Wild-type gastrointestinal stromal tumor (GIST) is a cancer in the esophagus, stomach, or intestines. It does not respond well to standard chemotherapy or radiation therapy. Most people with GIST are treated with imatinib. But it may not work in many children with GIST. Researchers think the drug SGI-110 may help treat people with GIST, pheochromocytoma and paraganglioma (PHEO/PGL), or kidney cancer related to hereditary leiomyomatosis and renal cell carcinoma (HLRCC).
To learn if SGI-110 causes GIST tumors to shrink or slows their growth. Also to test how it acts in the body.
People ages 12 and older who have GIST, PHEO/PGL, or HLRCC that has not responded to other treatments
Participants will be screened with:
- Physical exam
- Urine tests
- CT or MRI, or FDG-PET scan: A machine takes pictures of the body.
- Blood tests
Participants will be injected with SGI-110 under the skin each day for 5 days. This cycle will repeat every 28 days. The cycles repeat until their side effects get too bad or their cancer gets worse.
Participants will have tests throughout study:
- Physical exam and blood and urine tests before each cycle
- Blood tests on days 1, 7, 14, and 28 of the first cycle.
- Scans before cycle 1 and then every other cycle.
- Questionnaires about their pain and quality of life
- Tumor biopsy for those 18 and older: A needle removes a small piece of tumor.
After they stop treatment, participants will have a final visit. This includes an evaluation of their health, pain, and quality of life.

Experimental: Arm 1
SGI-110 administered subcutaneously at 45mg/m2/day x 5 days on a 28-day cycle
Drug: SGI-110 (guadecitabine)
SGI-110 will be administered subcutaneously at 45mg/m2/day x 5 days on a 28-day cycle. Cycles may be repeated until there is evidence of tumor progression clinically or by RECIST v1.1 or there is intolerable toxicity that is not alleviated by dose reduction.
- Assess clinical activity of SGI-11 using RECIST [ Time Frame: After the first 4 weeks, then every 8 weeks ]Efficacy
