Merck Lynparza page 3 of 5 4C LYNPARZA® (olaparib) tablets, for oral use Initial U.S. Approval: 2014 Brief Summary of Prescribing Information. For complete prescribing information consult official package insert. INDIC ATIONS AND USAGE HRR Gene-mutated Metastatic Castration-Resistant Prostate Cancer Lynparza is indicated for the treatment of adult patients with deleterious or suspected deleterious germline or somatic homologous recombination repair (HRR) gene-mutated metastatic castration-resistant prostate cancer (mCRPC) who have progressed following prior treatment with enzalutamide or abiraterone. Select patients for therapy based on an FDA-approved companion diagnostic for Lynparza [see Dosage and Administration (2.1) in the full Prescribing Information]. Treatment of BRCA-mutated Metastatic Castration-Resistant Prostate Cancer in Combination with Abiraterone and Prednisone or Prednisolone Lynparza is indicated in combination with abiraterone and prednisone or prednisolone for the treatment of adult patients with deleterious or suspected deleterious BRCA-mutated (BRCAm) metastatic castration-resistant prostate cancer (mCRPC). Select patients for therapy based on an FDA-approved companion diagnostic for Lynparza [see Dosage and Administration (2.1) in the full Prescribing Information]. DOSAGE AND ADMINISTRATION Patient Selection Information on FDA-approved tests for the detection of genetic mutations is available at http://www.fda.gov/companiondiagnostics. Select patients for treatment with Lynparza based on the presence of deleterious or suspected deleterious HRR gene mutations, including BRCA mutations, or genomic instability based on the indication, biomarker, and sample type (Table 1). Table 1 Biomarker Testing for Patient Selection* Indication Biomarker Sample type Tumor Blood Plasma (ctDNA) Germline or somatic HRR gene-mutated metastatic castration-resistant prostate cancer ATMm, BRCA1m, BRCA2m, BARD1m, BRIP1m, CDK12m, CHEK1m, CHEK2m, FANCLm, PALB2m, RAD51Bm, RAD51Cm, RAD51Dm, RAD54Lm X gBRCA1m, gBRCA2m X ATMm, BRCA1m, BRCA2m X BRCA-mutated metastatic castration-resistant prostate cancer in combination with abiraterone and prednisone or prednisolone BRCA1m, BRCA2m X X X * Where testing fails or tissue sample is unavailable/insufficient, or when germline testing is negative, consider using an alternative test, if available. Recommended Dosage The recommended dosage of Lynparza is 300 mg taken orally twice daily, with or without food. If a patient misses a dose of Lynparza, instruct patient to take their next dose at its scheduled time. Instruct patients to swallow tablets whole. Do not chew, crush, dissolve, or divide tablet. HRR Gene-mutated Metastatic Castration-Resistant Prostate Cancer Continue treatment until disease progression or unacceptable toxicity for: • HRR gene-mutated metastatic castration-resistant prostate cancer. BRCA-mutated Metastatic Castration-Resistant Prostate Cancer in Combination with Abiraterone and Prednisone or Prednisolone Continue treatment until disease progression or unacceptable toxicity. When used with Lynparza, the recommended dose of abiraterone is 1000 mg taken orally once daily. Abiraterone should be given in combination with prednisone or prednisolone 5 mg orally twice daily. Refer to the Prescribing Information for abiraterone for dosing information. Patients with mCRPC should also receive a gonadotropin-releasing hormone (GnRH) analog concurrently or should have had bilateral orchiectomy. Dosage Modifications for Adverse Reactions To manage adverse reactions, consider interruption of treatment or dose reduction. The recommended dose reduction is 250 mg taken twice daily. If a further dose reduction is required, then reduce to 200 mg taken twice daily. Dosage Modifications for Concomitant Use with Strong or Moderate CYP3A Inhibitors Avoid concomitant use of strong or moderate CYP3A inhibitors with Lynparza. If concomitant use cannot be avoided, reduce Lynparza dosage to: • 100 mg twice daily when used concomitantly with a strong CYP3A inhibitor. • 150 mg twice daily when used concomitantly with a moderate CYP3A inhibitor. After the inhibitor has been discontinued for 3 to 5 elimination half-lives, resume the Lynparza dose taken prior to initiating the CYP3A inhibitor [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) in the full Prescribing Information]. Dosage Modifications for Renal Impairment Moderate Renal Impairment In patients with moderate renal impairment (CLcr 31-50 mL/min), reduce the Lynparza dosage to 200 mg orally twice daily [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) in the full Prescribing Information]. CONTRAINDICATIONS None. WARNINGS AND PRECAUTIONS Myel odysplastic Syndrome/Acute Myeloid Leukemia Myelodysplastic syndrome (MDS)/Acute Myeloid Leukemia (AML) has occurred in patients treated with Lynparza and some cases were fatal. In clinical studies, among 2219 patients with various BRCAm, gBRCAm, HRR gene-mutated or HRD-positive cancers who received Lynparza as a single agent or as part of combination regimen, consistent with approved indications, the cumulative incidence of MDS/AML was approximately 1.2% (26/2219) [see Adverse Reactions (6.1) in the full Prescribing Information]. Of these, 54% (14/26) had a fatal outcome. The median duration of therapy with Lynparza in patients who developed MDS/AML was approximately 2 years (range: < 6 months to > 4 years). All of these patients had received previous chemotherapy with platinum agents and/or other DNA damaging agents including radiotherapy. Do not start Lynparza until patients have recovered from hematological toxicity caused by previous chemotherapy (≤ Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt Lynparza and monitor blood counts weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue Lynparza. Pneu monitis Pneumonitis, including severe and fatal cases, has occurred in patients treated with Lynparza. In clinical studies, among patients who received Lynparza as a single agent or as part of a combination regimen [see Adverse Reactions (6.1) in the full Prescribing Information], the incidence of pneumonitis, including fatal cases, was 1.0% (29/2851). If patients present with new or worsening respiratory symptoms such as dyspnea, cough and fever, or a radiological abnormality occurs, interrupt Lynparza treatment and promptly assess the source of the symptoms. If pneumonitis is confirmed, discontinue Lynparza treatment and treat the patient appropriately. Venous Thromboembolism Venous thromboembolism (VTE), including severe or fatal pulmonary embolism (PE), occurred in patients treated with Lynparza [see Adverse Reactions (6.1) in the full Prescribing Information]. In the combined data of two randomized, placebo-controlled clinical studies (PROfound and PROpel) in patients with metastatic castration-resistant prostate cancer (N=1180), VTE occurred in 8% of patients who received Lynparza, including pulmonary embolism in 6%. In the control arms, VTE occurred in 2.5% including pulmonary embolism in 1.5%. Monitor patients for clinical signs and symptoms of venous thrombosis and pulmonary embolism and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated. Hepatotoxicity, Including Drug-Induced Liver Injury Hepatotoxicity, including severe and potentially fatal cases of drug-induced liver injury (DILI), has occurred in patients treated with Lynparza [see Adverse Reactions (6.2) in the full Prescribing Information]. Evaluate bilirubin and transaminases at baseline and throughout treatment with Lynparza. For patients who develop abnormal liver tests after Lynparza, monitor more frequently for liver test abnormalities and clinical signs and symptoms of hepatic toxicity. If DILI is suspected, withhold Lynparza. Upon confirmation of DILI, discontinue Lynparza. Embryo-Fetal Toxicity Lynparza can cause fetal harm when administered to a pregnant woman based on its mechanism of action and findings in animals. In an animal reproduction study, administration of olaparib to pregnant rats during the period of organogenesis caused teratogenicity and embryo-fetal toxicity at exposures below those in patients receiving the recommended human dose of 300 mg twice daily. Apprise pregnant women of the potential hazard to a fetus and the potential risk for loss of the pregnancy. Advise females of reproductive potential to use effective contraception during treatment and for 6 months following the last dose of Lynparza. Based on findings from genetic toxicity and animal reproduction studies, advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of Lynparza [see Use in Specific Populations (8.1, 8.3) in the full Prescribing Information]. ADVERSE REACTIONS The following adverse reactions are discussed elsewhere in the labeling: • Myelodysplastic Syndrome/Acute Myeloid Leukemia [see Warnings and Precautions (5.1) in the full Prescribing Information] • Pneumonitis [see Warnings and Precautions (5.2) in the full Prescribing Information] • Venous Thromboembolism [see Warnings and Precautions (5.3) in the full Prescribing Information] • Hepatotoxicity, Including Drug-Induced Liver Injury [see Warnings and Precautions (5.4) in the full Prescribing Information]
