Photodynamic Therapy in the Treatment of Acne
A study testing LumaCare LC-122M non-coherent light source in people with Acne Vulgaris, run by University of Michigan.
Trial summary
The purpose of this research project is to study the effect of non-ablative (non-cutting) laser therapy, a technique that uses laser energy to try to improve the appearance of the skin. This type of laser treatment creates changes in a layer of the skin called the dermis without causing an open wound in the skin. Read more about this study

About this study
Official title: Photodynamic Therapy in the Treatment of Acne Vulgaris Using Non-Coherent Red Light (Derm 590)
The purpose of this research project is to study the effect of non-ablative (non-cutting) laser therapy, a technique that uses laser energy to try to improve the appearance of the skin. This type of laser treatment creates changes in a layer of the skin called the dermis without causing an open wound in the skin. The use of non-ablative laser therapy, together with application of a photo-sensitizer (substance that makes the skin more sensitive to light), may improve the appearance of acne. The idea behind the photo-sensitizer is that it is supposed to make the laser more effective than using just the laser alone. It is not yet clear how much improvement can be seen with these treatments or exactly how the skin's response causes these improvements. In this study, we are interested in learning how well such a laser works to improve the symptoms of acne, as well as how much the photo-sensitizer actually enhances the efficacy of the laser.
The photo-sensitizing agent (Levulan Kerastick) and the non-ablative laser (LumaCare LC-122M non-coherent (multiple wavelengths) light source from LumaCare® Medical Products) are both FDA-approved. The Levulan Kerastick is approved for the treatment of another skin disease, not acne.
Read the detailed description
Background
Acne vulgaris remains among the most common cutaneous disorders, impacting the vast majority of people at some point during their lives. It is associated with significant psychosocial morbidity, and there remains the need for efficacious and low risk therapeutic options.
The FDA has approved various lasers and light sources for the treatment of acne. However, few randomized, controlled clinical trials have been performed of these devices. In addition, the use of topical photosensitizers preceding laser or light-therapy for acne has also been examined in a preliminary way with some initial evidence of efficacy. However, these trials have been small with modest numbers of subjects, many focus on back acne, and treatment protocols vary widely and are often poorly controlled. Photodynamic therapy for facial acne is being performed by physicians across the country but little objective data regarding this practice is available.
We have recently conducted a trial of a 1 hour application of a common photosensitizer approved by the FDA for acne phototherapy (Levulan, DUSA pharmaceutical) using a pulsed dye laser therapy (V-Beam laser, Candela Corp., Wayland, MA, 595 nm wavelength) as the activating light source (IRB protocol 2005-0117). Interim results from our study indicate this therapy is effective in a minority of patients. Accumulating published reports data suggests the limited effectiveness of this protocol may be due to inadequate skin penetration of the photosensitizing agent and due to the need for an activating light source with a longer wavelength of light to allow deeper penetration into the skin. We wish to incorporate these findings to design a protocol that should be more effective for treatment of facial acne.
Objectives
We propose to evaluate the efficacy and confirm the safety of an FDA-approved non-coherent light source (LumaCare LC-122M non-coherent light source with LUM-I, fiber optic probe, 610 nm-660 nm output range, LumaCare Medical Products, Newport Beach, Ca) used in conjunction with a topical photosensitizer (Levulan, DUSA pharmaceutical) in the treatment of acne vulgaris. Because one proposed mechanism of action for such treatments includes altered sebaceous gland activity, we also seek to examine the effects of this treatment on cutaneous sebum production.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LumaCare LC-122M non-coherent light sourceDevice
Subjects will receive a series of up to 6 treatment sessions with a treatment interval of from approximately 1 to 4 weeks. In all cases, light treatment parameters will be within the guidelines normally used clinically for red-light non-coherrent light sources, and thus fluences used will not exceed 75 J/cm2.
| Study group | Role | What they receive |
|---|---|---|
| LumaCare LC-122M non-coherent light source | Experimental | Split Face Comparison. One half of subject's face will receive topical photosensitizer applications followed by LumaCare LC-122M non-coherent light source illumination. Subjects will receive a series of up to 6 treatment sessions with a treatment interval of from approximately 1 to 4 weeks. In all cases, light treatment parameters will be within the guidelines normally used clinically for red-light non-coherrent light sources, and thus fluences used will not exceed 75 J/cm2.
The other half of the face will not receive any treatment and will serve as internal control. Receives: Device: LumaCare LC-122M non-coherent light source |
What is being measured
The primary outcome is the main question the study is designed to answer.
Subtypes of acne lesions including papules, pustules, cysts, open comedones, and closed comedones. In addition to lesion counts, overall acne severity will be graded by the investigator using the Leeds acne severity scale.
Measured: Baseline and follow-up evaluations

A study testing LumaCare LC-122M non-coherent light source in people with Acne Vulgaris, run by University of Michigan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 4 May 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Subtypes of acne lesions including papules, pustules, cysts, open comedones, and closed comedones. In addition to lesion counts, overall acne severity will be graded by the investigator using the Leeds acne severity scale. (time frame: Baseline and follow-up evaluations). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 May 2015.
