Filter by:The primary objectives of the study are to evaluate the safety, tolerability, and efficacy of voxilaprevir (VOX) plus sofosbuvir/velpatasvir (SOF/VEL) fixed dose combination (FDC) in adults with chronic non genotype 1 hepatitis C virus (HCV) infection.
This primary objectives of the study are to evaluate the safety, tolerability, and efficacy of voxilaprevir (VOX) plus sofosbuvir/velpatasvir (SOF/VEL) fixed dose combination (FDC) ± ribavirin (RBV) in adults with chronic genotype 1 hepatitis C virus (HCV) infection.
Ebola virus causes an infection known as Ebola virus disease (EVD). This it is generally a severe disease which can also lead to death. The 2014 outbreak of EVD in West Africa is the largest ever. Researchers want to develop a vaccine to prevent Ebola infection. This study will assess the safety of a single dose of the bivalent Ebola Zaire candidate vaccine VRC-EBOADC069-00-VP (cAD3-EBO) when administered to healthy Malian adult volunteers, age 18-65 years (mostly health care workers and other front line workers [e.g., individuals who incinerate contaminated materials]), at one of 2 dosage levels, 2.0 x 10(10) vp or 2 x 10(11) vp. It is impossible for someone to get an Ebola infection from this vaccine. Heterologous booster dose allocation - Each participant will be offered the opportunity to be included in the booster step of this study. After obtaining consent and the additional review of pertinent medical history, participants in each group will be randomized to receive the candidate booster vaccine, MVA-EbolaZ or placebo. This will be the first clinical trial in Mali with bivalent cAd3-based Ebola vaccine and the first where the dosage level contains > 10(11) vp. It follows completion of a Phase Ib trial in Malian health care workers that tested three dosage levels of monovalent cAd3-EBO Z vaccine. The data generated in West Africans (Mali) on the tolerability and immunogenicity of the bivalent vaccine will be compared to clinical and immunologic responses documented in in parallel studies in East African subjects (Uganda) and North American subjects (NIH, Bethesda, MD, USA). Objectives: - To see if an Ebola vaccine is safe and to study immune responses to it. - To study the effect of the MVA-EbolaZ booster on the immune response Eligibility: - Healthy adults ages 18-65.
Background: - Ebola is a viral infection that can spread quickly and causes life-threatening disease. Right now there is an Ebola outbreak in many countries in West Africa. There are no approved treatments for Ebola. But possible treatments are being developed. Researchers need to study these treatments to see if they help people get better. Objective: - To identify possible Ebola treatments. Also, to learn if adding 1 or more experimental drugs to advanced Ebola care can reduce the risk of death. Eligibility: - People who have recently been diagnosed with Ebola, usually by a test called the Polymerase Chain Reaction (PCR), and have been hospitalized in an isolation unit for treatment. Design: - Participants will be randomly assigned to Group A or B. Both groups will get advanced level care. One group will also get an experimental drug. - Participants may have blood tests. They may have another PCR test. - Researchers will try to learn how the participant got Ebola. - Participants put in the experimental drug group may start taking medicine within 24 hours of enrollment. It may be given by mouth or intravenously. Additional doses may be needed. - Participants may have a series of timed blood tests over the first 24 to 48 hours after they take the medicine. - Blood will be drawn frequently. Other body fluids (urine, stool, vaginal fluid, etc.) may also be collected. - Participants will be followed for up to 60 days. They may be evaluated for any long-term effects of the experimental treatment(s). They may be asked to return for 1 or more outpatient visits. - For consenting participants, follow-up will be extended for up to one full year past Day 58 with contact/visits every 1-3 months to assess for a history of signs or symptoms potentially consistent with late onset of virologic relapse syndrome.
The purpose of this study is to evaluate the safety, reactogenicity and immunogenicity of different formulations of a single intramuscular dose of GSK Biologicals' investigational RSV vaccine, in healthy, non-pregnant women aged 18 to 45 years.
The purpose of this study is to determine if the use of inhaled beclomethasone after a community-acquired respiratory viral infection in a lung transplant recipient decreases the risk of the subsequent development of chronic lung allograft dysfunction.
The primary objective of this study is to evaluate the antiviral efficacy of treatment with ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) therapy at the time of liver transplantation and through 4 weeks posttransplant in adults with genotype 1 or 4 hepatitis C virus (HCV) infection who are undergoing primary liver transplantation.
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of a single subcutaneous dose of UB-621 in healthy volunteers.
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) in participants with chronic genotype 1, 2, 4, 6 or indeterminate HCV infection who received placebo in the Gilead-sponsored study GS-US-342-1138.
This is an emergency, phase 2/3, open-label, non-randomized, clinical trial that will evaluate Convalescent Plasma (CP) added to standardized supportive care (SC) in patients with confirmed Ebola Virus Disease (EVD). No patient will be refused CP when compatible products are available and all efforts will be made to maximize CP availability during the study. EVD patients recruited during the period before CP becomes available or for whom no compatible CP is available will be given SC and will be followed for study outcomes. Data from these SC patients will be the used as comparator in the analysis of the study. The primary objective of the study is to assess if CP + SC improves the 14 day survival of patients, compared to SC alone. The Investigators aim to enroll a total number of 130 - 200 patients who will be treated treated with CP assuming equal numbers of patients treated with SC alone. If there would be insufficient patients treated with SC, patients treated at the research site prior to study start may be included in the comparison group. Patients will be recruited in the Ebola Treatment centre managed by Medecins Sans Frontieres (MSF) in Conakry, Guinea. All patients and/or relatives presenting at the centre will be informed about the study, and will be invited to provide consent at the time of admission inside the treatment centre. Only patients for whom ebola infection is confirmed with polymerase chain reaction (PCR) will be enrolled in the study. After inclusion, eligibility to the intervention will be reassessed on regular intervals. If the eligibility criteria are not met by 48 hours after inclusion, only SC will be continued. In line with the guidance of the World Health Organization (WHO), two units of CP will be given. EVD patients will be transfused with ABO-compatible CP using standard procedures. Details on the modalities of transfusion can be found in the WHO guidance document and the MSF guidelines on blood transfusion. All patients will be under close observation for transfusion-related adverse reactions during and up to 4 hours after transfusion. 24 hours after the start of transfusion, a blood sample will be collected for viral load assessment. All other aspects of patient management will be according to MSF clinical guidelines. The decision to discharge a patient should be taken on clinical grounds, but can be supported by the laboratory results. After discharge, the patient will be followed up by the study team until day 30.
