Core Viewpoint - Roche's Tecentriq and Tecentriq Hybreza have received FDA approval for maintenance treatment in extensive-stage small cell lung cancer (ES-SCLC), marking a significant advancement in treatment options for this aggressive disease [1][2]. Group 1: FDA Approval and Treatment Significance - The FDA approved Tecentriq and Tecentriq Hybreza in combination with lurbinectedin for adult patients with ES-SCLC whose disease has not progressed after first-line induction therapy [1]. - This approval represents the first and only combination therapy for first-line maintenance treatment of ES-SCLC, addressing a critical need in a disease with limited treatment options [1][6]. - The National Comprehensive Cancer Network (NCCN) has updated its guidelines to include this regimen as a category 2A preferred option for maintenance treatment [1]. Group 2: Clinical Study Results - The approval is based on the phase III IMforte study, which demonstrated that the combination therapy reduced the risk of disease progression or death by 46% and the risk of death by 27% compared to Tecentriq alone [2][4]. - The median overall survival for the combination therapy was 13.2 months, compared to 10.6 months for Tecentriq alone, with a stratified hazard ratio of 0.73 [2][4]. - Median progression-free survival was 5.4 months for the combination versus 2.1 months for Tecentriq alone, with a stratified hazard ratio of 0.54 [2][4]. Group 3: Background and Previous Approvals - Tecentriq was previously approved in 2019 in combination with chemotherapy for first-line treatment of adults with ES-SCLC, based on the IMpower133 study [3]. - The IMforte study enrolled 660 patients in the induction phase and randomized 483 patients in the maintenance phase, focusing on the efficacy and safety of the combination therapy [4][5].
