NCT04167982

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • The clearance rate of Moderate or Severe Acne

    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 Outcomes (1)

  • Pain assessment

    immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute and 2nd hour, 12th hour, 24th hour and 48th hour after treatment

Study Arms (3)

Painless Photodynamic Therapy(P-PDT) group

EXPERIMENTAL

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.

Procedure: Aminolevulinic acid photodynamic therapy

conventional-dose isotretinoin group

ACTIVE COMPARATOR

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.

Drug: Oral conventional-dose isotretinoin

low-dose isotretinoin group

ACTIVE COMPARATOR

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.

Drug: Oral low-dose isotretinoin
