Brief Summary
This study is about TAK-500, given either alone or with pembrolizumab, in adults with select locally advanced or metastatic solid tumors. The aims of the study are:
- to assess the safety profile of TAK-500 when given alone and when given with pembrolizumab.
- to assess the anti-tumor effects of TAK-500, when given alone and when given with pembrolizumab, in adults with locally advanced or metastatic solid tumors. Participants may receive TAK-500 for up to 1 year. Participants may continue with their treatment if they have continuing benefit and if this is approved by their study doctor. Participants who are receiving TAK-500 either alone or with pembrolizumab will continue with their treatment until their disease progresses or until they or their study doctor decide they should stop this treatment.

Outcome Measures
Primary Outcomes (6)
Dose Escalation: Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs)
Adverse event (AE) means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. A TEAE was reported as an AE for which the date of onset was on or after the first dose of any study drug and on or before the 30 days after the last dose of any study drug (or 90 days after the last dose of study drug for immune-mediated AEs).
Up to approximately 32.8 months
Dose Escalation: Number of Participants With Grade 3 or Higher TEAEs
AE means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. A TEAE was reported as an AE for which the date of onset was on or after the first dose of any study drug and on or before the 30 days after the last dose of any study drug (or 90 days after the last dose of study drug for immune-mediated AEs). TEAE Grades was evaluated as per the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 5.0.
Up to approximately 32.8 months
Dose Escalation: Number of Participants With Dose Limiting Toxicities (DLTs)
DLT was defined as any of the TEAEs that occur during Cycle 1 and are considered by the investigator to be at least possibly related to TAK-500 as a SA or in combination with pembrolizumab. Toxicity will be evaluated according to NCI CTCAE version 5.0.
Up to Cycle 1 (1 cycle = 21 days)
Dose Escalation: Number of Participants Reporting One or More Treatment-emergent Serious Adverse Events (SAEs)
A TEAE is an AE for which the date of onset was on or after the first dose of any study drug and on or before 30 days after the last dose of any study drug (or 90 days after the last dose of study drug for immune-mediated AEs). Treatment-emergent SAE is any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or is a medically important event.
Up to approximately 32.8 months
Dose Escalation: Number of Participants With One or More TEAEs Leading to Dose Modifications and Treatment Discontinuations
AE means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. A TEAE was reported as an AE for which the date of onset was on or after the first dose of any study drug and on or before the 30 days after the last dose of any study drug (or 90 days after the last dose of study drug for immune-mediated AEs).
Up to approximately 32.8 months
Dose Expansion: Overall Response Rate (ORR)
ORR is defined as the percentage of participants who achieve confirmed partial response (cPR) or confirmed complete response (cCR) (determined by the investigator) during the study in the response-evaluable population. ORR will be assessed as per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1. Complete response (CR): defined as disappearance of all target and non- target lesions and any pathological lymph nodes (whether target or non-target) must have reduction in short axis to less than \<10 mm. Partial response (PR): defined as at least a 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum diameters. cPR or cCR is defined as a PR or CR that is confirmed with additional imaging 6 weeks after initial response.
Up to approximately 32.8 months
