Tetra's PPP004 cannabinoid drug receives Orphan Drug Designation for the Treatment of Epidermolysis Bullosa

OTTAWA / ACCESSWIRE / April 16, 2020 / Tetra Bio-Pharma Inc. ("Tetra" or the "Company") (TSX-V:TBP);(OTCQB:TBPMF), a leader in cannabinoid-derived drug discovery and development, is pleased to announce that it has received U.S. Food and Drug Administration (FDA) Orphan Drug Designation for its cannabinoid PPP004 (THC-CBD) in the treatment of epidermolysis bullosa.

Epidermolysis bullosa is a group of rare diseases that cause fragile, blistering skin and is associated with significant pain and reduced quality of life. Patient management is based on lifestyle changes and home care. If unsuccessful in the control of the signs and symptoms of this disease, further treatment will include medications, surgery and rehabilitation. Epidermolysis bullosa is a condition that commonly progresses despite treatment and can cause serious complications and death.

PP004 will be used for management of pain and itch in EB, symptoms that, despite a range of current treatment strategies, significantly affect the quality of life and activities of daily living among EB patients "Our preclinical research was completed for taking PPP004 into human clinical trials. We have a vast experience in the development of topicals with the recent completion of two clinical trials with AwayeÔ and expect to rapidly bring this product into trials. In the coming days, we will be reaching out to physicians specialized in the treatment of this disease to discuss a potential proof of concept clinical trial," commented Dr. Melanie Kelly CSO, Tetra Bio-Pharma Inc.

"We are very pleased to have received this new Orphan Drug Designation (ODD) from the FDA. Orphan designation qualifies PPP004 for development incentives that include tax credits for clinical trials, 7-years of marketing exclusivity and the marketing application (505(b)(1) NDA application) is not subject to prescription drug user fees. These incentives are critically important to a small biopharma," said Dr. Guy Chamberland, CEO and Chief Regulatory Officer of Tetra Bio-Pharma. Dr. Chamberland further added, "Tetra will be assessing to launch a proof of concept trial in the coming months and will be requesting a Type B meeting with the US FDA to discuss the marketing requirements for this Orphan Drug indication. The Company will provide an update to share holders once the meeting is confirmed."
