Efficacy of a Timolol Nasal Spray as a Treatment for Epistaxis in Hereditary Hemorrhagic Telangiectasia (HHT) - (TEMPO)

Plain-language summary
Timolol is a nonselective β-blocker commonly used in the treatment of glaucoma. Recently it has been used topically for the treatment of superficial hemangiomas. Because of its potential mechanism of action, it is possible that timolol could also be useful for the treatment of epistaxis in Hereditary Hemorrhagic Telangiectasia (HHT). Moreover a case was reported in 2012 showing an improvement of nosebleeds with the use of topical nasal timolol. The aim of the study is to evaluate timolol nasal spray efficacy in HHT.
The main objective of this trial is to evaluate, 3 months after the end of the treatment, the efficacy on the duration of nosebleeds of a 4 weeks timolol intranasal treatment in HHT patients with nosebleeds (\>20 min/month). Secondary objectives are to evaluate the tolerance, the efficacy at 6 months after the end of the treatment, and the efficacy on anemia and on clinical parameters (nosebleeds, quality of life and blood transfusions).
This is a prospective double blind phase II study, randomized versus placebo using an allocation ratio of 1:1. A total of 58 patients will be included. The product (solution with timolol at 0.5% or placebo) is self-administered by the patient with a posology of one spray (50 µL) in each nostril twice a day for 28 consecutive days.

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