Filter by:In this open-label Phase 3b, single arm study, persistence of antibodies and long term safety will be evaluated in up to 375 subjects rolled over from study VLA1553-301 (NCT number: NCT04546724).
This was a prospective, randomized, double-blinded, multicenter Phase 3 clinical study investigating three Lots of VLA1553 at the final dose. Overall 409 healthy subjects aged 18 to 45 years were randomized into the study.
This is a prospective, randomized, double-blinded, multicenter, pivotal study evaluating the final dose of VLA1553 (1 x10E4 TCID50 per dose) in comparison to a placebo control. The final dose of VLA1553 or control will be administered as single immunization on Day 1. Overall, approximately 750 male and female subjects aged 12 years to <18 years will be enrolled into the study.
Chikungunya vaccine is an inactivated virus vaccine. There will be three study arms and subjects will be vaccinated in a dose escalation manner.In each arm, vaccine will be administered on Day 1, Day 29, and Day 57. Vaccine will be administered through intramuscular route.
This study has a Phase II with part A and part B and a Phase III with part C. This Adaptive seamless design will prospectively include planned modifications and incorporate both dose selection (parts A and B) and confirmation of the selected dose (part C) based on the accumulation of subjects' data within the entire study period as shown below. Part C will be randomized for immunogenicity subset and will be open label for safety cohort. The participants assigned to the control group from all parts (i.e, Part A, B and C) will be continuously followed up from the enrollment until the end of the study.
This was a prospective, randomized, double-blinded, multicenter, pivotal clinical study evaluating the final dose of VLA1553 (1 x10E4 TCID50 per dose) in comparison to a placebo control. The final dose of VLA1553 or control was administered as single immunization on Day 1. Overall, 4.128 male and female subjects aged 18 years and above were randomized into the study.
MARCH is the first randomized, double-blind, placebo-controlled evaluation of the efficacy and pathologic mechanism determined by synovial biopsy of 6 months of methotrexate (n=100) versus placebo (n=50) therapy for chronic chikungunya (CHIKV) arthritis in Colombia with the option for open-label use of the medication for up to one year for all participants. Our central hypothesis is that methotrexate will significantly decrease chronic CHIKV arthritis disease severity compared to placebo via suppression of leukocyte accumulation in synovial tissue and decreased expression of inflammatory cytokines from synovial macrophages and fibroblast-like synoviocytes (FLS).
The purpose of this study is to assess the benefits of a 8-week yoga program on quality of life in patients suffering from chronic chikungunya. Studies have already shown the effectiveness of yoga practice on various arthralgia's, on the reduction of inflammatory reactions, on psychological disorders/sleep disorders and on quality of life. Considering quality of life as a global experience of balance between physical and mental wellbeing, the hypothesis was that the practice of yoga would globally improve the quality of life of patients with chronic chikungunya.
A single, ascending-dose design with five dose-cohorts of 8 subjects. Forty healthy adults aged 18 to 45, inclusive, will be recruited and admitted at multiple sites. Each subject will be randomized to receive either SAR440894 or matching placebo via 60-minute intravenous infusion. In each cohort of 8 subjects, the randomization ratio will be 6 active to 2 placebo, and 2 sentinel subjects (one from each active and placebo group) will be dosed first. Dosing of the next dose-cohort will be dependent on acceptable meeting predefined safety criteria in the preceding cohort. Each subject's participation will take place over approximately 150 days, not including the screening visit. There are no hypotheses for this phase I study. The primary objective will be to determine the safety of single ascending intravenous (IV) infusions of SAR440894 when administered in healthy adults.
Phase Ib, single centre, double-blind, double-dummy placebo-controlled, randomised, stepwise dose escalated, vaccine trial to assess the safety and immunogenicity of the candidate ChAdOx1 Chik and ChAdOx1 Zika vaccines, given as a standalone vaccines or in co-administration. Healthy volunteers aged 18-50 years old, residents of the metropolitan area of Monterrey (Mexico), will be recruited as participants
