[11 November 2013]
Products Affected - Description
Alteplase Recombinant Lyophilized Powder
Reason for the Shortage
Genentech states the reason for the Cathflo Activase shortage was that rubber stopper particulate matter was found in vials after reconstitution.1,2
Genentech sent out a Dear Pharmacist Letter
on March 22, 2013 containing information about using a 5 micron filter needle after reconstitution of Cathflo Activase.2
Genentech sent out a Dear Pharmacist Letter on September 23, 2013 indicating that new product with different rubber stoppers are now available and filtering is no longer needed. The new product has a purple carton and purple label on the vial to distinguish it from the old white carton and white label on the vial. The package with the white carton and white label requires filtering.3
Cathflo Activase, Lyophilized Powder, Genentech
2 mg vial, package of 1 (NDC 50242-0041-64)
Activase, Lyophilized Powder, Genentech
50 mg vial, package of 1 (NDC 50242-0044-13)
100 mg vial, package of 1 (NDC 50242-0085-27)
Estimated Resupply Dates
Genentech has Cathflo Activase available through wholesalers. Older product must be filtered with a 5 micron filter needle.1
Implications for Patient Care
- Alteplase is a recombinant tissue plasminogen activator that enhances the conversion of plasminogen to plasmin in the presence of fibrin and initiates local fibrinolysis. Alteplase is commercially available as Activase® and Cathflo Activase®.4,5
- Cathflo Activase® is labeled to restore central venous access devices.4
- Activase® is labeled for the management of acute myocardial infarction, acute ischemic stroke, and pulmonary embolism.5
- Use caution when reconstituting Cathflo Activase as two presentations may be on pharmacy shelves. The presentation with white labeling requires a filter needle while the other presentation with purple labeling does not.3
- Rubber stopper particulate matter was found in reconstituted Cathflo Activase® vials in March 2013. These vials can be identified by the white packaging and labeling and require the use of a filter needle. If your pharmacy has existing supplies of the white-labeled Cathflo Activase, ensure that the product is prepared using a filter needle.2
Alternative Agents & Management
- Prior to the commercial availability of Cathflo Activase®, some institutions would reconstitute a 50 mg vial of alteplase, aliquot the product, and then freeze the product until needed. However, this practice increased pharmacy workload and had a higher risk potential according to USP Chapter 797 regulations on sterile compounding.6-13
- Other available thrombolytics include reteplase (Retavase®) and tenecteplase (TNKase®) but neither of these agents is FDA-labeled for catheter clearance.14,15
- There are limited published data reporting the use of reteplase or tenecteplase for catheter clearance in clinical trials.16-21
- Tenecteplase is currently available from the manufacturer but reteplase is unavailable with an estimated release date in the second quarter of 2013.1,22
