What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study tests whether a targeted laser treatment, called photothermal therapy, can slow the progression of intermediate age-related macular degeneration (AMD). About 240 people aged 60–90 with intermediate AMD will receive either the laser or a sham procedure. The main goal is to see if the treatment preserves the health of light-sensing cells in the eye over 12 months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
photothermal therapy (laser treatment)
What this could lead to
If successful, this laser treatment could slow the progression of intermediate AMD and help preserve vision longer.
What could go wrong
This is an early-stage trial with no phase assigned, so results are uncertain. The treatment may not slow vision loss or could cause side effects.

Key Inclusion Criteria: * Male, female, or diverse * Age of 60 to 90 years old * Clinically confirmed intermediate AMD (iAMD, AREDS category 3) with the presence of: * At least 3 large drusen (diameter \> 125 μm) within the inner ring of 3mm diameter of the ETDRS Grid centered on the fovea (with or without reticular pseudodrusen (RPE)) * combined with at least 1 of the following other signs: * Incomplete RPE and outer retinal atrophy (i-RORA) outside central 1mm ring and/or * Hyperreflective foci (HRF) adjacent to drusen (within 3 mm) * Best corrected visual acuity between 65 and 87 letters * Clear optic media * Ability to communicate clearly and to understand and comply with the nature and requirements of the study * Ability to provide written informed consent in accordance with institutional, local and national regulatory guidelines * Willing to participate Exclusion Criteria: * Presence of late-stage AMD, neovascular (nAMD, active or fibrotic) or geographic atrophy (GA) * Maculopathies showing only pseudodrusen * Any systemic medication known to be toxic to the lens, retina or optic nerve * Any intraocular surgery within 6 months prior to study inclusion (except uncomplicated cataract surgery \> 3 months) * Any previous thermal laser treatment in the macula * History of vitrectomy, filter surgery, corneal transplantation or retinal detachment * Previous therapeutic radiotherapy in the eye region * Pregnant or breast-feeding patients * Participation in an investigational drug, biologic or device study within 6 months prior to study entry (Note: observational clinical studies involving only over-the-counter vitamins, supplements or diets are not excluded) * Expected participation in an investigational drug, biologic or device study during the duration of this clinical investigation except clinical investigations for diagnostic purposes where examinations are not influencing the outcome of the current clinical investigation. Mandatory for participation in this additional clinical investigation is prior approval from the sponsor of this clinical investigation in writing * A serious medical condition that prevents the patient from performing study activities (including cardiac, hepatic, renal, respiratory, endocrinological, neurological or haematological conditions) or, in the opinion of the investigator, is likely to require surgery or hospitalization (at any time during his/her participation on this clinical investigation) * Known allergy to any ingredient required (for dilation of the pupil, if no alternative agent may be applied) or any contraindication to be treated with Navilas® Laser System 577SL * If, in the opinion of the investigator, it is unlikely that the study protocol will be followed If only one eye is eligible for inclusion, none of the following criteria must be present in the fellow eye in order to allow inclusion of the study eye: * Presence of late-stage AMD in need of therapy * Presence of neovascular AMD (nAMD) in need of therapy * Presence of geographic atrophy (GA) in need of therapy (e.g. complement-inhibitors) * All the non-AMD eye diseases mentioned for the study eye as exclusion criteria * Previous therapeutic radiotherapy in the fellow eye region
