A Study of TAK-500 With or Without Pembrolizumab in Adults With Select Locally Advanced or Metastatic Solid Tumors

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.
