Outcome Measures

Primary Outcome Measures :
  1. Maximum Plasma Concentration (Cmax) for SSP-002358 [ Time Frame: Assessed over 48 hours post-dose ]
    Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated.

  2. Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity (AUC 0→∞) for SSP-002358 [ Time Frame: Assessed over 48 hours post-dose ]
    Area under the plasma concentration versus time curve from time 0 to infinity. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.
