Drug and Biologics Updates

The FDA announced this week that it was exercising its discretion with clozapine’s REMS, citing long wait times and high call volumes that impede patient access to the antipsychotic. The agency clarified that it does not intend to object to the distribution or shipment of clozapine, even if all REMS requirements are not met.

In a sharply worded closing paragraph, the agency notes that it “intends to refer this matter to the FTC, which has the administrative tools and expertise to investigate and combat anticompetitive business practices.”
