Plain English summary of protocol

Background and study aims
Ocular surface disease (OSD) is a cause of eye discomfort. It is a complex condition that includes severe dry eye disease (DED). Symptoms such as dryness and eye pain can lead to anxiety, and these can affect sight and well-being. Lubricating eye drops are used to relieve symptoms but these need to be applied frequently and their effects can be short-lived. The University of Birmingham has developed a new fluid-gel eyedrop containing blood serum (a standard treatment for severe OSD) which may stay on the eye surface for longer than current lubricating eye drops, thereby providing longer-term relief. Phase I and II trials are done with a small number of people to see if an experimental treatment is safe. The eyedrops are made of products currently in other eyedrop treatments used in clinical practice. The main aim of this trial is to investigate whether the gel-based eyedrop, alone (called FLG-1001) or containing serum (called FLG-SED1) can be applied safely to eyes. Whether the gel-based eyedrops are better at providing patient comfort by improving eye surface health more than the standard treatment, serum in saline (called ATF-Allo-SED in this study), will also be studied.

Who can participate?
Participants aged 16 years old and over with moderate to severe DED who have used or are currently using serum eye drops

What does the study involve?
This trial has two stages. In Stage 1, six DED patients will receive each treatment for one day over three consecutive days. In Stage 2, 30 DED patients will be given (at random) either FLG-1001, FLG-SED-1 or ATF-Allo-SED for 42 days, followed by one extra visit one-week later. Safety will be measured by looking at how the treatments affect the eye surface and patient symptoms using clinical tests, patient diaries and questionnaires. Patients will use their current eye medication alongside the new treatments if needed.

What are the possible benefits and risks of participating?
The possible benefits of participating:
1. The new fluid-gel eye drops may improve DED symptoms
2. Participants may experience longer periods of eye comfort and therefore it may mean they won’t need to use their other treatments as often
3. Participants will be provided with a cool bag to carry their eye drops around and can keep this bag when they finish the trial.

The possible risks of participating:
1. Possible side effects from taking the new fluid-gel eye drops
2. The treatment may not be effective
3. The participant’s DED symptoms may get worse
4. Attending multiple hospital visits to monitor eye health and safety
5. Time taken to complete the tests during the visits
6. Slight discomfort from some of the tests
7. Time taken to complete the questionnaires may be tiring
8. Participants must keep the eye drop cool if they are out for the day, however individual cool bags with ice packs will be supplied to participants for them to use and keep once their involvement in the trial has ended

Where is the study run from?
The trial is run by the University of Birmingham (UK) and will take place in the Birmingham and Midland Eye Centre, City Hospital Birmingham (UK)

When is the study starting and how long is it expected to run for?
December 2022 to December 2027

Who is funding the study?
National Institute for Health and Care Research (NIHR) Invention for Innovation (i4i) Programme (UK) (Award ID: II-LA-1117-20001)

Scientific titleTherapeutic fluid-gels for eye disease: Ocular Surface Disease. A phase I/IIa safety trial evaluating allogeneic donor serum gel in patients with severe ocular surface disease (OPtiCS-OSD)
Study acronymOPtiCS-OSD
Study objectivesTo assess the safety and tolerability of a new fluid-gel eyedrop alone (called FLG-1001) and containing blood serum (called FLG-SED1) in participants with moderate to severe dry eye disease

To assess the effects of a new fluid-gel eyedrop alone (called FLG-1001) and containing blood serum (called FLG-SED1) on the surface of the eye
Ethics approval(s)

Approved 17/08/2023, London - Surrey Borders Research Ethics Committee (Equinox House, City Link, Nottingham, NG2 4LA, United Kingdom; +44 (0)207 104 8057; surreyborders.rec@hra.nhs.uk), ref: 23/LO/0064

Health condition(s) or problem(s) studiedOcular surface disease, dry eye disease
InterventionFor each eye drop of the investigational medicinal product (IMP), one dose is considered to be a single drop to both eyes and, in all stages, participants will continue to use their standard eye treatment as often as required throughout the trial.

In Stage 1, six DED patients will receive each treatment for one day over three consecutive days. On Day 0, one dose of ATF-Allo-SED will be administered in the clinic in the morning, followed by two doses in the clinic in the afternoon, and then four doses administered by the participant at home during the afternoon/evening. On Day 1, FLG-1001 will follow the same dosing pattern as Day 0 first in the clinic and then at home. On Day 2, FLG-SED1 will follow the same dosing pattern as Day 0 and Day 1 in the clinic and then at home. Participants will attend the clinic for a final follow-up visit on Day 3.

In Stage 2, 30 DED patients will be given (at random via an online tool) either FLG-1001, FLG-SED-1 or ATF-Allo-SED (10 participants per trial arm) for a minimum of 6 doses per day for 7 days, then as frequently as required until Day 42 of treatment, followed by one follow-up visit one week later.
