NSCLC
Conditions
Brief summary
This is a phase Ⅰb multi-center clinical study. To explore the preliminary efficacy and safety of Furmonertinib Mesilate at different doses in locally advanced or metastatic NSCLC patients with EGFR exon 20 insertion mutation. The study plans to enroll 30 subjects, including 20 treated patients and 10 treatment-naïve patients. The subjects with disease progression after previous systematic anti-tumor therapy will be randomized to receive Furmonertinib Mesilate 160 mg/day (N=10) or 240 mg/day (N=10), respectively. The treatment-naïve patients do not need to be randomized and all will receive Furmonertinib Mesilate 240 mg/day (N=10) until disease progression, death or intolerability. The primary endpoint is ORR; the secondary study endpoints include DCR, DOR, DepOR, PFS, OS, CNS ORR, safety and the PK profile of Furmonertinib Mesilate and its metabolites (AST5902). In addition, the peripheral blood ctDNA will be collected and analyzed in this study

Inclusion criteria
* Man or woman aged ≥18 years; * Histologically or cytopathologically confirmed primary non-small cell lung cancer (NSCLC) with predominant non-squamous cell histology; * The treated patients must have radiological disease progression following the last anti-tumor therapy; and the treatment-naïve patients must have documented positive EGFR exon 20 insertion mutation by laboratory tests prior to enrollment; * Subjects meeting either of the following conditions (in accordance with the AJCC 8th edition TNM stage classification for lung cancer): * Treated patients: patients with locally advanced (judged by investigators as not suitable for surgery or radiotherapy) or metastatic NSCLC who are confirmed to have radiological or pathological disease progression during or after the last systematic anti-tumor therapy before the first dose of investigational product * Treatment-naïve patients: patients with locally advanced (judged by investigators as not suitable for surgery or radiotherapy) or metastatic NSCLC who have no prior systematic anti-tumor therapy before the first dose of investigational product. If the time from the completion of adjuvant or neoadjuvant therapy to the first disease progression is \> 6 months, the patients will be eligible for enrollment to the study; if it is ≤6 months, the patients will be regarded as treated patients and evaluated in accordance with the criteria for treated patients * Having at least one measurable lesion (in accordance with RECIST1.1). Note: measurable lesion can neither be subject to local therapy as radiotherapy nor used for biopsy in screening period; if there is only one measurable lesion, this lesion will be permitted to be biopsied. However, the baseline radiological examination can be performed for this lesion at least 14 days after biopsy. * Adequate organ function as shown in the laboratory test, including: * Life expectancy \>12 weeks after the first dose of investigational product; * Female subjects of childbearing potential must have a negative serum pregnancy test within 7 days prior to the first dose of investigational product; female subjects of non-childbearing potential may not undergo pregnancy test or contraception. Non-childbearing potential is defined as: 50 years and above, no use of hormone therapy and amenorrhea for at least 12 months; or having received sterilization operation. Female subjects at childbearing age and male subjects agree to take effective contraceptive measures during the study and within 6 months after drug discontinuation; * Being able to understand and voluntarily participate in the study, and sign the informed consent form.
Exclusion criteria
* NSCLC with predominant squamous cell histology, small cell lung cancer or neuroendocrine carcinoma indicated by Histology or cytology test; * Expected to receive other anti-tumor therapy other than the investigational product during the study; * Treatment-naïve patients: having previously received systematic anti-tumor therapy targeting EGFR pathway (marketed drugs or drugs under development, EGFR TKI or antibody) * Treated patients: having previously received systematic anti-tumor therapy with 3rd-generation EGFR TKI (marketed drugs or drugs under development) ; * Having received the following therapies: * Having been irradiated for \>30% bone marrow or a large area within 4 weeks prior to the first dose of investigational product; * Having received major surgery within 4 weeks prior to the first dose of investigational product or plan to receive major surgery during the study with exception of the surgical procedures to establish vascular access, biopsy through mediastinoscopy or thoracoscopy; * Use of a potent CYP3A4 inhibitor within 7 days prior to the first dose of investigational product or a potent CYP3A4 inducer within 21 days prior to the first dose of investigational product; use of the traditional Chinese medicine or traditional Chinese medicine preparation with tumor indication, or traditional Chinese medicine or traditional Chinese medicine preparation with adjuvant anti-tumor effect within two weeks prior to the first dose of investigational product or expected to be required during the study; * Having participated in the clinical trial and received the investigational product or device within 4 weeks or at least 5 half-lives prior to the first dose of investigational product; * Having received other anti-tumor drugs within 14 days prior to the first dose of investigational product; * Concurrent spinal cord compression or symptomatic brain metastasis. Subjects with stable brain metastasis will be eligible. Stable brain metastasis is defined as the patients who have completed regular treatment for brain metastasis, are clinically stable or asymptomatic for at least two weeks and do not need steroid therapy. If the investigator considers there is no indication of immediate radical treatment, patients with asymptomatic brain metastasis will be eligible. * The toxicity caused by previous anti-tumor therapy has not recovered to ≤CTCAE grade 1 (CTCAE 5.0) ( except alopecia, sequelae of previous platinum-related neurotoxicity) or the level specified in the inclusion/
