    Roche and Zentalis Present Pivotal Oncology Survival and Efficacy Data at ESMO 2026

    Question

    Roche and Zentalis Present Pivotal Oncology Survival and Efficacy Data at ESMO 2026

    Direct answer

    Clinical presentations at the European Society for Medical Oncology (ESMO) 2026 Congress showed significant advancements in targeted solid tumor therapies. Roche demonstrated that divarasib outperformed established first-generation KRAS G12C inhibitors in pivotal lung cancer trials, positioning the compound for regulatory filing. In platinum-resistant ovarian cancer, Zentalis Pharmaceuticals presented interim survival data showing azenosertib more than doubled median overall survival to 15.8 months in Cyclin E1-positive patients compared to the negative arm (7.5 months). The biomarker-driven outcome materially de-risks the drug's Phase III clinical trajectory.
