Merck has received approval from the UK's Medicines and Healthcare products Regulatory Agency for its therapy, sotatercept, to treat a rare lung condition.
Sotatercept gained U.S. approval in March 2024 and is sold under the brand name Winrevair. It is also approved in European Union and 30 other markets.
The MHRA's approval is based on data from a study of 323 patients with pulmonary arterial hypertension, in which Merck's therapy was more effective in improving patients' ability to exercise, compared to placebo.
The U.S. drugmaker acquired sotatercept as part of its $11.5 billion acquisition of Acceleron Pharma in 2021. It has been expanding its cardiovascular drugs portfolio as it prepares for a potential hit to sales after key patents for its top-selling cancer therapy Keytruda expire later this decade.
The regulator said sotatercept can be used with other medicines in adults with moderate or marked limitations of physical activity to help improve their exercise capacity.
It said the recommended dosing schedule is one self-administered injection every three weeks.
As of March 2024, there were 9,263 active PAH patients in the UK, according to data from National Health Service.
Patients with pulmonary arterial hypertension have high blood pressure in the vessels that supply blood to the lungs, which makes the heart work harder to pump blood and can cause failure of the organ.
Sotatercept works by targeting the activin protein that is known to play a role in narrowing lung arteries.
Winrevair has garnered sales of $149 million since its launch in March. Analysts expect its sales to exceed $1 billion in 2025, according to data compiled by LSEG. The therapy has a list price of $14,000 per vial in the U.S.
Merck did not respond to a request for comment on pricing and availability of the therapy in the UK
