Acadia Pharmaceuticals Inc. announced it plans to raise $150 million in a secondary public offering of its common stock, though it didn’t indicate how it might use the proceeds.

Its lead drug, pimavanserin, is in phase 3 trials for treating Parkinson’s disease-related psychosis and phase 2 drug trials for Alzheimer’s disease-related psychosis. It plans to file a New Drug Application for pimavanserin, with the Food and Drug Administration by the end of 2014, Acadia said in a regulatory filing. The company also has clinical-stage programs for chronic pain and glaucoma in collaboration with Allergan Inc.

The announcement was made after the market closed March 3; shares closed that day at $28.19. The company has a market capitalization of $2.6 billion.

Jefferies LLC and J.P. Morgan Securities LLC are the joint book-running managers for the offering, and Cowen and Co. LLC is the lead manager for the offering.
