Active clinical trials for "Gastrointestinal Stromal Tumors"

This randomized phase II trial studies how well nivolumab with or without ipilimumab works in treating patients with gastrointestinal stromal tumor that has spread to other places in the body or cannot be removed by surgery. Monoclonal antibodies, such as nivolumab and ipilimumab, interfere with the ability of tumor cells to grow and spread.

A randomized, open, two-period, two-sequence crossover trial design used to assess the pharmacokinetics and safety of Sunitinib Malate Capsules in healthy volunteers under fed condition, and compare the bioequivalence of Sunitinib Malate Capsules produced by Pfizer and Chia Tai Tianqing Pharmaceutical Group Co., Ltd, respectively.

This is a Phase 1, open-label, first-in-human (FIH) dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antitumor activity of DCC-2618, administered orally (PO), in adult patients with advanced malignancies. The study consists of 2 parts, a dose-escalation phase, and an expansion phase. All active patients (from both dose-escalation and expansion phases) will then transition into an extension phase.

The purpose of this study is to determine a maximum tolerated dose and/or recommended phase 2 dose of a combination of imatinib and BYL719 in the treatment of 3rd line GIST patients.

Background: -Some people with wild-type gastrointestinal stromal tumors (WT-GIST) have a deficiency in one of their proteins called succinate dehydrogenase (SDH). Vandetanib is a cancer drug that has been approved to treat thyroid cancer and has been used with some success in other tumors that have a similar loss of SDH. Researchers want to see if this drug can also decrease tumor growth in people with WT-GIST. Objectives: -To test whether the study drug will benefit people with WT-GIST. Eligibility: -Adults and children 3 years old and older with WT-GIST. Design: Researchers will test participants tumor tissue to confirm it is the wild type of GIST. Participants will be screened with a medical history, physical exam, and blood tests. They will also have electrical recording of the heart (Eastern Cooperative Oncology Group (ECOG)) and scans of the tumor. Participants will take the study drug in 28-day cycles. Their doctor will decide how many cycles they can complete. They will take the study drug once every day and record it in a diary. On Day 14, they will also visit their doctor to look for side effects. Before cycles 2, 3 and 4, participants will have a physical exam, urine tests, blood pressure check, and blood tests. These tests will then be done periodically for as long as they are in the study. Before cycle 4, scans will be done to check the size of the cancer. Most of these will be repeated every 3-6 cycles. When they stop taking the study drug, participants will return to the clinic for a physical exam and blood tests.

Patients with metastatic or locally advanced gastrointestinal stromal tumors (GIST) who develop resistance against the two hitherto approved drugs for this disease, the tyrosin kinase inhibitors (TKIs) imatinib and sunitinib, have a poor prognosis. Sometimes a further response may be achieved by other drugs, mainly other TKIs, which have been explored in different studies but not yet have been approved for clinical use. Pazopanib is a TKI inhibiting the tyrosin kinases KIT, PDGFRA, and VEGF 1-3, all of which have important roles in the pathogenesis of GIST. Theoretically, it may function in GIST, and it deserves investigational trials. The drug is approved for metastatic renal cancer and is relatively well tolerated. In this trial (SSG XXI), the disease control rate (DCR) = (CR+PR+SD) after 12 weeks of treatment will be assessed as the primary endpoint, and at the same time trough levels will be measured. Secondary endpoints include ORR, PFS, toxicity, and disease control rate in relation to trough level week 12 and in relation to the primary mutation of the tumor (if known). The goal is to include 72 patients in the trial, which is open and single arm.

This phase I trial studies the side effects and best dose of dasatinib when given together with ipilimumab in treating patients with gastrointestinal stromal tumors or other sarcomas that cannot be removed by surgery or have spread to other places in the body. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as ipilimumab, can block tumor growth in different ways by targeting certain cells. Giving dasatinib together with ipilimumab may be a better treatment for patients with gastrointestinal stromal tumors or other sarcomas.

The objective is to compare the efficacy and safety of masitinib at 12 mg/kg/day to sunitinib at 50 mg/day in the treatment of patients with gastro-intestinal stromal tumor (GIST) after progression with imatinib.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of brostallicin in treating patients who have locally advanced or metastatic soft tissue sarcoma that has not responded to one previous chemotherapy regimen.
