Rhythm Pharmaceuticals Inc. is a commercial-stage biopharmaceutical company focused on developing and commercializing therapies for rare neuroendocrine diseases, particularly those involving hyperphagia and severe obesity.

Headquartered in Boston, Massachusetts, and founded in 2008, it serves patients through specialized healthcare channels, positioning itself as a leader in rare disease therapies within the neuroendocrine space.
