Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • be at least 18 years of age of either gender and any race
  • have at least a two-year history of moderate-to-severe ragweed-induced allergic conjunctivitis based on principal investigator's judgement
  • have a positive skin prick test to ragweed pollen within the past year of screening

Exclusion criteria

Exclusion Criteria:

  • known or to any components of the product medication or components
  • history of uveitis, blepharitis, dry eye syndrome, herpes simplex keratitis, or herpes zoster keratitis;
  • presence of any ocular infection (bacterial, viral, or fungal) or active ocular inflammation (e.g., follicular conjunctivitis, allergic conjunctivitis) within 14 days prior to screening
  • presence of any chronic ocular degenerative condition or ocular inflammation that, in the opinion of the investigator, is likely to worsen over the course of the clinical trial;
  • diagnosis of moderate-to-severe pinguecula or pterygium (particularly if it results in chronic erythema), Stevens-Johnson Syndrome, ocular cicatricial pemphigoid, mucous membrane pemphigoid, significant conjunctival scarring, chemical burn, herpetic or neurotrophic keratitis, Cryopyrin Associated Periodic Syndrome (CAPS), or keratoconus
  • woman of who is pregnant or nursing
Terms in these criteria, in plain language(4)

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

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.

What researchers measure

Primary outcomes

  1. Subject-Reported Ocular Itching Score Assessed Over 110 to 210 Minutes in the Allergy Chamber

    Change from baseline comparison of reproxalap to vehicle for ocular itching on a 0 to 4 scale ( 0 = none, 4 = severe). The treatment comparison was performed using a mixed model repeated measures approach for a crossover trial with two treatment periods. The model included time point, treatment, treatment period, treatment sequence, and interaction between time point and treatment as fixed effects, and subject nested within treatment sequence as a repeated measure.

    Time frame: The efficacy assessment period was 110 to 210 minutes in the allergy chamber; baseline was pre-Dose #1 for each treatment period.

Secondary outcomes

  1. Conjunctival Redness Score Assessed Over 12 to 212 Minutes in the Allergy Chamber

    Change from baseline comparison of reproxalap to vehicle for conjunctival redness on a 0 to 4 scale ( 0 = none, 4 = extremely severe). The treatment comparison was performed using a mixed model repeated measures approach for a crossover trial with two treatment periods. The model included time point, treatment, treatment period, treatment sequence, and interaction between time point and treatment as fixed effects, and subject nested within treatment sequence as a repeated measure.

    Time frame: The efficacy assessment period was 12 to 212 minutes in the allergy chamber; baseline was pre-Dose #1 for each treatment period.
