Artelo Biosciences Announces Positive Results with ART27.13 in a Nonclinical Model of Paclitaxel-Induced Peripheral Neuropathy
Rhea-AI Summary
Artelo Biosciences (Nasdaq: ARTL) reported new nonclinical data showing its peripherally restricted dual cannabinoid receptor agonist ART27.13, currently in Phase 2 development for cancer-related anorexia cachexia syndrome (CACS), reduced neuropathic pain-associated behaviors in a paclitaxel-induced peripheral neuropathy model in both male and female animals.
According to Artelo Biosciences, repeated dosing with ART27.13 decreased mechanical allodynia and thermal hyperalgesia, supporting further evaluation in oncology supportive care. Interim results from the CAReS Phase 2 study in CACS previously showed encouraging trends in body weight, lean body mass, activity levels, and a favorable safety profile at doses up to 1300 µg/day, in an indication with no FDA-approved treatments.

Expands potential benefit for treating neuropathic pain in cancer patients, particularly those experiencing weight loss due to cancer
Findings suggest broader utility in cancer supportive care, building on interim findings from CAReS Phase 2 clinical study which demonstrated improvements in body weight, lean body mass and activity levels
SOLANA BEACH, Calif., July 13, 2026 (GLOBE NEWSWIRE) -- Artelo Biosciences, Inc. (Nasdaq: ARTL) (“Artelo” or the “Company), 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 promising results from nonclinical studies in neuropathic pain with ART27.13, the Company's proprietary peripherally restricted cannabinoid receptor agonist, currently in Phase 2 clinical development evaluating patients experiencing cancer-related anorexia cachexia syndrome (CACS).
To determine whether ART27.13 has the potential to address neuropathic pain in cancer patients, researchers at Artelo investigated its proprietary dual cannabinoid agonist in a nonclinical model of paclitaxel-induced peripheral neuropathy, a debilitating side effect that affects approximately
Results demonstrated that repeated dosing with ART27.13 reduced neuropathic pain-associated behaviors (mechanical allodynia and thermal hyperalgesia) in both male and female paclitaxel-treated animals, supporting further exploration of the compound in oncology supportive care settings.
“Chemotherapy-induced peripheral neuropathy can significantly affect patient quality of life and may limit cancer treatment adherence,” said George Warren, Ph.D., lead scientist at Artelo Biosciences and presenter of the pain study results at the International Cannabinoid Research Society (ICRS) 2026 Annual Symposium recently held in Dijon, France. “The results observed in this model suggest that ART27.13 may have broader applications in cancer supportive care beyond CACS. We have incorporated several pain endpoints into the Cancer Appetite Recovery Study (CAReS) trial and, we look forward to reviewing these upon study completion to determine if the analgesic potential of ART27.13 in a cancer setting translates into the clinic.”
CACS affects up to
“Interim CAReS results, and the new data in neuropathic pain, suggests peripheral cannabinoid receptor modulation may influence multiple pathways associated with appetite regulation, metabolism, body composition and symptom management, particularly chemotherapy-induced neuropathic pain, in patients with cancer,” said Professor Saoirse E. O'Sullivan, Vice President of Translational Science at Artelo Biosciences and presenter of the interim results from CAReS. “Importantly, the supportive care opportunity for ART27.13 may extend beyond appetite stimulation and weight maintenance, as demonstrated by additional research presented at ICRS.”
“Despite its significant impact on patient outcomes and quality of life, CACS remains an area of substantial unmet medical need with limited therapeutic options available to patients and physicians,” continued Professor O’Sullivan. “The trends observed in body composition and activity measures from CAReS are particularly encouraging given the profound impact these factors can have on patients living with CACS.”

About ART27.13
ART27.13 is a novel cannabinoid receptor agonist being developed as supportive care for people with cancer experiencing anorexia and cachexia. Administered orally once daily, the treatment goals with ART27.13 are to improve appetite, body weight, and activity levels while preserving muscle and elevating quality of life. Initially developed by AstraZeneca plc, ART27.13 selectively targets peripheral cannabinoid (CB1 and CB2) receptors to avoid the CNS side effects typically associated with some cannabinoids. While exhibiting a favorable safety profile at all doses in the CAReS trial, interim analysis from the blinded and randomized Phase 2 study demonstrated a mean weight gain of over
About CAReS
The Cancer Appetite Recovery Study (CAReS) is a Phase 1/2 randomized, placebo-controlled trial of the Company’s lead clinical program, ART27.13, in people with cancer experiencing 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. Interim data from the Phase 2 portion of CAReS showed improvements in lean body mass, weight gain, and activity among patients treated with all doses of ART27.13, particularly at the highest dose, compared to the participants administered placebo.
