Study summary

This is a Phase 3 study to evaluate the safety and efficacy of a vancomycin hydrochloride ophthalmic ointment dosed 4 times daily for 7 days compared to placebo (vehicle) in patients with moderate to severed Gram-positive bacterial conjunctivitis.

Read the detailed description

Bacterial conjunctivitis is common ocular disease caused by various types of bacteria including methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant Staphylococcus epidermidis (MRSE). External ocular infections such as those caused by MRSA or MRSE frequently are not serious but in rare cases may be severe enough to threaten vision. When ocular infections due to resistant organisms such as MRSA/MRSE do not respond to empiric treatment with approved antibiotics, there are few treatment options. Vancomycin is one of the few treatment options that has been shown to be effective against all clinical isolates of MRSA/MRSE.

This study is a Phase 3 study to evaluate the safety and efficacy of a vancomycin hydrochloride ophthalmic ointment in patients with moderate to severed Gram-positive bacterial conjunctivitis including those with MRSA and MRSE. Subjects, who are adenovirus negative, will be dosed with vancomycin hydrochloride ophthalmic ointment or placebo (vehicle) 4 times daily for 7 days and evaluated for clinical and bacterial resolution of their infection along with an assessment of the safety of the investigational product.

Snellen visual acuity (VA) equal to or better than 20/200 in each eye using current corrective lenses, if required (or if worn) and/or using pinhole if subject's corrective lenses are not available at the time of exam. Every attempt should be made to obtain a VA measurement in children and, if it is unobtainable, the decision as to whether the criterion is met will be at the investigator's discretion.

Women of childbearing potential must use an acceptable form of throughout the study. Acceptable methods include the use of at least one of the following: intrauterine (intrauterine device), hormonal (oral, injection, patch, implant, ring), barrier with spermicide (condom, diaphragm), or abstinence.
  6. Able to self-administer study medication or to have the study medication administered by a caregiver throughout the study period.
  7. Must have signed written consent from the subject prior to participation in any study-related procedures if the subject is 18 years of age or older, or from the legally authorized representative/guardian if the subject is under 18 years of age.
  8. Must have the signature of the subject on the assent form, as required by Institutional Review Board (IRB) guidelines, if the subject is under 18 years of age.

Exclusion criteria

Exclusion Criteria:

  1. Suspected viral or allergic conjunctivitis or suspected fungal or acanthamoeba infections at Screening in either eye.
  2. Suspected iritis/uveitis or episcleritis/scleritis at Screening in either eye or history of either condition.

  8. Use of topical ophthalmic antimicrobial therapy within 48 hours prior to Screening. Use of topical ophthalmic antimicrobial therapy other than study medication is prohibited throughout the study period in either eye.
  9. Use of topical ophthalmic anti-inflammatory agents (eg, nonsteroidal anti-inflammatory drugs [NSAIDs] or , including steroid-antibiotic combinations) within 48 hours prior to Screening and throughout the study period.

Terms in these criteria, in plain language(7)

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.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
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 Oct 23, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
