BEIJING – Besides advancing its recombinant adenovirus type-5 vector (Ad5) vaccine for COVID-19, Cansino Biologics Inc. is making a new attempt to develop an mRNA lipid nanoparticle (mRNA-LNP) vaccine together with Canadian company Precision Nanosystems Inc., of Vancouver, British Columbia.

DUBLIN – Merck & Co. Inc. is placing two separate bets on recombinant viral vector technology in a broad effort to tackle COVID-19, in which it is also in-licensing a small-molecule antiviral drug. Kenilworth, N.J.-based Merck is acquiring Austrian vaccine developer Themis Bioscience GmbH in a move that propels the latter firm’s COVID-19 vaccine program to the front ranks of the industry pipeline. It is entering a COVID-19 vaccine development collaboration with the not-for-profit vaccine research organization IAVI.

LONDON – Human challenge specialist Open Orphan plc has raised £12 million (US$14.6 million) in a placing to accelerate development of COVID-19 challenge study models, to meet demand from vaccines and therapeutics developers worldwide.

Scaling up to manufacture a massive volume of a COVID-19 vaccine, drug or innovative device that’s still in early stage development is easier said than done, especially in a global pandemic that has the supply chain stretched beyond capacity.

LONDON – Astrazeneca plc is to get up to $1.2 billion from the new U.S. COVID-19 vaccines program, Operation Warp Speed, to support further development and manufacturing of a vaccine developed at Oxford University’s Jenner Institute. The company said it will begin to ship the product in September 2020, with the U.K. and U.S. first in line for deliveries.

Moderna Inc.’s chief medical officer, Tal Zaks, said that the results in hand “give us great confidence that we've got the right dose range for phase III” work slated to begin this summer with COVID-19 vaccine prospect mRNA-1273. A regulatory filing could come as early as 2021.

“Our window of opportunity is closing. If we fail to develop a national coordinated response, based in science, I fear the pandemic will get far worse and be prolonged, causing unprecedented illness and fatalities,” Rick Bright, former director of the Biomedical Advanced Research and Development Authority, said today as he testified at a House subcommittee hearing on the U.S. response to COVID-19.
