A Study to Evaluate the Effect of Hepatic Impairment on the Pharmacokinetics of Erdafitinib

Study Overview
=================
Brief Summary
-----------------
The primary purpose of the study is to characterize the single dose pharmacokinetic of erdafitinib in participants with impaired hepatic function relative to participants with normal hepatic function.

Hepatic Impairment

Intervention / Treatment
-----------------
* Drug: Erdafitinib


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Man or woman must have a clinically stable hepatic function as confirmed by the serum bilirubin and transaminase levels measured during screening and those measured on Day -1 If a woman (a) must not be of childbearing potential postmenopausal or surgically sterile (b) must agree to not donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for 3 months after the study drug administration If a woman who is considered surgically sterile but not postmenopausal, must have a negative serum beta-human chorionic gonadotropin (beta-hCG) pregnancy test at screening (exemptions: pregnancy test not required in female participants with prior hysterectomy or prior bilateral oophorectomy) If a woman, must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for 3 months after the study drug administration Participants with hepatic impairment must meet the Child-pug classification for mild, moderate or severe hepatic impairment and must have stable hepatic function Exclusion Criteria: History or current evidence of ophthalmic disorder, such as central serous retinopathy (CSR) or retinal vein occlusion, active wet age related macular degeneration, diabetic retinopathy with macular edema, uncontrolled glaucoma, corneal pathology such as keratitis, keratoconjunctivitis, keratopathy, corneal abrasion, inflammation or ulceration Any surgical or medical condition that may alter the absorption, metabolism, or excretion of the study drug (example, gastrectomy, Crohn's disease etc), with the exception of hepatic impairment History of drug abuse according to Diagnostic and Statistical Manual of Mental Disorders (5th edition) (DSM-V) criteria within 6 months before screening or positive test result(s) for drugs of abuse (including barbiturates, opiates, cocaine, cannabinoids, amphetamines, hallucinogens, and benzodiazepines) at screening and on Day -1 Known allergy to the study drug or any of the excipients of the formulation (Physical Description of Study Drug[s], for a list of excipients) Donated blood or blood products or had substantial loss of blood (more than 500 milliliter [mL]) within 3 months before study drug administration or intention to donate blood or blood products during the study

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cohort 1: Normal Hepatic Function<br>Participants with normal hepatic function will receive 6 milligram (mg) erdafitinib as a single oral dose under fasted conditions on Day 1. | Drug: Erdafitinib<br>* Participants will receive 6 mg (2*3 mg tablet) erdafitinib as a single oral dose on Day 1. Participants in Cohort 4 may receive a lower dose if warranted by preliminary safety and PK data from Cohorts 2 and 3.<br>* Other names: JNJ-42756493;|
| Experimental: Cohort 2: Mild Hepatic Impairment<br>Participants with mild hepatic impairment (Child-Pugh score of 5 or 6) will receive 6 mg erdafitinib as a single oral dose under fasted conditions on Day 1. | Drug: Erdafitinib<br>* Participants will receive 6 mg (2*3 mg tablet) erdafitinib as a single oral dose on Day 1. Participants in Cohort 4 may receive a lower dose if warranted by preliminary safety and PK data from Cohorts 2 and 3.<br>* Other names: JNJ-42756493;|
| Experimental: Cohort 3: Moderate Hepatic Impairment<br>Participants with moderate hepatic impairment (Child-Pugh score of 7 to 9) will receive 6 mg erdafitinib as a single oral dose under fasted conditions on Day 1. | Drug: Erdafitinib<br>* Participants will receive 6 mg (2*3 mg tablet) erdafitinib as a single oral dose on Day 1. Participants in Cohort 4 may receive a lower dose if warranted by preliminary safety and PK data from Cohorts 2 and 3.<br>* Other names: JNJ-42756493;|
| Experimental: Cohort 4: Severe Hepatic Impairment<br>Participants with severe hepatic impairment (Child-Pugh score of 10 to 15) will only be enrolled to receive appropriate dose level of erdafitinib after review of preliminary safety and pharmacokinetic (PK) data from the mild and moderate hepatic impairment cohorts. | Drug: Erdafitinib<br>* Participants will receive 6 mg (2*3 mg tablet) erdafitinib as a single oral dose on Day 1. Participants in Cohort 4 may receive a lower dose if warranted by preliminary safety and PK data from Cohorts 2 and 3.<br>* Other names: JNJ-42756493;|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Observed Plasma Concentration (Cmax) | Cmax is the maximum observed plasma concentration. | Up to 21 days | 
| Time to Reach the Maximum Observed Plasma Concentration (Tmax) | Tmax is the time to reach maximum observed plasma concentration. | Up to 21 days | 
| Area Under Plasma Concentration-Time Curve (AUC) | AUC is area under plasma concentration-time curve. | Up to 21 days |
