First results from the U.K. Cov-Boost trial, looking at responses to a fourth dose of an mRNA COVID-19 vaccine, show that antibody levels increase more than after the third dose, confirming the precautionary move to give the most vulnerable a second COVID-19 booster in advance of immune response data being available.
The U.S. FDA’s efficacy bar for COVID-19 vaccines for the youngest children may be lower than the 50% required for the adult vaccines, according to Peter Marks, director of the agency’s Center for Biologics Evaluation and Research.<
Shares in Bavarian Nordic A/S fell sharply after its development partner Johnson & Johnson terminated collaboration and license agreements in hepatitis B virus (HBV) and human papillomavirus (HPV). Shares in the Danish company (OMX:BAVA) fell nearly 13% to DKK 115.75 (US$16.39) following the announcement. The partnerships, with J&J’s Janssen pharma unit, began with a $187 million tie-up in 2014, to develop an Ebola vaccine that is now approved in the EU. That led to an $171 million HPV vaccine research agreement in December 2015 and an $879 million deal covering HIV-1 and HBV research in 2017.
A risk of rare but potentially life-threatening blood clots in combination with low platelet levels after a jab of Johnson & Johnson's Janssen COVID-19 vaccine has convinced the U.S. FDA to limit its use. The vaccine is now authorized in the U.S. only for adults who wouldn't otherwise be vaccinated and those who can't or shouldn't, for medical reasons, get another approved vaccine. Through March 18, 2022, the FDA and CDC have identified 60 confirmed cases, including nine fatal cases of the condition, called thrombosis with thrombocytopenia syndrome – a rate of 3.23 cases per million doses of vaccine administered.
A proposal hammered out by the EU, India, South Africa and the U.S. to allow IP waivers for COVID-19 vaccines is headed to all members of the World Trade Organization (WTO) for consideration.
For the first time since the early weeks of the COVID-19 pandemic in 2020, global deaths caused by the disease have fallen to their lowest point, as immunity against the SARS-CoV-2 virus and its variants continues to build. Infections and deaths appear to be decelerating, an optimistic sign that the pandemic may be nearing an end.
As many biopharmas rethink plans to go public on less-than-welcoming U.S. markets, Hillevax Inc. forged ahead, pricing an upsized IPO April 28, offering 11.8 million shares at $17 apiece, the midpoint of its previously proposed range, for gross proceeds of about $200 million. That’s the highest amount raised in a U.S. IPO so far in 2022, which saw only nine companies go public on Nasdaq during the first quarter.
Making his first in-person appearance April 27 before the House Energy and Commerce Subcommittee on Health, U.S. Health and Human Services Secretary Xavier Becerra was prepared to answer questions about President Joe Biden’s fiscal 2023 budget that would increase HHS’ discretionary budget to $127 billion, nearly a 27% increase over the 2021 enacted level.
Arcturus Therapeutics Holdings Inc. reported that ARCT-154, its self-amplifying mRNA COVID-19 vaccine, showed efficacy of 55% against infection and 95% efficacy against severe disease, meeting the primary and key secondary endpoints of the ongoing phase I/II/III trial. While the company’s stock (NASDAQ:ARCT) regained much of its initial 25% drop to close the day, investors continue to await further data to determine where Arcturus’ vaccine will fit in with available COVID-19 vaccines.
Shares in Valneva SE fell sharply after the company said European regulators came back with further queries, including on antibody efficacy data, instead of a recommendation during a rolling review of its delayed COVID-19 vaccine. The company had expected a positive opinion on the vaccine, known as VLA-2001, following the April meeting of the European Medicines Agency’s CHMP committee.
