Can GLP-1s heal the brain? Obesity drugs get a makeover for addiction and depression
Eli Lilly presented the first clinical results of brenipatide, a GLP-1 and GIP mimic related to tirzepatide, for alcohol use disorder at the Psych Congress in New Orleans; its half-life is 9–12 days versus 5–7 days for approved GLP-1 drugs. Kariya Pharmaceuticals shared early clinical results of the GLP-1 compound KP405 for Parkinson's disease, and Baseline Therapeutics plans phase III trials of BT-001 for alcohol use disorder starting in early 2027. Academic trials, including a 2025 semaglutide study in alcohol use disorder, have shown reduced craving and heavy drinking, encouraging industry interest in GLP-1 therapies for addiction and other brain disorders.
