A qualitative assessment of the challenges of WHO prequalification for anti-malarial drugs in China

BACKGROUND: While China is a major manufacturer of artemisinin and its derivatives, it lags as a global leader in terms of the total export value of anti-malarial drugs as finished pharmaceutical products ready for marketing and use by patients. This may be due to the limited number of World Health Organization (WHO) prequalified anti-malarial drugs from China. Understanding the reasons for the slow progress of WHO prequalification (PQ) in China can help improve the current situation and may lead to greater efforts in malaria eradication by Chinese manufacturers. METHODS: In-depth interviews were conducted in China between November 2014 and December 2016. A total of 26 key informants from central government agencies, pharmaceutical companies, universities, and research institutes were interviewed, all of which had current or previous experience overseeing or implementing anti-malarial research and development in China. RESULTS: Chinese anti-malarial drugs that lack WHO PQ are mainly exported for use in the African private market. High upfront costs with unpredictable benefits, as well as limited information and limited technical support on WHO PQ, were reported as the main barriers to obtain WHO PQ for anti-malarial drugs by respondents from Chinese pharmaceutical companies. Potential incentives identified by respondents included tax relief, human resource training and consultation, as well as other incentives related to drug approval, such as China’s Fast Track Channel. CONCLUSIONS: Government support, as well as innovative incentives and collaboration mechanisms are needed for further adoption of WHO PQ for anti-malarial drugs in China.
