Harmony Biosciences' BP1.15205 Shows Breakthrough Potential as Best-in-Class Narcolepsy Treatment
- Harmony Biosciences presented preclinical data for BP1.15205, a highly potent orexin 2 receptor agonist that demonstrated significant wake-promoting and cataplexy-suppressing effects in narcolepsy mouse models.
- The investigational drug showed exceptional selectivity with >600-fold preference for OX2R over OX1R receptors and produced statistically significant effects at very low oral doses starting at 0.03 mg/kg.
- A first-in-human study is planned for the second half of 2025 with topline data expected in 2026, following completion of regulatory applications to both European and U.S. authorities.
- The compound demonstrated favorable safety profile with no adverse events observed in 3-month toxicology studies at doses up to 300 mg/kg/day across two species.
