COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Eligibility
Key inclusion criteria
Participants with persistent corneal epithelial defect (PCED) of at least 10 days refractory to one or more conventional non-surgical treatments in study eye (e.g., preservative-free artificial tears, gels or ointments; therapeutic contact lenses).

Participants with corneal burns occurring within 24 hours prior to commencement of intervention.
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Participants with severe eyelid abnormalities contributory to the persistence of the persistent corneal epithelial defect (PCED).

Any active ocular infection (bacterial, viral, fungal or protozoal) based on corneal and bacterial cultures taken during the screening period.

More than one distinct PCED in the study eye.

Evidence of corneal ulceration involving the posterior third of the corneal stroma, corneal melting or perforation in the study eye

Presence or history of any ocular or systemic disorder or condition that may hinder the efficacy of the study treatment or its evaluation, could possibly interfere with the interpretation of study results, or could be judged by the Investigator to be incompatible with the study visit schedule or conduct (e.g., progressive or degenerative corneal or retinal conditions, uveitis, optic neuritis, poorly controlled diabetes, autoimmune disease, systemic infection, neoplastic diseases).

Summary
Brief summary
This Phase 1b study is designed to assess the safety and tolerability of repeated topical ocular administration of CMB-012, 2 times per day , in participants with chemical burns of the cornea and/or persistent corneal epithelial defect, to allow a preliminary assessment of a safe and efficacious dose to be studied in further clinical studies.
