Study summary

Title: Intravitreal faricimab in diabetic macular edema with limited response to aflibercept

Purpose: The purpose of this investigator initiated study is to identify the effects of intravitreal faricimab on recurrence-free treatment intervals and morphological features in diabetic macular edema (DME) in which the Optical coherence tomography (OCT) guided treatment interval failed to be extended to 6 weeks intervals in a treat and extend regimen using aflibercept.

Objectives: The primary objective is to evaluate the proportion of patients with an increased maximum treatment interval with intravitreal faricimab (compared to previous 4-week interval under aflibercept) in an OCT guided treat and extend regimen at month 6 and 12. (for further outcome measures see section Objectives)

Title: Intravitreal faricimab in diabetic macular edema with limited response to aflibercept

Study purpose: The purpose of this investigator initiated study is to identify the effects of intravitreal faricimab on recurrence-free treatment intervals and morphological features in diabetic macular edema (DME) in which the Optical coherence tomography (OCT) guided treatment interval failed to be extended to 6 weeks intervals in a treat and extend regimen using aflibercept.

Objectives: The primary objective is to evaluate the proportion of patients with an increased maximum treatment interval with intravitreal faricimab (compared to previous 4-week interval under aflibercept) in an OCT guided treat and extend regimen at month 6 and 12.

The secondary objectives are:

  • The mean maximum treatment interval with intravitreal faricimab at month 6 and 12.
  • The number of treatments applied during the 12 months study period.
  • The mean change in BCVA (Best Corrected Visual Acuity) from baseline (=switch to faricimab) to month 6 and 12.
  • To compare the mean BCVA at baseline (=switch to faricimab) and month 6/12 in patients with extended treatment intervals under faricimab.
  • The mean change in CS (Contrast Sensitivity) from baseline (=switch to faricimab) to month 6 and 12.
  • The mean change in AllEye index (metamorphopsia index) from baseline (=switch to faricimab) to month 6 and 12.
  • The mean change in central retinal thickness as measured in the central ETDRS ( Early Treatment Diabetic Retinopathy Study) subfield from baseline (=switch to faricimab) to month 6 and 12.
  • To compare the incidence of qualitative OCT features like intraretinal fluid, subretinal fluid, and hyperreflective foci between baseline (=switch to faricimab) and month 6 and 12.
  • Percentage of patients achieving a dry retina at month 6 and 12.
  • The mean changes in FAZ (foveal avascular zone) area and vessel density as measured by OCT-Angiography (OCTA) from baseline (=switch to faricimab) to month 6 and 12.
  • The change in quality of life (VFQ-25 scores) from baseline to 6 and 12 months.
  • To evaluate the safety and tolerability of up to 4weekly dosing of faricimab in DME by determining the rates of adverse events and serious adverse events at 6 and 12 month

Population: This outpatient study population will consist of a representative group of male and female patients ≥ 18 years of age suffering from DME with a treatment interval of 4 weeks under aflibercept. All patients are pre-treated with intravitreal aflibercept for at least 6 months in a treat and extend regimen. For In-/Exclusion criteria see section Eligibility.

Sample size will be 30. This is a pilot study investigating faricimab in pretreated aflibercept high demanders with DME using a real-life like treat and extend schema. So far this population has not been investigated with faricimab. In the context of recent market approval in Switzerland a timely start of the study to generate prospective data in this population with the highest treatment burden is recommended.

Measurements and Procedures:

All consenting, enrolled patients will receive an intravitreal injection of faricimab 6 mg at baseline (week 0), at week 4, 8, 12 (=4x loading) and each of the following treat and extend visits. From visit 4 (week 12) onwards extension of treatment intervals is possible 2-week-stepwise, e.g. 4, 6, 8 weeks etc. Starting at week 12 at each visit the next treat and extend interval (and so the exact date of the next visit) will be defined depending on the following criteria:

  1. Presence of any DME activity including:

    • sub- and/or intraretinal fluid within the central ETDRS (Early Treatment Diabetic Retinopathy Study) subfield and/or ETDRS inner ring

    → new treatment interval = last treatment interval reduced by 2 weeks but minimum interval is 4 weeks, which means 4 weeks interval stays at 4 weeks, 6 weeks interval is reduced to 4 weeks etc

  2. No signs of DME activity:

    → new treatment interval = last treatment interval plus 2 weeks

  3. If there was 2 times a recurrence at a certain interval, in this patient the treatment interval stays at the 2 weeks lower interval.

Efficacy assessment at 3 months is within loading phase; for efficacy assessments after 6, 9 and 12 months a treat and extend visit which takes place within 2 weeks before/after (meaning 24±2 weeks, 36±2 weeks and 48±2 weeks, respectively) can replace an extra assessment visit as far as the required examinations are performed.

Efficacy assessments:

  • Spectral-domain Optical coherence tomography (SD-OCT) at each study visit from baseline through month 12.
  • Best corrected visual acuity (BCVA) measurements using the ETDRS-testing charts at a testing distance of 4m following ETDRS (Early Treatment Diabetic Retinopathy Study) refraction protocol at baseline, week 4, month 3, 6, 9 and 12.
  • Contrast sensitivity measurement at baseline, week 4, month 3, 6, 9, 12.
  • AllEye metamorphopsia measurement (self-test) at baseline and at each study visit from baseline through month 12.
  • Swept-source OCT-Angiography at baseline, month 3, 6, 9, 12.
  • Fluorescein angiography (FA) at baseline and month 12.
  • Quality of life questionnaires VFQ-25 at baseline and month 6 and 12.

Other assessments:

  • Ophthalmic examinations (slit lamp exam, fundus ophthalmo-scopy, Intraocular pressure (IOP) by applanation tonometry)
  • Color fundus photography at baseline and month 12.
  • Vital signs: heart rate (HR), blood pressure (BP)
  • Adverse events (ocular and non-ocular)

Study Product / Intervention:

This study will include the following drug:

Investigational therapy

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 9, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
