Fierce Biotech: GigaGen’s polyclonal antibody against COVID-19 outperforms plasma in lab tests


Blood collected from survivors of COVID-19 has been used to identify antibodies against the disease, which have been turned into experimental drugs to fight it. But it’s not an easy process. So back in March, San Francisco startup GigaGen decided to test a technology it developed to rapidly identify disease-fighting antibodies against SARS-CoV-2, the virus at the heart of the pandemic, and turn them into a drug to fight the disease.

Now the company says it has early evidence that the approach has yielded a promising drug candidate, GIGA-2050. When tested against the SARS-CoV-2 live virus, GIGA-2050 was 100 times more protective than plasma from survivors, they reported on the journal preprint site bioRxiv.
