The Effect of Adjunctive Melatonin With Colistin in Patients With Multidrug-Resistant Gram-Negative Bacterial Infections
70 participantsStarted 2026-03-26
Plain-language summary
This study evaluates whether adding melatonin to standard colistin therapy improves outcomes in patients with multidrug-resistant (MDR) Gram-negative bacterial infections. These infections are difficult to treat and are associated with high morbidity and mortality, particularly in critically ill patients.
Colistin is often used as a last-line antibiotic for these infections; however, its effectiveness may be limited, and it is associated with side effects such as kidney injury. Melatonin, a naturally occurring hormone, has antioxidant, anti-inflammatory, and immune-modulating properties that may enhance the effectiveness of antibiotics and reduce treatment-related complications.
In this randomized, double-blind, placebo-controlled study, adult patients receiving colistin will be assigned to receive either melatonin or a placebo in addition to standard care. The study will assess whether melatonin improves oxidative stress, infection control, and clinical outcomes while maintaining safety.

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?
