Preventing neurotoxicity in leukemia treatment with intrathecal chemotherapy

Intrathecal Chemoprophylaxis to Prevent Neurotoxicity Associated With Blinatumomab Therapy for Acute Lymphoblastic Leukemia

Phase 2 Interventional Northside Hospital, Inc. · NCT05519579

This study is testing if giving a specific chemotherapy directly into the spine can help protect the brain from side effects while treating adults with Acute Lymphoblastic Leukemia.

What this trial studies

This study investigates the use of intrathecal chemotherapy to reduce neurotoxicity associated with blinatumomab therapy in adults with Acute Lymphoblastic Leukemia (ALL). By administering methotrexate before and during blinatumomab treatment, the study aims to maintain the drug's anti-leukemic effects while minimizing adverse neurological effects. Participants will be closely monitored for both efficacy and safety throughout the treatment process.

Who should consider this trial

Good fit: Ideal candidates are adults receiving their first cycle of blinatumomab for relapse/refractory or MRD-positive B-cell Acute Lymphoblastic Leukemia with adequate organ function.

Not a fit: Patients with active CNS involvement by ALL or significant CNS disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of neurotoxicity in patients undergoing treatment for Acute Lymphoblastic Leukemia.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in reducing treatment-related neurotoxicity in other contexts.
