Inclusion criteria

Inclusion criteria: 1. Male or female patients =18 years of age at the time of informed consent 2. Histologic diagnosis of GIST 3. Patients must have progressed on imatinib, sunitinib, and regorafenib or have documented intolerance to any of these treatments despite dose modifications. 4. ECOG PS of 0 to 2 at screening. 5. Able to provide an archival tumor tissue sample if no anticancer therapy was administered since the sample was collected; otherwise, a fresh tumor tissue sample is required prior to the first dose of study drug. 6.

The patient is capable of understanding and complying with the protocol and has signed the informed consent document. A signed informed consent form must be obtained before any study-specific procedures are performed. 9. At least 1 measurable lesion according to modified RECIST Version 1.1 (non-nodal lesions must be =1.0 cm in the long axis or =double the slide thickness in the long axis) within 21 days prior to the first dose of study drug. 10. Adequate organ function and bone marrow reserve as indicated by the following laboratory assessments performed at screening. • Absolute neutrophil count =1000/µL • Hemoglobin =8 g/dL • Platelet count =75,000/µL • Total bilirubin =1.5 x the upper limit of normal (ULN) • Aspartate transaminase and alanine transaminase =3 x ULN (=5x ULN in the presence of hepatic metastases) • Serum creatinine =1.5 x ULN or creatinine clearance =50 mL/min based on either urine collection or Cockcroft Gault estimation. • Prothrombin time (PT), or international normalized ratio (INR), and partial thromboplastin time =1.5 x 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 x 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. 11. 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). Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 60 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 60

Exclusion criteria

Exclusion criteria: 1. Treatment with anticancer therapy, including investigational therapy, or investigational procedures within 14 days or 5 x the half-life (whichever is longer) prior to the first dose of study drug. For prior biological therapies, eg, monoclonal antibodies with a half-life longer than 3 days, the interval must be at least 28 days prior to the first dose of study drug. 2. Prior treatment with DCC-2618 3. Prior or concurrent malignancy whose natural history or treatment have the potential to interfere with the safety or efficacy assessment of DCC-2618. Patients receiving adjuvant cancer treatment are not eligible if those medications are potentially active against GIST or excluded per protocol (refer to Section 5.12.3 of the study protocol). 4. Patient has known active central nervous system metastases. 5. New York Heart Association class II - IV heart disease, active ischemia or any other uncontrolled cardiac condition such as angina pectoris, clinically significant cardiac arrhythmia requiring therapy, uncontrolled hypertension or congestive heart failure. 6. Arterial thrombotic or embolic events such as cerebrovascular accident (including ischemic attacks) or hemoptysis within 6 months before the first dose of study drug. 7. Venous thrombotic events (eg, deep vein thrombosis) or pulmonary arterial events (eg, pulmonary embolism) within 3 months before the first dose of study drug. Patients with venous thrombotic events =3 months before the first dose of study drug on stable anticoagulation therapy are eligible. 8. 12-lead electrocardiogram (ECG) demonstrating QT interval corrected by Fridericia’s formula >450 ms in males or >470 ms in females at screening or history of long QT interval corrected syndrome. 9. Left ventricular ejection fraction (LVEF) 4 weeks prior to the first dose of study drug, all surgical wounds must be healed and free of infection or dehiscence. 14. 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 interpreta

Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the efficacy (progression-free survival [PFS]) of DCC-2618 by independent radiologic review in patients with advanced gastrointestinal stromal tumors (GIST) who have received prior therapies;Secondary Objective: Key Secondary Objective: • To assess objective response rate by independent radiologic review Secondary Objectives: • To assess other parameters of efficacy, including but not limited to time to progression (TTP) and overall survival (OS) • To assess the PD/PK relationship of DCC-2618 • To assess the robustness of efficacy using a sensitivity analysis • To assess improvement of disease-related symptoms and quality of life • To assess the safety of DCC-2618;Primary end point(s): PFS based on independent radiologic review using modified RECIST (1; Appendix 17.1 of the protocol). Modified RECIST criteria includes: • No lymph nodes chosen as target lesions; enlarged lymph nodes followed as non-target lesions; • No bone lesions chosen as target lesions; • Positron emission tomography not acceptable for radiological evaluation; • A progressively growing new tumor nodule within a pre-existing tumor mass must meet the following criteria to be considered as unequivocal evidence of progression according to the modification of RECIST Version 1.1: (a) the lesion is at least 2 cm in size and definitively a new active GIST lesion (eg, enhancing with contrast or other criteria to rule out artefact); or (b) the lesion has to be expanding on at least 2 sequential imaging studies.;Timepoint(s) of evaluation of this end point: The primary endpoint of PFS (reported in weeks) is defined as the interval between the date of randomization and the earliest documented evidence of disease progression based on the independent radiologic review, or death due to any cause. Patients who undergo surgical resection of target or non-target lesions, who have received other anticancer treatments, or patients who do not have a documented date of progression or death d

Secondary

MeasureTime frame
Secondary end point(s): Key Secondary Efficacy Endpoint: • Objective response rate (confirmed CR + confirmed PR) Secondary Efficacy Endpoints: • TTP based on independent radiologic review • OS • Time to best response • PFS based on Investigator assessment • Quality of life as determined by changes from baseline in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer 30-item and EuroQol 5-Dimension 5-Level • Disease control rate (complete response [CR] + partial response [PR] + stable disease) at 12 weeks Safety: Treatment-emergent adverse events, adverse events of special interest, serious adverse events, dose reduction or discontinuation of study drug due to toxicity; and changes from baseline in ECOG PS, vital signs, ECGs, LVEF, dermatologic examinations, and clinical laboratory parameters. Pharmacokinetics (PK): • Correlation of PK with efficacy/safety • Population PK ;Timepoint(s) of evaluation of this end point: Objective response rate: to be assigned a status of a CR or PR, changes in tumor measurements must be confirmed by repeat assessments that must be performed at least 4 weeks after the criteria for response are first met. Patients with unknown or missing response will be treated as non responders, that is, they will be included in the denominator when calculating the proportion. Time to confirmed response (CR or PR) (reported in weeks) is defined as the interval between the date of first dose of study medication and the earliest date of first documented confirmed CR or confirmed PR. Patients who do not have a confirmed PR or CR will be censored at the date of the last adequate assessment.
