July 15, 2026 updated by: Gruppo Italiano Malattie EMatologiche dell'Adulto

A Phase IIA Study of Feasibility and Effectiveness of Inotuzumab Ozogamicin (IO) in Adult Patients With B-Cell Acute Lymphoblastic Leukemia With Positive Minimal Residual Disease Before Any Hematopoietic Stem Cell Transplantation

This is a multi-center, phase 2A exploratory study of feasibility and effectiveness of Inotuzumab Ozagomicin in adult patients with Acute Lymphoid Leukemia (ALL) with positive minimal residual disease before any hematopoietic stem cell transplantation.

The study is divided in two cohorts; cohort 1 will enroll 38 Ph+ patients, cohort 2 will enroll 38 Ph- patients, as defined with statistical analysis. The two cohorts will have the same treatment, with the exception of short term and long term maintenance.
