Design, organisation and impact of treatment optimisation studies in breast, lung and colorectal cancer: The experience of the European Organisation for Research and Treatment of Cancer

Journal Contribution - Journal Article

BACKGROUND: Treatment optimisation studies (TOSs) are clinical trials which aim to tackle research questions that are often left unaddressed within the current drug development paradigm due to a lack of financial and regulatory incentives to undertake them. Examples include comparative effectiveness, therapeutic sequencing and dose de-escalation studies. Trials of this nature have historically been primarily carried out by academic institutions and not-for-profit organisations such as the European Organisation for Research and Treatment of Cancer (EORTC). OBJECTIVES: Our objective was to conduct an in-depth analysis of the breast, lung and colorectal cancer TOSs that have been performed by the EORTC in the past four decades. METHODS: We searched the EORTC clinical trials database for relevant studies and subsequently analysed them based on a number of predefined criteria relating to their design, organisation and scientific impact. RESULTS: The 113 EORTC TOSs examined in this analysis were mainly standard-sized, international, multicentre phase III trials using a relatively simple, randomised, open-label design and comparing pharmacological combination regimens against standard-of-care treatments in terms of their potential to improve overall survival of patients with cancer. Although they were typically financially and/or materially supported by the industry, their legal sponsor was nearly always an independent party that did not benefit monetarily from their outcomes. If meaningful findings were obtained, their results, regardless of whether positive or negative, were published in high-impact journals, and the corresponding articles usually received a considerable number of citations. CONCLUSIONS: Our analysis provides an empirical framework for setting up future TOSs based on the EORTC experience in oncology.
