This is a prospective, multi-center, randomized, open-label, 2-period cross-over study (16 weeks per treatment period) to evaluate flexible dosing and daily push dosing of IGSC 20% in treatment-experienced subjects with PI. An additional, separate cohort of treatment-naïve, non-randomized subjects who will not be part of the crossover are included and will receive a loading dose of 5 consecutive daily doses of IGSC 20% followed by weekly infusions of IGSC 20% starting Week 1 (Day 8) through Week 32 (end of Treatment Phase). For treatment-experienced subjects, the study consists of a Screening Visit, Baseline Visit, 16-week Treatment Period 1, 16-week Treatment Period 2, and Final Visit/Early Termination Visit. For treatment-naïve subjects, the study consists of a Screening Visit, a Baseline Visit, a 32-week Treatment Phase, and Final Visit/Early Termination Visit. Approximately 54 treatment-experienced subjects and approximately 6 treatment-naïve subjects will be enrolled at study centers in the United States (US) and European Union (EU).
Background: HIV stands for human immunodeficiency virus, which is the virus that causes AIDS. There is currently no licensed vaccine to prevent HIV infection. Researchers want to test a vaccine called Trimer 4571 for the first time. It was made at the National Institutes of Health (NIH) and contains no HIV. The vaccine is mixed with a substance called alum and injected in the arm. Alum is included to boost the body's immune response to the vaccine. It has been used in licensed vaccines for over 60 years and has been found to be safe. Objectives: To see if the vaccine Trimer 4571 is safe, well-tolerated, and to study immune responses to it. Eligibility: Healthy adults ages 18-50 years Design: Participants were screened with a physical exam and blood tests. They agreed to not become pregnant and to avoid behavior that would put them at high-risk for HIV infection during the study. Participants had about 15 study visits over about 9 months. The first 6 participants received a low dose of the vaccine mixed with alum. Once the low dose was deemed safe, 10 new participants were allocated to receive a higher dose. All participants were randomly assigned to get the vaccine by injection in a muscle or under the skin. All participants received a total of 3 vaccine injections over 20 weeks. Each visit where participants received the vaccine lasted about 5 hours. Participants were watched after each injection. Participants who were able to get pregnant would have a pregnancy test before each injection. Participants received a thermometer and recorded their temperature and symptoms every day for 1 week after each injection. The injection site was checked for redness, swelling, or bruising. At follow-up visits, participants had blood drawn and checked for health changes or problems. Follow up visits lasted about 1-2 hours.
HIV virus is an etiologic agent of ( AIDS ) immunodeficiency syndrome . It is known that the estimated rate of transfer from mother to baby is 25% to 45%, pregnancy rate is 5-10%, pregnancy rate is 15-20% and in lactation period is 5-10%. Risk factors; maternal viral load, breastfeeding, vaginal birth, and prematurity. Although there is a high rate of false positivity in prenatal screening in our country, one of the factors affecting this is the number of pregnancies.
Observational study looking at barriers to care for individuals seeking care, Post Exposure Prophylaxis (PEP) after an actual or perceived exposure to HIV. Following PEP treatment subjects will be asked about there intent to transition to Pre-Exposure Prophylaxis (PrEP) and surveyed about barriers to care or perceptions of care
This is a prospective, non-randomized, single-cohort, longitudinal, single-center, clinical study designed to assess the efficacy and safety of a cryopreserved formulation of OTL-101 (autologous CD34+ hematopoietic stem/progenitor cells transduced ex vivo with EFS (Elongation Factor 1α Short form) Lentiviral Vector (LV) encoding for the human ADA gene) administered to ADA-SCID subjects between the ages of >/=30 days and <18 years of age, who are not eligible for an Human Leukocyte Antigen (HLA) matched sibling/family donor and meeting the inclusion/exclusion criteria. The OTL-101 product is infused after a minimal interval of at least 24 hours following the completion of reduced intensity conditioning. For subjects who successfully receive the OTL-101 product, pegademase bovine (PEG-ADA) Enzyme Replacement Therapy (ERT) is discontinued at Day+30 (-3/+15) after the transplant. After their discharge from hospital, the subjects will be seen at regular intervals to review their history, perform examinations and draw blood samples to assess immunity and safety.
While advances in medication have led to greatly improved outcomes for people living with HIV/AIDS, less than one-third of all people living with the disease are adherent enough to their medication to achieve viral suppression. Alcohol consumption has been shown to have a significant effect on HIV medication adherence, so the proposed research will aim to reduce alcohol use among people living with HIV/AIDS through a technology-driven intervention. This eight-session intervention will be delivered using a combination of videoconferencing, smart phones, and Bluetooth-enabled breathalyzers for monitoring of alcohol consumption, with an overall goal of reducing alcohol use, mitigating adherence issues, and achieving optimal prevention and treatment responses for people living with HIV/AIDS.
Patients with chronic lymphocytic leukemia (CLL) are at increased risk of infections as compared to age matched controls, with infections being a major cause of morbidity and mortality. Previous studies have shown that patients with CLL have both hypogammaglobinemia and impaired humoral immunity as defined by vaccine responses to both polysaccharide and peptide antigens. Attempts at decreasing infections in CLL have included therapy with prophylactic antibiotics and intravenous immunoglobulin. In general clinical practice and in previous studies, patients have started IV immunoglobulin replacement therapy if they have a history of serious infection or hypogammaglobinemia (defined as Immunoglobulin G below 500-600 g/dL), but vaccine responses have not been evaluated. This study will identify CLL patients with humoral immunodeficiency by checking both Ig levels and vaccines responses. In patients with impaired humoral immunity, the investigators will use subcutaneous immunoglobulin replacement to show this intervention will increase Ig levels, protective antibody titers, and be well tolerated.
