Topical Gentamicin Nonsense Suppression Therapy of EB
Norway4 participantsStarted 2020-12-01
Plain-language summary
The overall purpose of this study is to address whether topical gentamicin therapy is an effective and feasible treatment. Specifically, we will investigate the effect of non-intensive treatment (once daily or every other day) on skin protein expression, as well as quantify the effect on wound healing in patients with EB caused by PSC (part A). Furthermore, we will address in vitro whether gentamicin restores protein expression of genes affected by SSM in fibroblasts derived from skin biopsies obtained from patients with EB caused by SSM (part B). If these in vitro experiments yield positive results, the patients donating the cells will be offered to enter part A of this study. The overall duration of part A in this study is planned to be 18 weeks per patients and consists of a 6 weeks treatment period followed by a 12 week follow up period. Each patient will attend 3 study visits: at week 0, week 6 and week 18. All patients will be included within a time period of 12 months. The overall duration of part B will be up to 8 weeks per patients of which 4-7 weeks are spent to prepare fibroblasts obtained from skin biopsies. Then 5 days of in vitro intervention and subsequent analysis follows. Altogether, the duration of the GENTELBULL study will be 78 weeks or less.

Inclusion criteria
. The patient has EB caused by nonsense mutation
. The patient has a symmetrical distribution of wounds which allows for wounds on one side of the body to serve as control wounds, while study therapy is applied to the other side.
. The patient (if an adult) or parent(s)/guardian(s) is capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
. Women of childbearing potential must use a highly effective contraception method
Exclusion criteria
. Known contact allergy against gentamicin sulfate or other ingredients in the ointment
. Known intolerance to gentamicin sulfate of any sort
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?
