This study evaluates the combination of the drugs Venetoclax and Azacitidine in patients with advanced BCR-ABL negative myeloproliferative neoplasms. It enrolls patients whose disease has transformed to an accelerated phase (AP) or blast phase (BP) and who have not received prior therapy for it. It is a Phase 2 study and is currently recruiting participants.
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
