Tetra Bio-Pharma Provides Update on Market Potential for QIXLEEF

• Tetra Estimates Net Sales reaching $675M USD by 2027
• Tetra is evaluating potential commercial partners to launch QIXLEEF in USA

OTTAWA, ON / ACCESSWIRE / December 7, 2020 / Tetra Bio-Pharma Inc. ("Tetra" or the "Company") (TSX:TBP) (OTCQB:TBPMF), a leader in cannabinoid-derived drug discovery and development, today provided an update on the potential US market for QIXLEEF, a botanical cannabinoid-derived medicine that meets USA cGMP regulatory requirements. This botanical drug product composition has a fixed ratio of THC and CBD. The product is inhaled through a medical device (vaporizer) and will be first indicated in advanced cancer patients with inadequately controlled pain.

Based on a conservative market penetration and patient-based model, Tetra estimates potential net sales of $675M USD by 2027. Tetra is in the process of evaluating a potential strategic partner to run its commercial execution in USA. It is still premature to provide details on royalty level, upfront, and milestone payments.

Leading up to an expected Market Approval from the FDA in 2023 will be completion of the Phase II trial in 2021, Phase III trial in early 2022 and New Drug Application (NDA) submitted in 2022. Market Approval typically follows 9-10 months following NDA submission.

The patient-based model assumes that Tetra will secure a market approval from the FDA for its QIXLEEF in advanced cancer patient with inadequately controlled pain with a launch late 2023. Tetra also assumes that the QIXLEEF kit (QIXLEEF and its accompanying medical vaporizer) will be reimbursed by Health Maintenance Organizations (HMO). Our forecast also reflects the second planned indication in breakthrough pain which should follow soon after our first NDA through a supplemental marketing approval application (supplement to New Drug Application; sNDA). Our forecast remains conservative as it does not reflect potential opioid sparing usage.

Finally, QIXLEEF safety have been established through traditional dose escalation Phase I trials and an in-depth study of the composition of inhaled volatile organic compounds. In addition, the NDA will be supported with data on the metabolite profile, pharmacokinetics, pharmacodynamics and exposure to neutral and acidic forms of phytocannabinoids. Tetra is currently running a Phase II trial in the USA called PLENITUDE© and preparing the European Phase III trial.

Dania Scott, Senior Vice President, Commercial Strategy commented, "Tetra is leading the way with inhalation cannabinoid therapy in an ever-evolving therapeutic space. There are no precedents to follow in the pharmaceutical industry. QIXLEEF proprietary safety and dosing data, and fast acting effect can alleviate crippling pain for patients in need of immediate relief. Tetra believes that QIXLEEF has the potential to enable patients to significantly reduce their use and dependence on opioids. QIXLEEF therapeutic potentials and its addition to physicians' armamentarium will help evolve the quality of life for patients and their caregivers."
