Primary Objective:

To assess the efficacy of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on overall corneal thickness via AS-OCT in patients with stage 3 neurotrophic keratitis with respect to change from baseline at weeks 4, 8, and 16.

Secondary Objectives:

To assess the effects of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal stromal thickness via AS-OCT in patients with stage 3 neurotrophic keratitis with respect to change from baseline at weeks 4, 8, and 16.

To assess the effects of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal stromal reflectivity via AS-OCT in patients with stage 3 neurotrophic keratitis with respect to change from baseline at weeks 4, 8, and 16.

To assess the effects of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal sensitivity via Cochet-Bonnet aesthesiometer in the center of the lesion with respect to change from baseline at weeks 4, 8, and 16.

Read the detailed description

This clinical study is a prospective, open-label, interventional, multicenter study of 8 weeks of treatment with 8 weeks of follow-up after treatment to evaluate the efficacy of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal thickness and stromal clarity via AS-OCT in patients with stage 3 neurotrophic keratitis.

The study will be a total of 16 weeks in duration: an optional screening period of up to 2 weeks, followed by an 8-week treatment period and an 8-week follow-up period. At Visit 1.2 (Baseline and Study Product Dispense, Day -1), patients meeting the entry criteria for this study will be assigned to treatment with cenegermin-bkbj (20 mcg/mL) ophthalmic solution (which will be known as Study Product) beginning the morning following that visit, or Day 0.

After completion of the Treatment Period, all patients who do not meet deterioration or no improvement criteria will continue to be followed for an additional 8-week Follow-Up Period.

At any time during the study, patients may be seen for additional unscheduled visits as deemed necessary by the Investigator.

For patients who are prematurely discontinued from the study at any point, an exit examination should be completed which represents the next data collection visit in the study timeline. Once exited, the Investigator should direct patients for further treatment as appropriate. Patients in this study who are prematurely discontinued before completion of 8 weeks of treatment with cenegermin-bkbj (20 mcg/mL) ophthalmic solution will continue to be followed throughout the remainder of the study period, if able.

To minimize risk of bias, all images will be assessed at an independent central reading center (CRC). The study site will acquire the images and perform a quality check; however, no analysis is required to be conducted by the Investigator on site.

Study groupRoleWhat they receive
Cenegermin-bkbjExperimentalcenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal thickness administered as topical drops via anterior segment optical coherence tomography (AS-OCT), where cenergermin-bkbj stands for Topical Recombinant Human Nerve Growth Factor (rhNGF). Cenegermin-bkbj, the active ingredient of OXERVATE® 0.002% (20 mcg/mL) cenegermin-bkbj ophthalmic solution, is structurally identical to the human nerve growth factor (NGF) protein made in ocular tissues.

What is being measured

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

  1. Change in overall corneal thickness via AS-OCT from baseline to weeks 4, 8, and 16.

    The changes from baseline in corneal thickness via AS-OCT from baseline to weeks 4, 8, and 16 will be analyzed by means of an adjusted longitudinal regression model

    Measured: weeks 4, 8, and 16.

Secondary outcomes (4)
  1. Change in corneal stromal thickness via AS-OCT from baseline to weeks 4, 8, and 16.

    the effects of cenegermin-bkbj (20 mcg/mL) ophthalmic solution on corneal stromal thickness via AS-OCT will be assessed in patients with stage 3 neurotrophic keratitis

    Measured: weeks 4, 8, and 16

  2. Change in stromal reflectivity via AS-OCT from baseline to weeks 4, 8, and 16

    corneal stromal reflectivity via AS-OCT in patients with stage 3 neurotrophic keratitis will be assessed

    Measured: weeks 4, 8, and 16

  3. Change in corneal sensitivity within lesion area via Cochet-Bonnet from baseline to weeks 4, 8, and 16.

    Change in corneal sensitivity within lesion area via Cochet-Bonnet aesthesiometer will be assessed

    Measured: weeks 4, 8, and 16

  4. Frequency and severity of TEAE throughout the study until the FU week 16 assessment (Day 112 +/- 3)

    AEs will be coded by preferred term and system organ class by using the latest version of the Medical Dictionary for Regulatory Activities AEs will be summarized overall, by severity, and by relationship to study product. Serious AEs and AEs leading to discontinuation of study product will also be summarized.

    Measured: Throughout the study until Day 112 +/- 3

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing OXERVATE® 0.002% in people with Neurotrophic Keratitis and Neurotrophic Keratopathy, run by Dompé Farmaceutici S.p.A.

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 7 inclusion and 19 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: withdrawn, as of the sponsor's last update on 2 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in overall corneal thickness via AS-OCT from baseline to weeks 4, 8, and 16. (time frame: weeks 4, 8, and 16.). 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 2 Dec 2024.
