Delivering antibodies in the form of their DNA could enable their therapeutic use under several circumstances where traditional antibodies fall short. One of those is resource-poor settings where the current cost of antibodies makes them a nonstarter. Perhaps the largest opportunity to expand antibody use in such settings is for HIV, where broadly neutralizing antibodies have the potential to be the next best thing to a vaccine or a cure – if they can be made to last, for cheap.
Monoclonal antibodies are a triumph of modern medicine. They are also too expensive to be a standard therapy in all but the wealthiest countries. “Having 10% or 15% of your population on antibodies is not sustainable even in wealthy countries,” Rachel Liberatore told BioWorld. Liberatore is director of research and development at Renbio Inc., which is testing the intramuscular delivery of antibody-encoding DNA to prevent and treat infections, including SARS-CoV-2 and HIV.
Exevir Bio NV is honing its attack on the crowded market for COVID-19 antibodies, beginning clinical development of a potential subcutaneously administered drug targeting outpatients with early symptoms who are at risk of further progression.
Celltrion Inc. has bagged its first green light outside Asia for its COVID-19 monoclonal antibody Regkirona (regdanvimab) with an emergency use authorization in Brazil. Brazil’s Anvisa gave the EUA for the drug to treat high-risk adult patients, including those aged 65 or older, with mild and moderate COVID-19 symptoms on Aug. 11. The regulator reached its decision on the drug, also known as CT-P59, via a unanimous vote.

Shares of Humanigen Inc. (NASDAQ:HGEN) leapt 54.5% to $21.61 March 29 on news that its monoclonal antibody, lenzilumab, improved the relative likelihood of survival without mechanical ventilation in hospitalized patients with COVID-19, setting the company up to submit an application for emergency use authorization (EUA) in the U.S. "as soon as possible," it said. Separately, a combination of two monoclonal antibodies, the Eli Lilly and Co.-Abcellera Biologics Inc.-developed therapy bamlanivimab and the Vir Biotechnology Inc.-Glaxosmithkline plc candidate VIR-7831, demonstrated a 70% relative reduction in persistently high SARS-CoV-2 viral load at day seven compared to placebo for low-risk adult patients with mild to moderate COVID-19, the companies reported.
