Minor bleeding was classified as clinically overt bleeding that did not meet criteria for major bleeding.At the end of the six-month study, total of 46 (13.6%) patients in the FRAGMIN arm and 62 (18.5%) patients in the OAC arm experienced any bleeding event. One bleeding event (hemoptysis in patient in the FRAGMIN arm at Day 71) was fatal.Table 11 Bleeding Reactions (Major and Any) (As treated population)Patients with multiple bleeding episodes within any time interval were counted only once in that interval.

Elevations of Serum TransaminasesIn FRAGMIN clinical trials supporting non-cancer indications, where hepatic transaminases were measured, asymptomatic increases in transaminase levels (SGOT/AST and SGPT/ALT) greater than three times the upper limit of normal of the laboratory reference range were seen in 4.7% and 4.2%, respectively, of patients during treatment with FRAGMIN.In the FRAGMIN clinical trial of patients with cancer and acute symptomatic venous thromboembolism treated with FRAGMIN for up to months, asymptomatic increases in transaminase levels, AST and ALT, greater than three times the upper limit of normal of the laboratory reference range were reported in 8.9% and 9.5% of patients, respectively. The frequencies of Grades and increases in AST and ALT, as classified by the National Cancer Institute, Common Toxicity Criteria (NCI-CTC) Scoring System, were 3% and 3.8%, respectively. Grades 2, & combined have been reported in 12% and 14% of patients, respectively.. Other. Allergic Reactions: Allergic reactions (i.e., pruritus, rash, fever, injection site reaction, bullous eruption) have occurred. Cases of anaphylactoid reactions have been reported.. Local Reactions: Pain at the injection site was reported in 4.5% of patients treated with FRAGMIN 5,000 IU once daily vs 11.8% of patients treated with heparin 5,000 twice daily in the abdominal surgery trials. In the hip replacement trials, pain at injection site was reported in 12% of patients treated with FRAGMIN 5,000 IU once daily vs 13% of patients treated with heparin 5,000 three times day.. Pediatric Patients with Symptomatic VTEThe data below reflect exposure to FRAGMIN from two studies in pediatric patients from newborn to less than 18 years of age with or without cancer and symptomatic VTE (n 50). Patients were started on FRAGMIN using age and weight-based dosing via subcutaneous injection twice daily. Anti-Xa levels were measured prior to the 4th dose and then periodically to determine whether dose adjustments were required, using 25 IU/kg increments, to achieve target anti-Xa level of 0.5 1.0 IU/ml. The median time on treatment with FRAGMIN was 86 days (range to 170 days).In pediatric patients with symptomatic VTE, the most common (greater than 10%) adverse reactions were injection site bruising (30%), contusion (12%), and epistaxis (10%).Major bleeding was defined as any fatal bleeding, clinically overt bleeding with decrease in hemoglobin of >=2gm/dl in 24 hours, overt bleeding deemed by the attending physician to be unrelated to the subjects underlying condition and accompanied by blood product administration, overt bleeding that was retroperitoneal, intracranial, intraspinal, intraocular, or intraarticular, or overt bleeding deemed by the attending physician to necessitate permanent discontinuation of trial medication. Major bleeding (intestinal hematoma) occurred in one patient (2%). Discontinuation due to adverse reactions occurred in 12% of patients, most often due to thrombocytopenia (4%).. 6.2Postmarketing Experience. The following adverse reactions have been identified during postapproval use of FRAGMIN. 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.Since first international market introduction in 1985, there have been more than 15 reports of epidural or spinal hematoma formation with concurrent use of FRAGMIN and spinal/epidural anesthesia or spinal puncture. The majority of patients had postoperative indwelling epidural catheters placed for analgesia or received additional drugs affecting hemostasis. In some cases the hematoma resulted in long-term or permanent paralysis (partial or complete) [see Boxed Warning].Musculoskeletal System: OsteoporosisSkin or subcutaneous tissues disorders: Skin necrosis, cases of alopecia reported that improved on drug discontinuation.

BOXED WARNING SECTION.

WARNING: SPINAL/EPIDURAL HEMATOMAS. Epidural or spinal hematomas may occur in patients who are anticoagulated with low molecular weight heparins (LMWH) or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include: Use of indwelling epidural cathetersConcomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants. history of traumatic or repeated epidural or spinal puncturesA history of spinal deformity or spinal surgery Optimal timing between the administration of FRAGMIN and neuraxial procedures is not knownMonitor patients frequently for signs and symptoms of neurological impairment.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility. Dalteparin sodium has not been tested for its carcinogenic potential in long-term animal studies. It was not mutagenic in the in vitro Ames Test, mouse lymphoma cell forward mutation test and human lymphocyte chromosomal aberration test and in the in vivo mouse micronucleus test. Dalteparin sodium at subcutaneous doses up to 1,200 IU/kg (7,080 IU/m2) did not affect the fertility or reproductive performance of male and female rats.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1Mechanism of Action. Dalteparin is low molecular weight heparin with antithrombotic properties. It acts by enhancing the inhibition of Factor Xa and thrombin by antithrombin. In humans, dalteparin potentiates preferentially the inhibition of coagulation Factor Xa, while only slightly affecting the activated partial thromboplastin time (APTT).. 12.2 Pharmacodynamics. Doses of FRAGMIN Injection of up to 10,000 anti-Xa IU administered subcutaneously as single dose or two 5,000 IU doses 12 hours apart to healthy subjects did not produce significant change in platelet aggregation, fibrinolysis, or global clotting tests such as prothrombin time (PT), thrombin time (TT) or APTT. Subcutaneous administration of doses of 5,000 IU twice daily of FRAGMIN for seven consecutive days to patients undergoing abdominal surgery did not markedly affect APTT, Platelet Factor (PF4), or lipoprotein lipase.. 12.3 Pharmacokinetics. AdultsMean peak levels of plasma anti-Xa activity following single subcutaneous doses of 2,500, 5,000 and 10,000 IU were 0.19 +- 0.04, 0.41 +- 0.07 and 0.82 +- 0.10 IU/mL, respectively, and were attained in about hours in most subjects. Absolute bioavailability in healthy volunteers, measured as the anti-Xa activity, was 87 +- 6%. Increasing the dose from 2,500 to 10,000 IU resulted in an overall increase in anti-Xa AUC that was greater than proportional by about one-third.Peak anti-Xa activity increased more or less linearly with dose over the same dose range. There appeared to be no appreciable accumulation of anti-Xa activity with twice-daily dosing of 100 IU/kg subcutaneously for up to days.The volume of distribution for dalteparin anti-Xa activity was 40 to 60 mL/kg. The mean plasma clearances of dalteparin anti-Xa activity in normal volunteers following single intravenous bolus doses of 30 and 120 anti-Xa IU/kg were 24.6 +- 5.4 and 15.6 +- 2.4 mL/hr/kg, respectively. The corresponding mean disposition half-lives were 1.47 +- 0.3 and 2.5 +- 0.3 hours.Following intravenous doses of 40 and 60 IU/kg, mean terminal half-lives were 2.1 +- 0.3 and 2.3 +- 0.4 hours, respectively. Longer apparent terminal half-lives (3 to hours) are observed following subcutaneous dosing, possibly due to delayed absorption. In patients with chronic renal insufficiency requiring hemodialysis, the mean terminal half-life of anti-Xa activity following single intravenous dose of 5,000 IU FRAGMIN was 5.7 +- 2.0 hours, i.e., considerably longer than values observed in healthy volunteers, therefore, greater accumulation can be expected in these patients.. Pediatric PatientsThe pharmacokinetics of twice-daily subcutaneous dalteparin, measured as anti-Xa activity, was characterized in 89 pediatric patients with or without cancer from two clinical studies and observational study. Dalteparin pharmacokinetics (PK) were described by 1-compartment model with linear absorption and elimination and PK parameters are shown in Table 12. After correcting for the body weight, clearance (CL/F) decreased with increasing age, while volume of distribution at steady-state (Vd/F) remained similar. The mean elimination half-life increased with age.Table 12 Pharmacokinetic Parameters of Dalteparin in Pediatric PopulationParameter3 Weeks to <8 Weeks>=8 Weeks to <2 Years>=2 Years to <8 Years>=8 Years to <12 Years>=12 Years to <20 YearsAbbreviations: CL=clearance; F=absolute bioavailability; SD=standard deviation; 1/2 =elimination half-life; Vd=volume of distribution.Median Age (range) (years)0.06 (0.04 0.14)0.5 (0.2 1.91)4.47 (2.01 7.6)9.62 (8.01 10.5)15.9 (12.0 19.5)Derived Mean (SD) CL/F (mL/h/kg)55.8 (3.91)40.4 (8.49)26.7 (4.75)22.4 (3.40)18.8 (3.01)Derived Mean (SD) Vd/F (mL/kg)181 (15.3)175 (55.3)160 (25.6)165 (27.3)171 (38.9)Derived Mean (SD) 1/2 (h)2.25 (0.173)3.02 (0.688)4.27 (1.05)5.11 (0.509)6.28 (0.937).

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1Prophylaxis of Ischemic Complications in Unstable Angina and Non-Q-Wave Myocardial Infarction. In double-blind, randomized, placebo-controlled clinical trial, patients who recently experienced unstable angina with EKG changes or non-Q-wave myocardial infarction (MI) were randomized to FRAGMIN Injection 120 IU/kg or placebo every 12 hours subcutaneously. In this trial, unstable angina was defined to include only angina with EKG changes. All patients, except when contraindicated, were treated concurrently with aspirin (75 mg once daily) and beta blockers. Treatment was initiated within 72 hours of the event (the majority of patients received treatment within 24 hours) and continued for to days. total of 1,506 patients were enrolled and treated; 746 received FRAGMIN and 760 received placebo. The mean age of the study population was 68 years (range 40 to 90 years) and the majority of patients were white (99.7%) and male (63.9%). The combined incidence of the endpoint of death or myocardial infarction was lower for FRAGMIN compared with placebo at days after initiation of therapy. These results were observed in an analysis of all-randomized and all-treated patients. The combined incidence of death, MI, need for intravenous heparin or intravenous. nitroglycerin, and revascularization was also lower for FRAGMIN than for placebo (see Table 13).Table 13 Efficacy of FRAGMIN in the Prophylaxis of Ischemic Complications in Unstable Angina and Non-Q-Wave Myocardial InfarctionIndicationDosing RegimenFRAGMIN120 IU/kg/every 12 hr subcutaneousn (%)Placeboevery 12 hr subcutaneousn (%)All Treated Unstable Angina and Non-Q-Wave MI Patients746760Primary Endpoints 6 day timepointDeath, MI13/741 (1.8)p-value 0.001 36/757 (4.8)Secondary Endpoints 6 day timepointDeath, MI, intravenous heparin, i.v. nitroglycerin, Revascularization59/739 (8.0) 106/756 (14.0)In second randomized, controlled trial designed to evaluate long-term treatment with FRAGMIN (days to 45), data were also collected comparing 1-week (5 to days) treatment of FRAGMIN 120 IU/kg every 12 hours subcutaneously with heparin at an APTT-adjusted dosage. All patients, except when contraindicated, were treated concurrently with aspirin (100 to 165 mg per day). Of the 1,499 patients enrolled, 1,482 patients were treated; 751 received FRAGMIN and 731 received heparin. The mean age of the study population was 64 years (range 25 to 92 years) and the majority of patients were white (96.0%) and male (64.2%). The incidence of the combined endpoint of death, myocardial infarction, or recurrent angina during this 1-week treatment period (5 to days) was 9.3% for FRAGMIN and 7.6% for heparin (p 0.323).. 14.2Prophylaxis of Deep Vein Thrombosis in Patients Following Hip Replacement Surgery. In an open-label randomized study, FRAGMIN 5,000 IU administered once daily subcutaneously was compared with warfarin sodium, administered orally, in patients undergoing hip replacement surgery. Treatment with FRAGMIN was initiated with 2,500 IU dose subcutaneously within hours before surgery, followed by 2,500 IU dose subcutaneously the evening of the day of surgery. Then, dosing regimen of FRAGMIN 5,000 IU subcutaneously once daily was initiated on the first postoperative day. The first dose of warfarin sodium was given the evening before surgery, then continued daily at dose adjusted for INR to 3. Treatment in both groups was then continued for to days postoperatively. Of the 580 patients enrolled, 553 were treated and 550 underwent surgery. Of those who underwent surgery, 271 received FRAGMIN and 279 received warfarin sodium. The mean age of the study population was 63 years (range 20 to 92 years) and the majority of patients were white (91.1%) and female (52.9%). The incidence of deep vein thrombosis (DVT), as determined by evaluable venography, was significantly lower for the group treated with FRAGMIN compared with patients treated with warfarin sodium (see Table 14).Table 14 Efficacy of FRAGMIN in the Prophylaxis of Deep Vein Thrombosis Following Hip Replacement SurgeryIndicationDosing RegimenFRAGMIN5,000 IU once dailyThe daily dose on the day of surgery was divided: 2,500 IU was given hours before surgery and again in the evening of the day of surgery. subcutaneousn (%)Warfarin Sodiumonce dailyWarfarin sodium dosage was adjusted to maintain prothrombin time index of 1.4 to 1.5, corresponding to an International Normalized Ratio (INR) of approximately 2.5 oraln (%)All Treated Hip Replacement Surgery Patients271279Treatment Failures in Evaluable PatientsDVT, Total28/192 (14.6)p-value 0.006 49/190 (25.8)Proximal DVT10/192 (5.2)p-value 0.185 16/190 (8.4)PE2/271 (0.7)2/279 (0.7)In second single-center, double-blind study of patients undergoing hip replacement surgery, FRAGMIN 5,000 IU once daily subcutaneously starting the evening before surgery, was compared with heparin 5,000 subcutaneously three times day, starting the morning of surgery. Treatment in both groups was continued for up to days postoperatively. Of the 140 patients enrolled, 139 were treated and 136 underwent surgery. Of those who underwent surgery, 67 received FRAGMIN and 69 received heparin. The mean age of the study population was 69 years (range 42 to 87 years) and the majority of patients were female (58.8%). In the intent-to-treat analysis, the incidence of proximal DVT was significantly lower for patients treated with FRAGMIN compared with patients treated with heparin (6/67 vs 18/69; = 0.012). The incidence of pulmonary embolism detected by lung scan was also significantly lower in the group treated with FRAGMIN (9/67 vs 19/69; = 0.032).A third multi-center, double-blind, randomized study evaluated postoperative dosing regimen of FRAGMIN for thromboprophylaxis following total hip replacement surgery. Patients received either FRAGMIN or warfarin sodium, randomized into one of three treatment groups. One group of patients received the first dose of FRAGMIN 2,500 IU subcutaneous within hours before surgery, followed by another dose of FRAGMIN 2,500 IU subcutaneous at least hours (6.6 +- 2.3 hr) after surgery. Another group received the first dose of FRAGMIN 2,500 IU subcutaneous at least hours (6.6 +- 2.4 hr) after surgery. Then, both of these groups began dosing regimen of FRAGMIN 5,000 IU once daily subcutaneous on postoperative day 1. The third group of patients received warfarin sodium the evening of the day of surgery, then continued daily at dose adjusted to maintain INR to 3. Treatment for all groups was continued for to days postoperatively, after which time all patients underwent bilateral venography.In the total enrolled study population of 1,501 patients, 1,472 patients were treated; 496 received FRAGMIN (first dose before surgery), 487 received FRAGMIN (first dose after surgery) and 489 received warfarin sodium. The mean age of the study population was 63 years (range 18 to 91 years) and the majority of patients were white (94.4%) and female (51.8%).Administration of the first dose of FRAGMIN after surgery was as effective in reducing the incidence of thromboembolic reactions as administration of the first dose of FRAGMIN before surgery (44/336 vs 37/338; =0.448). Both dosing regimens of FRAGMIN were more effective than warfarin sodium in reducing the incidence of thromboembolic reactions following hip replacement surgery.. 14.3Prophylaxis of Deep Vein Thrombosis Following Abdominal Surgery in Patients at Risk for Thromboembolic Complications. Abdominal surgery patients at risk include those who are over 40 years of age, obese, undergoing surgery under general anesthesia lasting longer than 30 minutes, or who have additional risk factors such as malignancy or history of deep vein thrombosis or pulmonary embolism.FRAGMIN administered once daily subcutaneously beginning prior to surgery and continued for to 10 days after surgery, reduced the risk of DVT in patients at risk for thromboembolic complications in two double-blind, randomized, controlled clinical trials performed in patients undergoing major abdominal surgery. In the first study, total of 204 patients were enrolled and treated; 102 received FRAGMIN and 102 received placebo. The mean age of the study population was 64 years (range 40 to 98 years) and the majority of patients were female (54.9%). In the second study, total of 391 patients were enrolled and treated; 195 received FRAGMIN and 196 received heparin. The mean age of the study population was 59 years (range 30 to 88 years) and the majority of patients were female (51.9%). FRAGMIN 2,500 IU was superior to placebo and similar to heparin in reducing the risk of DVT (see Tables 15 and 16).Table 15 Efficacy of FRAGMIN in the Prophylaxis of Deep Vein Thrombosis Following Abdominal SurgeryIndicationDosing RegimenFRAGMIN2,500 IU once daily subcutaneousn (%)Placeboonce daily subcutaneousn (%)All Treated Abdominal Surgery Patients102102Treatment Failures in Evaluable PatientsTotal Thromboembolic Reactions4/91 (4.4)p-value 0.008 16/91 (17.6)Proximal DVT05/91 (5.5)Distal DVT4/91 (4.4)11/91 (12.1)PE02/91 (2.2)Both patients also had DVT, proximal and distal Table 16 Efficacy of FRAGMIN in the Prophylaxis of Deep Vein Thrombosis Following Abdominal SurgeryIndicationDosing RegimenFRAGMIN2,500 IU once daily subcutaneousn (%)Heparin5,000 twice daily subcutaneousn (%)All Treated Abdominal Surgery Patients195196Treatment Failures in Evaluable PatientsTotal Thromboembolic Reactions7/178 (3.9)p-value 0.74 7/174 (4.0)Proximal DVT3/178 (1.7)4/174 (2.3)Distal DVT3/178 (1.7)3/174 (1.7)PE1/178 (0.6)0In third double-blind, randomized study performed in patients undergoing major abdominal surgery with malignancy, FRAGMIN 5,000 IU subcutaneous once daily was compared with FRAGMIN 2,500 IU subcutaneous once daily.

In double-blind, multi-center, randomized, placebo-controlled clinical trial, general medical patients with severely restricted mobility who were at risk of VTE were randomized to receive either FRAGMIN 5,000 IU or placebo subcutaneously once daily during Days to 14 of the study. These patients had an acute medical condition requiring projected hospital stay of at least days, and were confined to bed during waking hours. The study included patients with congestive heart failure (NYHA Class III or IV), acute respiratory failure not requiring ventilatory support, and the following acute conditions with at least one risk factor occurring in >1% of treated patients: acute infection (excluding septic shock), acute rheumatic disorder, acute lumbar or sciatic pain, vertebral compression, or acute arthritis of the lower extremities. Risk factors include >75 years of age, cancer, previous DVT/PE, obesity, and chronic venous insufficiency. total of 3,681 patients were enrolled and treated: 1,848 received FRAGMIN and 1,833 received placebo. The mean age of the study population was 69 years (range 26 to 99 years), 92.1% were white and 51.9% were female. The primary efficacy endpoint was evaluated at Day 21 and was defined as at least one of the following within Days to 21 of the study: asymptomatic DVT (diagnosed by compression ultrasound), confirmed symptomatic DVT, confirmed pulmonary embolism or sudden death. The follow-up extended through Day 90.When given at dose of 5,000 IU once day subcutaneously, FRAGMIN significantly reduced the incidence of thromboembolic reactions including verified DVT by Day 21 (see Table 18). The prophylactic effect was sustained through Day 90.Table 18 Efficacy of FRAGMIN in the Prophylaxis of Deep Vein Thrombosis in Medical Patients with Severely Restricted Mobility During Acute IllnessIndicationDosing RegimenFRAGMIN5,000 IU once daily subcutaneousn (%)Placeboonce daily subcutaneousn (%)All Treated Medical Patients During Acute Illness1,8481,833Treatment failure in evaluable patients(Day 21)Defined as DVT (diagnosed by compression ultrasound at Day 21 3), confirmed symptomatic DVT, confirmed PE or sudden death.

Adult PatientsIn prospective, multi-center, open-label, clinical trial, 676 patients with cancer and newly diagnosed, objectively confirmed acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE) were studied. Patients were randomized to either FRAGMIN 200 IU/kg subcutaneous (max 18,000 IU subcutaneous daily for one month) then 150 IU/kg subcutaneous (max 18,000 IU subcutaneous daily for five months (FRAGMIN arm) or FRAGMIN 200 IU/kg subcutaneous (max 18,000 IU subcutaneous daily for five to seven days and oral anticoagulant for six months (OAC arm). In the OAC arm, oral anticoagulation was adjusted to maintain an INR of to 3. Patients were evaluated for recurrence of symptomatic VTE every two weeks for six months.The median age of patients was 64 years (range: 22 to 89 years); 51.5% of patients were females; 95.3% of patients were Caucasians. Types of tumors were: gastrointestinal tract (23.7%), genito-urinary (21.5%), breast (16%), lung (13.3%), hematological tumors (10.4%), and other tumors (15.1%).A total of 27 (8.0%) and 53 (15.7%) patients in the FRAGMIN and OAC arms, respectively, experienced at least one episode of an objectively confirmed, symptomatic DVT and/or PE during the 6-month study period. Most of the difference occurred during the first month of treatment (see Table 19). The benefit was maintained over the 6-month study period.Table 19 Recurrent VTE in Patients with Cancer (Intention to treat population)Three patients in the FRAGMIN arm and patients in the OAC arm experienced more than VTE over the 6-month study period.

Pediatric Patients The efficacy of FRAGMIN is based on single-arm, open-label, multi-center clinical trial in 38 pediatric patients with or without cancer and symptomatic deep vein thrombosis and/or pulmonary embolism. This study included 26 patients with an active malignancy and 12 patients without cancer. Of the 38 total patients, patients were less than years, patients were to less than years, patients were to less than 12 years, and 17 patients were 12 to less than or equal to 18 years. Patients were treated with FRAGMIN for up to months, with starting doses by age and weight.The efficacy of FRAGMIN was established by the achievement of therapeutic anti-Xa levels by Day of therapy during the dose adjustment period and supported by the number of patients with lack of VTE progression or new VTE.The efficacy population included pediatric patients who achieved therapeutic anti-Xa level (0.5 to IU/mL) in the 7-day dose adjustment period (N 34). The median doses of FRAGMIN (IU/kg) required to achieve therapeutic anti-Xa level during the dose adjustment period are presented in Table 20. Therapeutic anti-Xa levels were achieved within mean of 2.6 days (range: to days).At study completion, 21 patients (62%) achieved resolution of the qualifying VTE, patients (21%) showed regression, patients (6%) showed no change, and no patients showed progression of the qualifying VTE. One patient (3%) experienced new VTE during the study while on treatment.Table 20 Median Doses of FRAGMIN (IU/kg) Associated with Therapeutic Anti-Xa Level (0.5 to IU/mL) by Age Cohort (N 34)Age CohortNMedian Dose (IU/kg)Greater than or equal to weeks to less than years2208Greater than or equal to years to less than years8128Greater than or equal to years to less than 12 years7125Greater than or equal to 12 years to less than or equal to 18 years17117.

Samples for anti-Xa level should be drawn hours after administration of FRAGMIN. Adjust doses in increments of 25 IU/kg to achieve target anti-Xa level between 0.5 and IU/mL. Individualize the maintenance dose of FRAGMIN based on the dose that achieves target anti-Xa level collected hours after administration of FRAGMIN. Monitor anti-Xa level periodically in pediatric patients to maintain anti-Xa level between 0.5 and IU/mL [see Clinical Pharmacology (12.3) and Clinical Studies (14.5)].Whenever possible, administer benzyl alcohol-free formulations (prefilled syringes) in pediatric patients [see Warnings and Precautions (5.3) and Use in Specific Populations (8.4)].. 2.5Dose Reductions for Thrombocytopenia in Adult Patients with Cancer and in Pediatric Patients with Symptomatic VTE. Dose reductions recommended in patients receiving FRAGMIN who experience thrombocytopenia are presented below in Table 6.Table 6Platelet Count less than or equal to 50,000/mm3 Platelet Count equal to 50,000 to 100,000/mm3 AdultsDiscontinue FRAGMIN until platelet count recovers to above 50,000/mm3.Reduce the daily dose of FRAGMIN by 2,500 IU until the platelet count recovers to greater or equal to 100,000/mm3.Children Weeks to less than 17 YearsDiscontinue FRAGMIN until platelet count recovers to above 50,000/mm3.Reduce the daily dose of FRAGMIN by 50% until the platelet count recovers to greater or equal to 100,000/mm3.. 2.6Dose Reductions for Renal Insufficiency in Extended Treatment of Acute Symptomatic VTE in Adult Patients with Cancer. In patients with severely impaired renal function (CrCl <30 mL/min), monitor anti-Xa levels to determine the appropriate FRAGMIN dose. Target anti-Xa range is 0.5-1.5 IU/mL. When monitoring anti-Xa in these patients, perform sampling 4-6 hours after FRAGMIN dosing and only after the patient has received 3-4 doses.. 2.7Administration Latex Allergy: Persons with latex allergies should not handle the FRAGMIN prefilled syringe because the needle shield may contain natural rubber latex which may cause allergic reactions.FRAGMIN is administered by subcutaneous injection. It must not be administered by intramuscular injection.FRAGMIN Injection should not be mixed with other injections or infusions unless specific compatibility data are available that support such mixing.Subcutaneous injection technique: Patients should be sitting or lying down and FRAGMIN administered by deep subcutaneous injection. FRAGMIN may be injected in U-shape area around the navel, the upper outer side of the thigh or the upper outer quadrangle of the buttock. The injection site should be varied daily. When the area around the navel or the thigh is used, using the thumb and forefinger, you must lift up fold of skin while giving the injection. The entire length of the needle should be inserted at 45 to 90 degree angle.Inspect FRAGMIN prefilled syringes and vials visually for particulate matter and discoloration prior to administrationAfter first penetration of the rubber stopper, store the multiple-dose vials at room temperature for up to weeks.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. The use of FRAGMIN in patients receiving oral anticoagulants, platelet inhibitors, and thrombolytic agents may increase the risk of bleeding [see Warnings and Precautions (5)].. The use of FRAGMIN in patients receiving oral anticoagulants, platelet inhibitors, and thrombolytic agents may increase the risk of bleeding (7).

GERIATRIC USE SECTION.

8.5 Geriatric Use. Of the total number of patients in clinical studies of FRAGMIN, 5,516 patients were 65 years of age or older and 2,237 were 75 or older. No overall differences in effectiveness were observed between these subjects and younger subjects. Some studies suggest that the risk of bleeding increases with age. Postmarketing surveillance and literature reports have not revealed additional differences in the safety of FRAGMIN between elderly and younger patients. Give careful attention to dosing intervals and concomitant medications (especially antiplatelet medications) in geriatric patients, particularly in those with low body weight (<45 kg) and those predisposed to decreased renal function [see Warnings and Precautions (5) and Clinical Pharmacology (12)].

INFORMATION FOR PATIENTS SECTION.

17 PATIENT COUNSELING INFORMATION. Risk of Hemorrhage including Spinal/Epidural HematomasIf patients have had neuraxial anesthesia or spinal puncture, and particularly, if they are taking concomitant NSAIDs, platelet inhibitors, or other anticoagulants, inform the patients to watch for signs and symptoms of spinal or epidural hematoma, such as tingling, numbness (especially in the lower limbs) and muscular weakness. If any of these symptoms occur the patient should contact his or her physician immediately.Additionally, the use of aspirin and other NSAIDs may enhance the risk of hemorrhage. Discontinue their use prior to FRAGMIN therapy whenever possible; if co-administration is essential, the patients clinical and laboratory status should be closely monitored [see Drug Interactions (7)].. Inform Patients:of the instructions for injecting FRAGMIN if their therapy is to continue after discharge from the hospitals.it may take them longer than usual to stop bleeding.they may bruise and/or bleed more easily when they are treated with FRAGMIN.they should report any unusual bleeding, bruising, or signs of thrombocytopenia (such as rash of dark red spots under the skin) to their physician [see Warnings and Precautions (5.1, 5.2)].to tell their physicians and dentists they are taking FRAGMIN and/or any other product known to affect bleeding before any surgery is scheduled and before any new drug is taken [see Warnings and Precautions (5.1)].to tell their physicians and dentists of all medications they are taking, including those obtained without prescription, such as aspirin or other NSAIDs [see Drug Interactions (7)].Risks are associated with benzyl alcohol in neonates, infants, and pregnant women [see Warnings and Precautions (5.3) and Use in Specific Populations (8.1)].to tell their physicians and care givers if they are allergic to natural rubber latex [see Dosage and Administration (2.7)]. of the instructions for injecting FRAGMIN if their therapy is to continue after discharge from the hospitals.. it may take them longer than usual to stop bleeding.. they may bruise and/or bleed more easily when they are treated with FRAGMIN.. they should report any unusual bleeding, bruising, or signs of thrombocytopenia (such as rash of dark red spots under the skin) to their physician [see Warnings and Precautions (5.1, 5.2)].. to tell their physicians and dentists they are taking FRAGMIN and/or any other product known to affect bleeding before any surgery is scheduled and before any new drug is taken [see Warnings and Precautions (5.1)].. to tell their physicians and dentists of all medications they are taking, including those obtained without prescription, such as aspirin or other NSAIDs [see Drug Interactions (7)]..

LACTATION SECTION.

8.2 Lactation. Risk SummaryLimited published data indicate that dalteparin is present in human milk in small amounts (see Data). No adverse effects on the breastfed infant have been reported. There are no data on the effects of the drug on milk production. Oral absorption of dalteparin is expected to be low, but the clinical implications, if any, of this small amount of anticoagulant activity on breastfed infant are unknown. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for FRAGMIN and any potential adverse effects on the breastfed child from FRAGMIN or from the underlying maternal condition.. DataA study evaluated samples of maternal blood and breast milk in 15 lactating women receiving prophylactic doses of dalteparin in the immediate postpartum period (days 4-8 after Cesarean-section). The samples were collected before and 3-4 hours after daily injections of 2500 IU dalteparin. Small amounts of anti-Xa activity (range <0.005 to 0.037 IU/mL) in breast milk were detected in 11 of the 15 women. Because this study evaluated colostrum or transitional milk at single timepoint during the 24-hour dosing interval, the clinical relevance of this data is unclear in regard to passage of drug into mature milk and the quantification of drug exposure to the infant over the full dosing interval.

MECHANISM OF ACTION SECTION.

12.1Mechanism of Action. Dalteparin is low molecular weight heparin with antithrombotic properties. It acts by enhancing the inhibition of Factor Xa and thrombin by antithrombin. In humans, dalteparin potentiates preferentially the inhibition of coagulation Factor Xa, while only slightly affecting the activated partial thromboplastin time (APTT).

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY. 13.1Carcinogenesis, Mutagenesis, Impairment of Fertility. Dalteparin sodium has not been tested for its carcinogenic potential in long-term animal studies. It was not mutagenic in the in vitro Ames Test, mouse lymphoma cell forward mutation test and human lymphocyte chromosomal aberration test and in the in vivo mouse micronucleus test. Dalteparin sodium at subcutaneous doses up to 1,200 IU/kg (7,080 IU/m2) did not affect the fertility or reproductive performance of male and female rats.

OVERDOSAGE SECTION.

10 OVERDOSAGE. An excessive dosage of FRAGMIN Injection may lead to hemorrhagic complications. These may generally be stopped by slow intravenous injection of protamine sulfate (1% solution), at dose of mg protamine for every 100 anti-Xa IU of FRAGMIN given. If the APTT measured to hours after the first infusion remains prolonged, second infusion of 0.5 mg protamine sulfate per 100 anti-Xa IU of FRAGMIN may be administered. Even with these additional doses of protamine, the APTT may remain more prolonged than would usually be found following administration of unfractionated heparin. In all cases, the anti-Xa activity is never completely neutralized (maximum about 60 to 75%).Take particular care to avoid overdosage with protamine sulfate. Administration of protamine sulfate can cause severe hypotensive and anaphylactoid reactions. Because fatal reactions, often resembling anaphylaxis, have been reported with protamine sulfate, give protamine sulfate only when resuscitation techniques and treatment for anaphylactic shock are readily available. For additional information, consult the labeling of Protamine Sulfate Injection, USP, products.

PEDIATRIC USE SECTION.

8.4 Pediatric Use. The safety and effectiveness of FRAGMIN for the treatment of symptomatic venous thromboembolism (VTE) in patients have been established in pediatric patients aged month and older.Use of FRAGMIN for this indication is supported by evidence from well-controlled studies in adults with additional pharmacokinetic, pharmacodynamic, efficacy, and safety data from two separate studies in pediatric patients aged month and older with symptomatic VTE [see Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14.5]. The frequency, type and severity of adverse reactions observed were generally consistent with those observed in adults. Use preservative-free FRAGMIN in neonates and infants.Serious adverse reactions including fatal reactions and the gasping syndrome occurred in premature neonates and low-birth weight infants in the neonatal intensive care unit who received benzyl alcohol preserved medications. In these cases, benzyl alcohol dosages of 99 to 234 mg/kg/day produced high levels of benzyl alcohol and its metabolites in the blood and urine (blood levels of benzyl alcohol were 0.61 to 1.378 mmol/L). Additional adverse reactions included gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Preterm, low-birth weight infants may be more likely to develop these reactions because they may be less able to metabolize benzyl alcohol.When prescribing FRAGMIN multiple-dose vials in infants consider the combined daily metabolic load of benzyl alcohol from all sources including FRAGMIN multiple-dose vials (FRAGMIN contains 14 mg of benzyl alcohol per mL) and other drugs containing benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known [see Warnings and Precautions (5.3)].The long-term effects of treatment with FRAGMIN in pediatric patients, including effects on growth and bone metabolism, are unknown.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics. Doses of FRAGMIN Injection of up to 10,000 anti-Xa IU administered subcutaneously as single dose or two 5,000 IU doses 12 hours apart to healthy subjects did not produce significant change in platelet aggregation, fibrinolysis, or global clotting tests such as prothrombin time (PT), thrombin time (TT) or APTT. Subcutaneous administration of doses of 5,000 IU twice daily of FRAGMIN for seven consecutive days to patients undergoing abdominal surgery did not markedly affect APTT, Platelet Factor (PF4), or lipoprotein lipase.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. AdultsMean peak levels of plasma anti-Xa activity following single subcutaneous doses of 2,500, 5,000 and 10,000 IU were 0.19 +- 0.04, 0.41 +- 0.07 and 0.82 +- 0.10 IU/mL, respectively, and were attained in about hours in most subjects. Absolute bioavailability in healthy volunteers, measured as the anti-Xa activity, was 87 +- 6%. Increasing the dose from 2,500 to 10,000 IU resulted in an overall increase in anti-Xa AUC that was greater than proportional by about one-third.Peak anti-Xa activity increased more or less linearly with dose over the same dose range. There appeared to be no appreciable accumulation of anti-Xa activity with twice-daily dosing of 100 IU/kg subcutaneously for up to days.The volume of distribution for dalteparin anti-Xa activity was 40 to 60 mL/kg. The mean plasma clearances of dalteparin anti-Xa activity in normal volunteers following single intravenous bolus doses of 30 and 120 anti-Xa IU/kg were 24.6 +- 5.4 and 15.6 +- 2.4 mL/hr/kg, respectively. The corresponding mean disposition half-lives were 1.47 +- 0.3 and 2.5 +- 0.3 hours.Following intravenous doses of 40 and 60 IU/kg, mean terminal half-lives were 2.1 +- 0.3 and 2.3 +- 0.4 hours, respectively. Longer apparent terminal half-lives (3 to hours) are observed following subcutaneous dosing, possibly due to delayed absorption. In patients with chronic renal insufficiency requiring hemodialysis, the mean terminal half-life of anti-Xa activity following single intravenous dose of 5,000 IU FRAGMIN was 5.7 +- 2.0 hours, i.e., considerably longer than values observed in healthy volunteers, therefore, greater accumulation can be expected in these patients.. Pediatric PatientsThe pharmacokinetics of twice-daily subcutaneous dalteparin, measured as anti-Xa activity, was characterized in 89 pediatric patients with or without cancer from two clinical studies and observational study. Dalteparin pharmacokinetics (PK) were described by 1-compartment model with linear absorption and elimination and PK parameters are shown in Table 12. After correcting for the body weight, clearance (CL/F) decreased with increasing age, while volume of distribution at steady-state (Vd/F) remained similar. The mean elimination half-life increased with age.Table 12 Pharmacokinetic Parameters of Dalteparin in Pediatric PopulationParameter3 Weeks to <8 Weeks>=8 Weeks to <2 Years>=2 Years to <8 Years>=8 Years to <12 Years>=12 Years to <20 YearsAbbreviations: CL=clearance; F=absolute bioavailability; SD=standard deviation; 1/2 =elimination half-life; Vd=volume of distribution.Median Age (range) (years)0.06 (0.04 0.14)0.5 (0.2 1.91)4.47 (2.01 7.6)9.62 (8.01 10.5)15.9 (12.0 19.5)Derived Mean (SD) CL/F (mL/h/kg)55.8 (3.91)40.4 (8.49)26.7 (4.75)22.4 (3.40)18.8 (3.01)Derived Mean (SD) Vd/F (mL/kg)181 (15.3)175 (55.3)160 (25.6)165 (27.3)171 (38.9)Derived Mean (SD) 1/2 (h)2.25 (0.173)3.02 (0.688)4.27 (1.05)5.11 (0.509)6.28 (0.937).

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryAvailable data from published literature and postmarketing reports have not reported clear association with FRAGMIN and adverse developmental outcomes. There are risks to the mother associated with untreated VTE in pregnancy, and potential for adverse effects on the preterm infant when FRAGMIN is used in pregnancy (see Clinical Considerations). In animal reproduction studies, there was no evidence of embryo-fetal toxicity or teratogenicity when dalteparin sodium was administered to pregnant rats and rabbits during organogenesis at doses to times (rats) and times (rabbits) the human dose of 100 IU/kg dalteparin based on the body surface area (see Data). Because animal reproduction studies are not always predictive of human response, FRAGMIN should be used during pregnancy only if clearly needed.The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.. Clinical Considerations. Disease-Associated Maternal and/or Embryo/Fetal RiskPublished data describe that women with previous history of VTE in pregnancy are at higher risk for recurrence during subsequent pregnancies compared to those with no risk factor for VTE (4.5% versus 2.7% respectively, relative risk 1.7, 95% CI: 1.0-2.8).. Fetal/Neonatal Adverse ReactionsCases of gasping syndrome have occurred in premature infants when large amounts of benzyl alcohol have been administered (99-404 mg/kg/day). The 3.8 mL multiple-dose vials of FRAGMIN contain 14 mg/mL of benzyl alcohol [see Warnings and Precautions (5.3)].. Data. Animal DataIn reproductive and developmental toxicity studies, pregnant rats and rabbits received dalteparin sodium during organogenesis at intravenous doses up to 2,400 IU/kg (14,160 IU/m2) (rats) and 4,800 IU/kg (40,800 IU/m2) (rabbits). These exposures were to times (rats) and times (rabbits) the human dose of 100 IU/kg dalteparin based on the body surface area. These studies revealed no evidence of teratogenicity or embryo-fetal toxicity.

Of the total number of patients in clinical studies of FRAGMIN, 5,516 patients were 65 years of age or older and 2,237 were 75 or older. No overall differences in effectiveness were observed between these subjects and younger subjects. Some studies suggest that the risk of bleeding increases with age. Postmarketing surveillance and literature reports have not revealed additional differences in the safety of FRAGMIN between elderly and younger patients. Give careful attention to dosing intervals and concomitant medications (especially antiplatelet medications) in geriatric patients, particularly in those with low body weight (<45 kg) and those predisposed to decreased renal function [see Warnings and Precautions (5) and Clinical Pharmacology (12)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Hemorrhage: Use caution in conditions with increased risk of hemorrhage (5.1)Thrombocytopenia: Monitor thrombocytopenia of any degree closely (5.2)Benzyl Alcohol Preservative: Do not use multiple-dose formulations in neonates and infants as they contain benzyl alcohol (5.3)Laboratory Tests: Periodic blood counts recommended (5.4). Hemorrhage: Use caution in conditions with increased risk of hemorrhage (5.1). Thrombocytopenia: Monitor thrombocytopenia of any degree closely (5.2). Benzyl Alcohol Preservative: Do not use multiple-dose formulations in neonates and infants as they contain benzyl alcohol (5.3). Laboratory Tests: Periodic blood counts recommended (5.4). 5.1Risk of Hemorrhage including Spinal/Epidural Hematomas. Spinal or epidural hemorrhage and subsequent hematomas can occur with the associated use of low molecular weight heparins or heparinoids and neuraxial (spinal/epidural) anesthesia or spinal puncture. The risk of these events is higher with the use of post-operative indwelling epidural catheters, with the concomitant use of additional drugs affecting hemostasis such as NSAIDs, with traumatic or repeated epidural or spinal puncture, or in patients with history of spinal surgery or spinal deformity [see Boxed Warning, Adverse Reactions (6.2), and Drug Interactions (7)].To reduce the potential risk of bleeding associated with the concurrent use of FRAGMIN and epidural or spinal anesthesia/analgesia or spinal puncture, consider the pharmacokinetic profile of FRAGMIN [see Clinical Pharmacology (12.3)]. Placement or removal of an epidural catheter or lumbar puncture is best performed when the anticoagulant effect of FRAGMIN is low; however, the exact timing to reach sufficiently low anticoagulant effect in each patient is not known. No additional hemostasis-altering medications should be administered due to the additive effects.Patients on preoperative FRAGMIN thromboprophylaxis can be assumed to have altered coagulation. The first postoperative FRAGMIN thromboprophylaxis dose (2,500 IU) should be administered to hours postoperatively. The second postoperative dose (2,500 or 5,000 IU) should occur no sooner than 24 hours after the first dose. Placement or removal of catheter should be delayed for at least 12 hours after administration of 2,500 IU once daily of FRAGMIN, at least 15 hours after the administration of 5,000 IU once daily of FRAGMIN, and at least 24 hours after the administration of higher doses (200 IU/kg once daily, 120 IU/kg twice daily) of FRAGMIN. Anti-Xa levels are still detectable at these time points, and these delays are not guarantee that neuraxial hematoma will be avoided.Although specific recommendation for timing of subsequent FRAGMIN dose after catheter removal cannot be made, consider delaying this next dose for at least hours, based on benefit-risk assessment considering both the risk for thrombosis and the risk for bleeding in the context of the procedure and patient risk factors. For patients with creatinine clearance <30mL/minute, additional considerations are necessary because elimination of FRAGMIN may be more prolonged; consider doubling the timing of removal of catheter, at least 24 hours for the lower prescribed dose of FRAGMIN (2,500 IU or 5,000 IU once daily) and at least 48 hours for the higher dose (200 IU/kg once daily, 120 IU/kg twice daily) [see Clinical Pharmacology (12.3)]. Should the physician decide to administer anticoagulation in the context of epidural or spinal anesthesia/analgesia or lumbar puncture, frequent monitoring must be exercised to detect any signs and symptoms of neurological impairment such as midline back pain, sensory and motor deficits (numbness or weakness in lower limbs), bowel and/or bladder dysfunction. Instruct patients to report immediately if they experience any of the above signs or symptoms. If signs or symptoms of spinal hematoma are suspected, initiate urgent diagnosis and treatment including consideration for spinal cord decompression even though such treatment may not prevent or reverse neurological sequelae.Use FRAGMIN with extreme caution in patients who have an increased risk of hemorrhage, such as those with severe uncontrolled hypertension, bacterial endocarditis, congenital or acquired bleeding disorders, active ulceration and angiodysplastic gastrointestinal disease, hemorrhagic stroke, or shortly after brain, spinal or ophthalmological surgery. FRAGMIN may enhance the risk of bleeding in patients with thrombocytopenia or platelet defects; severe liver or kidney insufficiency, hypertensive or diabetic retinopathy, and recent gastrointestinal bleeding. Bleeding can occur at any site during therapy with FRAGMIN.. 5.2Thrombocytopenia. Heparin-induced thrombocytopenia can occur with the administration of FRAGMIN. The incidence of this complication is unknown at present. In clinical practice, cases of thrombocytopenia with thrombosis, amputation and death have been observed [see Contraindications (4)]. Closely monitor thrombocytopenia of any degree.In FRAGMIN clinical trials supporting non-cancer indications, platelet counts of <50,000/mm3 occurred in <1% of patients.In the clinical trial of adult patients with cancer and acute symptomatic VTE treated for up to months in the FRAGMIN treatment arm, platelet counts of <100,000/mm3 occurred in 13.6% of patients, including 6.5% who also had platelet counts less than 50,000/mm3. In the same clinical trial, thrombocytopenia was reported as an adverse event in 10.9% of patients in the FRAGMIN arm and 8.1% of patients in the Oral Anti-Coagulant (OAC) arm. FRAGMIN dose was decreased or interrupted in patients whose platelet counts fell below 100,000/mm3.In the clinical trial of pediatric patients with or without cancer with acute symptomatic VTE treated for up to months with FRAGMIN, platelet counts of <100,000/mm3 occurred in 37% of patients, including 21% who also had platelet counts less than 50,000/mm3. In the same clinical trial, thrombocytopenia was reported as an adverse reaction in 21% of patients. FRAGMIN dose was interrupted in patients whose platelet counts fell below 50,000/mm3.. 5.3Risk of Serious Adverse Reactions in Neonates and Infants due to Benzyl Alcohol Preservative Use preservative-free FRAGMIN in neonates and infants.Serious and fatal adverse reactions including gasping syndrome can occur in neonates and low-birth weight infants treated with medications that contain the preservative benzyl alcohol. The gasping syndrome is characterized by central nervous system depression, metabolic acidosis, and gasping respirations. When prescribing FRAGMIN in infants, consider the combined daily metabolic load of benzyl alcohol from all sources including FRAGMIN multiple-dose vial (contains 14 mg of benzyl alcohol per mL) and other drugs containing benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known [see Use in Specific Populations (8.4)]. Because benzyl alcohol may cross the placenta, use caution when administering FRAGMIN preserved with benzyl alcohol to pregnant women. If anticoagulation with FRAGMIN is needed during pregnancy, use preservative-free formulations where possible [see Use in Specific Populations (8.1)]. 5.4Laboratory Tests. Periodic routine complete blood counts, including platelet count, blood chemistry, and stool occult blood tests are recommended during the course of treatment with FRAGMIN. When administered at recommended prophylaxis doses, routine coagulation tests such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (APTT) are relatively insensitive measures of FRAGMIN activity and, therefore, unsuitable for monitoring the anticoagulant effect of FRAGMIN. Monitor anti-Xa level periodically in pediatric patients. Anti-Xa may be used to monitor the anticoagulant effect of FRAGMIN, such as in patients with severe renal impairment or if abnormal coagulation parameters or bleeding occurs during FRAGMIN therapy.
