Elementor #13 – Manage advanced prostate and ovarian cancer

INDICATION AND IMPORTANT SAFETY INFORMATION

INDICATION

RUBRACA^® (rucaparib) is indicated for the treatment of adult patients with a deleterious BRCA mutation (germline and/or somatic)-associated metastatic castration-resistant prostate cancer (mCRPC) who have been treated with androgen receptor-directed therapy. Select patients for therapy based on an FDA-approved companion diagnostic for RUBRACA.

SELECT IMPORTANT SAFETY INFORMATION

Myelodysplastic Syndrome (MDS)/Acute Myeloid Leukemia (AML) occur in patients treated with RUBRACA, and are potentially fatal adverse reactions. In 2141 treated patients with ovarian and prostate cancer, MDS/AML occurred in 34 patients (1.6%), including those in long term follow-up. Of these, 14 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 < 2 months to approximately 72 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 DNA damaging agents.

In ARIEL3, of patients with ovarian cancer associated with a germline and/or somatic BRCA mutation who were treated with RUBRACA, MDS/AML occurred in 9 out of 129 (7%) patients treated with RUBRACA and 4 out of 66 (6%) patients treated with placebo. The duration of therapy with RUBRACA in patients who developed secondary MDS/cancer therapy-related AML varied from 1.2 to 4.7 years.

In TRITON3, MDS/AML occurred in 2 out of 201 patients (1%) with a BRCA mutation treated with RUBRACA. The duration of therapy with RUBRACA in patients who developed secondary MDS/cancer therapy-related AML varied from 1.4 to 2.3 years.

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 findings from genetic toxicity and animal reproduction studies, RUBRACA can cause fetal harm. Advise male patients with female partners of reproductive potential or who are pregnant to use effective methods of contraception during treatment and for 3 months following last dose of RUBRACA. Advise male patients not to donate sperm during therapy and for 3 months following the last dose of RUBRACA.

Most common adverse reactions of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON3 (≥10%, Grade 1-4) were fatigue/asthenia (61%), musculoskeletal pain (53%), nausea (51%), decreased appetite (34%), diarrhea (31%), constipation (31%), vomiting (25%), dyspnea (19%), dysgeusia (18%), edema (18%), abdominal pain (17%), dizziness (16%), weight decreased (16%), rash (13%), headache (12%), peripheral neuropathy (12%), photosensitivity reaction (12%), and urinary tract infection (10%).

Most common select laboratory abnormalities of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON3 (≥ 25%, Grade 1-4) were increased ALT (68%), decreased neutrophils (67%), decreased phosphate (64%), decreased hemoglobin (60%), increased AST (59%), increased creatinine (56%), increased glucose (45%), decreased lymphocytes (43%), decreased sodium (35%), decreased platelets (34%), and increased calcium (29%).

Most common adverse reactions of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON2 (≥ 20%; Grade 1-4) were fatigue/asthenia (62%), nausea (52%), decreased appetite (28%), rash (27%), constipation (27%), vomiting (22%), and diarrhea (20%).

Most common laboratory abnormalities of patients with BRCA-mutated mCRPC treated with RUBRACA in TRITON2 (≥ 35%; Grade 1-4) were increased ALT (69%), decreased leukocytes (69%), decreased phosphate (68%), decreased absolute neutrophil count (62%), decreased hemoglobin (59%), increased alkaline phosphatase (44%), increased creatinine (43%), decreased lymphocytes (42%), increased triglycerides (42%), decreased platelets (40%), and decreased sodium (38%).

Concomitant administration of RUBRACA with CYP1A2, CYP3A, CYP2C9, or CYP2C19 substrates can increase the systemic exposure of these substrates, which may increase the frequency or severity of adverse reactions of these substrates. If concomitant administration is unavoidable between RUBRACA and substrates of these enzymes where minimal concentration changes may lead to serious adverse reactions, decrease the substrate dosage in accordance with the approved prescribing information.

If concomitant administration with warfarin (a CYP2C9 substrate) cannot be avoided, consider increasing the frequency of international normalized ratio (INR) monitoring.
