Brief Summary:
This study evaluates the combination of entacapone and imatinib in the treatment of gastrointestinal stromal Tumors who have progressed on the setting of at least Imatinib and Sunitinib. 5 participants will be included in this open-label observatory study.

Condition or disease Intervention/treatment Phase
Gastrointestinal Stromal Tumor, Malignant Drug: Entacapone Drug: Imatinib Mesylate Early Phase 1

Detailed Description:

Most patients with Metastatic/unresectable Gastrointestinal stromal tumors will progress on the treatment of tyrosine kinase inhibitor(TKI) including Imatinib and Sunitinib.

Entacapone and imatinib can each inhibit the role of v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog(KIT) which is a kind of transmembrane receptor tyrosine kinase promoting the clonal proliferation and growth of GIST cells, but they do so by different mechanisms.

Entacapone has been approved from China Food and Drug Administration(cFDA) for controlling the symptom of Parkinson' s disease in the combination with levodopa. Recently, entacapone was identified to be an inhibitor of Fat mass and obesity-associated protein(FTO) enzyme, which was reported as the first N6-methyladenosine (m6A) demethylase of eukaryotic messenger RNA(mRNA). Entacapone can inhibit the transcriptional level of KIT mRNA leading to the decreased expression of KIT protein.

Imatinib mesylate, an oral multiple TKI targeting the KIT-oncoprotein, was the standard first-line therapy of c-KIT-mutated GISTs. Imatinib can prohibit the activation of mutated c-KIT tyrosine kinase and then impede the kinase cascade of c-KIT signal pathway.

Arm Intervention/treatment
Experimental: Entacapone & Imatinib mesylate

Entacapone 200mg tablet by mouth, three times a day and then increasing to 400mg tablet by mouth, three times a day until disease progression, intolerable toxicity, or withdrawal of informed consent, whichever occurs first.

And Imatinib mesylate 400mg tablet by mouth, once a day until disease progression, intolerable toxicity, or withdrawal of informed consent, whichever occurs first.

Drug: Entacapone
Entacapone tablet

  • Comtan
  • Comtess

Drug: Imatinib Mesylate
Imatinib Mesylate tablet
Other Name: Gleevec




Primary Outcome Measures :
  1. Objective response rate(ORR) [ Time Frame: 30 days, 90days, 180days ]
    the total proportion of patients with reduction in tumor burden of a predefined amount. The ORR is the sum of complete response(CR)+partial responses(PR) per Response Evaluation Criteria in Solid Tumors(RECIST) v1.1

  2. Disease control rate(DCR) [ Time Frame: 30 days, 90days, 180days ]
    the total proportion of patients who demonstrate a response to treatment. The DCR is the sum of complete response(CR)+partial responses(PR)+ stable disease(SD) per Response Evaluation Criteria in Solid Tumors(RECIST) v1.1

Criteria

Inclusion Criteria:

  1. Able to provide written informed consent and can understand and comply with the requirements of the study and the schedule of assessments.
  2. Age ≥ 18 years on the day of signing the informed consent form (or the legal age of consent in the jurisdiction in which the study is taking place).
  3. Expected life span > 12 weeks.
  4. Histologically confirmed disease which is currently metastatic/unresectable gastrointestinal stroma tumor(GIST) of c-KIT E11 mutation genotype.
  5. Patients received imatinib as the first-line treatment and no progression within the first 6 months(no primary resistance to imatinib ). With disease progression following treatment with at least imatinib and sunitinib.
  6. Patients must be able to provide archival tumor tissues (approximately 4 [at least 2] unstained Formalin Fixed and Paraffin Embedded Tissues (FFPET)slides) for biomarker analysis to assess the expression of FTO and c-KIT protein.
  7. At least 1 measurable lesion (the longest diameter≥ 10mm). Note: Computed Tomography(CT) abdomen and pelvis with contrast including peritoneum, or positron emission tomography/computed tomography(PET/CT) performed skull base to knees or whole body before the first day of entacapone.
  8. Eastern Cooperative Oncology Group-performance status(ECOG PS) ≤ 2,or 3(the symptoms were definitely caused by GIST itself).
  9. Adequate hematologic and end-organ function, as defined by the following laboratory results (obtained ≤ 28 days prior to the first day of entacapone):

    • Absolute neutrophil count (ANC) ≥ 1.5 × 10 9 /L, hemoglobin ≥ 80 g/L and platelets ≥80 × 10 9 /L.
    • Total serum bilirubin ≤ 2.5 × upper limit of normal (ULN); Aspartate and alanine aminotransferase (AST and ALT) ≤ 2.5× ULN.
    • Estimated creatinine clearance rate≥ 60 mL/min(According to the formula of Cockcroft-Gault).
  10. Females of childbearing potential must be willing to practice highly effective method of birth control for the duration of the study, and at least 120 days after the last dose of entacapone or imatinib. Non-sterile males must be willing to use a highly effective method of birth control for the duration of the study and at least 120 days after the last dose of entacapone or imatinib.

Exclusion Criteria:
