Ruxolitinib and chidamide–intensified busulfan/cyclophosphamide conditioning for peripheral blood stem cell transplant
Official title: Ruxolitinib and Chidamide Intensified Bu/CY Conditioning Regimen for Patients With Acute B Cell Lymphoblast Leukemia Underwenting Haploidenticl Peripheral Blood Stem Cell Transplantation
Run by Chinese PLA General Hospital · NCT05088226 · Data updated 2026-11-12
This trial tests whether adding ruxolitinib and chidamide to a busulfan/cyclophosphamide conditioning regimen helps people aged 12–65 with high‑risk B‑cell acute lymphoblastic leukemia who are receiving allogeneic peripheral blood stem cell transplants.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are patients aged 12–65 with high‑risk B‑cell acute lymphoblastic leukemia who are eligible for allogeneic peripheral blood stem cell transplantation (matched sibling, ≥8/10 matched unrelated, or haploidentical donors) and who have adequate liver and kidney function and ECOG ≤2.
✕Probably not a fit
Patients with Philadelphia chromosome–positive ALL, uncontrolled infections, significant organ dysfunction, pregnancy, or inability to comply with the protocol are unlikely to benefit from this regimen.

What this trial studies
This Phase 2 interventional study tests a modified Bu/Cy conditioning regimen intensified with ruxolitinib and chidamide in patients with high‑risk B‑cell acute lymphoblastic leukemia undergoing allogeneic peripheral blood stem cell transplantation, including haploidentical donors. The single‑center trial at Chinese PLA General Hospital will enroll patients aged 12–65 with adequate organ function and ECOG performance status ≤2. Participants receive the intensified conditioning before transplant and are followed for safety, engraftment, graft‑versus‑host disease, relapse, and survival outcomes. The protocol excludes Ph‑positive ALL, pregnant patients, and those with uncontrolled infections or severe mental illness.
Why it matters
Potential benefit: If successful, the regimen could lower relapse risk and improve survival after allogeneic peripheral blood stem cell transplantation for high‑risk B‑cell ALL.
How similar studies have gone: Single‑agent or single‑class use of ruxolitinib or HDAC inhibitors around transplant has shown some promise in limited studies, but combining ruxolitinib and chidamide with Bu/Cy conditioning is a novel approach with limited prior evidence.
