Expanded Access Program

Expanded access, also known as “compassionate use,” refers to the use of an investigational agent outside of a clinical trial. This is a U.S. Food and Drug Administration (FDA) initiative that allows patients with serious illnesses, who have exhausted all other treatment options, the opportunity to access investigational agents that are not yet approved. It is important to remember that the safety and efficacy of these agents have not yet been established. Physicians and patients should discuss all possible benefits and risks before seeking expanded access to an investigational agent.

Kartos Therapeutics will evaluate each request for expanded access to KRT-232. All requests must be submitted to eap@kartosthera.com by a licensed healthcare professional. We will review the request promptly and respond within 48 hours.

For more information on the FDA Expanded Access program, please see the FDA website on Expanded Access, and/or talk to your healthcare provider.
