Conventional Photodynamic Therapy vs. Painless Photodynamic Therapy for Small Genital Warts

May 27, 2019 updated by: Xiuli Wang, Shanghai Dermatology Hospital

Conventional Photodynamic Therapy vs. Painless Photodynamic Therapy for Small Genital Warts：a Randomized, Open-label Trial

This study is being done to compare a new, continuous illumination and short Incubation time regimen of aminolevulinic acid photodynamic therapy（ALA-PDT) to a conventional regimen for treatment of small genital warts. The hypothesis is that the continuous illumination approach will be less or even no painful, but equally efficacious, as the old regimen.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

EXPERIMENTAL: Painless Photodynamic Therapy（P-PDT）
The painless photodynamic therapy（P-PDT）group underwent narrow-band light-emitting diode (LED) irradiation (630 nm; 400 J/cm2) after applying 20% 5-aminolevulinic acid（ALA）cream for 30min. A repeat treatment was administered once weekly for a maximum of 3 weeks.
Procedure: Aminolevulinic acid photodynamic therapy

ACTIVE_COMPARATOR: Conventional Photodynamic Therapy（C-PDT）
The conventional photodynamic therapy(C-PDT) group underwent narrow-band light-emitting diode (LED) irradiation (630 nm; 100 J/cm2) after applying 20% 5-aminolevulinic acid cream for 3h.A repeat treatment was administered once weekly for a maximum of 3 weeks.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The clearance rate of Genital Warts
Time Frame: one week after the last treatment
The clearance rate of Genital Warts will be measured at one week after the last treatment.
one week after the last treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain assessment
Time Frame: Immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute , and every 10 minute to the end of treatment and 2 hours, 12 hours, 24hours and 48 hours after treatment
The pain will be assessed using Visual Analogue Scale（VAS) 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 min, 3rd min, 5th min, 7th min, 10th min , and every 10 min to the end of treatment and 2nd h, 12th h, 24th h and 48th h after treatment.
Immediately, 1st minute, 3rd minute, 5th minute, 7th minute, 10th minute , and every 10 minute to the end of treatment and 2 hours, 12 hours, 24hours and 48 hours after treatment
The recurrence rates after treatment
Time Frame: 3 months after the last treatment
The recurrence rates will be measured at 3 months after the last treatment.
