Brief Summary
-----------------
The primary purpose of this study is to evaluate the effect of food on the relative bioavailability of a single 9 milligram (mg) oral dose of erdafitinib in healthy participants.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Treatment Sequence 1: Erdafitinib 9 mg<br>Participants will receive 9 milligram (mg) dose of erdafitinib under fasted condition [Treatment A] in Period 1, and under fed (with high-fat and high-calorie breakfast) condition [Treatment B] in Period 2. Each Treatment Period will be separated by a washout of at least 28 days. | Drug: Erdafitinib<br>* Erdafitinib 9 mg (provided as one 4-mg tablet [G-024] and one 5-mg tablet [G-025]) will be administered orally on Day 1 in each Treatment Period of assigned sequence.<br>|
| Experimental: Treatment Sequence 2: Erdafitinib 9 mg<br>Participants will receive 9 mg dose of erdafitinib under fed (high-fat and high-calorie breakfast) condition [Treatment B] in Period 1, and under fasted condition [Treatment A] in Period 2. Each Treatment Period will be separated by a washout of at least 28 days. | Drug: Erdafitinib<br>* Erdafitinib 9 mg (provided as one 4-mg tablet [G-024] and one 5-mg tablet [G-025]) will be administered orally on Day 1 in each Treatment Period of assigned sequence.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Plasma Concentration (Cmax) | The Cmax is the maximum observed plasma concentration. | Predose, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, 144, 192, 240, 288, and 366 hours post dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Last Quantifiable Time (AUC [0-last]) | The AUC (0-last) is the area under the plasma concentration-time curve from time zero to last quantifiable time. | Predose, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, 144, 192, 240, 288, and 366 hours post dose | 
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC[0-infinity]) | The AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time, calculated as the sum of AUC (last) and C(last)/lambda(z); wherein AUC(last) is area under the plasma concentration-time curve from time zero to last quantifiable time, C(last) is the last observed quantifiable concentration, and lambda(z) is elimination rate constant. | Predose, 1, 2, 3, 4, 6, 8, 12, 24, 48, 72, 96, 144, 192, 240, 288, and 366 hours post dose | 

Secondary Outcome Measures
