1 INDICATIONS AND USAGE VENCLEXTA is a BCL-2 inhibitor indicated: For the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). ( 1.1 ) In combination with azacitidine, or decitabine, or low-dose cytarabine for the treatment of newly diagnosed acute myeloid leukemia (AML) in adults 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy. ( 1.2 ) 1.1 Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma VENCLEXTA is indicated for the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). 1.2 Acute Myeloid Leukemia VENCLEXTA is indicated in combination with azacitidine, or decitabine, or low-dose cytarabine for the treatment of newly diagnosed acute myeloid leukemia (AML) in adults 75 years or older, or who have comorbidities that preclude use of intensive induction chemotherapy.

2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for recommended VENCLEXTA dosages. ( 2.2 , 2.3 ) Take VENCLEXTA tablets orally once daily with a meal and water. ( 2.8 ) Provide prophylaxis for tumor lysis syndrome. ( 2.1 , 2.4 ) 2.1 Important Safety Information Assess patient-specific factors for level of risk of tumor lysis syndrome (TLS) and provide prophylactic hydration and anti-hyperuricemics to patients prior to first dose of VENCLEXTA to reduce risk of TLS [see Dosage and Administration ( 2.4 ) and Warnings and Precautions ( 5.1 )]. 2.2 Recommended Dosage for Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma VENCLEXTA dosing begins with a 5-week ramp-up. The 5-week ramp-up dosing schedule is designed to gradually reduce tumor burden (debulk) and decrease the risk of TLS. VENCLEXTA 5-week Dose Ramp-Up Schedule Administer VENCLEXTA according to the 5-week ramp-up dosing schedule to the recommended dosage of 400 mg orally once daily as shown in Table 1 . Table 1. Dosing Schedule for 5-Week Ramp-up Phase for Patients with CLL/SLL VENCLEXTA Oral Daily Dose Week 1 20 mg Week 2 50 mg Week 3 100 mg Week 4 200 mg Week 5 and beyond 400 mg The CLL/SLL Starting Pack provides the first 4 weeks of VENCLEXTA according to the ramp-up schedule [see How Supplied/Storage and Handling ( 16 )] . In Combination with Acalabrutinib Cycle 1 Day 1: Start acalabrutinib 100 mg orally approximately every 12 hours until disease progression, unacceptable toxicity or completion of 14 cycles of treatment. Each cycle is 28 days. Refer to the acalabrutinib prescribing information for additional dosing information. Cycle 3 Day 1: start VENCLEXTA according to the 5-week ramp-up dosing schedule (see Table 1 ). After completing the ramp-up phase, continue VENCLEXTA at a dose of 400 mg orally once daily until disease progression, unacceptable toxicity, or until the last day of Cycle 14. In Combination with Obinutuzumab Start obinutuzumab administration at 100 mg on Cycle 1 Day…

12.2 Pharmacodynamics Based on the exposure response analyses for efficacy, a relationship between drug exposure and a greater likelihood of response was observed in clinical studies in patients with CLL/SLL, and in patients with AML. Based on the exposure response analyses for safety, a relationship between drug exposure and a greater likelihood of some safety events was observed in clinical studies in patients with AML. No exposure-safety relationship was observed in patients with CLL/SLL at doses up to 1200 mg given as monotherapy and up to 600 mg given in combination with rituximab. Cardiac Electrophysiology The effect of multiple doses of VENCLEXTA up to 1200 mg once daily (2 times the maximum approved recommended dosage) on the QTc interval was evaluated in an open-label, single-arm trial in 176 patients with previously treated hematologic malignancies. VENCLEXTA had no large effect on QTc interval (i.e., >20 ms) and there was no relationship between venetoclax exposure and change in QTc interval.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Tumor Lysis Syndrome [see Warnings and Precautions ( 5.1 )] Neutropenia [see Warnings and Precautions ( 5.2 )] Infections [see Warnings and Precautions ( 5.3 )] In CLL/SLL, the most common adverse reactions (≥20%) for VENCLEXTA when given in combination with obinutuzumab or rituximab or as monotherapy are neutropenia, thrombocytopenia, anemia, diarrhea, nausea, upper respiratory tract infection, cough, musculoskeletal pain, fatigue, and edema. ( 6.1 ) In CLL/SLL, the most common adverse reactions (≥20%) for VENCLEXTA when given in combination with acalabrutinib are neutropenia, headache, diarrhea, musculoskeletal pain, and COVID-19. ( 6.1 ) In AML, the most common adverse reactions (≥30%) in combination with azacitidine or decitabine or low-dose cytarabine are nausea, diarrhea, thrombocytopenia, constipation, neutropenia, febrile neutropenia, fatigue, vomiting, edema, pyrexia, pneumonia, dyspnea, hemorrhage, anemia, rash, abdominal pain, sepsis, musculoskeletal pain, dizziness, cough, oropharyngeal pain, and hypotension.

In CLL/SLL, the safety population reflects exposure to VENCLEXTA as monotherapy in patients in M13-982, M14-032, and M12-175 and in combination with obinutuzumab or rituximab in patients in CLL14 and MURANO. In this CLL/SLL safety population, the most common adverse reactions (≥20%) for VENCLEXTA were neutropenia, thrombocytopenia, anemia, diarrhea, nausea, upper respiratory tract infection, cough, musculoskeletal pain,…

4 CONTRAINDICATIONS Concomitant use of VENCLEXTA with strong CYP3A inhibitors at initiation and during the ramp-up phase is contraindicated in patients with CLL/SLL due to the potential for increased risk of tumor lysis syndrome [see Dosage and Administration ( 2.6 ) and Drug Interactions ( 7.1 )] . Concomitant use with strong CYP3A inhibitors at initiation and during ramp-up phase in patients with CLL/SLL is contraindicated. ( 2.6 , 4 , 7.1 )

5 WARNINGS AND PRECAUTIONS Tumor Lysis Syndrome (TLS): Anticipate TLS; assess risk in all patients. Premedicate with anti-hyperuricemics and ensure adequate hydration. Employ more intensive measures (intravenous hydration, frequent monitoring, hospitalization) as overall risk increases. ( 2.4 , 5.1 ) Neutropenia: Monitor blood counts. Interrupt dosing and resume at same or reduced dose. Consider supportive care measures. ( 2.5 , 5.2 ) Infections: Monitor for signs and symptoms of infection and treat promptly. Withhold for Grade 3 and 4 infection until resolution and resume at same or reduced dose. ( 2.5 , 5.3 ) Immunization: Do not administer live attenuated vaccines prior to, during, or after treatment with VENCLEXTA until B-cell recovery. ( 5.4 ) Embryo-Fetal Toxicity: May cause embryo-fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. ( 5.5 ) Treatment of patients with multiple myeloma with VENCLEXTA in combination with bortezomib plus dexamethasone is not recommended outside of controlled clinical trials. ( 5.6 ) 5.1 Tumor Lysis Syndrome Tumor lysis syndrome (TLS), including fatal events and renal failure requiring dialysis, has occurred in patients treated with VENCLEXTA [see Adverse Reactions ( 6.1 )]. VENCLEXTA can cause rapid reduction in tumor and thus poses a risk for TLS at initiation and during the ramp-up phase in all patients, and during reinitiation after dosage interruption in patients with CLL/SLL. Changes in blood chemistries consistent with TLS that require prompt management can occur as early as 6 to 8 hours following the first dose of VENCLEXTA and at each dose increase. TLS, including fatal cases, has been reported after a single 20 mg dose of VENCLEXTA. In patients with CLL/SLL who followed the current (5-week) dose ramp-up and the TLS prophylaxis and monitoring measures, the rate of TLS was 2% in the VENCLEXTA CLL/SLL monotherapy trials. The rate of TLS remained…

7 DRUG INTERACTIONS Strong or moderate CYP3A inhibitors or P-gp inhibitors: Adjust dosage of VENCLEXTA. ( 2.6 , 7.1 ) Strong or moderate CYP3A inducers: Avoid co-administration. ( 7.1 ) P-gp substrates: Take at least 6 hours before VENCLEXTA. ( 7.2 ) 7.1 Effects of Other Drugs on VENCLEXTA Strong or Moderate CYP3A Inhibitors or P-gp Inhibitors Concomitant use with a strong or moderate CYP3A inhibitor or a P-gp inhibitor increases venetoclax C max and AUC 0-INF [see Clinical Pharmacology ( 12.3 )] , which may increase VENCLEXTA toxicities, including the risk of TLS [see Warnings and Precautions ( 5.1 )] . Concomitant use with a strong CYP3A inhibitor at initiation and during the ramp-up phase in patients with CLL/SLL is contraindicated [see Contraindications ( 4 )] . In patients with CLL/SLL taking a steady daily dosage (after ramp-up phase), consider alternative medications or adjust VENCLEXTA dosage and monitor more frequently for adverse reactions [see Dosage and Administration ( 2.5 , 2.6 )] . In patients with AML, adjust VENCLEXTA dosage and monitor more frequently for adverse reactions [see Dosage and Administration ( 2.5 , 2.6 )] . Resume the VENCLEXTA dosage that was used prior to concomitant use with a strong or moderate CYP3A inhibitor or a P-gp inhibitor 2 to 3 days after discontinuation of the inhibitor [see Dosage and Administration ( 2.5 , 2.6 )] . Avoid grapefruit products, Seville oranges, and starfruit during treatment with VENCLEXTA, as they contain inhibitors of CYP3A. Strong or Moderate CYP3A Inducers Concomitant use with a strong CYP3A inducer decreases venetoclax C max and AUC 0-INF [see Clinical Pharmacology ( 12.3 )] , which may decrease VENCLEXTA efficacy. Avoid concomitant use of VENCLEXTA with strong CYP3A inducers or moderate CYP3A inducers. 7.2 Effect of VENCLEXTA on Other Drugs Warfarin Concomitant use of VENCLEXTA increases warfarin C max and AUC 0-INF [see Clinical Pharmacology ( 12.3 )] , which may increase the risk of bleeding.…
