- Antineoplastic Agent, PARP Inhibitor
Rucaparib is a poly (ADP-ribose) polymerase (PARP) enzyme inhibitor, including PARP1, PARP2, and PARP3. PARP enzymes are involved in DNA transcription, cell cycle regulation, and DNA repair. By inhibiting PARP, rucaparib may cause increased formation of PARP-DNA complexes, resulting in DNA damage, apoptosis, and cancer cell death. Increased cytotoxicity and anti-tumor activity due to rucaparib was observed in tumor cell lines deficient in BRCA1/2 and other DNA repair genes.
Cmax is increased by 20%, AUC is increased by 38%, and Tmax is delayed by 2.5 hours following a high-fat meal (as compared to the fasting state)
113 to 262 L (following a single IV dose of 12 to 40 mg)
Primarily hepatic via CYP2D6; minor pathways include CYP1A2 and CYP3A4
Time to Peak
Terminal: 17 to 19 hours (following a single oral 600 mg dose)
Special Populations: Renal Function Impairment
Patients receiving rucaparib 600 mg twice daily with baseline CrCl 60 to 89 mL/minute and those with CrCl between 30 to 59 mL/minute had approximately 15% and 32% higher steady-state AUC, respectively, compared to patients with normal renal function (CrCl 90 mL/minute or above).
Use: Labeled Indications
Ovarian cancer, advanced: Treatment of deleterious germline and/or somatic BRCA mutation associated (as detected by an approved test) ovarian cancer (epithelial, fallopian tube, or primary peritoneal) in patients who have been treated with 2 or more prior lines of chemotherapy.
Ovarian cancer, recurrent (maintenance): Maintenance treatment of recurrent ovarian cancer (epithelial, fallopian tube, or primary peritoneal) in patients who are in complete or partial response to platinum-based chemotherapy.
There are no contraindications listed in the manufacturer's labeling.
Note: Administer only to patients with deleterious germline and/or somatic BRCA mutation, as detected by an approved test. Rucaparib is associated with a moderate emetic potential; antiemetics may be necessary to prevent nausea and vomiting.
Ovarian cancer, advanced: Oral: 600 mg twice daily until disease progression or unacceptable toxicity (Oza 2017; Swisher 2017).
Ovarian cancer, recurrent (maintenance): Oral: 600 mg twice daily until disease progression or unacceptable toxicity (Coleman 2017).
Missed doses: If a dose is missed, administer the next dose at its scheduled time. Do not repeat or replace a vomited dose.
Refer to adult dosing.
Dosing: Renal Impairment

Concerns related to adverse effects:
• Bone marrow suppression: Anemia, neutropenia, lymphocytopenia, and thrombocytopenia were commonly observed in clinical trials. Monitor blood counts as clinically necessary. Do not initiate treatment until after hematologic recovery (to grade 1 or lower) from prior chemotherapy. Interrupt treatment or reduce the dose for prolonged hematologic toxicity (>4 weeks); monitor blood counts weekly until recovery.
• GI toxicity: Rucaparib is associated with a moderate emetic potential; antiemetics may be needed to prevent nausea and vomiting.
• Secondary malignancy: Myelodysplastic syndrome/acute myeloid leukemia (MDS/AML) has been reported (rarely) in patients receiving rucaparib; may be potentially fatal. Some cases have occurred during or within 28 days following treatment. The duration of therapy prior to diagnosis of MDS/AML ranged from 1 month to ~28 months. The cases were typical of secondary MDS or cancer-therapy related AML and all patients had received prior chemotherapy with platinum agents and/or other DNA-damaging medications. Monitor blood counts (for cytopenia and for clinically significant changes) at baseline and then monthly thereafter. Interrupt treatment and/or reduce the dose for prolonged (>4 weeks) hematological toxicities; monitor blood counts weekly until recovery. If prolonged hematologic toxicity occurs and blood counts do not recover to ≤grade 1 after 4 weeks or if MDS/AML is suspected, further hematology evaluation (including bone marrow and cytogenetic analyses) is necessary. If MDS/AML is confirmed, discontinue therapy.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• BRCA-mutation status: Select patients for the treatment of advanced ovarian cancer (not maintenance therapy) based on the presence of deleterious or suspected deleterious BRCA mutations. Information on approved tests for the detection of BRCA mutations may be found at http://www.fda.gov/companiondiagnostics.
BRCA mutation testing (for treatment of advanced ovarian cancer [not maintenance therapy]); complete blood count at baseline and monthly thereafter, or as clinically indicated (weekly until recovery for prolonged hematologic toxicity); pregnancy test (prior to treatment initiation in females of reproductive potential); monitor for signs/symptoms of MDS/AML. Monitor adherence.
Based on animal reproduction studies and its mechanism of action, rucaparib may be expected to cause adverse events to the fetus. Females of reproductive potential should use effective contraception during therapy and for 6 months after the last dose. Pregnancy testing is recommended prior to therapy initiation in females of reproductive potential.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience nausea, vomiting, constipation, diarrhea, abdominal pain, abdominal edema, mouth irritation, mouth sores, change in taste, lack of appetite, headache, rhinitis, pharyngitis, common cold symptoms, insomnia, or dizziness. Have patient report immediately to prescriber signs of infection, signs of bleeding (vomiting blood or vomit that looks like coffee grounds; coughing up blood; hematuria; black, red, or tarry stools; bleeding from the gums; abnormal vaginal bleeding; bruises without a reason or that get bigger; or any severe or persistent bleeding), swelling of arms or legs, depression, severe loss of strength and energy, weight loss, or shortness of breath (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
