Core Insights - Roche announced positive results from the Phase III IMforte study of Tecentriq in combination with lurbinectedin for extensive-stage small cell lung cancer, showing a 46% reduction in the risk of disease progression or death and a 27% reduction in the risk of death compared to Tecentriq alone [1][6]. Study Results - The IMforte study demonstrated that the combination therapy significantly extended median overall survival (OS) to 13.2 months compared to 10.6 months for Tecentriq alone, with a stratified hazard ratio (HR) of 0.73 [2][3]. - Median progression-free survival (PFS) was also improved, with 5.4 months for the combination therapy versus 2.1 months for Tecentriq alone, yielding a stratified HR of 0.54 [2][3]. Study Design - The IMforte study was a Phase III, open-label, randomized trial involving 660 patients in the induction phase and 483 patients randomized for maintenance therapy [3][4]. - Patients received four cycles of induction therapy with Tecentriq, carboplatin, and etoposide before being randomized to maintenance therapy [3]. Safety Profile - The safety profile of the combination therapy was consistent with the known safety profiles of both Tecentriq and lurbinectedin, with no new safety signals observed [1][2]. Implications for Treatment - The results from the IMforte study are considered potentially practice-changing, offering a new option for patients with extensive-stage small cell lung cancer, a group with high unmet medical needs [2][6].
