Summary

This early-stage study is testing a modified virus called RP3, both alone and combined with an existing immunotherapy drug, in people with advanced solid tumors that haven't responded to standard treatments. The main goals are to find the safest dose and understand the side effects. The study involves 123 adults and is the first step to see if this approach is safe enough for larger trials.
