Primary Outcome Measures:
  • Incidence of dose limiting or intolerable treatment related AEs [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Incidence of treatment emergent AEs [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Incidence and severity of hypoglycemic events [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Incidence of abnormal laboratory findings [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Vital signs [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Incidence of anti-drug antibodies [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Severity of treatment emergent AEs [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Causal relationship of treatment emergent AEs [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • Blood pressure [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]
  • ECG parameters [ Time Frame: 127 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Area under the Concentration-Time Curve (AUC) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption.

  • Apparent Oral Clearance (CL/F) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

  • Maximum Observed Plasma Concentration (Cmax) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
  • Plasma Decay Half-Life (t1/2) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

  • Volume of Distribution at Steady State (Vss) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of a drug. Steady state volume of distribution (Vss) is the apparent volume of distribution at steady-state.

  • Accumulation ratio (R) [ Time Frame: 127 days ] [ Designated as safety issue: No ]
