About SLNO
Soleno Therapeutics, Inc. is a biopharmaceutical company. The Company is focused on developing novel therapeutics for the treatment of rare diseases. The Company’s lead product candidate, diazoxide choline extended-release tablets (DCCR), is for the treatment of Prader-Willi syndrome (PWS) in individuals four years and older who have hyperphagia.

DCCR tablets consist of the active ingredient diazoxide choline, a choline salt of diazoxide, which is a benzothiadiazine. Its proposed mode of action, with targets in the brain, pancreas and fat tissue, has the potential to broadly impact complex diseases like PWS to reduce appetite, reduce food-seeking, decrease insulin and leptin resistance, and reduce body fat. The Company has Breakthrough Therapy and Fast-Track designations in the United States and Orphan Drug designations in the United States and European Union.
