Summary
This program provides access to esmethadone (REL-1017), an experimental drug, for people with serious depression who have not responded to standard treatments and cannot join other clinical trials. The goal is to offer a potential treatment option when no satisfactory alternative exists. Participants receive esmethadone tablets under the supervision of their treating physician.
