Resum	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.	Dose-response analysis quantifies the relationship between the magnitude of an exposure (the dose) and the probability or rate of an outcome (the response). It is a core analytical strategy in epidemiology and toxicology, providing evidence that increasing exposure systematically increases — or decreases — the risk of disease. A demonstrated dose-response gradient is one of Bradford Hill's classic criteria supporting causal inference.
