We conducted a retrospective study on patients with Philadelphia Chromosome-Positive Advanced Leukemias including Ph+ CML (n=11) and Ph+ ALL (n=5) who received a Olverembatinib-based regimens in our center….The overall response rate of 8 evaluable patients was 100%. CR/CRi rate was 100%, and CCyR/PCyR rates 62.5% vs 37.5%, respectively....Olverembatinib-based regimens show encouraging activity and safety in very heavily pre-treated, advanced Ph+ leukemias.
