Soleno Therapeutics Inc. has seen its stock price drop by 7.68%, hitting a 5-day low amid ongoing legal troubles.
A securities class action lawsuit has been filed against Soleno, alleging that the company downplayed significant safety risks associated with its DCCR drug (VYKAT™ XR) during clinical trials. This lawsuit follows a previous report that caused a 26% drop in stock price, raising concerns about the drug's commercial viability and investor confidence. The lawsuit claims that these actions have led to substantial investor losses and could have serious implications for the company's future.
The ongoing legal challenges highlight the potential financial repercussions for Soleno and the erosion of market confidence in its products. Investors are urged to stay informed about the developments in this case as it may affect the company's stock performance.

About SLNO
Soleno Therapeutics, Inc. is focused on the development and commercialization of novel therapeutics for the treatment of rare diseases. Its first commercial product, VYKAT XR (diazoxide choline) extended-release tablets, is a once-daily oral treatment for hyperphagia in adults and children four years of age and older with Prader-Willi syndrome (PWS). VYKAT XR contains diazoxide choline, a potent ATP-sensitive potassium (KATP) channel activator. The KATP channels play a central role in the regulation of a number of physiological processes which may otherwise be dysregulated, contributing to the pathophysiology of several diseases. In the context of the underlying genetic or structural defects in PWS, these pathophysiological processes may cumulatively contribute to increases in appetite and aggressive food seeking, lack of satiety, accumulation of excess body fat and the establishment and perpetuation of the obese state. PWS is a rare, complex genetic neurobehavioral/metabolic disorder.
