Medical College of Wisconsin·interventional·Posted Aug 28, 2017·Updated Apr 29, 2026

In Brief

A Phase 2 clinical trial evaluating Haploidentical Bone Marrow Transplantation, Hydroxyurea, and 6 other interventions for Sickle Cell Disease. Completed, enrolled 95 participants across 32 sites.

Detailed Summary

This is a Phase II, single arm, multi-center trial, designed to estimate the efficacy and toxicity of haploidentical bone marrow transplantation (BMT) in patients with sickle cell disease (SCD). Based on their age and entry criteria patients are stratified into two groups: (1) children with severe SCD; and (2) adults with severe SCD.
