Inotuzumab Ozogamicin in the Treatment of MRD+ After HSCT of ALL

A Multicenter Prospective Clinical Study of Inotuzumab Ozogamicin (INO) in the Treatment of Minimal Residual Disease Recurrent After Hematopoietic Stem Cell Transplantation of Acute Lymphoblastic Leukemia (ALL)

• Status: Recruiting
• Phase: Phase 2
• Study type: Interventional
• Enrollment: 42 (estimated)
• Sponsor: Sheng-Li Xue, MD · Academic / Other
• Sex: All
• Age: 15 Years – 65 Years
• Healthy volunteers: Not accepted

Summary

As part of postremission consolidative therapy, the decision to proceed with hematopoietic stem cell transplantation is a recommendable regimen in ALL therapy. However, The recurrence rate is high after transplantation. Minimal Residual Disease (MRD) is an important factor affecting the effect of HSCT. The hematologic recurrence rate of MRD-positive patients with adult ALL is high. MRD- is associated with better prognosis. Therefore, maintaining MRD- after transplantation is necessary for long-term survival. The purpose of this study is to explore the efficacy and safety of Inotuzumab Ozogamicin in the treatment of minimal residual disease recurrence after HSCT of ALL patients.

Detailed description

As part of postremission consolidative therapy, the decision to proceed with hematopoietic stem cell transplantation is a recommendable regimen in ALL therapy. However, The recurrence rate is high after transplantation. Minimal Residual Disease (MRD) is an important factor affecting the effect of HSCT. The hematologic recurrence rate of MRD-positive patients with adult ALL is high. MRD- is associated with better prognosis. Therefore, maintaining MRD- after transplantation is necessary for long-term survival. INO-VATE confirmed that Inotuzumab Ozogamicin can be used to achieve high remission (CR/CRi) and MRD-negative rates, serving as an effective bridge to HSCT, and it is associated with increased OS and PFS in patients with R/R BCP ALL. The purpose of this study is to explore the efficacy and safety of Inotuzumab Ozogamicin in the treatment of minimal residual disease recurrence after HSCT of ALL patients.
