Our Pipeline

We are studying rare genetic disorders of obesity.
“We know that all obesity is not the same. There are many genes involved in the MC4R pathway associated with severe obesity and insatiable hunger, and we are continuing efforts to explore the effect of these genes on obesity as we uncover the potential of setmelanotide or other products for the treatment of rare genetic disorders of obesity”

– Murray Stewart, MD, Chief Medical Officer

Rhythm’s Pipeline

Setmelanotide is an investigational, melanocortin-4 receptor (MC4R) agonist in late-stage clinical development for the treatment of rare genetic disorders of obesity by directly addressing the underlying cause of obesities driven by genetic deficits in the MC4R pathway.

The FDA has granted Breakthrough Therapy Designation to setmelanotide for the treatment of obesity associated with genetic defects upstream of the MC4 receptor in the leptin-melanocortin pathway, which includes Bardet-Biedl syndrome (BBS), and Alström syndrome. Also, the FDA has granted Orphan Drug Designation for setmelanotide for the treatment of obesity due to POMC or LEPR deficiency, BBS and Alström syndrome. The European Medicines Agency (EMA) has also granted PRIority MEdicines (PRIME) designation for setmelanotide for the treatment of obesity and the control of hunger associated with deficiency disorders of the MC4R pathway. The European Commission has adopted the EMA’s Committee for Orphan Medicinal Products’ positive opinion and designated setmelanotide as an orphan medicinal product for the treatment of patients with obesity due to POMC or LEPR deficiency, BBS and Alström syndrome.

Rhythm’s Marketing Authorization Application for setmelanotide to treat people living with obesity due to POMC, PCSK1 or LEPR deficiency is currently under review by the EMA.
