Clinical Trial Summary

The purpose of this study is to determine whether low level laser light therapy is effective in the treatment of acne blemishes.


Description:

Acne is a chronic inflammatory disorder plaguing the sebaceous follicle, and debate still remains over what truly initiates lesion formation. Experts agree that an increase in androgen production plays a significant role in the onset of acne. Androgens promote the increase in size of sebaceous glands and stimulate sebum production. The simple act of sebaceous gland stimulation via androgens could ultimately promote the upregulation of pro-inflammatory cytokines like tumor necrosis factor-α (TNF-α) and interleukin (IL-1α) without propionibacteria even being present. The synthesis of IL-α and other pro-inflammatory cytokines including prostaglandins occurs via the inducible enzyme known as cyclooxygenase-2 (COX-2). Studies analyzing the pathogenesis of mucositis have identified COX-2 as an important contributor to the upregulation of pro-inflammatory cytokines and thus a major contributor to the progression of the disorder itself.

Recent evidence indicates that low-level laser therapy (LLLT) is able to significantly diminish the expression of COX-2, resulting in the reduction of inflammation. The ability to modulate the COX-2 pathways via LLLT is believed to inhibit the production of pro-inflammatory cytokines (i.e. TNF-α and IL- α) present in acne-prone skin.

Intervention

Device:
Erchonia MLS + Erchonia THL
The Erchonia® MLS is administered weekly for 6 continuous weeks at the test site by the study investigator. The Erchonia THL is administered twice daily for 6 continuous weeks (42 days) at home by the subject. Administration of the MLS and the THL occur simultaneously over the 6-week administration phase. The intent is to evaluate the effectiveness of Erchonia MLS & Erchonia THL when administered together, and not to compare Erchonia MLS vs. Erchonia THL

Outcome

Type Measure Description Time frame Safety issue
Primary Grade on the Burton et al. Acne Severity Grade Scale The Burton et al. Acne Severity Grade Scale grades the type of acne lesion from Grade 0: no acne lesions through Grade 1: sub-clinical acne, Grade 2: mild acne, Grade 3: moderate acne; Grade 4: severe acne, to Grade 5: extremely severe acne. The number of participants whose entire face demonstrated an improvement of one or more grades on the Burton et al. Acne Severity Scale at week 6 relative to baseline was calculated. baseline and 6 weeks No
Secondary Change From Baseline in Inflammatory Lesion Count at 6 Weeks The number of pustules, papules and nodules are summed to attain a total inflammatory lesion count. Baseline and 6 weeks No
Secondary Change From Baseline in Non-Inflammatory Lesion Count at 6 Weeks The number of open comedones and closed comedones are summed to attain the total non-inflammatory lesion count. Baseline and 6 weeks No
