Artelo Biosciences Announces Expanded Clinical Data to be Presented on both ART26.12 and ART27.13 at the 8th Annual Cannabinoid & Endocannabinoid Drug Development Summit

October 15, 2025 09:15 ET | Source: Artelo Biosciences ART26.12 Phase 1 Data Demonstrated No Safety Concerns, Predictable Linear Plasma Exposure, and Options for Dosing in Either Fed or Fasted Conditions ART27.13 Interim Phase 2 Data Showed Substantial Weight Gain and Activity Improvements in the Treated Patients versus Placebo SOLANA BEACH, Calif., Oct. 15, 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 that Professor Saoirse O’Sullivan, Vice President of Translational Sciences at Artelo Biosciences, is presenting expanded data from Artelo’s lead Fatty Acid Binding Protein 5 (FABP5) inhibitor, ART26.12, Single Ascending Dose (SAD) Study at the 8th Annual Cannabinoid & Endocannabinoid Drug Development Summit, taking place October 15–16, 2025, in Boston, Massachusetts. In addition, Professor O’Sullivan will be giving additional insights on ART27.13 development progress in cancer-related anorexia with interim data from the Phase 2 portion of the Cancer Appetite Recovery Study (CAReS). During the presentation titled Exploring the Clinical Development of the Fatty Acid Binding Protein 5 (FABP5) Inhibitor ART26.12, Professor O’Sullivan plans to share findings from the Company’s SAD study and preliminary food effect investigation with ART26.12, which evaluated the safety, tolerability, and pharmacokinetics of its FABP5 inhibitor in healthy volunteers. The SAD study demonstrated that ART26.12 at single doses up to 1050 milligrams was safe and well tolerated. Importantly, ART26.12 exhibited predictable linear dose exposure and showed potential dosing flexibility in either fed or fasted states for future studies. These findings support Artelo’s belief that advancement of ART26.12 into multiple ascending dose and proof-of-principle pain studies is warranted. In addition, Professor O’Sullivan will discuss detailed interim data from the CAReS Phase 2 study. In CAReS, Artelo is evaluating ART27.13, the Company’s proprietary dual cannabinoid agonist, versus placebo in a randomized and blinded comparison in cancer patients experiencing anorexia and weight loss. Initial findings show patients receiving up to 1300 micrograms daily on average gained over 6% in weight versus placebo participants losing an additional 5%. Despite receiving up to twice the maximum dose delivered in the Phase 1 stage of CAReS, the safety profile in Phase 2 to date has been similar and well-tolerated. ART27.13 is uniquely positioned as the most clinically advanced small-molecule, orally administered once-daily treatment in development for cancer anorexia. Impacting up to 80% of late-stage cancer patients, currently there are no approved treatments in the US, UK or EU. Regarding Artelo’s innovation leadership and progress in cannabinoid and lipid-signaling therapeutics development, Professor Saoirse O'Sullivan stated, "Having spent my entire career researching the potential medical benefits of modifying the endocannabinoid system, it is gratifying as a scientist and affirming of our research initiatives to be at the Cannabinoid & Endocannabinoid Drug Development Summit presenting two positive clinical studies for two of Artelo’s development candidates that have the potential to impact the devastating effects of peripheral neuropathic pain and anorexia and cachexia syndrome for people living with cancer." About ART26.12ART26.12, Artelo’s lead Fatty Acid Binding Protein 5 (FABP5) inhibitor, is under development as a novel, peripherally acting, non-opioid, non-steroidal analgesic, initially for the treatment of chemotherapy-induced peripheral neuropathy (CIPN) under an investigational new drug application opened with the FDA. Fatty Acid Binding Proteins (FABPs) are a family of intracellular proteins that chaperone lipids important to normal cellular function. FABP is overexpressed and associated with abnormal lipid signaling in a number of pathologies. In addition to ART26.12 in CIPN, Artelo’s extensive library of small molecule inhibitors of FABPs has shown therapeutic promise for the treatment of certain cancers, neuropathic and nociceptive pain, psoriasis, and anxiety disorders. About ART27.13ART27.13 is a novel benzimidazole derivative being developed as a once-daily, orally administered agent selectively targeting peripheral CB1 and CB2 receptors, with the potential to improve body weight, appetite, muscle degeneration, and quality of life in cancer patients. Initially developed by AstraZeneca plc, ART27.13 has been in seven clinical studies with over 280 participants. 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. Having completed a Phase 1 study in cancer patients where ART27.13 demonstrated an excellent safety profile, Artelo is conducting a Phase 2 trial as a supportive care therapy for cancer patients suffering from anorexia and weight loss. Currently, there is no FDA approved treatment for cancer anorexia cachexia syndrome. About CAReSThe Cancer Appetite Recovery Study (CAReS) is a Phase 1/2 randomized, placebo-controlled trial of the Company’s lead clinical program, ART27.13, in patients with cancer anorexia and weight loss. Cancer-related anorexia, or the lack or loss of appetite in the person with cancer, may result from the cancer and/or its treatment with radiation or chemotherapy. It is common for people with cancer to lose weight. Anorexia and the resulting weight loss can affect a patient’s health, often weakening their immune system and causing discomfort and dehydration. A weight loss of more than 5% can predict a poor outcome for cancer patients and a lower response to chemotherapy. The Phase 1 portion of the CAReS study was designed to determine the most effective and safest initial dose of ART27.13 in the Phase 2 stage. The Phase 2 portion of the CAReS study is designed to determine estimates of activity of ART27.13 in terms of lean body mass, weight gain, and improvement of anorexia compared to placebo.
