Products
PhD9 (anti-ricin monoclonal antibody candidate)
A monoclonal antibody developed as a therapeutic antidote to ricin exposure; plant-based manufacturing process and antibody have been studied in vitro and in vivo with results reported as comparable to mammalian-produced versions.
Recombinant butyrylcholinesterase (BuChE)
High-yield, plant-made recombinant BuChE being developed as a prophylactic and therapeutic countermeasure to organophosphate nerve agents (e.g., sarin, soman); safety evaluated in animal models.
Recombinant human hemopexin (enzyme drug candidate)
Plant-produced recombinant human hemopexin being investigated to reverse lung and mitochondrial injury caused by toxic halogen exposure (chlorine gas) and potentially for complications of sickle cell disease; preclinical data cited.
Recombinant human ACE2 candidates (SARS-CoV-2 decoy proteins)
Plant-expressed recombinant human ACE2 candidates for potential prophylactic or early-stage treatment of SARS-CoV-2 infection; program supported under contract with Defence Research and Development Canada with activities to express, purify and characterize ACE2 candidates.
