What was measured

Tmax is the time to reach maximum observed plasma concentration of metformin alone or in combination with erdafitinib

Analysis population: Pharmacokinetic analysis set included all participants who received at least 1 dose of study drug and had at least 1 sample collected during treatment to determine the drug concentration. Here 'N' (number of participants analyzed) signifies number of participants who were evaluable for this outcome measure.

Groups in this outcome
