Expanded Access to Experimental Biologics
Clinical trials are studies of drugs and biologics that are still in development and have not yet been approved by the FDA. Many patients enroll in clinical trials to gain access to investigational therapies and contribute to finding out how well an investigational therapy works, and how safe it is for patients. Obtaining a drug or biologic under an expanded access program may be an option for some patients who are not able to enroll in clinical trials. The FDA has allowed expanded access to experimental drugs and biologics since the 1970s. That access has allowed tens of thousands of patients with HIV/AIDS, cancer, and other conditions to receive promising therapies when no approved alternative is available.

If there is an emergency that requires the patient to be treated before a written submission can be made, FDA may allow the treatment use to proceed without a written submission, provided the applicable criteria are met. In an emergency situation, the request to use the drug may be made via telephone, fax, or other means of electronic communication, and authorization to ship and use the drug may be given by the FDA official over the telephone.
