Gilead attempt to secure patent on hepatitis C drug opposed in India

‘Patent opposition’ seeks to ensure production of affordable generics

New Delhi/New York, 22 November 2013—Médecins Sans Frontières (MSF) supports the ‘patent opposition’ just filed at India’s Patent Office by the Initiative for Medicines, Access & Knowledge (I-MAK), which aims to prevent US pharmaceutical company Gilead/Pharmasset from gaining a patent in India on sofosbuvir, a drug for hepatitis C that is coming to market soon with an anticipated exorbitant price.

Gilead is expected to charge around $80,000 for one treatment course of sofosbuvir in the US. Even if offered at a fraction of this price in developing countries, this drug will be priced out of reach. The patent opposition—a form of citizen review allowed in many countries—offers technical grounds to show a drug does not merit patenting under India's Patents Act. This opposition was filed to ensure that affordable generic versions of sofosbuvir can be produced to help the millions of people infected with chronic hepatitis C in developing countries access the drug. 
“Old science, existing compound,” said Tahir Amin, lawyer and director of I-MAK.org. “India’s patent law doesn’t give monopolies for old science or for compounds that are already in the public domain. We believe this patent on sofosbuvir does not deserve to be granted in India and have the legal grounds to prove it.”
Sofosbuvir is the first of several oral hepatitis C drugs expected to come to market in the coming year. It cures hepatitis C in a much shorter time period than today’s available treatment, and for some forms of hepatitis C, eliminates the need to use the injectable drug pegylated interferon, which can be difficult to administer and causes many serious side effects. Gilead is anticipated to receive marketing approval for sofosbuvir in the US on 8 December.
MSF has started providing hepatitis C treatment for a small number of people co-infected with HIV in its clinic in Mumbai, but cost (as high as $5,000 per patient) and complexity of today’s available treatment means that patient numbers remain extremely low despite considerable needs.
“In our projects, we need access to medicines like sofosbuvir that are easier for patients to take so we can expand treatment to more people. If the drug is unaffordable, the majority of the most vulnerable groups will remain untreated,” said Dr. Simon Janes, medical coordinator with MSF in India. “We know from our experience providing HIV treatment over more than a decade in dozens of developing countries that treatment needs to be simple and affordable—preferably less than $500 to start with. An unaffordable price for this drug will have a chilling effect on funders and governments who need to start financing and providing treatment.”
The World Health Organization estimates there are 184 million people infected with hepatitis C worldwide, with the disease causing half a million deaths each year. The vast majority of these people live in developing countries where—with the exception of Brazil and Egypt—there is no provision for universal access to hepatitis C treatment in public healthcare programmes.
“The world is waking up to a new crisis with hepatitis C,” said Olga Stefanishina of the Ukrainian Community Advisory Board. “More and more people are being diagnosed with chronic hepatitis C but are left to die because there’s no affordable treatment. With this patent opposition in India, we are starting the fight for better treatment that people can afford and governments can provide. We have no time to wait for charity or country-by-country negotiations—low cost generic drugs must be made available to all high-burden countries without discrimination.”
India has been called the ‘pharmacy of the developing world,’ because it produces many affordable generic versions of drugs patented elsewhere. More than 80% of the HIV medicines used in developing countries come from India, which is able to produce these medicines because its patent law sets the bar high for which medicines do and do not merit patenting, allowing generic manufacturers to compete for the market and drive prices down.
“The hepatitis C drugs coming out of the drug pipeline, including sofosbuvir, are compounds that are relatively simple and cheap to make,” said Dr. Andrew Hill, a pharmacologist at Liverpool University who has published a study showing that sofosbuvir could be produced for as little as US $62-$134 for a 12-week treatment course. “The profit projections for the oral hepatitis C drugs are staggering, and stand in no relation to what it costs to make these drugs.”
