Novavax delays US trials for COVID vaccine and says late-stage study will begin ‘in coming weeks’
Novavax delays US trials for its coronavirus vaccine AGAIN and says late-stage examine will start ‘within the coming weeks’ because it struggles to scale up manufacturing of its jab
- Novovax delayed the beginning of its late-stage US trials for the second time after initially declaring a begin date in October after which November
- The corporate stated it had issues scaling up its manufacturing and plans to start ‘within the coming weeks’
- Late-stage trials have begun within the UK and in South Africa, with interim outcomes anticipated in early 2021
- Novavax’s vaccine makes use of synthesized items of the floor protein that the coronavirus makes use of to invade human cells and spurs antibody manufacturing
Vaccine maker Novavax stated on Monday it has pushed again the beginning of US trials for its experimental coronavirus vaccine and expects them to start ‘within the coming weeks.’
That is the second time the Maryland-based firm has rescheduled the beginning date of its late-stage Section III trials.
Novovax first flagged an October begin date, which was hampered by points in scaling up its manufacturing after which said it will start in November earlier than delaying but once more.
The agency plans to make use of vaccine materials produced at industrial scale for the trial within the US and Mexico and has been working intently with the US Meals and Drug Administration (FDA) to greenlight the usage of the vaccine made at a North Carolina plant.
In the meantime, Novovax has accomplished enrollment for its 15,000 participant UK trial and expects interim knowledge as quickly as the primary quarter of 2021.

Novavax, which has not produced a vaccine earlier than, created a shot that comprises synthesized items of the floor protein that the coronavirus makes use of to invade human cells.
The thought is that the protein will trigger human cells to spur manufacturing of antibodies to battle the an infection.
The inoculation, named NVX-CoV2373, was given with or with out an adjuvant, which is an agent that reinforces the immune response.
In early US trials, contributors have been break up into 4 teams and given 5 micrograms or 25 micrograms of the vaccine or the placebo with or with out the additional ingredient.
For individuals who have been immunized they got the jab by way of intramuscular injection about 21 days aside.
Researchers discovered that volunteers generated excessive ranges of neutralizing antibodies and T-cells, each of that are wanted to construct up immunity.
What’s extra, the degrees have been greater than these seen amongst sufferers who’ve recovered from COVID-19, the illness brought on by the virus.
Eight examine contributors skilled hostile unwanted side effects after receiving a second vaccine dose throughout the trial, though none required medical intervention, the corporate stated.
Headache, fatigue, and muscle ache have been among the many extra widespread unwanted side effects, and the vaccine was ‘nicely tolerated’ total, in keeping with a press release.
Novavax stated the addition of the adjuvant did improve the impact of the vaccine within the examine.
Presently, Novovax is working trials in 4 international locations, together with within the UK and South Africa.
Of the 15,000 contributors within the UK trial, greater than 25 p.c are over the age of 65, whereas a big proportion of volunteers had underlying co-morbid medical situations usually consultant of the inhabitants.
In South Africa, Novoax is working a fully-enrolled Section 2b trial, which has 4,400 volunteers, together with 245 who’re medically steady, HIV optimistic contributors.
Efficacy knowledge from that trial is also accessible within the first quarter of subsequent 12 months.
When late-stage trials start within the US, it will likely be the fifth coronavirus vaccine to take action, following Pfizer inc, Moderna Inc, AstraZeneca Plc and Johnson & Johnson.
In July, Novovax was awarded $1.6 billion from the federal authorities’s Operation Warp Pace to fund its Section III trial and to scale-up manufacturing.
