Study Endpoints
Primary Endpoints
Part 1: Number of Participants with Adverse Events (AE) by Severity
Up to approximately 2 years 10 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Severity of AEs will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version (v) 5.0. by using standard grades as follows: Grade 1: Mild; asymptomatic or mild symptoms; Grade 2: Moderate; minimal, local or noninvasive intervention indicated; Grade 3: Severe but not immediately life threatening; hospitalization or prolongation of hospitalization indicated; Grade 4: Life-threatening consequences; and Grade 5: Death related to AE.

Part 1: Number of Participants with Dose-Limiting Toxicities (DLTs)
Up to 28 days

High grade hematologic or non-hematologic toxicities with exceptions and/or toxicities leading to treatment discontinuation will be regarded as DLT.

Part 1: Number of Participants with AEs by Severity Related to Delivery Device and/or Procedure
Up to approximately 2 years 10 months

An AE is any untoward medical occurrence in a participant administered a pharmaceutical (investigational or non investigational) product. An AE does not necessarily have a causal relationship with the treatment. Participants with AEs related to delivery device and/or procedure will be reported.

Part 1: Number of Participants who Received Planned Total Dose per Level
Up to approximately 28 days

Number of participants who received planned total dose per level will be reported.

Part 2: Administered Tumor Response Rate
Up to approximately 2 years 10 months

Administered tumor response rate is defined as the percentage of JNJ-1761981 administered lesions that achieve complete response (CR) or partial response (PR).

Secondary Endpoints
Parts 1 and 2: Plasma Concentration of Free and Total Platinum
Up to approximately 2 years 10 months
Part 1: Administered Tumor Response Rate
Up to approximately 2 years 10 months
Parts 1 and 2: Administered Tumor Duration of Response
Up to approximately 2 years 10 months
