Antibe Therapeutics

The mechanism of action of Antibe's drugs is the delivery of minute amounts of hydrogen sulfide to sites of inflammation within the human body.[3] Hydrogen sulfide has been shown to enhance the resolution of injury and repair of damage arising from tissue inflammation.[4] Antibe's lead drug, ATB-346, is a hydrogen sulfide-releasing derivative of naproxen, a commonly used non-steroidal anti-inflammatory drug (NSAID). ATB-346 is being developed to address osteoarthritis, although Antibe intends to broaden its application to rheumatoid arthritis and other diseases now treated with NSAIDs. Unlike standard naproxen, ATB-346 does not induce damage to the gastrointestinal tract.[5]

In May 2014, the company announced that it had completed pre-clinical studies on ATB-346.[6] In late June 2014, following approval from Health Canada, the company announced the first human dosing for Phase I of its human clinical trials.[7] In mid-January 2015, the company announced that clinical trials for its first drug were being suspended due to safety concerns; clinical trials were restarted in March 2015.[8]

On March 20, 2018, Antibe Therapeutics announced successful results for Phase 2B Gastrointestinal Safety Study for its lead pain drug, ATB-346. On March 30, 2019, the company launched its final Phase 2B trial for ATB-346.

Antibe's products have not yet been approved by the US Food and Drug Administration.
