Shares of Prothena climbed Thursday after the company said a trial of its Parkinson's treatment suggests potential clinical benefits in the early stages of the disease, even though it missed its primary endpoint.

The stock was up 37.5% to $16.41 in recent trading and. It has fallen about 55% this year.

The study, conducted by Roche, investigated prasinezumab in almost 600 people with early-stage Parkinson's disease.

The treatment showed potential clinical effect, including a delay in motor progression, as well as consistent positive trends across multiple secondary and exploratory endpoints. There were no new safety issues.

The results will inform further clinical development of prasinezumab as a potential disease-modifying treatment for Parkinson's patients, the biotechnology company said.

Roche is evaluating the data and will work with health authorities to determine next steps, Prothena said.
