Active clinical trials for "Immunologic Deficiency Syndromes"

Vicriviroc (vye-kri-VYE-rock) is an investigational drug (not yet approved by Government Regulatory Authorities for commercial use) that belongs to a new class of drugs, called CCR5 receptor blockers. This group of drugs blocks one of the ways HIV enters T-cells (the cells that fight infection). Previous smaller studies in HIV treatment-experienced patients, have shown that vicriviroc is safe and effective. The purpose of this study is to investigate in subjects with detectable dual/mixed CCR5/CXCR4-tropic HIV whether vicriviroc when added to other appropriate HIV drugs can decrease the level of HIV (viral load) in the blood and that it is well tolerated. This is a randomized, double-blind, placebo-controlled, parallel-group, multi-center study of vicriviroc maleate in HIV subjects infected with dual/mixed CCR5/CXCR4-tropic virus and who have documented resistance to at least 2 of the 3 antiretroviral drug classes (NRTI, NNRTI or PI) or at least 6 months experience with at least 2 of the following: one NRTI, one NNRTI, or one PI (excluding low-dose ritonavir) and failure on their current stable regimen. The study will compare the virologic benefit of adding vicriviroc to an optimized background regimen to a control group receiving placebo plus the new optimized background therapy. The optimized background regimen will be chosen by the investigator based on results of drug susceptibility tests performed at Screening, history of prior antiretroviral drug use by the patient, and drug toxicity. Primary efficacy analysis will be conducted when all subjects have completed 48 weeks of treatment. An interim analysis will be performed when all subjects have completed 24 weeks of treatment. Subjects who complete 48 weeks of treatment, or who discontinue early but are deemed eligible upon rescreening, will be offered participation in the open-label segment of the study, and will receive vicriviroc 30 mg once daily, if appropriate, until commercially available or until the sponsor terminates the clinical development of vicriviroc.

This phase II trial studies fludarabine phosphate and total-body irradiation with or without alemtuzumab followed by donor stem cell transplant to see how well it works in treating patients with immunodeficiency or other nonmalignant inherited disorders. Giving chemotherapy, such as fludarabine phosphate, a monoclonal antibody such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of abnormal cells. It may also stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining abnormal cells.

Tuberculosis (TB) is the most common opportunistic infection among HIV infected persons living in developing countries. Directly observed treatment, short-course (DOTS) is the internationally recommended strategy for the treatment of TB. However, the efficacy of DOTS for the treatment of HIV-associated TB is not well studied. This study aims to compare the efficacy of thrice weekly DOTS in HIV-infected versus HIV-negative patients with TB.

This study will compare the effectiveness of enhanced counseling alone versus enhanced counseling combined with observed therapy at improving medication adherence in people with HIV.

This pilot study will provide data on the safety and efficacy of the combination of Raltegravir (RAL) 400mg BID + Atazanavir (ATV) 300 mg BID in Antiretroviral (ARV)-experienced subjects that have a suppressed HIV viral load on a Ritonavir (RTV) boosted Protease Inhibitor (PI) based regimen who are then switched to a regimen of RAL 400mg BID +ATV 300mg BID.

The study aims to assess the safety and tolerability of subcutaneous Ig NextGen 16% in patients with Primary Immune Deficiency who require Immunoglobulin (Ig) G replacement therapy. Ig NextGen 16% is a liquid immunoglobulin (antibody) preparation.

The purpose of this study is to evaluate the antiviral activity as measured by the change in viral load from baseline in the 14 days following initiation of treatment with 4 different dose regimens of TMC310911 co-administered with ritonavir.

The objectives of this trial are the assessment of safety and efficacy of IgPro10 in patients with PID, and the assessment of tolerability of high infusion rates. To demonstrate safety, the number of infusions temporally associated with AEs, the rate, severity and relationship of all AEs and the vital sign changes during each infusion will be evaluated.

The main objective of this study is to see if GAMMAPLEX is efficacious with respect to Food and Drug Administration (FDA) minimal requirements (no more than 1 serious, acute, bacterial infection per subject per year) in subjects with Primary Immunodeficiency Diseases (PID). The secondary objectives are to assess the safety and tolerability of GAMMAPLEX and to determine if GAMMAPLEX has a pharmacokinetic (PK) profile comparable with that of intact Immunoglobulin G (IgG) in subjects with PID.

The purpose of this study is to evaluate the effectiveness and safety of epoetin alfa in AIDS patients for the treatment of anemia that is a result of the disease and zidovudine (AZT) treatment. Epoetin alfa is a genetically engineered protein that stimulates red blood cell production.
