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.
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 1, followed by 900 mg on Cycle 1 Day 2. Administer 1,000 mg on Days 8 and 15 of Cycle 1 and on Day 1 of each subsequent 28-day cycle for a total of 6 cycles. Refer to the obinutuzumab prescribing information for additional dosing information. On Cycle 1 Day 22, start VENCLEXTA according to the 5-week ramp-up dosing schedule (see Table 1 ). After completing the ramp-up phase on Cycle 2 Day 28, continue VENCLEXTA at a dose of 400 mg orally once daily from Cycle 3 Day 1 until the last day of Cycle 12. In Combination with Rituximab Start rituximab administration after the patient has completed the 5-week ramp-up dosing schedule for VENCLEXTA (see Table 1 ) and has received VENCLEXTA at the recommended dosage of 400 mg orally once daily for 7 days. Administer rituximab on Day 1 of each 28-day cycle for 6 cycles, at a dose of 375 mg/m 2 intravenously for Cycle 1 and 500 mg/m 2 intravenously for Cycles 2-6. Continue VENCLEXTA 400 mg orally once daily for 24 months from Cycle 1 Day 1 of rituximab. Refer to the rituximab prescribing information for additional dosing information. Monotherapy The recommended dosage of VENCLEXTA is 400 mg once daily after completion of the 5-week ramp-up dosing schedule (see Table 1 ). Continue VENCLEXTA until disease progression or unacceptable toxicity.
2.3 Recommended Dosage for Acute Myeloid Leukemia The recommended dosage and ramp-up of VENCLEXTA depends upon the combination agent. Follow the dosing schedule, including the 3-day or 4-day dose ramp-up, as shown in Table 2. Start VENCLEXTA administration on Cycle 1 Day 1 in combination with: Azacitidine 75 mg/m 2 intravenously or subcutaneously once daily on Days 1-7 of each 28-day cycle; OR Decitabine 20 mg/m 2 intravenously once daily on Days 1-5 of each 28-day cycle; OR Cytarabine 20 mg/m 2 subcutaneously once daily on Days 1-10 of each 28-day cycle. Table 2. Dosing Schedule for 3- or 4-Day Ramp-up Phase in Patients with AML VENCLEXTA Oral Daily Dose Day 1 100 mg Day 2 200 mg Day 3 400 mg Days 4 and beyond 400 mg orally once daily of each 28-day cycle in combination with azacitidine or decitabine 600 mg orally once daily of each 28-day cycle in combination with low-dose cytarabine Continue VENCLEXTA, in combination with azacitidine or decitabine or low-dose cytarabine, until disease progression or unacceptable toxicity. Refer to Clinical Studies ( 14.2 ) and Prescribing Information for azacitidine, decitabine, or cytarabine for additional dosing information.
2.4 Risk Assessment and Prophylaxis for Tumor Lysis Syndrome Patients treated with VENCLEXTA may develop tumor lysis syndrome (TLS). Refer to the appropriate section below for specific details on management. Assess patient-specific factors for level of risk of TLS and provide prophylactic hydration and anti-hyperuricemics to patients prior to first dose of VENCLEXTA to reduce risk of TLS. Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma VENCLEXTA can cause rapid reduction in tumor and thus poses a risk for TLS in the initial 5-week ramp-up phase. 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 can also occur upon resumption of VENCLEXTA following a dosage interruption. See Table 4 , Table 5 , and Table 6 for dose modifications of VENCLEXTA after interruption. The risk of TLS is a continuum based on multiple factors, particularly reduced renal function (creatinine clearance [CLcr] <80 mL/min) and tumor burden; splenomegaly may also increase the risk of TLS. Perform tumor burden assessments, including radiographic evaluation (e.g., CT scan), assess blood chemistry (potassium, uric acid, phosphorus, calcium, and creatinine) in all patients and correct pre-existing abnormalities prior to initiation of treatment with VENCLEXTA. The risk may decrease as tumor burden decreases [see Warnings and Precautions ( 5.1 ) and Use in Specific Populations ( 8.6 )] . Table 3 below describes the recommended TLS prophylaxis and monitoring during VENCLEXTA treatment based on tumor burden determination from clinical trial data. Consider all patient comorbidities before final determination of prophylaxis and monitoring schedule. Reassess the risk of TLS when reinitiating VENCLEXTA after a dosage interruption lasting more than 1 week during the ramp-up phase, or more than 2 weeks after completion of ramp-up. Institute prophylaxis and monitoring as needed. Table 3.

Acute Myeloid Leukemia All patients should have white blood cell count less than 25 × 10 9 /L prior to initiation of VENCLEXTA. Cytoreduction prior to treatment may be required. Prior to first VENCLEXTA dose, provide all patients with prophylactic measures including adequate hydration and anti-hyperuricemic agents and continue during ramp-up phase. Assess blood chemistry (potassium, uric acid, phosphorus, calcium, and creatinine) and correct pre-existing abnormalities prior to initiation of treatment with VENCLEXTA. Monitor blood chemistries for TLS at pre-dose, 6 to 8 hours after each new dose during ramp-up, and 24 hours after reaching final dose. For patients with risk factors for TLS (e.g., circulating blasts, high burden of leukemia involvement in bone marrow, elevated pretreatment lactate dehydrogenase [LDH] levels, or reduced renal function), consider additional measures, including increased laboratory monitoring and reducing VENCLEXTA starting dose.
2.5 Dosage Modifications for Adverse Reactions Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma The recommended dose reductions for VENCLEXTA for adverse reactions are provided in Table 4 . The recommended dosage modifications for VENCLEXTA for adverse reactions are provided in Table 5 and Table 6 . For patients having a dosage interruption lasting more than 1 week during the ramp-up phase, or more than 2 weeks after completion of ramp-up, reassess for risk of TLS to determine if reinitiation with a reduced dose is necessary (e.g., all or some levels of the dose ramp-up schedule) [see Dosage and Administration ( 2.2 , 2.4 )].

2.6 Dosage Modifications for Drug Interactions Strong or Moderate CYP3A Inhibitors or P-gp Inhibitors Table 8 describes VENCLEXTA contraindication or dosage modification based on concomitant use with a strong or moderate CYP3A inhibitor or a P-gp inhibitor [see Drug Interactions ( 7.1 )] at initiation, during, or after the ramp-up phase. Resume the VENCLEXTA dosage that was used prior to concomitant use of a strong or moderate CYP3A inhibitor or a P-gp inhibitor 2 to 3 days after discontinuation of the inhibitor [see Drug Interactions ( 7.1 )] . Table 8. Management of Potential VENCLEXTA Interactions with CYP3A and P-gp Inhibitors Coadministered Drug Initiation and Ramp-Up Phase Steady Daily Dose (After Ramp-Up Phase) a Posaconazole CLL/SLL Contraindicated Reduce VENCLEXTA dose to 70 mg. AML Day 1 – 10 mg Day 2 – 20 mg Day 3 – 50 mg Day 4 – 70 mg Other strong CYP3A inhibitor CLL/SLL Contraindicated Reduce VENCLEXTA dose to 100 mg. AML Day 1 – 10 mg Day 2 – 20 mg Day 3 – 50 mg Day 4 – 100 mg Moderate CYP3A inhibitor Reduce the VENCLEXTA dose by at least 50%. P-gp inhibitor a In patients with CLL/SLL, consider alternative medications or reduce the VENCLEXTA dose as described in Table 8 .
2.7 Dosage Modifications for Patients with Severe Hepatic Impairment Reduce the VENCLEXTA once daily dose by 50% for patients with severe hepatic impairment (Child-Pugh C); monitor these patients more closely for adverse reactions [see Use in Specific Populations ( 8.7 )] .
2.8 Administration Instruct patients of the following: Take VENCLEXTA with a meal and water. Take VENCLEXTA at approximately the same time each day. The recommended dosage of VENCLEXTA may be delivered using any of the approved tablet strengths. For patients who are unable to swallow a VENCLEXTA tablet whole, the tablets can be crushed [see Clinical Pharmacology ( 12.3 )] . Mix the entire dose with 120 mL (4 ounces) of water, apple juice, apple sauce, or yogurt. Take the entire dose immediately with a meal and water. Do not crush more than one dose at a time. If the patient misses a dose of VENCLEXTA within 8 hours of the time it is usually taken, instruct the patient to take the missed dose as soon as possible and resume the normal daily dosing schedule. If a patient misses a dose by more than 8 hours, instruct the patient not to take the missed dose and resume the usual dosing schedule the next day. If the patient vomits following dosing, instruct the patient to not take an additional dose that day and to take the next prescribed dose at the usual time.

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 )
Warnings and precautions
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 consistent with VENCLEXTA in combination with obinutuzumab or rituximab. With a 2- to 3-week dose ramp-up and higher starting dose in patients with CLL/SLL, the TLS rate was 13% and included deaths and renal failure [see Adverse Reactions ( 6.1 )] . In patients with AML who followed the current 3-day ramp-up dosing schedule and the TLS prophylaxis and monitoring measures, the rate of TLS was 1.1% in patients who received VENCLEXTA in combination with azacitidine (VIALE-A). In patients with AML who followed a 4-day ramp-up dosing schedule and the TLS prophylaxis and monitoring measures, the rate of TLS was 5.6% and included deaths and renal failure in patients who received VENCLEXTA in combination with low-dose cytarabine (VIALE-C) [see Adverse Reactions ( 6.1 )]. The risk of TLS is a continuum based on multiple factors, particularly reduced renal function, tumor burden, and type of malignancy. Splenomegaly may also increase the risk of TLS in patients with CLL/SLL. Assess all patients for risk and provide appropriate prophylaxis for TLS, including hydration and anti-hyperuricemics. Monitor blood chemistries and manage abnormalities promptly. Employ more intensive measures (intravenous hydration, frequent monitoring, hospitalization) as overall risk increases. Interrupt dosing if needed; when restarting VENCLEXTA, follow dose modification guidance [see Dosage and Administration ( 2.1 , 2.2 , 2.3 , 2.4 ) and Use in Specific Populations ( 8.6 )]. Concomitant use of VENCLEXTA with P-gp inhibitors or strong or moderate CYP3A inhibitors increases venetoclax exposure, which may increase the risk of TLS at initiation and during the ramp-up phase of VENCLEXTA. For patients with CLL/SLL, coadministration of VENCLEXTA with strong CYP3A inhibitors at initiation and during the 5-week ramp-up phase is contraindicated [see Contraindications ( 4 )]. For patients with AML, reduce the dose of VENCLEXTA when coadministered with strong CYP3A inhibitors at initiation and during the 3- or 4-day ramp-up phase. For patients with CLL/SLL or AML, reduce the dose of VENCLEXTA when coadministered with moderate CYP3A4 inhibitors or P-gp inhibitors [see Dosage and Administration ( 2.6 ) and Drug Interactions ( 7.1 )].
5.2 Neutropenia In patients with CLL, Grade 3 or 4 neutropenia developed in 63% to 64% of patients and Grade 4 neutropenia developed in 31% to 33% of patients when treated with VENCLEXTA in monotherapy studies and in combination studies with obinutuzumab or rituximab. Febrile neutropenia occurred in 4% to 6% of patients treated with VENCLEXTA in monotherapy studies and in combination studies with obinutuzumab or rituximab [see Adverse Reactions ( 6.1 )] . In patients with CLL, Grade 3 or 4 neutropenia developed in 38% of patients and Grade 4 neutropenia developed in 15% of patients when treated with VENCLEXTA in combination with acalabrutinib. Febrile neutropenia occurred in 2% of patients treated with VENCLEXTA in combination with acalabrutinib [see Adverse Reactions ( 6.1 )] . In patients with AML, baseline neutrophil counts worsened in 95% to 100% of patients treated with VENCLEXTA in combination with azacitidine, decitabine, or low-dose cytarabine. Neutropenia can recur with subsequent cycles. Monitor complete blood counts throughout the treatment period. For interruption and dose resumption of VENCLEXTA for severe neutropenia, see Table 5 and Table 6 for CLL and Table 7 for AML [see Dosage and Administration ( 2.5 )]. Consider supportive measures, including antimicrobials and growth factors (e.g., G-CSF).
5.3 Infections Fatal and serious infections, such as pneumonia and sepsis, have occurred in patients treated with VENCLEXTA [see Adverse Reactions ( 6.1 )] . Monitor patients for signs and symptoms of infection and treat promptly. Withhold VENCLEXTA for Grade 3 and 4 infection until resolution. For dose resumptions, see Table 5 and Table 6 for CLL and Table 7 for AML [see Dosage and Administration ( 2.5 )] . In AMPLIFY, a randomized study in patients with previously untreated CLL/SLL, serious or grade 3 or higher infections occurred in 14% of patients who received VENCLEXTA in combination with acalabrutinib (VEN+A), most commonly due to COVID-19. In an additional cohort of patients receiving VENCLEXTA in combination with acalabrutinib and obinutuzumab (AVO) (an unapproved regimen for previously untreated CLL/SLL in AMPLIFY), serious or Grade 3 or higher infections occurred in 25% receiving AVO compared to 14% in patients receiving VEN+A. Fatal infections occurred in 6% receiving AVO compared to 3.1% of patients receiving VEN+A, most commonly due to COVID-19. The safety and effectiveness of AVO has not been established in patients with previously untreated CLL/SLL [see Clinical Studies ( 14.1 )] .
5.4 Immunization Do not administer live attenuated vaccines prior to, during, or after treatment with VENCLEXTA until B-cell recovery occurs. The safety and efficacy of immunization with live attenuated vaccines during or following VENCLEXTA therapy have not been studied. Advise patients that vaccinations may be less effective.
5.5 Embryo-Fetal Toxicity Based on findings in animals and its mechanism of action, VENCLEXTA may cause embryo-fetal harm when administered to a pregnant woman. In an embryo-fetal study conducted in mice, administration of venetoclax to pregnant animals at exposures equivalent to that observed in patients at a dose of 400 mg daily resulted in post-implantation loss and decreased fetal weight. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with VENCLEXTA and for 30 days after the last dose [see Use in Specific Populations ( 8.1 , 8.3 )] .
5.6 Increased Mortality in Patients with Multiple Myeloma when VENCLEXTA is Added to Bortezomib and Dexamethasone In a randomized trial (BELLINI; NCT02755597) in patients with relapsed or refractory multiple myeloma, the addition of VENCLEXTA to bortezomib plus dexamethasone, a use for which VENCLEXTA is not indicated, resulted in increased mortality. Treatment of patients with multiple myeloma with VENCLEXTA in combination with bortezomib plus dexamethasone is not recommended outside of controlled clinical trials.
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. Monitor international normalized ratio (INR) more frequently in patients using warfarin concomitantly with VENCLEXTA. P-gp Substrates Concomitant use of VENCLEXTA increases C max and AUC 0-INF of P-gp substrates [see Clinical Pharmacology ( 12.3 )] , which may increase toxicities of these substrates. Avoid concomitant use of VENCLEXTA with a P-gp substrate. If a concomitant use is unavoidable, separate dosing of the P-gp substrate at least 6 hours before VENCLEXTA.

6.1 Clinical Trials Experience Because clinical trials are conducted under widely variable conditions, adverse event rates observed in clinical trials of a drug cannot be directly compared with rates of clinical trials of another drug and may not reflect the rates observed in practice. 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, fatigue, and edema. In the CLL/SLL safety population that reflects exposure to VENCLEXTA in combination with acalabrutinib, the most common adverse reactions (≥20%) were neutropenia, headache, diarrhea, musculoskeletal pain, and COVID-19. In AML, the safety population reflects exposure to VENCLEXTA in combination with decitabine, azacitidine, or low-dose cytarabine in patients in M14-358, VIALE-A, and VIALE-C. In this safety population, the most common adverse reactions (≥30% in any trial) were 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. Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma VENCLEXTA in Combination with Acalabrutinib The safety of VENCLEXTA in combination with acalabrutinib (VEN+A) (N=291) versus fludarabine plus cyclophosphamide plus rituximab or bendamustine plus rituximab (FCR/BR) (N=259) was evaluated in AMPLIFY, a randomized, multicenter, open-label study in patients with previously untreated CLL [ see Clinical S tudies ( 14.1 ) ] . The median duration of exposure to VENCLEXTA was 11.1 months (range: 2 to 14 months) and to acalabrutinib was 12.9 months (range: 1 to 18 months) in the VEN+A arm. Among patients who received VEN+A, 96% were exposed for 6 months or longer and 91% were exposed for greater than one year. Serious adverse reactions were reported in 25% of patients receiving VEN+A. The most common adverse reaction (≥2%) were COVID-19 including COVID-19 pneumonia (9%), second primary malignancies (2.7%), and neutropenia (2.1%). Fatal adverse events occurred in 3.4% of patients. The most common fatal adverse events included COVID-19 and COVID-19 pneumonia. In the VEN+A arm, adverse reactions led to treatment discontinuation in 8% of patients. Neutropenia led to discontinuation of VENCLEXTA in 0.3% of patients, dose reduction in 7%, and dose interruption in 21%. Table 10 presents adverse reactions identified in AMPLIFY. Table 10.

VENCLEXTA in Combination with Obinutuzumab The safety of VENCLEXTA in combination with obinutuzumab (VEN+G) (N=212) versus obinutuzumab in combination with chlorambucil (GClb) (N=214) was evaluated in CLL14, a randomized, open-label, actively controlled trial in patients with previously untreated CLL [see Clinical Studies ( 14.1 )] . Patients randomized to the VEN+G arm were treated with VENCLEXTA and obinutuzumab in combination for six cycles, then with VENCLEXTA as monotherapy for an additional six cycles. Patients initiated the first dose of the 5-week ramp-up for VENCLEXTA on Day 22 of Cycle 1 and once completed, continued VENCLEXTA 400 mg orally once daily for a total of 12 cycles. The trial required a total Cumulative Illness Rating Scale (CIRS) >6 or CLcr <70 mL/min, hepatic transaminases and total bilirubin ≤2 times upper limit of normal and excluded patients with any individual organ/system impairment score of 4 by CIRS except eye, ear, nose, and throat organ system. The median duration of exposure to VENCLEXTA was 10.5 months (range: 0 to 13.5 months) and the median number of cycles of obinutuzumab was 6 in the VEN+G arm. Serious adverse reactions were reported in 49% of patients in the VEN+G arm, most often due to febrile neutropenia and pneumonia (5% each). Fatal adverse reactions that occurred in the absence of disease progression and with onset within 28 days of the last study treatment were reported in 2% (4/212) of patients, most often from infection. In the VEN+G arm, adverse reactions led to treatment discontinuation in 16% of patients, dose reduction in 21%, and dose interruption in 74%. Neutropenia led to discontinuation of VENCLEXTA in 2% of patients, dose reduction in 13%, and dose interruption in 41%. Table 12 presents adverse reactions identified in CLL14. Table 12.

VENCLEXTA in Combination with Rituximab The safety of VENCLEXTA in combination with rituximab (VEN+R) (N=194) versus bendamustine in combination with rituximab (B+R) (N=188) was evaluated in MURANO [see Clinical Studies ( 14.1 )] . Patients randomized to VEN+R completed the scheduled ramp-up (5 weeks) and received VENCLEXTA 400 mg once daily, in combination with rituximab for 6 cycles followed by VENCLEXTA monotherapy, for a total of 24 months after ramp-up. At the time of analysis, the median duration of exposure to VENCLEXTA was 22 months and the median number of cycles of rituximab was 6 in the VEN+R arm. Serious adverse reactions were reported in 46% of patients in the VEN+R arm, with most frequent (≥5%) being pneumonia (9%). Fatal adverse reactions that occurred in the absence of disease progression and within 30 days of the last VENCLEXTA treatment and/or 90 days of last rituximab were reported in 2% (4/194) of patients. In the VEN+R arm, adverse reactions led to treatment discontinuation in 16% of patients, dose reduction in 15%, and dose interruption in 71%. Neutropenia and thrombocytopenia each led to discontinuation of VENCLEXTA in 3% of patients. Neutropenia led to dose interruption of VENCLEXTA in 46% of patients.

VENCLEXTA as Monotherapy The safety of VENCLEXTA was evaluated in pooled data from three single-arm trials (M13-982, M14-032, and M12-175). Patients received VENCLEXTA 400 mg orally once daily after completing the ramp-up phase (N=352). The median duration of treatment with VENCLEXTA at the time of data analysis was 14.5 months (range: 0 to 50 months). Fifty-two percent of patients received VENCLEXTA for more than 60 weeks. In the pooled dataset, the median age was 66 years (range: 28 to 85 years), 93% were White, and 68% were male. The median number of prior therapies was 3 (range: 0 to 15). Serious adverse reactions were reported in 52% of patients, with the most frequent (≥5%) being pneumonia (9%), febrile neutropenia (5%), and sepsis (5%). Fatal adverse reactions that occurred in the absence of disease progression and within 30 days of venetoclax treatment were reported in 2% of patients in the VENCLEXTA monotherapy studies, most often (2 patients) from septic shock. Adverse reactions led to treatment discontinuation in 9% of patients, dose reduction in 13%, and dose interruption in 36%. The most frequent adverse reactions leading to drug discontinuation were thrombocytopenia and autoimmune hemolytic anemia. The most frequent adverse reaction (≥5%) leading to dose reductions or interruptions was neutropenia (8%). Table 16 presents adverse reactions identified in these trials. Table 16.

Important Adverse Reactions in CLL/SLL Tumor Lysis Syndrome Tumor lysis syndrome is an important identified risk when initiating VENCLEXTA. CLL14 The incidence of TLS was 1% (3/212) in patients treated with VEN+G [see Warnings and Precautions ( 5.1 )] . All three events of TLS resolved and did not lead to withdrawal from the trial. Obinutuzumab administration was delayed in two cases in response to the TLS events. MURANO The incidence of TLS was 3% (6/194) in patients treated with VEN+R. After 77/389 patients were enrolled in the trial, the protocol was amended to incorporate the current TLS prophylaxis and monitoring measures described in sections 2.2 and 2.4 [see Dosage and Administration ( 2.2 , 2.4 )] . All events of TLS occurred during the VENCLEXTA ramp-up period and were resolved within two days. All six patients completed the ramp-up and reached the recommended daily dose of 400 mg of VENCLEXTA. No clinical TLS was observed in patients who followed the current 5-week ramp-up schedule and TLS prophylaxis and monitoring measures [see Dosage and Administration ( 2.2 , 2.4 )] . Rates of laboratory abnormalities relevant to TLS for patients treated with VEN+R are presented in Table 14 . Monotherapy Studies (M13-982 and M14-032) In 168 patients with CLL treated according to recommendations described in sections 2.1 and 2.2, the rate of TLS was 2% [see Dosage and Administration ( 2.2 , 2.4 )] . All events either met laboratory TLS criteria (laboratory abnormalities that met ≥2 of the following within 24 hours of each other: potassium >6 mmol/L, uric acid >476 µmol/L, calcium <1.75 mmol/L, or phosphorus >1.5 mmol/L), or were reported as TLS events. The events occurred in patients who had a lymph node(s) ≥5 cm and/or absolute lymphocyte count (ALC) ≥25 x 10 9 /L. All events resolved within 5 days. No TLS with clinical consequences such as acute renal failure, cardiac arrhythmias, or sudden death and/or seizures was observed in these patients. All patients had CLcr ≥50 mL/min. Laboratory abnormalities relevant to TLS were hyperkalemia (17% all Grades, 1% Grade ≥3), hyperphosphatemia (14% all Grades, 2% Grade ≥3), hypocalcemia (16% all Grades, 2% Grade ≥3), and hyperuricemia (10% all Grades, <1% Grade ≥3). In the initial Phase 1 dose-finding trials, which had shorter (2-3 week) ramp-up phase and higher starting doses, the incidence of TLS was 13% (10/77; 5 laboratory TLS, 5 clinical TLS), including 2 fatal events and 3 events of acute renal failure, 1 requiring dialysis. After this experience, TLS risk assessment, dosing regimen, TLS prophylaxis and monitoring measures were revised [see Dosage and Administration ( 2.2 , 2.4 )] . Acute Myeloid Leukemia VENCLEXTA in Combination with Azacitidine The safety of VENCLEXTA in combination with azacitidine (VEN+AZA) (N=283) versus placebo in combination with azacitidine (PBO+AZA) (N=144) was evaluated in VIALE-A, a double-blind, randomized trial, in patients with newly diagnosed AML [see Clinical Studies ( 14.2 )] . At baseline, patients were ≥75 years of age or had comorbidities that precluded the use of intensive induction chemotherapy based on at least one of the following criteria: baseline ECOG performance status of 2-3, severe cardiac or pulmonary comorbidity, moderate hepatic impairment, CLcr <45 mL/min, or other comorbidity. Patients were randomized to receive VENCLEXTA 400 mg orally once daily after completion of the ramp-up phase in combination with azacitidine (75 mg/m 2 either intravenously or subcutaneously on Days 1-7 of each 28-day cycle) or placebo in combination with azacitidine. Among patients who received VEN+AZA, the median duration of exposure to VENCLEXTA was 7.6 months (range: <0.1 to 30.7 months). Serious adverse reactions were reported in 83% of patients who received VEN+AZA, with the most frequent (≥5%) being febrile neutropenia (30%), pneumonia (22%), sepsis (excluding fungal; 19%), and hemorrhage (6%). Fatal adverse reactions occurred in 23% of patients who received VEN+AZA, with the most frequent (≥2%) being pneumonia (4%), sepsis (excluding fungal; 3%), and hemorrhage (2%). Adverse reactions led to permanent discontinuation of VENCLEXTA in 24% of patients, dose reductions in 2%, and dose interruptions in 72%. Adverse reactions which led to discontinuation of VENCLEXTA in ≥2% of patients were sepsis (excluding fungal; 3%) and pneumonia (2%). The most frequent adverse reaction leading to dose reduction was pneumonia (0.7%). Adverse reactions which required a dose interruption in ≥5% of patients included febrile neutropenia (20%), neutropenia (20%), pneumonia (14%), sepsis (excluding fungal; 11%), and thrombocytopenia (10%). Among patients who achieved bone marrow clearance of leukemia, 53% underwent dose interruptions for absolute neutrophil count (ANC) <500/microliter.

VENCLEXTA in Combination with Azacitidine or Decitabine The safety of VENCLEXTA in combination with azacitidine (N=67) or decitabine (N=13) was evaluated in M14-358, a non-randomized trial of patients with newly diagnosed AML. At baseline, patients were ≥75 years of age, or had comorbidities that precluded the use of intensive induction chemotherapy based on at least one of the following criteria: baseline ECOG performance status of 2-3, severe cardiac or pulmonary comorbidity, moderate hepatic impairment, CLcr <45 mL/min, or other comorbidity [see Clinical Studies ( 14.2 )] . Patients received VENCLEXTA 400 mg orally once daily after completion of the ramp-up phase in combination with azacitidine (75 mg/m 2 either intravenously or subcutaneously on Days 1-7 of each 28-day cycle) or decitabine (20 mg/m 2 intravenously on Days 1-5 of each 28-day cycle). Azacitidine The median duration of exposure to VENCLEXTA when administered in combination with azacitidine was 6.5 months (range: 0.1 to 38.1 months). The safety of VENCLEXTA in combination with azacitidine in this trial is consistent with that of VIALE-A. Decitabine The median duration of exposure to VENCLEXTA when administered in combination with decitabine was 8.4 months (range: 0.5 to 39 months). Serious adverse reactions were reported in 85% of patients who received VENCLEXTA with decitabine, the most frequent (≥10%) being sepsis (excluding fungal; 46%), febrile neutropenia (38%), and pneumonia (31%). One (8%) fatal adverse reaction of bacteremia occurred within 30 days of starting treatment. Permanent discontinuation of VENCLEXTA due to adverse reactions occurred in 38% of patients. The most frequent adverse reaction leading to permanent discontinuation (≥5%) was pneumonia (8%). Dosage reductions of VENCLEXTA due to adverse reactions occurred in 15% of patients. The most frequent adverse reaction leading to dose reduction (≥5%) was neutropenia (15%). Dosage interruptions of VENCLEXTA due to adverse reactions occurred in 69% of patients. The most frequent adverse reactions leading to dose interruption …
Overdosage
There is no specific antidote for VENCLEXTA. For patients who experience overdose, closely monitor and provide appropriate supportive treatment; during ramp-up phase interrupt VENCLEXTA and monitor carefully for signs and symptoms of TLS along with other toxicities [see Dosage and Administration ( 2.2 , 2.3 , 2.4 , 2.5 )] . Based on venetoclax large volume of distribution and extensive protein binding, dialysis is unlikely to result in significant removal of venetoclax.
Use in specific populations
Lactation: Advise women not to breastfeed. ( 8.2 ) Hepatic Impairment: Reduce the VENCLEXTA dose by 50% in patients with severe hepatic impairment. ( 2.7 , 8.7 )
8.1 Pregnancy Risk Summary Based on findings in animals and its mechanism of action [see Clinical Pharmacology ( 12.1 )] , VENCLEXTA may cause embryo-fetal harm when administered to a pregnant woman. There are no available data on VENCLEXTA use in pregnant women to inform a drug-associated risk. Administration of venetoclax to pregnant mice during the period of organogenesis was fetotoxic at exposures 1.2 times the human exposure at the recommended dose of 400 mg daily based on AUC. Advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Data Animal data In embryo-fetal development studies, venetoclax was administered to pregnant mice and rabbits during the period of organogenesis. In mice, venetoclax was associated with increased post-implantation loss and decreased fetal body weight at 150 mg/kg/day (maternal exposures approximately 1.2 times the human exposure at the recommended dose of 400 mg once daily). No teratogenicity was observed in either the mouse or the rabbit.
8.2 Lactation Risk Summary There are no data on the presence of VENCLEXTA in human milk or the effects on the breastfed child or milk production. Venetoclax was present in the milk when administered to lactating rats (see Data) . Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with VENCLEXTA and for 1 week after the last dose. Data Animal Data Venetoclax was administered (single dose; 150 mg/kg oral) to lactating rats 8 to 10 days post-parturition. Venetoclax in milk was 1.6 times lower than in plasma. Parent drug (venetoclax) represented the majority of the total drug-related material in milk, with trace levels of three metabolites.
8.3 Females and Males of Reproductive Potential VENCLEXTA may cause fetal harm when administered to pregnant women [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating VENCLEXTA. Contraception Advise females of reproductive potential to use effective contraception during treatment with VENCLEXTA and for 30 days after the last dose. Infertility Based on findings in animals, VENCLEXTA may impair male fertility [see Nonclinical Toxicology ( 13.1 )] .
8.4 Pediatric Use The safety and effectiveness of VENCLEXTA have not been established in pediatric patients. Juvenile Animal Toxicity Data In a juvenile toxicology study, mice were administered venetoclax at 10, 30, or 100 mg/kg/day by oral gavage from 7 to 60 days of age. Clinical signs of toxicity included decreased activity, dehydration, skin pallor, and hunched posture at ≥30 mg/kg/day. In addition, mortality and body weight effects occurred at 100 mg/kg/day. Other venetoclax-related effects were reversible decreases in lymphocytes at ≥10 mg/kg/day; a dose of 10 mg/kg/day is approximately 0.06 times the clinical dose of 400 mg on a mg/m 2 basis for a 20 kg child.
8.5 Geriatric Use Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Of the 352 patients with previously treated CLL/SLL evaluated for safety from 3 open-label trials of VENCLEXTA monotherapy, 57% (201/352) were ≥65 years of age and 18% (62/352) were ≥75 years of age. Of the 406 patients with CLL/SLL evaluated for safety from VENCLEXTA in combination with rituximab or obinutuzumab, 67% (273/406) were ≥65 years of age and 24% (97/406) were ≥75 years of age. No clinically meaningful differences in safety and effectiveness were observed between older and younger patients in these studies. Of patients that received VENCLEXTA in combination with acalabrutinib in AMPLIFY, 33% (97/291) were ≥65 years of age, and 4.5% (13/291) were ≥75 years of age. In patients 65 years of age or older and younger than age 65, the fatal adverse reactions were 5% and 2.6%, respectively. No clinically relevant differences in efficacy were observed between patients ≥65 years of age and younger adults. Acute Myeloid Leukemia Of the 283 patients who received VENCLEXTA with azacitidine in VIALE-A, 96% were ≥65 years of age and 60% were ≥75 years of age. Of the 13 patients who received VENCLEXTA in combination with decitabine in M14-358, 100% were ≥65 years of age and 62% were ≥75 years of age. Of the 142 patients who received VENCLEXTA in combination with low-dose cytarabine in VIALE-C, 92% were ≥65 years of age and 57% were ≥75 years of age. Clinical studies of VENCLEXTA in patients with AML did not include sufficient numbers of younger adults to determine if patients 65 years of age and older respond differently from younger adults.
8.6 Renal Impairment Due to the increased risk of TLS, patients with reduced renal function (CLcr <80 mL/min, calculated by Cockcroft-Gault formula) require more intensive prophylaxis and monitoring to reduce the risk of TLS when initiating treatment with VENCLEXTA [see Dosage and Administration ( 2.1 , 2.2 , 2.3 , 2.4 ) and Warnings and Precautions ( 5.1 )] . No dose adjustment is recommended for patients with mild, moderate or severe renal impairment (CLcr ≥15 mL/min) [see Clinical Pharmacology ( 12.3 )] .
8.7 Hepatic Impairment No dose adjustment is recommended for patients with mild (Child-Pugh A) or moderate (Child-Pugh B) hepatic impairment. Reduce the dose of VENCLEXTA for patients with severe hepatic impairment (Child-Pugh C); monitor these patients more frequently for adverse reactions [see Dosage and Administration ( 2.5 , 2.7 ) and Clinical Pharmacology ( 12.3 )] .

Clinical pharmacology
12.1 Mechanism of Action Venetoclax is a selective and orally bioavailable small-molecule inhibitor of BCL-2, an anti-apoptotic protein. Overexpression of BCL-2 has been demonstrated in CLL and AML cells where it mediates tumor cell survival and has been associated with resistance to chemotherapeutics. Venetoclax helps restore the process of apoptosis by binding directly to the BCL-2 protein, displacing pro-apoptotic proteins like BIM, triggering mitochondrial outer membrane permeabilization and the activation of caspases. In nonclinical studies, venetoclax has demonstrated cytotoxic activity in tumor cells that overexpress BCL-2.
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.
12.3 Pharmacokinetics Venetoclax mean (± standard deviation) steady state C max was 2.1 ± 1.1 mcg/mL and AUC 0-24h was 32.8 ± 16.9 mcg
- h/mL following administration of 400 mg once daily with a low-fat meal. Venetoclax steady state AUC increased proportionally over the dose range of 150 to 800 mg (0.25 to 1.33 times the maximum approved recommended dosage). The pharmacokinetics of venetoclax does not change over time. Administration of crushed VENCLEXTA tablets has no impact on venetoclax AUC. Absorption Maximum plasma concentration of venetoclax was reached 5 to 8 hours following multiple oral administration under fed conditions. Effect of Food Administration with a low-fat meal (approximately 512 kilocalories, 25% fat calories, 60% carbohydrate calories, and 15% protein calories) increased venetoclax exposure by approximately 3.4-fold and administration with a high-fat meal (approximately 753 kilocalories, 55% fat calories, 28% carbohydrate calories, and 17% protein calories) increased venetoclax exposure by 5.1- to 5.3-fold compared with fasting conditions. Distribution Venetoclax is highly bound to human plasma protein with unbound fraction in plasma <0.01 across a concentration range of 1-30 micromolar (0.87-26 mcg/mL). The mean blood-to-plasma ratio was 0.57. The apparent volume of distribution (Vd ss /F) of venetoclax ranged from 256-321 L in patients. Elimination The terminal elimination half-life of venetoclax was approximately 26 hours. Metabolism Venetoclax is predominantly metabolized by CYP3A in vitro. The major metabolite identified in plasma, M27, has an inhibitory activity against BCL-2 that is at least 58-fold lower than venetoclax in vitro and its AUC represented 80% of the parent AUC. Excretion After single oral dose of radiolabeled [ 14 C]-venetoclax 200 mg to healthy subjects, >99.9% of the dose was recovered in feces (21% as unchanged) and <0.1% in urine within 9 days. Specific Populations No clinically significant differences in the pharmacokinetics of venetoclax were observed based on age (19 to 93 years), sex, weight, mild to severe renal impairment (CLcr 15 to 89 mL/min, calculated by Cockcroft-Gault), or mild to moderate hepatic impairment (normal total bilirubin and aspartate transaminase (AST) > upper limit of normal (ULN) or total bilirubin 1 to 3 times ULN). The effect of end-stage renal disease (CLcr <15 mL/min) or dialysis on venetoclax pharmacokinetics is unknown. Racial or Ethnic Groups No clinically significant differences in the pharmacokinetics of venetoclax were observed in White, Black, and Asian patients enrolled in the United States. Of 771 patients with AML, Asian patients from Asian countries [China (5.6%), Japan (5.5%), South Korea (2.1%), and Taiwan (0.9%)] had 63% higher venetoclax exposure than non-Asian populations. Patients with Hepatic Impairment Following a single dose of VENCLEXTA 50 mg, venetoclax systemic exposure (AUC 0-INF ) was 2.7-fold higher in subjects with severe hepatic impairment (Child-Pugh C) compared to subjects with normal hepatic function [see Dosage and Administration ( 2.7 ) and Use in Specific Populations ( 8.7 )] . No clinically relevant differences in venetoclax systemic exposure were observed between subjects with mild or moderate hepatic impairment and subjects with normal hepatic function. Drug Interactions Studies Clinical Studies No clinically significant differences in venetoclax pharmacokinetics were observed when coadministered with azacitidine, azithromycin, cytarabine, decitabine, gastric acid reducing agents, obinutuzumab, or rituximab. Ketoconazole Concomitant use of ketoconazole (a strong CYP3A, P-gp, and BCRP inhibitor) 400 mg once daily for 7 days increased venetoclax C max by 130% and AUC 0-INF by 540% [see Drug Interactions ( 7.1 )] . Ritonavir Concomitant use of ritonavir (a strong CYP3A, P-gp, and OATP1B1/B3 inhibitor) 50 mg once daily for 14 days increased venetoclax C max by 140% and AUC by 690% [see Drug Interactions ( 7.1 )] . Posaconazole Concomitant use of posaconazole (a strong CYP3A and P-gp inhibitor) 300 mg with VENCLEXTA 50 mg and 100 mg for 7 days resulted in 61% and 86% higher venetoclax C max , respectively, compared with VENCLEXTA 400 mg administered alone. The venetoclax AUC 0-24h was 90% and 144% higher, respectively [see Drug Interactions ( 7.1 )] . Rifampin Concomitant use of a single dose of rifampin (an OATP1B1/1B3 and P-gp inhibitor) 600 mg increased venetoclax C max by 106% and AUC 0-INF by 78%. Concomitant use of multiple doses of rifampin (as a strong CYP3A inducer) 600 mg once daily for 13 days decreased venetoclax C max by 42% and AUC 0-INF by 71% [see Drug Interactions ( 7.1 )] . Warfarin Concomitant use of a single 400 mg dose of VENCLEXTA with 5 mg of warfarin resulted in 18% to 28% increase in C max and AUC 0-INF of R-warfarin and S-warfarin [see Drug Interactions ( 7.2 )] . Digoxin Concomitant use of a single dose of VENCLEXTA 100 mg with digoxin (a P-gp substrate) 0.5 mg increased digoxin C max by 35% and AUC 0-INF by 9% [see Drug Interactions ( 7.2 )] . In Vitro Studies Venetoclax is not an inhibitor or inducer of CYP1A2, CYP2B6, CYP2C19, CYP2D6, or CYP3A4. Venetoclax is a weak inhibitor of CYP2C8, CYP2C9, and UGT1A1. Venetoclax is not an inhibitor of UGT1A4, UGT1A6, UGT1A9, or UGT2B7. Venetoclax is an inhibitor and substrate of P-gp and BCRP and weak inhibitor of OATP1B1. Venetoclax is not an inhibitor of OATP1B3, OCT1, OCT2, OAT1, OAT3, MATE1, or MATE2K.

Warfarin Concomitant use of a single 400 mg dose of VENCLEXTA with 5 mg of warfarin resulted in 18% to 28% increase in C max and AUC 0-INF of R-warfarin and S-warfarin [see Drug Interactions ( 7.2 )] . Digoxin Concomitant use of a single dose of VENCLEXTA 100 mg with digoxin (a P-gp substrate) 0.5 mg increased digoxin C max by 35% and AUC 0-INF by 9% [see Drug Interactions ( 7.2 )] . In Vitro Studies Venetoclax is not an inhibitor or inducer of CYP1A2, CYP2B6, CYP2C19, CYP2D6, or CYP3A4. Venetoclax is a weak inhibitor of CYP2C8, CYP2C9, and UGT1A1. Venetoclax is not an inhibitor of UGT1A4, UGT1A6, UGT1A9, or UGT2B7. Venetoclax is an inhibitor and substrate of P-gp and BCRP and weak inhibitor of OATP1B1. Venetoclax is not an inhibitor of OATP1B3, OCT1, OCT2, OAT1, OAT3, MATE1, or MATE2K.
Carcinogenesis, mutagenesis, fertility
, Mutagenesis, Impairment of Fertility Neither venetoclax nor M27, a major human metabolite, were carcinogenic in a 6-month transgenic (Tg.rasH2) mouse study at oral doses up to 400 mg/kg/day of venetoclax, and at a single oral dose level of 250 mg/kg/day of M27. Venetoclax was not mutagenic in an in vitro bacterial mutagenicity (Ames) assay, did not induce numerical or structural aberrations in an in vitro chromosome aberration assay using human peripheral blood lymphocytes, and was not clastogenic in an in vivo mouse bone marrow micronucleus assay at doses up to 835 mg/kg. The M27 metabolite was negative for genotoxic activity in in vitro Ames and chromosome aberration assays. Fertility and early embryonic development studies were conducted in male and female mice. These studies evaluate mating, fertilization, and embryonic development through implantation. There were no effects of venetoclax on estrous cycles, mating, fertility, corpora lutea, uterine implants or live embryos per litter at dosages up to 600 mg/kg/day. However, a risk to human male fertility exists based on testicular toxicity (germ cell loss) observed in dogs at exposures as low as 0.5 times the human AUC exposure at a dose of 400 mg.
Information for patients
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Medication Guide ). Tumor Lysis Syndrome Advise patients of the potential risk of TLS, particularly at treatment initiation, during the ramp-up phase, and with resumption after an interruption and to immediately report any signs and symptoms associated with this event (fever, chills, nausea, vomiting, confusion, shortness of breath, seizure, irregular heartbeat, dark or cloudy urine, unusual tiredness, muscle or bone pain, and/or joint discomfort) to their health care provider (HCP) for evaluation [see Warnings and Precautions ( 5.1 )] . Advise patients to be adequately hydrated every day when taking VENCLEXTA to reduce the risk of TLS. The recommended volume is 6 to 8 glasses (approximately 56 ounces total) of water each day. Patients should drink water starting 2 days before and on the day of the first dose, and every time the dose is increased [see Dosage and Administration ( 2.4 )] . Advise patients of the importance of keeping scheduled appointments for blood work or other laboratory tests [see Dosage and Administration ( 2.4 )] . Advise patients that it may be necessary to take VENCLEXTA in the hospital or medical office setting to allow monitoring for TLS. Neutropenia Advise patients to contact their HCP immediately if they develop a fever or any signs of infection. Advise patients of the need for periodic monitoring of blood counts [see Warnings and Precautions ( 5.2 )] . Infections Advise patients to contact their HCP immediately if they develop a fever or any signs of infection [see Warnings and Precautions ( 5.3 )] . Drug Interactions Advise patients to avoid consuming grapefruit products, Seville oranges, or starfruit during treatment with VENCLEXTA. Advise patients that VENCLEXTA may interact with some drugs; therefore, advise patients to inform their health care provider of the use of any prescription medication, over-the-counter drugs, vitamins and herbal products [see Contraindications ( 4 ) and Drug Interactions ( 7.1 )] . Immunizations Advise patients to avoid vaccination with live vaccines because they may not be safe or effective during treatment with VENCLEXTA [see Warnings and Precautions ( 5.4 )] . Embryo-Fetal Toxicity Advise pregnant women of the potential risk to the fetus. Advise females or reproductive potential to inform their healthcare provider of a known or suspected pregnancy [see Warnings and Precautions ( 5.5 ) and Use in Specific Populations ( 8.1 )] . Advise female patients of reproductive potential to use effective contraception during therapy and for 30 days after the last dose [see Use in Specific Populations ( 8.3 )] . Lactation Advise women not to breastfeed during treatment with VENCLEXTA and for 1 week after the last dose [see Use in Specific Populations ( 8.2 )] . Infertility Advise males of reproductive potential that VENCLEXTA may impair fertility [see Use in Specific Populations ( 8.3 )] . Administration Advise patients to keep VENCLEXTA in original packaging or container. Advise patients to take VENCLEXTA exactly as prescribed and not to change their dose or to stop taking VENCLEXTA unless they are told to do so by their HCP. Advise patients to take VENCLEXTA orally once daily, at approximately the same time each day, according to their HCP's instructions and that the tablets should be taken with a meal and water [see Dosage and Administration ( 2.8 )] . Advise patients to contact their HCP if they have trouble swallowing VENCLEXTA tablets. A dose in smaller sized tablets may be prescribed, or tablets may be crushed and mixed with ½ cup (4 ounces) of water, apple juice, apple sauce, or yogurt. Take the entire dose immediately with a meal and water. Do not crush more than one dose at a time [see Dosage and Administration ( 2.8 )] . Crushed tablets may cause yellow staining, including of the skin. Consider using disposable gloves when handling crushed tablets. Advise patients that if a dose of VENCLEXTA is missed by less than 8 hours, to take the missed dose right away and take the next dose as usual. If a dose of VENCLEXTA is missed by more than 8 hours, advise patients to wait and take the next dose at the usual time [see Dosage and Administration ( 2.8 )] . Advise patients not to take any additional dose that day if they vomit after taking VENCLEXTA, and to take the next dose at the usual time the following day. Manufactured and Marketed by: AbbVie Inc.
