The main question it aims to answer is: • What the body does to the study drug, which is called "pharmacokinetic" Participants will receive investigational product (IP) administration every 3 weeks, maximum 18 cycles over about 51 weeks and blood sample will be collected. Researchers will compare 3 medicines (SB27, EU sourced Keytruda, and US sourced Keytruda) to see if SB27 works in the same way as EU and US sourced Keytruda.
