Outcomes

Primary Outcome Measures

Maximum Baseline Corrected Plasma Concentration (Cmax) for ALA
Maximum baseline corrected plasma concentration (Cmax) for ALA over the 24 hour sampling time period. Blood samples were taken before ALA application and at 15 and 30 minutes, 1, 2, 4, 8, 12, 16, 24, 36 and 48 hours following study medication application.
Time at Which Cmax is Attained (Tmax) for ALA
Time of the maximum baseline corrected plasma concentration for ALA measured at at 15 and 30 minutes, 1, 2, 4, 8, 12, 16, 24, 36 and 48 hours following study medication application.If a maximum value occurred at more than one timepoint Tmax is defined as the first timepoint with this value.
AUCt
AUCt is the area under the baseline corrected plasma concentration-time profile up to the last quantifiable/non-negative plasma concentration
