Promising Results for ifinatamab deruxtecan in Small Cell Lung Cancer Trial

Daiichi Sankyo and AstraZeneca's datopotamab deruxtecan has shown significant efficacy in treating patients with advanced or metastatic non-small cell lung cancer (NSCLC) who are TROP2-QCS biomarker positive. In a phase 3 trial, patients receiving this treatment experienced a median progression-free survival (PFS) of 6.9 months compared to 4.1 months for those on docetaxel, indicating a 43% reduction in the risk of disease progression or death. This analysis was presented at the IASLC 2024 World Conference on Lung Cancer. The TROPION-Lung01 trial evaluated the safety and efficacy of datopotamab deruxtecan against docetaxel in a diverse patient population. The results highlighted the importance of the TROP2 biomarker, which was measured using AstraZeneca's proprietary computational pathology platform. This innovative approach allowed for a more precise identification of patients likely to benefit from the treatment, addressing a critical gap in predictive biomarkers for TROP2 directed antibody drug conjugates. In the overall trial population, datopotamab deruxtecan reduced the risk of disease progression or death by 25%, showcasing its potential as a viable treatment option for NSCLC. The trial also reported adverse events, with grade 3 or higher treatment-related adverse events occurring in 30% of patients treated with datopotamab deruxtecan, compared to 46% in the docetaxel group. The collaboration between Daiichi Sankyo and AstraZeneca aims to advance the development of innovative therapies for lung cancer, a disease that continues to pose significant challenges. The promising results from this trial may pave the way for new treatment paradigms in NSCLC, particularly for patients with TROP2-QCS biomarker positive tumors.
