• Rhythm Pharmaceuticals' setmelanotide has received orphan drug designation from Japan's Ministry of Health for the treatment of acquired hypothalamic obesity, a rare condition affecting an estimated 5,000-8,000 patients in Japan.
• Setmelanotide, a melanocortin-4 receptor agonist, is currently being evaluated in a global Phase 3 trial with topline data expected in Q2 2025, potentially offering the first therapy targeting the underlying biology of this disease.
• The designation follows similar status in Europe, strengthening Rhythm's global strategy to address significant unmet medical needs for patients with hypothalamic obesity caused by brain tumors, traumatic injury, stroke, or inflammation.
