Our industry’s response to COVID-19 defied the conventional wisdom that it takes years to deliver new drugs. Makers of monoclonal antibodies led the pack, most notably Regeneron (NSDQ:REGN), which manufactured the 8-g, two-antibody cocktail administered to then-President Donald Trump last fall. Eli Lilly (NYSE:LLY) and Vir Biotechnology (NSDQ:VIR) pulled off similar feats. Prior speed records…
Novel COVID-19 vaccine could offer broad immune responses across SARS-CoV-2 variants
The emerging biotech Gritstone Bio (NSDQ:GRTS) has dosed the first patient with its second-generation COVID-19 vaccine known as GRT-R910. The University of Manchester and Manchester University NHS Foundation Trust are jointly overseeing the U.K.-based Phase 1 study. The GRT-R910 vaccine uses self-amplifying mRNA (SAM), which could optimize antigen expression at lower doses relative to conventional…
How Delta could change the COVID-19 landscape
Delta is “an extremely transmissible variant and has taken us all for a loop,” said Dr. Monica Gandhi, a professor of medicine and associate division chief of the division of HIV, infectious diseases and global medicine at University of California, San Francisco. But despite Delta’s hurricane-like ascent, the volume of infections it drives are likely…
Moderna’s COVID-19 vaccine holds its own against Delta variant in study
A small study indicated that Moderna’s messenger RNA COVID-19 vaccine was effective against the Delta variant. Using serum samples from eight Phase 1 participants drawn one week after administering the second dose of the vaccine, the analysis found a 2.1-fold reduction in neutralizing titers against the Delta (B.1.617.2) variant relative to the ancestral strain of…
HHS halts distribution of Lilly’s bamlanivimab/etesevimab antibody cocktail
U.S. government authorities have decided to immediately pause the distribution of Eli Lilly’s bamlanivimab and etesevimab over concerns that the monoclonal antibody cocktail is ineffective against some SARS-CoV-2 variants. CDC recently concluded that the Gamma variant (P.1) and the Beta variant (B.1.351) make up 11% of COVID-19 infections. They are also continuing to become more…
COVID-19 vaccinations continue to decline in the U.S.
The pace of COVID-19 vaccination in the U.S. continues to fall. Today, the U.S. administered about 600,000 COVID-19 vaccine doses, which is far fewer than two months ago. At the mid-April peak, healthcare workers administered more than 3 million COVID-19 vaccine doses. The pace of vaccination fell steadily from that time to early June before…
