Arizona Tribune - MIRA Pharmaceuticals Initiates Final Cohort of Ketamir-2 Phase 1 Clinical Study as Company Prepares for Phase 2a Study

MIAMI, FLORIDA / ACCESS Newswire / February 3, 2026 / MIRA Pharmaceuticals, Inc. (NASDAQ:MIRA) ("MIRA" or the "Company"), a clinical-stage pharmaceutical company developing novel oral therapeutics for neuropathic and inflammation-driven pain conditions, metabolic disorders, and oncology-related indications, today announced that it has initiated dosing in the final cohort of its Phase 1 multiple ascending dose (MAD) clinical trial evaluating Ketamir-2, its lead oral NMDA receptor antagonist.

To date, 50 healthy volunteers have already been dosed, while dosing in the final cohort is underway, with 6 last subjects remaining. The Company expects to complete the Phase 1 clinical program by the end of the first quarter of 2026.

Phase 1 Progress and Phase 2a Development Plans

The ongoing randomized, double-blind, placebo-controlled Phase 1 study is designed to evaluate the safety, tolerability, and pharmacokinetics of single and multiple oral doses of Ketamir-2 in healthy volunteers. Data reviewed to date continue to support advancement of the program, with no serious adverse events reported.

MIRA is actively finalizing its Phase 2a proof-of-concept study in chemotherapy-induced peripheral neuropathy (CIPN), including clinical site selection, and plans to submit the Phase 2a protocol to the U.S. Food and Drug Administration (FDA) following completion of Phase 1. Subject to regulatory feedback, the Company anticipates initiating the Phase 2a study in the second quarter of 2026.

Given the oncology-related nature of CIPN, the lack of FDA-approved therapies, and the significant unmet medical need, the Company intends to pursue FDA Fast Track designation for Ketamir-2 as the program advances into later-stage clinical development.

Chemotherapy-Induced Peripheral Neuropathy Represents a Significant Unmet Medical Need

Chemotherapy-induced peripheral neuropathy is a common and often debilitating complication of cancer treatment, characterized by chronic nerve pain, tingling, numbness, and burning sensations that may persist long after chemotherapy has ended. CIPN can significantly impair quality of life and frequently limits a patient's ability to tolerate or complete potentially lifesaving cancer therapy.

Despite its prevalence and clinical impact, there are currently no FDA-approved treatments for CIPN. Management typically relies on off-label use of antidepressants, anticonvulsants, opioids, or ketamine-based therapies, which often provide limited benefit and may be associated with tolerability, safety, or practicality challenges. Ketamir-2 was designed to address this unmet need as a differentiated, orally administered NMDA receptor antagonist with the potential to provide effective pain relief without the psychoactive effects or administration limitations associated with ketamine.

Strategic Partnering and Scientific Engagement in 2026

As part of its business development strategy, MIRA announced that it will attend the BIO Partnering Investment & Growth Summit, to be held March 2-3, 2026, in Miami, Florida. The Company plans to engage with large and mid-size pharmaceutical companies to introduce its pipeline and advance potential strategic partnership, collaboration, and merger and acquisition discussions.

In addition, MIRA will be presenting Phase 1 data on Ketamir-2 at the American Association for Cancer Research (AACR) Annual Meeting 2026, taking place April 17-22, 2026, at the San Diego Convention Center in San Diego, California.

Pipeline Update Beyond Ketamir-2

MIRA also provided an update on its additional preclinical programs, SKNY-1 and MIRA-55, both of which are currently undergoing CMC optimization, with the objective of advancing each program into IND-enabling status by year-end 2026.

SKNY-1 is a novel, orally administered small-molecule program being developed for weight loss and nicotine addiction. SKNY-1 was designed as an oral therapy intended to avoid the central nervous system-related adverse effects historically associated with prior CB1 receptor antagonists, as well as the muscle loss that has been reported with certain injectable GLP-1-based therapies. Preclinical studies to date support its continued development as a differentiated metabolic and addiction-focused candidate.

MIRA-55 is a preclinical program being developed for inflammatory pain. In preclinical models, MIRA-55 has demonstrated analgesic activity comparable to injected morphine, along with a significant reduction in inflammation. In these studies, MIRA-55 also demonstrated anti-inflammatory effects that outperformed morphine, supporting its potential as a non-opioid approach to inflammatory pain management.

Management Commentary

"We are pleased to have initiated dosing in the final cohort of our Phase 1 study, marking another important execution milestone for Ketamir-2," said Erez Aminov, Chairman and CEO of MIRA. "As we approach completion of Phase 1 and prepare for Phase 2a development in CIPN, we are increasingly focused on advancing partnering discussions while continuing disciplined, data-driven execution across our pipeline."

Dr. Itzchak Angel, CSA of MIRA, added:

"Chemotherapy-induced neuropathic pain remains an area of profound unmet medical need, with no approved therapies and limited effective options for patients. Ketamir-2 was specifically designed to offer a safer, orally administered alternative that targets key pain pathways without the limitations associated with existing treatments. Advancing this program represents an important step toward improving supportive care for oncology patients."
