Brief Summary:
the primary objective of this study is to assess the efficacy (progression-free survival,PFS) of DCC-2618 (ripretinib, ZL-2307) and sunitinib in patients with advanced gastrointestinal stromal tumors after treatment with imatinib. This study will enroll approximately 98 subjects in around 18 sites in China mainland, and all subjects will be receiving DCC-2618 or Sunitinib in equal chance as treatment.

Primary Outcome Measures :
  1. PFS assessed by independent central review [ Time Frame: 7 months after enrollment is completed in study ]
    To assess the efficacy (progression-free survival [PFS], by independent radiologic review)of DCC-2618 (ripretinib, ZL-2307) and sunitinib in patients


Secondary Outcome Measures :
  1. objective response rate(ORR) [ Time Frame: 7 months after enrollment is completed in study ]
    To assess objective response rate (ORR) by independent radiologic review using RECIST v1.1-GIST-specific criteria

  2. DCR [ Time Frame: 7 months after enrollment is completed in study ]
    To assess disease control rate (DCR) by independent radiologic review

  3. PFS assessed by investigator [ Time Frame: 7 months after enrollment is completed in study ]
    To assess PFS based on Investigator assessment

  4. overall survival (OS) [ Time Frame: 7 months after enrollment is completed in study ]
    To assess overall survival (OS)

  5. To compare the safety profile of DCC-2618 (ripretinib, ZL-2307) to the safety profile of sunitinib by using AE/SAE/AESI collection during study. [ Time Frame: 7 months after enrollment is completed in study ]
    • Incidence of treatment emergent adverse event (TEAE), adverse event of special interest (AESI) and serious adverse event (SAE); severity of adverse event will be assessed (based on NCI CTCAE 5.0);
    • Incidence of adverse events resulting in dose adjustment of the study drug or termination of the study

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Male or female patients ≥18 years of age.
  • Histological diagnosis of advanced GIST and capability of providing tumor tissue sample (the interval between tumor tissue collection and signing of informed consent form should be less than 3 years). Otherwise, biopsy is required.
  • Provide molecular test report with KIT/PDGFRA mutation status prior to randomization.
  • Patients must have progressed on imatinib or have documented intolerance to imatinib. Subjects must have discontinued imatinib treatment 10 days prior to the first dose of the study drug. All prior imatinib treatments will be considered as first-line (such as imatinib adjuvant therapy and imatinib dose increase).
  • ECOG PS of 0-2.
  • Female patients of childbearing potential must have a negative serum beta-human chorionic gonadotropin (β-hCG) pregnancy test at screening.
  • Patients of reproductive potential must agree to follow the contraception requirements.
  • At least 1 measurable lesion according to the "RECIST v1.1-GIST-specific Criteria" (non-nodal lesions must be ≥1.0 cm in the long axis or ≥ double the slide thickness in the long axis) ; obtaining radiographic image results within 28 days prior to the first dose of study drug.
  • Good organ function and bone marrow reserve function, including:

    • Neutrophil count ≥ 1,000/µL
    • Hemoglobin ≥ 8 g/dL
    • Platelet count ≥ 75,000/µL
    • Total bilirubin ≤ 1.5 × the upper limit of normal (ULN)
    • AST and ALT ≤ 3×ULN, and AST and ALT≤ 5×ULN in the presence of hepatic metastases
    • Creatinine clearance ≥ 50 mL/min (based on Cockcroft-Gault estimation Formulas for calculation)
    • Prothrombin time (PT), international normalized ratio (INR) or partial thromboplastin time ≤ 1.5 × ULN. Patients on a stable, maintenance regimen of anticoagulant therapy for at least 30 days prior to study drug administration may have PT/INR measurements >1.5 × ULN if, in the opinion of the investigator, the patient is suitable for the study. An adequate rationale must be provided to the sponsor prior to randomization.
  • Resolution of all toxicities from prior therapy to ≤Grade 1 (or baseline) within 1 week prior to the first dose of study drug (excluding alopecia and ≤ Grade 3 clinically asymptomatic lipase, amylase, and creatine phosphokinase laboratory abnormalities).
  • Patient is capable of understanding and complying with the protocol. Subjects should sign the written informed consent before any study-related procedures were performed.

Exclusion Criteria:

  • Treatment with any other line of therapy in addition to imatinib for advanced GIST. Imatinib-containing combination therapy in the first-line treatment should not be enrolled.

  • Use of known substrates or inhibitors of breast cancer resistance protein (BCRP) transporters within 14 days or 5 x the half-life (whichever is longer) prior to the first dose of study drug.
  • Major surgeries (e.g. abdominal laparotomy) within 4 weeks of the first dose of study drug; all major surgical wounds must be healed and free of infection or dehiscence before the first dose of study drug.
  • Any other clinically significant comorbidities, such as uncontrolled pulmonary disease, active infection, or any other condition, which in the judgment of the investigator, could compromise compliance with the protocol, interfere with interpretation of the study results, or predispose the patient to safety risks.
  • Known human immunodeficiency virus or hepatitis C infection only if the patient is taking medications that are excluded per protocol, hepatitis B virus (HBV) DNA > 2000 IU/ml or > 104 copies/ml.
  • Female patients who are pregnant or lactating or who plan to become pregnant during the study treatment period.
