NCT ID: NCT00237185 Completed - Clinical trials for Unresectable or Metastatic Malignant Gastrointestinal Stromal Tumor (GIST)

A Study of the Efficacy and Safety of Imatinib Mesylate in Patients With Unresectable or Metastatic Gastrointestinal Stromal Tumors Expressing C-kit Gene

Start date: June 2000
Phase: Phase 2
Study type: Interventional

In the core study, participants with unresectable or metastatic gastrointestinal stromal tumors expressing c-kit were treated with either 400 mg or 600 mg imatinib mesylate for 3 years. The 10 year extension study allowed participants, who successfully completed the core study, to continue study treatment with imatinib mesylate provided they still benefited from treatment and did not demonstrate safety concerns as per the investigator's opinion.

NCT ID: NCT00237172 Completed - Clinical trials for Gastrointestinal Stromal Tumors

Start date: September 2002
Phase: Phase 2
Study type: Interventional

This is a extension study of CSTI571B1201 study

NCT ID: NCT00171977 Completed - Clinical trials for Gastrointestinal Stromal Tumors

Post-Marketing Clinical Study of Postoperative Adjuvant Therapy With Imatinib Mesylate in Patients With Gastrointestinal Stromal Tumors (GIST)

Start date: July 2004
Phase: Phase 4
Study type: Interventional

This is a multicenter, post-marketing, clinical study evaluating the safety and efficacy of postoperative adjuvant therapy with Imatinib Mesylate in high-risk patients after curative resection of newly diagnosed GIST.Patients will be evaluated for relapse -free survival as measured by the confirmation of tumor recurrence and survival for 3 years after surgery for their primary tumors.

NCT ID: NCT00137449 Completed - Clinical trials for Gastrointestinal Stromal Tumors

Study Of SU011248 Administered On A Continuous Daily Dosing Schedule In Patients With Gastrointestinal Stromal Tumor

Start date: September 2005
Phase: Phase 2
Study type: Interventional

To evaluate the antitumor activity of SU011248 in advanced, imatinib mesylate-resistant gastrointestinal stromal tumor (GIST) when administered on a continuous daily dosing schedule

NCT ID: NCT00135005 Completed - Clinical trials for Gastrointestinal Stromal Tumors

Study of AMN107 With Imatinib in Gastrointestinal Stromal Tumors (GIST)

Start date: August 2005
Phase: Phase 1
Study type: Interventional

This study is an open-label, multicenter, Phase I dose-escalation study of the combination of AMN107 and imatinib (STI571) in patients with imatinib-resistant GIST. This study is designed to determine the Phase II dose of AMN107 and imatinib when administered together in patients with imatinib-resistant GIST, and to characterize the safety, tolerability and pharmacokinetic (PK) profile of this combination.

NCT ID: NCT00117299 Completed - Sarcoma Clinical Trials

PTK787/ZK222584 in the Treatment of Metastatic Gastrointestinal Stromal Tumors Resistant to Imatinib

Start date: September 2004
Phase: Phase 2
Study type: Interventional

This study evaluates the safety and efficacy of a novel tyrosine kinase inhibitor, PTK787/ZK222584, in the treatment of GIST (gastrointestinal stromal tumor) that is resistant to imatinib mesylate (Gleevec). The study participants are required to have histologically confirmed GIST with prior imatinib treatment for metastatic GIST. is administered orally 1250 mg/day. Six patients will first enter the study. If clinical benefit is obtained in >1 of 6 patients, 9 and 30 additional patients will be entered into the protocol in two stages (a maximum of 45 patients will be entered). Patients who benefit from the study treatment will be treated with PTK787/ZK222584 until treatment failure.

NCT ID: NCT00116935 Completed - Sarcoma Clinical Trials

Study Comparing 12 Months Versus 36 Months of Imatinib in the Treatment of Gastrointestinal Stromal Tumor (GIST)

Start date: February 2004
Phase: Phase 3
Study type: Interventional

In this study, patients who have been diagnosed with gastrointestinal stromal tumor (GIST) will be randomly allocated in a 1:1 ratio to receive imatinib (Gleevec) either for 12 or for 36 months following surgery. The study participants are required to have a histologically verified GIST with a high risk of GIST recurrence despite complete removal of all macroscopic GIST tissue at surgery. The high/very high risk of recurrence is defined as one of the following: 1) the largest tumor diameter is over 10 cm; 2) the mitosis count is high (over 10 mitoses per 50 high power microscope fields, HPFs); 3) the largest tumor diameter over 5 cm and the mitosis count is over 5/50 HPFs; 4) tumor spillage has taken place into the abdominal cavity at the time of surgery or following spontaneous tumor rupture. All study participants will receive imatinib 400 mg/day orally, but the duration of imatinib administration will be determined randomly (either for 12 or for 36 months). The study participants will be followed up using blood tests and computed tomography (or MRI) of the abdomen. The computed tomography examinations will be performed at 6 month intervals for a median of 5 years. A total of 280 patients will be entered into the study. The study hypothesis is that adjuvant imatinib may prevent some of the GIST recurrences, and that there may be a difference in the rate of GIST recurrence between the two groups.

NCT ID: NCT00112632 Completed - Clinical trials for Gastrointestinal Stromal Tumor

Imatinib Mesylate in Treating Patients With Locally Advanced Gastrointestinal Stromal Tumor

Start date: February 2005
Phase: Phase 2
Study type: Interventional

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving imatinib mesylate before surgery may shrink the tumor so that it can be removed. PURPOSE: This phase II trial is studying how well imatinib mesylate works in treating patients with locally advanced gastrointestinal stromal tumor.

NCT ID: NCT00103168 Completed - Clinical trials for Gastrointestinal Stromal Tumor

Imatinib Mesylate or Observation Only in Treating Patients Who Have Undergone Surgery for Localized Gastrointestinal Stromal Tumor

Start date: December 2004
Phase: Phase 3
Study type: Interventional

RATIONALE: Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving imatinib mesylate after surgery may kill any remaining tumor cells. It is not yet known whether imatinib mesylate is more effective than observation only in treating gastrointestinal stromal tumor. PURPOSE: This randomized phase III trial is studying imatinib mesylate to see how well it works compared to observation only in treating patients who have undergone surgery for localized gastrointestinal stromal tumor.

NCT ID: NCT00098579 Completed - Clinical trials for Gastrointestinal Stromal Tumor

Doxorubicin Hydrochloride and Alvocidib in Treating Patients With Metastatic or Recurrent Sarcoma That Cannot Be Removed By Surgery

Start date: October 2004
Phase: Phase 1
Study type: Interventional

This phase I trial is studying the side effects and best dose of alvocidib when given with doxorubicin hydrochloride in treating patients with metastatic or recurrent sarcoma that cannot be removed by surgery. Drugs used in chemotherapy, such as doxorubicin hydrochloride and alvocidib, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Alvocidib may also help doxorubicin hydrochloride work better by making tumor cells more sensitive to the drug. Giving more than one drug may kill more tumor cells
