Insights

Early preclinical data for MIRA-55 look encouraging but remain preliminary.

MIRA Pharmaceuticals highlights that its optimized oral formulation of MIRA-55 shows favorable oral exposure and reproducible distribution to brain and liver in animal studies. An intravenous reference arm was used to characterize absolute oral bioavailability and select the lead formulation based on its pharmacokinetic profile.

Management links brain exposure to potential modulation of central pain pathways and peripheral tissue distribution to anti-inflammatory effects seen previously. They also note prior preclinical work where oral MIRA-55 normalized pain and reduced inflammation, outperforming injected morphine, and showed a distinct profile from THC, including anxiolytic activity without typical THC-like central nervous system effects.

The company remains in the preclinical stage for MIRA-55 and plans further work to relate tissue exposure, pharmacodynamic activity, and efficacy as development continues. This update is scientifically important for the program but does not yet change revenue or regulatory status, so its impact is primarily on the perceived robustness of the pain pipeline rather than near-term financials.

absolute oral bioavailability medical
"An intravenous reference arm was included to characterize absolute oral bioavailability"
pharmacokinetic profile medical
"support selection of the lead formulation based on its overall pharmacokinetic profile"
The pharmacokinetic profile describes how a drug moves through the body over time, including how quickly it is absorbed, how it spreads, and how it is eventually eliminated. For investors, understanding this profile helps gauge the drug’s effectiveness, safety, and the appropriate dosing schedule, which can influence a company’s potential success and market value. It provides insight into how a medication behaves, impacting its overall commercial viability.
cannabinoid receptor activity medical
"Mira-55 is a next-generation cannabinoid analog designed to modulate cannabinoid receptor activity"
Investigational New Drug (IND) regulatory
"under its active U.S. Investigational New Drug (IND) application for chemotherapy-induced"
An investigational new drug (IND) is a drug or biologic that is being tested but has not yet been approved for general use; it is the application and formal status that allows a company to begin human clinical trials under regulator oversight. Investors care because an IND marks the transition from lab work to human testing — like getting a permit to run real-world experiments — which creates important milestones, costs, timelines and regulatory risk that drive a development-stage company's value.

Item 7.01 Regulation FD Disclosure.

 

On July 10, 2026, MIRA Pharmaceuticals, Inc. (the “Company”) issued a press release announcing positive results from preclinical studies evaluating optimized oral formulations of MIRA-55, the Company’s oral drug candidate being developed as a non-opioid therapy for chronic inflammatory pain.

 

Following evaluation of multiple oral formulations, the Company selected a lead formulation demonstrating favorable oral bioavailability together with sustained systemic exposure and reproducible distribution into both brain and liver tissue following oral administration. The study included an intravenous reference arm to characterize absolute oral bioavailability and support selection of the lead formulation based on its overall pharmacokinetic profile.

 

The Company believes these pharmacokinetic findings further strengthen the development profile of MIRA-55 by demonstrating that the optimized oral formulation provides meaningful systemic exposure together with distribution into pharmacologically relevant tissues related to both central and peripheral mechanisms of chronic inflammatory pain. These findings build upon the Company’s previously reported preclinical studies demonstrating that oral MIRA-55 normalized pain and reduced inflammation in a validated inflammatory pain model, outperforming injected morphine, while also exhibiting a differentiated pharmacological profile relative to THC. In separate mechanistic and behavioral studies, MIRA-55 demonstrated anxiolytic activity, did not produce the characteristic central nervous system effects associated with THC, and was shown to interact with the cannabinoid system through a mechanism distinct from THC.

MIRA Pharmaceuticals Reports Successful Formulation Results Supporting Development of MIRA-55 as a Non-Opioid Oral Therapy for Chronic Inflammatory Pain

 

Optimized Oral Formulation Demonstrates Favorable Oral Bioavailability Together with Robust Brain and Liver Distribution Following Oral Administration

 

MIAMI, FL / ACCESS Newswire / July 10, 2026 / MIRA Pharmaceuticals, Inc. (NASDAQ: MIRA) (“MIRA” or the “Company”), a clinical-stage pharmaceutical company, today announced positive results from preclinical studies evaluating optimized oral formulations of MIRA-55, the Company’s oral drug candidate being developed as a non-opioid therapy for chronic inflammatory pain.

 

Following evaluation of multiple oral formulations, the Company selected a lead formulation demonstrating favorable oral bioavailability together with sustained systemic exposure and reproducible distribution into both brain and liver tissue following oral administration. Collectively, these findings support the continued development of MIRA-55 as an orally administered therapy for chronic inflammatory pain.

 

“Patients deserve safer and more effective non-opioid treatment options for chronic inflammatory pain,” said Erez Aminov, Chief Executive Officer of MIRA Pharmaceuticals. “These formulation and pharmacokinetic findings represent another important step in advancing MIRA-55 as a differentiated oral therapy designed to address that need.”

 

The objective of the study was to optimize the oral formulation of MIRA-55 by comparing multiple formulations in a preclinical pharmacokinetic study. An intravenous reference arm was included to characterize absolute oral bioavailability and support selection of the lead formulation based on its overall pharmacokinetic profile.

 

The selected formulation demonstrated reproducible distribution into both brain and liver tissue following oral administration. Brain exposure may support modulation of central pain-processing pathways, while peripheral distribution may contribute to the anti-inflammatory activity previously observed in MIRA’s preclinical efficacy studies. Together, these findings demonstrate that the optimized formulation successfully delivers MIRA-55 to pharmacologically relevant tissues associated with both central and peripheral mechanisms of chronic inflammatory pain.

 

“Formulation optimization is far more than a pharmaceutical exercise—it is what enables a molecule to consistently engage its intended biological targets,” said Itzchak Angel, Ph.D., Chief Scientific Advisor of MIRA Pharmaceuticals. “The combination of favorable oral exposure together with reproducible brain and peripheral tissue distribution provides important support for MIRA-55’s proposed mechanism of action and its continued development as an oral therapy for chronic inflammatory pain.”

 

 

 

 

Today’s pharmacokinetic findings build upon MIRA’s previously reported preclinical studies demonstrating that oral MIRA-55 normalized pain and reduced inflammation in a validated inflammatory pain model, outperforming injected morphine, while also exhibiting a differentiated pharmacological profile relative to THC. In separate mechanistic and behavioral studies, MIRA-55 demonstrated anxiolytic activity, did not produce the characteristic central nervous system effects associated with THC, and was shown to interact with the cannabinoid system through a mechanism distinct from THC. Collectively, these efficacy, behavioral, mechanistic, and pharmacokinetic findings continue to strengthen the overall development package supporting MIRA-55 as a differentiated oral therapeutic candidate for chronic inflammatory pain.

 

The Company plans to continue evaluating the relationship between tissue exposure, pharmacodynamic activity, and therapeutic efficacy as MIRA-55 advances through additional preclinical development.
