NCT05241145

Brief Summary

We investigated the use of a copper sulfate eye drop (IVMED-80) for the treatment of keratoconus. Preliminary laboratory data shows that the addition of copper sulfate increase crosslinking of the structural proteins of the cornea thereby halting the progressing corneal thinning and bulging seen in keratoconus. We conducted a Phase 1/2a study to evaluate the safety and preliminary efficacy of a 6-week and a 16-week regimen using IVMED-80 and studied its impact on ocular safety and the change/progression in patients' vision and clinical measurements.

Outcome Measures

Primary Outcomes (3)

  • Mean Maximum Central Keratometry (Kmax)

    Change in maximum central keratometry after the assigned treatment was compared with baseline measures. This will be evaluated with and without z-score imputation. It will also be evaluated with a linear mixed effects model.

    26 weeks

  • Number of Treatment-Emergent Adverse Events

    Treatment-emergent adverse events (TEAEs) were defined as events requiring additional treatments or cessation of the study article for which the date of onset was on or after the date of first dose of double-masked study drug at Day 0.

    26 Weeks

  • Mean Best Corrected Distance Visual Acuity (BCVA)

    Change in BCVA after the assigned treatment was compared with baseline measures.

    26 Weeks

Secondary Outcomes (14)

  • Mean Corneal Astigmatism

    26 Weeks

  • Mean Central Keratometry (Kmean)

    26 Weeks

  • Mean Posterior Maximum Corneal Elevation

    26 Weeks

  • Mean Endothelial Cell Count (ECC)

    26 Weeks

  • Percentage of patients with discomfort and redness upon instillation

    26 Weeks

  • +9 more secondary outcomes

Study Arms (3)

IVMED-6Wk

EXPERIMENTAL

In Group 1 (IVMED-6Wk), patients instilled IVMED-80 eye drops into their study eye twice a day for 6 weeks and were followed for an additional 20 weeks without treatment (total 26 weeks)

Drug: IVMED-80

IVMED-16Wk

EXPERIMENTAL

In Group 2 (IVMED-16Wk), patients instilled IVMED-80 eye drops into their study eye twice a day for 16 weeks and were followed for an additional 10 weeks without treatment (total 26 weeks)

Drug: IVMED-80

Placebo

PLACEBO COMPARATOR

In Group 3 (Placebo), patients instilled IVMED-80 vehicle solution eye drops into their study eye twice a day for 16 weeks and were followed for an additional 10 weeks without treatment (total 26 weeks)

Other: Placebo

Interventions

Good Manufacturing Practices-grade copper (ІІ) sulfate pentahydrate (CuSO4 #5H2O MW 249.69) was dissolved in a vehicle solution comprised of a balanced salt solution (BSS) with osmolality of approximately 500 mOsm/L. Copper sulfate was concentrated to 0.15 mg/mL. The drops were manufactured on prior to the study at a compounding pharmacy in Salt Lake City, Utah.

This was identical to the IVMED-80 product, but without the active ingredient, copper sulfate.

Masking Details
The investigational products, IVMED-80 or Placebo (IVMED-80 vehicle solution) eye drops, were masked to all sponsor and site personnel with the exception of those directly involved with the production, labeling and shipping of product to the study sites. During the study, the identity of the test articles and randomization were not revealed. An unmasked study coordinator managed test article receipt, dispensing and inventory at the study site. Investigators who interacted with study patients to assess safety and efficacy were masked as to the identity of the test articles and treatment group assignments.
