Any fears that US Project Warp Speed had snubbed Glaxosmithkline and Sanofi were dispelled today. The companies – two of the world’s most important vaccine makers – revealed an award of up to $2.1bn for the development of a still unnamed Covid-19 product and delivery of an initial 100 million doses.
This brings to over $8bn the amount that Warp Speed, a partnership between the US Department of Health and Human Services, the FDA, the NIH, Barda and the Department of Defense, has committed towards vaccines against the coronavirus. Only three of the projects have generated human data, and two are not yet even in the clinic.
That should change soon, however. The Glaxo/Sanofi project is slated to start clinical trials in the second half of the year, a timeline the companies updated today: a phase I/II study will begin in September, followed by a pivotal trial by the end of 2020, and possible US approval “in the first half of 2021”.
And, while up to half of the $2.1bn award is pegged to the delivery of 100 million doses, and thus will not be paid until development is complete and the vaccine is manufactured, there is also an option for the US government to buy another 500 million doses later.

The Glaxo/Sanofi vaccine project has yet to be named, but it is known to be based on recombinant protein technology. Sanofi has a separate tie-up with Translate Bio covering an mRNA vaccine, and this is expected to enter phase I studies by the end of the year.
Also yet to generate clinical data are two other major Warp Speed funding recipients: Johnson & Johnson’s adenovirus-based project coded Ad26.COV2-S, and Novavax’s nanoparticle vaccine NVX-CoV2373. First human data from the latter, due in early August, now comprise one of the most eagerly awaited events for Covid-19 vaccine watchers.
Johnson & Johnson, meanwhile, yesterday confirmed that Ad26.COV2-S had entered phase I/IIa, and should move into phase III in September. This 30,000-subject study will comprise part of a pivotal effort that could see 180,000 people enrolled into trials of six Covid-19 vaccines by the end of this year.
Merck & Co
And a separate global vaccine player, Merck & Co, today provided some more information on two vaccines it is developing against the coronavirus.
V590, a recombinant vesicular stomatitis virus project in collaboration with Iavi, and V591, based on a measles virus vector technology and acquired along with Themis in May, should both be in the clinic this year. It seems that the Themis project is slightly further ahead in development, though it is the Iavi asset that is the beneficiary of a small Barda award of $38m.
The Glaxo/Sanofi vaccine also started out with a relatively small grant from the US government, namely $31m in April. Given that the budget for Project Warp Speed has never been disclosed, and neither has the number of possible beneficiaries, further awards are possible.
