Brief summary

The purpose of this study is to evaluate the safety and tolerability of JNJ-95597528 after single and optional multiple ascending dose administration in healthy participants. For Optional Asthma Cohort: The purpose of this part is to evaluate the safety and tolerability of JNJ-95597528 in participants with mild to moderate asthma.

Interventions

Arms: Arm 1 - Single Ascending Dose (SAD) Cohort; Type: Experimental; Description: Healthy participants will receive a single dose of JNJ-95597528 or placebo through subcutaneous (SC) administration on Day 1. The first 3 SAD cohorts (SAD1, SAD2, SAD3) are required cohorts and the last 4 SAD cohorts (SAD4, SAD5, SAD6, SAD7) are optional cohorts. Arm 2 - Optional Multiple Ascending Dose (MAD) Cohort; Type: Experimental; Description: Healthy participants will be enrolled into 1 to 2 cohorts in th

The first 3 SAD cohorts (SAD1, SAD2, SAD3) are required cohorts and the last 4 SAD cohorts (SAD4, SAD5, SAD6, SAD7) are optional cohorts. Arm 2 - Optional Multiple Ascending Dose (MAD) Cohort; Type: Experimental; Description: Healthy participants will be enrolled into 1 to 2 cohorts in the MAD part and will receive 1 SC injection once a week for total of 3 SC injections of JNJ-95597528 or placebo starting on Day 1. Intervention name: JNJ-95597528 - Drug Associated arms: Single Ascending Dose (SAD) Cohort; and Optional Multiple Ascending Dose (MAD) Cohort JNJ-95597528 will be administered at a dose decided by data safety monitoring board (DSMB) equivalent starting from 100 mg up to a maximum cumulative dose of 1800 mg for SAD and MAD Cohorts. The dose will be escalated only if the safety and tolerability profiles are deemed acceptable as determined by safety data generated from SAD cohorts. It will be administered by medical professionals including registered nurses through subcutaneous injection. No monitoring adherence will be performed.

Arm 2 - Optional Asthma Cohort; Type: Experimental; Description: Participants in Part 2 with well-controlled mild to moderate stable asthma will receive a single dose of JNJ-95597528 or placebo through SC administration on Day 1. Arm 3: Optional Multiple Ascending Dose (MAD) Cohort Type: Experimental Description: Healthy participants will be enrolled into 1 to 2 cohorts in the MAD part and will receive 1 SC injection once a week for total of 3 SC injections of JNJ-95597528 or placebo starting on Day 1.
