Grace Therapeutics shares tumbled after regulators told the company that the application for its aneurysm treatment could not be approved in its current form.

The stock slid nearly 50%, to $2.21. Shares at one point during Thursday's session touched a 52-week low of $1.79. Year to date, shares have lost 40% of their value.

The Food and Drug Administration sent the biopharma company a Complete Response Letter for its GTx-104 treatment, which is designed to address medical needs in aneurysmal subarachnoid hemorrhage, a brain injury with a high death rate.

The FDA referenced certain items in the chemistry, manufacturing and controls, and non-clinical sections of the drug application that still need work. Grace said it believes it can address the issues in a resubmission of the application.

The flagged issues are related to leachables data for product packaging, non-clinical product toxicology risk assessments and product manufacturing deficiencies at the company's manufacturing site, the company said.

Grace plans to request a meeting with the FDA to clarify the path forward.
