Comparison of Three Hepatitis B Vaccination Regimens in HIV-Positive Youth

2017年2月27日 更新者:University of North Carolina, Chapel Hill

A Randomized, Open-Label Trial of Three Hepatitis B Vaccination Schemas in HIV-Positive Youth

Hepatitis B is a contagious virus that can damage a person's liver. It can be prevented by vaccination, but for many HIV-positive people, the vaccines do not help them achieve adequate protection against this virus. In an attempt to improve response to vaccination and achieve protection from hepatitis B, this trial will compare the immune system response to 3 hepatitis B vaccine regimens in HIV-positive adolescents 12 through 24 years of age.

研究概览

详细说明

Suboptimal response to hepatitis B vaccination in HIV+ adults and children has been well documented in the literature. Given the importance of preventing hepatitis B virus (HBV) co-infection in HIV+ youth and the poor response rates in this population, this study will attempt to improve the immediate and long-term sero-response rates by undertaking a randomized, open-label trial of three hepatitis B vaccination schemas, as follows:

  1. standard adult dosing of HBV-only vaccine: Engerix-B 20 mcg at Entry, Week 4 and Week 24
  2. increased adult dosing of HBV-only vaccine: Engerix-B 40 mcg at Entry, Week 4 and Week 24
  3. standard adult dosing of combined HBV/hepatitis A virus (HAV) vaccine: Twinrix 720 enzyme immunoassay (EIA) HAV Ag plus 20 mcg HBsAg at Entry, Week 4 and Week 24.

This study will also describe the safety of administration of an increased dose of the hepatitis B vaccine in this population. In general, patients undergoing dialysis who have received the dosing regimen recommended for immunocompromised individuals have tolerated the vaccine series well.

Design: This is a stratified, block-randomized, open-label trial of three hepatitis B vaccination schemas in HIV-infected and HBV-uninfected youth. Once randomized, there will be a total of 6 study visits in a 72 week period. Vaccination will occur at Entry, Week 4 and Week 24. Primary sero-response will be evaluated at Week 28 and sustainability of response will be evaluated at Weeks 48 and 72 for those who achieve a primary antibody response of >= 10 IU/ml. Primary non-responders (antibody response of < 10 IU/ml) will be provided with a booster vaccine using the increased-dose Engerix-B vaccine at Week 48 and evaluated for responsiveness at Week 72.

Baseline through Week 72
Safety of 3 Hepatitis B Vaccine Regimens in HIV+ Youth - ADVERSE EVENTS BY INTERVENTION ARM ON STUDY - DEFINITELY RELATED
大体时间:Baseline through Week 72
The number of AEs was described by study arm. The proportion of subjects with clinical AEs in Arms 1 and each of the two alternative strategy arms (Arm 2 and Arm 3)were compared to assess whether or not there is a difference in subjects with any grade toxicity.
Baseline through Week 72
Safety of 3 Hepatitis B Vaccine Regimens in HIV+ Youth - ABNORMAL LABORATORY VALUES GRADE 2 OR ABOVE BY INTERVENTION ARM ON STUDY
大体时间:Baseline through Week 72
The number of adverse events and subjects with the events were described by study arm. The proportion of subjects with abnormal labs in Arms 1 and each of the two alternative strategy arms (Arm 2 and Arm 3) were compared to assess whether or not there is a difference in subjects with grade 3 or 4 toxicity. The laboratory events included are AEs classified as probably, possibly, or definitely related to study drug as classified by the Site Investigator.
Baseline through Week 72
Response Rates in HIV+ Youth Within Each Study Arm by Study Duration
大体时间:Entry through Week 72
Within each arm, the duration of response in HIV-infected youth was analyzed for all subjects who were responders at 28 weeks. The possible values for response duration could be 20 weeks or less (responder at 28 weeks but not at 48 weeks), 20 to 44 weeks (responder at 28 and 48 weeks but not at 72 weeks), or greater than 44 weeks (responder at 28, 48, and 72 weeks). A response of greater than 20 weeks includes those who responded after 20 weeks, but whose exact response duration was unknown.
Entry through Week 72
Sero-Response to Hepatitis B Surface Antigen; Predictor: STUDY ARM
大体时间:Week 28
Response rate associated with the participant's study arm, baseline CD4 count, and interaction term that reflects how subjects in Arm 2 responded differently depending on their CD4 count. Response is defined as greater than or equal to 10 IU/mL of serum being present; non-response is defined as less than 10 IU/mL.
