## TL;DR

A first-in-class drug that blocks cortisol signalling in tumour cells, approved in 2026 for platinum-resistant ovarian cancer with chemotherapy.

## Summary

Relacorilant is a selective glucocorticoid receptor antagonist that blocks cortisol signalling inside tumour cells, where glucocorticoid receptor activation is a mechanism of chemotherapy resistance, so it restores sensitivity to the taxane given alongside it. Corcept's ROSELLA phase 3 trial showed that relacorilant plus nab-paclitaxel improved both progression-free and overall survival versus nab-paclitaxel alone, and it was approved in Q1 2026 for platinum-resistant ovarian, fallopian tube or primary peritoneal cancer, the first drug in its class. It is taken as 150 mg the day before, the day of and the day after each weekly nab-paclitaxel dose. Whether the approach extends to other chemotherapy-resistant cancers is open. For a newcomer: a drug that removes a stress-hormone shield so chemotherapy works again.
