Inclusion criteria
Inclusion criteria: 1. Provision of informed consent prior to any study-specific procedures; 2. Age 18-75 years; 3. ECOG performance status of 0 or 1 with no deterioration within the 2 weeks prior to enrollment, and a life expectancy of >=12 weeks; 4. Histologically or cytologically confirmed non-squamous non-small cell lung cancer; 5. Assessed as having unresectable or inoperable locally advanced non-squamous non-small cell lung cancer suitable for definitive radiotherapy (Stage III according to AJCC 9th edition TNM staging); 6. Presence of EGFR uncommon mutations (excluding 19del, L858R, T790M) confirmed by genetic testing in a tertiary grade A hospital; 7. No prior systemic anti-tumor therapy or radiotherapy for locally advanced non-small cell lung cancer before the first dose of the study drug, including chemotherapy, biologic therapy, targeted therapy, immunotherapy, or investigational drug therapy; 8. At least one accurately measurable lesion according to RECIST 1.1, which has not been previously irradiated and was not biopsied during the screening period. If a subject has only one measurable lesion, biopsy of that lesion is permitted, provided the baseline imaging is performed at least 14 days after the biopsy; 9. Female subjects must use highly effective contraception (see restrictions) for at least 2 weeks prior to the first dose, have a negative pregnancy test, must not be breastfeeding at the time of treatment initiation, OR must meet at least one of the following criteria at screening to demonstrate the absence of childbearing potential: a)Postmenopausal, defined as age over 50 years and amenorrhea for at least 12 months after cessation of all exogenous hormonal treatments b)For women aged 50 years or younger, amenorrhea for 12 months or more after cessation of exogenous hormone therapy and luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels within the institutional postmenopausal range c)Irreversible surgical sterilization documented by hysterectomy, bilateral oophorectomy, or bilateral salpingectomy, but excluding tubal ligation; 10. Male subjects must be willing to use barrier contraception; 11. Ability to comply with the study protocol and follow-up procedures, and capable of oral medication intake.
Exclusion criteria
Exclusion criteria: 1. Pathological type is pulmonary squamous cell carcinoma or small cell lung cancer; 2. Known history of hypersensitivity to the active or inactive excipients of firmonertinib, or to drugs with a similar chemical structure or class to the investigational drug; 3. Confirmed presence of EGFR exon 19 deletion or exon 21 L858R mutation; 4. Presence of metastatic disease, or assessed as unsuitable for definitive radiotherapy; or unable to undergo definitive radiotherapy due to extensive tumor volume resulting in normal tissue radiation doses exceeding dose constraints; 5. NSCLC involving the superior sulcus, large cell neuroendocrine carcinoma (LCNEC), or sarcomatoid tumor; 6. Prior to the first dose of the study drug, patients who have received any of the following treatments: • Any prior EGFR-TKI therapy; • Patients who have received intrapleural infusion therapy; • Major surgery within 28 days prior to the first dose of study drug (In China, major surgery is defined according to the Level 3 and Level 4 surgeries specified in the "Administrative Measures for the Clinical Application of Medical Technologies" implemented on May 1, 2009; see Appendix 5 for details); • Treatment with strong CYP3A4 inhibitors or inducers within 7 days prior to the first dose, or patients who require continued use of these drugs during the study period (see Appendix 6 for drug list); • Treatment with traditional Chinese medicine or Chinese patent medicine for anti-tumor indications within 7 days prior to the first dose, or patients who require continued use of these drugs during the study period; • Concurrent use of medications known to prolong the QTc interval or that may induce Torsade de Pointes, and which require continued administration during the study period (see Appendix 8 for drug list); • Discontinuation of other investigational drugs within less than 5 half-lives or 2 months (whichever is longer) prior to the first dose; 7. Toxicities from prior anti-tumor therapy have not recovered to 1000 copies/mL); 12. History of inter
