Medicago submits Phase 3 data to Health Canada for its plant-based COVID-19 vaccine candidate


Final portion of data submitted as part of New Drug Submission for COVID rolling review

COVID-19 vaccine candidate fully developed in Canada submitted for authorization


QUEBEC CITY--(BUSINESS WIRE)-- Medicago, Inc. a biopharmaceutical company headquartered in Quebec City, is pleased to announce submission of the positive Phase 3 data for regulatory review by Health Canada as part of the New Drug Submission for COVID (NDS-CV) rolling review for Medicago’s COVID-19 vaccine candidate combined with GSK’s pandemic adjuvant. Medicago is seeking review and approval for the vaccine candidate for indication in healthy adults, aged 18 years and above.

“We are pleased to submit our Phase 3 data as the final portion of the rolling submission for our COVID-19 vaccine candidate for review,” said Dr. Judith Atkins, Vice-President of Regulatory Affairs at Medicago. “We are grateful to Health Canada for their review, and we hope this brings Canadians and the world one step closer to having greater vaccine diversity.”

Thomas Breuer, Chief Global Health Officer, GSK, added: “We are one step closer to our goal of making this innovative adjuvanted, plant-based vaccine available. As a refrigerator-stable option that builds on our established adjuvant technology, we are hopeful it will play an important role in the efforts to overcome the COVID-19 pandemic.”

The New Drug Submission for COVID (NDS-CV) process allowed the submission of nonclinical sections, quality, clinical safety, and efficacy information as they became available for Health Canada’s immediate review to accelerate the overall review process. Submitting the Phase 3 data completes the submission process.

The regulatory filing process for the COVID-19 vaccine candidate has been initiated with the FDA (US) and MHRA (UK). Preliminary discussion is underway with the WHO for preparation of the submission. A Phase 1/2 trial has also been initiated in Japan where Medicago plans to submit for regulatory approval in combination with the Phase 2/3 global study results next spring. The vaccine candidate has not yet been approved by any health authorities.

“If authorized, Medicago’s COVID-19 vaccine would be the world’s first ever plant-based vaccine approved for human use,” said Takashi Nagao, CEO and President of Medicago. “It would also be the first Canadian vaccine approved in over 20 years, signaling a powerful step forward for Canada’s vaccine preparedness strategy.”
