NCT ID: NCT01957085 Completed - Hepatitis C Clinical Trials

Undiagnosed Hepatitis C Infection in an Urban Hospital

Start date: June 2014
Phase:
Study type: Observational

The Centers for Disease Control and Prevention estimates that there are approximately 3.2 million people in the United States infected with hepatitis C and a significant percentage of these patients are unaware of their diagnosis. This study will attempt to determine the point prevalence of undiagnosed hepatitis C infection in an urban hospital population. All patients admitted to the hospital on two separate days will have hepatitis C testing done on leftover serum and plasma that was collected as part of routine inpatient lab work. Our primary goal is to determine the number of undiagnosed hepatitis C infected patients in our hospitalized population. We will also compare these rates to specific demographic characteristics, such as age, race, gender, zip code and type of insurance to see if any associations exist between these demographics and undiagnosed hepatitis C infection.

NCT ID: NCT01951677 Completed - Clinical trials for Exposure to Hepatitis B Virus

Safety and Efficacy Study of Adjuvanted Prophylactic Hepatitis B Vaccine

Start date: July 2013
Phase: Phase 1
Study type: Interventional

There is a need for more effective and better-tolerated hepatitis B vaccines for low responder high-risk populations including patients with renal impairment and/or diabetes mellitus and those aged over 40 years. Several approaches are available to enhance the potency of hepatitis B virus vaccines including use of the more highly immunogenic antigens, replacing alum with potentially more effective adjuvants, and increasing the dose of vaccine antigen. A combination of these strategies is being tested in this study to identify the most promising candidate approaches to take forward into advanced clinical development

NCT ID: NCT01949857 Completed - Hepatitis A Clinical Trials

The Immunogenicity and Safety of Inactivated and Live Attenuated Hepatitis A Vaccines

HAV
Start date: September 2013
Phase: Phase 4
Study type: Interventional

The purpose of this Phase 4 trial is to assess the safety, immunogenicity, three-year immune persistence of inactivated hepatitis A vaccine (HAV) and live attenuated HAV vaccine.

NCT ID: NCT01948193 Completed - Hepatitis B Clinical Trials

Study of DTaP-IPV-Hep B-PRP~T Combined Vaccine in Indian Infants Previously Given a Dose of Hepatitis B Vaccine at Birth

Start date: February 2014
Phase: Phase 3
Study type: Interventional

The purpose of this study is to describe the immunogenicity and safety of a novel DTaP- IPV- Hep B-PRT~T fully liquid combined hexavalent vaccine (Hexaximâ„¢) administered at 6, 10 and 14 weeks of age in infants born to mothers documented to be serum anti-hepatitis B surface antigen (HBsAg) serology negative in India. Primary Objective: - To evaluate the immunogenicity of the study vaccine in terms of seroprotection [diphtheria toxoid, tetanus toxoid, poliovirus types 1, 2 and 3, Haemophilus influenzae type b (Hib) polysaccharide (PRP), hepatitis B (Hep B)] and vaccine response for pertussis antigens [pertussis toxoid (PT) and filamentous haemagglutinin (FHA)] one month after the third dose. Secondary Objectives: - To further describe the immunogenicity of the study vaccine, before the first dose and one month after the third dose. - To describe the safety after each and any doses of the study vaccine.

NCT ID: NCT01940471 Completed - Clinical trials for HBeAg-positive Chronic Hepatitis B

Study to Compare Tenofovir Alafenamide (TAF) Versus Tenofovir Disoproxil Fumarate (TDF) in Participants With Chronic Hepatitis B Infection Who Are Positive for Hepatitis B e Antigen

Start date: September 11, 2013
Phase: Phase 3
Study type: Interventional

The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B virus (HBV) infection.

NCT ID: NCT01940341 Completed - Clinical trials for HBeAg-negative Chronic Hepatitis B

Study to Compare Tenofovir Alafenamide (TAF) Versus Tenofovir Disoproxil Fumarate (TDF) in Participants With Chronic Hepatitis B Infection Who Are Negative for Hepatitis B e Antigen

Start date: September 12, 2013
Phase: Phase 3
Study type: Interventional

The primary objective of this study is to compare the efficacy, safety, and tolerability of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF) in treatment-naive and treatment-experienced adults with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection.

NCT ID: NCT01939197 Completed - Chronic Hepatitis C Clinical Trials

A Multipart, Open-label Study to Evaluate the Safety and Efficacy of ABT-450/r/ABT-267 With and Without ABT-333 Coadministered With and Without Ribavirin in Adult With Genotype 1 or 4 Hepatitis C Virus (HCV) Infection and Human Immunodeficiency Virus, Type 1 Coinfection

TURQUOISE-I

Phase: Phase 2/Phase 3
Study type: Interventional

The primary objectives of this study are to assess the safety of ABT-450/r/ABT-267 with and without ABT-333 coadministered with and without ribavirin (RBV) for 12 and 24 weeks in HCV GT1- or 4-infected participants with HIV-1 coinfection and to evaluate the percentage of subjects achieving HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment.
