Beginning last month, Louisiana has been able to treat hundreds of patients who were waiting to receive a pricey cure for hepatitis C thanks to after hammering out an innovative payment model with a drug manufacturer, AIS Health reported.

But the road to get there was long and difficult, according to Rebekah Gee, M.D., secretary of the Louisiana Dept. of Health, who, during a July 22 event hosted by the Brookings Institution, detailed the challenges she faced in trying to get a costly curative therapy to more people while facing down a $2 billion budget deficit. “We were told ‘No’ at least 50 times from a variety of people, whether it was the industry, or policymakers or individuals at the CDC…because it had never been done before,” she said.

Here’s how the “modified subscription model” works: The state pays a fixed amount to Asegua Therapeutics LLC, a subsidiary of Gilead Sciences, Inc., for the authorized generic of Epclusa (sofosbuvir/velpatasvir tablets), up to a set spending cap, and in return gets unlimited access to the therapy for Medicaid beneficiaries.

For states that want to successfully replicate what Louisiana has done, not only do they need a solid partnership with CMS, but they must understand that price is not the only barrier to expanding treatment, said Neeraj Sood, a professor at the University of Southern California, who helped develop the model.
