Active clinical trials for "Sarcoma, Kaposi"

This randomized phase I/II clinical trial is studying the side effects and best dose of gamma-secretase/notch signalling pathway inhibitor RO4929097 when given together with vismodegib and to see how well they work in treating patients with advanced or metastatic sarcoma. Vismodegib may slow the growth of tumor cells. Gamma-secretase/notch signalling pathway inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving vismodegib together with gamma-secretase/notch signalling pathway inhibitor RO4929097 may be an effective treatment for sarcoma.

The purpose of this study is to determine the clinical response to daily Indinavir oral administration in association with a conventional chemotherapy based on cycles of systemic Vinblastine +/- Bleomycin in patients affected by advanced classical (non HIV-associated) Kaposi's sarcoma

Background: The drug liposomal doxorubicin is approved by the U.S. Food and Drug Administration (FDA) for the treatment of Kaposi's sarcoma (KS). A second drug, bevacizumab, is a biologic agent (such as antibodies, interleukins, and vaccines) that stops abnormal blood supply to tumors. Bevacizumab is approved by the FDA, in combination with other drugs, for the treatment of breast cancer, colon cancer, and lung cancer. Researchers are now studying the combination of liposomal doxorubicin with bevacizumab as a novel approach to the treatment of advanced KS. Researches will be measuring KS tumor responses to this combination to determine whether the drugs might have anti-KS activity. Objectives: To estimate the overall response rate (ORR) of six cycles of liposomal doxorubicin combined with bevacizumab in patients with advanced KS. To evaluate the safety of the regimen and to estimate the complete response rate after six cycles, the median number of cycles needed to obtain a partial response, and the 12-month progression-free survival. Eligibility: Patients 18 years or older with relatively severe acquired immune deficiency syndrome (AIDS)-related KS or patients with KS unrelated to AIDS or human immunodeficiency virus (HIV) infection, whose KS that can be evaluated for potential response to therapy and meet a number of other criteria. Women who are pregnant or breastfeeding are not eligible. Other ineligibility criteria include surgery within 4 weeks, chemotherapy within 3 weeks, heart disease, hemoptysis (coughing up blood), or gastrointestinal bleeding. Design: Researchers will conduct the following tests before the start of the study: Physical examination and a detailed medical history. A biopsy. Blood and urine tests. Treatment will include two phases, an induction phase and a maintenance phase: Induction phase dose: Intravenous (IV) bevacizumab 15 mg/kg once, followed 7 days later by liposomal doxorubicin mg/m2 and bevacizumab every 3 weeks for six cycles. Maintenance phase dose: IV bevacizumab every 3 weeks for 11 cycles. Monitoring will include a review of side effects, physical exam (including blood pressure), and blood and urine samples; following the induction phase, the patient will receive a multi gated acquisition scan and electrocardiography (EKG) to record electrical activity in the heart. Research tests include blood and saliva samples, additional biopsies (optional), and noninvasive imaging. Treatment is stopped if any of the following occur: completion of 1 year of therapy, progressive KS, patient preference, or unacceptable toxicity. Post-treatment evaluations include clinic visits every 3 months or as needed up to 2 years, and blood and saliva samples (for research).

This phase II trial studies how well halofuginone hydrobromide works in treating patients with human immunodeficiency virus (HIV)-related Kaposi's sarcoma. Halofuginone hydrobromide ointment may stop the growth of Kaposi's sarcoma by stopping blood flow to the tumor.

This study will examine the safety and effectiveness of the experimental drug bevacizumab for treating both non-acquired immune deficiency syndrome (AIDS) and AIDS-associated Kaposi's sarcoma (KS). KS tumors depend on the formation of new blood vessels for their growth. Bevacizumab is an antibody to a protein called vascular endothelial growth factor (VEGF) that is produced by the body and is involved in blood vessel growth. Bevacizumab may block the action of VEGF, and thus help shrink KS lesions. Patients 18 years of age and older with Kaposi's sarcoma that is restricted to the skin and is not life threatening may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), chest x-ray, and, if needed, imaging studies to evaluate internal tumors. Participants will receive bevacizumab intravenously (by vein) once a week for 2 weeks and then every 3 weeks at the National Institutes of Health (NIH) Clinical Center. The first infusion takes about 90 minutes, the second takes about 60 minutes, and subsequent infusions take about 30 minutes. Infusions may take longer, however, if the drug is better tolerated at a slower infusion rate. Patients will be evaluated with the following tests and procedures: Physical examination, assessment of drug side effects, measurement of KS lesions, and photographs of lesions once a week for the first 6 weeks of therapy, and then every 3 weeks. cluster of differentiation 4 (CD4) cell counts and human immunodeficiency virus (HIV) viral load in HIV-positive patients every 12 weeks. Biopsies of lesions: upon entering the study, at week 12, and at the time of a response of the tumor to therapy or at the end of treatment, if treatment ends at week 18 or later. Additional biopsies, if requested. (Additional biopsies are not required.) Other procedures, such as computed tomography (CT) or magnetic resonance imaging (MRI) scans, if medically indicated. Patients may continue bevacizumab therapy indefinitely if they are benefiting from it, as long as they have no substantial toxicity or other conditions that would cause them to stop receiving it and the protocol remains open.

The purpose of this study is to see if it is safe and effective to use IM862 to treat Kaposi's sarcoma (KS) in AIDS patients.

To evaluate the safety and anti-Kaposi's sarcoma activity of ritonavir.

To study the toxicity and efficacy of IV mitoxantrone hydrochloride (Novantrone) in AIDS-related Kaposi's sarcoma.

To examine the safety and efficacy of two doses of vesnarinone in patients with AIDS-related Kaposi's sarcoma.

To assess toxicity and determine the MTD of intravenous TNP-470 administered weekly in patients with AIDS-related Kaposi's sarcoma. To assess pharmacokinetics and tumor response of the drug. Since evidence shows that neovascularization is important in the development of Kaposi's sarcoma, drugs that inhibit angiogenesis, such as TNP-470, may be of benefit in patients with the disease.
