Phase 3 Study of Toripalimab and Tifcemalimab for Limited-stage Small Cell Lung Cancer

This study is testing two drugs, toripalimab and tifcemalimab, alone or in combination, as a treatment after initial chemoradiotherapy for limited-stage small cell lung cancer (LS-SCLC). LS-SCLC is a type of lung cancer that has not spread widely. Toripalimab targets a protein called PD-1, and tifcemalimab targets BTLA; both are monoclonal antibodies (a type of immune therapy). The goal is to see if these treatments can help patients live longer and prevent the cancer from growing. You might be able to join if you are 18 or older, have confirmed LS-SCLC, and your cancer has not worsened after your initial chemoradiotherapy. The study is currently unclear about its recruitment status.

Study design
This is a Phase 3, randomized, double-blind, placebo-controlled study involving 756 participants. Participants will be assigned to one of three groups to receive toripalimab alone, tifcemalimab in combination with toripalimab, or placebo.
What's involved
