Efficacy and Safety of Painless 5-aminolevulinic Acid Photodynamic Therapy for Moderate and Severe Acne Vulgaris

November 23, 2020 updated by: Shanghai Dermatology Hospital

Efficacy and Safety of Painless 5-aminolevulinic Acid Photodynamic Therapy for the Treatment of Moderate and Severe Acne Vulgaris-- A Multi-center, Randomized Controlled Clinical Trial

This study is being done to compare a new, continuous illumination and short Incubation time regimen of 5-aminolevulinic acid photodynamic therapy (painless ALA- PDT) to low-dose and conventional dose of oral isotretinoin for treatment of moderate or severe acne vulgaris. The hypothesis is that the painless ALA- PDT will be equally or more efficacious as oral isotretinoin, and taking effect more quickly with less adverse effect.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Painless Photodynamic Therapy(P-PDT) group
The painless photodynamic therapy group underwent narrow-band light-emitting diode (LED) irradiation (630 nm; 150 J/cm2) after applying 5% 5-aminolevulinic acid(ALA) cream for 30min. A repeat treatment was administered once weekly for a maximum of 5 times. Blood samples, urine routine, blood biochemistry and electrocardiogram were performed before treatment and after treatment.
Aminolevulinic acid photodynamic therapy
Active Comparator: conventional-dose isotretinoin group
Patients in the conventional-dose isotretinoin group were given oral isotretinoin 0.5 mg/kg daily for 6 months, and the cumulative dose was 90 mg/kg. Time for subsequent visit: once every two weeks during the 1st and 2nd months, monthly during 3rd to 6th months. Blood samples, urine routine, blood biochemistry and electrocardiogram were performed before treatment and 2nd , 6th months after treatment.
Conventional-dose isotretinoin
Active Comparator: low-dose isotretinoin group
Patients in the low-dose isotretinoin group were given oral isotretinoin 0.2 mg/kg daily for 6 months, and the cumulative dose was 36 mg/kg. Time for subsequent visit: once every two weeks during the 1st and 2nd months, monthly during 3rd to 6th months. Blood samples, urine routine, blood biochemistry and electrocardiogram were performed before treatment and 2nd , 6th months after treatment.
low-dose isotretinoin

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The clearance rate of Moderate or Severe Acne
Time Frame: The clearance rate of Moderate or Severe Acne will be measured at 1st month after the last treatment
The clearance rate of Moderate or Severe Acne will be measured at 1st month after the last treatment
The clearance rate of Moderate or Severe Acne will be measured at 1st month after the last treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain assessment
Time Frame: immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute and 2nd hour, 12th hour, 24th hour and 48th hour after treatment
The pain will be assessed using Visual Analogue Scale (NRS) with a score range of 0-10. The higher the score, the greater the pain, with 0 being no pain and 10 being the most unbearable pain. Pain will be measured at different time points during and after every treatment (including immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute and 2nd hour, 12th hour, 24th hour and 48th hour after treatment.
immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute and 2nd hour, 12th hour, 24th hour and 48th hour after treatment
