Trial summary

Patients treated with BRAF/MEK inhibitor combinations for malignant melanoma may develop retinal changes known as MEK inhibitor-associated retinopathy (MEKAR). These changes can affect the structure and function of the retina and may cause visual symptoms. Read more about this study

About this study

Official title: Structural and Functional Retinal Alterations in Patients Under Treatment With BRAF/MEK Inhibitors

Patients treated with BRAF/MEK inhibitor combinations for malignant melanoma may develop retinal changes known as MEK inhibitor-associated retinopathy (MEKAR). These changes can affect the structure and function of the retina and may cause visual symptoms.

This prospective interventional study evaluates structural and functional retinal alterations in patients receiving BRAF/MEK inhibitor therapy. The study aims to determine how often MEKAR occurs, describe its clinical characteristics and course, compare its incidence between different BRAF/MEK inhibitor combinations, and assess possible long-term retinal changes after treatment discontinuation.

Participants undergo structured ophthalmologic examinations, including visual acuity testing, retinal imaging, and functional retinal testing before treatment, two weeks after treatment initiation, during therapy if visual symptoms occur, and, when indicated, after treatment completion.

Read the detailed description

BRAF/MEK inhibitor combinations are commonly used in the treatment of malignant melanoma, including adjuvant and metastatic settings. During therapy, some patients develop retinal structural and functional alterations referred to as MEK inhibitor-associated retinopathy (MEKAR).

This study is designed as a prospective, longitudinal, interventional clinical study conducted at the Institute of Oncology Ljubljana. All eligible adult patients with histologically confirmed malignant melanoma who initiate treatment with a BRAF/MEK inhibitor combination (dabrafenib/trametinib or vemurafenib/cobimetinib) are invited to participate.

Participants undergo standardized ophthalmologic evaluations before initiation of therapy, two weeks after therapy initiation, and during treatment if visual symptoms occur. When MEKAR is diagnosed, follow-up examinations are performed at least six months after completion of therapy.

The ophthalmologic assessment includes best-corrected visual acuity measurement, contrast sensitivity testing, slit-lamp examination after pharmacologic dilation, retinal imaging using optical coherence tomography (OCT), infrared and autofluorescence imaging, microperimetry, and electrooculography. In patients receiving adjuvant therapy who develop MEKAR involving the fovea, multifocal electroretinography is additionally performed at diagnosis and repeated after treatment completion.

The study evaluates the incidence of MEKAR, changes in visual function, structural retinal alterations, differences between BRAF/MEK inhibitor combinations, and potential long-term retinal outcomes after therapy discontinuation.

    Participants treated with BRAF/MEK inhibitor combinations undergo ophthalmologic evaluation and retinal functional testing, including best-corrected visual acuity assessment, contrast sensitivity testing, slit-lamp examination, retinal imaging (OCT, infrared imaging, autofluorescence imaging), microperimetry, and electrophysiological testing (electrooculography and multifocal electroretinography when indicated) to detect MEK inhibitor-associated retinopathy (MEKAR) and assess retinal structural and functional alterations during and after therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of MEK Inhibitor-Associated Retinopathy (MEKAR)

    Incidence of MEK inhibitor-associated retinopathy (MEKAR), defined as the proportion of participants who develop MEKAR during BRAF/MEK inhibitor therapy based on predefined clinical criteria and optical coherence tomography (OCT) findings.

    Measured: Baseline (Day 0) through end of treatment (up to 14 months)

Secondary outcomes (2)
  1. Retinal Structural Changes Assessed by Optical Coherence Tomography (OCT)

    Retinal structural alterations assessed by optical coherence tomography (OCT), including presence of neurosensory retinal detachment and other MEKAR-related changes.

    Measured: Baseline (Day 0); Week 2; and up to 14 months

  2. Change in Best-Corrected Visual Acuity (BCVA)

    Change in best-corrected visual acuity (BCVA) measured during ophthalmologic examinations to assess visual function during BRAF/MEK inhibitor therapy.

    Measured: Baseline (Day 0); Week 2; and up to 14 months

Questions about this trial

What is this clinical trial studying?

A study testing Ophthalmologic Retinal Monitoring During BRAF/MEK Inhibitor Therapy in people with Malignant Melanoma and MEK Inhibitor-Associated Retinopathy, run by Institute of Oncology Ljubljana at 1 site in Slovenia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of MEK Inhibitor-Associated Retinopathy (MEKAR) (time frame: Baseline (Day 0) through end of treatment (up to 14 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Feb 2026.
