Artelo Biosciences Announces Publication of Preclinical Data Demonstrating Superior Efficacy and Bioavailability of ART12.11 in Reducing Stress-Induced Depression and Anxiety Symptoms

SOLANA BEACH, Calif., Sept. 10, 2025 (GLOBE NEWSWIRE) -- Artelo Biosciences, Inc. (Nasdaq: ARTL), a clinical-stage pharmaceutical company focused on modulating lipid-signaling pathways to develop treatments for people living with cancer, pain, dermatologic, or neurological conditions, today announced the publication of new preclinical data on ART12.11, its proprietary cannabidiol:tetramethylpyrazine (CBD:TMP) cocrystal.

The peer-reviewed study, conducted in collaboration with researchers at Western Ontario University, was published in Progress in Neuro-Psychopharmacology and Biological Psychiatry and highlighted that ART12.11 significantly outperformed cannabidiol (CBD) alone in reducing stress-induced depression and anxiety symptoms, while also achieving superior oral bioavailability.

Key Findings

• Enhanced Efficacy: ART12.11 reversed stress-induced behavioral deficits and produced robust anti-depressant and anxiolytic-like effects. These benefits were superior to CBD alone, TMP alone, or a non-crystalline mixture of CBD and TMP.
• Improved Bioavailability: Oral administration of ART12.11 resulted in higher plasma concentrations of CBD and its major metabolite, highlighting improved pharmacokinetic properties over conventional CBD formulations.
• Mechanistic Insights: ART12.11 enhanced activation of the endocannabinoid and serotonergic systems in brain regions critical to mood regulation, including the prefrontal cortex, ventral hippocampus, and nucleus accumbens.
  

These results demonstrate ART12.11’s potential as a differentiated therapeutic for mood and anxiety disorders – markets where limitations of conventional CBD, including inconsistent efficacy and poor bioavailability, have hindered clinical adoption. By addressing these shortcomings, ART12.11 may represent a significant advancement in cannabinoid-based therapeutics for anxiety and depression disorders, supporting Artelo’s broader mission to bring novel, high-value and differentiated treatments to patients.

Professor Saoirse O'Sullivan, Vice President of Translational Sciences, commented, “We are pleased to see the publication of this important work demonstrating the impact of our oral ART12.11 CBD cocrystal in stress-induced anxiety and depression. ART12.11’s ability to improve stress-induced symptoms was not seen with CBD alone, the cocrystal coformer alone, or coadministration of CBD and the cocrystal conformer TMP. This shows the uniqueness of ART12.11.”

Matt Jones, the lead researcher of this work at the University of Western Ontario, said, “In our recent study, we found that ART12.11 produced promising anti-depressant- and anti-anxiety-like effects. Our results suggest that ART12.11 works by selectively influencing serotonergic activity and endocannabinoid signaling – key pathways in mood regulation – while leaving other systems largely unaffected. This selectivity may help maximize therapeutic benefits while minimizing side effects.”

Artelo recently disclosed that the MHRA, the regulatory authority in the UK, has agreed the Company may rely on the substantial body and sufficient nonclinical and clinical evidence for CBD. In addition, the agency affirmed Artelo may leverage the legacy data for TMP, which is expected to provide a scientifically justified basis for its clinical trial application. By streamlining the nonclinical development plan for ART12.11, the MHRA’s guidance is anticipated to reduce costs and enable rapid advancement towards the proposed first human study with ART12.11 planned for next year.

About ART12.11
ART12.11 is Artelo’s wholly owned, proprietary cocrystal composition of cannabidiol (CBD) and tetramethylpyrazine (TMP). Isolated as a single crystalline form, ART12.11 has exhibited better pharmacokinetics and improved efficacy compared to other forms of CBD in nonclinical studies. Greatly enhanced pharmaceutical properties, including physicochemical, pharmacokinetic, and pharmacodynamic advantages have been observed with ART12.11. Artelo believes a more consistent and improved bioavailability profile may ultimately lead to increased safety and efficacy in humans, thus making ART12.11 a preferred CBD pharmaceutical composition. The US issued composition of matter patent for ART12.11 is enforceable until December 10, 2038 and has now been granted or validated in 19 additional countries.
