Overview
Brief Summary
This multicenter study evaluates the efficacy and safety of furmonertinib 160mg versus furmonertinib 80mg plus chemotherapy (carboplatin + pemetrexed) as first-line treatment for EGFR-mutated NSCLC patients with brain metastases. It aims to determine which approach is more effective and safer.

Inclusion Criteria
- •IInclusion Criteria
- •Aged 18 to 75 years (male or female)
- •Histopathologically confirmed, unresectable, and non-radiocurable newly -diagnosed locally advanced or metastatic lung adenocarcinoma
- •Confirmed by local laboratory to have one of the following EGFR mutations: -19Del or L858R (single or mixed mutations are allowed)
- •Treatment-naive for locally advanced (not suitable for surgery/radiotherapy per investigator) or metastatic NSCLC; adjuvant/neoadjuvant therapy completed \>6 months before first progression is allowed (≤6 months is considered pretreated)
- •At least one measurable tumor lesion per RECIST 1.1 (lesions previously treated with radiotherapy are excluded; if only one measurable lesion exists, biopsy is allowed but baseline imaging must be performed ≥14 days after biopsy)
- •Confirmed stable and asymptomatic brain metastases
- •Sufficient organ function (per laboratory tests): ANC ≥1.5×10⁹/L, PLT ≥100×10⁹/L, HGB ≥90g/L; TBIL ≤1.5×ULN, AST/ALT ≤2.5×ULN (for liver metastasis: TBIL ≤3×ULN, AST/ALT ≤5×ULN); CrCL ≥50 ml/min (Cockcroft-Gault formula)
- •ECOG performance status 0-2 (no significant disease deterioration in 2 weeks before screening)
- •Expected survival \>12 weeks after first dose
Exclusion Criteria
- •NSCLC with predominantly squamous cell histology, small cell lung cancer, neuroendocrine carcinoma, or other non-adenocarcinoma histologies
- •Concurrent positive for other driver genes (ALK fusion, ROS1 fusion, RET rearrangement, BRAF mutation, NTRK fusion, MET mutation, KRAS mutation); TP53, RB1, and BRAC mutations are excluded
- •Expected to receive other anti-tumor therapies during the trial
- •Major surgery (except vascular access or biopsy) within 4 weeks before first dose or planned during the trial
- •Use of CYP3A4 strong inhibitor within 7 days or strong inducer within 21 days before first dose; use of anti-tumor Chinese medicine within 2 weeks before first dose or planned during the trial
- •Participation in other clinical trials (investigational drug/device) within 4 weeks or 5 half-lives before first dose
- •Use of other anti-tumor drugs within 14 days before first dose
- •Spinal cord compression or symptomatic leptomeningeal metastasis
- •Toxicity from previous anti-tumor therapy not recovered to ≤CTCAE Grade 1 (except alopecia or platinum-induced peripheral neuropathy)
- •Symptomatic or unstable pleural/peritoneal effusion (stable ≥14 days after drainage is allowed)
