An extended labeling claim has added detection of three additional EGFR mutations to help ID NSCLC patients for whom Boehringer Ingelheim's Gilotrif is indicated.
The researchers found that most advanced EGFR-mutant lung cancer patients harbored changes in an average of two to three other oncogenes.
The changes include recommendations for first line immunotherapy in patients with high PD-L1 expression, and clarification on use of targeted therapies.
The so-called universal CDx approved by the FDA can gauge alterations across multiple genes associated with response to three lung cancer treatments.
Clinicians say they are using blood-based tests for patients who can't be biopsied as a way to get test results sooner, but implementing tests smartly and appropriately remains a challenge.
In head-to-head studies, a next-generation EGFR inhibitor and an ALK inhibitor beat their older counterparts in staving of cancer progression.
Results from a recent study clarify some conflicting prior determinations, and provide a new rationale to further explore the FCGR2A biomarker in prospective trials.
Genentech's Alecensa and AstraZeneca's Tegrisso are the latest precision lung cancer drugs, and Xalkori might soon be an option for a new molecular subpopulation.
Non-small cell lung cancer patients with EGFR mutations now have three treatment choices, and AstraZeneca is working on newer personalized treatment options.
