The biopharma industry has started 2022 with plenty of clinical trial news. Here’s a look.


COVID-19-Related


Celltrion Group announced Phase I results from its antibody cocktail of Regkirona and CT-P63. One Phase I study tested CT-P63 in 24 healthy participants in Poland. The trial hit the primary objective of safety and tolerability. It also demonstrated strong neutralizing activity against the Omicron variant. CT-P63 is a monoclonal antibody that targets the SARS-CoV-2 spike receptor binding domain (RBD) and comes in a nebulized formulation. A second drug being investigated is CT-P59 (regdanvimab), which in studies has been shown to strongly bind to RBD and neutralize the wild type and mutant variations of concern. And in in vivo models, it has effectively decreased the viral load of SARS-COV-2 and lung inflammation. Regkirona is given intravenously.


Gritstone bio announced positive Phase I data from the first cohort of its CORAL-BOOST study. The study is evaluating a 10-microgram dose of CORAL self-amplifying mRNA vaccine.
