The European Commission has granted a European Marketing Authorisation for Plenadren (hydrocortisone, modified release tablet), an orphan drug for treatment of adrenal insufficiency in adults, bringing these patients their first pharmaceutical innovation in over 50 years.
Developed by the Swedish specialty pharma company, DuoCort Pharma, Plenadren is a dual release hydrocortisone replacement therapy designed to better mimic the normal physiological cortisol profile in order to improve outcomes for patients suffering from adrenal insufficiency. Plenadren is given as an oral tablet once daily. It has an outer layer releasing hydrocortisone immediately and an inner core releasing the rest of the drug more slowly during the day.
Although glucocorticoid hormone replacement therapy for adrenal insufficiency has been available for decades, studies have recorded complications and comorbidities including premature death, impaired quality of life, increased risk of cardiovascular diseases, and decreased bone mineral density in treated patients, most likely because it is difficult to match the natural secretion pattern of cortisol.
“The marketing authorization for Plenadren in Europe is an important step towards addressing the unmet needs of these patients,” said Maria Forss, CEO, DuoCort Pharma.
The approval of Plenadren follows the positive opinion adopted by the Committee for Medicinal Products for Human Use (CHMP) in July 2011. Plenadren® is now approved for marketing in all countries of the European Union (EU) as well as as in the European Economic Area (EEA), namely Iceland, Norway and Lichtenstein.
Professor Gudmundur Johannsson of the Department of Endocrinology, Sahlgrenska University Hospital, Gothenburg, Sweden, and Chief Medical Officer of DuoCort Pharma, said: “Plenadren offers a welcome new treatment option to help patients suffering from adrenal insufficiency. Plenadren can improve therapy for many of the almost 200,000 patients in Europe who suffer from this disease and who need life-long cortisol replacement therapy for their survival.”
On October 26, 2011, ViroPharma Incorporated signed a definitive agreement to acquire DuoCort Pharma AB. The companies expect to complete the acquisition in November 2011. On closing, ViroPharma will pay an upfront closing cost of 220 million Swedish kroner (SEK) or $33 million in US dollars (USD). Additionally, there are contingent milestone payments of up to 860 million SEK or $130 million USD associated with manufacturing, sales thresholds and territory expansion.
Adrenal insufficiency (cortisol deficiency) is a rare, life-threatening disease that affects patients in their active years. To survive, patients suffering from this disease need lifelong replacement therapy with hydrocortisone. Treatment of adrenal insufficiency involves replacing, or substituting, the hormones that the patient’s own adrenal glands are not producing. Cortisol is replaced using hydrocortisone, the synthetic form of cortisol.
