Gastrointestinal Stromal Tumor clinical trials at UCSD

This is a 2-arm, randomized, open-label, international, multicenter study comparing the efficacy of ripretinib to sunitinib in GIST patients who progressed on or were intolerant to first-line anticancer treatment with imatinib. Approximately 426 patients will be randomized in a 1:1 ratio to ripretinib 150 mg once daily (continuous dosing for 6 week cycles) or sunitinib 50 mg once daily (6 week cycles, 4 weeks on, 2 weeks off).

This phase II trial studies nivolumab and ipilimumab in treating patients with rare tumors. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial enrolls participants for the following cohorts based on condition: 1. Epithelial tumors of nasal cavity, sinuses, nasopharynx: A) Squamous cell carcinoma with variants of nasal cavity, sinuses, and nasopharynx and trachea (excluding laryngeal, nasopharyngeal cancer [NPC], and squamous cell carcinoma of the head and neck [SCCHN]) B) Adenocarcinoma and variants of nasal cavity, sinuses, and nasopharynx (closed to accrual 07/27/2018) 2.

Funding Source - FDA OOPD FDA-approved products for patients with unresectable or metastatic GIST include therapies such as imatinib and sunitinib. Although there are FDA-approved products for the treatment of advanced/metastatic GIST, these therapies are known to be ineffective in the SDH-mutant/deficient subtype and no known effective therapies exist. The purpose of this study is to investigate SDH-Mutant/Deficient Gastrointestinal Stromal cancer's response to the drug Temozolomide (TMZ) and aim to improve patient outcomes. Temozolomide is approved by the FDA for the treatment of newly diagnosed glioblastoma multiforme (GBM) and refractory anaplastic astrocytoma cancers. Temozolomide is considered experimental because it is not approved by the FDA for the treatment of SDH-Mutant/Deficient Gastrointestinal Stromal Tumor.
