Tetra Bio-Pharma Inc. (TSX Venture: TBP) develops cannabinoid-derived biopharmaceuticals targeting inflammation, pain, ophthalmology, and oncology indications through clinical programs and prescription drug candidates for patients and healthcare providers. The company offers a pipeline of cannabinoid-based products including QIXLEEF, a botanical THC-CBD therapy for therapeutic uses; CAUMZ; PPP004 for painful dry eye and uveitis; REDUVO, a dronabinol soft gel capsule for chemotherapy-induced nausea, vomiting, and HIV-related weight loss; REBORN1 for breakthrough cancer pain and oral opioid alternatives; PLENITUDE for cancer-related pain; ARDS-003 for sepsis and acute respiratory distress syndrome prevention; SERENITY for cancer cachexia; and HCC011 for hepatocellular carcinoma, alongside veterinary products and natural health formulations; it employs advanced delivery systems, patented mechanisms, and rigorous clinical trials to meet pharmaceutical standards. Founded in 2008 and headquartered in Orleans, Ontario, Canada, with approximately 33 employees and subsidiaries such as Phyto Pain Pharma Inc., Panag Pharma Inc., and a former Australian entity, Tetra Bio-Pharma operates primarily in North America with past clinical trial partnerships in Australia. Recent major developments include a 2019 acquisition of Panag Pharma to bolster ophthalmic pain formulations; partnerships with Avicanna, Cellvera Global Holdings for ARDS-003/favipiravir COVID-19 combo, Ovensa for glioblastoma nanomedicines, and Cannvalate for Australian trials; financing such as C$6 million from Alpha Blue Ocean in 2019 and up to C$4.5 million Quebec loan; regulatory milestones like Health Canada NDS review for REDUVO, EMA orphan drug opinion for QIXLEEF, and U.S. mid-stage trial shipments; followed by a voluntary bankruptcy filing under Canada's Bankruptcy and Insolvency Act on August 1, 2023, with Houle Roy S.A. as trustee after Ontario Securities Commission rejection of a management cease trade order precluded further financing, leading to halted operations, delisting from TSX Venture, and OTC trading as TBPMQ/TBPMF.
