than three lines of systemic treatment (including at least one chemotherapy or
immunotherapy) for locally advanced or metastatic NSCLC disease; If the completion
time of adjuvant or neoadjuvant treatment is less than or equal to 6 months from the
time of the first disease progression, it is evaluated in accordance with the criteria
for treated patients Treatment-naïve patients t without any systemic anti-tumor
therapy for locally advanced or metastatic NSCLC; If the completion time of adjuvant
or neoadjuvant treatment is more than 6 months from the time of first disease
progression, the patients be eligible for enrollment to the study;
- The Participants should provide enough ctDNA in peripheral blood during the screening
period, and at the same time, they should provide enough advanced tumor tissue
sections as far as possible for central laboratory testing to confirm the mutation
type of EGFR 20 exon (please refer to the manual of central laboratory for details);
- Participants meeting either of the following conditions (in accordance with the AJCC
8th edition TNM stage classification for lung cancer):
- 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: 1)Absolute
neutrophil count (ANC) = 1.5 × 109/L; platelet count (PLT) = 100 × 109/L; hemoglobin
(HGB) = 90 g/L; 2)Serum total bilirubin (TBIL) = 1.5 × upper limit of normal (ULN),
AST and ALT = 2.5 × ULN (total bilirubin = 3 × ULN, AST and ALT = 5 × ULN in patients
with hepatic metastasis); 3)Creatinine clearance (CrCL) = 50 ml/min (using Cockcroft-
Gault formula); Prothrombin time (PT) = 1.5 × ULN;
- ECOG PS score 0-1 at screening, no obvious exacerbation of disease within 2 weeks
prior to screening;
- 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:
Any potential participant who meets any of the following criteria will be excluded
fromparticipating in the study:
- 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;
- Treated patients: having previously received systematic anti-tumor therapy with
3rd-generation EGFR TKI (marketed drugs or drugs under development) ;
1)Therapeutic drugs (such as dzd9008, tak788, jnj-372, bocitinib, etc.) for EGFR 20
exon insertion mutation; 2)The third generation of EGFR TKI (marketed or in research
drug); 3) The first and second generation EGFR TKI (marketed drugs or drugs in
Research) targeting the insertion mutation of EGFR 20 exon had objective remission;
- Having received the following therapies:
1. Having been irradiated for >30% bone marrow or a large area within 4 weeks prior
to the first dose of investigational product;
2. 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;
3. 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;
4. 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/exclusion criteria;
- Unstable pleural effusion or peritoneal effusion with obvious symptoms; those with
stable clinical symptoms for at least 14 days after drainage of pleural effusion or
ascites will be eligible;
- Having a history of other malignant tumor, or other concurrent malignant tumors
(except those that have undergone radical operation and have no recurrence within 5
years post operation, e.g., cervical carcinoma in situ, basal cell carcinoma of skin
and papillary thyroid carcinoma);
- Previous interstitial lung disease (ILD), drug-induced interstitial lung disease,
radiation pneumonitis requiring steroid therapy; or having the clinical manifestations
of suspected interstitial lung disease;
- Having severe or uncontrolled systemic disease requiring treatment that is considered
by investigators as ineligible for the study, including hypertension, diabetes,
chronic heart failure (NYHA Functional Classification III-IV), unstable angina
pectoris, myocardial infarction within one year, active hemorrhagic disease, etc.;
- Left ventricular ejection fraction (LVEF) <50% on echocardiography;
- Clinically significant prolonged QT interval or other arrhythmia or clinical status
considered by investigators that may increase the risk of prolonged QT interval; for
example, QTc>470 ms on ECG at resting state, complete left bundle branch block, degree
III atrioventricular block, congenital long QT syndrome, serious hypokalemia, or
current use of drugs that may lead to prolonged QT interval;
- Serious gastrointestinal dysfunction, or disease that may affect the intake,
transportation or absorption of investigational product;
- Known hepatitis B virus (positive HBsAg), hepatitis C virus (positive HCV Ab) or human
immunodeficiency virus (positive HIV antibody) infection;
- Infectious disease requiring intravenous medication;
- Known history of mental disease or drug abuse, and currently having an attack or still
taking drugs;
- Known or suspected allergy to Furmonertinib or other components of its preparation;
- Female subjects or female partners of male subjects who are pregnant or lactating, or
