Études cliniques de phases 0, 1 et 2 en cancérologie : questions d'actualité

We propose here a general review of current questions related to early trials, including the choice of the primary endpoint, role of bayesian designs, role of stratification and randomization for phase 2 trials, patient selection, and new designs for phase 1 and phase 0 trials. We also discuss the difficulties to apply such methodologies to molecular targeted therapies development.
