PANTHERx® Rare Pharmacy Selected by Rhythm Pharmaceuticals to Distribute IMCIVREE™ (setmelanotide) for Chronic Weight Management in Patients with Obesity Due to POMC, PCSK1 or LEPR Deficiency


PITTSBURGH, June 24, 2021 /PRNewswire/ -- PANTHERx® Rare Pharmacy announced today that it was selected by Rhythm as the exclusive U.S. pharmacy distribution partner for IMCIVREE (setmelanotide). The drug was approved by the U.S. Food and Drug Administration (FDA) in  November 2020 for chronic weight management in adult and pediatric patients 6 years of age and older with obesity due to proopiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or leptin receptor (LEPR) deficiency confirmed by genetic testing.

Obesity due to POMC, PCSK1 or LEPR deficiency are ultra-rare diseases caused by variants in POMC, PCSK1 or LEPR genes that impair the melanocortin-4 receptor (MC4R) pathway, which is responsible for regulating hunger, energy expenditure and consequently body weight. People living with obesity due to POMC, PCSK1 or LEPR deficiency struggle with extreme, insatiable hunger beginning at a young age, resulting in early-onset, severe obesity. As an MC4R agonist, IMCIVREE is designed to restore impaired MC4R pathway activity arising due to genetic deficits.  

"As the exclusive U.S. distribution partner for IMCIVREE, PANTHERx is pleased to provide innovative, life-changing medicines and award-winning white-glove services to people living with obesity due to POMC, PCSK1 or LEPR deficiency," said Rob Snyder, President of PANTHERx. "PANTHERx's partnership with Rhythm advances our mutual dedication to improving the lives of members."

PANTHERx supports tens of thousands of patients across the country, addressing the unique needs of every patient and assisting with their personal journey. Our proprietary RxARECARE® programs and SWFT® technology systems have allowed PANTHERx to create fully customizable programs for the 25+ rare and orphan medications dispensed. Communications and support services are tailored to the desires of each patient and the requirements of their life-changing medications. PANTHERx, with its evolving suit of personalized services and culture of sincere care, continues to define rare pharmacy.
