Basic Information

• Recruitment Status: ACTIVE_NOT_RECRUITING
• Clinical Phase: PHASE2
• Total Enrollment: 42 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2018-05-15
• Study Completion Date: 2026-10-31

Brief Summary

This study is being done to determine if treatment with azacitidine and venetoclax is effective treatment for elderly patients with acute myeloid leukemia (AML) who have not received previous treatment. Azacitidine and venetoclax will be given as induction treatment followed by venetoclax maintenance treatment for patients who respond to the induction treatment.

Detailed Description

This is a phase 2 study for elderly patients who have not received previous treatment for acute myeloid leukemia (AML). Up to 42 patients will be enrolled. All patients will be treated with azacitidine and venetoclax until a minimal residual disease (MRD) negative response is achieved. Once patients achieve a MRD negative composite response, azacitidine will be discontinued and venetoclax dose will be decreased to "maintenance" dose.

Conditions

Acute Myeloid Leukemia

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Azacitidine and Venetoclax

On day 1 of cycle 1, Azacitidine 75 mg/m2 will be given by injection or infusion, and will continue for 7 days. Azacitidine doses will be given in subsequent cycles for patients who do not achieve response. Venetoclax will be administered orally once daily on days 2 through 28 in cycle 1. Beginning with cycle 2, and each subsequent cycle, venetoclax will be administered Days 1 through 28.

Group Type: EXPERIMENTAL

Azacitidine and Venetoclax

Intervention Type: DRUG

Azacitidine will be given at dose of 75mg/m2 in Cycle 1 days 1-7; repeat in cycle 2 and 3 if no response. Starting on day 2 of cycle 1, venetoclax will be administered orally with doses increased to a target dose of 600 mg (administer 100 mg on day 2, 200 mg on day 3, 400 mg on day 4 and 600 mg on day 5), then 600 mg daily.

Interventions

Azacitidine and Venetoclax

Azacitidine will be given at dose of 75mg/m2 in Cycle 1 days 1-7; repeat in cycle 2 and 3 if no response. Starting on day 2 of cycle 1, venetoclax will be administered orally with doses increased to a target dose of 600 mg (administer 100 mg on day 2, 200 mg on day 3, 400 mg on day 4 and 600 mg on day 5), then 600 mg daily.
