CLINICAL STUDIES SECTION.


14 CLINICAL STUDIES. 14.1 Ovarian Cancer. Maintenance Treatment of Recurrent Ovarian CancerThe efficacy of Rubraca was investigated in ARIEL3 (NCT01968213), double-blind, multicenter clinical trial in which 564 patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who were in response to platinum-based chemotherapy were randomized (2:1) to receive Rubraca tablets 600 mg orally twice daily (n=375) or placebo (n=189). Treatment was continued until disease progression or unacceptable toxicity. All patients had achieved response (complete or partial) to their most recent platinum-based chemotherapy. Randomization was stratified by best response to last platinum (complete or partial), time to progression following the penultimate platinum therapy (6 to <= 12 months and 12 months), and tumor biomarker status. The major efficacy outcome was investigator-assessed progression-free survival (PFS) evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1 (v1.1).The median age was 61 years (range: 39 to 84) for patients receiving Rubraca and 62 years (range: 36 to 85) for those on placebo; the majority were White (80%); and 100% had an ECOG performance status of or 1. All patients had received at least two prior platinum-based chemotherapies (range: to 7). total of 34% of patients were in complete response (CR) to their most recent therapy. The progression-free interval to penultimate platinum was 6-12 months in 40% of patients and 12 months in 60%. Prior bevacizumab therapy was reported for 22% of patients who received Rubraca and 23% of patients who received placebo. Measurable disease was present at baseline in 37% of patients.Tumor tissue samples were tested using clinical trial assay (CTA) (N=564), and the FoundationFocus(TM) CDx BRCA LOH test (n=518). Of the samples evaluated with both tests, homologous recombination deficiency (HRD) positive status (as defined by the presence of deleterious BRCA mutation or high genomic loss of heterozygosity) was confirmed by the FoundationFocus(TM) CDx BRCA LOH test for 94% (313/332) of HRD-positive patients determined by the CTA; and of these, tumor BRCA (tBRCA) mutant status was confirmed by the FoundationFocus(TM) CDx BRCA LOH test for 99% (177/178) of tBRCA-positive patients determined by the CTA. Blood samples for 94% (186/196) of the tBRCA patients were evaluated using central blood germline BRCA test. Based on these results, 70% (130/186) of the tBRCA patients had germline BRCA mutation and 30% (56/186) had somatic BRCA mutation.ARIEL3 demonstrated statistically significant improvement in PFS for patients randomized to Rubraca as compared with placebo in all patients, and in the HRD and tBRCA subgroups. Results from blinded independent radiology review were consistent. At the time of the analysis of PFS, overall survival (OS) data were not mature (with 22% of events).Efficacy results are summarized in Table and Figures 1, 2, and 3.Table 8.

Treatment of BRCA-mutated Ovarian Cancer After or More ChemotherapiesThe efficacy of Rubraca was investigated in 106 patients in two multicenter, single-arm, open-label clinical trials, Study 10 (NCT01482715) and ARIEL2 (NCT01891344), in patients with advanced BRCA-mutant ovarian cancer who had progressed after or more prior chemotherapies. All 106 patients received Rubraca 600 mg orally twice daily as monotherapy until disease progression or unacceptable toxicity. Objective response rate (ORR) and duration of response (DOR) were assessed by the investigator and IRR according to RECIST v1.1.The median age of the patients was 59 years (range: 33 to 84), the majority were White (78%), and 100% had an ECOG performance status of or 1. All patients had received at least two prior platinum-based chemotherapies and 43% had received or more prior lines of platinum-based chemotherapy. There were 18/106 patients (17%) who had deleterious BRCA mutations detected in tumor tissue and not in whole blood specimens. Tumor BRCA mutation status was verified retrospectively in 96% (64/67) of the patients for whom tumor tissue sample was available by the companion diagnostic FoundationFocus(TM) CDxBRCA test, which is FDA approved for selection of patients for Rubraca treatment.Efficacy results are summarized in Table 9.Table 9.

Investigator-assessed ORR was 66% (52/79; 95% CI [54, 76]) in platinum-sensitive patients, 25% (5/20; 95% CI [9, 49]) in platinum-resistant patients, and 0% (0/7; 95% CI [0, 41]) in platinum-refractory patients. ORR was similar for patients with BRCA1 gene mutation or BRCA2 gene mutation.. 14.2 Metastatic Castration-Resistant Prostate Cancer with BRCA mutations. The efficacy of Rubraca was investigated in TRITON2 (NCT02952534), an ongoing multi-center, single arm clinical trial in patients with BRCA-mutated mCRPC who had been treated with androgen receptor-directed therapy and taxane-based chemotherapy. There were 115 patients with either germline or somatic BRCA mutations enrolled in TRITON2, of whom 62 patients had measurable disease at baseline by independent radiology review (IRR). Patients received Rubraca 600 mg orally twice daily until disease progression or unacceptable toxicity. Patients also received concomitant GnRH analog or had prior bilateral orchiectomy. Objective response rate (ORR) and duration of response (DOR) were assessed in patients with measurable disease by blinded IRR and by the investigator according to modified RECIST v1.1/ Prostate Cancer Working Group (PCWG3) criteria.For the 62 patients with measurable disease at baseline, the median age was 73 years (range 52 to 88); the majority were White (73%) and 10% were Black; and 98% of patients had an ECOG performance status of or 1. All patients had received at least one prior androgen receptor-directed therapy, 34% had received prior androgen receptor-directed therapies and 2% had received prior androgen receptor-directed therapies, and all patients also received prior taxane chemotherapy. Eighteen percent of patients had lung and 21% had liver metastases at baseline. Twenty-four percent had metastases to lymph nodes alone. Forty percent had 10 or more bone lesions at baseline.All 62 patients had deleterious somatic or germline BRCA mutation detected from either central plasma (26%), central tissue (32%), or local (42%) testing. Of the 62 patients, 66% had somatic BRCA mutation, 34% had germline BRCA mutation, 85% had BRCA2 mutation, and 15% had BRCA1 mutation.The major efficacy outcomes of the study were confirmed ORR by IRR using modified RECIST v1.1/PCWG3 criteria and DOR. Efficacy results of TRITON2 are provided in Table 10. The ORR by IRR was similar in patients with germline versus somatic BRCA mutation.Table 10.

(6.1). 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.The pooled safety population in the WARNINGS AND PRECAUTIONS section reflect exposure to Rubraca at 600 mg BID in 1146 patients in Study10 (CO-338-010), ARIEL2, ARIEL3, and TRITON2.. Maintenance Treatment of Recurrent Ovarian CancerThe safety of Rubraca for the maintenance treatment of patients with epithelial ovarian, fallopian tube, or primary peritoneal cancer was investigated in ARIEL3, randomized (2:1), double-blind, placebo-controlled study in which 561 patients received either Rubraca 600 mg BID (n=372) or placebo (n=189) until disease progression or unacceptable toxicity. The median duration of study treatment was 8.3 months (range: 1 month to 35 months) for patients who received Rubraca and 5.5 months for patients who received placebo.Dose interruptions due to an adverse reaction of any grade occurred in 65% of patients receiving Rubraca and 10% of those receiving placebo; dose reductions due to an adverse reaction occurred in 55% of Rubraca patients and 4% of placebo patients. The most frequent adverse reactions leading to dose interruption or dose reduction of Rubraca were thrombocytopenia (18%), anemia (17%), nausea (15%), and fatigue/asthenia (13%). Discontinuation due to adverse reactions occurred in 15% of Rubraca patients and 2% of placebo patients. Specific adverse reactions that most frequently led to discontinuation in patients treated with Rubraca were anemia (3%), thrombocytopenia (3%) and nausea (3%).

Treatment of BRCA-mutated mCRPC after Androgen Receptor-directed Therapy and ChemotherapyThe safety of Rubraca 600 mg twice daily was evaluated in single arm trial (TRITON2) [see Clinical Studies (14.2)]. TRITON2 enrolled 209 patients with HRD-positive mCRPC, including 115 with BRCA-mutated mCRPC. Among the patients with BRCA-mutated mCRPC, the median duration of Rubraca treatment was 6.5 months (range 0.5 to 26.7).There were (1.7%) patients with adverse reactions leading to death, one each attributed to acute respiratory distress syndrome and pneumonia.Dose interruptions due to an adverse reaction occurred in 57% of patients receiving Rubraca. Adverse reactions requiring dose interruption in >3% of patients included anemia, thrombocytopenia, asthenia/fatigue, nausea, vomiting, neutropenia, ALT/AST increased, creatinine increased, decreased appetite, acute kidney injury, and hypophosphatemia.Dose reductions due to an adverse reaction occurred in 41% of patients receiving Rubraca. Adverse reactions requiring dose reduction in >3% of patients were anemia (14%), asthenia/fatigue (10%), thrombocytopenia (7%), nausea (6%), decreased appetite (4%), and rash (3%).Discontinuation due to adverse reactions occurred in 8% of patients receiving Rubraca. None of the adverse reactions leading to discontinuation of Rubraca (ECG QT prolonged, acute respiratory distress syndrome, anemia, balance disorder, cardiac failure, decreased appetite/fatigue/weight decreased, leukopenia/neutropenia, ALT/AST increased, and pneumonia) occurred in more than one patient (<1%).Tables and summarize the adverse reactions and laboratory abnormalities, respectively, in patients with BRCA-mutated mCRPC in TRITON2.Table 6.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenicity studies have not been conducted with rucaparib.Rucaparib was clastogenic in an in vitro chromosomal aberration assay in cultured human lymphocytes. The clastogenic response in mitotically-stimulated cells was anticipated based on the mechanism of action of rucaparib and indicates potential genotoxicity in humans. Rucaparib was not mutagenic in bacterial reverse mutation (Ames) test.Fertility studies with rucaparib have not been conducted. In 3-month repeat-dose general toxicology studies, rucaparib had no effects on male and female reproductive organs at doses up to 100 mg/kg/day and 20 mg/kg/day in rats and dogs, respectively. These dose levels resulted in systemic exposures of approximately 0.3 and 0.09 times the human exposure (AUC0-24h), respectively, at the recommended dose.

CLINICAL PHARMACOLOGY SECTION.


12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Rucaparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP-1, PARP-2, and PARP-3, which play role in DNULL repair. In vitro studies have shown that rucaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNULL complexes resulting in DNULL damage, apoptosis, and cancer cell death. Increased rucaparib-induced cytotoxicity and anti-tumor activity was observed in tumor cell lines with deficiencies in BRCA1/2 and other DNULL repair genes. Rucaparib has been shown to decrease tumor growth in mouse xenograft models of human cancer with or without deficiencies in BRCA.. 12.2 Pharmacodynamics. The pharmacodynamic response of rucaparib has not been characterized.. Cardiac ElectrophysiologyThe effect of multiple doses of Rubraca on QTc interval was evaluated in an open-label single-arm study in 56 patients with solid tumors who were administered continuous doses of Rubraca ranging from 40 mg once daily (0.03 times the approved recommended dose) to 840 mg twice daily (1.4 times the approved recommended dose). positive concentration-QTc relationship was observed. The mean QTcF increase from baseline (90% confidence interval [CI]) in population pharmacokinetics estimated 95th percentile Cmax (3019 ng/mL) at steady state of 600 mg rucaparib twice daily was 14.9 msec (11.1-18.7 msec).. 12.3 Pharmacokinetics. The pharmacokinetic profile of rucaparib was characterized in patients with cancer. Rucaparib demonstrated linear pharmacokinetics over dose range from 240 to 840 mg twice daily with time-independence and dose-proportionality. The mean steady-state rucaparib Cmax was 1940 ng/mL (54% coefficient of variation [CV]) and AUC0-12h was 16900 h.ng/mL (54% CV) at the approved recommended dose. Accumulation was 3.5 to 6.2 fold.. AbsorptionThe median Tmax was 1.9 hours at the approved recommended dose. The mean absolute bioavailability of rucaparib immediate-release tablet was 36% with range from 30% to 45%.Following high-fat meal, the Cmax was increased by 20% and AUC0-24h was increased by 38%, and Tmax was delayed by 2.5 hours, as compared to dosing under fasted conditions [see Dosage and Administration (2.2)].. DistributionRucaparib had steady-state volume of distribution of 113 to 262 following single intravenous dose of 12 mg to 40 mg rucaparib.In vitro, the protein binding of rucaparib was 70% in human plasma at therapeutic concentrations. Rucaparib preferentially distributed to red blood cells with blood-to-plasma concentration ratio of 1.83.. EliminationThe apparent clearance ranged from 15.3 to 79.2 L/hour, following rucaparib 600 mg orally twice daily. The clearance ranged from 13.9 to 18.4 L/hour, following single intravenous dose of rucaparib 12 mg to 40 mg. The mean terminal T1/2 of rucaparib was 25.9 hours following single oral dose of 600 mg rucaparib.. MetabolismIn vitro, rucaparib had low metabolic turnover rate and was metabolized primarily by CYP2D6 and to lesser extent by CYP1A2 and CYP3A4.Following administration of single oral dose of [14C]-rucaparib to patients with solid tumors, unchanged rucaparib accounted for 64.0% of the radioactivity in plasma. Oxidation, N-demethylation, N-methylation, and glucuronidation were the major metabolic pathways for rucaparib. Rucaparib accounted for 44.9% and 94.9% of radioactivity in urine and feces, respectively.. Specific Populations. Age, Race, Sex, and Body WeightBased on population pharmacokinetic analyses, age, race, sex, and body weight did not have clinically meaningful effect on rucaparib exposure.. Renal ImpairmentIn patients who received Rubraca 600 mg twice daily, those with mild renal impairment (N=148; baseline CLcr between 60 and 89 mL/min, as estimated by the Cockcroft-Gault method) and those with moderate renal impairment (N=72; CLcr between 30 and 59 mL/min) showed approximately 15% and 32% higher steady-state AUC, respectively, compared to patients with normal renal function (N=143; CLcr greater than or equal to 90 mL/min). The pharmacokinetic characteristics of rucaparib in patients with CLcr less than 30 mL/min or patients on dialysis are unknown..

LACTATION SECTION.


8.2 Lactation. Risk SummaryThere is no information regarding the presence of rucaparib in human milk, or on its effects on milk production or the breast-fed child. Because of the potential for serious adverse reactions in breast-fed children from Rubraca, advise lactating women not to breastfeed during treatment with Rubraca and for weeks following the last dose.

MECHANISM OF ACTION SECTION.


12.1 Mechanism of Action. Rucaparib is an inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP-1, PARP-2, and PARP-3, which play role in DNULL repair. In vitro studies have shown that rucaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNULL complexes resulting in DNULL damage, apoptosis, and cancer cell death. Increased rucaparib-induced cytotoxicity and anti-tumor activity was observed in tumor cell lines with deficiencies in BRCA1/2 and other DNULL repair genes. Rucaparib has been shown to decrease tumor growth in mouse xenograft models of human cancer with or without deficiencies in BRCA.

NONCLINICAL TOXICOLOGY SECTION.


13 NONCLINICAL TOXICOLOGY. 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Carcinogenicity studies have not been conducted with rucaparib.Rucaparib was clastogenic in an in vitro chromosomal aberration assay in cultured human lymphocytes. The clastogenic response in mitotically-stimulated cells was anticipated based on the mechanism of action of rucaparib and indicates potential genotoxicity in humans. Rucaparib was not mutagenic in bacterial reverse mutation (Ames) test.Fertility studies with rucaparib have not been conducted. In 3-month repeat-dose general toxicology studies, rucaparib had no effects on male and female reproductive organs at doses up to 100 mg/kg/day and 20 mg/kg/day in rats and dogs, respectively. These dose levels resulted in systemic exposures of approximately 0.3 and 0.09 times the human exposure (AUC0-24h), respectively, at the recommended dose.

OVERDOSAGE SECTION.


10 OVERDOSAGE. There is no specific treatment in the event of Rubraca overdose, and symptoms of overdose are not established. In the event of suspected overdose, physicians should follow general supportive measures and should treat symptomatically.

PHARMACODYNULLMICS SECTION.


12.2 Pharmacodynamics. The pharmacodynamic response of rucaparib has not been characterized.. Cardiac ElectrophysiologyThe effect of multiple doses of Rubraca on QTc interval was evaluated in an open-label single-arm study in 56 patients with solid tumors who were administered continuous doses of Rubraca ranging from 40 mg once daily (0.03 times the approved recommended dose) to 840 mg twice daily (1.4 times the approved recommended dose). positive concentration-QTc relationship was observed. The mean QTcF increase from baseline (90% confidence interval [CI]) in population pharmacokinetics estimated 95th percentile Cmax (3019 ng/mL) at steady state of 600 mg rucaparib twice daily was 14.9 msec (11.1-18.7 msec).

PHARMACOKINETICS SECTION.


12.3 Pharmacokinetics. The pharmacokinetic profile of rucaparib was characterized in patients with cancer. Rucaparib demonstrated linear pharmacokinetics over dose range from 240 to 840 mg twice daily with time-independence and dose-proportionality. The mean steady-state rucaparib Cmax was 1940 ng/mL (54% coefficient of variation [CV]) and AUC0-12h was 16900 h.ng/mL (54% CV) at the approved recommended dose. Accumulation was 3.5 to 6.2 fold.. AbsorptionThe median Tmax was 1.9 hours at the approved recommended dose. The mean absolute bioavailability of rucaparib immediate-release tablet was 36% with range from 30% to 45%.Following high-fat meal, the Cmax was increased by 20% and AUC0-24h was increased by 38%, and Tmax was delayed by 2.5 hours, as compared to dosing under fasted conditions [see Dosage and Administration (2.2)].. DistributionRucaparib had steady-state volume of distribution of 113 to 262 following single intravenous dose of 12 mg to 40 mg rucaparib.In vitro, the protein binding of rucaparib was 70% in human plasma at therapeutic concentrations. Rucaparib preferentially distributed to red blood cells with blood-to-plasma concentration ratio of 1.83.. EliminationThe apparent clearance ranged from 15.3 to 79.2 L/hour, following rucaparib 600 mg orally twice daily. The clearance ranged from 13.9 to 18.4 L/hour, following single intravenous dose of rucaparib 12 mg to 40 mg. The mean terminal T1/2 of rucaparib was 25.9 hours following single oral dose of 600 mg rucaparib.. MetabolismIn vitro, rucaparib had low metabolic turnover rate and was metabolized primarily by CYP2D6 and to lesser extent by CYP1A2 and CYP3A4.Following administration of single oral dose of [14C]-rucaparib to patients with solid tumors, unchanged rucaparib accounted for 64.0% of the radioactivity in plasma. Oxidation, N-demethylation, N-methylation, and glucuronidation were the major metabolic pathways for rucaparib. Rucaparib accounted for 44.9% and 94.9% of radioactivity in urine and feces, respectively.. Specific Populations. Age, Race, Sex, and Body WeightBased on population pharmacokinetic analyses, age, race, sex, and body weight did not have clinically meaningful effect on rucaparib exposure..

PREGNULLNCY SECTION.


8.1 Pregnancy. Risk SummaryBased on findings from animal studies and its mechanism of action, Rubraca can cause fetal harm when administered to pregnant women. There are no available data in pregnant women to inform the drug-associated risk. In an animal reproduction study, administration of rucaparib to pregnant rats during organogenesis resulted in embryo-fetal death at maternal exposures that were 0.04 times the AUC0-24h in patients receiving the recommended dose of 600 mg twice daily [see Data]. Apprise pregnant women of the potential risk to fetus.The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.. Data. Animal DataIn dose range-finding embryo-fetal development study, pregnant rats received oral doses of 50, 150, 500, or 1000 mg/kg/day of rucaparib during the period of organogenesis. Post-implantation loss (100% early resorptions) was observed in all animals at doses greater than or equal to 50 mg/kg/day (with maternal systemic exposures approximately 0.04 times the human exposure at the recommended dose based on AUC0-24h).

USE IN SPECIFIC POPULATIONS SECTION.


8 USE IN SPECIFIC POPULATIONS. Lactation: Advise women not to breastfeed. (8.2). Lactation: Advise women not to breastfeed. (8.2). 8.1 Pregnancy. Risk SummaryBased on findings from animal studies and its mechanism of action, Rubraca can cause fetal harm when administered to pregnant women. There are no available data in pregnant women to inform the drug-associated risk. In an animal reproduction study, administration of rucaparib to pregnant rats during organogenesis resulted in embryo-fetal death at maternal exposures that were 0.04 times the AUC0-24h in patients receiving the recommended dose of 600 mg twice daily [see Data]. Apprise pregnant women of the potential risk to fetus.The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.. Data. Animal DataIn dose range-finding embryo-fetal development study, pregnant rats received oral doses of 50, 150, 500, or 1000 mg/kg/day of rucaparib during the period of organogenesis. Post-implantation loss (100% early resorptions) was observed in all animals at doses greater than or equal to 50 mg/kg/day (with maternal systemic exposures approximately 0.04 times the human exposure at the recommended dose based on AUC0-24h).. 8.2 Lactation. Risk SummaryThere is no information regarding the presence of rucaparib in human milk, or on its effects on milk production or the breast-fed child. Because of the potential for serious adverse reactions in breast-fed children from Rubraca, advise lactating women not to breastfeed during treatment with Rubraca and for weeks following the last dose.. 8.3 Females and Males of Reproductive Potential. Pregnancy TestingPregnancy testing is recommended for females of reproductive potential prior to initiating Rubraca.. Contraception. FemalesRubraca can cause fetal harm when administered to pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment and for months following the last dose of Rubraca.. MalesBased on findings in genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective methods of contraception during treatment and for months following last dose of Rubraca. Advise male patients not to donate sperm during therapy and for months following the last dose of Rubraca [see Use in Specific Populations (8.1) and Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use. The safety and effectiveness of Rubraca in pediatric patients have not been established.. 8.5 Geriatric Use. Of the 937 patients with ovarian cancer who received Rubraca in ARIEL3, ARIEL2, and Study 10, 41% were age 65 or older and 10% were 75 years or older. No major differences in safety were observed between younger and older patients with ovarian cancer.Of the 209 patients with mCRPC who received Rubraca in TRITON2, 77% were age 65 or older and 33% were 75 years or older. No major differences in safety were observed between younger and older patients with mCRPC.. 8.6 Hepatic Impairment. No starting dose adjustment is recommended for patients with mild hepatic impairment (total bilirubin less than or equal to upper limit of normal [ULN] and AST greater than ULN, or total bilirubin between 1.0 to 1.5 times ULN and any AST). No recommendation for starting dose adjustment is available for patients with moderate to severe hepatic impairment (total bilirubin greater than 1.5 times ULN) due to lack of data [See Clinical Pharmacology (12.3)]. 8.7 Renal Impairment. No starting dose adjustment is recommended for patients with mild to moderate renal impairment (baseline creatinine clearance [CLcr] between 30 and 89 mL/min, as estimated by the Cockcroft-Gault method). There is no recommended starting dose for patients with CLcr less than 30 mL/min or patients on dialysis due to lack of data [See Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.


5 WARNINGS AND PRECAUTIONS. Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): MDS/AML occurred in patients exposed to RUBRACA, and some cases were fatal. Monitor patients for hematological toxicity at baseline and monthly thereafter. Interrupt or reduce the dose based on severity of reaction. Discontinue if MDS/AML is confirmed. (2.3, 5.1)Embryo-Fetal Toxicity: RUBRACA can cause fetal harm. Advise of the potential risk to fetus and to use effective contraception. (5.2, 8.1, 8.3). Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): MDS/AML occurred in patients exposed to RUBRACA, and some cases were fatal. Monitor patients for hematological toxicity at baseline and monthly thereafter. Interrupt or reduce the dose based on severity of reaction. Discontinue if MDS/AML is confirmed. (2.3, 5.1). Embryo-Fetal Toxicity: RUBRACA can cause fetal harm. Advise of the potential risk to fetus and to use effective contraception. (5.2, 8.1, 8.3). 5.1 Myelodysplastic Syndrome/Acute Myeloid Leukemia. Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) occur in patients treated with Rubraca, and are potentially fatal adverse reactions. In 1146 treated patients [see Adverse Reactions (6.1)], MDS/AML occurred in 20 patients (1.7%), including those in long term follow-up. Of these, occurred during treatment or during the 28 day safety follow-up (0.7%). The duration of Rubraca treatment prior to the diagnosis of MDS/AML ranged from month to approximately 53 months. The cases were typical of secondary MDS/cancer therapy-related AML; in all cases, patients had received previous platinum-containing chemotherapy regimens and/or other DNULL damaging agents.In TRITON2, MDS/AML was not observed in patients with mCRPC (n=209) regardless of homologous recombination deficiency (HRD) mutation [see Adverse Reactions (6.1)].Do not start Rubraca until patients have recovered from hematological toxicity caused by previous chemotherapy (<= Grade 1). Monitor complete blood counts for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities (> weeks), interrupt Rubraca or reduce dose according to Table [see Dosage and Administration (2.3)] and monitor blood counts weekly until recovery. If the levels have not recovered to Grade or less after weeks or if MDS/AML is suspected, refer the patient to hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Rubraca.. 5.2 Embryo-Fetal Toxicity. Rubraca can cause fetal harm when administered to pregnant woman based on its mechanism of action and findings from animal studies. In an animal reproduction study, administration of rucaparib to pregnant rats during the period of organogenesis resulted in embryo-fetal death at exposures that were 0.04 times the AUC0-24h in patients receiving the recommended human dose of 600 mg twice daily. Apprise pregnant women of the potential risk to fetus. Advise females of reproductive potential to use effective contraception during treatment and for months following the last dose of Rubraca [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)]. Based on findings from genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for months following the last dose of Rubraca [see Use in Specific Populations (8.1, 8.3)].
