Filter by:An open label, dose escalation, and dose expansion study to evaluate the safety, reactogenicity and immunogenicity of two SARS-CoV-2 DNA plasmid vaccine candidates, VB10.2129 (C1) and VB10.2210 (C2). tThree dose levels will be tested. IM administrations 21 days apart. Part 1 is a dose escalation phase and Part 2 is a dose expansion phase. In Part 2 a selected dose will be tested further in additional healty volunteers.
This is an open label study to evaluate the safety and immune response to a booster dose of Ad26.ZEBOV Ebola vaccine in HIV+ adults from Kenya and Uganda. Only participants who have received the 2-dose Ebola vaccine regimen "Ad26.ZEBOV/MVA-BN-Filo " in the VAC52150EBL2002 vaccine trial about 4 years ago are eligible to take part. Approximately 50 healthy HIV+ adults, aged 18 - 50 years at the time of the parent trial, will be invited. Participants will first be asked to provide consent to participate in this study. Upon receiving the booster vaccination, participants will be followed up for approximately 28 days (+/- 3 days) to collect information on side effects and provide blood samples for antibody measurement. This study is designed to provide descriptive information regarding vaccine safety and immunogenicity. There is no formal treatment comparisons and no formal testing of statistical hypothesis.
It is known that the pretreatment with exogenous interferon blocks SARS-CoV-2 infection, but intervention is much more effective if administered prior to infection. In this study the primary aim is to investigate 28-day regime of nasal interferon gama use in healthy participants for COVID-19 and other respiratory infections prevention.
The aim is to compare the percentage of the different SARS-CoV2 lineages that are detected in wastewater samples with matched clinical samples. About 1,400 swab samples from patients living in Nice were tested by Biogroup between Oct 19th and Oct 23rd (Week 43 of 2020). The sequence of 81 PCR positive samples, corresponding to all samples that were unambiguously assigned to one of the wastewater catchment areas and their lineage was determined. These values were compared to values measured in wastewater.
Given the magnitude of the epidemic in Puerto Rico, congenital Zika virus infection may have devastating complications to a significant population of children, also affecting families and society at large. This proposal takes a critical first step to ensuring that children with exposure to congenital Zika virus infection receive the follow-up care they need for optimal clinical outcomes. We anticipate that lessons learned from this study may also positively impact models for adherence to early intervention services in Puerto Rico.
Multi-center multinational-controlled study in Israel, Brazil, Spain, and South-Africa. 240 adult patients who suffer from moderate COVID-19 infection. Safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments and vital signs. After Screening visit, the study drug will be administrated twice a day morning and evening (every 12 hours) during (day 1 and day 2) The patients will be randomized in 1:1:1 ratio to study drug (CimetrA) in two dosages in addition to Standard of Care - Arm 1, 2 or (Placebo) in addition to Standard of Care- Arm 3.
The global COVID-19 pandemic has caused unprecedented strain on health care services around the world.The absence of specific anti-viral medications to treat the underlying infection led to a proliferation of clinical studies and trials aimed at re-purposing existing medications. Human dihydroorotate dehydrogenase (DHODH) is vital enzyme utilised by viruses to replicate in the host cell. Leflunomide, a drug that is already licenced to treat rheumatoid arthritis, is a potent inhibitor of the enzyme DHODH. Importantly, this drug has dual anti-viral and anti-inflammatory properties so it targets viral replication and suppresses host inflammatory response which plays a role at more progressive stages of infection. DEFEAT-COVID is a multi-site, international, interventional, pragmatic, parallel group design, open label, randomised CTIMP with a pilot phase that will allow to adapt procedures and assessments if required. A phase III clinical trial of leflunomide for treating COVID-19 has been registered in China, Registration number: ChiCTR2000030058). The current proposal extends the original clinical study of leflunomide in China (People's Hospital of Wuhan University) to the UK through a structured collaboration.
It is a single-center, randomized, open-label, phase IV study for the explorative investigation of the pharmacological mode-of-action of Echinaforce® extract in the form of Echinaforce® Chewable tablets"- Further, it is aimed to evaluate the effectiveness of the study product for the prevention and treatment of respiratory tract infections in generally healthy adults following a real-life setting. The study covers 2x2 + 1 month of prevention in 120 randomized participants following a tight sampling set-up for sensitive detection of viral infections by RT-qPCR analysis of nasal swabs and seroconversion of SARS-CoV2 IgG/IgM in serum samples.
This is a two-arm, randomized, open label, monocenter, controlled study to evaluate the safety and efficacy of Viusid plus Asbrip in patients with mild and moderate symptoms of respiratory illness caused by Coronavirus 2019 infection.
This is a A Phase III, Open label, Multicenter, Single Arm Study to assess the Safety, Tolerability and Immunogenicity of VLA2001 in volunteers aged ≥ 56 years. Approximately 300 participants are enrolled in a non-randomized manner.
