Efficacy of Oral Metformin vs Oral Doxycycline in Treating Acne Vulgaris

Pakistan68 participantsStarted 2025-02-15

Plain-language summary

The goal of the clinical trial is to learn if oral metformin works to treat moderate to severe acne vulgaris. Investigators will compare this drug to oral doxycycline to see if this drug works to treat acne. All participants will be divided into two groups. Group A will be given oral Metformin 500 mg to be taken twice daily, while Group B patients will be given oral Doxycycline 100 mg once daily. They will be assessed by the scoring method Total Lesion Count (TLC) and the Global Acne Grading System (GAGS) at each follow-up (i.e., at 0, 8, and 12 weeks). Efficacy will be measured by using the scoring system GAGS, TLC. The final assessment will be done at the 12th-week follow-up. A total of 68 patients fulfilling the inclusion criteria are enrolled in the study. The efficacy of oral metformin vs oral doxycycline will be measured in all selected patients suffering from acne vulgaris by estimating improvement in the total lesion count (TLC) and the Global Acne Grading (GAGS) assessment score at each follow-up.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
