Keratosis, Actinic
Conditions
Brief summary
The primary purpose for this study is to assess recurrence of Actinic Keratosis in participants achieving complete response treated in earlier study.
Detailed description
This is a double-blind, multicenter, long-term follow-up study. The primary purpose of this study is to assess recurrence of Actinic Keratosis in participants treated with Methyl aminolevulinate hydrochloride (MAL) 16.8 percent (%) cream (CD06809-41) or vehicle cream in the treatment of thin and moderately thick, non-hyperkeratotic, non-pigmented actinic keratosis of the face and scalp when using daylight photodynamic therapy (DL-PDT), for participants achieving complete response of treated lesions at Final Visit in Study RD.06.SPR.112199 (NCT04085367).
Interventions
No intervention will be administered as a part of this study. Participants who received MAL cream in RD.06.SPR.112199 study will be rolled over in the study.
No intervention will be administered as a part of this study. Participants who received vehicle cream in RD.06.SPR.112199 study and achieved complete response, will be rolled over in the study.

Recruitment details
The study was conducted at 31 study centers in United States from 7 April 2020 to 1 September 2021. Participants who completed study RD.06.SPR.112199 (NCT04085367) and achieved complete response (CR) of all treated Actinic Keratosis (AKs) lesions at final visit of treatment, were continued to be followed in this for long-term follow-up (LTFU) study to assess recurrence.
Pre-assignment details
125 participants (87 in Methyl aminolevulinate hydrochloride (MAL) 16.8% cream group and 38 in vehicle cream group) from main study RD.06.SPR.112199 were enrolled and treated in this study. Study was terminated early as in main study, primary analysis did not show superiority of MAL 16.8% cream with DL-PDT over vehicle cream with DL-PDT as of participant complete response (CR), and the sponsor decided not to apply for marketing authorization for the MAL 16.8% cream in combination with DL-PDT.

Outcome results
Number of Participants With Recurrence of Any (>=1) Cleared Treated AK Lesions at Week 54
Participants with recurrence are defined as the participants with recurrence of any (greater than and equal to \[\>=\] 1) cleared treated AK lesions. Number of participants with recurrence of any (\>=1) cleared treated AK lesions at Week 54 was reported.
Time frame: At Week 54
Population: Safety population consisted of all enrolled participants and was to be used for all efficacy and safety analyses. Here, Overall Number of Participants Analyzed signifies those participants who were evaluable for this outcome measure.
