First ever clinical trial using pharmaceutical grade cannabis medication for use in managing uncontrolled cancer pain due to advanced cancer

QIXLEEF™ has the potential to transform the pain market

OTTAWA, ON / ACCESSWIRE / May 11, 2021 / Tetra Bio-Pharma Inc. ("Tetra" or the "Company") (TSX:TBP)(OTCQB:TBPMF)(FRA:JAM1), a leader in cannabinoid-derived drug discovery and development announced today the acceleration of a revolutionary Phase 2 clinical trial, PLENITUDE©, to evaluate the safety and efficacy of the investigational cannabis medicine, QIXLEEF™, for use in managing uncontrolled pain in patients with advanced cancer.

QIXLEEF™ is the Company's inhaled proprietary drug formulation which has a fixed ratio of THC and CBD. The medication is inhaled through a Class II medical vaporizer. When pharmaceutical grade cannabis is vaporized rather than smoked, the beneficial components can be inhaled without the generation of smoke and combusted by-products.

Dr. Guy Chamberland, CEO and CRO comments, "The PLENITUDE© study has been underway for many months and we are now accelerating its enrollment activities. Tetra currently has two Phase 2 clinical trials ongoing in the United States. Though both trials, PLENITUDE© and REBORN1©, will evaluate QIXLEEF™, each has a very different objective. The PLENITUDE© trial will assess how QIXLEEF™ may manage uncontrolled cancer pain in patients living with advanced cancer and the REBORN1© trial is a head-to-head study against an opioid treatment in the management of short and frequent episodes of incapacitating pain requesting immediate release opioid treatment in cancer patients. We believe based on our years of research that QIXLEEF™ will be proven to be safe and effective, and if so, provide patients with cancer pain a safer treatment option with potentially greater benefits than the current standard of care."

The PLENITUDE© trial is a four-week randomized, double-blind, placebo-controlled study and has been reviewed by an ethics committee and follows Good Clinical Practices. Patients will receive four weeks of either the study treatment or a placebo, after which all patients will be eligible to receive the active study drug for up to an additional 48 weeks. Pain levels will be measured throughout the course of the study to determine the efficacy of the study medication.

Dr. Sue Sisley, Medical Expert and Principal Investigator states, "The goal of the PLENITUDE© study is to help patients with advanced cancer manage their pain to improve their overall quality of life. I am excited about this study because it offers hope to patients who experience severe pain. Many patients have difficulty tolerating powerful therapies, like opioids. I am encouraged because cannabis has been long considered a low-risk option for patients with cancer with few and tolerable side effects. Together we may discover a new treatment option for managing pain!"

About Advanced Cancer Pain

Advanced cancer pain is defined by the International Association for the Study of Pain as "unpleasant sensory and emotional experience associated with actual or potential tissue damage". Pain is a common symptom associated with a cancer diagnosis. Market studies performed on behalf of Tetra for advanced cancer pain in the United States estimate that the addressable market will be worth over USD$900 million by 2030. This figure takes in consideration the off-label market, which will continue to demand non-opioid treatments.
