## TL;DR

QUAZAR AML-001 showed that a tablet form of azacitidine taken as maintenance after chemotherapy helped older people with acute myeloid leukaemia live about ten months longer than placebo, and it became the first approved maintenance treatment for the disease.

## Summary

QUAZAR AML-001 was a double-blind, placebo-controlled phase 3 trial in 472 patients aged 55 and over with acute myeloid leukaemia in first complete remission (with or without count recovery) after induction with or without consolidation, who were not candidates for stem-cell transplant. Patients were randomised to oral azacitidine 300 mg or placebo once daily for 14 days per 28-day cycle. The primary endpoint was overall survival.

Median overall survival was 24.7 months with oral azacitidine against 14.8 months with placebo, and relapse-free survival was also longer. Side effects were mainly gastrointestinal symptoms and neutropenia, and quality-of-life scores were maintained. Oral azacitidine (Onureg) was approved in the United States in September 2020 for continued treatment of adults with acute myeloid leukaemia in first remission who cannot complete intensive curative therapy.
