Filter by:This is part of a feasibility study to compare the predicate standard FDA cleared test for serum to a point of care test Toxoplasma ICT IgG-IgM BK produced by LD Bio Diagnostic. The specificity and sensitivity in testing serum and whole blood will be compared. This study includes 70 persons either pregnant or non pregnant. This is being done in accordance with FDA requirements for clearance of a testing device . The investigators will use a standard FDA cleared test in all studies. The FDA has suggested that the investigators submit a pre subQ for a 510K and dual CLIA waiver. This allows the investigators also to determine feasibility of use of the predicate test in conjunction with the experimental test with volunteers, including men, women, and pregnant women.
This study aim is to assess impact of COVID-19 infection during pregnancy on outcome of pregnancy, and on developement of the child in early life.
Safety, immunogenicity and efficacy of GSK S. aureus candidate vaccine (GSK3878858A) when administered to healthy adults (dose-escalation) and to adults 18 to 64 years of age with a recent S. aureus skin and soft tissue infection (SSTI). In the dose-escalation safety lead-in phase in healthy adults safety and immunogenicity of 4 different compositions is assessed. After safety has been shown in this phase, in the second phase, proof of principle (PoP) phase of the study in adults with a recent SSTI safety, immunogenicity and efficacy of the final composition of the vaccine is assessed.
This is a Phase 3, double-blinded, randomised placebo-controlled, multi-centred trial evaluating the efficacy of the four-component meningococcal B vaccine, 4CMenB (Bexsero®), in the prevention of Neisseria gonorrhoeae infection.The targeted population is 18-50 years-old men (cis and trans), trans women and non-binary people who have sex with men (hereafter referred to as Gay Bisexual Men+ [GBM+], either HIV-negative and taking pre-exposure prophylaxis [PrEP], or HIV-positive with undetectable viral load <200copies/ml and a cluster of differentiation 4 [CD4] count >350 cells/cmm) who have high N. gonorrhoeae incidence and are recommended by Australian guidelines to have regular, comprehensive sexual health screening. 730 participants will be enrolled and randomised 1:1 and stratified by clinical sites to receive two doses of 4CMenB vaccine or a matching placebo at 0 and 3 months by intramuscular injection. Recruitment is for 12 months and all participants will be follow-up 3-monthly for a period of 2 years. The trial aims to evaluate the efficacy of 4CMenB in the prevention of N. gonorrhoeae infection.
We will study genetic factors causing severe disease due to infection with SARS-COV-2 which may help to find targeted therapy
This trial has two parts. Part A and Part B. Due to changes in the overall clinical development plan, Part B will no longer be conducted. The objectives originally described for Part B have been implemented in the ongoing development via a pivotal Phase I/II/III trial BNT162-02/C4591001 (ClinicalTrials.gov NCT: 04368728). Part A is for dose ranging of four different vaccines (BNT162a1, BNT162b1, BNT162b2, and BNT162c2) which will be undertaken with dose escalation and de-escalation plus the evaluation of interim dose levels. It also includes dose ranging in older participants. The vaccines BNT162a1, BNT162b1, BNT162b2, and BNT162c2 will be administered using a Prime/Boost (P/B) regimen. The vaccine BNT162c2 will also be administered using a Single dose (SD) regimen. Three additional cohorts aged from 18 to 85 years receiving BNT162b2 only. BNT162b2 has entered a Phase II/III evaluation of efficacy, with the intent to support an application for marketing authorization. The dosing regimen under investigation is two BNT162b2 doses given ~21 d apart.
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
The primary purpose of this phase I/II study is to evaluate whether partially matched, ≥2/6 HLA-matched, viral specific T cells have efficacy against adenovirus and CMV in subjects who have previously received any type of allogeneic HCT or solid organ transplant (SOT), or have compromised immunity. Reconstitution of anti-viral immunity by donor-derived cytotoxic T lymphocytes has shown promise in preventing and treating infections with adenovirus and CMV. However, the weeks taken to prepare patient-specific products, and cost associated with products that may not be used limits their value. In this trial, we will evaluate viral specific T cells generated by gamma capture technology. Eligible patients will include HCT and/or SOT recipients, and/or patients with compromised immunity who have adenovirus or CMV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.
This is an observational study, meaning that no interventions is tested, to determine incidence of SARS-CoV-2 infection and COVID-19 in different clinical sites in Brazil in several age groups. The study aims to assess baseline number of infected participants and perform a follow-up along two years to determine the new cases occurring among participants during the period. All participants will collect blood samples to get more details on the immune response.
The trial is designed as a phase III, double-blind, multicenter, randomized, single administration, active-controlled, parallel-group design with two groups of newborn infants receiving either VPM1002 or BCG SII (1:1 allocation) to assess the efficacy, safety and immunogenicity of VPM1002 against Mtb infection.
