A Study of Orally Administered JNJ-56136379 to Evaluate Safety, Tolerability and Pharmacokinetics After Single Ascending Doses and One Multiple Dose Regimen in Healthy Participants (Part I), and After Multiple Dose Regimens in Participants With Chronic Hepatitis B (Part II)

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate pharmacokinetics and safety data including serious and other adverse events, physical examinations, vital signs, 12-lead electrocardiograms (ECGs) and clinical laboratory results (including biochemistry, hematology, and urine).

Detailed Description
-----------------
Part 1: This is a first-in-human (FIH), double-blind (neither the researchers nor the participants know what treatment the participant is receiving), randomized (study medication assigned to participants by chance), placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect) study. Part 1 includes healthy adult participants, divided into 3 panels (Panel 1, 2 and 3) and in Part 2 adult Chronic Hepatitis B Participants will be included, in Sessions VIII to XI and Optional Sessions A-B-C (Panel 4). The study will consists of screening phase (part 1: [less than or equal to <=28 days before the first intake of study drug; part 2: [<=56 to greater than or equal to {>=} 20 days before the first intake of study drug), Treatment Phase (multiple dose phase in part 1: Day -1 up to 12 or 19 days; part 2: up to 4 weeks) and Follow up Phase (part 1: 30-35 days after last study drug intake or after dropout; part 2: up to week 8 after actual end of study drug treatment). Participants' safety will be evaluated throughout the study.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Part 1: Single Dose Escalation<br>The single dose escalation phase of the study will consist of 6 dosing sessions (Sessions I to VI) evaluated in 2 panels (Panels 1 and 2). The dose of JNJ-56136379 will be consecutively escalated over 5 levels, alternating between the 2 panels. Panel 1 will receive 3 single doses (SD1, SD3 and SD3fed) in Sessions I, III and V, respectively. Panel 2 will receive 3 single doses (SD2, SD4 and SD5) in Sessions II, IV and VI, respectively. There will be a washout period of at least 14 days between consecutive JNJ-56136379/placebo dosing in each individual participant. | Drug: JNJ-56136379<br>* JNJ-56136379 oral tablets will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>Drug: Placebo<br>* Matching placebo to JNJ-56136379 will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>|
| Experimental: Part 1: Multiple dose session<br>After completion of the fifth single dose session another panel of healthy participant (panel 3) receive multiple doses of JNJ-56136379 at one dose level (MDx) or placebo for 12 or 19 consecutive days (Session VII) in fed or fasted conditions. | Drug: JNJ-56136379<br>* JNJ-56136379 oral tablets will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>Drug: Placebo<br>* Matching placebo to JNJ-56136379 will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>|
| Experimental: Part 2: Multiple dose escalation<br>Multiple dose levels will be given in Panel 4 in Session VIII (European sites), Sessions IX and X (European and/or Asian sites) Session XI (Asian sites) for 28 consecutive days in fed conditions. Optional Sessions A-B-C (Panel 4) used for further dose evaluations at European and/or Asian sites. Per session, participants will receive JNJ 56136379 or placebo. Dose progression to the next multiple dose level may be adapted based on the emerging safety and PK outcome of the previous dosing levels. | Drug: JNJ-56136379<br>* JNJ-56136379 oral tablets will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>Drug: Placebo<br>* Matching placebo to JNJ-56136379 will be given in Part 1 (single dose escalation and multiple dose session) and Part 2 (multiple dose escalation).<br>|
