TORONTO--(BUSINESS WIRE)--

Antibe Therapeutics Inc. (“Antibe” or the “Company”) (TSXV: ATE, OTCQB: ATBPF) is pleased to announce that its lead drug, ATB-346, met its primary endpoint in the Phase 2B gastrointestinal (“GI”) safety study. The double-blind study was conducted in 244 healthy volunteers and was designed to demonstrate the superiority of ATB-346 in GI safety compared to naproxen, the most prescribed nonsteroidal anti-inflammatory drug (“NSAID”) in the USA. Subjects on ATB-346 exhibited an ulceration rate of 2.5% versus an ulceration rate of 42.1% for subjects on naproxen at the end of the 2-week treatment period, with a very high degree of statistical significance (p<0.001). ATB-346 was also safe and well tolerated.

Antibe’s Chief Scientific Officer, John Wallace, commented, “The successful outcome of this study is the culmination of 15+ years of scientific research, and validates Antibe’s hydrogen sulfide-releasing technology. Gastrointestinal safety has been a major global concern with NSAIDs for decades and we now have clinical data unequivocally demonstrating a solution to this unmet and serious medical problem.”

Subjects received either 250 mg of ATB-346 once-daily, a dose previously shown to be very effective in reducing osteoarthritis-associated pain, or 500 mg of naproxen twice-daily. The primary endpoint for the study was the incidence of gastric or duodenal ulcers of at least 3 mm diameter with unequivocal depth, considered the gold standard in assessing the GI safety of NSAIDs. “The number of subjects that developed ulcers while on treatment with ATB-346 was 3 (out of 118), compared to 53 (out of 126) for subjects treated with naproxen,” remarked John Wallace. “This result was achieved with an impressive level of statistical significance. In addition, the incidence of elevated liver transaminases in the ATB-346 group was consistent with our expectations and the incidence associated with commonly-prescribed NSAIDs.” The study was conducted by Topstone Research Ltd. (“Topstone”) in Toronto, Canada. A detailed summary of the clinical trial results, including secondary endpoints, will be available for release in Q2 2018.

“This extraordinary result exceeded our expectations for ATB-346,” remarked Dan Legault, Antibe’s CEO. “With human proof-of-concept GI safety data now in hand, Antibe will continue its regional licensing discussions and will now engage global pharmaceutical firms to support our objective of reaching a partnering event for the major markets. In parallel, we will conduct our placebo-controlled dose ranging and effectiveness study with a data read-out expected in Q4 2018. As well, we will accelerate development of Antibe’s other novel NSAIDs, including ATB-352, a non-addictive analgesic for the treatment of severe pain that addresses the global opioid crisis.”

Changes to the Board of Directors

The Company is pleased to announce the appointment of Amal Khouri (B.Sc., MBA) to its Board of Directors, effective immediately. Ms. Khouri brings extensive pharmaceutical business development experience to the Company and succeeded Samira Sakhia as of March 19, 2018.

Ms. Khouri has extensive experience in global partnering and licensing deals in the pharmaceutical industry. Her expertise will be a tremendous asset to our Board and shareholders as we prepare to commence global partnering discussions for our lead drug, ATB-346.”

Ms. Khouri has more than 15 years of business development experience in the pharmaceutical industry and is presently Vice President of Business Development at Knight Therapeutics Inc. (“Knight”). Prior to Knight, Ms. Khouri worked at Novartis Pharma for over 7 years, where she held multiple positions within the global business development and licensing team in Basel, Switzerland. Before joining Novartis, she worked in business development at Paladin Labs in roles with increasing responsibilities. Ms. Khouri holds a B.Sc. in Biochemistry from McGill University and an M.B.A. from the University of Ottawa.

About ATB-346

ATB-346 is a hydrogen sulfide-releasing derivative of naproxen. NSAIDs are the most commonly used therapy for osteoarthritis, yet their use is associated with a high incidence of gastrointestinal ulceration and bleeding. NSAIDs are also widely used in a number of conditions, including rheumatoid arthritis, ankylosing spondylitis, and general pain reduction, with a similarly high rate of gastrointestinal ulceration and bleeding. It is well-accepted that patients with these conditions would benefit greatly from an effective, GI-sparing anti-inflammatory/analgesic agent such as ATB-346.
