AQCH is derived from tropical, climbing shrub cocculus hirsutus, which is used in Asia for its apparent medicinal properties.
The company said the trial will be conducted across 12 centers in India in 210 patients and a human safety study of the drug has been completed.
“AQCH, which is being developed for dengue, has shown broad antiviral effect in in-vitro studies and hence is being tested as a potential treatment option for Covid-19,” the company said in a statement.
