Plain-language summary

The objective of the present study was to study the impact of insulin insitu-gel formulation on healing progress after surgical procedures for treatment of dry tympanic membrane perforation for at least three consecutive months. At the beginning, an insulin insitu-gel was prepared from three different polymers compatible with insulin physiochemically and reported to be vain on insulin efficacy or safety. Insulin insitu-gel was prepared using chitosan, polyvinyl alcohol, and Pluronic F127 with glycerol as a penetration enhancer. Selection of an optimized formulation through in situ gel characterization and in vitro drug release kinetics then the formulation was evaluated for healing efficacy on human volunteers in RCT. A randomized controlled clinical study was implemented for clinical evaluation of insitu-gel formulation activity in the Department of Otorhinolaryngology, Minia University Hospital, from January 2025 to March 2026. Perforation healing signs as a primary indicator was followed and reported in three follow-up visits (1 week, 1 month, and 2 months) in addition hearing score pre- and post-surgery as secondary outcomes. Results of a clinical study showed that the healing is significantly superior in the insulin group than in the control group

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?

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?
