I imagine Incepta might have found this link helpful when in their ledipasvir quest:
In addition,it appears Incepta has very sophisticated R & D and production facilities.
During the course of the last couple of years the company has received accreditation from many other countries of the world and currently holds the following GMP certificates from their respective Ministry of Health.
European Union GMP Certificate
Turkey GMP Certificate
Yemen GMP Certificate
Kenya GMP Certificate
Democratic Republic of Congo GMP Certificate
Ethiopia GMP Certificate
Uganda GMP Certificate
I believe Dr. Gane is a "company" man,
spouting the "company" line,
in support of the "company" bottom line.
That "company" being Gilead...
That doesn't mean the manufacture of ledipasvir isn't complicated. I'm sure it is.
