About this study

Official title: Efficacy of Oral Melatonin Versus Oral Tranexamic Acid in the Management of Melasma

This study will compare the efficacy of oral melatonin and oral tranexamic acid in treating melasma, with the aim of determining whether melatonin is more effective than tranexamic acid, as measured by MASI scores. Literature suggests melatonin may be more effective due to its antioxidant, anti-inflammatory, and anti-melanogenic properties. The findings will assess whether melatonin provides better efficacy and tolerance compared to tranexamic acid in managing this persistent condition. Efficacy will be assessed by comparing the baseline MASI scores with the scores obtained at six-week and twelve-week follow-up points based on the following cut-offs:

<25% improvement Mild response 25-50% improvement Moderate Response 51-75% improvement Good response >75% improvement Excellent Response

Study period is of 6 months.Total sample size is 180 patents.The sample is divided into two groups, with 80 patients assigned to each treatment.This study hypothesizes that oral melatonin will be more effective than oral tranexamic acid in reducing the severity of melasma, as measured by changes in the Melasma Area and Severity Index.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Melatonin tabletDrug

    Group A will receive oral melatonin 5mg every night for 3 months

  • Tranexamic Acid (TXA)Drug

    Group B will receive oral tranexamic acid 250mg twice daily for 3 months.

Study groups in NCT07169383
Study groupRoleWhat they receive
Group A - Oral melatoninActive comparatorGroup A will receive oral melatonin 5mg daily at night for 3 months after ruling out any contraindications. Melasma Area and severity index will be calculated at day one , 6 weeks and 12 weeks.
Receives: Drug: Melatonin tablet
Group B - Oral tranexamic acidActive comparatorGroup B will receive oral tranexamic acid 250mg twice daily for 3 months after ruling out any contraindications.Melasma area and severity index will than be calculated on day one , 6 weeks and 12 weeks.
Receives: Drug: Tranexamic Acid (TXA)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total participants are 160, 80 in Group A and 80 in Group B

    Group A will receive oral melatonin 5mg HS for 12 weeks and Group B will receive oral tranexamic acid 250 mg BD for 12 weeks and then the improvement will be assessed by calculating MASI score at day 1, 6weeks and 12 weeks.MASI score less than 10 is considered mild , 11-20 is considered moderate and more than 20 is considered Severe Melasma. An improvement greater than 25% in the MASI score will be considered as the threshold for treatment efficacy.

    Measured: 12 weeks

  2. Efficacy of Oral Melatonin VS Oral Tranexamic Acid in the management of Melasma

    As per literature Melatonin may be more effective due to its Antioxidant, Anti-inflammatory and anti-melanogenic properties. The findings will assess whether Melatonin provides better efficacy and tolerance compared to Tranexamic Acid in managing Melasma.An improvement greater than 25% in the MASI score will be considered as the threshold for treatment efficacy.

    Measured: 12 weeks

Individual data sharing
Yes: The plan to share de-identified individual participant data (IPD) from this clinical trial, including the efficacy of oral melatonin versus oral tranexamic acid in managing melasma, with researchers who submit a methodologically sound proposal for secondary analysis. The data shared will include the primary and secondary outcome measures, participant demographics, and other relevant study data. Data will be accessible 12 months after the primary publication of the trial results, via a secure online platform, with a data use agreement. Access will be granted to researchers who provide a detailed proposal and agree to the terms of data sharing, including maintaining participant confidentiality and not attempting to re-identify participants. Requests for data access should be directed to dr.hina567@gmail.com This IPD sharing plan aligns with the ICMJE's expectations for data sharing and transparency in clinical trials.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
