Read MoreHide Full Article

Shares of ACADIA Pharmaceuticals Inc. (ACAD - Free Report) soared 26.6% after the FDAissued a clear statement reaffirming the positive benefit-risk profile of Nuplazid (pimavanserin) for patients with Parkinson’s disease psychosis. However, shares of the company have decreased 36.5% year to date compared with the industry’s decline of 3.5%.

Nuplazid was approved by the FDA in April 2016 for the treatment of hallucinations and delusions associated with Parkinson’s disease psychosis, (PDP). It is the only drug approved in the United States for this indication. The approval was supported by a phase III study that demonstrated clinically robust and highly statistically significant efficacy, combined with other supportive studies.

There were reports of deaths and serious adverse events (SAEs) with the use of Nuplazid. However, based on post-marketing reports, the FDA concluded that it did not identify any new or unexpected safety findings with Nuplazid, or findings that are inconsistent with the established safety profile currently described in the drug label.

The agency stated that the drug’s benefits outweigh its risks for patients with hallucinations and delusions of Parkinson’s disease psychosis. The FDA said that Nuplazid and other antipsychotics already have warnings on their boxes, indicating a higher risk of death in elderly patients with the use of such drugs.

According to the agency, individuals with Parkinson's disease psychosis are more at risk of death due to their age, disease and other medical conditions. The FDA further added that patients taking Nuplazid for Parkinson’s disease psychosis should continue to use it as prescribed by their health care provider.

The FDA, however, reminded the health care providers to be aware of the risks described in the prescribing information. 

Sales of Nuplazid increased 87% in the second quarter.
