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.

Arm Intervention/treatment
Experimental: Antiviral Therapy & Birinapant
Antiviral therapy (tenofovir 300 mg or entecavir 0.5 mg) taken once daily by mouth, and birinapant administered as a 30 minute IV infusion once weekly for four weeks.
Drug: Antiviral Therapy (tenofovir or entecavir)
Drug: Birinapant
Placebo Comparator: Antiviral Therapy & Placebo
Antiviral therapy (tenofovir 300 mg or entecavir 0.5 mg) taken once daily by mouth, and placebo (for birinapant) administered as a 30 minute infusion once weekly for four weeks.
Drug: Antiviral Therapy (tenofovir or entecavir)
Drug: Placebo (for birinapant)



Primary Outcome Measures :
  1. Number of participants with adverse events [ Time Frame: From Screening through end of study, up to 13 weeks ]

Secondary Outcome Measures :
  1. 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 [ Time Frame: Day -1 through Day 26 ]
  2. Pharmacokinetics of birinapant (in plasma): terminal elimination half-life (t1/2), clearance (CL), terminal disposition rate constant,volume of distribution (Vdss) [ Time Frame: Day -1 through Day 26 ]
  3. 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 [ Time Frame: Day -1, Day 1 and Day 22 ]
  4. Hepatitis B markers (Determine levels of HBsAg, HBeAg, HBV DNA, and HBsAb) [ Time Frame: Screening through Day 29 ]
    Determine levels of HBsAg, HBeAg, HBV DNA, and HBsAb

  5. 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 [ Time Frame: Screening through Day 29 ]
