Maximal Use Systemic Exposure (MUSE) Study of Levulan Kerastick
November 16, 2016 updated by: DUSA Pharmaceuticals, Inc.
A Pharmacokinetic Study of Levulan Kerastick (Aminolevulinic Acid HCl) for Topical Solution, 20% Under Maximal Use Conditions
The purpose of this study is to evaluate the potential for systemic exposure of aminolevulinic acid (ALA) when applied topically under occlusion, in a maximal use setting in patients with multiple actinic keratoses (AK) involving the upper extremities.

Measure Description |
Time Frame |
---|---|---|
AUCt
Time Frame: 0, 15, 30 minutes, and 1, 2, 4, 8, 12, 16, 24 hours post-dose
|
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
|
Maximum Baseline Corrected Plasma Concentration (Cmax) for ALA
Time Frame: 1 day
|
Maximum baseline corrected plasma concentration (Cmax) for ALA over the 24 hour sampling time period.
Blood samples wiere taken before ALA application and at 15 and 30 minutes, 1, 2, 4, 8, 12, 16 and 24 hours following study medication application.
|
1 day
|
Time at Which Cmax is Attained (Tmax) for ALA
Time Frame: 1 day
|
Time of the maximum baseline corrected plasma concentration for ALA measured at at 15 and 30 minutes, 1, 2, 4, 8, 12, 16 and 24 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.
|
1 day
|
The Terminal Exponential Half-life (T1/2,z)
Time Frame: 1 day
|
The terminal slope will be 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.
