In addition to safety questions about its COVID-19 vaccine, Johnson & Johnson is facing manufacturing challenges as a key partner, Emergent Biosolutions Inc., has yet to get FDA approval to manufacture or distribute the vaccine or its components in the U.S. That approval could be awhile in coming. On April 21, a day after completing its onsite inspection of Emergent’s Bayview plant in Baltimore, Md., the FDA released Form 483 from its inspection, revealing nine observations related to cross-contamination issues, lack of employee training and poorly designed and maintained facilities.
LONDON – The EMA’s safety committee has concluded that unusual blood clots with low blood platelets are a rare side effect of Johnson & Johnson Inc.’s COVID-19 vaccine and that a warning should be added to the label. The decision is based on all available evidence, which currently consists of eight reports from the U.S. of serious cases of thrombosis, one of which was fatal. All cases were in people under 60 years of age, and within three weeks after vaccination, the majority in women. One case occurred during the clinical trials.
As COVID-19 deaths across the globe top 3 million, with more than 1 million in Europe alone, the global demand is increasing for mRNA vaccines, even as sponsors of adenovirus vaccines push back against ongoing safety concerns. Last week, the World Health Organization’s (WHO) Regional Office for Europe reported that the confirmed COVID-19 death toll for the region had surpassed 1 million, with 1.6 million new cases being reported every week. More than 171 million doses of COVID-19 vaccines have been administered in the region, translating to nearly 13% of the European population receiving one dose and close to 6% completing both doses of the vaccines.
DUBLIN – A newly published retrospective analysis of the electronic health care records of more than 500,000 COVID-19 patients has found that infection with SARS-CoV-2 carries “a significantly and substantially” greater risk of cerebral venous thrombosis (CVT) than does either one of the two approved mRNA COVID-19 vaccines or infection with influenza virus.
The current pause on administering Johnson & Johnson’s (J&J) one-dose COVID-19 vaccine likely will continue in the U.S. after the CDC’s Advisory Committee on Immunization Practices (ACIP) declined to make a recommendation on a path forward April 14.
LONDON – The U.K. is moving on to the next phase of testing mixed dosing schedules for COVID-19 vaccines, launching a study in which it will assess the effect of using Moderna Inc. or Novavax Inc.’s products as the second dose in a heterologous prime boost trial.
The FDA and the CDC have jointly recommended a temporary pause in the further rollout of Johnson & Johnson Co.’s COVID-19 vaccine while they investigate six rare clotting cases in adults ages 18 to 48.
LONDON – C4X Discovery Holdings plc has out-licensed its preclinical oral interleukin-17 (IL-17) inhibitor to Sanofi SA in a potential €414 million (US$493.4 million) deal. Under the terms of the agreement, Sanofi is paying €7 million up front and a further €11 in short-term preclinical milestones, with the balance to follow on reaching development, regulatory and commercialization milestones.
Among a spate of COVID-19-related therapy developments to start the week, Kiniksa Pharmaceuticals Inc. produced positive phase II data of its monoclonal antibody, mavrilimumab, in treating non-mechanically ventilated patients with severe COVID-19 pneumonia and hyperinflammation.
PERTH, Australia – The Australian government is recommending that Australians under 50 take the Pfizer Inc. COVID-19 vaccine due to the risk of rare blood clots associated with Astrazeneca plc’s COVID-19 vaccine (ChAdOx1-S). The move jeopardizes Australia’s vaccine rollout as it had planned for the majority of Australians to receive the Astrazeneca vaccine, which is being locally manufactured by CSL Ltd.
