An 8-week Study to Evaluate Safety and Efficacy of NGF Eye Drops Solution Versus Vehicle in Patients With Dry Eye

January 16, 2019 updated by: Dompé Farmaceutici S.p.A

An 8-week, Phase II, Single-center, Randomized, Double-masked, Vehicle-controlled, Parallel-group Study With 4 Weeks of Follow-up to Evaluate Safety and Efficacy of rhNGF Eye Drops Solution vs Vehicle in Patients With Dry Eye

The primary objective of this study was to assess the efficacy and safety of rhNGF when administered as eye drops to patients with dry eye

The secondary objectives of this study were:

  • To assess change from baseline in Symptom Assessment In Dry Eye (SANDE) scores (without imputation), corneal and conjunctival staining according to National Eye Institute (NEI) scale, and in Tear Film Break-up Time (TFBUT) and Schirmer test I, following 4 and 8 weeks of treatment.
  • To assess change in levels of inflammatory biomarker matrix metallopeptidase 9 (MMP-9) in tears following 8 weeks of treatment.
  • To assess the incidence and frequency of treatment-emergent adverse events (TEAEs) following 8 weeks of treatment.

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 proposed phase II study is a single-center, randomized, double-masked, parallel-arm, vehicle-controlled trial, designed to evaluate the safety and efficacy of Recombinant Human Nerve Growth Factor (rhNGF) eye drops at 20 μg/ml concentration administered six times daily for 8 weeks in patients with dry eye. After confirmation of inclusion and exclusion criteria all eligible patients will be randomized at 2:1 ratio to rhNGF or vehicle control treatment with 8 weeks of study treatments administration with 4 weeks Follow-up.

What is the study measuring?

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
Symptom Assessment in Dry Eye (SANDE) Scores
Time Frame: week 8

Change from baseline with Last Observation Carried Forward (LOCF) imputation. LOCF is a method of imputing missing data in longitudinal studies and tests for difference in mean rates of change in controlled repeated measurements designs with dropouts.

The SANDE score is calculated by taking the square root of the product of the frequency of symptoms score and the severity of symptoms score. The SANDE scale ranges from 0 to 100 with 100 being the maximal amount of dry eye symptoms and 0 being the minimal amount of dry eye symptoms.
week 8

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
SANDE Scores
Time Frame: Week 4, week 8, week 12

Change from baseline with Last Observation Carried Forward (LOCF) imputation. LOCF is a method of imputing missing data in longitudinal studies and tests for difference in mean rates of change in controlled repeated measurements designs with dropouts.

The SANDE score is calculated by taking the square root of the product of the frequency of symptoms score and the severity of symptoms score. The SANDE scale ranges from 0 to 100 with 100 being the maximal amount of dry eye symptoms and 0 being the minimal amount of dry eye symptoms.
Week 4, week 8, week 12
Cornea Vital Staining
Time Frame: week 4, week 8, week 12

Changes from baseline on National Eye Institute (NEI) scale. The NEI/Industry Workshop guidelines were used for grading the scale of corneal and conjunctival damage. The cornea was divided into five sectors (central, superior, inferior, nasal and temporal), each of which was scored on a scale of 0-3, with a maximal total corneal staining score of 15.

Both nasally and temporally, the conjunctiva was divided into a superior paralimbal area, an inferior paralimbal area, and a peripheral area with a grading scale of 0-3 and with a maximal total score of 9 for the nasal and temporal conjunctiva (overall the total score ranged from 0-18).

Briefly, grade 0 reflected normal/healthy situation, whereas grade 3 reflected a severe damage in the considered sector.
week 4, week 8, week 12
Conjunctival Vital Staining
Time Frame: week 4, week 8, week 12

Changes from baseline on National Eye Institute (NEI) scale. The NEI/Industry Workshop guidelines were used for grading the scale of corneal and conjunctival damage. The cornea was divided into five sectors (central, superior, inferior, nasal and temporal), each of which was scored on a scale of 0-3, with a maximal total corneal staining score of 15.

Both nasally and temporally, the conjunctiva was divided into a superior paralimbal area, an inferior paralimbal area, and a peripheral area with a grading scale of 0-3 and with a maximal total score of 9 for the nasal and temporal conjunctiva (overall the total score ranged from 0-18).

Briefly, grade 0 reflected normal/healthy situation, whereas grade 3 reflected a severe damage in the considered sector.
week 4, week 8, week 12
Change in Tear Film Break-up Time (TFBUT)
Time Frame: week 4, week 8, week 12
TFBUT was measured by determining the time to tear break-up. The TFBUT was performed after instillation of 5 μL of 2% preservative-free sodium fluorescein solution into the inferior conjunctival cul-de-sac of each eye. The patient was instructed to blink several times to thoroughly mix the fluorescein with the tear film.
week 4, week 8, week 12
Change From Baseline in Wetting Distance
Time Frame: week 8
The Schirmer test without anesthesia was performed to measure aqueous tear secretion prior to the instillation of any dilating or eye drops
week 8
