About RYTM

Rhythm Pharmaceuticals, Inc. is a biopharmaceutical company with commercial products, dedicated to the discovery, development, and market launch of therapies addressing rare genetic conditions that cause obesity. Its leading pharmaceutical, IMCIVREE, functions as a powerful agonist of the melanocortin-4 receptor (MC4R). This medication is indicated for treating obesity stemming from deficiencies in pro-opiomelanocortin (POMC), proprotein convertase subtilisin/kexin type 1 (PCSK1), or the leptin receptor (LEPR), alongside its use in patients with Bardet-Biedl and Alström syndromes. Furthermore, the company is progressing setmelanotide (the active compound in IMCIVREE) through Phase II clinical trials. These studies are evaluating its potential for a broader spectrum of applications, including obesity caused by heterozygous POMC or LEPR deficiencies, steroid receptor coactivator 1 (SRC1) deficiency, SH2B1 deficiency, MC4 receptor deficiency, and obesity associated with Smith-Magenis syndrome, POMC epigenetic disorders, and other MC4R-related conditions. Rhythm Pharmaceuticals holds a collaborative research agreement with the Clinical Registry Investigating Bardet-Biedl Syndrome. The firm, headquartered in Boston, Massachusetts, was established in 2008 and changed its name from Rhythm Metabolic, Inc. to Rhythm Pharmaceuticals, Inc. in October 2015.
