What this study is about
In the sponsor’s own words, from the registry.
This is an early phase trial designed to evaluate the safety, tolerability, and preliminary antitumor activity of RPTR-1-201 in adults with advanced solid tumors. The trial includes dose escalation and dose expansion parts and will evaluate RPTR-1-201 as monotherapy and in combination with an anti-PD-1 monoclonal antibody.
