Plain English Summary

Background and study aims
The Light Touch study looks at patients with neovascular age-related macular degeneration (nAMD) who have been receiving regular intravitreal injections and would be eligible to switch to a new agent, faricimab. The usual approach to switching would require an initial 4 injections over 4 months. This study looks at whether starting treatment with fewer drug injections (i.e., a "light touch") can still help patients see well, aiming to make treatment less demanding by reducing the number of doctor visits and injections needed.

Who can participate?
Patients aged 50 years or older with nAMD who have been previously treated with anti-angiogenic treatment (excluding faricimab) and undergone an initial induction phase of three monthly injections

What does the study involve?
The study will compare two treatment regimens of faricimab: the standard induction phase (four initial monthly injections) versus a "light touch" regimen (one initial injection followed by personalized treatment intervals). The total study period is 112 weeks, including a 56-week treatment and follow-up phase for participants.

What are the possible benefits and risks of participating?
Faricimab has been widely used globally and the UK for diabetic macular oedema and nAMD and is EMA and MHRA approved for these indications and NICE recommended for nAMD and diabetic macular oedema (DMO). Cumulative safety data to date does not show an increased risk of any ocular or systemic adverse events with this anti-VEGF agent compared to other similar drugs used for these indications. There is therefore no risk to the use of this drug over and above standard care. Optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) are non-invasive tests that takes images of the inside of the eye. They do not touch the eye, and are painless. There are no known side effects or complications. These are used in standard care so the risks are no greater than standard care.

Where is the study run from?
Moorfields Eye Hospital NHS Foundation Trust (UK)

When is the study starting and how long is it expected to run for?
June 2024 to January 2027

Who is funding the study?

Study typeTreatment
Scientific titleA multicentre randomised controlled clinical trial testing the non-inferiority of a lighter to the standard initial dosing regimen of faricimab in patients with pretreated neovascular age-related macular degeneration
Study acronymLight Touch Study
Study hypothesisFor patients with wet age-related macular degeneration (AMD) that switch to faricimab, it is not known how frequently the injections should be given after switching. This study will determine whether a single treatment (a ‘Light Touch’) at the beginning followed by a personalised treatment interval is as clinically effective as an intensive period of four monthly treatments (an ‘induction phase’) followed by personalised treatment intervals.

The primary objective hypothesises that the intervention “Light Touch” arm will be non-inferior to the standard of care (SoC) "Induction Phase" arm in terms of visual outcome at an average of Week 52 and Week 56.
The secondary objectives of the Light Touch Trial aim to explore additional outcomes beyond comparing change in visual acuity. Specifically, the trial seeks to answer the following questions:
1. Visual acuity improvements: how many patients experience improvements in their vision after switching to faricimab, and how significant are these improvements?
2. Avoiding vision loss: how many patients manage to avoid losing vision during the trial?
3. Vision quality over time: how consistent is the treatment response over time in terms of visual acuity?
4. Eye anatomy changes: what changes occur in the central part of the retina and overall eye anatomy, and how do these changes correlate with treatment?
5. Treatment frequency: how often do patients need injections after switching to faricimab, and can the intervals between treatments be safely extended?
6. Patient experience: what are the patient-reported outcomes regarding their quality of life, burd

Approved 05/09/2024, South Central - Hampshire A Research Ethics Committee (2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 1048135; hampshirea.rec@hra.nhs.uk), ref: 24/SC/0237

ConditionNeovascular age-related macular degeneration
InterventionPatients with nAMD in at least one eye which were previously treated with anti-angiogenic therapy that would not allow injection interval extension will be randomised 1:1 to either: Standard of Care (“Induction Phase”) Arm or the Intervention (“Light Touch”) Arm.
Standard of Care (“Induction Phase”) Arm: An initial induction (also known as loading) phase, a total of 4 intravitreal injections of faricimab 6 milligrams (mg) once every 4 weeks (Q4W) starting from baseline up to and including Week 12.
Treat-and-extend pathway (T&E) from Week 20 to Week 56 (final study visit).

Intervention (“Light Touch”) Arm: One intravitreal injection of faricimab [6 mg, 0.05 mL solution] at baseline. Duration between baseline and subsequent treatment visit will be the number of weeks in pre-switch treatment interval. T&E starting from the second visit (“Light Touch”) and continuing to Week 56 (final study visit). Pre-switch treatment interval is defined as the duration between injections required by the study eye prior to faricimab switch. This is determined by the principal investigator based on the last 3 treatment visits prior to switch and considering non-clinical factors such as clinic cancellations and patient-factors.
