Filter by:The proposed study, 200207 is a double blind, placebo controlled, single and repeat dose escalation study to investigate the safety, tolerability and PK of GSK2838232 alone and when co-administered with RTV 100 milligram (mg) Once daily (QD). This study will enable future clinical development of GSK2838232 in healthy subjects and in a Phase IIa proof of concept study in Human Immunodeficiency Virus (HIV) infected patients. This study is a single and repeat dose escalation study and will be conducted as two Parts. Part A will evaluate GSK2838232 20 mg and 50 mg administered QD for 8 days and Part B will evaluate GSK2838232 10 mg, 20 mg, and 50 mg, co-administered with RTV 100 mg, QD for 11 days. The extended period of dosing is to account for the longer terminal phase half-life of GSK2838232 when given with RTV. Dose cohorts will be enrolled sequentially; enrollment into a cohort will commence following review of interim PK and safety data from at least 4 subjects in the preceding cohort. Subjects in both parts will have a screening visit within 30 days prior to first dose and a follow-up visit 7-14 days after the last dose. Maximum duration of study participation will be approximately 7 weeks. Approximately 40 healthy subjects will be enrolled, 8 subjects/cohort. Subjects will be randomized 3:1 to receive GSK2838232 or placebo.
This study investigates the safety, tolerability and PKs of GSK2838232 with and without Ritonavir, and to evaluate different formulations of GSK2838232 in healthy subjects. This study will evaluate higher single and RTV boosted doses to support continued clinical development of GSK2838232 at clinically relevant doses, and subsequently in those infected with HIV in a dose ranging phase 2 study. The study is conducted in 2 parts: Part A and Part B, study Part A and Part B may be conducted in parallel. Approximately 20 healthy subjects will be enrolled into the study, 8 in Part A and 12 in Part B. Part A is a double-blind, randomized, placebo-controlled, 4-period, single dose escalation design. Subjects will be randomized 3:1 to receive GSK2838232 or placebo. Subjects randomized to placebo will receive placebo in all four periods. Following completion of Period 2 PK assessments at 96hr post-dose, subjects will begin daily dosing of RTV 100mg for a total of 26 days. Part B is a randomized, open-label, unbalanced, 3-period, cross-over design; subjects will be randomized 1:1 to each sequence. The relative bioavailability of single 100mg doses of powder in a bottle (PIB) active pharmaceutical ingredient (API) of GSK2838232 versus PIB spray-dried dispersion (SDD) will be assessed. A single dose of GSK2838232 will co-administered on the 10th day of RTV dosing; RTV dosing will continue for an additional 4 days (total of 14 days). Subjects will have a screening visit within 30 days prior to first dose and a follow-up visit 7-14 days after the last dose.
This is a double-blinded, randomized controlled trial of 200 HIV-infected pregnant women living in Tororo, Uganda, an area of high malaria transmission. HIV-infected pregnant women between 12 and 28 weeks gestation will be randomized to receive enhanced malaria chemoprevention with monthly dihydroartemisinin-piperaquine (DP) versus monthly DP placebo. Their HIV-exposed children will receive the same prevention regimen from 2 to 24 months of age to which the mothers were randomized. All women will receive daily trimethoprim-sulfamethoxazole (TS) throughout the study per Uganda Ministry of Health guidelines. Children will also receive daily TS from 6 weeks to 24 months of age. TS will be considered a study drug only in infants and children beginning 6 weeks after cessation of breastfeeding and upon exclusion of HIV infection. Women and their children will be followed for 36 months after delivery. In a subset of the study population, the investigators will conduct an intensive pharmacokinetic study that will evaluate pharmacokinetic exposure of DP and EFV. The investigators will also measure HIV-related outcomes among the women enrolled in the study. The investigators will test the hypothesis that for HIV-infected mothers and HIV-exposed infants, that enhanced versus standard malaria chemoprevention in HIV-infected pregnant women and their children will reduce the incidence of malaria among children from 0 to 24 months of age and improve the development of naturally acquired antimalarial immunity.
This is a Phase II trial to determine the ability of a reduced intensity conditioning regimen to allow successful engraftment with CD3+ /CD19+ depleted peripheral stem cell grafts from mismatched donors. There are two conditioning regimens depending upon patient diagnosis and age.
This is an open-label, single sequence, 2-cohort, drug-drug interaction study in healthy male and female subjects. There is no formal hypothesis, however, it is expected that the coadministration of BMS-663068 with darunavir (DRV)/cobicistat (COBI) or COBI will increase the systemic exposure of BMS-626529.
The primary purpose is to provide access for patients who have immunodeficiency or severe autoimmune disease related to poor thymic function to cultured thymus tissue for implantation. With no thymus function, bone marrow stem cells do not develop into educated T cells, which fight infection. Eligible participants receive cultured thymus tissue for implantation and may undergo biopsy. Immune suppression may be given depending on the immune status and clinical condition of the participant. Immune function testing is continued for one year post-implantation.
The purpose of this study is to assess the impact of a light meal, a standard meal, and a high fat meal on the PK of BMS-955176 MC tablet at a dose of 180 mg, relative to fasted conditions.
The purpose of this study is to demonstrate non-inferiority in efficacy while switching to a once-daily single-tablet regimen containing darunavir (DRV)/ cobicistat (COBI)/ emtricitabine (FTC)/ tenofovir alafenamide (TAF) (D/C/F/TAF tablet) relative to continuing the current regimen consisting of a boosted protease inhibitor (bPI) combined with tenofovir disoproxil fumarate (FTC/TDF) in virologically-suppressed (human immunodeficiency virus type 1 ribonucleic acid [HIV-1 RNA] concentrations less than [<] 50 copies per milliliter [copies/mL]) HIV-1 infected participants.
Phase 3 multicenter, open-label study of safety, tolerability, efficacy, and pharmacokinetics (PK) of ProMetic's Immune Globulin Intravenous (Human) 10%, the investigational medicinal product [IMP]), in Adults and Children with Primary Immunodeficiency Diseases (PIDD).
Influenza ('flu) can cause severe infections, especially in people with weakened immune systems such as those with HIV. For this reason, yearly vaccination is recommended with the standard 'inactivated' influenza vaccine to try and prevent infections in these populations. It is also recommended in all health care workers, to help prevent the spread of influenza within healthcare settings. However, having HIV infection may mean vaccines work less well in some people and the investigators do not completely understand why. An alternative to the standard 'inactivated' annual influenza vaccine is the 'live attenuated influenza vaccine' (LAIV), which means it consists of weakened versions of the influenza virus. Unlike the standard vaccine, which is given by injection, LAIV is a spray that is given into each nostril. It is now given to children in the UK in preference to the standard vaccine as it results in greater protection from influenza. In some other countries, like the USA, adults are also given LAIV, where it seems to work just as well as the standard vaccine. A few studies in the past have shown that LAIV is safe and effective in HIVinfected children and adults. The investigators want to give LAIV to HIVinfected and HIV negative individuals, to try to find out new information about how HIV infection may change the way in which people respond to vaccines. The investigators will do this by comparing both the early genetic response to the vaccines and later responses from cells specifically targeted to fight influenza ('Tcells'), in these groups. In the long term, the investigators hope that this will lead to designing new ways of improving the response to vaccines in HIVinfected people. As LAIV is given into each nostril, rather than an injection, the investigators also want to see if LAIV results in Tcells in the lung that are specifically targeted to fight influenza
