  • Have a positive bilateral post-CAC reaction (defined as having scores of ≥2 ocular itching and ≥2 conjunctival redness) for at least two out of the first three time points following the challenge at Visit 2.

You may not qualify if:

  • Each subject must not:
  • \. Have known contraindications or sensitivities to the use of the investigational product or any of its components; 2. Have any ocular condition that, in the opinion of the investigator, could affect the subject's safety or trial parameters (including but not limited to narrow angle glaucoma, clinically significant blepharitis, follicular conjunctivitis, iritis, pterygium, history of corneal transplantation or a diagnosis of dry eye); 3. Have had ocular surgical intervention within three (3) months prior to Visit 1 or during the study and/or a history of refractive surgery within the past six (6) months; 4. Have a known history of retinal detachment, diabetic retinopathy, or active retinal disease; 5. Have the presence of an active ocular infection (bacterial, viral, or fungal) or positive history of an ocular herpetic infection at any visit; 6. Use any of the following disallowed medications during the period indicated prior to Visit 1 and during the study: 7 Days
  • systemic or ocular H1-antihistamine, H1-antihistamine/mast cell stabilizers, H1-antihistamine-vasoconstrictor drug combinations;
  • decongestants;
  • monoamine oxidase inhibitors
  • all other topical ophthalmic preparations (including artificial tears)
  • lid scrubs;
  • topical prostaglandins or prostaglandin derivatives
  • ocular, topical, or systemic nonsteroidal anti-inflammatory drugs (NSAIDs, including baby aspirin (81 mg)) 14 Days

  • depo-corticosteroids; Note: Currently marketed over-the-counter anti-allergy eye drops (i.e. anti-histamine/vasoconstrictor combination products such as Visine®-A®) may be administered to subjects by trained study personnel at the end of Visits 1, 2 and 4b after all evaluations are completed.
  • \. Have any significant illness (e.g. any autoimmune disease requiring therapy, severe cardiovascular disease \[including arrhythmias\] the investigator feels could be expected to interfere with the subject's health or with the study parameters and/or put the subject at any unnecessary risk (includes but is not limited to: poorly controlled hypertension or poorly controlled diabetes, a history of status asthmaticus, organ transplants, a known history of persistent moderate or severe asthma, or a known history of moderate to severe allergic asthmatic reactions to any of the study allergens; 8. Have received allergy immunotherapy within the last 2 years; 9. Manifest signs or symptoms of clinically active allergic conjunctivitis in either eye at the start of Visits 1, 2, or 3 (defined as the presence of any itching or \>1 \[greater than 1\] redness in any vessel bed); 10.
