Ed clinical trials in oncology. Measuring OS as an endpoint in clinical trials needs a sizable volume of individuals and lengthy duration of followup to demonstrate a statistically meaningful distinction among two or extra treatment options. These particular needs raise each the cost and duration of trials. In mCRC, PFS has been validated as a surrogate for OS in randomized clinical trial HEPACAM Protein site assessing first-line chemotherapy [302]. This outcome is available considerably earlier than OS, as a result shortening the duration of trials. Furthermore a smaller sample size is needed to acquire PFS and demonstrate a statistical distinction between two therapy arms. Even though PFS was a powerful surrogate for OS when assessing the efficacy of a single-line of remedy, the prediction might not be as accurate for individuals getting subsequent lines. Therefore, composite endpoints including duration of illness manage (DDC) and time to failure of technique (TFS) have been defined and evaluated to compensate for the disadvantages from the aforementioned endpoints [33, 34].STRATEGIC-1- Direct comparison of both strategiesOxaliplatin-based therapy, OPTIMOX or oxaliplatin stopand-go with fluoropyrimidines and FOLFOX-bevacizumab,STRATEGIC-1 is often a randomized trial made to determine the top sequence of therapy in sufferers affected by mCRC and to define subsets of the population which will benefit most from each method. The study follows 4 prosperous GERCOR (Groupe Coop ateurChibaudel et al. BMC Cancer (2015) 15:Page 3 ofMultidisciplinaire en Oncologie) trials evaluating the best use of offered drugs: the C97-1 trial that compared FOLFIRI followed by FOLFOX and the reverse sequence, the OPTIMOX1 [6], which evaluated the concept of maintenance therapy with fluoropyrimidine alone which is oxaliplatin stop-and-go strategy [18], the OPTIMOX2 that examined the total cease of chemotherapy [19], along with the DREAM trial (OPTIMOX3) which studied maintenance therapy with targeted agents (bevacizumab +/- erlotinib) [35].Ethics and regulatory considerationsMethods/DesignPrimary ObjectiveThe major objective will be to demonstrate a difference when it comes to DDC in between the two remedy strategies: FOLFIRI-cetuximab followed by an oxaliplatin-based chemotherapy (SAA1 Protein manufacturer modified FOLFOX6 [mFOLFOX6] or modified XELOX [mXELOX]) with bevacizumab vs. OPTIMOX-bevacizumab followed by an irinotecan-based chemotherapy (modified FOLFIRI3 or FOLFIRI1) with bevacizumab followed by an anti-EGFR agent (cetuximab or panitumumab) with/without irinotecan, in individuals with unresectable wild-type RAS mCRC.Secondary ObjectiveThis study is to be conducted in accordance with globally accepted standards in the Good Clinical Practice (International Conference of Harmonization [ICH]-E6), the European Directive 2001/20/EC, the most recent version from the Declaration of Helsinki, and in agreement using the Coordinated Program for gaining National Wellness Service Permission (NIHR CSP) distinct to France. The study protocol was approved for all participating centers by the French well being authorities (the Agence Nationale de S uritdu M icament et des Produits de Sant[ANSM] on June 24, 2013 as well as the Independent Ethics Committee “Ile de France Paris VI” La PitiSalp ri e on April 12, 2013) and was registered on 25 April, 2013 at EudraCT database (EudraCT 2013-001928-19) and on 23 July, 2013 at Clinicaltrials.gov (NCT01910610).
