RUBRACA

The AUC and C max of rucaparib demonstrated linear pharmacokinetics over a dose range from 240 mg to 840 mg twice daily (0.4 times to 1.4 times the approved recommended dosage). The mean (coefficient of variation [CV]) steady-state rucaparib C max is 1,940 ng/mL (54%) and AUC 0-12h is 16,900 h×ng/mL (54%) at the approved recommended dosage. The mean AUC accumulation ratio is 3.5 to 6.2 fold.

AbsorptionThe median T max (min, max) at the steady state is 1.9 hours (0, 5.98) at the approved recomme...

14.1 Maintenance Treatment of BRCA -mutated Recurrent Ovarian Cancer The efficacy of Rubraca was investigated in ARIEL3 ( NCT01968213 ), a 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 a response (complete or partial) to their most recent platinu...

The following serious adverse reactions are discussed elsewhere in the labeling: Myelodysplastic Syndrome/Acute Myeloid Leukemia [see Warnings and Precautions ( 5.1 )]. Most common adverse reactions (≥10%) among patients with ovarian cancer were nausea, fatigue (including asthenia), anemia, ALT/AST increased, vomiting, diarrhea, decreased appetite, thrombocytopenia, dysgeusia, neutropenia, blood creatinine increased, dyspnea, dizziness, dyspepsia, photosensitivity reaction, and leukopenia.

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 a fetus and to use effective contraception. ( 5.2 , 8.1 , 8.3 ) 5.1 Myelodysplastic Syndr...

7 DRUG INTERACTIONS 7.1 Effect of Rubraca on Other Drugs Certain CYP1A2, CYP3A, CYP2C9, or CYP2C19 Substrates Concomitant administration of Rubraca with CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates can increase the systemic exposure of these substrates [see Clinical Pharmacology ( 12.3 )] , which may increase the frequency or severity of adverse reactions of these substrates. If concomitant admini...
