Filter by: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 evaluate a multi-dose regimen of SGN-30, a novel chimeric monoclonal antibody (mAb), in patients with refractory or recurrent CD30+ hematologic malignancies. This is a single-arm, open-label phase I/II study designed to define the toxicity profile, pharmacokinetic (PK) profile, and anti-tumor activity of a multi-dose regimen of SGN-30 in patients with refractory or recurrent CD30+ hematologic malignancies. The phase I study will be a modified dose escalation of SGN-30. Based on preclinical pharmacology and toxicokinetics (TK) and the first use in human single-dose phase I study, SGN-30 will be administered on a weekly schedule. An initial dose of 2 mg/kg will escalate until the maximum tolerated dose (MTD) has been reached or until a weekly dose of 12 mg/kg is achieved.
The purpose of this study is to develop imaging techniques to determine the density of blood vessels and the amount of blood flow in Kaposi s sarcoma (KS) tumors. KS tumors depend on the formation of new blood vessels for their growth. Some experimental therapies for KS are directed at reducing the amount of blood vessels and blood flow in these lesions. Measurement of blood vessel density and blood flow in these lesions could be useful in evaluating the effectiveness of both standard and experimental treatments for this disease. Patients 18 years of age or older with Kaposi's sarcoma involving the skin may be eligible for this study. Participants will have photographs taken of their lesions and will undergo three imaging procedures (described below) at the beginning of the study (baseline) and then about once every 3 months or so while on the study (up to 2 years) to compare the test results over time. (Imaging may be done at more or less frequent intervals depending on the findings.) A small amount of blood (less than a tablespoon) will be drawn the day of each imaging procedure. Laser Doppler imaging This technique measures the amount of blood flow in KS lesions by scanning the lesions with a low-power laser beam. Each lesion takes about 3 minutes to scan. The imaging may be done before and after a blood pressure cuff around the arm is inflated for a short time (usually less than 30 seconds). Multi-spectral imaging This technique uses light to measure the total blood volume in each lesion and how much oxygen is in the blood. Oxygen is carried to the body s cells by a protein in red blood cells called hemoglobin. The light on the multi-spectral imaging instrument is absorbed differently depending on whether the hemoglobin has oxygen attached to it or not. It takes about 2 minutes to scan each lesion. Infrared thermal imaging This test uses a special camera to take digital infrared pictures of the skin. Images formed of the temperature of the KS lesions are used to assess blood flow in the lesions. This imaging takes about 1 minute per lesion. ...
This study will investigate patterns of Kaposi's sarcoma herpes virus (KSHV) in the United States and its potential impact on the U.S. population. KSHV is a newly discovered virus that is strongly associated with Kaposi's sarcoma and primary effusion lymphoma. The high prevalence of KS and KSHV among HIV-infected homosexual men suggests sexual contact as a primary mode of transmission. Reports of non-sexual transmission in parts of Africa and the Mediterranean where Kaposi's sarcoma is endemic, and the identification of viral DNA in saliva and other bodily fluids, however, indicate the virus is also transmitted non-sexually. This study will: - Compare the prevalence of KSHV among different demographic groups in the United States - Examine the association between KSHV and high risk behaviors such as drug use (marijuana and cocaine), sexual behavior (age at first sexual intercourse and number of sexual partners), and medical risk factors (herpes simplex virus II, hepatitis B and hepatitis C) - Estimate the prevalence of KSHV in the United States. Data and blood samples for the study will be taken from the NHANES III survey. NHANES is a program of periodic surveys conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The survey is designed to provide national estimates of health status for the United States non-institutionalized civilian population by means of household interviews, standardized physical examinations, and blood sample collection and testing. NHANES III-the seventh in a series of national examination studies-was conducted from 1988 to 1994. This study will use the HANES data to identify risks associated with a KSHV-positive blood test in the survey population. The study plans to include all 19,754 participants (67% of the 29,314 participants originally examined) for whom blood samples were collected and remain available.
Phase I/II trial to study the effectiveness of BMS-275291 in treating patients who have HIV-related Kaposi's sarcoma. Drugs such as BMS-275291 may stop the growth of Kaposi's sarcoma by stopping blood flow to the tumor.
RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill the tumor cells. Combining chemotherapy with interleukin-12 may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining liposomal doxorubicin with interleukin-12 in treating patients who have AIDS-related Kaposi's sarcoma.
RATIONALE: Herpesvirus is found in Kaposi's sarcoma lesions in most patients; it is therefore possible that the herpesvirus has a role in causing Kaposi's sarcoma. Cidofovir is an antiviral drug that acts against many types of herpesvirus, and may be an effective treatment for Kaposi's sarcoma. PURPOSE: Phase II trial to study the effectiveness of cidofovir in treating patients with Kaposi's sarcoma with or without HIV infection.
RATIONALE: Interleukin-12 may kill tumor cells by stopping blood flow to the tumor and by stimulating a person's white blood cells to kill their tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of interleukin-12 in treating patients with AIDS -related Kaposi's sarcoma.
RATIONALE: Thalidomide may kill cancer cells by stopping the growth of new blood vessels to the tumor. PURPOSE: Phase II trial to study the effectiveness of thalidomide in treating patients with HIV-associated Kaposi's sarcoma.
