Study summary

This study will evaluate the use of the Lutronic PicoPlus for treatment of dermatological conditions such as unwanted tattoos and benign pigmented lesions.

Read the detailed description

This pilot clinical trial will evaluate the capability of the Lutronic PicoPlus technology to remove unwanted tattoos and benign pigmented lesions. This trial is designed as a multi-center exploratory, open-label clinical trial comparing each subject's condition before and after treatment. Subjects meeting all entrance criteria will be assigned to Group A for treatment of unwanted tattoos and Group B for treatment of unwanted benign pigmented lesions, melasma, or other skin conditions such as skin rejuvenation. Subjects in each treatment group will receive a series of treatments, e.g., 2-5, and will be asked to complete 1 and 3 month follow-up visit(s) following each treatment to assess treatment efficacy and safety. At investigators' discretion, additional follow-up visits, e.g., at 6 months following treatment, may take place to observe the time course of reactions after treatment and/or assess efficacy. Outcome measures include clinician grading and subject satisfaction post-treatment. Pre-treatment study photos will be obtained at baseline; post-treatment study photos will be obtained at each post-treatment follow-up visit.

What researchers measure

Primary outcomes

  1. Investigator's Global Assessment of Improvement

    Overall aesthetic improvement based on completion of the Physician's Global Assessment of Improvement Scale. Physician evaluators will review study photos post-final treatment, and rate the degree of tattoo clearing or reduction in benign pigmentation observed in the subject's treated area using the following definitions: 3 = Very significant or complete clearing (75-100%) 2 = Significant clearing (50-74%) 1 = Moderate clearing (25-49%) 0 = Mild or no clearing (0-24%)

    Time frame: Up to 6 Months following final study treatment

Secondary outcomes

  1. Subject's Global Assessment of Improvement

    Overall aesthetic improvement based on completion of the Subject's Global Assessment of Improvement Scale. Subjects will be asked review study photos post-final treatment, and rate the degree of tattoo clearing or reduction in benign pigmentation observed in the subject's treated area using the following definitions: 3 = Very significant or complete clearing (75-100%) 2 = Significant clearing (50-74%) 1 = Moderate clearing (25-49%) 0 = Mild or no clearing (0-24%)

    Time frame: 1 month, 3 Months, 6 Months (Group A Only) post final treatment

  2. Subject Satisfaction

    Following the final study treatment, subjects will be asked to rate their level of satisfaction with the laser treatment outcome and the overall laser treatment procedure, using the Subject Satisfaction Assessment Scale and the following definitions: 2 = Extremely Satisfied 1 = Satisfied 0 = Neutral (-1) = Unsatisfied (-2) = Extremely Unsatisfied

    Time frame: 1 month, 3 Months, 6 Months (Group A Only) post final treatment

Other outcomes

  1. Blinded Reviewer's Global Assessment of Improvement

    Three blinded experienced, non-treating clinicians will independently evaluate pre- and post-treatment photos of each subject, presented randomly. Each reviewer will be asked to determine the temporal order (before and after) of each photo pair, and then rate the degree of tattoo clearing or reduction in benign pigmentation in the post-treatment photo using the following scale: 3 = Very significant or complete clearing (75-100%) 2 = Significant clearing (50-74%) 1 = Moderate clearing (25-49%) 0 = Mild or no clearing (0-24%)

    Time frame: 3-month (Group B), 6 months (Group A) Post Final treatment

  2. Melasma Area Severity Index (MASI)

    Three blinded experienced, non-treating clinicians will independently evaluate pre- and post-treatment photos of each subject, presented randomly, using the MASI. Each of four regions (forehead, right malar region, left malar region and chin) will be assessed based on three variables: percentage of the total area involved (A), darkness (D), and homogeneity (H).

    Time frame: 3 Months (Group B), 6 Months (Group A) post final treatment

Limitations and caveats
Early termination of the study led to reduced endpoint evaluation and consistent timing for all the endpoints which were analyzed. It also means that full treatment regimen to fully observe the treatment effectiveness and safety could not be fully completed.
