Brief Summary

This is a phase 2, multicenter, double-blind, placebo control, randomized study to evaluate the efficacy and safety of orally administered SA001 compared to placebo in patients with Dry Eye Syndrome. The clinical trial consists of a wash-out period of 14 days, a treatment period of 12 weeks, and a follow-up period of 1 week after administration of the Investigational Product. If the subject voluntarily signs the informed consent form(ICF), the investigator conducts screening tests and check medical history to evaluate the subject's suitability. As a result of the screening test, eligible subjects should stop using the prior medication for dry eye syndrome during the 14 days of observation period, and if necessary, subjects can use rescue drug(artificial tears) for the first 11 days, and then discontinue all eye drops including rescue drug(artificial tears) for 3 days. And all of these subjects will be randomized in a 1:1:1:1 ratio to receive 3 different doses of investigational product (SA001 or placebo) everyday for 12 weeks. During the treatment period, If necessary, subjects can use the rescue drug (artificial tears), and the number of administration of rescue drug is limited to 3 times a day, and when used, the administration time should be recorded in the subject's diary. Subjects should visit to the study site on 2, 4, 8 and 12 weeks after starting dosing investigational product. Efficacy evaluation results are collected from both eyes, and the primary evaluation variable is analyzed using the test results collected from 'Worse eye' (the eye with the worse keratoconjunctival staining result among both eyes). Worse eye will be determined at the baseline visit and, if the results of both eyes are the same, the test result of the left eye is used.

You may qualify if:

• Age over 19
• Patient who meets all of the following criteria in at least one of both eyes
• Fluorescein corneal staining score ≥ 2
• Schirmer test ≤ 10mm in 5 mins

• Patient who can understand the clinical trial and voluntarily signs an informed consent

You may not qualify if:

• Clinically significant ophthalmic diseases not caused by dry eye disease (corneal surface disease, abnormal corneal sensitivity, abnormal tear excess, etc.) that may confuse the interpretation of clinical trial results
• In case of being treated with anti-inflammatory therapy for dry eye, such as steroid or non-steroidal anti-inflammatory eye drops, autologous serum eye drops, etc.
• In case of administration of steroids or immunosuppressants (azathioprine, tacrolimus, cyclosporine, mofetil mycophenolate, etc.)
• Patient who has worn contact lenses within 72 hours prior to screening or need to wear contact lenses during the clinical trial period
• A history of intraocular surgery within 90 days prior to screening
• Active eye infection symptoms such as anterior uveitis, anterior blepharitis, and Steven-Johnson syndrome

• Autoimmune disease (ex. Sjögren's syndrome, Rheumatoid arthritis, systemic lupus erythematosus, Graves' disease, etc.)
• Patient who needs surgery due to surface elevation caused by Meibomian Gland Dysfunction (MGD)
• A history of corneal transplantation or neurotrophic keratitis
• Patient who has an intraocular pressure of 25 mmHg or higher in one or more of both eyes or have been diagnosed with glaucoma
• Patient who has undergone vision correction surgery such as LASIK (Laser-Assisted in Situ Keratomileusis) within 12 months prior to screening
• Patient who has undergone silicone lacrimal punctal occlusion or cauterization of the punctum within 90 days prior to screening. However, patient who has undergone collagen lacrimal punctal occlusion can be enrolled.
