FDA Announces Drug Shortage of Mustargen® (Mechlorethamine HCl for Injection)

In collaboration with the Food and Drug Administration (FDA), and as a service to our members, ASH provides information about newly approved therapies or other important information for patients. This allows the agency to inform hematologists and professionals in hematology-related fields of recent approvals in a timely manner. In providing this information, ASH does not endorse any product or therapy and does not take any position on the safety or efficacy of the product or therapy described. The following is a message from the FDA’s Office of Oncology Drug Products.

Lundbeck Inc., the sole worldwide manufacturer of Mustargen® (mechlorethamine HCl for injection), has informed the FDA that there will be an extended supply shortage of this drug.

A limited supply of Mustargen is expected to be available starting in mid/late April, and will be distributed by Lundbeck Inc. to meet current patient needs, with priority given to sites with patients currently receiving Mustargen. Once this limited supply is exhausted, a shortage is anticipated until early 2011. Pharmacies and physicians’ offices will need to call their distributor/wholesaler to obtain Mustargen on a drop ship basis only in order to meet patient needs when the drug product is released in mid/late April. Given the expected shortage, alternative treatment plans should be made for new patients to avoid interruption to a treatment program that would normally include Mustargen. The FDA has searched but is unaware of any other supplies of mechlorethamine HCl available from any other sources at this time.

Attached please find a letter from the manufacturer, Lundbeck Inc., concerning the shortage: www.fda.gov/downloads/Drugs/DrugSafety/DrugShortages/UCM207369.pdf
