The Albany Gazette - MIRA Pharmaceuticals Reports Positive Unblinded Phase 1 Data for Ketamir-2

MIAMI, FL / ACCESS Newswire / May 14, 2026 / MIRA Pharmaceuticals, Inc. (NASDAQ:MIRA) ("MIRA" or the "Company"), today announced positive unblinded results from its completed Phase 1 clinical trial evaluating Ketamir-2, the Company's proprietary selective oral NMDA receptor modulator.

The randomized, double-blind, placebo-controlled Phase 1 study evaluated the safety, tolerability, and pharmacokinetics of orally administered Ketamir-2 in healthy volunteers across single ascending dose (SAD) and multiple ascending dose (MAD) cohorts.

A total of 57 healthy volunteers were enrolled across seven cohorts, including placebo. All participants completed the study with no withdrawals, and all subjects were fit for discharge following final administration.

No serious adverse events or dose-limiting toxicities were reported during the study. Adverse events observed were predominantly mild in severity. The incidence of subjects reporting adverse events was higher in the placebo group than in the Ketamir-2-treated group.

Pharmacokinetic analysis demonstrated rapid oral absorption and favorable systemic exposure, with dose-proportional Cmax observed across the evaluated dose range. No major differences were observed in pharmacokinetic parameters for Ketamir-2 or its active metabolite, nor-Ketamir-2, between Day 1 and Day 5 of administration, supporting pharmacokinetic consistency across repeated dosing.

The half-life (t1/2) of Ketamir-2 ranged from approximately 2.5 to 7 hours, while the active metabolite nor-Ketamir-2 demonstrated a half-life of approximately 7 to 9 hours, supporting sustained pharmacologic exposure. Based on the observed pharmacokinetic profile of the parent compound and active metabolite, Ketamir-2 may support once-daily administration, subject to further clinical evaluation.

Advancing Toward Phase 2a Development in Chemotherapy-Induced Peripheral Neuropathy (CIPN)

Based on the completed Phase 1 data package, MIRA is advancing preparations for submission of its Phase 2a clinical protocol and supporting documentation to the U.S. Food and Drug Administration under its active Investigational New Drug (IND) application.

The planned proof-of-concept Phase 2a study is expected to evaluate Ketamir-2 in patients with moderate to severe chemotherapy-induced peripheral neuropathy (CIPN), a debilitating neurological complication associated with certain chemotherapy regimens for which there are currently no FDA-approved therapies.

CIPN is characterized by neuropathic pain, numbness, tingling, and sensory dysfunction that may persist long after chemotherapy treatment ends. In severe cases, symptoms may lead to chemotherapy dose reductions or discontinuation of treatment, negatively impacting patient quality of life and treatment continuity.

The global chemotherapy-induced peripheral neuropathy market is projected to reach approximately $1.7 billion by 2035, according to Spherical Insights & Consulting (Chemotherapy-Induced Peripheral Neuropathy Market Report, 2024).

Management Commentary

Erez Aminov, Chairman and CEO of MIRA, stated:

"Ketamir-2 was designed to retain the therapeutic potential of NMDA modulation while minimizing the dissociative effects associated with ketamine. We believe the Phase 1 findings observed to date support that objective and represent an important milestone as we advance toward Phase 2a development."

Dr. Itzchak Angel, Chief Scientific Advisor of MIRA, added:

"The observed pharmacokinetic and CNS tolerability findings support the translational profile of Ketamir-2 and its continued evaluation in neuropathic pain indications requiring chronic treatment."

About Ketamir-2

Ketamir-2 is a proprietary, orally bioavailable investigational new molecular entity designed to selectively modulate the NMDA receptor (PCP binding site) with low binding affinity and limited off-target receptor activity.

In validated preclinical models of neuropathic pain, including paclitaxel-induced neuropathy and sciatic nerve ligation, Ketamir-2 demonstrated superior efficacy compared with ketamine and established neuropathic pain agents, including pregabalin and gabapentin.

Following scientific review, the U.S. Drug Enforcement Administration (DEA) determined that Ketamir-2 is not classified as a controlled substance.

Ketamir-2 has not been approved by the U.S. Food and Drug Administration for any indication, and its safety and efficacy have not been established.
