Medicago, a subsidiary in Canada
is tackling with COVID-19, coronavirus
Mitsubishi Tanabe Pharma Corporation (Head Office: Chuo-ku, Osaka; President &Representative Director; Masayuki Mitsuka) announced today that its affiliatedcompany, Medicago Inc. (Head Office: Quebec, Canada; CEO; Bruce D. Clark) has
successfully produced a Virus Like Particle (VLP) of the coronavirus responding
COVID-19.
Production of the VLP is the first step in developing a vaccine for COVID-19 which
will now undergo preclinical testing for safety and efficacy. Once such testing iscompleted, Medicago expects to discuss with the appropriate Health Agencies toinitiate human trials of the vaccine by summer (July/August) 2020.
In addition, Medicago is also using their technology platform to develop antibodies
against SARS-CoV-2 (virus causing the COVID-19 disease) in collaboration with
the Laval University’s Infectious Disease Research Centre. This research is being
funded, in part, by the Canadian Institutes of Health Research (CIHR)

FOR IMMEDIATE RELEASE
Medicago announces production of a viable vaccine candidate for COVID-19
The biopharma successfully produced Virus-Like Particles (VLP) of the coronavirus in just 20
days using proprietary plant-based technology
Medicago’s platform can produce both vaccine and antibody candidates against COVID-19 disease
QUEBEC CITY, March 12, 2020 - Medicago, a biopharmaceutical company headquartered in Quebec
City, announced today that they have successfully produced a Virus-Like Particle (VLP) of thecoronavirus just 20 days after obtaining the SARS-CoV-2 (virus causing the COVID-19 disease) gene.
Production of the VLP is the first step in developing a vaccine for COVID-19 which will now undergo
preclinical testing for safety and efficacy. Once this is completed, Medicago expects to discuss with theappropriate Health Agencies to initiate human trials of the vaccine by summer (July/August) 2020.
Medicago is also using its technology platform to develop antibodies against SARS-CoV-2 incollaboration with the Laval University’s Infectious Disease Research Centre headed by Dr. Gary
Kobinger who helped develop a vaccine and treatment for Ebola. These SARS-CoV-2 antibodies could
potentially be used to treat people infected by the virus. This research is being funded, in part, by theCanadian Institutes for Health Research (CIHR).
Medicago is a leader in plant-based technology having previously demonstrated its capability to be a first
responder in a flu pandemic. In 2009, the company produced a research-grade vaccine candidate against
H1N1 in just 19 days. In 2012, Medicago manufactured 10 million doses of a monovalent influenza
vaccine within one month for the Defense Advanced Research Projects Agency (DARPA), part of theU.S. Department of Defense. In 2015, Medicago also demonstrated that it could rapidly produce an antiEbola monoclonal antibody cocktail for the Biomedical Advanced Research and Development Authority(BARDA), part of the U.S. Department of Health and Human Services.
“The pace of our initial progress in COVID-19 is attributable to the capability of our plant-based platform
which is able to produce vaccine and antibody solutions to counteract this global public health threat. Theability to produce a candidate vaccine within 20 days after obtaining the gene is a critical differentiator forour proven technology. This technology enables scale-up at unprecedented speed to potentially combat
COVID-19.” said Dr Bruce Clark, CEO of Medicago.
Dr Gary Kobinger, Professor in the Department of Microbiology and Infectious Diseases and the Directorof the Infectious Disease Research Centre at Laval University, said “the collaborative efforts establishedbetween the research team at Laval University and Medicago have been very successful in developing
unique antibodies against infectious diseases such as RSV and HMPV and that experience gives usconfidence for successful identification of therapeutic antibodies against SARS-CoV-2”.

Medicago’s first product, a seasonal recombinant quadrivalent VLP vaccine for active immunization
against influenza, is currently under review by Health Canada following the completion of a robust safety
and efficacy clinical program involving over 25,000 patients.

Medicago’s unique plant-based platform
The company uses a proprietary plant-based technology to develop protein-based therapeutics. Unlike
traditional vaccination development, Medicago does not use animal products or live viruses to create its
products. Instead, it uses Virus-Like Particles (VLPs) that mimic the shape and dimensions of a virus,
which allows the body to recognize them and create an immune response in a non-infectious way.
Clinical trial data suggest that VLPs have a multi-modal mechanism of action that is different from that ofinactivated vaccines, activating both arms of the immune system – antibody and cell-mediated responses.
Medicago’s proprietary technology is rapid, versatile, and scalable. As soon as the genetic sequence of avirus is made available, Medicago can develop a clinical-grade vaccine candidate in only a few weeks.
Its recombinant technology allows the production of a vaccine that precisely matches the circulatingstrains, such as in the case of seasonal influenza. The technology is easily scalable, allowing thecompany to increase volume of production by simply increasing the number of plants it uses.

Product portfolio and pipeline
Medicago’s first product, a Recombinant Quadrivalent Virus-Like Particle (QVLP) seasonal flu vaccine ispresently under review by Health Canada. Vaccine candidates for pandemic flu, rotavirus and norovirus
are being tested across pre-clinical and Phase II clinical trials. Medicago is also developing antibodies
against hMPV, RSV and Opioids.

Facilities
Medicago is headquartered in Quebec City, Canada, and plans to produce COVID-19 vaccines andantibodies in its Quebec pilot plant to respond to the immediate short-term demand. The company also
has a manufacturing facility in Durham, North Carolina (USA), which is currently dedicated to theproduction of vaccines and antibodies for its clinical trials and is expected to support the launch of thequadrivalent VLP influenza vaccine once it is approved. A new state-of-the-art manufacturing plant isunder construction in Quebec City, which will be fully functional by 2023 and will have the capability todeliver up to 50 million doses of recombinant quadrivalent influenza vaccine per year.
