Efmody® (modified-release hydrocortisone) receives MHRA approval for adrenal insufficiency in the UK

Stockholm, Sweden  – May 8, 2026 - Immedica Pharma AB is pleased to announce that the UK Medicines & Healthcare products Regulatory Agency (MHRA) has approved Efmody® (modified-release hydrocortisone) for the treatment of adrenal insufficiency in adolescents aged 12 years and over and adults in the United Kingdom.

Adrenal insufficiency is a rare and serious condition in which the body does not produce sufficient amounts of cortisol. Patients require lifelong treatment and careful management to mimic the body’s natural cortisol rhythm.

“The MHRA approval of Efmody is an important step forward for patients living with adrenal insufficiency in the UK,” says Mark Bell, General Manager in the UK & Ireland. “By expanding access to this innovative treatment, we hope to support patients in achieving a better quality of life, with less fatigue.”

The approval is based on final results from study DIUR-016-AI; a double-blind, double-dummy, two-way cross-over, randomised, phase II study of efficacy, safety and tolerability of modified-release hydrocortisones: Chronocort (Efmody) versus Plenadren (hydrocortisone) in AI.

About adrenal insufficiency (AI)
AI is a rare endocrine disorder in which the body’s adrenal glands are unable to produce sufficient cortisol, a hormone essential for metabolic function and the physiological response to stress. The overall prevalence of adrenal insufficiency is estimated at up t0 42 per 100,000 people. Common daily symptoms include fatigue, low blood pressure, nausea, and reduced tolerance to physical and psychological stress. Treatment focuses on maintaining physiological cortisol levels to prevent acute adrenal crises, which can be life-threatening. Glucocorticoid replacement therapy, with hydrocortisone as the standard of care, is the cornerstone of treatment, with most patients requiring lifelong therapy.

About Efmody® (hydrocortisone modified-release hard capsules)
Efmody is indicated in adolescents aged 12 years and over and adults for the treatment of adrenal insufficiency (AI) and the treatment of congenital adrenal hyperplasia (CAH). Efmody is a modified-release preparation of hydrocortisone that has been specifically designed to replicate the natural circadian rhythm of cortisol when given in a twice-a-day "toothbrush" regimen (last thing at night before sleep and first thing in the morning on waking) and can thus provide a more physiological profile.
