Hepatitis B
Conditions
Brief summary
This study evaluates the addition of birinapant in subjects with chronic Hepatitis B who are currently receiving anti-viral therapy with either tenofovir or entecavir. Patients will receive either birinapant or placebo in addition to their anti-viral therapy.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Number of participants with adverse events | From Screening through end of study, up to 13 weeks |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pharmacokinetics of birinapant (in plasma): maximum concentration (Cmax), time of maximum concentration (Tmax), area under the curve (AUC) extrapolated to time infinity, AUC from dosing to last quantifiable concentration | Day -1 through Day 26 | — |
| Pharmacokinetics of birinapant (in plasma): terminal elimination half-life (t1/2), clearance (CL), terminal disposition rate constant,volume of distribution (Vdss) | Day -1 through Day 26 | — |
| Pharmacokinetics of oral antiviral medication (tenofovir or entecavir): Cmax, Tmax, AUC from dosing to last quantifiable concentration, t1/2, CL, terminal disposition rate constant, Vdss | Day -1, Day 1 and Day 22 | — |
| Hepatitis B markers (Determine levels of HBsAg, HBeAg, HBV DNA, and HBsAb) | Screening through Day 29 | Determine levels of HBsAg, HBeAg, HBV DNA, and HBsAb |
| Pharmacodynamic effect of birinapant on cIAP1 and cIAP2 levels in peripheral blood mononuclear cells (PBMC) and levels of cluster of differentiation 4 and 8 (CD4+, CD+8) lymphocytes | Screening through Day 29 | — |
