Optimizing the Treatment Strategy for Age-related Macular Degeneration (OnP2)

June 4, 2025 updated by: St. Olavs Hospital

A Randomised Controlled Trial Testing the Efficacy of the Treatment Strategy Observe-and-Plan Against Standard Treat-and-Extend in a Population of Newly Referred Patients With Age-related Macular Degeneration.

The purpose of this study is to compare two different treatment protocols for wet macular degeneration; the new protocol called "Observe and Plan" against the current standard protocol "Treat and Extend". Studies suggest that patients achieve equally good visual acuity with fewer controls and that they are more satisfied with the new protocol.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of the study is to test a new treatment protocol for wet macular degeneration, called "Observe and Plan", against today's standard protocol "Treat and Extend". Studies suggest that the individual treatment interval can be achieved earlier with "Observe-and-Plan" and that a proportion of patients do not need more than 3 injections, ie the loading dose. The other advantages seem to be that patients achieve good visual acuity with fewer controls and are more satisfied with the new protocol, which will be beneficial to both patients and health care. To our knowledge, no randomized controlled trial has tested this before.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • diagnosed age-related macular degeneration according to criteria.
  • new diagnose of active CNV verified with OCTA or FA / ICGA.
  • BCVA ≥ 20/200 measured with ETDRS visual acuity chart
  • written informed consent

Exclusion Criteria:

  • Eyes formerly treated with anti-VEGF, photodynamic therapy, radiation therapy, transpupillary thermotherapy or focal laser photocoagulation involving the macular area.
  • Geographic atrophy and subretinal fibrosis affecting the patient's visual acuity.
  • Any other ongoing eye disease that influences patient's visual acuity, such as glaucoma with central vision loss, proliferative diabetic retinopathy, diabetic macular edema or chronic uveitis.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Observe-and-Plan
Patients will follow the same protocol as described by dr. Mantel et al. (2014) in the first Observe-and-Plan study conducted in Lausanne.
Other: Observe and Plan
First the individual interval between the injections of anti-VEGF (vascular endothelial growth factor) is established by observing the time from the loading dose to recurrence of the disease. The patient will come to control every four weeks to establish this interval. Second, the patient will receive injections at intervals that are two weeks shorter than the observed period. 2-3 injections are given before the next control. The control should be no later than six months ahead.
Active Comparator: Treat-and-Extend
Patients will follow the standard treatment protocol for Treat-and-Extend, used for several years in the participating clinics.
Other: Treat-and-Extend

At the first control 4 weeks after the loading dose, the ophthalmologist assesses whether the macula is still wet or whether the macula is dry. In case of wet macula, the patient receives a new injection on the same day and a new control in 4 weeks. If the macula is dry, the patient will return in 2 weeks for the next injection, ie the injection interval is extended from 4 to 6 weeks.

Patients will be controlled every time they are to receive an intravitreal injection. If the macula is dry, the injection interval will be extended by 2 weeks and if the macula is wet the interval is shortened by 2 weeks. The shortest interval will be 4 weeks.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Visual acuity
Time Frame: 1 year
Number of letters read at the ETDRS chart will be tested for each eye starting with a test distance of 2 meter, after correction of the refraction. A standardized testing protocol will be used both for refraction and the visual acuity test.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient satisfaction assessed by NEI-VFQ-25
Time Frame: 1 year
National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). The VFQ-25 is a reliable and valid 25-item version of the 51-item National Eye Institute Visual Function Questionnaire (NEI-VFQ). It is especially useful in settings such as clinical trials, where interview length is a critical consideration.
