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

• Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in approximately 1.2% of patients with various BRCA m, g BRCA m, HRR gene-mutated or HRD-positive cancers exposed to Lynparza and the majority of events had a fatal outcome. Monitor patients for hematological toxicity at baseline and monthly thereafter. Discontinue if MDS/AML is confirmed. • Pneumonitis: Occurred in 1.0% of patients exposed to Lynparza, and some cases were fatal. Interrupt treatment if pneumonitis is suspected. Discontinue if pneumonitis is confirmed. • Venous thromboembolism (VTE), including severe or fatal pulmonary embolism (PE), occurred in patients treated with Lynparza. VTE occurred in 8% of patients with mCRPC. Monitor patients for signs and symptoms of VTE and PE and treat as medically appropriate. • Hepatotoxicity, Including Drug-induced liver injury (DILI): Occurred in patients treated with Lynparza. If DILI is suspected, interrupt Lynparza. If DILI is confirmed, discontinue treatment. • Embryo-Fetal Toxicity: Can cause fetal harm. Advise of the potential risk to a fetus and to use effective contraception. ( 5.5 , 8.1 , 8.3 ) 5.1 Myelodysplastic 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 BRCA m, g BRCA m, 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) . 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. In SOLO1, patients with newly diagnosed advanced BRCA m ovarian cancer, the incidence of MDS/AML was 1.9% (5/260) in patients who received Lynparza and 0.8% (1/130) in patients who received placebo based on an updated analysis. In PAOLA-1, of patients with newly diagnosed advanced ovarian cancer with HRD-positive status, the incidence of MDS/AML was 1.6% (4/255) in patients who received Lynparza and 2.3% (3/131) in the control arm. In SOLO2, patients with BRCA m platinum-sensitive relapsed ovarian cancer, the incidence of MDS/AML was 8% (15/195) in patients who received Lynparza and 4% (4/99) in patients who received placebo. The duration of Lynparza treatment prior to the diagnosis of MDS/AML ranged from 0.6 years to 4.5 years. 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

Pneumonitis 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 , 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 . 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 . 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 .

• Strong or moderate CYP3A inhibitors: Avoid concomitant use. If concomitant use cannot be avoided, reduce Lynparza dosage. ( 2.4 , 7.2 , 12.3 ) • Strong or moderate CYP3A inducers: Avoid concomitant use. ( 7.2 , 12.3 ) 7.1 Use with Anticancer Agents Clinical studies of Lynparza with other myelosuppressive anticancer agents, including DNA damaging agents, indicate a potentiation and prolongation of myelosuppressive toxicity

Effect of Other Drugs on Lynparza Strong and Moderate CYP3A Inhibitors Coadministration of CYP3A inhibitors can increase olaparib concentrations, which may increase the risk for adverse reactions . Avoid coadministration of strong or moderate CYP3A inhibitors. If the strong or moderate inhibitor must be coadministered, reduce the dose of Lynparza . Strong and Moderate CYP3A Inducers Concomitant use with a strong or moderate CYP3A inducer decreased olaparib exposure, which may reduce Lynparza efficacy . Avoid coadministration of strong or moderate CYP3A inducers.
