Brief Summary
The purpose of this study is to evaluate the potential for systemic exposure of aminolevulinic acid (ALA) and protoporphyrin IX (PpIX) when applied topically under occlusion, in a maximal use setting in patients with multiple actinic keratoses (AK) involving the upper extremities.

Outcome Measures
Primary Outcomes (9)
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.
2 days
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.
2 days
AUCt
AUCt is the area under the baseline corrected plasma concentration-time profile up to the last quantifiable/non-negative plasma concentration
0, 15, 30 minutes, and 1, 2, 4, 8, 12, 16, 24 hours post-dose
The Terminal Exponential Half-life (T1/2,z) for ALA
The terminal slope was calculated by linear least squares regression of the log plasma concentration-time data. The terminal exponential half-life (T1/2,z) will be calculated as 0.693 divided by the absolute value of slope.
2 days
Maximum Baseline Corrected Plasma Concentration (Cmax) for PpIX
Maximum baseline corrected plasma concentration (Cmax) for PpIX over the 48 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.
2 days
Time at Which Cmax is Attained (Tmax) for PpIX
Time of the maximum baseline corrected plasma concentration for PpIX 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.
2 days
AUCBL for PpIX
The area under the concentration time-curve assuming the baseline observed plasma concentration existed from time 0 to tlast.
0, 15, 30 minutes, and 1, 2, 4, 8, 12, 16, 24, 36 and 48 hours post-dose
AUCt for PpIX
The area under the observed plasma concentration time-curve from time 0 to the last quantifiable plasma concentration.
0, 15, 30 minutes, and 1, 2, 4, 8, 12, 16, 24, 36 and 48 hours post-dose
AUCt/AUCBL for PpIX
The ratio of AUCt to AUCBL for PpIX
0, 15, 30 minutes, and 1, 2, 4, 8, 12, 16, 24, 36 and 48 hours post-dose
