Study summary

The purpose of this study is to determine whether 5-FU infusion (Microinfusion of Medicine Percutaneously - MMP) is effective for Idiopathic Guttate Hypomelanosis (IGH) repigmentation compared to conventional Microneedling. MMP is a procedure done with tattoo devices using medication in place of ink.

  • Capable of understanding and providing a written
  • Fertile women will have to use a viable method for at least 3 months prior to entry and throughout the entire study

Exclusion criteria

Exclusion Criteria:

  • Pregnancy, intention to become pregnant during the course of the study, less than 3 months after delivery or less than 6 weeks after breastfeeding cessation.
  • Uncontrolled comorbidity or any disease that, in the investigator's opinion, may interfere with the treatment, healing or cure.
  • Present symptoms of hormonal disturbances, as per the investigator's criteria.
  • Constitutional photosensitivity or due to metabolic disfunction, or due to use of external agentes (pharmaco, natural products, etc.) prior to initial treatment or during the study.
  • Use of oral isotretinoin 6 months prior to initial treatment or during the course of the study.
  • Prior treatment in target área 3 months prior to initial treatment or during the course of the study.
  • Adverse reaction to any external agentes (gel, lotions or anesthetic creams) required during the study in case no alternative is available for such agent.
  • History of keloids or other type of hypertrophic scar formation or poor wound healing in a previously injured area of skin.
  • History of collagen disease.
  • Displastic nevus or suspicious carcinogenic lesion in área to be treated.
  • Hemmorragic disorder or under anticoagulant medication, including the use of aspirin not permitting a minimum 10-day suspension prior to each treatment period (in accordance with the criteria of the patient's physician).
  • Skin frailty of sensitivity, favoring hemmorrage.
  • History of immunosuppresion / immunological deficiency disorders (including infection) or use of medication.
  • Participation in a study involving medication or another device three months prior to the study or during enrollment herein.
  • Any condition which, in the investigator's opinion, would jeopardize the study or its participants, such as acute psychiatric disorders, panic syndrome or any aversion to needles or to the procedure.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

  1. Lesions counting of Idiopathic Guttate Hypomelanosis (IGH)

    Two assessors will independently count the number of lesions in the treated skin area

Secondary outcomes

  1. Patient satisfaction assessed by Likert scale

    self-administered

    Time frame: 30 days

  2. Local adverse events

    Frequency of patients presenting at least one local adverse event (ex:intense pain, scars, infection)

    Time frame: 30 days

  3. Systemic adverse events

    Frequency of patients presenting at least one systemic adverse event (anaphylactic reaction)

    Time frame: 24 hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 1, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
