About this study
This study is being conducted to evaluate the safety and effectiveness of using the PXL Platinum 330 System with riboflavin solution for performing corneal collagen crosslinking (CXL) for the treatment of refractory corneal ulcers. The PXL Platinum 330 System is a combination product consisting of an ultraviolet-A (UV-A) 365 nm wavelength light source (PXL Platinum 330 Illumination System) and riboflavin (Peschke Riboflavin 0.25% Transepithelial Solution) administered in conjunction with the UV-A light as a photosensitizer.
The PXL Platinum 330 System is intended to induce corneal collagen CXL to improve the biomechanical properties of the cornea by strengthening the corneal tissue in the anterior stroma. Corneal collagen CXL is performed by pretreating the cornea with riboflavin 0.25% ophthalmic solution beginning 40 min before UV-A light exposure to saturate the corneal tissue with the riboflavin photosensitizer. The cornea is then irradiated with UV-A light (365 nm) at an irradiance of 18 mW/cm2 (5 seconds on, 5 seconds off) for 10 min. Exposure of the cornea to this UV-A light regimen after topical administration of riboflavin (0.25%) has been shown to induce CXL of the corneal collagen fibrils, with a resultant increase in tensile strength and diameter of the collagen fibrils. Clinically, CXL has been shown to stabilize the corneal curvature in eyes with progressive keratoconus, with no significant change in the refractive index of the cornea. Numerous reports and a few clinical trials have also shown benefit in aiding resolution of infective corneal ulcers.
Read the detailed description
This is a prospective, 2-arm parallel-group, single-blind, randomized multicenter study to determine the safety and effectiveness of the PXL Platinum 330 System for performing CXL in eyes with refractory corneal ulcers. Subjects with a history of non-resolving infective corneal ulcers will be evaluated initially for suitability as a candidate for CXL. Subjects who are candidates for CXL will be asked to participate in this study and will undergo the required screening procedures to determine study eligibility. Informed consent will be obtained from each subject before performance of any required study procedures that are not part of the investigator's routine examination. After completing screening procedures, the diagnosis for each eligible eye will be confirmed. Subjects will be randomized to 1 of 2 groups:
- Group 1: Standard-of-care therapy (anti fungal drops if there is clinical suspicion for fungus, fortified antibiotics if corneal culture is positive for a specific organism sensitive to a fortified antibiotic, and empiric antibiotic drops based on community prevalence if corneal culture is negative and there is no clinical suspicion for fungus)
- Group 2: Standard-of-care therapy + CXL
Eyes undergoing CXL will have topical anesthetic administered and then have topical riboflavin instilled onto the cornea every 2 min (or longer as needed to assure adequate corneal penetration), after which the cornea will be exposed to UV-A pulsed light 18 mW/cm2 for 10 min. Riboflavin instillation will continue every 2 min during CXL. The CXL procedures will be performed on an outpatient basis using the PXL Platinum 330 System (UV-A light source and riboflavin solution). All use of the PXL Platinum 330 System will be in accordance with this protocol and the general instructions provided by the manufacturer (PESCHKE) in the PXL Platinum 330 Illumination System Operator's Manual. All subjects will be evaluated at Screening/Baseline, Day 0 (Randomization/Treatment), Day 1, Day 3 ( +/- 1 day), Week 1 ( +/- 2 days), Week 2 ( +/- 2 days), Week 4 ( +/- 3 days), and Week 6 ( +/- 4 days) after treatment. Efficacy monitoring throughout the study will include observations at appropriate times for re-epithelialization, size of infection, and corneal culture results. Safety monitoring throughout the study will include observations at appropriate times for pain, IOP, BSCVA, corneal scar size, AEs, clinically significant findings on ophthalmic examination, dilated fundus examination, and slit lamp examination. After treatment, subjects will be followed at the treating physician's discretion.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PXL Platinum 330 system + Riboflavin 0.25% TE SolutionCombination product
Standard-of-care therapy (antifungal drops or fortified antibiotics and empiric antibiotic drops). In addition CXL + Riboflavin 0.25% TE solution.
After topical anesthesia, the surgeon or trained designee will apply topical riboflavin (1 drop every 2 min for 40 min with PESCHKE TE solution [0.25%], or longer as needed to assure adequate corneal penetration). At the end of this pre-treatment period, the eye will be examined at the slit lamp with the blue filter for the presence of riboflavin throughout the stroma. When sufficient corneal riboflavin penetration is confirmed, the eye will be aligned under the PXL Platinum 330 light. The correct aperture setting (3 to 12 mm) will be selected for the size of the eye and area needing to be treated (2 mm larger than the maximal ulcer diameter), and the eye will be irradiated at 18 mW/cm2, with pulsed mode (5 seconds on, 5 seconds off) for 10 min, during which time instillation of riboflavin will continue (1 drop every 2 min).
Sham CXL + Artificial TearsOther
Standard-of-care therapy (antifungal drops or fortified antibiotics and empiric antibiotic drops). In addition, for subjects in the sham group, artificial tears (1 drop every 2 min for 40 min) will be administered. after instillation of artificial tears, the eye will be aligned under the PXL Platinum 330 light. The instrument will be kept off and the subject will be kept under the device for 10 min during which time instillation of artificial tears will be performed (1 drop every 2 min) to maintain corneal hydration. The operator will keep track of sham exposure time independently to confirm the actual duration.
| Study group | Role | What they receive |
|---|---|---|
| Standard of care + Sham CXL + Artificial Tears | Sham comparator | Standard-of-care treatment and Sham CXL and administration of artificial tears. Receives: Other: Sham CXL + Artificial Tears |
| Standard of care + CXL + Riboflavin 0.25% TE Solution | Experimental | Standard of care treatment and the experimental combination product. The PXL Platinum 330 Illumination System is a portable electronic medical device. The device's light emitting diode (LED) is used to deliver a metered dose of UV-A light to a targeted treatment area for illuminating the cornea during corneal collagen CXL. The riboflavin solution is an isotonic (0.9%) sodium chloride solution containing 0.25% riboflavin, 1% hydroxypropylmethylcellulose, and 0.007% benzalkonium chloride, adjusted to a pH of 7.0, and packaged in 2 mL sterile syringes for topical ophthalmic use. Receives: Combination Product: PXL Platinum 330 system + Riboflavin 0.25% TE Solution |
What is being measured
The primary outcome is the main question the study is designed to answer.
The primary objective of this study is to evaluate the safety and effectiveness of corneal collagen CXL (performed using the PXL-Platinum 330 system with riboflavin solution) for treating refractory corneal ulcers.
Primary Outcome Measure:
- The composite primary endpoint outcome would be the proportion of patients in the treated group, compared to the control group, who achieve all three of the following components:
- complete re-epithelialization at week 2, defined as absence of corneal fluorescein staining noted with the blue light of the slit lamp by the investigator.
- no expansion of infiltrate from baseline to week 2. The size of the infiltrate will be reviewed by the investigator using the slit lamp exam and compared to baseline measures to assess expansion of the infiltrate.
- a negative corneal culture at week 2
- Each of the components of this composite endpoints is a binary outcome (yes or no), and are NOT measured as units of measure.
Measured: Week 2 (#+/- 2 study days).

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 6 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 28 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 12 sites in United States. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Patricia Huezo-Diaz Curtis, PhD (0041 (0) 787 422151, Patricia.Huezo-Diaz@confinis.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
