Study Design | Rubraca® (rucaparib) tablets

ARIEL 3 is the first and largest trial in recurrent ovarian cancer to prospectively assess PFS as a primary endpoint in HR-deficient patients1-3

Nearly 2 out of 3 patients enrolled were HR deficient (n=354/564)4,5

Primary endpoint1:

  • PFS by investigator assessment analyzed in 3 prospectively defined molecular subgroups in a step-down manner: 1.) BRCAmut+ patients, 2.) HR deficient patients, and 3.) all randomized patients

Secondary endpoint1,6:

  • PFS by independent radiology review

Predefined exploratory endpoint1:

  • Reduction in tumor burden post–platinum-based chemotherapy

Patients were recruited to reflect a clinically relevant population2,6

Baseline characteristics: pooled for all randomized patients (N=564)1,4

  • Response to most recent platinum-based therapy4
    • 66% partial response
    • 34% complete response
  • Residual tumor burden1,4
    • 37% had measurable disease (investigator-assessed)
    • 18% had bulky disease (>2 cm) (IRR-assessed)
  • BRCA mutation status4
    • 65% were BRCA wild-type
    • 35% were BRCAmut+ (70% germline, 30% somatic)
  • 37% had ≥3 lines of chemotherapy1
  • 22% of patients had received prior bevacizumab1,4

BRCA=breast cancer susceptibility gene; BRCAmut+=BRCA-mutation positive, which includes mutations in the BRCA1 and/or BRCA2 gene; ECOG=Eastern Cooperative Oncology Group; IRR=independent radiology review.

INDICATIONS

Rubraca is indicated:

  • for the maintenance treatment of adult patients with recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in a complete or partial response to platinum-based chemotherapy.

  • for the treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated epithelial ovarian, fallopian tube, or primary peritoneal cancer who have been treated with two or more chemotherapies. Select patients for therapy based on an FDA-approved companion diagnostic for Rubraca.

Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) have occurred in patients treated with Rubraca, and are potentially fatal adverse reactions. In 1146 treated patients, MDS/AML occurred in 20 patients (1.7%), including those in long term follow-up. Of these, 8 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 1 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 regimens and/or other DNA damaging agents.

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 (> 4 weeks), interrupt Rubraca or reduce dose and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks or if MDS/AML is suspected, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Rubraca.

Based on its mechanism of action and findings from animal studies, Rubraca can cause fetal harm when administered to a pregnant woman. Apprise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of Rubraca.

Most common adverse reactions in ARIEL3 (≥ 20%; Grade 1-4) were nausea (76%), fatigue/asthenia (73%), abdominal pain/distention (46%), rash (43%), dysgeusia (40%), anemia (39%), AST/ALT elevation (38%), constipation (37%), vomiting (37%), diarrhea (32%), thrombocytopenia (29%), nasopharyngitis/upper respiratory tract infection (29%), stomatitis (28%), decreased appetite (23%), and neutropenia (20%).

Most common adverse reactions in Study 10 and ARIEL2 (≥ 20%; Grade 1-4) were nausea (77%), asthenia/fatigue (77%), vomiting (46%), anemia (44%), constipation (40%), dysgeusia (39%), decreased appetite (39%), diarrhea (34%), abdominal pain (32%), dyspnea (21%), and thrombocytopenia (21%).

Co-administration of rucaparib can increase the systemic exposure of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, which may increase the risk of toxicities of these drugs. Adjust dosage of CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates, if clinically indicated. If co-administration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing frequency of international normalized ratio (INR) monitoring.

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 2 weeks after the last dose.
