Instead of including the trial arm to an ongoing U.S. course of, a new research can be run to judge a decrease dosage that carried out higher than a full quantity in AstraZeneca’s research, Soriot mentioned in a Bloomberg News report.

“Now that we’ve found what looks like a better efficacy, we have to validate this, so we need to do an additional study,” Soriot was quoted within the report as saying.

Soriot mentioned it might in all probability be one other “international study, but this one could be faster because we know the efficacy is high so we need a smaller number of patients.”

The information comes as AstraZeneca faces questions on its success price that some specialists say might hinder its possibilities of getting speedy U.S. and EU regulatory approval.
