View clinical trials related to Rabies.
Filter by:Rabies is a viral infectious disease of mammals including humans. Early symptoms of rabies include fever and tingling at the site of exposure, followed by one or more symptoms such as fear of water, violent movements, confusion, uncontrolled excitement, inability to move parts of the body, and loss of consciousness. Once symptoms of the disease develop, rabies is invariably fatal. It is one of the oldest human diseases. It continues to be a major public health problem in developing countries. Rabies is the 10th biggest cause of death due to infectious diseases worldwide. Rabies is endemic in Bangladesh with high public health significance and ranked third highest among rabies-endemic countries for human rabies deaths. In Bangladesh, an estimated 200 000 animal bite cases with more than 2000 human rabies deaths are reported annually. Most importantly, most of the victims are children below 15 years old coming from poor rural communities. Rabies is a vaccine-preventable viral disease and is highly effective when given pre- or post-exposure to a bite from a potentially rabid animal. Currently there is no locally manufactured Rabies vaccine available in Bangladesh. The results of this study will provide information regarding the immunogenicity and safety of the locally manufactured Rabies vaccine 'Rabix VC' as a test vaccine using 'Rabipur' as a comparator vaccine in a non inferiority study design.
This is a Phase 3, blinded, randomized study of SYN023 compared to a China licensed Human Rabies Immunoglobulin (a Rabies immune globulin from human sources, HRIG) for the prevention of rabies as part of post-exposure prophylaxis (PEP). The trial will enroll the World Health Organization (WHO) Category III rabies exposure subjects. The subject's death and rabies data will be reviewed by Data and safety monitoring board (DSMB) to confirm the safety. Besides, rabies vaccine would be administered after Study Drug in each group. This trial is proposed to further the licensure of SYN023 to provide an effective PEP alternative available to those exposed persons who need such a product. A placebo-controlled rabies trial is unethical thus HRIG is selected as the control group. Rabies immune globulin from equine and human sources (HRIG) have been evaluated in many trials and HRIG is the standard of care in China.
Primary Objective: To describe the immune response induced by VRVg-2 and Verorab vaccines at D14 and D35 when co-administered with Human Rabies Immunoglobulins (HRIG) at D0, according to the Zagreb (2-1-1) IM regimen in healthy adult subjects. Secondary Objective: Immunogenicity To describe the immune response induced by VRVg-2 and Verorab vaccines at D90 when co-administered with HRIG at D0, according to the Zagreb (2-1-1) IM regimen in healthy adult subjects. Safety To describe the safety profile of VRVg-2 and Verorab vaccines when co administered with HRIG at D0, after each vaccination.
The Phase I bridging clinical trial is to evaluate on the safety, pharmacokinetics (PK), pharmacodynamics (PD) and ADA of a single intramuscular injection of recombinant anti-rabies human monoclonal antibody injection (SYN023) alone or combined with rabies vaccine in healthy subjects. The study primary purpose was to compare the pharmacokinetics (PK) between U.S and China subjects, therefore to lay a foundation for the follow-up clinical trials. The secondary purpose was to evaluate the PK, PD, Safety and ADA of SYN023 in Chinese Healthy subjects and compare with that of U.S. subjects.
Primary Objective: To describe the immune response induced by VRVg-2 and Verorab vaccine at Day 14 (to assess the immune response after 3 doses [2-2-2]) and Day 42 (to assess the immune response after 4 doses [2-2-2-0-2]) when administered as standalone in healthy pediatric population or co-administered with HRIG (Group 5 and Group 6) at Day 0 in healthy adults. Secondary Objectives: - To describe the immune response induced by VRVg-2 and Verorab vaccine at Day 14 (to assess the immune response after 3 doses [2-2-2]) when co-administered with ERIG (Group 3 and Group 4) at Day 0 in healthy adults - To describe the immune response induced by VRVg-2 and Verorab vaccine at D90 (to assess the immune response 90 days post-rabies simulated exposure) when administered as standalone in healthy pediatric population or co-administered with HRIG (Group 5 and Group 6) at Day 0 in healthy adults - To describe the safety profile of VRVg-2 and Verorab vaccine as standalone in pediatric population or when co-administered with ERIG (Group 3 and Group 4) or HRIG (Group 5 and Group 6) at Day 0 in adults, after each vaccination.
This is a Phase Ib/II, open-label, head-to-head, age de-escalation dose-escalation, partially randomized trial to study the safety and immunogenicity of the candidate rabies vaccine ChAdOx2 RabG in healthy adults (age 18-45 years) and young children (age 2-6 years). ChAdOx2 RabG will be administered intramuscularly and licensed rabies vaccine will be given by intradermal injection.
x-ray has been proven to kill Rabies virus in vitro, so the investigators can use it in treatment of rabies infected patients.
This quasi-experimental, quality improvement study will be conducted across the Houston Methodist system, including all hospital-based and freestanding emergency departments (ED). Previous research identified opportunities to improve patient selection and delivery of rabies immune globulin (IG) as recommended by Centers for Disease Control and Prevention (CDC) guideline recommendations for rabies postexposure prophylaxis (PEP). The purpose of this study is to develop, implement, and measure the impact of a quality improvement bundle that consists of (1) rabies PEP electronic health records (EHR) enhancements, (2) education to ED staff, and (3) education to patients. Adherence to quality indicators, which are based on CDC guideline recommendations, for patient selection and delivery of rabies IG for 12 months following implementation (post-implementation group) will be compared with a historical control group.
This is a first-in-human, open-label, dose escalation, phase I clinical trial to assess the safety and immunogenicity of the candidate ChAdOx2 RabG vaccine in healthy UK volunteers aged 18-65. The vaccine will be administered intramuscularly (IM).
The primary objective of this study is: To demonstrate the Purified Vero Rabies Vaccine - Serum Free (VRVg-2) is non-inferior to Verorab and Imovax Rabies vaccines in each age group (pediatric and adult populations) when administered as a 3-dose pre-exposure prophylaxis (PrEP) regimen, in terms of proportion of participants achieving a rabies virus neutralizing antibody (RVNA) titer greater than or equal to (>=) 0.5 IU/mL at Day (D) 42, i.e., 14 days after the 3rd injection (for Primary Series Cohort 1). The secondary objectives of this study are: First 1-5 with hypotheses testing will be evaluated sequentially - only if the previous objective is achieved, will the next objective be tested. To demonstrate that: - the observed proportion of participants in the VRVg-2 (VRVg) group at D42 is at least 99% with a lower limit of the 95% confidence interval (CI) of at least 97% - VRVg is non-inferior (NI) to Verorab and Imovax Rabies vaccines (Imovax) in each age group at D28 - 2-dose VRVg at D28 is NI to 3-dose Imovax at D42 in each age group - the observed proportion of participants in the VRVg group at D28 is at least 99% with a lower limit of the 95% CI of at least 97% - 2-dose Imovax at D28 is NI to 3-dose Imovax at D42 in overall participants (Cohort 1) To describe: - the immune response induced by VRVg versus Verorab and Imovax at D28 and at D42 in all age groups - the immune response induced by VRVg at D14 after a booster dose of VRVg administered at Month (M) 12 (Cohort 1) and between M24 up to M36 (Cohort 2) - the persistence of immune response at M6,12,18, and pre-booster between M24 up to M36 post-primary series vaccination (Cohort 2) - safety profile of VRVg versus Verorab and Imovax in primary series and after a booster dose of VRVg.
