Antibe has surmounted the main barrier to safer treatment of pain and inflammation.
Antibe’s drug pipeline targets large markets in non-addictive pain management. Our lead drug, now in late Phase 2B trials, has demonstrated unprecedented safety in the treatment of chronic pain, a condition that affects hundreds of millions of people worldwide. Our second pipeline drug is designed to replace opioids for post-operative pain, directly addressing a worldwide public health crisis. In the longer term, we will exploit our platform to create drugs that address a range of inflammation-based diseases.
We generate revenue through our wholly owned subsidiary, Citagenix Inc., a worldwide distributor of regenerative medicine products for dentists, periodontists and oral surgeons.
Platform for Anti-inflammatory Pain Management
Nonsteroidal anti-inflammatory drugs (NSAIDs) are the main category of drugs used to treat disorders characterized by pain and inflammation, with global sales exceeding $11 billion annually.1 While highly effective, they cause clinically significant gastrointestinal bleeding and ulcers in approximately 25% of users. Despite this longstanding issue, the efficacy and non-addictive nature of NSAIDs position them as drugs-of-choice for physicians and consumers*, with more than 30 billion doses taken annually in the US alone. Notably, NSAIDs have been shown to be as effective as opioids for many types of pain, but are often contraindicated due to the risk of significant gastrointestinal bleeding.
Antibe’s platform targets this major medical problem. By linking a hydrogen sulfide-releasing molecule to an NSAID, we have developed a new generation of best-in-class NSAIDs, delivering anti-inflammatory and pain-relieving effects without damage to the digestive tract. Additionally, clinical trials of our lead drug indicate an opportunity for once-daily administration of a single tablet, as opposed to the requirement for multiple daily dosing with existing NSAIDs.

* Consumers are familiar with aspirin and brands like Advil (ibuprofen), Aleve (naproxen) and Voltaren (diclofenac). Less well-known, the category includes drugs like indomethacin, ketoprofen and ketorolac—effective at reducing severe pain, but with correspondingly more damage to the digestive tract.
An Unmet Need...
1. NSAIDs Pose Significant Gastrointestinal Risks
NSAIDs have become the dominant category for treating pain and inflammation. While they are known to be effective, they also pose serious, widely recognized gastrointestinal risks. Protecting the digestive tract without compromising cardiovascular health is the primary market need (upper right quadrant).

2. Emergence of Selective COX-2 Inhibitors
Beginning in the late 1990s, “COX-2 selective” NSAIDs were introduced to improve gastrointestinal safety. They were rapidly adopted, with two products reaching $1 billion in first year sales. However, most were later withdrawn or discontinued due to severe cardiovascular events.

3. ATB-346 Addresses Major Unmet Need
Now in late Phase 2 trials, ATB-346 has already demonstrated dramatic gastrointestinal safety compared to naproxen, the most prescribed NSAID in the US.
Lead Drug and Pipeline
ATB-346, our lead drug, targets chronic pain and inflammation arising from a wide range of medical conditions. In March 2018, it was shown to be unequivocally superior to naproxen in gastrointestinal safety (a 2.5% ulceration rate, compared to 42.1% for naproxen) in a Phase 2B double-blind, head-to-head clinical trial (see March 2019 paper in the British Journal of Pharmacology). These results indicate that Antibe has surmounted the main barrier to non-addictive control of pain and inflammation. ATB-346 is in late Phase 2B trials.

Intellectual property
Antibe’s intellectual property interest in ATB-346 is well-protected. Composition of matter patents have been granted in major markets, including the US, the EU and Japan. Antibe anticipates exclusive market protection in the US beyond 2031, and in the EU beyond 2033.
Commercialization
ATB-346 has already been licensed in 57 countries to three licensees (see map below). These markets include Canada, Greece, Israel, and Russia. The most recent is an exclusive license for the South Korean market, representing 2% of global NSAID demand. This arrangement includes US$10 million in milestone payments and a double-digit royalty.
ATB-352
Our second pipeline drug, ATB-352, targets the urgent global need for a non-addictive analgesic for severe pain, particularly in the post-operative setting, where many opioid addictions begin.
ATB-352 causes negligible GI damage in rats compared to ketoprofen, a very strong NSAID used for acute pain.
ATB-340
Our third pipeline drug, ATB-340, is a gastrointestinal-safe derivative of aspirin for daily use in the prevention of cardiovascular disease and cancer.
Aspirin, but not ATB-340, causes significant bleeding in the rat stomach.
Science
Antibe’s drug platform reflects two decades of research by our founder and Chief Scientific Officer, Dr. John L. Wallace, and his colleagues in laboratories around the world. Our research program is overseen by Scientific and Clinical Advisory Boards, comprising fourteen internationally renowned scientists and clinicians, with specialties in pharmacology, gastroenterology, cardiology, and a range of inflammation-based diseases. Antibe strives for the most rigorous level of scientific validation—clinical trials for our lead drug have involved more than 700 participants, including 360 patients across 40 clinical sites in the current Phase 2B dose-ranging, efficacy study.
Our Vision
Beginning with our family of NSAIDs, we are building a broad drug pipeline, expanding beyond pain and inflammation to include gastrointestinal and aging-related diseases—fulfilling our vision for improving health and quality of life for billions of people.
Our Management Team
Antibe’s senior team is based in Toronto, Canada. We are supported by a global network of advisors and subject matter experts covering scientific, clinical and regulatory affairs, investor relations and business development.
