Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

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.

Intervention Type PROCEDURE

Aminolevulinic acid photodynamic therapy

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.

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.
