122 Clinical Trials for Various Conditions
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).

The purpose of this study is to find out why cancers develop in HIV-positive patients. Cancer is a leading cause of death in AIDS patients. Common cancers in HIV-infected patients include Kaposi's sarcoma (KS) and non-Hodgkin's lymphoma (NHL), a cancer of the immune system. Risk factors include certain chemicals, viruses, and perhaps even anti-HIV drugs. Doctors would like to find out which risk factors are most important and how they relate to cancer in AIDS patients.
Primary: To evaluate the safety, toxicity, and antitumor activity of two doses of interferon alfa-2b (IFN-alpha) combined with a fixed dose of didanosine (ddI) in patients with Kaposi's sarcoma associated with HIV infection. Secondary: To evaluate the effects of combined IFN-alpha and ddI treatment on HIV expression and markers of immune function. Previous studies have shown that IFN-alpha can induce regression of Kaposi's sarcoma and suppression of HIV in some patients. Although various trials using IFN-alpha in combination with the nucleoside analogue zidovudine have demonstrated a high degree of antitumor activity and evidence of HIV suppression, the overlapping toxicity (primarily neutropenia) of these two agents has proven dose-limiting. The toxicity profile of ddI suggests that this drug may be better tolerated than zidovudine when combined with IFN-alpha.
To evaluate the safety and toxicity of combination therapy for AIDS-associated Kaposi's sarcoma with zidovudine (AZT) and two kinds of interferon alpha. The two kinds are interferon alpha (IFN-A) and interferon alpha-2A (recombinant) (IFN-A2A). To define the pharmacokinetics of AZT and IFN-A or AZT and IFN-A2A when given in combination. To define the maximum tolerated dose (MTD) of each drug in combination and to define doses to be used in Phase II trial. AZT has been found to be effective against the effects of HIV in vitro (test tube) and both interferons have shown antiviral and antitumor effect on Kaposi's sarcoma. It is reasonable to assume that a synergism and an enhanced antitumor response may be seen with combination therapy. A study to evaluate the safety and effectiveness of AZT in the combination with IFN-A2A is warranted.
To evaluate the safety and efficacy of liposomal doxorubicin hydrochloride ( DOX-SL ) alone or in combination with bleomycin and vincristine in the long-term treatment of AIDS-related Kaposi's sarcoma. To determine whether the 3-drug combination enhances progression-free survival and quality of life. Liposomal formulations of chemotherapeutic agents increase drug accumulation in tumors, which permits disease palliation at relatively low doses and thus decreases some of the dose-limiting toxicity. Multi-agent therapy is considered to be more effective than single-agent therapy; therefore, DOX-SL will be combined with bleomycin and vincristine.
To study the natural course of AIDS related Kaposi's sarcoma and to determine the usefulness and safety of weekly administration of small doses of doxorubicin. Doxorubicin is one of the most active of all antitumor agents but at currently used doses toxicity is common. When small doses are administered on a weekly schedule, the toxicity of the drug appears to be reduced.
To study the safety and maximum tolerated dose (MTD) of combined chemotherapy when it is administered to patients with advanced Kaposi's sarcoma together with one of two different doses of zidovudine (AZT). The combination of AZT and chemotherapy may be effective in treating the tumor as well as preventing the life-threatening infections when used for patients with AIDS and Kaposi's sarcoma. The MTD of combined chemotherapy is being determined so that the information will be available for future studies, when the relative effectiveness of the two doses of AZT has been learned.
To determine the toxicity and response to treatment with cytotoxic chemotherapy using doxorubicin (Adriamycin), bleomycin, and vincristine (DBV) for advanced AIDS-related Kaposi's sarcoma in combination with either didanosine (ddI) or zalcitabine (dideoxycytidine; ddC). AIDS patients with extensive Kaposi's sarcoma require treatment with effective cytotoxic agents to reduce the tumor burden, and they also require treatment with other possibly effective antiretroviral agents such as ddI or ddC to ameliorate (delay) the development of opportunistic infections.
To assess the toxicity, tumor response rate, and effect on quality of life of daily low-dose etoposide administered for 7 consecutive days every other week in patients with AIDS-related Kaposi's sarcoma that has relapsed or progressed after systemic chemotherapy. Etoposide may be at least as, or even more, effective and less myelotoxic when given in low doses over prolonged periods of time.
