Study Endpoints

Primary Endpoints

Mean change in maximum corneal curvature (Kmax) between the VibeX active treatment group and placebo control group
baseline to 6 months
Mean Change From Baseline in Maximum Keratometry (Kmax)
baseline,12 months

The primary efficacy parameter was corneal curvature, as measured by maximum keratometry (Kmax) in the study eyes. Study success was defined as a difference of ≥1 D in the mean change in Kmax from baseline to 12 months between the CXL group and control group. Keratometry was measured manually and by pentacam.

Frequently asked questions about riboflavin

What is riboflavin used for in keratoconus?

Riboflavin is an investigational small molecule being studied for corneal collagen cross-linking in progressive keratoconus and ectasia. It is developed by Glaukos Corporation (NYSE: GKOS) and is currently in Phase 3 clinical development. Riboflavin is not FDA approved and remains investigational.

How does riboflavin work?

Riboflavin works as a photosensitizer in corneal collagen cross-linking. When activated by ultraviolet light, it induces cross-linking of corneal collagen fibers, which strengthens the cornea. This mechanism is being studied to halt the progression of keratoconus and ectasia.

Who makes riboflavin?

Riboflavin is being developed by Glaukos Corporation, a company traded on the New York Stock Exchange under the ticker symbol GKOS. The company is conducting Phase 3 clinical trials to evaluate riboflavin for the treatment of progressive keratoconus and ectasia.

What phase is riboflavin in?

Riboflavin is in Phase 3 clinical development for the treatment of progressive keratoconus and ectasia. It is an investigational drug and has not been approved by the FDA. Multiple Phase 3 trials have been completed, but the drug remains in clinical development.

What clinical trials is riboflavin in?

Riboflavin has been studied in several completed Phase 3 trials, including NCT00647699 for progressive keratoconus, NCT00674661 for ectasia, and NCT01344187 and NCT01643226 for keratoconus. These trials were conducted in the United States with a total enrollment of 466 patients.

Is riboflavin the same as corneal collagen cross-linking?

Riboflavin is the drug used in corneal collagen cross-linking (CXL) procedures. The clinical trials listed for riboflavin, such as NCT00647699 and NCT00674661, are titled as corneal collagen cross-linking studies, indicating that riboflavin is the active agent in this procedure.
