Treating the hepatitis C virus used to require frequent injections and daily pills that had to be taken for up to a year with flu-like side-effects. Tolerable drugs that could eliminate the infection in most patients in about 12 weeks were introduced in 2013. But the retail price for an eight- to 24-week regimen of the anti-virals ranged from $55,000 to $80,000 in 2015. Now the non-profit organization Drugs for Neglected Diseases Initiative and Egyptian drug maker Pharco Pharmaceuticals have signed agreements to provide a combination of the Hepatitis C drugs sofosbuvir and the antiviral ravisdasvir for further clinical tests for $300 US or less per treatment course. The agreement was announced this week at the International Liver Congress ... said Dr. Isabelle Andrieux-Meyer, HIV and hepatitis C medical advisor for Doctors Without Borders. The drugs make such a difference in wealthy countries but the contrast in lower and middle income countries is "brutal," Andrieux-Meyer said. "So many patients can't buy treatment," she said. Under the agreement, the company agreed to set the commercial price at $294 US or less per treatment course once the scale-up is approved. Doctors Without Borders is a member of the Drugs for Neglected Diseases Initiative, which has licensed rights for ravisdasvir in low- and middle-income countries from Presidio Pharmaceuticals.
