Brief summary

The purpose of this study is to assess the mass balance (that is, cumulative excretion of total radioactivity \[TRA\] in urine and feces) and to characterize the pharmacokinetics (PK) of pevonedistat in whole blood, plasma, and urine, and of TRA in plasma and whole blood following a single 1-hour infusion of 25 milligram per square meter (mg/m\^2) \[14C\]-pevonedistat intravenous (IV) solution containing approximately 60 to 85 microcurie (mCi) (approximately 2.22-3.145 megabecquerel \[MBq\]) of TRA in participants with advanced solid tumors in Part A.

Detailed description

The drug being tested in this study is called Pevonedistat. Pevonedistat is being tested to treat people with advanced solid tumors. The study will enroll approximately 4 to 6 pharmacokinetics (PK)-evaluable participants in part A. After completion of the mass balance and absorption, distribution, metabolism, excretion (ADME) assessment in Part A of the study, eligible participants will have the opportunity to continue into Part B at a secondary study site, which would begin in approximately 2 weeks of completion of Part A. * \[14C\]-Pevonedistat 25 mg/m\^2 * Part B (optional): Pevonedistat in combination with chemotherapy regimens (Pevonedistat 25 mg/m\^2 + docetaxel 75 mg/m\^2 or pevonedistat 20 mg/m\^2 + carboplatin 20 mg/m\^2 + paclitaxel 175 mg/m\^2) All participants will receive study drug via intravenous route. This multi-center trial will be conducted in Hungary. Participants will remain confined to the study site for 9 to 14 days in Part A. Participation in Part B is optional, participants will be re-evaluated for inclusion/exclusion criteria before administrating treatment. Participants will undergo treatment in Part B for a maximum of 12 cycles (21 days cycle each) and will include approximately 36 weeks for Part A and B combined. Participants will attend an end of study visit 30 days after the last dose of study drug in both Part A and B.

Part B: Number of Participants With Best Overall Response as Per Investigator's AssessmentUp to Cycle 11 (Cycle length =21 days)The best overall response was defined as the participants with best response among complete response (CR) or partial response (PR) or stable disease (SD), or progressive disease (PD). It was assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CR: disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to less than (\<) 10 millimeter (mm). PR: at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters as the best overall response after randomization. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).

Part B: Number of Participants With Best Overall Response as Per Investigator's Assessment

The best overall response was defined as the participants with best response among complete response (CR) or partial response (PR) or stable disease (SD), or progressive disease (PD). It was assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. CR: disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to less than (\<) 10 millimeter (mm). PR: at least a 30 percent (%) decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters as the best overall response after randomization. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. PD: at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study).

Time frame: Up to Cycle 11 (Cycle length =21 days)

Population: The response-evaluable population included all participants who received at least 1 dose of study drug in Part B, had measurable disease as entry criteria for Part B, and had at least 1 post-baseline disease assessment.
