A phase II trial found that for patients with HER2+ metastatic colorectal cancer, dual HER2-inhibitor therapy can be a similarly efficacious but less toxic alternative to EGFR inhibitor therapy. Exploratory analysis suggests greater HER2 amplification in a tumor may be associated with greater clinical benefit of dual HER2 inhibitor vs EGFR inhibitor therapy.
The REZILIENT3 trial, a global phase III clinical trial evaluating the combination of zipalertinib and platinum-based chemotherapy compared with chemotherapy alone in the first-line treatment of adult patients with previously untreated, locally advanced or metastatic non-small cell lung cancer harboring epidermal growth factor receptor exon 20 insertion mutations, met its primary endpoint of progression-free survival at a planned interim analysis.
