Study Endpoints

Primary Endpoints

Part 1 (Day-Time Dosing): Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability
Up to Week 8

An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.

Part 2 (Night-Time Dosing): Number of Participants with AEs as a Measure of Safety and Tolerability
Up to Week 9

An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.

Part 1: Single Ascending Dose (SAD): Number of Participants with Treatment Emergent Adverse Events (AEs) as a Measure of Safety and Tolerability
Up to Day 20

An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. Treatment-emergent were events between administration of study drug and up to Day 20 that were absent before treatment or that worsened relative to pre-treatment state.

Part 2: Multiple Ascending Dose (MAD): Number of Participants with Treatment Emergent Adverse Events as a Measure of Safety and Tolerability
Up to Day 28

An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. Treatment-emergent were events between administration of study drug and up to Day 28 that were absent before treatment or that worsened relative to pre-treatment state.

Number of Participants with Abnormalities in Vital Signs, Physical Examinations, Electrocardiogram (ECG), Cardiac Telemetry and Clinically Significant Laboratory Findings
Pre-dose, up to Day 20 (SAD) and up to Day 28 (MAD)

Number of participants with abnormalities in vital signs, physical examinations, ECG, cardiac telemetry and clinically significant laboratory findings will be measured.

ArmTypeDescription
Part 1 (Panel 1): JNJ-55375515 and placeboEXPERIMENTALParticipants will receive dose level (DL) 1 of JNJ-55375515 (starting dose) or placebo on Day 1 of period 1 based on their randomization sequence 1, 2 or 3. Dose of the study medication will be escalated to DL 3 (period 2) and a maximum of DL 5 (period 3) based on the safety and tolerability profile and pharmacodynamic (PD) profile assessed at the preceding dose level. A wash-out period of at least 10 days will be maintained between study drug administrations.
Part 1 (Panel 2): JNJ-55375515 and placeboEXPERIMENTALParticipants will receive DL 2 of JNJ-55375515 (starting dose) or placebo on Day 1 of period 1 based on their randomization sequence 1, 2 or 3. Dose of the study medication will be escalated to DL 4 (period 2) and a maximum of DL 6 (period 3) based on the safety and tolerability profile and PD profile assessed at the preceding dose level. A wash-out period of at least 10 days will be maintained between study drug administrations.
Part 2: JNJ-55375515 and placeboEXPERIMENTALParticipants will randomly be assigned to one of four treatment sequences 1, 2, 3 or 4. In the first 3 sequences, participants will receive 2 doses of JNJ-55375515 and placebo. Participants assigned to sequence 4 will receive placebo only in all periods. 3 dose levels will be tested in Part 2 based on Part 1 and will not exceed those evaluated in Part 1.

Fasted/fed condition will be determined based on tolerability and pharmacokinetics (PK) from Part 1.
