Shares of Ocular Therapeutix tumbled in after-hours trading Monday after the company said its eye pain and inflammation treatment OTX-DP didn't meet one of its goals in a late-stage clinical trial.

OTX-DP is a hydrogel plug that is inserted into a patient's tear duct, where it can gradually release small amounts of the steroid dexamethasone into the eye. The plug is designed to liquefy after four weeks. The company is testing OTX-DP as a treatment for ocular inflammation and pain after surgery.

The company said it will meet with regulators to discuss results from the study and its next steps.

Ocular Therapeutix Inc. ran two late-stage trials of OTX-DP. It announced results from the other study in March and said the product met both of the major goals of the trial.

Shares of Ocular dropped $10.95, or 29 percent, to $27.35 in late trading. The Bedford, Massachusetts-based company went public in July with an initial public offering that priced at $13 per share. The stock had nearly tripled in value since then.
