (2)]. There have been reports while on study and from postmarketing surveillance of prolonged prothrombin time and INR occasionally associated with hemorrhage in patients who received oxaliplatin injection plus 5-fluorouracil/leucovorin while on anticoagulants. Patients receiving oxaliplatin injection plus 5-fluorouracil/leucovorin and requiring oral anticoagulants may require closer monitoring.
