Sweeping in behind Novavax Inc.’s positive phase III COVID-19 vaccine data is Johnson & Johnson’s single-shot COVID-19 vaccine, which met all the primary endpoints and key secondary endpoints in its phase III study, according to an interim analysis that found it to be 85% effective overall in preventing severe disease.
LONDON – A fourth COVID-19 vaccine is on the road to approval in Europe, with Novavax Inc. announcing positive interim data from the phase III U.K. trial of NVX-CoV2373. The vaccine was 89.3% effective at a time when there was a high rate of infection in the country, and in the face of the newly identified variant, B 1.1.7, which is more transmissible. There also was positive data, though slightly less sparkly, from a phase IIb study in South Africa, where NVX-CoV2373 showed 60% efficacy in preventing mild, moderate and severe COVID-19 disease.
In light of its ongoing restructuring of priorities, Medigene AG, of Planegg/Martinsried, Germany, is now discontinuing its MDG-1021 development program. The company was planning a phase I study of the T-cell receptor-modified T-cell (TCR-T) therapy that targets the antigen HA-1 in patients with relapsed or persistent blood cancers after allogeneic hematopoietic stem cell transplantation.
Marking the first time monoclonal antibodies developed by separate companies will be tested in combination against COVID-19, Vir Biotechnology Inc.’s VIR-7831 will be added to Eli Lilly and Co.’s bamlanivimab in the ongoing phase II BLAZE-4 study in low-risk patients with mild to moderate disease. The collaboration comes as early research indicates some antibodies in development appear to lose activity when pitted against emerging SARS-CoV-2 variants. VIR-7831 (also known as GSK-4182136), partnered with Glaxosmithkline plc, is designed to bind to a different epitope of the SARS-CoV-2 spike protein than bamlanivimab. A dual-action antibody, VIR-7831 is designed to both block viral entry into healthy cells and clear infected cells.
Phase II data with San Diego-based Heron Therapeutics Inc.’s pain drug HTX-011 (Zynrelef) graced the online pages of the Journal of the American Podiatric Medical Association in early January, whetting investor thirst for an FDA decision regarding approval, slated by May 12. And the agency’s go-ahead, if it comes, could have special meaning for Pacira Biosciences Inc. with competing analgesic Exparel (bupivacaine).

Regeneron Pharmaceuticals Inc. posted positive initial results from its ongoing phase III study of its monoclonal antibody cocktail, REGEN-COV (casirivimab and imdevimab), used as a passive vaccine, designed to provide immediate short-term passive immunity to prevent COVID-19 in people at high risk of infection due to household exposure to a COVID-19 patient. Eli Lilly and Co. reported upbeat news the same day, as the phase III Blaze-1 trial testing its antibody cocktail met its primary and key secondary endpoints.
