MIRA Pharmaceuticals Announces Oral Mira-55 Outperformed Injected Morphine in Normalizing Pain and Reducing Inflammation, Supporting Its Planned IND for Chronic Inflammatory Pain

October 16, 2025 at 07:30 AM EDT

Findings show oral Mira-55 fully normalized pain and significantly reduced inflammation, supporting IND plans and reinforcing MIRA's position in a $70 billion non-opioid pain market.

MIAMI, FLORIDA / ACCESS Newswire / October 16, 2025 / MIRA Pharmaceuticals, Inc. (NASDAQ: MIRA) ("MIRA" or the "Company"), a clinical-stage pharmaceutical company developing novel therapies for neurologic, neuropsychiatric, and metabolic disorders, announced new preclinical data showing that oral Mira-55 normalized pain and significantly reduced inflammation, outperforming injected morphine in an established animal model of inflammatory pain.

This study marks the first time inflammation was directly measured alongside pain in MIRA's Mira-55 program. In the Company's prior study, only pain sensitivity was evaluated, with both Mira-55 and morphine administered by injection. The new data expand those findings by demonstrating that oral administration of Mira-55 provided superior pain normalization and direct anti-inflammatory effects, whereas morphine produced only partial and indirect inflammation reduction.

Study Overview and Key Findings

Pain sensitivity was assessed using Von Frey Filament testing, and inflammation was quantified by paw-edema volume in the formalin-induced inflammatory pain model.

Results:

Oral Mira-55 normalized pain thresholds, fully restoring withdrawal responses to baseline and outperformed injected morphine.
Mira-55 significantly reduced inflammation, confirming a direct CB2 receptor-mediated anti-inflammatory mechanism, while morphine showed only partial, centrally mediated effects.
Both treatments provided pain relief, but Mira-55 delivered dual anti-inflammatory and analgesic benefits without sedation or opioid-related risks.

These findings build on previously reported data showing that injected Mira-55 achieved morphine-comparable pain relief, while this new study demonstrates that oral Mira-55 achieved superior pain normalization and direct inflammation reduction. Collectively, the results reinforce Mira-55's potential as a dual-acting, non-opioid therapy that addresses both inflammation and pain through differentiated, CB2-selective mechanisms.

Reducing inflammation is fundamental to treating pain effectively. Inflammation drives the heightened sensitivity of pain-sensing nerves, amplifying pain signals. Traditional opioids only block pain perception in the brain and do not address inflammation, while NSAIDs treat inflammation but carry significant safety risks. By directly targeting inflammation through CB2 receptor activation, Mira-55 addresses both the cause and the perception of pain, offering a differentiated approach that could redefine how chronic inflammation-driven pain is managed.

Leadership Commentary

"These results highlight the strength of our pipeline and the potential of Mira-55 to become a next-generation, non-opioid therapy," said Erez Aminov, CEO of MIRA. "With Mira-55 demonstrating meaningful anti-inflammatory and pain-modulating effects through oral administration, we believe MIRA is well positioned to advance multiple programs addressing some of the largest unmet needs in pain and neuroscience."

Dr. Itzchak Angel, CSA at MIRA, added: "Oral Mira-55's ability to normalize pain and directly suppress inflammation through CB2 activation highlights a major advance in cannabinoid-based therapeutics. These findings strengthen the rationale for moving this compound toward clinical development."

Market Opportunity and Strategic Positioning

Chronic inflammatory pain remains one of the largest and most underserved therapeutic markets, historically dominated by NSAIDs and opioids that carry well-documented safety and dependency risks. Mira-55's CB2-selective mechanism directly targets both pain and inflammation, offering a novel, non-opioid, non-NSAID alternative. The global non-opioid pain treatment market was valued at USD 45.3 billion in 2024 and is projected to reach USD 70.3 billion by 2030, growing at a CAGR of 7.7%. (Grand View Research, 2024)

Broader Preclinical Promise

Beyond its anti-inflammatory and analgesic profile, prior preclinical studies have shown that Mira-55 enhanced memory performance and reduced anxiety-related behavior, suggesting broader neurologic and neuropsychiatric potential.

About Mira-55

Mira-55 is a next-generation analog of marijuana engineered to selectively activate CB2 cannabinoid receptors associated with anti-inflammatory and analgesic effects while minimizing CB1-related psychoactivity. Following scientific review, the U.S. Drug Enforcement Administration (DEA) determined that Mira-55 is not classified as a controlled substance, supporting its favorable regulatory profile and long-term commercial potential.
