Between January 2009 and April 2016, 134 novel anticancer therapies were approved: what is the level of knowledge concerning the clinical benefit at the time of approval?

OBJECTIVE: In the last decade an increasing number of high-priced, new cancer treatments received marketing authorisation in Europe. What is actually known about the clinical benefit of those therapies at the time of approval needs to be elucidated in order to inform decisions about the use and reimbursement of these novel treatment options. Thus, the aim of the current analysis was to systematically investigate oncological therapies approved between January 2009 and April 2016 and extract as well as quantify the level of knowledge of the clinical benefit at the time of marketing authorisation. METHODS: To assess the benefit of new interventions as well as expanded indications, we extracted the median gain of the two study end points: progression-free survival (PFS) and overall survival (OS). Information is based on approval documents provided by the European Medicines Agency and assessments from the Austrian Horizon Scanning programme. We included all cancer therapies approved in Europe between 2009 (January 1) and 2016 (April 15). RESULTS: Cancer drugs for 134 new indications approved since 2009 were identified. In the case of 37 indications (27%), no data were available for PFS or for OS. A positive difference in median OS was reached by 76 licensed indications (55.5%); 22 (16%) of them showed a difference of more than 3 months. Regarding the study end point PFS, an improvement was shown in 90 indications (65.2%). CONCLUSION: Scarce knowledge regarding the clinical benefit of anticancer therapies is available at the time of approval. In addition, the survival benefit of the approved indications is less than 3 months in the majority of approved therapies.
