MIRA starts MAD Phase 1 of Ketamir-2; 150–600 mg dosing set

MIRA Pharmaceuticals (NASDAQ: MIRA) reported it has initiated the multiple ascending dose (MAD) portion of its ongoing randomized, double-blind, placebo-controlled Phase 1 trial of its oral candidate, Ketamir-2, in healthy volunteers.

Rhea-AI Filing Summary

MIRA Pharmaceuticals (NASDAQ: MIRA) reported it has initiated the multiple ascending dose (MAD) portion of its ongoing randomized, double-blind, placebo-controlled Phase 1 trial of its oral candidate, Ketamir-2, in healthy volunteers. The company also selected chemotherapy-induced peripheral neuropathy (CIPN) as the lead indication for planned Phase 2a evaluation.

This step follows completion of single ascending dose (SAD) dosing, where data reviewed to date showed no serious or dose-limiting adverse events and no clinically significant safety concerns. The MAD phase will test repeat daily oral dosing from 150 mg to 600 mg for five days to further assess safety, tolerability, and pharmacokinetics, with analyses to characterize absorption and half-life after unblinding.

MIRA highlighted preclinical data in neuropathic pain models in which Ketamir-2 outperformed ketamine, gabapentin, and pregabalin, and noted CIPN lacks FDA-approved therapies. The company believes Ketamir-2 may be considered for Fast Track designation.

Insights

Clinical development analyst

Early-stage progress: MAD dosing underway; CIPN chosen for Phase 2a.

MIRA advanced Ketamir-2 into the MAD portion of a Phase 1 trial after completing SAD dosing with no serious or dose-limiting adverse events reported to date. The MAD design—repeat daily oral dosing of 150 mg to 600 mg over five days—targets safety, tolerability, and pharmacokinetics, with absorption and half-life to be characterized after unblinding.

Selecting CIPN as the lead Phase 2a indication aligns with disclosed preclinical signals where Ketamir-2 reduced pain behaviors and restored sensory function across neuropathic pain models, including paclitaxel-induced neuropathy. CIPN currently has no FDA-approved therapies, and the company notes potential consideration for Fast Track.

Impact depends on forthcoming Phase 1 PK/safety details and execution of the Phase 2a plan in CIPN. Subsequent filings may provide study outcomes and regulatory feedback.

MIRA Pharmaceuticals Initiates Multiple Ascending Dose (MAD) Phase 1 Study of Oral Ketamir-2 and Selects Chemotherapy-Induced Neuropathic Pain as Lead Phase 2a Indication

Advancing toward Phase 2a clinical evaluation in chemotherapy-related pain, a condition with no approved treatments and potential for FDA Fast Track consideration

MIRA Pharmaceuticals, Inc. (NASDAQ: MIRA) (“MIRA” or the “Company”) announced that it has initiated the multiple ascending dose (MAD) portion of its ongoing Phase 1 clinical trial, evaluating its lead oral candidate, Ketamir-2, in healthy volunteers. The Company also announced that it has selected chemotherapy-induced peripheral neuropathy (CIPN) as the lead indication for its planned Phase 2a clinical evaluation.

This milestone follows the completion of dosing in the single ascending dose (SAD) portion of the study. According to data reviewed to date, no serious or dose-limiting adverse events were observed, and no clinically significant safety concerns have been reported. Comprehensive pharmacokinetic analyses will be performed following unblinding to further characterize Ketamir-2’s absorption and half-life profile. The ongoing randomized, double-blind, placebo-controlled Phase 1 study is evaluating single and multiple oral doses of Ketamir-2 to assess its safety, tolerability, and pharmacokinetics in healthy volunteers. The MAD portion includes three cohorts of repeat daily oral dosing ranging from 150 mg to 600 mg for five days, building on the safety and PK data from the SAD phase.

Ketamir-2’s advancement is supported by a growing body of preclinical and peer-reviewed research demonstrating activity in validated neuropathic pain models. In these studies, Ketamir-2 outperformed ketamine, gabapentin, and pregabalin in reducing pain behaviors and restoring sensory function across several models of neuropathic pain. In the paclitaxel chemotherapy-induced neuropathy model, Ketamir-2 produced near complete normalization of pain sensitivity and demonstrated greater efficacy than gabapentin, an FDA-approved standard for neuropathic pain.

Chemotherapy-induced peripheral neuropathy (CIPN) is a painful nerve damage condition caused by certain chemotherapy drugs that can result in persistent pain, tingling, numbness, and burning sensations, most commonly in the hands and feet. It affects a large percentage of cancer patients during treatment and often continues after therapy ends, frequently impacting quality of life and treatment continuity. Despite its prevalence, there are no FDA-approved therapies for CIPN. The Company believes that Ketamir-2’s pharmacologic profile and preclinical results support its further development as a potential non-opioid therapy for this indication.

Ketamir-2 is a novel, non-scheduled oral analog of ketamine engineered to overcome limitations associated with ketamine use, including the need for intravenous administration, short duration of action, and undesirable psychoactive effects. The drug has good oral absorption and is adapted for once-daily dosing without hallucinogenic or dissociative effects. Given the absence of FDA-approved treatments for chemotherapy-induced neuropathic pain and the significant medical unmet need in oncology supportive care, the Company believes Ketamir-2 may qualify for consideration of regulatory incentives such as Fast Track designation.
