13 INHALED ANTI - COVID - 19 NANOAB PROTECTED HAMSTERS FROM SEVERE DISEASE Significantly milder disease course measured by weight loss in hamsters infected with SARS - COV - 2 and then treated with inhaled anti - COVID - 19 NanoAbs, administered 24 hours post infection, compared to placebo Highly statistically significant difference ( p<0.001 ) Inhaled NanoAb group ’ s weight declined on average only 4.1 % ( 0.2 mg doses) Placebo group’s weight declined on average 12.01% Study design: Hamsters were infected on Day 0. Treatment regimen of inhaled NanoAb twice daily for five days beginning on Day 1. Weight as a proxy for efficacy : According to the paper titled Hamsters as a Model of Severe Acute Respiratory Syndrome Coronavirus - 2 , hamsters are “ an ideal animal model of SARS - CoV - 2 infections because they recapitulate many aspects of human infections. ” The paper noted that weight loss in hamsters was reduced when treated with REGN - COV - 2 , a human mAb combination therapy that ultimately received FDA approval for SARS - CoV - 2 treatment.
