Glumetinib combined withFruquintinib in the treatment of MET amplification or protein overexpression in third-line unresectable metastatic colorectal cancer: evaluation of efficacy and safety

Вмешательства

• Препарат Glumetinib Combined with Fruquintinib
  Fruquintinib: 3mg, po.qd, d1-14，q3w; Guemitinib: Grade 1:200mg, po, qd, q3w; Grade 2:250mg, po, qd, q3w; Phase I: The dose of Glumetinib (200 mg → 250 mg) is dynamically adjusted using the "3+3 dose-escalation rule" to determine the optimal dose of Fruquintinib. Phase II: The RP2D (Recommended Phase II Dose) of Glumetinib identified in Phase I is continued in combination with Fruquintinib.

• Absolute neutrophil count (ANC) ≥1.5×10\^9/L, platelet count ≥75×10\^9/L and hemoglobin 80 g/L, white blood cell count (WBC) ≥3.0×10\^9/L (corrected by no blood transfusion, no blood products, no use of granulocyte colony-stimulating factor or other hematopoietic stimulating factor within 14 days before laboratory tests);
• Liver and kidney functions: Serum creatinine ≤1.5 times the upper limit of normal value or creatinine clearance rate ≥50mL/min; AST and ALT ≤2.5 times the upper limit of normal values (for patients with liver invasion, ≤5 times the upper limit of normal values); Serum total bilirubin ≤2 times the upper limit of normal value (for patients with liver invasion ≤2.5 times the upper limit of normal value);
• The activated partial thromboplastin time (APTT), International normalized ratio (INR), and prothrombin time (PT) are ≤1.5 times the normal upper limit value.
• Women of childbearing age must undergo a pregnancy test (serum) within 7 days before enrollment, with a negative result, and be willing to use appropriate contraceptive methods (such as intrauterine devices \[IUD\], contraceptives or condoms) during the test and 6 months after the last administration of the test drug; The serum pregnancy test must be negative within 7 days before enrollment in the study, and the subjects must be non-lactating. Male subjects who should agree that contraceptive measures must be adopted during the study period and within 6 months after the end of the study period;
