Combining Befotertinib and Icotinib for treating specific lung cancer mutations
A Phase II Study to Assess Befotertinib and Icotinib as First-Line Treatment in Patients With Locally Advanced or Metastatic NSCLC and Uncommon EGFR Mutation(IcomBine, GASTO-10114)
This study is testing if combining two targeted lung cancer treatments, Befotertinib and Icotinib, can help patients with specific EGFR mutations in Non-Small Cell Lung Cancer feel better and improve their outcomes.

What this trial studies
This clinical trial investigates the effectiveness of two targeted therapies, Befotertinib and Icotinib, as a first-line treatment for patients with Non-Small Cell Lung Cancer (NSCLC) harboring uncommon EGFR mutations. The study focuses on patients with specific mutations such as G719X, L861Q, and S768I, who have not received prior systemic therapy for their advanced disease. Participants will be monitored for treatment response and safety, with the aim of improving outcomes for this specific patient population.
Who should consider this trial
Good fit: Ideal candidates include adults aged 18 and older with pathologically confirmed adenocarcinoma of the lung and specific uncommon EGFR mutations.
Not a fit: Patients with common EGFR mutations or those who have received prior systemic therapy for their advanced NSCLC may not benefit from this study.
Why it matters
Potential benefit: If successful, this treatment approach could provide a new effective option for patients with rare EGFR mutations in NSCLC.
How similar studies have performed: While studies targeting common EGFR mutations have shown success, this approach for uncommon mutations is relatively novel and less tested.
Eligibility criteria

Inclusion Criteria:
1. 18 years of age or older.
2. Pathologically confirmed adenocarcinoma of the lung, with locally advanced or metastatic disease and not amenable to curative surgery or radiotherapy (stage IIIB, IIIC or IV disease based on the eighth edition of the American Joint Committee on Cancer (AJCC) TNM classification).

5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
6. Predicted survival ≥ 3 months.
7. At least 1 measurable tumor lesion without radiotherapy as per RECIST v1.1.
8. Agree to use effective contraception during the study period and for at least 3 months after completion of the study treatment.
9. Provision of informed consent prior to any study procedure.
Exclusion Criteria:
1. Combined with other malignancy(except for clinically cured in situ cervix carcinoma, basal cell or squamous epithelial skin cancer,thyroid papillary carcinoma).
2. Prior treatment with any EGFR-TKIs.
3. Prior treatment with any systemic antitumor therapy for locally advanced or metastatic NSCLC.
4. Previous traditional chinese medicine with an antitumor indication within 2 weeks before the first dose of study drug.
5. Previous major surgery within 4 weeks before the first dose of study drug,or planing to have major surgery during study.

8. Spinal cord compression,symptomatic or unstable central nervous system (CNS) metastases that require the use of steroids .Patients who have a stable CNS status for at least 4 weeks before treatment will be allowed to join the study.
9. Any clinical evidence of serious or uncontrolled systemic disease,including uncontrolled hypertension after drug treatment,active bleeding diatheses, previous or present thrombus,uncontrolled cardiovascular and cerebrovascular diseases.
10. Active infection including hepatitis B,hepatitis C,syphilis and human immunodeficiency virus (HIV).
11. Mean resting corrected QT interval (QTcF) ≥450 msec,obtained from 3 ECGs or any clinically important abnormalities in rhythm,conduction, morphology of resting ECG or left ventricular ejection fraction (LVEF) ≤ 50%,etc.
12. Previous history of interstitial lung disease(ILD),drug-induced interstitial lung disease,history of radiation-induced pneumonia requiring hormone therapy,or clinical evidence of active interstitial lung disease.
13. Any instance that affects the patient's ability to swallow drug or oral malabsorption.
14. Occur any laboratory indicator abnormalities as follow：
* absolute neutrophil count(ANC)\<1,500/mcL
