  • Patients with Conjunctivitis (defined as the presence of three cardinal signs: conjunctival discharge, bulbar conjunctival injection and palpebral conjunctival injection)
  • Patients who have given and signed
  • The ability and willingness to comply with all study procedures

Exclusion criteria

Exclusion Criteria:

  • Insulin Dependent Diabetes Mellitus (IDDM)
  • Patients with keratitis or hordeolum
  • Glaucoma
  • Sjogren's Syndrom and "Sick Eye's Syndrom".
  • Ectropion, entropion;
  • Using contact lenses during the study
  • Poor visual acuity in the other eye
  • Prior and concurrent concomitant treatment glycocorticosteroids, immunosupressive therapy, if these treatments have not stopped at least 3 months prior to the start of the study;
  • Concurrent use of non- steriodal anti- inflammatory drugs (NSAIDs), with the exception of low- dose aspirin. (see par. 11.5)
  • Prior and concurrent systemic antibiotic treatment during last 7 days before the beginning the study.(see par. 11.5)
  • Concurrent other eye drops
  • All ocular surgeries which were performed less than 6 months before the beginning of the study.
  • Any clinical condition, which, in the opinion of the investigator would not allow safe completion of the protocol.
  • History of any within the past 5 years prior to study entry, except basal cell or squamous cell skin carcinoma.
  • to fluoroquinolons and benzalkonium chloride;
  • Intended or ascertained pregnancy or lactation;
  • Participation in a clinical trial within last 30 days.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 29, 2007, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
