A Science-Based Methodology Framework for the Assessment of Combination Safety Risks in Clinical Trials.

Multiple components factor into the assessment of combination safety risks when two or more novel individual products are used in combination in clinical trials. These include, but are not limited to, biology, biochemistry, pharmacology, class effects, and preclinical and clinical findings (such as adverse drug reactions, drug target and mechanism of action, target expression, signaling, and drug-drug interactions). This paper presents a science-based methodology framework for the assessment of combination safety risks when two or more investigational products are used in clinical trials.

Biomarker-Directed Phase II Platform Study in Patients With EGFR Sensitizing Mutation-Positive Advanced/Metastatic Non-Small Cell Lung Cancer Whose Disease Has Progressed on First-Line Osimertinib Therapy (ORCHARD).

Introduction: Osimertinib, a third-generation, irreversible, epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), selectively inhibits both EGFR-TKI sensitizing (EGFRm) and EGFR T790M resistance mutations and has demonstrated efficacy in non-small cell lung cancer (NSCLC) CNS metastases. Most patients with EGFRm NSCLC treated with osimertinib will eventually develop resistance. ORCHARD (NCT03944772) is a phase II study aiming to characterize first-line osimertinib resistance and identify post-progression treatments.
