Abstract

Introduction: Breast cancer (BC), the most frequent cancer in women, is one “big killer” in oncology. Innovative, highly-priced drugs dramatically changed prognosis in affluent countries, where as most patients in low-income settings still lack access to innovative drugs. The geography of BC clinical trials with innovative drugs has not been investigated yet. Aim: We aimed at describing the geographic distribution of industry-sponsored BC clinical trials evaluating innovative“targeted small molecules” and monoclonal antibodies. Methods: Industry-sponsored trials registered as of June 30,2017 were extracted from clinicaltrials.gov. Search criteria were:(i) study type: Interventional studies; (ii) condition/disease: breastcancer; (iii) phases: all phases (1 to 4); (iv) funder type: industry.Countries were classified by income according to the World Bank. Results: 1323 trials were analysed.Among all phase 3,interventional, industry-sponsored clinical trials against BC, 141/276 (51.08%) involved middle income countries (MICs),including both lower-MICs 55/276 (20.99%) and upper-MICs 144/276 (52.17%). Phase 1 and 2 trials were run in MICs in smaller proportions (41/315, 13.02% and 146/676, 21.60%,respectively). Phase 4 trials involved MICs in 13/56 (23.21%) instances. No trials were run in low-income countries. Countries most frequently involved in trials were India (n=61), Ukraine(n=50), Philippines (n=21), Guatemala (n=17), Egypt(n=15) among lower-MICs, and Russian Federation (n=117),Brazil (n=108), Argentina and China (n=90 each), Mexico(n=78) among upper MICs.
