Nasal Spray Study in Sjogren's Dry Eye Disease

Inclusion Criteria: Provide signed written consent prior to study-related procedures Be at least 22 years of age at the screening visit Have diagnosed moderate to severe Sjogrens Syndrome via blood work or biopsy Category 2 staining score for Conjunctiva based on the Van Bjisterveld and Utrect scale and 3 staining score for cornea based on the NEI scale Have been using Cyclosporine or Lifitegrast 3 months Be literate and able to complete questionnaires independently Be able and willing to use the study drug and participate in all study assessments and visits Have sufficient hand strength, in the opinion of the Investigator, to be able to independently administer the study drug Have provided verbal and written informed consent If a female is of childbearing potential, they must: use an acceptable means of birth control (acceptable methods of contraception include: hormonal oral, implantable, injectable, or transdermal contraceptives, mechanical spermicide in conjunction with a barrier such as a diaphragm or condom, IUD, or surgical sterilization of partner), and have a negative urine pregnancy test on Day 1 Exclusion Criteria: Have undergone previous ocular surgery (e.g., intraocular, oculoplastic, corneal or refractive surgical procedure) Have had thermal pulsation or IPL in prior 3 months Have used topical ophthalmic corticosteroid therapy in prior 4 weeks Have had cataract surgery in the last 6 months Have clinically significant ocular trauma. Have active ocular Herpes simplex or Herpes Zoster infection Have ocular inflammation (uveitis, iritis, scleritis, episcleritis, keratitis, conjunctivitis) at the discretion of the investigator. Have ocular infection (e.g., viral, bacterial, mycobacterial, protozoan or fungal infection or the cornea, conjunctiva, lacrimal gland, lacrimal sac or eyelids including hordeolum/stye). Have retinal pathology that can limit visual potential and refractive outcomes in the opinion of the investigator Have severe (Grade 3 or 4) inflammation of the eyelid (e.g., blepharochalasis, staphylococcal blepharitis or seborrheic blepharitis) Have eyelid abnormalities that significantly affect the lid function (e.g., entropion, ectropion, tumor, edema, blepharospasm, lagophthalmos, severe trichiasis, severe ptosis). Have ocular surface abnormality that may compromise the corneal integrity (e.g., prior chemical burn, recurrent corneal erosion, corneal epithelial defect, Grade 3 corneal fluorescein staining, map dot fingerprint dystrophy, or the effect of any other ophthalmic medication that might in the opinion of the investigator compromise the ocular surface integrity). Have a systemic condition or disease not stabilized or judged by the Investigator to be incompatible with participation in the study or with the lengthier assessments required by the study (e.g., current systemic infection, uncontrolled autoimmune disease, uncontrolled immunodeficiency disease, history of myocardial infarction or heart disease, etc.) Have chronic or recurrent epistaxis, coagulation disorders or other conditions that, in the opinion of the Investigator, may lead to clinically significant risk of increased bleeding. Have had nasal or sinus surgery (including history of application of nasal cautery) or significant trauma to these areas Be currently treated with nasal continuous positive airway pressure Have any untreated nasal infection at Visit 1 Have a vascularized polyp, severely deviated septum, chronic recurrent nosebleeds, or severe nasal obstruction as confirmed by intranasal examination performed at Visit 1. Have a known hypersensitivity to any of the procedural agents or study drug components Be currently enrolled in an investigational drug or device study or have used an investigational drug or device within 30 days prior to Visit 1 and during the treatment period. Be a female who is pregnant, nursing, or planning a pregnancy at Visit 1. Be a woman of childbearing potential who is not using an acceptable means of birth control; acceptable methods of contraception include: hormonal oral, implantable, injectable, or transdermal contraceptives; mechanical spermicide in conjunction with a barrier such as a diaphragm or condom; IUD; or surgical sterilization of partner. The risks of OC-01 among pregnant patients are not known.
