ASH continues to work with Congress, federal agencies, and other stakeholders to ensure continued access to safe and effective hematologic drugs.

New Updates on Hematologic Drug Shortages

Current Shortage of Erwinaze

The U.S. Food and Drug Administration (FDA) recently reported to ASH that Jazz Pharmaceuticals depleted their existing inventory of the critical hematologic therapy Erwinaze. The FDA is working with Jazz Pharmaceuticals to release an additional safe supply of the therapy as soon as possible, but does not have an expected release date at this time.  The most recent lot of Erwinaze was released in May and June 2016 with an FDA-approved letter advising providers about the “particulate matter risks,” noting that reconstituted vials should only be given through intramuscular administration.  ASH will continue to monitor this shortage and provide members with real-time updates.

These drugs are being recalled because they containing active ingredients manufactured before November 2015.

The Companies are asking customers to immediately quarantine inventory of the affected product under their direct control and to contact retail level customers to remove and return any affected inventory.
