Filter by:Background: Kaposi sarcoma (KS) is a type of tumor caused by the Kaposi sarcoma herpesvirus. KS usually affects the skin, but lesions can also appear in the lymph nodes, lungs and digestive tract. KS is most common in people with compromised immunity, but it also appears in otherwise healthy people. Researchers want to understand more about how KS develops, why it may recur, and how it affects the immune system and organs. Objective: To learn more about the natural history of KS. Eligibility: People aged 18 years and older with KS. Design: Participants will be screened. They will have a physical exam with blood tests. They will have an imaging scan. They may need a new biopsy: Tissue samples may be cut from their tumor. Their ability to perform normal activities will be assessed. Participants will visit the clinic to have their KS evaluated. In addition to the imaging scans and other tests performed during screening, procedures may include: Eye exam. Ultrasound exam of the heart (electrocardiogram). Collection of saliva and urine samples. Biopsies of the skin or lymph nodes. Swabs of the anus and cervix. Photographs of skin lesions. Removal of fluid samples from the space around the lungs, intestine, or heart. The evaluation visit will be repeated 5 more times over 18 months and then yearly for up to 10 years. Participants will follow their standard treatment for KS during the study.
Evaluating the efficacy of sirolimus (compared to standard therapy alone) in the treatment of dilated cardiomyopathy infected with Kaposi Sarcoma-associated virus -- a multicenter randomized controlled study.
Participants of this study will have a diagnosis of a solid tumor cancer that has come back to its original location or spread beyond its original location (advanced), came back (relapsed) or worsened (refractory) after standard treatments, or no standard treatments are available for the participants' cancer. The purpose of this study if to find the highest dose of MQ710 that causes few or mild side effects in participants with a solid tumor cancer diagnosis.
This study collects blood and tissue samples for research of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS)-related cancers. Collecting blood and tissue samples and studying biomarkers in the laboratory may help doctors to learn how are biologic or genetic factors related to HIV and cancers that occur commonly in people living with HIV.
This is a phase 1b, open label, single arm study evaluating the safety and tolerability of the drug dostarlimab in combination antiretroviral therapy (cART) refractory HIV-associated Kaposi Sarcoma (KS), a rare type of cancer usually seen in people with the HIV infection. Dostarlimab is a type of immunotherapy, and is a monoclonal antibody that has been designed to inhibit the receptor programmed death-1 (PD-1). One of the two ligands for PD-1 has been shown to be upregulated in KS patients, the PDL-1 ligand. By preventing PDL-1 form binding to PD-1, dostarlimab increases the body's immune response to attack more cancer cells. The safety profile of dostarlimab in this specific cancer has not been explored. The primary aim of this study is therefore to provide confirmatory evidence of safety of dostarlimab in KS patients and to preliminary evaluate its effects on HIV reservoirs and assess how it causes its anti-cancer effects through studying tumour tissue before and after treatment. This study will be conducted in two parts and will recruit a total of up to 20 patients. Upon completion of screening investigations inclusive of a fresh tumour biopsy within a 28-days window, patients will receive dostarlimab at the fixed dose of 500 mg dose every 3 weeks for the first 4 doses followed by a fixed 1000 mg dose every 6 weeks. Treatment will be continued until loss of clinical benefit, unacceptable toxicity, patients' withdrawal or completion of a total of 48 weeks of treatment. Part 1 will consist of 6 patients being dosed and observed for toxicity for 21 days following first dose. A trial steering committee will evaluate any treatment related adverse events (AEs) and dose-limiting toxicities (DLTs) reported before deciding on whether to continue onto part 2, where a further 14 patients may be enrolled.
This study is being done to understand how many people with HIV (PWH) present for cancer care across the AIDS Malignancy Consortium in the United States and if there are reasons that some PWH choose to participate, or not in cancer clinical trials. Optional quality of life surveys will be used to learn more about how HIV and cancer and HIV and cancer treatment affect people.
To research and explore the antibody protection and immune memory after vaccination in children with KHE during sirolimus administration. To explore the feasibility (safety and efficacy) of vaccination in a timely manner during the administration of sirolimus in children with KHE. To search for back-up plans for vaccination regimens for KHE patients taking sirolimus in children who do not respond to primary vaccination.
Phase II, open label, multicentric, proof-of-principle basket trial in patients with malignant tumors of the skin amenable to intratumoral injection, and in a curative or neoadjuvant or palliative intention.
The purpose of this study is to compare the efficacy and safety of different doses of sirolimus in the maintenance treatment of kaposiform hemangioendothelioma.
Solid organ transplant candidates will undergo serological screening for HHV8 at time of listing and transplantation. In the event of a recipient/donor mismatch R-/D+ or in the presence of a seropositive recipient (R+), blood levels of HHV8 DNA will be monitored together with specific IGRA for HHV8.
