Dosage Forms & Strengths

tablet

200mg

300mg

Ovarian Cancer

Maintenance treatment

Indicated for maintenance treatment of recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer in adults who are in a complete or partial response to platinum-based chemotherapy
600 mg PO BID
Continue until disease progression or unacceptable toxicity

Deleterious BRCA mutation

Indicated withdrawn for BRCA mutation-associated epithelial ovarian, fallopian tube, or primary peritoneal cancer after ≥2 chemotherapies

Prostate Cancer

Indicated for treatment of adults with a deleterious BRCA mutation (germline and/or somatic)-associated metastatic castration-resistant prostate cancer (mCRPC) previously treated with androgen receptor-directed therapy and a taxane-based chemotherapy

600 mg PO BID

Continue until disease progression or unacceptable toxicity

Should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently or should have had bilateral orchiectomy

Dosage Modifications

Consider treatment interruption or dosage reduction in the event of adverse reactions

Recommended dose reductions

First dose reduction: 500 mg BID (two 250-mg tablets)
Second dose reduction: 400 mg BID (two 200-mg tablets)
Third dose reduction: 300 mg qDay (one 300-mg tablet)

Hepatic impairment

Mild to moderate (total bilirubin <3 x upper limit of normal [ULN] or AST > ULN): No dosage modification recommended
Severe (total bilirubin > 3 x ULN and any AST): Not studied

Renal impairment

Mild-to-moderate (CrCl 30-89): No dose adjustment required
Severe (CrCl <30 mL/min) or patients on dialysis: Lack of data; no recommendation available

Dosing Considerations

Patient selection

BRCA-mutated advanced ovarian cancer or mCRPC: Select patients based on presence of a deleterious BRCA mutation (germline and/or somatic)
mCRPC: If plasma specimen result is negative, consider performing further genomic testing using tumor specimens as clinically indicated; a negative plasma specimen does not indicate that a tumor is negative for BRCA mutation

Contraindications

None

Cautions

Rare reports of myelodysplastic syndrome/acute myeloid leukemia; evaluate CBC at baseline and monthly thereafter; do not initiate until patients recover from hematological toxicities caused by previous chemotherapy (ie, grade ≤1)

Not recommended in patients with neutrophil counts <1000 cells/mm³; consider alternative therapy when treating patients with neutropenia and acute bacterial skin and skin structure infections

Increases susceptibility to sunburn; advise to use appropriate sun protection

Based on its mechanism of action, can cause fetal harm

Drug interaction overview

Rucaparib inhibits CYP1A2, CYP3A, CYP2C9, and CYP2C19; if concomitant administration unavoidable where minimal concentration changes may lead to serious adverse reactions, decrease the substrate dosage in accordance approved prescribing information
Adjust dosage of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, if clinically indicated
If coadministration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing frequency of INR monitoring

Pregnancy

Based on findings from animal studies and its mechanism of action, can cause fetal harm when administered to pregnant women

There are no available data in pregnant women to inform the drug-associated risk

Pregnancy testing recommended for females of reproductive potential before initiating

Contraception

Females of reproductive potential: Use effective contraception during treatment and for 6 months following the final dose
Males with female partners of reproductive potential: Use effective contraception during treatment and for 3 months following the final dose
Sperm donation: Do not donate sperm during treatment and for 3 months following the final dose

Animal studies

Administration to pregnant rats during organogenesis resulted in embryofetal death at maternal exposure that were 0.04 times the AUC in patients receiving 600 mg BID

Lactation

Unknown if distributed in human breast milk

Advise women not to breastfeed during treatment and for 2 weeks after the final dose

Pregnancy Categories

A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

NA: Information not available.

Mechanism of Action

Inhibitor of poly (ADP-ribose) polymerase (PARP) enzymes, including PARP-1, PARP-2, and PARP-3, which play a role in DNA repair

In vitro studies have shown that rucaparib-induced cytotoxicity may involve inhibition of PARP enzymatic activity and increased formation of PARP-DNA complexes resulting in DNA damage, apoptosis, and cell death

Increased rucaparib-induced cytotoxicity was observed in tumor cell lines with deficiencies in BRCA1/2 and other DNA repair genes

Rucaparib has been shown to decrease tumor growth in mouse xenograft models of human cancer with or without deficiencies in BRCA

Absorption

Absolute bioavailability: 36% (range: 30-45%)

Peak plasma time: 1.9 hr

Steady-state peak plasma concentration: 1940 ng/mL

AUC: 16,900 hr⋅ng/mL

After high-fat meal (compared with fasting): Peak plasma concentration increased by 20%; AUC increased by 38%; peak plasma time delayed by 2.5 hr

Distribution

Vd: 113-262 L

Protein bound: 70%

Metabolism

Metabolized (in vitro) primarily by CYP2D6 and to a lesser extent by CYP1A2 and CYP3A4

Elimination

Half-life: 17-19 hr

Clearance: 15.30-79.2 L/hr

Pharmacogenomics

Steady-state concentrations following 600 mg BID did not differ significantly across CYP2D6 or CYP1A2 genotype subgroups

Oral Administration

May administer with or without food

Missed/vomited dose: Skip missed dose and take next dose at its scheduled time (ie, do not take an extra dose); vomited doses should not be replaced

Storage

Store at controlled room temperature 20-25°C (68-77°F); excursions permitted to 15-30°C (59-86°F)
