Treatment for newly diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia

A Single-arm, Open-label Study of Olverembatinib, CD3/CD19 Bispecific T-cell Engager, and Chidamide in Patients With Newly Diagnosed Philadelphia Chromosome-positive Acute Lymphoblastic Leukemia

Phase 2 Interventional Nanfang Hospital, Southern Medical University · NCT06220487

This study is testing a new combination treatment for people with newly diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia to see if it can help them achieve complete remission and improve their chances of survival.

What this trial studies

This phase 2, single-arm, open-label study evaluates the efficacy and safety of a combination treatment involving Olverembatinib, a CD3/CD19 bispecific T-cell engager, and Chidamide in patients with newly diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia (Ph+ALL). The study aims to achieve complete molecular remission (CMR) within three months and assess overall survival and event-free survival as secondary endpoints. The approach combines targeted therapies and immunotherapy to improve outcomes for patients who are ineligible for allogeneic hematopoietic stem cell transplantation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with newly diagnosed B-precursor Ph+ ALL who are ineligible for allogeneic hematopoietic stem cell transplantation.

Not a fit: Patients who have previously received systemic chemotherapy or CAR-T therapy for ALL may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve remission rates and survival outcomes for patients with Ph+ALL.

How similar studies have performed: Previous studies have shown promising results with similar approaches, indicating potential for success in this novel treatment regimen.
