Zika virus (ZIKV) is an illness people can get from mosquitoes. The infection is generally mild with symptoms that include a fever, rash, red eyes, and joint pain, though most of those infected have no symptoms. Preventing ZIKV is important because if a pregnant person is infected with ZIKV, it can cause birth defects in their unborn child. The goals of this study are to find out if people who have already been infected with one type of ZIKV can get infected with ZIKV a second time, and to test the ability of the TV003 dengue vaccine to prevent people from getting infected with the ZIKV-SJRP challenge virus.

The Zika epidemic has spread into the three French Overseas Departments in the Caribbean (DFAs). It is therefore urgent to set up tools to collect clinical and paraclinical data for the evaluation of potential complications due to having ZIKV infection during pregnancy. This study is meant to collect, within usual care practices, clinical and paraclinical information (including imaging and laboratory results) as well as biological samples allowing the precise description of the consequences of ZIKV infection during pregnancy. This study is the 2nd arm of a global research program in the 3 French Overseas Departments in the Caribbean. It is complementary to the first arm (ZIKA-DFA-FE) consisting in the follow-up of women in the French Overseas Departments who are pregnant during the Zika epidemic period. The study population is made up of infants born during and up to 9 months after the end of the Zika epidemic period in the French Overseas Departments. The data and biological specimens collected for this project will be done so through the recommended standard of care which has been put in place considering the ZIKV epidemic in the 3 French Overseas Departments, upholding existing recommendations (profession and/or recommendation from the public health authorities)
NCT04064905
This clinical study will evaluate the safety, tolerability and reactogenicity of mRNA-1893 Zika vaccines in flavivirus seronegative and flavivirus seropositive participants
NCT03624946
Currently, there are no licensed therapeutics against Zika virus infection. Due to this unmet medical need, Zika Virus Immune Globulin (ZIKV-IG) is being developed as a therapeutic intervention against Zika virus infection. In this first-in-human study, evaluation of ZIKV-IG safety and pharmacokinetics (absorption, metabolism and excretion) will be conducted in healthy adult volunteers.
NCT03110770
This was a multicenter, randomized study to evaluate the safety, immunogenicity, and efficacy of VRC-ZKADNA090-00-VP (Zika virus wildtype DNA vaccine) or placebo. In Part A, the primary objective was to evaluate the safety and tolerability of the vaccine in different vaccination regimens. In Part B, the primary objectives were to evaluate the safety and efficacy of the vaccine compared to placebo.
NCT03393286
The aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. The study will estimate the absolute and relative risks of congenital malformations and other adverse outcomes of pregnancy among women who become infected with ZIKV during pregnancy compared to uninfected pregnant women, also leading to further validation of the Congenital Zika Syndrome.
NCT03330600
Microcephaly associated with Congenital Syndrome of the Zika virus (SCVZ) was highlighted due to atypical structural and behavioral changes of the central nervous system. Such changes contribute to the appearance of functional impairments and difficulties of adaptation of the child to the necessary therapeutic follow-up. In this context, the search for adjuvant therapies that allow better management of these alterations has grown and, given its advantages, aquatic physiotherapy may be an auxiliary resource in the care of this population. The aquatic environment is capable of promoting a state of relaxation that, when associated with a kinesiotherapy protocol, is believed to have this potentiated effect. Thus, our objective will be to evaluate the efficacy of aquatic physiotherapy on the level of stress and muscle tone in children with microcephaly associated with SCVZ. A crossover, randomized, controlled and blind study will be carried out with children between 3 and 24 months of age, who will undergo two interventions: aquatic physiotherapy and water immersion. The evaluation of muscle tone will be performed through the Tardieu scale before and after the intervention; the physiological parameters (heart and respiratory rate, oxygen saturation and temperature) and the stress level will be evaluated before, immediately after and 30 minutes after the intervention. In addition, questionnaires will assess the child's behavioral state, level of irritation and sleep characteristics. For data normalization the Shapiro Wilk Test will be applied; the percentage values and relative frequency will be used for the descriptive analysis and for the numerical variables the values of mean and standard deviation or median and interquartile range. The paired T and ANOVA tests for repeated samples will be applied, which will analyze the intra-group time factor for the dependent variables of each individual. And for intergroup analysis, the variables may be submitted to the T-Test for independent or Mann-Whitney samples.
NCT03443830
Zika virus (ZIKV) infection is a new emerging arbovirus disease, caused by the same vector that transmits Dengue virus, Aedes aegypti. ZIKV is a growing public health problem, rapidly spreading throughout the continents since the first epidemic was reported in the French Polynesian islands. Currently, there are several ZIKV vaccine candidates in clinical trials. However, no ZIKV therapy (biologic or small molecule) has advanced to clinical trials. Tyzivumab will be the first therapeutic in the world, specifically targeting ZIKV, to enter clinical trials. This is a Phase 1, first in human, time-lagged, parallel-group, single dose ascending (6 dose cohorts), Tyzivumab, ZIKV monoclonal antibody (mAb), study to be conducted in 24 flaviviral naïve healthy adult volunteers. Tyzivumab will be administered once through single IV infusion over 30 minutes. Total duration of study participation is estimated at approximately 98 days from the date of screening. Post-trial monitoring through weekly telephone calls will continue from Day 85 post-dose onwards for another three (3) more months. The main objective of this study is to evaluate safety of Tyzivumab in healthy adult volunteers through assessment of subject vital signs, clinical laboratory results, ECG, presence/absence of AE/SAE, PK and ADA.
NCT03229421
The purpose of this study is to determine whether any diagnostic patterns exist in the symptom presentation of Zika Virus.
NCT03679728
Introduction: It is estimated that more than one million Brazilians were infected by zika virus in the last two years. Brazilian researchers first noted the virus's potential association with microcephaly. Objective: This study aimed to describe the motor performance of children aged between 6-18 months with the diagnoses of congenital Zika syndrome. Method: This is a cross-sectional, prospective and descriptive study. The study population consisted of 31 children. Participants were evaluated using Alberta Infant Motor Scale (AIMS) and Gross Motor Function Measure (GMFM).
