Active clinical trials for "Immunologic Deficiency Syndromes"

This study is a continuation of the study ZLB06_001CR with the objective of assessing efficacy, tolerability, safety of IgPro, as well as long-term health-related quality of life in patients with PID.

The purpose of this study is to evaluate the tolerability of IGIV, 10% given subcutaneously and the pharmacokinetics of immunoglobulin G (IgG) following subcutaneous (SC) treatment with IGIV, 10% in subjects with primary immunodeficiency (PID) disorders.

The purpose of this study is to determine if NABI-IGIV (10%) [Immune Globulin Intravenous (Human), 10%] is safe and effective in preventing serious bacterial infections (SBIs) in the treatment of patients with primary immune deficiency disorders (PIDD) when compared to historical control data.

The objective of this study is to assess the efficacy and safety of Vivaglobin in previously untreated patients (PUPs) with primary immunodeficiency (PID) over a 25-week observation period. The purpose is to investigate whether PUPs will respond to subcutaneous immunoglobulin (SCIG) treatment with adequate trough levels without first receiving immunoglobulins by the intravenous route by demonstrating that 100 mg immunoglobulin G/kg body weight (IgG/kg bw) administered on 5 consecutive days (i.e. resulting in a total dose of 500 mg IgG/kg bw) results in an IgG increase to ≥ 5 g/L on Day 12 after initiation of SCIG therapy.

This study investigated the safety and efficacy of different gene therapy approaches for Severe Combined Immunodeficiency (SCID) caused by the deficiency of adenosine deaminase (ADA) enzyme. This is a severe condition that can be cured by HLA-matched sibling donor bone marrow transplantation. Patients were enrolled if no HLA-identical sibling donor was available and the patient showed evidence of failure of enzyme replacement therapy or this treatment was not a long-term available option. The aim of the study was to evaluate the safety and efficacy of the procedure and to identify the relative role of peripheral blood lymphocytes and hematopoietic stem cells and progenitor cells in the long-term reconstitution of immune functions after retroviral vector mediated ADA gene transfer.

Raltegravir is the first integrase inhibitor used in humans. It has been shown to be highly efficacious and well tolerated in phase III clinical trials in multidrug experienced human immunodeficiency virus(HIV)-infected patients, as well as initial therapy in untreated patients. Pharmacokinetic studies in healthy adult subjects indicate that the major mechanism of clearance of the drug is glucuronidation mediated by UGT1A1, with a minor contribution of renal excretion of unchanged parent compound. Unlike CYP-based metabolism, glucuronidation is generally found to be relatively unaffected by hepatic disease. A single dose pharmacokinetic study of raltegravir in patients with mild to moderate hepatic insufficiency (Steigbigel et al. 2008) found no clinically important effect on the drug pharmacokinetic profile, with no dosage adjustment being necessary. The liver safety and tolerability of boosted atazanavir (ATV/r) has been evaluated in human immunodeficiency virus and hepatitis C virus (HIV/HCV) coinfected patients with advanced liver disease (decompensated cirrhosis) (Hermida JM et al. 4th IAS: Sidney, 2007). Similar to Raltegravir, ATV is also mainly metabolized by conjugation through UGT1A1. There is an urgent need for potent and efficacious ARV drugs with a clean safety liver profile even in patients with severe liver disease. The investigators hypothesized that pharmacokinetics will not be altered in HIV/HCV patients with advanced (Child-Pugh grade C) cirrhosis or in those with no histologic liver damage.

The purpose of this study is to evaluate the pharmacokinetics (what the body does to the medication), safety and antiviral activity to support dose recommendations by body weight of darunavir with low-dose ritonavir (DRV/rtv), in combination with other antiretroviral drugs (ARVs), in treatment-experienced Human immunodeficiency virus 1 (HIV 1) infected children.

The purpose of this study was to compare the safety, tolerability, and antiviral activity of once-daily (QD) and twice-daily (BID) dosing of the lopinavir/ritonavir (LPV/r) tablet formulation in combination with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) in antiretroviral-experienced human immunodeficiency virus type 1 infected subjects with detectable viral load while receiving their current antiretroviral therapy.

This study is a Phase 2/3, multicenter, double-blind, randomized, parallel-group, placebo-controlled, dose-finding trial of Serostim® (mammalian cell-derived recombinant human growth hormone, r-hGH) versus placebo in subjects with human immunodeficiency virus-associated adipose tissue redistribution syndrome (HARS). The primary study objective is to determine whether Serostim® treatment reduces adipose tissue maldistribution more effectively than placebo. The primary co-endpoints are derived from measures of visceral adipose tissue assessed by computerized tomography (CT) and the ratio of trunk; and limb fat assessed by dual-energy X-Ray absorptiometry (DXA) scans. Anthropometric measures, physical exams, quality of life assessments, serial photographs, and various laboratory measures will be used to address secondary objectives. These secondary objectives relate to the impact of Serostim® on Physician and subject assessments of change in body shape, health-related quality of life, attitude towards medication compliance, metabolic markers, fat redistribution, and safety. On Day 1, eligible subjects will be randomized in a 1:1:1 ratio to receive daily Serostim®, Serostim® and placebo given on alternate days, or daily placebo. Serostim® doses will be based on body weight, with a maximum dose of 4 milligram (mg). Therapy will continue for 12 weeks. Treatment will then be altered and the new treatment will be continued through Week 24. Interim Study Visits will be required at Weeks 2 and 4 (Treatment Period 1) and at Weeks 14 and 16 (Treatment Period 2). Subjects will be offered to be enrolled into a maintenance Protocol (Study 23056) at Week 24.

This study will determine whether an experimental medicine, STA-5326 mesylate, is safe to use in patients with common variable immunodeficiency (CVID) who have inflammation of the gut. It will also determine if patients who take this drug show improvement in their symptoms, decrease in inflammatory chemicals in the gut, changes in their immune cells, and improvement in how their gut is functioning to absorb food. Patients between 18 and 75 years of age with CVID and chronic diarrhea or involuntary weight loss of more than 5 percent of their past body weight over the past 12 months may be eligible for this study. Candidates are screened with a review of their medical records, a medical history and physical examination, blood, urine and stool tests, chest x-rays and skin test for exposure to tuberculosis, and a hydrogen breath test. For the latter, breath samples are collected before and every 20 minutes (for 2 hours) after the subject drinks a sugar solution. This test determines the digestive effects of bacteria in the upper intestine. Samples are collected by having the subject blow into a balloon. Participants undergo the following tests and procedures: Immune System and Gastrointestinal Evaluation 48-hour stool fat collection (measures the amount of undigested fat in the stool): Subjects keep a diary of what they eat for a 48-hour period. At the beginning of the 48 hours they take two dye capsules and then take another two capsules 48 hours later. They collect a stool sample when they pass the second set of capsules in their bowel movement. An additional 24-hour stool collection is tested for loss of protein in the stool. D-xylose absorption test (measures the ability of the gut to absorb nutrients): Subjects drink a solution of d-xylose (a sugar substitute). Blood samples are collected before and 1 hour after drinking the solution. Upper endoscopy: A thin flexible lighted tube is advanced through the mouth to evaluate the esophagus, stomach and beginning of the small intestine. Lower endoscopy: A thin flexible lighted tube is advanced through the rectum to evaluate the colon. Treatment Period (Study days 1 to 57) Physical examination - study days 1, 8, 15, 29, 43 and 57 Blood samples to test the levels of STA-5326 in the blood. On study days 1 and 57, samples are collected before the medication dose and 1, 2, 4, 6 and 8 hours after the dose; on day 29, one sample is collected before the medication dose.
