Obesity Treatment Candidate Designed to Preserve Lean Body Mass

Toxicokinetic Findings De-Risk Dose Selection and Support Regulatory Pathway Toward IND

MIAMI, Aug. 06, 2026 (GLOBE NEWSWIRE) -- MIRA Pharmaceuticals, Inc. (NASDAQ:MIRA) ("MIRA" or the "Company"), a clinical-stage pharmaceutical company developing novel oral small-molecule therapeutics, today announced positive toxicokinetic findings from a 7-day repeated-dose study of SKNY-1 in Beagle dogs. The study demonstrates dose-dependent systemic exposure and rapid absorption that de-risk dose selection and support advancement toward GLP toxicology studies and IND-enabling development.

The study evaluated SKNY-1 following repeated daily oral dosing in male and female Beagle dogs over 7 days. SKNY-1 demonstrated rapid oral absorption and dose-dependent systemic exposure across the evaluated dose range. Plasma concentrations were comparable between male and female animals.

The data demonstrates evidence of dose-dependent response and systemic accumulation with repeated dosing, providing confidence in dose selection for the planned GLP toxicology program.

"Obesity treatments today often come at the cost of lean muscle loss, which undermines long-term health outcomes," said Erez Aminov, Chairman and Chief Executive Officer of MIRA Pharmaceuticals. "SKNY-1 aims to solve that problem. These toxicokinetic findings de-risk our dose selection, and we're excited to continue advancing SKNY-1 toward IND-enabling development."

Dr. Itzchak Angel, Chief Scientific Advisor of MIRA, added: "Characterizing systemic exposure in a larger animal species is essential for translating to humans. The dose-dependent relationship and rapid absorption in dogs further strengthen our development package and support advancement toward GLP toxicology studies."

These toxicokinetic findings will inform dose selection and study design for the Company's planned GLP-compliant toxicology program. MIRA is advancing SKNY-1 through additional preclinical efficacy and safety studies to build a comprehensive nonclinical package supporting IND-enabling development for obesity.

About SKNY-1

In peer-reviewed preclinical studies published in the International Journal of Molecular Sciences, oral SKNY-1 demonstrated dose-dependent reductions in body weight while preserving lean body mass, along with lipid normalization and reduced hepatic triglyceride accumulation. The compound attenuated compulsive feeding behavior in validated experimental models. In separate behavioral studies, SKNY-1 was devoid of anxiety-related effects despite engaging central cannabinoid pathways, distinguishing it from earlier CB1-targeting therapies. A lead oral formulation demonstrated favorable bioavailability with robust brain penetration and substantial liver exposure, supporting once-daily oral dosing potential.
