简要总结
This phase II trial tests how well venetoclax with cladribine and cytarabine alternating with azacitidine and venetoclax works in treating patients with newly diagnosed monocytic acute myeloid leukemia (AML) and active signaling mutated AML. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking BCL-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as cladribine, cytarabine and azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax with cladribine and cytarabine alternating with azacitidine and venetoclax may kill more cancer cells in patients with newly diagnosed monocytic AML and active signaling mutated AML.
详细描述
PRIMARY OBJECTIVE:
I. Assess efficacy of the investigational treatment based on disease remission.
SECONDARY OBJECTIVES:
I. Assess efficacy of the investigational treatment based on clinical response. II. Assess any-cause survival after treatment. III. Assess survival in the absence of treatment failure, hematologic relapse, or progressive disease.
IV. Assess duration of response, based on morphological assessments. V. Assess the safety and tolerability of the regimen.

- •PCBP who are sexually active with sperm-producing persons must use contraception from C1D1 to 30 days after the last dose of venetoclax or to 6 months after the last dose of azacitidine, cladribine, or cytarabine, whichever is later in time
排除标准

- •Another active malignancy within the previous 5 years of C1D1
- •Investigational therapy within 28 days of C1D1, or within 5 half-lives or longer, if known
- •Recent and significant medical interventions, such as major surgery within 28 days or stem cell transplant within 100 days (and without active treatment for graft versus host disease [GVHD]) of C1D
- •Standard of care procedures for patients with hematologic malignancies, such as biopsies and lumbar punctures, are not exclusionary
- •Hypersensitivity to any of the components of the investigational regimen (i.e., cladribine, cytarabine, venetoclax, azacitidine) or any excipients in the formulations
- •Treatment based on agents targeting or inhibiting BCL-2 (for other, prior indication/malignancy) within the previous 5 years
- •History of dysphagia, short-gut syndrome, gastroparesis, or other conditions that limit the ingestion or gastrointestinal absorption of drugs administered orally
- •Use of drugs with documented drug-drug interaction toxicities with the study drugs
- •Strong or moderate CYP3A4 inducers or inhibitors within 2 days or 3 half lives whichever is longer, prior to C1D1 are exclusionary. Dose adjustments and other modifications may be considered if the wash-out period has not been met, with the approval of the investigator and the research pharmacy
- •Uncontrolled infection. Participants with controlled infection must be afebrile and hemodynamically stable for at least 72 hours prior to C1D1 and must be amenable to alternate treatment if current treatment will interact with investigational regimen
- •Active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV). Enrollment of individuals with evidence of chronic HBV or HCV infection will be considered on a case-by-case basis by the principal investigator
- •Individuals with serology positive for human immunodeficiency virus (HIV) and under active treatment with highly active antiretroviral therapy (HAART) (or another therapy that may interfere with metabolism of study agents)
- •Pregnancy at enrollment or unwillingness to stop breastfeeding. Because there is a potential risk for adverse events in nursing infants secondary to treatment of the mother with the chemotherapy agents, breastfeeding be discontinued from start of treatment until 1 week after the final dose of any study drug
- •Uncontrolled intercurrent illness including, but not limited to ongoing or active uncontrolled infection, unstable cardiac or pulmonary function or acute insufficiency (e.g., symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia), or psychiatric illness or social situation that could limit compliance with study requirements

结局指标
主要结局
Composite complete remission (CRc) rate
时间窗: At start of treatment to post-induction disease assessment (Cycle 1 Day 21 or Cycle 2 Day 21. Each cycle is 28 days)
CRc is defined as achievement of complete remission (CR), CR with partial hematologic recovery (CRh) or CR with incomplete blood count recovery (CRi) after induction (or re-induction). The CRc rate will be computed on the safety set and presented with a point-estimate and exact binomial 95% confidence interval (CI). CRc will also be modeled with univariable logistic regressions, applied to the efficacy set, to determine if any baseline patient or disease feature is correlated with clinical response.
次要结局
- Overall survival (OS)(At start of treatment to death up to 2 years)
- Duration of response (DOR)(At first date of documented ≥ MLFS or better to primary refractory disease, hematologic relapse, discontinuation of treatment due to toxicity, disease progression or death up to 2 years)
- Incidence of grade ≥ 3 adverse events (AEs)(At start of treatment up to 30 days after last dose of any study drug)
- Overall response rate (ORR)(At start of treatment to post-induction disease assessment (Cycle 1 Day 21 or Cycle 2 Day 21. Each cycle is 28 days))
- Event-free survival (EFS)(At start of treatment to primary refractory disease, hematologic relapse, discontinuation of treatment due to toxicity, disease progression or death up to 2 years)
- Percentage of patients achieving 80% relative dose intensity(At start of treatment to end of treatment up to 1 year and 5 months)
