Active clinical trials for "Virus Diseases"

The purpose of this study was to compare the safety and efficacy of ABT-493/ABT-530 to the combination of sofosbuvir (SOF) and daclatasvir (DCV) in adults with genotype 3 (GT3) chronic hepatitis C virus (HCV) infection.

The purpose of this study is to determine whether Ingavirin ® dosed 30 mg daily is effective and safe in the treatment of influenza and other acute respiratory viral infections in the course of standard therapy in 3-6 years old patients.

The primary objective of this study is to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks in participants with chronic hepatitis C virus (HCV) infection.

This study seeks to assess the safety and efficacy of treatment with ombitasvir/paritaprevir/ritonavir and dasabuvir with low-dose ribavirin in non-cirrhotic, genotype 1a (GT1a) hepatitis C virus infected participants who are treatment-naïve or treatment-experienced with Interferon (IFN) or Pegylated Interferon (pegIFN) with or without Ribavirin (RBV).

This is a Phase 3b, prospective, multicenter, open-label, non-controlled study to assess the safety and effectiveness of immunoprophylaxis with the intramuscular (IM) administration of the liquid formulation of palivizumab for the prevention of RSV hospitalizations in infants at high risk (infants born at less than or equal to 35 weeks gestational age and less than or equal to 6 months of age at enrollment; or infants less than or equal to 24 months of age with a diagnosis of chronic lung disease [CLD] of prematurity requiring on-going medical treatment within the previous 6 months or infants less than or equal to 24 months of age with hemodynamically significant congenital heart disease [CHD]).

The purpose of this study is to determine whether Ingavirin ® dosed 60 mg daily is effective and safe in the treatment of influenza and other acute respiratory viral infections in 7-12 years old patients.

The primary objective of this study is to evaluate the antiviral efficacy, safety, and tolerability of therapy with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) and ribavirin (RBV) in participants with chronic genotype 1 or 2 hepatitis C virus (HCV) infection who have previously failed a direct-acting antiviral (DAA)-containing regimen.

The purpose of this study is to show superiority of simeprevir (SMV) in combination with sofosbuvir for 12 weeks versus a historical control. Historical control will be a composite of the observed historical sustained virological response at Week 12 (SVR12) rates of SMV in combination with (pegylated) interferon (PegIFN)/ribavirin (RBV) of the subpopulations in study HPC3011 (NCT01567735) and will depend on the percentage of treatment-naive, prior relapser, prior non-responder, interferon (IFN)-intolerant and other subjects enrolled in this study.

Allogeneic hematopoetic stem cell transplantation (SCT) is frequently complicated by life threatening viral reactivation. Conventional antiviral therapy is suboptimal for cytomegalovirus (CMV), adenovirus (AdV) and Epstein-Barr virus (EBV) and nonexistent for BK virus (BKV). An alternative approach to prevent viral reactivation is to infuse virus-specific cytotoxic T cells (CTL) prepared from the donor early after SCT. Such multivirus-specific CTL cells (MVST) have been successfully used in a number of centers to prevent or treat CMV, Ad and EBV. Activity of BKV-reactive cells has not been studied. Multi virus-specific T cells (MVST) are donor lymphocytes that are highly enriched for viral antigens and expanded in vitro before infusion into the transplant recipient. Viral reactivation is a particular problem inT cell depleted SCT. Median time to CMV reactivation is estimated as 28 days post T-depleted transplant, but infusion of MVST within the immediate post-SCT period has not been previously studied. This protocol will be the first of a planned series of cellular therapies to be layered on our existing T lymphocyte depleted transplant platform protocol 13-H-0144. The aim of this study is to determine the safety and efficacy of very early infusion of MVST directed against the four most common viruses causing complications after T-depleted SCT. GMP-grade allogeneic MVST from the stem cell donor will be generated using monocyte-derived donor dendritic cells (DCs) pulsed with overlapping peptide libraries of immunodominant antigens from CMV, EBV, Ad, and BKV and expanded in IL-7 and IL-15 followed by IL-2 for 10-14 days. A fraction of the routine donor leukapheresis for lymphocytes obtained prior to stem cell mobilization will be used to generate the MVST cells. MVST passing release criteria will be cryopreserved ready for infusion post SCT. Eligible subjects on NHLBI protocol 13-H-0144 will receive a single early infusion of MVST within 30 days (target day +14, range 0-30 days) post SCT. Phase I safety monitoring will continue for 6 weeks. Viral reactivation (CMV, EBV, Ad, BK) will be monitored by PCR by serial blood sampling. The only antiviral prophylaxis given will be acyclovir to prevent herpes simplex and varicella zoster reactivation. Subjects with rising PCR exceeding threshold for treatment, or those with clinically overt viral disease will receive conventional antiviral treatment. Patients developing acute GVHD will receive standard treatment with systemic steroids. These patients are eligible for reinfusion of MVST when steroids are tapered. The clinical trial is designed as a single institution, open label, non-randomized Phase I/II trial of MVST in transplant recipients, designed as 3-cohort dose escalation Phase I followed by a 20 subject extension Phase II at the maximum tolerated dose of cells. Safety will be monitored continuously for a period of 6 weeks post T cell transfer. The primary safety endpoint will be the occurrence of dose limiting toxicity, defined as the occurrence of Grade IV GVHD or any other SAE that is deemed to be at least probably or definitely related to the investigational product. The primary efficacy endpoint for the phase II will be the proportion of CMV reactivation requiring treatment at day 100 post transplant. Secondary endpoints are technical feasibility of MSVT manufacture, patterns of virus reactivation by PCR, and clinical disease from EBV, Ad, BK, day 100 non-relapse mortality.

Background: Ebola virus can cause serious illness or death. No medicines are approved to treat it. Researchers need to test new medicines to see if they help people recover from Ebola and are safe to give. They need to test the drugs and compare them in a controlled way. Researchers want to test 4 drugs with people who have Ebola and are in treatment centers. Objective: To study the safety and effectiveness of 4 drugs for people with Ebola virus. Eligibility: People of any age with Ebola infection who are in treatment centers Design: Participants will be screened with questions, medical history, and blood tests. Participants will be randomly assigned to get 1 of 3 study drugs: ZMapp by IV over about 4 hours. It will be given 3 times, 3 days apart. Remdesivir by IV over about 1 hour. It will be given once a day for 10 days. Mab114 by IV for 30-60 minutes. It will be given 1 time. REGN-EB3 by IV for about 2 hours. It will be given 1 time. For at least a week, participants will stay in isolation in a clinic. They will: Get supportive care and be monitored Have a small plastic tube (IV) put in an arm vein for several days to give fluids and collect blood. Get their study drug. Be monitored for disease signs and drug side effects. They may get medicines for side effects. Have blood and urine tests. Participants will stay in the clinic until they finish the study drug and are well enough to leave. Participants will have 2 follow-up visits over 2 months. They will answer questions and give blood and semen samples. ...
