Brief Summary

This is an open-label phase I/II preliminary study, including dose escalation, dose expansion, and efficacy expansion, to evaluate drug safety, tolerability, PK, and efficacy. The dose escalation study evaluates the IMP's safety, tolerability, and PK in patients with locally advanced or metastatic NSCLC who have experienced disease progression after third-generation EGFR-TKI therapy. The dose expansion study, after 2-3 dose levels are selected based on dose escalation results, further investigates the IMP's safety, tolerability, and PK, explores preliminary efficacy, and determines RP2D in patients with locally advanced or metastatic NSCLC harboring EGFR C797X mutation. The efficacy expansion study evaluates the IMP's safety and efficacy in patients with locally advanced or metastatic NSCLC harboring EGFR C797X mutation.

Experimental:WJ13404 tablets

Dose escalation: 6 dose levels The dose escalation study is proposed to include 6 dose levels: 30, 90, 180, 270, 360, and 480 mg once daily.

Dose-expansion: After the initial data evaluation, the Sponsor and the SMC will select 2-3 dose levels to evaluate drug safety and PK further, explore its preliminary efficacy, and determine RP2D.

Efficacy expansion: The RP2D determined in dose escalation and dose expansion will be applied.

Eligibility Criteria

Inclusion Criteria

1. Aged ≥ 18 years old, male or female;

2. Histologically or cytologically confirmed locally advanced or recurrent/metastatic advanced NSCLC that is inoperable, is subject to progression or intolerability after the standard of care, or is unable to be treated or has not been treated by the standard of care;

3. Dose escalation: patients with EGFR sensitive mutation who have experienced disease progression after third-generation EGFR-TKI therapy;

4. Dose expansion and efficacy expansion: patients with proven EGFR C797X mutation;

5. Patients who agree to provide tumor tissues and blood samples for EGFR mutation analysis (certain patients who are unable to provide qualified tumor tissues may be enrolled once approved by investigators and the Sponsor);

6. At least one measurable lesion as per RECIST v1.1;

7. ECOG PS score of 0-1;

8. Expected survival of more than 12 weeks;

9. Sufficient vital organ functions at screening (requiring no blood transfusion, use of hematopoietic stimulating factor, or use of human albumin preparation within 14 days before screening):

1. ANC ≥ 1.5 × 109/L;

2. Platelet ≥ 100 × 109/L;

3. Hemoglobin > 90 g/L;

4. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) ≤ 2.0 × upper limit of normal (ULN) (in the presence of liver metastasis, ≤ 5 × ULN);

5. Total bilirubin (TBIL) ≤ 1.5 × ULN;

6. Coagulation function (INR) ≤ 1.5 × ULN;

7. Blood creatinine ≤ 1.5 × ULN or creatinine clearance (Ccr, calculated by the Cockcroft-Gault formula) ≥ 45 mL/min;

8. Serum lipase and amylase ≤ 1.5 × ULN;

10. Females with childbearing potential and a negative serum pregnancy test within 7 days before enrollment who agree to use effective contraception during the IMP treatment and 6 months after the last dose. This protocol defines "females with childbearing potential" as sexually mature women who: 1) have not undergone a hysterectomy or bilateral ovariectomy; 2) have not had spontaneous menopause for 24 consecutive months (i.e., no menstrual bleeding at any time within the last 24 consecutive months; amenorrhea after cancer treatment does not indicate infertility). Male patients whose sexual partners are females with childbearing potential must agree to use effective contraception during the study treatment and 6 months after the last dose;

11. Patients who voluntarily participate in this study and have signed the informed consent form after an all-inclusive informed consent process.

Exclusion Criteria

1. Patients who have received systemic anti-tumor therapy within 4 weeks before the first dose, including chemotherapy, targeted therapy, anti-vascular drug therapy, biologic therapy, immunotherapy, radiotherapy, or other IMP therapy; moreover, patients who have received EGFR-TKI targeted therapy may be enrolled if 5 half-lives have passed after discontinuation;

2. Patients who are receiving strong CYP3A inhibitors or inducers; or those who have yet to reach 5 half-lives after discontinuation of a strong inhibitor, or 5 half-lives or 14 days (whichever is longer) after discontinuation of a strong inducer at the time of the first WJ13404 dosing;
