Primary Outcome
Outcome
TimePoints
To achieve bioequivalence between both test and reference product by both primary and secondary PK endpoints.
The primary PK endpoint is to demonstrate bioequivalence for the
following steady state PK parameters:
Maximum plasma concentration at steady state.
AUC during a dosage interval at steady state.
Concentration at the end of the dosing interval at steady state.
Average concentration during a dosing interval (Cavg,ss)
Time until Cmax,ss is reached (Tmax,ss).
Swing in steady state pharmacokinetics (Swing).
Degree of fluctuation in the steady state pharmacokinetics (% Fluctuation).
Minimum plasma concentration at steady state (Cmin,ss).
Safety endpoint: To summarize safety data using descriptive statistics, of frequency/severity of, Adverse Events (AEs), of
test product in comparison with the reference product.
