Twelve months after a single shot of Valneva SE’s chikungunya vaccine, positive antibody persistence was found, threatening a deadly disease that has long resisted treatment. The new data are derived from a study of 363 healthy adult participants that followed them from month 6 after vaccination to month 12. Nearly all, 99%, kept their neutralizing antibody titers for 12 months beyond the seroresponse threshold of 150, which hit the primary endpoint and the antibody level agreed with regulators as endpoint under the accelerated approval pathway.
The world is emerging from the COVID-19 pandemic, as both cases and deaths have remained consistently low in recent months, despite continuous mutation of the SARS-CoV-2 virus. Nevertheless, there is a shuffling of candidates in the arsenal as new variants bump once-effective therapies and the next generation of options enter the arena.
A diverse group of government and academic researchers, marking World AIDS Day 2022, have published details of an investigational vaccine they said safely induced broadly neutralizing antibody-precursors against HIV in nearly all participants in a small phase I trial.
While weekly global and U.S. confirmed cases of COVID-19 are below each of the last two years, infectious disease experts remain on guard. There are still about 1,500 people dying around the world each day, including 350 in the U.S., and the SARS-CoV-2 virus may continue to find ways to outmaneuver current treatments and vaccines.
CSL Ltd. subsidiary CSL Seqirus signed a licensing and development deal with Arcturus Therapeutics Inc. to in-license Arcturus’ late-stage self-amplifying mRNA vaccine platform technology. Arcturus will receive $200 million up front and is eligible to receive more than $1.3 billion in development milestones and over $3 billion in commercial milestones. In addition, it could capture a 40% net profit share for COVID-19 vaccines and up to double-digit royalties for vaccines against flu, pandemic preparedness and three other respiratory pathogens.
Pfizer Inc.’s bivalent prefusion vaccine for protecting newborns from severe respiratory syncytial virus (RSV) hit one of its two primary endpoints in its phase III study, which was good enough for the company to stop enrollment and plan to submit a BLA to the U.S. FDA by year-end. PF-06928316 is one of six RSV vaccines in active phase III development globally, which includes an Astrazeneca plc-Sanofi SA collaboration plus one from GSK plc. Pfizer’s is the only one developed for infants by way of maternal immunization and for older adults.
Sinocelltech Group Ltd. has reported positive interim data for two COVID-19 vaccine candidates, SCTV-01C and SCTV-01E, from phase III trials in the United Arab Emirates.
The White House laid out several timelines Oct. 18 as part of a national biodefense strategy for countering biological threats and enhancing global pandemic preparedness.
Differences in individual responses to COVID-19 vaccines have been linked directly to different human leukocyte antigen (HLA) alleles and it has been shown that people carrying one specific variant, HLA-DQB1*06, generate higher antibody responses and are better protected from SARS-CoV-2 infection.
PT Etana Biotechnologies Indonesia secured a series B financing of undisclosed value, led by Chinese investors that include Jack Ma’s Yunfeng Capital and Highlight Capital. The funds will be used to strengthen the company's pipeline and to expand its local manufacturing capacity.
