Brief summary
This study was a single-arm, open study. After the screening period, arsenic-resistant APL patients were treated with interferon α-2b, arsenic and venetoclax. The efficacy (ORR) and safety were evaluated.
Detailed description
Eligible APL patients with arsenic-resistant relapse will enter the run-in period, and the subjects in the run-in phase will be treated with arsenic combined with venetoclax. After the run-in period, the patients were treated with interferon α-2b, arsenic trioxide for injection and venetoclax until the outcome of CR/PR/PD/ death/withdrawal/loss to follow-up occurred. Tumor assessments were performed every 4 to 6 weeks (as determined by the investigator) during trial treatment. Those who achieved CR/PR/PD/ withdrawal were then returned to standard treatment (treatment regimen was determined by the clinician), and those who completed the combination treatment period of the trial entered the survival follow-up period.
