Maximal Use Systemic Exposure (MUSE) Study of Levulan Kerastick

NCT02281136 | Completed Phase 2 Results

• 1 other identifier: CP0110
• Study Type: interventional
• Target: 29
• Locations: 1 country
• Sites: 3

Brief Summary

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.

Conditions

Keratosis, Actinic

Keywords

Actinic keratosis

Outcome Measures

Primary Outcomes (4)

• 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 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 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

• 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)

  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.
