Excess Cortisol Can Lead to Lasting Changes to Blood Stem Cells

People with active Cushing’s disease show increased production of red blood cells due to the presence of a type of altered blood stem cell that show abnormal activation of glucocorticoid receptor (GR) signaling, a study shows. The GR is the receptor protein activated by glucocorticoids, or steroid hormones, including…

Urinary Cortisol Not Ideal Cushing’s Biomarker, Analysis Suggests

Lowering excess cortisol within cells using SPI-62, an investigational treatment of Cushing’s-related conditions, did not affect urinary cortisol levels, a standard measure of therapy effectiveness in clinical trials, an analysis of previous trial data showed. “Normalized urinary free cortisol, or UFC, is a standard therapeutic target for patients with Cushing’s…

CRN04894 Lowers Blood Cortisol Levels, Top-line Trial Data Show

CRN04894, a first-in-class, experimental oral medication for Cushing’s disease, led to a dose-dependent drop in blood and urine cortisol levels in healthy volunteers, top-line data from a Phase 1 trial showed. According to Crinetics Pharmaceuticals, the therapy’s developer, patient studies are expected to launch later this year. In…

Managing Co-existing Diseases May Improve Survival in Cushing’s

People with Cushing’s syndrome, a group of conditions that includes Cushing’s disease, have a three-times-higher risk of mortality compared with the general population, according to a pooled analysis of multiple studies. Preventing and managing co-existing conditions, especially cardiovascular disease, in addition to treating Cushing’s, may benefit at least half…

Oral ACTH Blocker Safely Reduces Cortisol, Early Data Show

CRN04894, a first-in-class, investigational oral medication to treat Cushing’s disease, demonstrated pharmacologic proof-of-concept with a dose-dependent suppression of cortisol, according to data from a Phase 1 study. CRN04894, developed by Crinetics Pharmaceuticals, is designed to block the interaction (antagonist) between the MC2R receptor, found specifically on the…
