Background and study aims
Dry eye disease or dry eye syndrome is a multifactorial and complex disorder of the tears and ocular surface which occurs when the quantity or quality of tears fails to maintain adequate lubrication of the surface of the eye. Dry eye incidence increases with age and prevalence ranges from 5% to 35% of the adult population depending on the definition of dry eye utilised. Dry eye is a frequently encountered ocular morbidity with 25% of patients who visit ophthalmic clinics report symptoms of dry eye. There are multiple therapeutic options available for dry eye, many of which aim to help lubricate the ocular surface and hence reduce the symptoms of dry eye, however not all patients respond favourably to the prescribed treatments.
Hydroxypropyl-Beta-Cyclodextrin is a soluble, benign, safe and well characterised cyclodextrin that is accepted as an approved excipient of drug formulations, including eye drops, across Europe. Current research suggests Hydroxypropyl-Beta-Cyclodextrin is a suitable molecule for treating the symptoms of dry eye, however due to gaps in the literature this hypothesis remains unconfirmed.
This clinical investigation is aiming to establish the safety and performance characteristics of the medical device Hydroxypropyl-Beta-Cyclodextrin 10% w/v Eye Drops (preservative free), indicated for the relief of dry eye sensations.
The development of Hydroxypropyl-Beta-Cyclodextrin 10% w/v as a novel dry eye drop may provide a safe, efficacious and cost-effective alternative treatment for patients suffering from dry eye.
Who can participate?
Healthy volunteers aged over 50 with mild to moderate dry eye.
What does the study involve?
The study involves application of one drop of Hydroxypropyl-Beta-Cyclodextrin 10% w/v eye drops to each eye two or three times daily, or as required over the course of the six month trial. Patients will be requested to complete a daily diary, a questionnaire and to visit to the centres each month where information is collected including but not limited to Schirmer's test, Tear Film Break-up Time and OCT scan.
What are the possible benefits and risks of participating?
Patients mild to moderate dry eye sensations may be alleviated by using Hydroxypropyl-Beta-Cyclodextrin 10% w/v eye drops as part of this study, but this cannot be guaranteed. Patients may experience some side effects from this treatment such as mild eye irritation.
Where is the study run from?

| Intervention | The study is a single arm design, therefore randomisation is not applicable. All participants will be treated with the Hydroxypropyl-Beta-Cyclodextrin 10% w/v Eye Drops, with 1 drop administered to the affected eye twice daily, or whenever required. The total duration of treatment is 6 months. Participants will start treatment at a baseline visit (0 month) at the study centre and participants will visit the study centre at 1, 3 and 6 months (end of treatment). |
