Trial Outcomes & Findings for Maximal Use Systemic Exposure Study of Levulan Kerastick (MUSE 2) (NCT NCT02628236)

NCT ID: NCT02628236

Last Updated: 2017-09-18

Results Overview

Timeframe: 2 days

Population: T1/2,z could not be determined in 11 subjects

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.

PRIMARY outcome

Timeframe: 2 days

Population: For 50% of the subjects, more than 50% of the PpIX plasma concentrations following topical application of ALA HCI were less than the predose plasma concentration. Therefore, negative values were set to 0 to evaluate median baseline corrected plasma concentration.

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.
