A Trial to Find Out if Vidutolimod Together With Cemiplimab is Safe and if it Works in Adult Participants With Advanced Cancer or Metastatic Cancer

Study Overview
=================
Brief Summary
-----------------
The goal of this study is to learn if giving cemiplimab and vidutolimod together could be effective in treating advanced cancer. The main questions it aims to answer are: How many participants' cancers respond to vidutolimod together with cemiplimab? Is vidutolimod together with cemiplimab safe and well-tolerated? How well does vidutolimod together with cemiplimab treat participants' cancer? Participants will receive trial treatment for up to 2 years. 30 days after stopping treatment, participants will have an end of treatment visit. After that visit, the trial staff will continue to follow up with participants about every 3 months, until the trial ends.

| Efficacy of vidutolimod in combination with cemiplimab in the study participants | Efficacy is measured by: Duration of response (DOR), defined as the time from date of first documented response (CR or PR) to date of documented progressive disease (PD), based on RECIST v1.1 Response in injected and noninjected target lesions per RECIST v1.1. Progression-free survival (PFS), defined as the time from date of first dose of study treatment to date of documented PD based on RECIST v1.1 or death, whichever occurs first. Overall survival (OS), defined as the time from date of first dose of study treatment to date of death | Up to 42 Months |
