Treosulfan Based Conditioning Acute Myeloid Leukaemia (AML)

February 4, 2010 updated by: medac GmbH

Clinical Phase II Trial to Evaluate the Safety and Efficacy of Treosulfan Based Conditioning Prior to Allogeneic Haematopoietic Stem Cell Transplantation in Patients With Acute Myeloid Leukaemia

This is a multicenter, multinational, non-randomized, non-controlled open-label phase II trial to evaluate the safety and efficacy of treosulfan in a combination regimen with fludarabine as conditioning therapy prior to allogeneic stem cell transplantation (SCT) in patients with AML.

The aim is to demonstrate a clinical benefit compared with historical data on intravenous busulfan (BusulfexTM, BusilvexTM), the only drug so far registered in the indication conditioning before allogeneic stem cell transplantation.
