Merck & Co. Inc. Secures FDA Approval for WELIREG® as the First Treatment for Advanced Pheochromocytoma and Paraganglioma in the U.S

Merck & Co. Inc., known as MSD outside of the United States and Canada, has announced that the U.S. Food and Drug Administration (FDA) has granted approval for WELIREG® (belzutifan). This marks a significant development as WELIREG becomes the only approved treatment in the United States for adult and pediatric patients aged 12 years and older with locally advanced, unresectable, or metastatic pheochromocytoma or paraganglioma (PPGL). These are rare tumors that originate from the same tissue, but differ in their location of formation. The approval is based on data from the LITESPARK-015 clinical trial, highlighting Merck's commitment to providing innovative therapies for patients with rare diseases.
