Single Arm Study of Azacitidine and Venetoclax for Treatment of Newly Diagnosed Fit Acute Myeloid Leukemia Patients

Phase 1

Recruiting

• Conditions: Leukemia, Myeloid, Acute
• Interventions: Drug: Azacitidine; Drug: Venetoclax

• Registration Number: NCT05471700
• Lead Sponsor: Zhujiang Hospital

Brief Summary

The goal of this clinical research study is to evaluate the safety and efficacy of Azacytidine in combination with Venetoclax in patients with newly diagnosed fit acute myeloid leukemia.

Detailed Description

The Study Drug:

Azacitidine is a DNA Demethylated drug, which is approvd for treatment of elderly AML patients Venetoclax targets the anti-apoptotic protein Bcl-2 and the process of oxidative phosphorylation to induce apoptosis of leukemia cells and exhibits anti-tumor activity.

Study Group:

single arm: AZA plus Venetoclax

Study Drug Administration:

Each course is 28 days long. Venetoclax is taken once daily by oral. The doses of Venetoclax is 100 mg on Day 1, 200 mg on Day 2, reaching a target dose of 400 mg on Day 3 and continuing through Day 28. If concomitantly receiving azoles, the dose of Venetoclax will be adjusted according to the instructions. Azacitidine is taken 75mg/m2 on Days 1-7. Subjects would received 1-2 cycles induction therapy. Once get remission, subjects would received the same indution therapy of middle to high dose of cytarabine based chemotherapy at the discretion of the physician for consolidation. Allo-HSCT is suggested for subjects with the moderate to adverse ELN2017 risk.

Study Visit:

After treatment, relapse and survival will be followed monthly by telephone, on-site visits, and/or study medical records for up to two years (calculated from the first day of induction therapy); Thereafter follow-up every 3 months for one year.

Arm && Interventions

Group	Intervention	Description
Azacitidine combined with Venetoclax	Venetoclax	Each course is 28 days long. Subjects with newly diagnosed AML receive Venetoclax once daily by oral. The doses of Venetoclax is 100 mg on Day 1, 200 mg on Day 2, reaching a target dose of 400 mg on Day 3 and continuing through Day 28. If concomitantly receiving azoles, the dose of Venetoclax will be adjusted according to the instructions. At the same time patients will receive Azacitidine 75mg/m2 subcutaneous on Days 1-7.The induction therapy includes 1-2 cycle until subjects get remission. Once complete remission, subjects will receive consolidation. Azacitidine combined with Venetoclax or middle to high dose of arabinoside based chemotherapy would be given at the discretion of the physician.
