Corcept Therapeutics Initiates Phase 1b Trial of Relacorilant Plus Pembrolizumab (Keytruda®) in Patients with Adrenal Cancer with Cortisol Excess

MENLO PARK, Calif., March 15, 2021 (GLOBE NEWSWIRE) — Corcept Therapeutics Incorporated (NASDAQ: CORT), a commercial-stage company engaged in the discovery and development of drugs to treat severe metabolic, oncologic and psychiatric disorders by modulating the effects of cortisol, today announced enrollment of the first patient in the Phase 1b trial of relacorilant in combination with the PD-1 checkpoint inhibitor pembrolizumab (Merck’s medication, Keytruda^®) in patients with adrenal cancer with cortisol excess.

“Cortisol activity blunts the cancer-killing attributes of immunotherapeutic agents such as checkpoint inhibitors,” said Andreas Grauer, MD, Corcept’s Chief Medical Officer, “which may be why pembrolizumab is rarely effective as monotherapy in patients with adrenal cancer with cortisol excess. Our trial will examine whether adding relacorilant to pembrolizumab therapy will reduce cortisol-activated immune suppression sufficiently to help pembrolizumab achieve its intended tumor-killing effect, while relacorilant treats the Cushing’s syndrome caused by excess cortisol activity.”

The open-label, Phase 1b trial has a planned enrollment of 20 patients with metastatic or unresectable adrenal cancer with cortisol excess at five sites in the United States.
