NCT00043810 ↗	Study of Gelonin Purging of Autologous Stem Cells for Transplantation	Terminated	M.D. Anderson Cancer Center	Phase 1/Phase 2	2002-07-01	Patients with Acute Myelogenous Leukemia or Myelodysplastic are able to achieve a complete remission but fail to achieve a prolonged disease-free survival. High dose chemotherapy and autologous bone marrow transplantation has been shown to be effective in this group of patients but hematopoietic recovery is slow, and infectious or bleeding complications are common. The delay in hematopoietic recover is accentuated by the use of purging techniques. This is a novel purging approach for autologous stem cell transplantation in patients with Acute Myelogenous Leukemia or Myelodysplastic syndrome to allow for rapid engraftment with a lower relapse rate therefore improving the therapeutic outcomes

Myleran (Busulfan) Clinical Trials Update, Market Analysis, and Projections

Last updated: January 27, 2026

Executive Summary

Myleran (busulfan) is an alkylating agent traditionally used in chemotherapy regimens for chronic myelogenous leukemia (CML) and as a conditioning agent prior to stem cell transplants. Despite its long-standing clinical use, recent developments include renewed trials exploring its applications beyond oncology, such as in conditioning regimens for hematopoietic stem cell transplants (HSCT) and potential treatments for rare hematological disorders. The global market remains mature, though emerging niche therapies and regulatory shifts could influence future growth trajectories. This report synthesizes current clinical trials data, measures market size and segmentation, and forecasts industry trends for the upcoming decade.
