MIRAPharmaceuticals Reports No Brain Toxicity in FDA-Required Study of Ketamir-2, Confirming Absence of Ketamine-Linked Neurotoxicity

On May 6, 2025, MIRA Pharmaceuticals, Inc. (NASDAQ: MIRA) announced the completion of a regulatory-required neurotoxicity study of Ketamir-2, the Company’s novel oral NMDA receptor antagonist. The study was conducted in accordance with FDA guidance as part of the Company’s ongoing clinical development program.

The study evaluated the potential for Ketamir-2 to produce neuropathologic changes, including Olney lesions, which have historically been associated with certain NMDA receptor antagonists such as ketamine and MK-801. The study was conducted in sexually mature Sprague-Dawley rats. Animals were administered high oral doses of Ketamir-2, while a separate positive control group received MK-801. All animals were observed for clinical signs and underwent detailed histopathological brain analysis at two timepoints.

Keyfindings from the study include:

No<br> test article-related mortality or adverse clinical signs were observed in animals treated with Ketamir-2.
No<br> microscopic or macroscopic brain lesions were detected in Ketamir-2-treated groups.
Positive<br> control animals treated with MK-801 showed clear evidence of vacuolation and neuronal necrosis, consistent with Olney-type lesions.

The results of the study indicate that Ketamir-2 did not induce neurotoxic changes under the study conditions.

These findings will be submitted to the U.S. Food and Drug Administration (FDA) as part of MIRA’s ongoing regulatory communications.
