China FDA approves country’s first all-oral regimen for chronic hepatitis C, Daklinza in combination with Sunvepra

Daklinza and Sunvepra combination approved for genotype 1b, the most common chronic hepatitis C (HCV) genotype in China; combination has a 91-99% cure rate.

In more than 60 countries, Daklinza is approved as part of a regimen with either Sunvepra or sofosbuvir. In China, Daklinza-based regimens provide a shorter treatment duration (12 or 24 weeks) compared to 48 weeks of treatment with previously approved regimens. The Daklinza and Sunvepra regimen is already approved by regulatory authorities in multiple countries across the Asia Pacific, Latin America, and Eastern Europe regions. Sunvepra is not approved in the US.

“The burden of HCV in China is extremely high, and now for the first time, we have an all-oral treatment option in the combination of Daklinza and Sunvepra, which is a significant step forward for patients and doctors alike,” said Hui Zhuang, a professor at the Beijing University Medical School and a member of the Chinese Academy of Engineering. “This new option helps to address many of the unmet needs for our HCV genotype 1b patients, and is also included in the latest edition of China’s HCV Prevention and Treatment Guideline.”

The approval is based primarily upon results of the first completed Phase III 036 trial of the Daklinza and Sunvepra regimen for HCV among Chinese patients, which was published in the November 2016 issue of the Journal of Gastroenterology and Hepatology. In the trial, 91% of genotype 1b patients who had been previously interferon-ineligible or interferon-intolerant achieved sustained virologic response (“SVR”, or cure) at post-treatment week 24. The cure rate was higher, at 99%, in patients without baseline NS5A resistance-associated variants.

“We are proud to build on our legacy, infrastructure and experience in treating viral hepatitis throughout Asia by bringing Daklinza-based regimens to patients in China,” said Murdo Gordon, executive vice president and chief commercial officer, BMS. “Beginning with our efforts to treat chronic hepatitis B, BMS has been committed to combating viral hepatitis in China for over a decade.”

HCV represents a significant public health burden in China and is now the fourth most commonly reported infectious disease countrywide, with an estimated 10 million people currently living with the disease. Until now, standard of care in China has been interferon- and ribavirin-containing regimens which have left some patient groups with unmet needs. The cure rate for interferon- and ribavirin- containing regimens varies in a number of recent Chinese studies. In CCgenos, a real-world observation study, the cure rate for interferon- and ribavirin- containing regimens among GT-1b naïve patients is 62.4%.

Karl Lintel, President of BMS (China) Investment Co. Ltd and the Sino-American Shanghai Squibb Pharmaceutical Co., commented: “Today’s approval of Daklinza and Sunvepra is great news for patients in China, as we continue the global fight against chronic hepatitis C. This milestone is testament to our ongoing collaboration with multiple stakeholders, and aligning with government policies to provide continuing support to HCV patients at the community level.”
