This is an interventional treatment trial for Non-small Cell Lung Carcinoma focused on measuring non-small cell lung carcinoma Read More

Inclusion Criteria:

1. Male or female ≥ 18 years old;
2. Life expectancy ≥ 12 weeks;
3. Eastern Cooperative Oncology Group (ECOG) performance status 0-1;
4. Patients with histologically or cytologically confirmed diagnosis of inoperable locally advanced or recurrent/metastatic NSCLC with EGFR mutations. Patients must have progressed from or be intolerant to or be unfit for standard treatment.
5. For dose escalation: patients with documented EGFR mutation that have progressed on or after third-generation EGFR-TKI. In addition, other lines of therapy may have been given.
6. For dose expansion and Phase II: patients with EGFR C797S mutation confirmed prior to enrollment on tissue or blood samples with radiological documentation of disease progression from first-generation, second-generation or third-generation EGFR-TKIs. In addition, other lines of therapy may have been given;
7. For dose expansion and Phase II, patients must have at least one measurable tumor lesion per RECIST v1.1 criteria as per Investigator's assessment;

8. Adequate bone marrow, liver, and renal function:

   • Blood: Absolute neutrophil count (ANC) ≥ 1.5 × 109/L (1500/mm3), platelets count ≥ 100 × 109/L, hemoglobin ≥ 9 g/dL (90 g/L) (must not have received transfusion or granulocyte colony-stimulating factor within 2 weeks of screening tests and procedures);
   • Liver function: total bilirubin ≤ 1.5 × ULN; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3.0 × ULN; if liver metastases exist, AST and ALT ≤ 5.0 × ULN; for patients with documented Gilbert's syndrome, total bilirubin ≤ 3.0 × ULN;
   • Renal function: Estimated glomerular filtration rate (eGFR) ≥ 50 mL/min (calculated by CKD-EPI);
9. All acute toxic effects of any prior antitumor therapy or surgery must have resolved to baseline or ≤ CTCAE Grade 1 (with the exception of alopecia);
10. For women with childbearing potential, serum pregnancy test will be performed within 7 days before dosing, with a negative result, and they must be non-lactating; all patients should take medically recognized contraceptive measures throughout the treatment period and 3 months after the last dose (see section Error! Reference source not found.);
11. Men with partners of childbearing potential willing to use adequate contraceptive measures during the study and for 90 days after the last dose of study medication.
12. Patients must have fully understood and voluntarily signed informed consent form (ICF).

Exclusion Criteria:

1. Presence of another active primary malignant tumors;
2. Unstable, symptomatic primary CNS tumors/metastasis or leptomeningeal metastases which are not suitable for enrollment, as judged by investigators. A patient can be enrolled if his/her clinical condition is stable and imaging evidence does not show disease progression within 2 weeks prior to the first dose, and who is off corticosteroid, anticonvulsant or mannitol treatment for longer than 2 weeks prior to the first dose.
3. Treatment with the most recent therapy (e.g., chemotherapy, immunotherapy, targeted therapy, radiation therapy, investigational therapy/agent) within 4 weeks or approximately 5 half-lives, whichever is the longer, before the first dose. (If sufficient wash-out time has not occurred due to schedule or PK properties, an alternative appropriate wash-out time based on known duration and time to reversibility of drug related adverse events could be agreed upon by the sponsor and investigators);
4. Gastrointestinal disorders that would affect oral swallowing or the investigators judge the absorption of the study drug will be interfered;
5. Use of strong or moderate CYP3A inhibitors or inducers within 7 days prior to the first dose;
6. Autologous (within 3 months) or allogeneic (within 6 months) organ or stem cell transplantation prior to the first dose; any major surgery or severe trauma (except biopsy sampling) within 4 months prior to the first dose;
7. Palliative radiation therapy within 2 weeks prior to the first dose;
8. Patients who have active viral hepatitis B (HBV) infection (exception: HBV DNA ≤ 500 IU/mL and has been stable for longer than 4 weeks);
9. Patients who have active infections that required systemic therapy within 1 week prior to the first dose;

10. Any of the following cardiac conditions within the last 6 months:

    Unexplained or cardiovascular cause of presyncope or syncope, tachycardia, ventricular fibrillation, or sudden cardiac arrest. Prolonged corrected QT interval [mean resting corrected QT interval QTcF > 450 msec for males or > 470 msec for females from 3 electrocardiogram (ECG)];

11. Any > CTCAE Grade 1 prior to the first dose;
12. Medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease, any uncontrolled systemic disease, and other serious illnesses;
13. Patients with deep venous thrombosis, pulmonary embolism or any other serious thromboembolism within 3 months prior to the first dose (implantable venous access-port, catheter-related thrombosis or superficial venous thrombosis is not considered as "serious" thromboembolism);
14. The presence of drug abuse and medical, psychological, or social conditions that do not permit compliance with the protocol or will not be available for protocol-required study visits or procedures.
