QUEBEC - A Canadian biopharmaceutical company says it has received promising early test results for its plant-derived vaccine for COVID-19.
Privately held Medicago says interim results of a Phase 1 clinical trial found that 100 per cent of subjects developed an antibody response after two doses of its COVID-19 vaccine candidate.
“These are very promising results," said Nathalie Landry, Medicago's executive vice-president of scientific and medical affairs in a news release.
"We also observed that the antibody levels were higher after vaccination than those observed in convalescent sera from people who recovered from the disease.”
The Quebec City-based company says the side-effects were generally mild to moderate and short in duration.
The Phase 1 clinical trial was a randomized, partially blinded study of 180 healthy people.
Based on the Phase 1 data, Medicago plans to proceed with a Phase 2/3 clinical trial for its COVID-19 vaccine candidate, subject to regulatory approval.
The news comes a day after stock markets worldwide rallied on a report from Pfizer that a potential COVID-19 vaccine it's developing with German partner BioNTech may be 90 per cent effective, based on early but incomplete test results.
The federal government has signed a deal with Medicago to secure the rights to buy 76 million doses of its vaccine.
Medicago will also receive $173 million in funding from Ottawa for its vaccine research and development and for the construction of its Quebec City manufacturing facility.
