Inclusion criteria
. Age ≥18 years.
. Histologically or cytologically confirmed locally advanced or metastatic NSCLC (Stage IIIB, IIIC, or IV).
. Documented failure after ≥1 prior line of EGFR TKI therapy with concurrent C797S mutation.
. At least one measurable target lesion per RECIST v1.1 criteria.
Exclusion criteria
. Presence of other well-documented driver gene mutations (e.g., ALK fusion, ROS1 fusion, KRAS activating mutations, MET exon 14 skipping, HER2 mutations, RET fusion).
. Histological or phenotypic transformation (e.g., NSCLC to SCLC transformation, epithelial-to-mesenchymal transition) confirmed by tumor tissue obtained within 6 months prior to first dose.
. ≥ Grade 2 toxicities (per CTCAE v6.0) attributed to prior anti-tumor therapy (excluding alopecia and stable neurotoxicity).
. History of other primary malignancies.
. Inadequate bone marrow reserve or hepatic/renal organ function.
. Clinically significant cardiac abnormalities or severe/uncontrolled/active cardiovascular disease.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Progression Free Survival (PFS)
Timeframe: From baseline, then every 6 weeks, until disease progression or discontinuation from study. From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months.
