Study 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.

To evaluate the safety, tolerability, antitumor activity, pharmacokinetics (PK), and pharmacodynamics of TAK-500 when used as a single agent (SA) and in combination with pembrolizumab in participants with locally advanced or metastatic solid tumors. To assess the effects of TAK-500, when given alone and when given with pembrolizumab, on adults with locally advanced or metastatic solid tumors. Dose escalation in both cohorts will be guided by Bayesian Optimal Interval design. To determine safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of TAK-500 as a single agent and in combination with pembrolizumab in CCR2-enriched solid tumors A Simon’s 2-stage design with futility analyses based on response per RECIST v1.1 will be used for 2nd-line NS NSCLC and 2nd-line PDAC. A single-stage statistical design will be utilized for 3rd-line NS NSCLC and RCC
