February 7, 2017 updated by: M.B.A. van Doorn, Erasmus Medical Center

Treatment of Port Wine Stains Using Pulsed Dye Laser, Erbium Yag Laser and Topical Sirolimus in an Open Label Pilot Study (POLAR).

The purpose of this study is to improve the therapeutic outcome of laser therapy for port wine stains by using a combination treatment of the pulsed dye laser (PDL), erbium yag laser and topical sirolimus.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

Detailed Description

In the first treatment period all patients will receive a total of five treatments with two week intervals. Every patient will receive the following four treatments (utilizing a template with separate squares of 1cm2): 1) PDL treatment followed by topical sirolimus application after Er:Yag laser ablation of the stratum corneum compared with 2) PDL treatment followed by topical sirolimus application without Er:Yag laser ablation of the stratum corneum, 3) PDL treatment only and 4) sirolimus application only. After the six months follow-up period, during the second treatment period, patients will receive an additional five treatments of the adjacent cosmetic unit of the treated part of the PWS, employing the most successful of the four treatment modalities as evaluated after the first treatment period.

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)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Subject has provided informed consent;
  • Subject is ≥ 18 years of age at time of screening;
  • Subject has an extra-facial homogenous Port Wine Stain (PWS);
  • The PWS is large enough in size to fit one of the templates
  • Subject has not received any laser treatment of the PWS in the last 3 months (in the treatment area);
  • The PWS has a minimal erythema grading score of 3 (on a 4 point scale) in the opinion of the investigator;
  • Screening blood safety values are within normal parameters or regarded as not clinically significant in the opinion of the investigator.

Exclusion Criteria:

  • PWS with a nodular/hypertrophic component in the treatment area;
  • PWS on cosmetically unacceptable locations in the opinion of the investigator;
  • For women: pregnant or breast feeding during the treatment period;
  • Women of child-bearing potential, unless they are using adequate contraceptive measures
  • Subject is known to have immune deficiency, or is immune compromised
  • Known allergy to sirolimus or other constituents of the study medication;
  • Incapacitated subjects;
  • Any medical or psychiatric condition which, in the investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
