A Phase II Trial of the DNA Methyl Transferase Inhibitor, Guadecitabine (SGI-110), in Children and Adults With Wild Type GIST,Pheochromocytoma and Paraganglioma Associated With Succinate Dehydrogenase Deficiency and HLRCC-associated Kidney Cancer
Stopped early · Phase 2
Conditions studied: Paraganglioma, Gastrointestinal Stromal Tumors, Carcinoma, Renal Cell, Renal Neoplasms, Pheochromocytoma
In brief
Background: 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). Objective: To learn if SGI-110 causes GIST tumors to shrink or slows their growth. Also to test how it acts in the body. Eligibility: People ages 12 and older who have GIST, PHEO/PGL, or HLRCC that has not responded to other treatments Design: Participants will be screened with: * Physical exam * Urine tests * Computed tomography (CT) or magnetic resonance imaging (MRI), or fluorodeoxyglucose (FDG)-positron emission tomography (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. ...

You may not qualify if…
- Patients with any one the following will be excluded:
- Ongoing radiation therapy, chemotherapy, hormonal therapy directed at the tumor, immunotherapy, or biologic therapy, including investigational agents for their disease.
- History of allergic reactions to SGI-110 or decitabine.
- Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, symptomatic pulmonary disease or psychiatric illness/social situations that would limit compliance with study requirements.
- Pregnant or breastfeeding
- Pregnant women are excluded from this study because SGI-110 is a derivative of decitabine which has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with SGI-110, breastfeeding should be discontinued if the mother is treated with SGI-110.
- These potential risks may also apply to other agents used in this study.
- Any evidence of severe or uncontrolled systemic disease, active infection, active bleeding diatheses, or renal transplant, including any patient known to have hepatitis B, hepatitis C, or human immunodeficiency virus (HIV) will be excluded. Patients with HIV who have adequate cluster of differentiation 4 (CD4) count, not requiring antiretroviral medication, may be enrolled.
- Patients who, in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study.
