Tetra Bio-Pharma Inc. (TBPMF) Initiates a Proof of Concept Clinical Trial for its Ophthalmic Drug in Dogs

On February 8^th 2020, Tetra Bio-Pharma, in partnership with a veterinary ophthalmology team, initiated recruitment of an in-life phase proof of concept clinical trial in companion dogs with complications of indolent corneal ulcers, with the first dog to be treated on February 21, 2020. This Health Canada approved trial is designed to evaluate the safety, tolerability and potential efficacy of PPP003v, the company’s synthetic cannabinoid therapy, to ameliorate symptoms of this painful eye disease in dogs. Canine indolent corneal ulcers occur frequently in specific breeds of dogs⁵. Corneal ulcers are one of the most common painful eye disorders seen by veterinarians and untreated can cause severe pain, inflammation, scarring and vision loss⁶.

PPP003v is Tetra’s proprietary veterinary ocular formulation for treating ocular pain and inflammation in companion animals.  PPP003v was developed and patented by Tetra’s Ophthalmic division and contains a non-controlled synthetic cannabinoid 2 receptor selective agent in an optimized formulation for topical delivery to the eye.  Extensive preclinical research has validated the Cannabinoid 2 receptor as a key drug target for reducing ocular inflammation and pain.^1-4

Tetra has previously carried out pre-clinical research confirming the efficacy of PPP003v for reducing symptoms of painful inflammatory eye disease. This study will be the first time a synthetic cannabinoid agent is used in companion animals with the goal of providing pet owners with an alternative ophthalmic pain medication. The veterinary health market was estimated at $17.3Bn in 2018 posting a robust CAGR of 4%⁷. This proof of concept clinical trial will be completed by April 30, 2020.

Based on positive results from this initial proof of concept clinical trial, Tetra will submit a new clinical trial application to the Veterinary Drugs Directorate of Health Canada to extend the findings of safety and efficacy for PPP003v, as well as commence regulatory filings of Veterinary New Drug Submission with Health Canada and New Animal Drug Application with the U.S. Food and Drug Administration to ensure that this drug will be available to the Canadian and U.S. markets for post operative eye pain.  Tetra is actively seeking interested partners to license its PPP0003v line for commercialization.

“The PPP003 program, including PPP003v, is an attractive opportunity for Tetra since there is a significant unmet medical need for painful inflammatory eye disease. The veterinary program and these animal studies will provide important data, which can potentially be included as part of the pre-clinical data necessary to support PPP003 use in human clinical trials,” said Dr. Guy Chamberland, CEO and CRO of Tetra BioPharma, “The choice of a non-controlled synthetic cannabinoid was specifically selected to allow for acceptance in markets globally. We are extremely pleased that the U.S. FDA validated our human ophthalmic research program enabling Tetra to launch our clinical development program in line with our projected milestones.”
