( 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 )] .

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
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 )] .

( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact AbbVie Inc. at 1-800-633-9110 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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.

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.
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 )] .
Pregnancy
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.
Pediatric use
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.
Geriatric use
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.
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.

Mechanism of action
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.
