Plain-language summary
This is a prospective, single-arm, multi-center, phase II clinical trial to evaluate the efficacy and safety of Chidamide in combination with Ivonescimab in the treatment of advanced non-small cell lung cancer with secondary immune resistance and high YAP protein expression.

Inclusion criteria
. Written informed consent must be signed before implementing any trial-related procedures;
. Age ≥18 years old;
. Have histologically or cytologically confirmed locally advanced (IIIB/IIIC stage), metastatic or recurrent (IV stage) non-small cell lung cancer (NSCLC) that is not operable and not suitable for radical concurrent chemoradiotherapy, as classified by the 9th edition of the TNM staging system of the International Association for the Study of Lung Cancer and the American Joint Committee on Cancer;
. Previously received first-line PD-1/PD-L1 inhibitor monotherapy or combination therapy, with a progression-free survival (PFS) of ≥ 6 months under the initial PD-1/PD-L1-containing treatment regimen;
. Previously received only first-line systemic treatment;
. Able to provide 15 pieces of biopsied tumor tissue or tumor tissue sections after PD-1/PD-L1 treatment resistance, pathologically confirmed as non-small cell lung cancer, and centrally laboratory-confirmed high YAP protein expression. Eligible subjects voluntarily provide 5-15 sections of tumor tissue samples from initial diagnosis. (YAP immunohistochemical staining intensity is graded as 0 (negative), 1+ (weak), 2+ (moderate), and 3+ (strong); the proportion of positive tumor cells is graded as 0 (0-5%), 1+ (6-25%), 2+ (26-50%), 3+ (51-75%), and 4+ (\>75%). The YAP IHC score is calculated by multiplying the staining intensity by the proportion of positive tumor cells: YAP IRS = Staining Intensity (A) × Proportion of Positive Tumor Cells (B). A YAP IHC score \< 6 indicates low YAP expression, and ≥ 6 indicates high YAP expression);
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) per Response Evaluation Criteria in Solid tumors (RECIST) v1.1
Timeframe: From the start of treatment until disease progression or death (assessed up to 24 months)
. Asymptomatic brain metastasis patients are eligible for enrollment;
. Palliative radiotherapy completed within 2 weeks before study enrollment is allowed, and radiotherapy-related toxicity has recovered to ≤ Grade 1 (CTCAE 5.0). Radiated lesions are not considered evaluable lesions unless there is evidence of progression after radiotherapy;
Exclusion criteria
. Have a history of severe bleeding tendency or coagulation disorders; have significant clinical bleeding symptoms within 4 weeks before enrollment, including but not limited to gastrointestinal bleeding, hemoptysis (defined as coughing or expectorating ≥ 1 teaspoon of fresh blood or small blood clots or only coughing blood without sputum, subjects with blood in sputum are allowed to enroll), nasal bleeding (excluding epistaxis and retracted nasal blood); continuous antiplatelet or anticoagulant therapy within 14 days before the first dose;
. History of gastrointestinal perforation and/or fistula, gastrointestinal obstruction (including incomplete intestinal obstruction requiring parenteral nutrition), esophagogastric varices, severe ulcers, unhealed wounds, abdominal fistulas, intra-abdominal abscesses, or acute gastrointestinal bleeding within 6 months before the first dose; extensive intestinal resection (partial colectomy or extensive small bowel resection complicated by chronic diarrhea);
. Hypersensitivity to any study drug or its components;
. Exclusion of central squamous cell lung cancer invading large blood vessels;
. Patients who experienced Grade 3 or above immune-related adverse reactions with prior immunotherapy drugs, and investigators assess that immunotherapy has safety concerns with risks outweighing benefits;
. Any arterial thromboembolic event, Grade 3 or above venous thromboembolic event as specified by NCI CTCAE 5.0, transient ischemic attack, cerebrovascular accident, hypertensive crisis, or hypertensive encephalopathy within 6 months before the first dose;
. Acute exacerbation of chronic obstructive pulmonary disease within 4 weeks before the first dose;
. Complicated with severe uncontrolled concurrent infections or other severe uncontrolled comorbidities, moderate or severe renal impairment (e.g., progressive infection, uncontrolled hypertension, diabetes mellitus, etc.);
