About this trial
The purpose of this research is to test if mutations (changes in DNA) in exons (segment of DNA or RNA containing information that has the instructions for making proteins) in the KIT gene can be used to predict the body's response to standard of care treatment.
Eligibility criteria
Qualifiers
Patients who are ≥ 18 years of age.
Patients who have histologically confirmed metastatic or unresectable GIST. Unresectable GIST must be confirmed to be unresectable by an experienced surgeon.
Patients who received imatinib prior treatment regimens, including adjuvant therapy, with objective disease progression, inadequate clinical benefit, or intolerance. Additionally, disease progression or intolerance to other systemic therapies including investigational agents and radiotherapy is allowed. Patients who experienced intolerance to prior therapies must have objective disease progression prior to enrollment.
Patients who have an Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0 to 2.
Disqualifiers
Patients who have received prior treatment with sunitinib or regorafenib.
Patients who have received more than 2 different prior tyrosine kinase inhibitor (TKI) treatment regimens. If a patient receives the same TKI more than once sequentially (eg, imatinib followed by a period without systemic therapy and retreatment with imatinib), that will be counted as a single TKI treatment regimen.
Patients who are known to be KIT wild type.
Patients who received any systemic anticancer therapy within 2 weeks before. Prior radiotherapy to major organs within 2 weeks of admission, or focal radiotherapy, such as to bones, limbs, or other areas not involving major organs, within 3 days.
