LONDON – Delaying the second dose of Pfizer Inc./Biontech SE’s COVID-19 vaccine significantly increases the antibody response in people ages 80 to 99, compared to the approved schedule of two doses three weeks apart, according to the latest data from the U.K. coronavirus immunology consortium.
LONDON – Initial results from the U.K. randomized trial assessing mixed COVID-19 vaccine schedules show there is a significant increase in systemic side effects with one dose of Astrazeneca plc’s and one of Pfizer Inc./Biontech SE’s vaccines (in either order), compared to receiving two doses of the same vaccine.
A cautious optimism pervaded the March 11 Senate Health, Education, Labor and Pensions (HELP) Committee update on COVID-19, with witnesses and lawmakers alike welcoming the continuing decline of infections, hospitalizations and deaths in the U.S.
LONDON – A single dose of Pfizer Inc./Biontech SE’s COVID-19 vaccine does not promote a strong enough immune response to provide protection against variants of SARS-CoV-2, including the Kent variant B.1.1.7, which as of April 29 had caused 226,635 confirmed infections in the U.K.
Astrazeneca plc followed up its win a year ago in heart failure (HF) with yet another approval for its oral SGLT2 inhibitor, Farxiga (dapagliflozin), now cleared by the FDA to reduce the odds of kidney function decline, failure, cardiovascular death and hospitalization for HF in adults with chronic kidney disease (CKD) at risk of disease progression.
LONDON – The latest tranche of data from an array of large-scale COVID-19 studies running in the U.K. provides real-world evidence that vaccines have a dramatic effect in preventing hospitalization and death, but that there are a very small number of vaccine failures. The data cover 3,842 people who received a vaccine and subsequently were admitted to the hospital between Dec. 8, 2020, when the national vaccination rollout began, and the data cutoff of April 10, 2021.
LONDON – A large scale U.K. study looking at the impact of COVID-19 vaccinations on antibody responses and new infections in 373,402 people in the general population has shown a single dose of vaccine cut infections by 65%.
Astrazeneca plc’s saga of its COVID-19 vaccine continued this week with the European Commission (EC) deciding to begin legal action against the Cambridge, U.K.-based company, claiming it has failed to deliver doses in line with its contract.
Respiratory syncytial virus, which puts millions of otherwise healthy infants in the hospital each year, could soon face a new foe. Top-line results from a phase III test of the extended half-life monoclonal antibody nirsevimab, developed by Astrazeneca plc and Sanofi SA, found it reduced lower respiratory tract infections requiring medical attention due to the virus in both healthy preterm and term infants.
As part of a U.S. FDA evaluation of confirmatory trials for anti-PD-1/PD-L1 antibodies, the agency’s Oncologic Drugs Advisory Committee (ODAC) is being asked this week to consider whether three blockbuster biologics should continue to be available for certain cancer indications for which they received accelerated approval. At question is whether the data from the confirmatory trials for the Roche Group’s Tecentriq (atezolizumab), Merck & Co. Inc.’s Keytruda (pembrolizumab) and Bristol Myers Squibb Co.’s Opdivo (nivolumab) has proved sufficient benefit in particular indications and, if not, whether alternative or ongoing trials could do so.
