Filter by:The purpose of this study is to compare the efficacy and safety of different concentration gradients of sirolimus in the treatment of Kaposiform hemangioendothelioma.
Background: Some people with human immunodeficiency virus (HIV) are on antiretroviral therapy (ART). Their cells have shown to age faster than expected. This puts them at higher risk for a range of age-related diseases about 10 years sooner than people who do not have HIV. Low bone mineral density (BMD) is common in people with HIV. This means their risk of fractures is increased. People with HIV also have a higher risk for cancers caused by Kaposi's sarcoma herpesvirus (KSHV) than people who do not have HIV. Much of the data on bone loss related to cancer and cancer treatments has been gathered from people who do not have HIV. Researchers want to learn more about the rate of bone loss in people with HIV/AIDS and KSHV associated cancers. Objective: To learn the factors that are linked to BMD loss in people with HIV and KSHV associated cancers from imaging performed as part of NIH studies. Eligibility: Adults with HIV and Kaposi s sarcoma who got ART and cancer chemotherapy at NIH from 1/1/2005 to 12/1/2020. Design: Participants' records will be chosen from studies that were conducted from 1/1/2005 to 12/1/2020. This study will include participants who had at least 2 CT scans. Some participants may have opted out of the future use of their data. If so, their records will not be used. This study will use data collected at NIH. Data taken from CT scans will be used to measure BMD. Study results may be published. This study will last about 2 years.
This phase II trial studies the effect of pomalidomide in treating patients with Kaposi sarcoma. Pomalidomide is a cancer fighting drug that stops the growth of blood vessels, stimulates the immune system, and may kill cancer cells.
This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.
This randomized controlled trial aims to compare guided discontinuation with maintenance treatment of sirolimus in pediatric patients with KHE.
a phase I trial focusing on safety and efficacy of prednison shock plus sirolimus maintenance in treating Kaposiform hemangioendothelioma (KHE) with Kasabach-Merritt phenomenon (KMP)
This phase II trial studies how well ixazomib works in treating patients with Kaposi sarcoma. Ixazomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Background: Kaposi sarcoma (KS) tumors grow on the skin, lymph nodes, lungs, bone, and gastrointestinal tract. KS often affects people with immune deficiencies, such as among people living with HIV or those with prior history of transplant. Researchers want to see if 2 non-chemotherapy drugs can help people with KS. NHS-IL12 triggers the immune system to fight tumors. M7824 blocks the pathways that cancer cells use to stop the immune system from fighting tumors. Objective: To learn if giving NHS-IL12 alone or with M7824 could help the immune system fight KS tumors. Eligibility: People 18 and older with KS that has been treated with chemotherapy or immunotherapy Design: Participants will be screened with some or all of the following: medical history physical exam chest X-ray computed tomography scan blood and urine tests electrocardiogram and echocardiogram skin KS lesion biopsy lung exam gastrointestinal exam All participants will get NHS-IL12 every 4 weeks for up to 96 weeks (or 24cycles). It is injected under the skin. Some participants will also get M7824 every 2 weeks for up to 96 weeks (or 24cycles). It is given through a plastic tube that is put in an arm vein. Participants will complete questionnaires about how KS affects their quality of life. Their KS lesions will be measured and photographed. They will repeat some of the screening tests. They will give saliva samples or additional tissue samples. They will have a lung function test. Their ability to perform their normal activities will be assessed. The treatment duration is up to 96 weeks (or 24cycles) with an option to take NHS-IL12 and/or M7824 until the KS tumors are not responding, or you develop unacceptable side effects. Participants will have follow-up visits 7 and 30 days after treatment ends, then every 3 to 6 months for the next 18 months, then once a year for 3 years.
to evaluate the safety and efficacy of Low-dose sirolimus in Kaposiform Hemangioendothelioma in Chinese children by a prospective, randomized open trial.
Kaposi Sarcoma (KS) is a lymphangioproliferation associated with human herpes virus 8 (HHV8) promoted by immunosuppression. HIV-related KS and iatrogenic posttransplantation KS are treated by immune restoration, in association with local or systemic therapies as chemotherapies if required. Conversely in classic and endemic KS, the underlying relative immunosuppression cannot be directly targeted. Treatment is poorly codified, mostly based on surgery or radiotherapy for localized KS. Most aggressive forms with visceral involvement are treated with chemotherapies or interferon, which give at best 30-60% of transient responses and may not be well tolerated in elderly patients. Talimogene laherparepvec is the first oncolytic immunotherapy approved by the FDA, in metastatic or unresectable melanoma with injectable nodal or cutaneous lesions. It is designed to induce tumor regression of injected lesions through direct lytic effects, and of uninjected lesions through induction of systemic antitumor immunity. In Merkel cell carcinoma (MCC), another virus-induced tumor, treatment with PD-1/PD-L1 axis inhibitors have proven efficacy, thus providing a proof of principle that immunotherapy could be effective in virus-induced tumors. Two cases of metastatic MCC successfully treated with talimogene laherparepvec were recently reported, suggesting that talimogene laherparepvec may also be an effective therapeutic option. Considering the high immunogenicity of viral epitopes in KS tumors, the role of the immune evasion in the development of KS, and the cutaneous manifestations (>90% of patients) that can be easily injected, classic and endemic KS is a good tumor model to be targeted with talimogene laherparepvec. The main objective is to assess whether talimogene laherparepvec is clinically inactive (partial+complete response probability π0<10%) or truly active (partial+complete response probability π1>40%) in classic and endemic Kaposi sarcoma.
