The Patient-Reported Outcomes Project of HCV-TARGET
Hepatitis CChronic1 moreThe PROP UP research study is funded by The Patient Centered Outcomes Research Institute (PCORI). PROP UP is a multi-centered prospective observational study that will evaluate all-oral treatment regimens for chronic hepatitis C viral (HCV) infection regarding several patient-reported outcomes (PROs) such as HCV-associated symptoms, treatment side effects, medication adherence, out of pocket costs, comorbid conditions, and long-term benefits of cure and harms of treatment to compare PROs of different treatment regimens, treatment durations, and patient subgroups. Participants will be recruited from 9 U.S. liver centers. Approximately 1920 patients with HCV infection who are prescribed a regimen containing Sofosbuvir/Ledipasvir(SOF/LED), SOF/Velpatasvir(SOF/VEL), Grazoprevir/Elbasvir(GRZ/ELB), OBV/PTV/r + DSV (PRoD), or daclatasvir/SOF (DAC/SOF) will be recruited and approximately 1600 patients who are approved and begin HCV treatment will be enrolled in the longitudinal study. PRO surveys will be evaluated before, during and after HCV treatment. PROP UP is a collaborative effort between behavioral and biomedical researchers, a patient engagement group and a patient advocacy organization.

Chronic Hepatitis CGenotype 1This 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.
HBV Virions Bound Proteins
Hepatitis B Virus InfectionThe emergence of hepatocellular carcinoma (HCC) has prompted a search for a thorough understanding of the biology of one of its major causative agents, the hepatitis B virus (HBV). HBV particles acquire via budding and encapsidation cellular proteins. There is mounting evidence on several viral species that virion-bound proteins are prone to be involved either at the replication, budding/egress or entry/release steps of the viral cycle. Identifying such targets may yield ideal candidates for gaining insight on the dependence of HBV upon a restricted subset of host proteins, therefore providing refined sets of genetically stable targets for therapy. This project's goals are to set up adequate conditions for robust and reproducible purification of HBV virions in clinical samples, followed by the identification of their HBV-bound host proteins and the characterization of their functions. Proteomics profiling of HBV particles purified from clinical samples will be overlaid with proteins identified and characterized in cell culture grown HBV particles, using clinical biomarker discovery grade criteria. Targets identified in both samples sets will be subjected to in vitro investigations using HBV-replicating cells. Conventional biochemical and imaging methods will be used in order to: (i) ascertain their physical association with HBV virions; (ii) define the modalities of their interaction with HBV proteins; (iii) decipher the topology and subcellular localization of their association with HBV proteins and virions; (iv) quantitatively assess their functional involvement in particle budding, egress or secretion and infectivity. A candidate that yielded satisfactory results in these experiments will be disclosed and further investigated at the level of structural biology, in collaborative research programs.
