Thiotepa, Cyclophosphamide, Clarithromycin and Cytarabine

Phase 1

Recruiting

• Conditions: Lymphoblastic Lymphoma, Adult; Acute Lymphoblastic Leukemia, Adult; Burkitt Lymphoma
• Interventions: Drug: Thiotepa, cyclophosphamide, cladribine, and cytarabine conditioning regimen

• Registration Number: NCT06060782
• Lead Sponsor: Fifth Affiliated Hospital, Sun Yat-Sen University

Brief Summary

This study is an observational study on the efficacy and safety of auto-HSCT in adult patients with Burkitt lymphoma, lymphoblastic lymphoma, and acute lymphoblastic leukemia who received TCCA conditioning regimen. The study plans to include 28 patients who received the TCCA regimen for pre-transplantation pretreatment before auto-HSCT. Maintenance treatment will be carried out after transplantation for 1 year to observe the efficacy and safety.
