What This Trial Is Studying

In this study researchers are testing Risvutatug rezetecan also known as (Ris-Rez) a new medicine that targets specific proteins (B7-H3) on cancer cells, thereby reducing the cancer's ability to grow and spread. This study specifically aims to evaluate how well Ris-Rez works in treating relapsed SCLC compared to standard treatment topotecan, by checking whether Ris-Rez makes cancers smaller or disappear completely and if it helps participants live longer. The study is also assessing whether Ris-Rez is safe and tolerated well by participants compared to topotecan and provide a better understanding…
