Claxven Tablet

Venetoclax is a BCL-2 inhibitor indicated: For the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). 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. Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma Venetoclax is indicated for the treatment of adult patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Acute Myeloid Leukemia Venetoclax 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.

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. Neutropenia: Monitor blood counts. Interrupt dosing and resume at same or reduced dose. Consider supportive care measures. 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. Immunization: Do not administer live attenuated vaccines prior to, during, or after treatment with Venetoclax until B-cell recovery. 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. Treatment of patients with multiple myeloma with Venetoclax in combination with bortezomib plus dexamethasone is not recommended outside of controlled clinical trials. Tumor Lysis Syndrome Tumor lysis syndrome (TLS), including fatal events and renal failure requiring dialysis, has occurred in patients treated with Venetoclax. Venetoclax 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 Venetoclax and at each dose increase. TLS, including fatal cases, has been reported after a single 20 mg dose of Venetoclax. 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 Venetoclax CLL/SLL monotherapy trials. The rate of TLS remained consistent with Venetoclax 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. 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 Venetoclax 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 Venetoclax in combination with low-dose cytarabine (VIALE-C). 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. Abridged from the full prescribing information.

The following clinically significant adverse reactions are described elsewhere in the labeling: Tumor Lysis Syndrome Neutropenia Infections In CLL/SLL, the most common adverse reactions (≥20%) for Venetoclax 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. In CLL/SLL, the most common adverse reactions (≥20%) for Venetoclax when given in combination with acalabrutinib are neutropenia, headache, diarrhea, musculoskeletal pain, and COVID-19. 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. 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 Venetoclax 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 Venetoclax 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 Venetoclax 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 Venetoclax 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.
