Safety Arm (1A):
Safety Arm is a phase 1A First-in-Human, Time Lagged, Single Ascending Dose Study of TY014 in Healthy Adult Volunteers.
Safety, tolerability and PK of TY014 will be assessed. The dose escalation will include 27 healthy volunteers in five (5) dose cohorts:
- 0.5 mg/kg, N = 2 TY014 +
Dengue fever is a major cause of illness and death worldwide. The disease is caused by dengue virus (DENGV) which gets transmitted to humans by the bites of infected Aedes mosquitoes. The dengue virus is a flavivirus genus as for example the West Nile virus, yellow fever virus or Zika virus. In
- Selection and enrolment of participants: Enrolment of patients will commence after completion of Wolbachia releases in the early zones. Study processes for enrolling patients presenting with febrile illness will be established at a network of primary health care facilities that serve the
Mosquito-borne viruses continue to cause significant global morbidity and mortality, particularly in Southeast Asia. When mosquitoes deliver the virus into the skin of humans while probing for a blood meal, they deposit also saliva, which contains a myriad of pharmacologically active compounds that
Protection provided by this product will be measured using entomological and virological approaches, comparing entomological indices will be measured through standard household monitoring of Aedes aegypti population densities, while DCZV transmission will be measured through door-to-door
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
The mais goal of the study is to assess the natural history of vertical ZIKV transmission from pregnancy to the end of third year of life and the existence of risk factors associated with the incidence of clinical and neurological disorders, specially microcephaly.
A longitudinal study will be
The aim of this proposal is to evaluate the causal relationship between Zika virus (ZIKV) infections in pregnancy and congenital malformations. We will estimate the absolute and relative risks of congenital malformations and other adverse outcomes of pregnancy among women who become infected with
Little is known about Zika virus (ZIKV) biology and its pathogenesis in humans. ZIKV has been detected in blood, urine, semen, cerebral spinal fluid, saliva, amniotic fluid, and breast milk. In most ZIKV infected individuals, the virus is detected in the blood from a several days to one week after
Despite successful control of many infectious diseases since the 19th century, viral diseases remain an important and significant health burden in the 21st century. In fact, the turn of the 21st century saw the emergence of not only new but also re-emergent pathogens such as SARS, MERS, West Nile,
Primary objective:
To assess the efficacy of community-based deployments of Wolbachia-infected Aedes aegypti mosquitoes in reducing the incidence of symptomatic, virologically-confirmed dengue cases of any severity in Yogyakarta residents aged 3-45 years in release areas, relative to non-release
Mosquito-borne diseases continue to cause significant morbidity and mortality worldwide despite on-going control efforts. In 2015, there were >200 million cases of malaria worldwide, causing nearly half a million deaths, with most of the deaths occurring among children under the age of 5 years.
The FilmArray Global Fever (GF) Panel, developed by BioFire Defense in collaboration with the U.S. Department of Defense and NIAID, uses an automated, multiplex PCR system to evaluate whole blood samples for 19 pathogens simultaneously in under an hour. Targets of the GF Panel are Chikungunya virus,
