MIRA Pharmaceuticals Announces Acceptance of Peer-Reviewed SKNY-1 Manuscript Highlighting Oral Obesity and Nicotine Addiction Drug Candidate
Rhea-AI Summary
MIRA Pharmaceuticals (NASDAQ:MIRA) announced acceptance of a peer-reviewed manuscript on SKNY-1, its oral investigational candidate for obesity and nicotine addiction, in the International Journal of Molecular Sciences.
The zebrafish preclinical data show dose‑dependent weight loss of about 30%, improved lipid markers, and reduced compulsive feeding and nicotine-seeking, while additional mammalian and safety studies are still required.
Positive
- Peer-reviewed publication of SKNY-1 preclinical data in a scientific journal
- Approximate 30% body-weight reduction after six days at higher oral dose in zebrafish
- Improved total cholesterol, LDL, and hepatic triglyceride levels versus obese controls
- Dose-dependent reduction of high-calorie feeding and nicotine-seeking behaviors
- Leptin and ghrelin gene expression shifted toward wild-type patterns
Negative
- Findings limited to short-term zebrafish preclinical models
- Mammalian studies, pharmacokinetics, toxicology, and regulatory review still required before clinical development decisions
News Market Reaction – MIRA
In the May 13 session, MIRA declined 4.80%, reflecting a moderate negative market reaction.

Key Figures
Historical Context
| Date | Event | Sentiment | 24h Move | Catalyst |
|---|---|---|---|---|
| Mar 23 | Preclinical pain data | Positive | +22.3% | Mira-55 preclinical data showed strong analgesia without THC-like CNS side effects. |
| Mar 4 | Phase 1 completion | Positive | -1.6% | Completed Ketamir-2 Phase 1 dosing in 56 volunteers with no serious adverse events. |
| Feb 3 | Phase 1 cohort update | Positive | -1.6% | Initiated final Ketamir-2 MAD cohort and outlined plans for Phase 2a in CIPN. |
24h Move is the share-price change in the day after each event; other market factors may also have contributed.
Recent positive R&D updates have produced mixed price reactions, with one strong rally but two modest selloffs on otherwise constructive clinical progress.
Over the past few months, MIRA has focused on advancing multiple oral candidates. On Feb 3, 2026 and Mar 4, 2026, it reported steady Phase 1 progress for Ketamir-2, yet shares slipped slightly after each update. In contrast, preclinical data for MIRA-55 on Mar 23, 2026 coincided with a 22.28% gain. Today’s SKNY-1 zebrafish results fit this pattern of early-stage, non-human data helping to build a broader neurology and metabolic pipeline story.

Peer-reviewed publication highlights preclinical findings demonstrating weight loss, lipid normalization, and reduction of compulsive feeding and nicotine-seeking behaviors
MIAMI, FL / ACCESS Newswire / May 13, 2026 / MIRA Pharmaceuticals, Inc. (NASDAQ:MIRA) ("MIRA" or the "Company"), a clinical-stage pharmaceutical company focused on the development of investigational therapeutics for neurologic, neuropsychiatric, and metabolic disorders, today announced the acceptance and publication of a peer-reviewed manuscript describing the preclinical pharmacology and activity of SKNY-1, the Company's oral investigational drug candidate being evaluated for obesity and nicotine addiction, in the International Journal of Molecular Sciences.
The publication, titled "SKNY-1, a THCV Analog, Produces Weight Loss, Lipid Normalization and Attenuation of Reward-Associated Behaviors in an mc4r(G894C) Zebrafish Model of Obesity," describes in vitro pharmacologic characterization and in vivo preclinical findings observed in an MC4R-deficient zebrafish model exhibiting obesity-associated metabolic and reward-related phenotypes.
The full publication is available online through MDPI at International Journal of Molecular Sciences publication.
"Despite significant advances in obesity treatment, existing therapeutic approaches continue to face limitations related to tolerability, long-term adherence, durability of response, and increasing clinical focus on preservation of lean body mass during weight reduction," said Erez Aminov, CEO of MIRA. "We believe the publication of these peer-reviewed findings further supports the differentiated pharmacological profile of SKNY-1 and its potential as a novel oral investigational approach targeting both metabolic and reward-associated pathways."
According to the publication, SKNY-1 demonstrated differential engagement of cannabinoid receptor 1 (CB1) signaling pathways, partial agonist activity at cannabinoid receptor 2 (CB2), and selective in vitro inhibition of monoamine oxidase B (MAO-B) relative to MAO-A. The manuscript further reports that oral administration of SKNY-1 in the mc4r(G894C) zebrafish model was associated with dose-dependent reductions in body weight, modulation of lipid parameters, reduction of hepatic triglyceride accumulation, and attenuation of compulsive feeding and nicotine-seeking behaviors.
The Company previously reported additional preclinical behavioral findings consistent with SKNY-1's differentiated CB1 pathway engagement, including attenuation of anxiety-like behaviors in a validated zebrafish behavioral model evaluating cannabinoid-related central nervous system effects.
Key findings described in the publication include:
Dose-dependent reduction in body weight following six days of oral administration, with the higher dose group demonstrating approximately
30% reduction relative to baseline.No significant reduction in whole-body density observed during the treatment period.
Reductions in total cholesterol, low-density lipoprotein (LDL), and hepatic triglyceride accumulation relative to untreated mc4r(G894C) controls.
Dose-dependent attenuation of high-calorie feeding and nicotine-seeking behaviors in multiple behavioral paradigms.
Modulation of appetite-regulatory leptin and ghrelin gene expression patterns toward wild-type levels.
The publication also discusses limitations associated with currently available obesity therapies and the potential rationale for evaluating differentiated oral therapeutic approaches targeting both metabolic dysregulation and reward-associated behaviors.
Dr. Itzchak Angel, Chief Scientific Advisor at MIRA and corresponding author of the publication, commented:
"The manuscript demonstrates coordinated metabolic and behavioral findings observed with SKNY-1 in a validated preclinical obesity model. We believe these data support continued translational investigation of SKNY-1 and further evaluation of its pharmacological profile in future studies."
The Company noted that the publication describes short-term preclinical findings in zebrafish models and that additional studies, including mammalian studies, pharmacokinetic evaluations, toxicology studies, and regulatory review, will be required before determining whether SKNY-1 may advance toward clinical development.
