Artelo Biosciences Receives a Notice of Allowance from the U.S. Patent and Trademark Office for its Lead Investigational Drug Currently in Two Phase 2 Studies

The Patent Claims are for the Intended Commercial Formulation of ART27.13

Expected to Extend Patent Protection for ART27.13 through 2041

SOLANA BEACH, Calif., Aug. 17, 2026 (GLOBE NEWSWIRE) -- Artelo Biosciences, Inc. (Nasdaq: ARTL), a clinical-stage pharmaceutical company focused on modulating lipid-signalling pathways to develop treatments for people living with cancer, pain, dermatologic, or neurological conditions, today announced that the United States Patent and Trademark Office has issued a Notice of Allowance for a U.S. patent application covering the intended commercial formulation of ART27.13, the Company’s peripherally selective cannabinoid agonist currently being evaluated in the Phase 2 CAReS trial for cancer-related anorexia and the Phase 2 DREAM study in patients with glaucoma or ocular hypertension.

The allowed claims protect compositions of ART27.13 dispersed in polyethylene glycol, including the Company’s intended commercial formulation. This development marks a major milestone in Artelo’s global intellectual property strategy and positions the Company for long-term value creation.

“This U.S. Notice of Allowance and near-term expectation of the issuance of the patent further strengthens the intellectual property foundation supporting ART27.13 and its long-term development potential,” said Gregory D. Gorgas, President and Chief Executive Officer of Artelo Biosciences. “As ART27.13 advances in multiple Phase 2 studies, we believe protecting the intended commercial formulation is an important step in building value around the program and preserving opportunities across multiple indications.”

ART27.13 is being evaluated in the Phase 2 portion of CAReS trial targeting cancer-related anorexia. The investigational drug was well tolerated in the Phase 1 stage and showed early signs of stabilizing or reversing weight loss in more than 60% of participants. Interim results from the Phase 2 portion of CAReS demonstrated the ability of the drug to reverse cancer-related anorexia in all patients taking the highest dose whereas the all the participants on placebo continued to lose weight throughout the study.

ART27.13 is also being evaluated in the DREAM study, a Phase 2 in patients with glaucoma or ocular hypertension. The investigator-led study, funded by Glaucoma UK and the HSC R&D Division, is evaluating ART27.13's potential as a once-daily, orally administered treatment to reduce intraocular pressure, with initial results anticipated in the fourth quarter of this year.

About ART27.13 ART27.13 is a novel benzimidazole derivative and dual cannabinoid agonist. Initially developed by AstraZeneca plc, ART27.13 has been in seven clinical studies with over 280 participants. It is being developed as a once-daily, orally administered agent selectively targeting peripheral CB 1 and CB 2 receptors, with the potential to reduce muscle degeneration while improving body weight, appetite, and quality of life in cancer patients. A statistically significant and dose-dependent increase in body weight was observed in people with back pain who were otherwise healthy. Importantly, the drug enables systemic metabolic effects while minimizing central nervous system-mediated toxicity. Artelo is conducting a Phase 2 named the Cancer Appetite Recovery Study (CAReS) evaluating ART27.13 as a supportive care therapy for cancer patients suffering from anorexia and weight loss. Interim Phase 2 data revealed patients who had lost at least 5% of body weight to be included in CAReS and titrated to the highest ART27.13 dose (1300 µg) achieved an average +6% weight gain over 12 weeks, while patients on placebo lost an additional ~5%. Currently, there is no FDA approved treatment for cancer anorexia cachexia syndrome. In addition to CAReS, ART27.13 is also being evaluated in a Phase 2 study in people with glaucoma at a daily dose of 650 µg.
