| Samenvatting≠ | A multicenter phase II clinical trial is an interventional study conducted at two or more independent clinical sites to evaluate the preliminary efficacy and safety of a new treatment in a defined patient population, following demonstrated tolerability in phase I. By pooling patients across sites, the design achieves the sample sizes needed to estimate response rates and identify promising signals before committing to the larger investment of a phase III confirmatory trial. | A multicenter randomized clinical trial (RCT) is an experimental study in which eligible participants are randomly assigned to intervention or control arms simultaneously across two or more clinical sites. By combining the rigor of randomization with enrollment from geographically or institutionally diverse centers, this design produces large samples and externally valid effect estimates that single-center trials rarely achieve. It is the regulatory gold standard for confirmatory efficacy and safety evaluation of new treatments. |
