Efficacy and Safety Study of GS-9450 Treatment for 6 Months in Patients With Chronic Hepatitis C...
HCV InfectionThis is a Phase 2b, randomized, double-blind, parallel-group, placebo-controlled, multicenter study investigating the safety, tolerability and efficacy of two oral doses of GS-9450 in adults with chronic Hepatitis C Virus (HCV). Approximately 240 subjects 18-65 years of age who meet study entry criteria will be randomized (in other words, selected at random, like flipping a coin) to one of three treatment groups (80 subjects per treatment group) as follows:GS-9450 10 mg once daily,GS-9450 40 mg once daily, or matching placebo once daily. Following randomization, subjects will return within seven business days for a Baseline (Day 1) visit, at which time study medication will be dispensed and subjects will enter a 26 week treatment phase. During the treatment phase, subjects will receive study drug once daily for 24 weeks and then taper off of study drug over the following 2 weeks by receiving study drug once every other day for one week and then every 3 days for one week. Following completion of the treatment phase, subjects will enter a 4-week off-treatment follow-up phase.
Treatment of SARS-CoV-2 Virus Disease (COVID-19) in Humans With Hemopurifier® Device
COVID-19This is an Early Feasibility Study (EFS) investigating the use of the Hemopurifier® in the treatment of SARS-CoV-2 Virus Disease (COVID-19).
Anti-SARS Cov-2 T Cell Infusions for COVID 19
SARS-CoV 2Viral Infection1 moreThis is a dose-finding safety trial followed by a randomized pilot trial comparing administration of SARS-CoV2-specific T cells (SARS-CoVSTs) to standard of care treatment in hospitalized patients with COVID19 who are at high risk of requiring mechanical ventilation. The SARS-CoVSTs lines have been made at Baylor College of Medicine from healthy donors who have made a full recovery from COVID19. These cell lines were frozen for later use and will be thawed and used to treat patients who meet the eligibility criteria.
A First in Human Study of AL-611 in Healthy Volunteers and Patients With Hepatitis C Virus Infection...
Hepatitis CThis randomized, double-blind, placebo-controlled, 3-part study will assess the safety, tolerability, pharmacokinetics (PK), and antiviral activity (Part 3 only) of orally administered AL-611 in healthy volunteers (HV; Parts 1-2) and subjects with CHC (Part 3). Part 1: HV will receive 1 of 5 single ascending doses (SAD) of AL-611 Part 2: Eight HV from Cohort 3 in Part 1 are planned to receive a second single dose of AL-611 or placebo (as per their randomized assignment in Part 1) in a fed state after a washout period Part 3: Subjects with CHC infection will receive 1 of 3 planned multiple ascending doses (MAD)
Tobacco Use and the Risk of COVID-19 and Adverse Outcomes
COVID-19Respiratory Tract Infections6 moreThis is an observational study of pooled population-based samples in three Nordic countries. Country-specific data has already been analysed in previous studies in Sweden, Finland, and Norway. The primary objective is to examine the association between tobacco use, the risk of SARS-CoV-2 infection, and adverse Outcomes using pooled population-based samples.
A Study of Safety and Efficacy of ATI-2173 and Vebicorvir in Combination With Tenofovir Disoproxil...
Chronic Hepatitis bThis is a randomized, double-blinded, placebo-controlled, multi center, dose ranging study of safety and efficacy in volunteers with chronic hepatitis B virus infection. Volunteers will be administered multiple oral doses of ATI-2173 vebicorvir in combination with tenofovir disoproxil fumarate and assessed for safety and efficacy including blood tests to show how the body metabolizes and eliminates the investigational drug as well as how the drug effects the virus infection.
GS-5885, GS-9451 With Peginterferon Alfa 2a (PEG) and Ribavirin in Treatment-Naïve Subjects With...
Chronic Hepatitis CThis is a Phase 2, randomized, open-label exploratory study that will examine the antiviral efficacy, safety, and tolerability of Response guided treatment (RGT) with GS-5885 + GS-9451 + PEG/RBV (6 or 12 weeks), or Peginterferon Alfa 2a (PEG)/Ribavirin (RBV)alone (24 weeks) in treatment naïve subjects with chronic Hep C (HCV) infection with genotype (GT) 1 and IL28B CC genotype.
A Prospective, Open Label, Phase 1 Safety Study of Passive Immune Therapy During Acute Ebola Virus...
Acute Ebola Virus DiseaseThe objective of this Phase 1 safety study is to provide access to the potential therapeutic benefit of EBOV convalescent plasma containing antibodies to EBOV. The risk of exposure to plasma from donors who may be infected with other transfusion-transmitted pathogens, not detectable by current licensed donor testing procedures, will be mitigated by using pathogen inactivation to minimize the risk of the TTI from these donors, who would otherwise be deferred and ineligible for blood donation.
ANRS HB 05 Multicenter Study Evaluating Efficacy and Safety of Clevudine Monotherapy Versus Tenofovir...
HBe Negative Chronic Hepatitis BHepatitis B Viral InfectionFor chronic HBV infection, an optimal pharmacological agent to promote recovery from chronic HBV infection would be one that inhibits HBV DNA polymerase, combined with the clearence from the liver of cccDNA to block HBV reactivation after the circulating viral burden has been eliminated by therapy. The activity of clevudine on cccDNA in combination with its potent antiviral activity on HBV polymerase makes it the optimal agent in combination with tenofovir for this protocol.
In UTERO Treatment of Cytomegalovirus Congenital Infection With Valacyclovir
Viral DiseaseCytomegalovirus InfectionThe infection with cytomegalovirus (CMV) is the first cause of congenital neurological handicap of infectious origin. It is probable that the neonatal viral load is correlated with becoming of infected new-born babies. Among the active antiviral treatments against CMV, valacyclovir is the only whose fetal and maternal tolerance was evaluated during the pregnancy. Its harmlessness and its aptitude to decrease the CMV viral load justify to evaluate it in a study against placebo. Decrease the fetal viral load could make possible to decrease symptomatology neonatal in a group of infected fetuses.
