Active clinical trials for "Immunologic Deficiency Syndromes"

The primary objective of this study is to evaluate the efficacy of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (Genvoya®; E/C/F/TAF) fixed-dose combination (FDC) versus elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (Stribild®; E/C/F/TDF) FDC in HIV-1 infected, antiretroviral treatment-naive adults.

X-linked severe combined immunodeficiency (SCID-X1) is an inherited disorder that results in failure of development of the immune system in boys. This trial aims to treat SCID-X1 patients using gene therapy to replace the defective gene.

RATIONALE: Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x rays to kill tumor cells. Giving cisplatin together with radiation therapy may be an effective treatment for cervical cancer. PURPOSE: This trial studies how well cisplatin and radiation therapy work in treating participants with HIV-associated locally advanced cervical cancer.

Liver disease is one of the leading co-morbidities of human immunodeficiency virus (HIV) infection, and nonalcoholic fatty liver disease (NAFLD) is present in approximately 30-40% of patients with HIV infection. Nonalcoholic steatohepatitis (NASH) is a more severe form of NAFLD in which increased liver fat is also accompanied by inflammation, cellular damage, and fibrosis. NAFLD is most prevalent in patients who also have increased visceral adiposity, and our group has previously shown that HIV-infected individuals with increased visceral adiposity generally have decreased growth hormone secretion. Tesamorelin is a growth hormone releasing hormone (GHRH) analogue that increases endogenous growth hormone secretion. Tesamorelin is FDA-approved for the reduction of visceral fat in HIV-infected individuals. In a previous study, treatment with tesamorelin in HIV-infected individuals selected for abdominal adiposity reduced liver fat. The current study is designed to test the effect of tesamorelin on liver fat and steatohepatitis in HIV-infected individuals who have NAFLD. The investigators hypothesize that tesamorelin will reduce liver fat and will also ameliorate the inflammation, fibrosis, and hepatocellular damage seen in conjunction with NASH.

This is an open-label phase III study with a 12-week wash-in/wash-out period followed by a 12-month efficacy period. The main goals of the study are to assess the efficacy of octanorm in preventing serious bacterial infections (SBI) compared with historical control data and to evaluate the pharmacokinetic (PK) characteristics of octanorm.

The primary objectives of this study are to assess the safety of ABT-450/r/ABT-267 with and without ABT-333 coadministered with and without ribavirin (RBV) for 12 and 24 weeks in HCV GT1- or 4-infected participants with HIV-1 coinfection and to evaluate the percentage of subjects achieving HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment.

Despite increased HIV (Human Immunodeficiency Virus) infection testing in Africa, many patients never enroll in subsequent HIV care after testing or remain in care after an initial enrollment. This study's aim is to improve linkage to HIV care and retention in HIV care through the use of feasible, evidence-based, and practical interventions. The study takes place in Swaziland, the country with the highest HIV prevalence (24%) in sub-Saharan Africa. The study will randomize groups of HIV testing sites and affiliated clinics to either standard of care or a combined intervention strategy (CIS) which consists of point-of care CD4 (cluster differentiation 4 (CD4)) testing at time of HIV testing, fast-track HIV medications for those who are eligible for treatment,mobile phone appointment reminders, care bags filled with health prevention materials, and financial incentives. The study outcomes are linkage to and retention in care as well as cost effectiveness, feasibility of interventions, and patient acceptability of interventions.

OBJECTIVES: I. Evaluate the safety and efficacy of intravenous cidofovir in patients with small peripheral cytomegalovirus retinitis. II. Obtain safety and efficacy data related to different dosages of cidofovir.

Background: Stem cells are immature blood cells that grow in the bone marrow and produce all of the cells needed for normal blood and immunity. Stem cells can be taken from one person (donor) and given to another person (recipient) through allogeneic stem cell transplantation. Donor stem cells can then replace the recipients stem cells in the bone marrow, restoring normal blood production and immunity. Most allogeneic transplants now use stem cells collected from the donors blood in a process called peripheral blood stem cell transplantation. Monocytopenia and mycobacterial infection (MonoMAC) is an immunodeficiency disease that is characterized by a lack of monocytes, a type of white blood cell, and an increased risk of developing mycobacteria infections that may cause tuberculosis. Allogeneic stem cell transplantation has been used successfully to treat many kinds of immune diseases and cancers that develop in blood or immune system cells. Researchers have been studying a particular kind of stem cell transplantation that uses lower than usual doses of chemotherapy and particular combinations of drugs to improve the results of the procedure for patients with blood-related cancers and pre-cancerous conditions. Objectives: To determine the safety and efficacy of reduced-intensity hematopoietic stem cell transplants (a particular stem cell transplantation procedure) for treating MonoMAC. Eligibility: Patients 18-60 years of age who have MonoMAC and who have been matched with a suitable stem cell donor. Design: Donors and recipients will undergo separate procedures as part of this protocol. Donors: National Institutes of Health researchers will take the donor s medical history, perform a physical exam, take blood samples, and explain the procedure. Tests will be performed to check the donors heart, lung, kidney, and liver function. Donors will receive injections of a drug called filgrastim (G-CSF), which causes stem cells to travel from bone marrow into blood. The G-CSF shots will be given for 5 to 7 days before the collection procedure. Donors will undergo apheresis to collect white blood cells and stem cells directly from the blood, which can be done as an outpatient procedure. Researchers may consider the alternative of directly collecting bone marrow from the donor, which will require an overnight hospital stay. Recipients: Recipients will receive 3 days of pre-transplant chemotherapy and radiation therapy to prepare for the transplant. For 4 days before the transplant, recipients will receive the chemotherapy drug fludarabine, followed by a single dose of radiation therapy, and will also receive the drugs tacrolimus and sirolimus to prevent the donor cells from attacking the recipient s normal tissues. Recipients will then receive the transplant of donor stem cells and will continue to receive tacrolimus and sirolimus for 3 months after the transplant to prevent the donor cells from attacking the recipient s normal tissues. Recipients will be discharged from the hospital once their condition is stable. Recipients will visit the NCI clinic regularly for the first 5 months after the transplant, and then less often for at least 5 years. Recipients may receive additional donor immune cells (donor lymphocyte infusion) after the transplant if the study doctors believe they are needed.

The objective of this study is to assess the efficacy, tolerability, safety and pharmacokinetics of IgPro20 in patients with primary humoral immunodeficiency (PID).
