For decades, the fight against cancer was based on oncolytic drugs aimed at eradicating malignant cells (killing strategy). The main flaws of this approach were its toxicity and the consequent emergence of resistance. New views on tumour biology consider tumours as complex organs involving dynamic interactions between their components. This implies the existence of dormant states and thus of a new therapeutic strategy aimed at inducing or extending tumour dormancy (containment strategy). The aim of this overview was to quantify the relative importance of these two strategies among the clinical trials (240 phase 1 and 186 phase 2 trials), launched or still in the pipeline and sponsored by the pharmaceutical industry in 2009. The most frequently targeted molecular entities are vascular endothelial growth factors (VEGFRs) (19 drugs), ErBBs (17 drugs), c‐met (14 drugs), tubulin (12 drugs), IGFRs (12 drugs). The main result of this overview is that the killing strategy is still largely prevailing since 326 drugs in 2009 (77% of the drugs tested in clinical trials in 2009) referred to this strategy, whereas 100 drugs could be attributed to the containment or mixed strategies in 2009. To obtain a dynamic view of the repartition of drugs between the killing strategy and the containment or mixed strategies, the present work should be renewed every 3–4 years.
