Low-dose venetoclax with itraconazole plus TACL chemotherapy for relapsed/refractory Philadelphia‑negative ALL

Efficacy of Low-dose Venetoclax With Itraconazole + TACL in Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia

Phase 2 Interventional Hospital Universitario Dr. Jose E. Gonzalez · NCT07039877

This trial tests whether adding low‑dose venetoclax (boosted with itraconazole) to a TACL chemotherapy regimen helps people with relapsed or refractory Philadelphia‑chromosome‑negative acute lymphoblastic leukemia achieve remission and get to stem cell transplant.

What this trial studies

This Phase 2, single-center interventional study combines low‑dose venetoclax with itraconazole (a CYP3A inhibitor to increase venetoclax exposure) alongside a pediatric‑inspired TACL chemotherapy backbone (asparaginase, dexamethasone, bortezomib, vincristine, mitoxantrone) in patients with relapsed or refractory Philadelphia‑negative ALL. Eligible patients (ECOG 0–2, no prior organ‑threatening illness, no prior venetoclax) will receive the combination and be monitored for response, safety, and ability to proceed to allogeneic hematopoietic stem cell transplantation. The primary objective is to raise complete response rates compared with historical salvage regimens, with secondary endpoints including event‑free and overall survival and tolerability. Treatments and outcomes are collected at a single site in Monterrey, Mexico, with standard supportive care and toxicity monitoring.

Who should consider this trial

Good fit: Adults with B‑ or T‑cell relapsed or refractory Philadelphia‑chromosome‑negative ALL who are ECOG 0–2, have no significant preexisting organ damage, and have not previously received venetoclax are the ideal candidates.

Not a fit: Patients with isolated CNS relapse, ECOG 3–4, serious prior organ dysfunction, prior hypersensitivity to regimen drugs, or prior venetoclax exposure are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, the regimen could increase complete remission rates and allow more patients to proceed to potentially curative allogeneic stem cell transplantation.

How similar studies have performed: Venetoclax has shown encouraging responses when combined with chemotherapy in small ALL series and is established in other leukemias, but using low‑dose venetoclax boosted with itraconazole alongside the TACL backbone is a novel approach with limited prior data.
