Active clinical trials for "Immune System Diseases"

The work proposed herein aims to provide the first prospective, randomized comparative efficacy data between Melphalan and BEAM treatment regimen in the Multiple Myeloma (MM) patient population. The risk of such a study is deemed reasonable and ethical since: a) previous works have closely examined the safety and toxicity of the BEAM regimen and the doses to be delivered in this protocol are well below the toxicity levels; b) phase III trials of BEAM have provided reasonable data regarding the efficacy in lymphomas c) Early, retrospective data suggests that BEAM may be efficacious in MM however due to the lack of prospective controlled randomized clinical trial, there is adequate equipoise regarding its efficacy and moreover its comparative efficacy in relation to Melphalan and; D) there are known limitations in the standard-of-care for MM, Melphalan, namely, relatively low rates of complete response at the time of Autologous stem-cell transplantation (ASCT) and poor progression free survival.

This is a single center, open-label ,phase 1/2 study to evaluate the safety and efficacy of targeted CD19/CD22 chimeric antigen receptor engineered T cell immunotherapy (CART) in the treatment of CD19/CD22 positive Relapsed or Refractory B-Cell Acute Lymphoblastic Leukemia.

To assess if using the hypoglycemic clamp and functional magnetic resonance imaging (fMRI) scanning in hypoglycemia unaware and aware T1DM patients and healthy controls have showed distinct differences in patterns of brain responses. In particular, T1DM patients who are aware of hypoglycemia (T1DM-Aware) have greater activity in sensory integration brain regions (e.g. parietal lobe and caudate nucleus) in response to hypoglycemia, whereas hypoglycemia unaware T1DM patients (T1DM-Unaware) show no detectable changes in brain reward regions during hypoglycemia.

The trial is a global, multi-center safety and efficacy trial of epcoritamab, an antibody also known as EPKINLY™ and GEN3013 (DuoBody®-CD3xCD20). The trial consists of 3 parts: a dose-escalation part (Phase 1, first-in-human (FIH)) an expansion part (Phase 2a) a dose-optimization part (Phase 2a)

This phase II trial studies how well obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy work in treating patients with grade I-IIIa follicular lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Umbralisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Chemotherapy drugs, such as cyclophosphamide, doxorubicin, vincristine, prednisone, and bendamustine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy will work better in treating patients with grade I-IIIa follicular lymphoma.

The trial assess the maximum tolerated dose of a single-dose of Brentuximab Vedotin added to standard BeEAM chemotherapy (comprising Bendamustin, Etoposide, Cyclophosphamide and Melphalan) before autologous stem cell transplantation in CD30+ malignant lymphomas.

This is a randomized, multi-center,phase III study to evaluate the ability of thalidomide maintenance therapy to prolong relapse-free survival in diffuse large B cell lymphoma(DLBCL).

This study will evaluate the effect of CYP2C19 and ABCB1 genes on pharmacokinetics of lansoprazole in children with mild gastroesophageal reflux (GER) and uncontrolled asthma. It will determine if genotype-guided lansoprazole dosing of lansoprazole improves GER and asthma control.

This phase I trial studies the side effects and best dose of palbociclib when given alone and in combination with sorafenib, decitabine, or dexamethasone in treating patients with leukemia that has come back (recurrent) or that does not respond to previous treatment (refractory). Palbociclib, sorafenib, and decitabine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving palbociclib alone and in combination with sorafenib, decitabine, or dexamethasone may work better in treating patients with recurrent or refractory leukemia.

Background: In nearly all people with human immunodeficiency virus (HIV) infection, immunity cannot either control or eradicate the infection. There are good medicinal treatments, collectively called "ART" (antiretroviral therapy) which control HIV infection by suppressing the virus in the bloodstream. ART is needed for life, and if a person stops taking ART the HIV infection returns in the bloodstream. So, there is good treatment, but no cure. The researchers want to test whether a period of treatment with vedolizumab can be used to control HIV infection in the bloodstream in persons with HIV on ART, after stopping ART. Objective: To determine whether vedolizumab is safe and tolerable in people with HIV, to assess the safety of an analytical treatment interruption (ATI), and to determine whether vedolizumab can control HIV infection in the bloodstream without the use of ART. Eligibility: Adults 18-65 with HIV who are being treated with ART Design: Participants will be screened with: Physical exam, medical history, blood and urine tests Participants will have a baseline visit which will include repeat of the screening testing. Participants will then present for their first study visit which will include: receiving vedolizumab infusions through an arm vein, repeats of the baseline testing. Participants will then have serial visits on a pre-specific schedule to receive ongoing vedolizumab doses every 2-4 weeks until week 20. Each visit will also include repeat of the baseline tests. After week 6 and before week 7 patients will discontinue ART. After the final infusion of vedolizumab at week 20 patients will continue to be assessed with physical exam, medical history, and repeat of the baseline testing every 4 weeks up to 1 year. ART will be re-started for participants if the level of HIV in the blood becomes too high, persists for too long, or if the CD4 count decreases by too much.
