Active clinical trials for "Castleman Disease"

Background: - Kaposi's sarcoma-associated herpes virus (KSHV)-associated multicentric Castleman disease (KSHV-MCD) is caused by a herpes virus known as KSHV. This disease can also cause several other cancers, including Kaposi sarcoma. People with KSHV-MCD often have symptoms like fever, weight and muscle loss, and fluid in the legs or abdomen. Tocilizumab may be able to block the chemicals in the body that cause KSHV-MCD symptoms. Researchers want to test this drug and other anti-virus drugs to find the best combination of drugs to treat KSHV-MCD. Objectives: - To test the effectiveness of tocilizumab with and without other anti-virus drugs for KSHV-MCD. Eligibility: - People at least 18 years of age who have KSHV-MCD and have certain symptoms and blood abnormalities caused by their KSHV-MCD. Design: Participants will be screened with a medical history and physical exam. They will also have blood tests, and a skin biopsy. Participants will have tocilizumab injections every 2 weeks for up to 12 weeks. They will provide daily blood samples for the first 3 days of treatment. After the sixth dose, participants will be monitored for 4 weeks to check for possible side effects. Those whose KSHV-MCD does not improve or worsens during the study may have tocilizumab combined with two other anti-virus drugs, zidovudine and valganciclovir. These drugs are pills that will be taken four times a day for 5 days out of every 2 weeks. Blood, urine, and saliva samples will be collected throughout the study.

This open-label, single center study will provide RoActemra/Actemra (tocilizumab) to a maximum of 4 patients with Multicentric Castelman's Disease who have demonstrated benefit from RoActemra/Actemra in study MRA004US (Chugai Pharma USA) without major toxicities or significant adverse events. Patients will receive their most effective maintenance dose until disease progression or significant toxicity occurs.

Development, validation of a novel symptom burden scale to assess and quantify the burden experienced by people living with Idiopathic Multicentric Castleman Disease (iMCD).

The purpose of this study is to evaluate of the study of different CNTO 328 doses and schedules and to see if CNTO 328 has any effect on Non-hodgkin's Lymphoma, Multiple Myeloma or Castleman's disease.

The purpose of this study is to evaluate the long-term safety of siltuximab in patients with multicentric Castleman's disease (MCD).

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of suramin in treating patients who have refractory or relapsed multiple myeloma or Castleman's disease.

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.

The purpose of this study is to use agnostic genomic evaluation using whole exome sequencing (WES) of a variety of rare hematologic diseases grouped under rare blood diseases and its variants to further elucidate the understanding of the chemistry of these disorders and identify potential actionable mutations that can be targeted with therapies in the context of clinical trials.

Background: - The chemotherapy combination DA-EPOCH-RP includes the drugs etoposide (E), prednisone (P), vincristine (O), cyclophosphamide (C), doxorubicin (H), rituximab (R), and pomalidomide (P). Researchers want to see if including pomalidomide will help people with two rare lymphomas. Objectives: - To study the safety and efficacy of the chemotherapy drugs DA-EPOCH-RP. Eligibility: - Adults at least 18 years old. They must have primary effusion lymphoma or large cell lymphoma arising from Kaposi sarcoma Herpesvirus-associated multicentric Castleman disease. Design: Participants will be with screened with blood tests, scans, spinal tap, and bone marrow sample. They may have skin or lymph node samples taken and fluid removed from around some organs. Participants will have breathing and eye tests. A camera may take pictures inside their body. Participants will take pomalidomide alone by mouth for up to 21 days. Then they will get rituximab by intravenous (IV) catheter, which is a small tube that goes into a vein.. Participants will have an IV inserted in an arm or chest vein to get the IV chemotherapy drugs, at the same time the will take pomalidomide by mouth for 5 days. They will get DA-EPOCH-RP in 21-day cycles. Most people will have 6 cycles. They will get 4 study drugs by IV for 5 days and 2 others by mouth for 5 days. They will get daily filgrastim injections in the skin until white blood counts are acceptable For 2 days of some cycles, methotrexate will be injected into the spinal fluid. After completing EPOCH-RP, some participants who have Kaposi sarcoma will be prescribed pomalidomide for 3-weeks, followed by a one week break, for up to 12 months. Participants will repeat the blood tests often. They will also have repeated medical history, physical exam, urine and stool tests, and pictures of any rashes associated with these lymphomas. Participants will have several follow-up visits over 4 years.

The purpose of the study is to learn whether people who are experiencing an MCD (multicentric Castleman's Disease) flare will improve after taking valganciclovir. MCD is a type of inflammatory disease associated with Human Herpesvirus 8 (HHV-8). Valganciclovir is FDA approved for treating a different type of Human Herpesvirus, but not approved for the treatment of HHV-8. It is therefore considered experimental in this study.
