Activity of osimertinib in a patient with stage IV non-small cell lung cancer harboring HER2 exon 19, p.L755P mutation: case report
[Paper-level Aggregated] PMCID: PMC10183391
Evidence Type(s): Oncogenic, Predictive, Functional
Justification: Oncogenic: The text describes a patient with stage IV NSCLC harboring the HER2 exon 19 p.L755P mutation, which is associated with the disease and indicates a potential role in tumorigenesis. Predictive: The evidence suggests that the presence of the HER2 exon 19 p.L755P mutation may predict the efficacy of osimertinib treatment, as the patient achieved a partial response after treatment. Functional: The text indicates that osimertinib has demonstrated activity against the HER2 exon 19 p.L755P mutation in both pre-clinical studies and in the reported case, suggesting a functional impact of the mutation on treatment response.
