| Kokkuvõte≠ | A multicenter Phase I clinical trial is the first systematic administration of an investigational agent to humans, conducted simultaneously across two or more clinical sites. Its primary objectives are to characterize the safety and tolerability profile of the intervention, determine the maximum tolerated dose (MTD), and describe pharmacokinetic and pharmacodynamic behavior. Distributing enrollment across sites increases participant accrual speed and enhances the generalizability of early-phase safety data. | A Phase II clinical trial is the second stage in the drug or intervention development pipeline, conducted after Phase I safety testing. Its primary goal is to assess whether the intervention shows preliminary efficacy signals in a relevant patient population at the dose established in Phase I, while continuing to characterise the safety and tolerability profile. Phase II trials are generally smaller than Phase III confirmatory trials and serve as critical go/no-go decision points before large-scale investment. |
