Active clinical trials for "Hepatitis A"

Background: Stem cell transplants (SCTs) are important in treating many diseases. There are two main types of transplants. Autologous stem cells come from the person getting the cells. Allogeneic stem cells come from another person. The risk of hepatitis B virus (HBV) is high after allogeneic SCT. Even if a person receives the HBV vaccine after transplant, he or she may not really be immune to HBV. The person may become immune only after repeated series of the vaccine. Researchers need to learn more about the HBV vaccine in people after transplant so it can be most effective. Objective: To assess the rate of achieved HBV immunity for people who had an SCT who did not become immune with the first vaccine series and require 2 or more series. Eligibility: People who have had at least 1 dose of the HBV vaccine and were enrolled in these protocols: 99-H-0050, 10-H-0154, and 08-H-0046 Design: Participants will be screened in the other protocols. Participants data and medical charts will be reviewed. Data from up to 350 participants who had transplants before March 2016 will be reviewed. Participants data will be collected: Demographic data Type of transplant Type of donor Clinical information about the transplant...

This multi-center, observational study will examine the clinical use and outcomes of pegylated interferon (PEG-IFN) alfa-2a and ribavirin combination (PEGASYS RBV) in participants with chronic hepatitis C (CHC). Study visits will be scheduled for baseline, 12, 24 and 48 weeks after baseline. An additional follow-up visit at week 72 will be required for participants with an HCV genotype other than 2 or 3. Quality of life data will be collected at baseline, and at each follow-up visit.

Activation of the immune system against a pathogen can be considered one of the most effective interventions in the field of infectious diseases. Transgene is developing a therapeutic vaccine "TG1050" for the treatment of patients with chronic and treated Hepatitis B. This biotherapy compound is for the development of T cellular immune response in these patients in order to achieve the total elimination of infected cells. Therefore it is necessary to have measures of ways to assess accurately and reliably the presence of such a response in the study subjects.

The primary objective of this post-marketing surveillance study is to collect and assess data related to the safety and effectiveness of Harvoni® (ledipasvir/sofosbuvir (LDV/SOF)) treatment regimen, per the approved Korea prescribing information for Harvoni, in routine clinical practice in Korea and to report the results to the Ministry of Food and Drug Safety (MFDS). Participants will be treated as part of routine practice at Korean healthcare centers by accredited physicians.

This study seeks to assess the durability of response and persistence of resistance to ombitasvir/ paritaprevir/ritonavir in Japanese participants who enrolled in a Phase 2 or 3 clinical study with these agents for the treatment of chronic hepatitis C.

This study seeks to assess the effectiveness, patient reported outcomes, work productivity and healthcare resource utilization of the interferon-free regimen of paritaprevir /ritonavir (r) - ombitasvir, ± dasabuvir ± ribavirin (RBV) in participants with chronic hepatitis C in a real life setting across clinical practice populations.

This study seeks to provide evidence of the effectiveness and obtain patient reported outcome (PRO) data for the interferon-free regimen of paritaprevir (PTV)/ritonavir (r) + ombitasvir (OBV), + dasabuvir (DSV), +/- ribavirin (RBV) in participants with chronic hepatitis C (CHC) in a real life setting across clinical practice patient populations in Romania.

The purpose of this study is to describe current rescue treatment pattern for nucleot(s)ide analogue (NA) resistance and assess the real-world treatment outcomes and health resources utilization of rescue treatments for drug resistance in a clinical cohort of Chinese patients with chronic hepatitis B (CHB).

The purpose of this study is to further evaluate the immunogenicity and safety of 10μg/0.5ml Recombinant Hepatitis B Vaccines(Saccharomyces Cerevisiae) in the Healthy Neonates.

This protocol is being conducted to comply with the direct request from the Taiwan Food and Drug Administration (TFDA) for a 60-month intensive pharmacovigilance protocol of patients with known hepatitis B (HBV) or hepatitis C (HCV) infection, regardless of control on antiviral therapy in Taiwan and who are treated with ipilimumab for advanced (unresectable, recurrent or metastatic) Melanoma.
