About
This is a phase III, multicenter, randomized, double-masked, Active-controlled design. The aims to confirm previous findings of the efficacy and safety of CsA-PG Ophthalmic Gel by comparing it to CsA Ophthalmic Gel for treating dry eye symptoms.
Full description
396 subjects will be enrolled (198 in each treatment group). Subject selection will be conducted during a 14-day run-in period before randomization. After the screening, subjects will receive lubricant eye drops (Refresh Tears®, Carboxymethylcellulose Sodium (0.5%)) treatment bilaterally BID for 14 days. Eligible subjects will be randomized (1:1) and receive the experimental drug or control drug , administered bilaterally once daily for 84 days.

Have a reported history of dry eye for at least 6 months before Visit 1;
Have a clinical diagnosis of bilateral dry eye disease, including all of the following scored in at least one eye at both Visits 1 and 2;
Exclusion criteria
Clinical diagnosis or history of any clinically significant ocular diseases/disorders (e.g., age-related maculopathy that requires treatment and/or in the opinion of the Investigator may interfere with study parameters in Visit 1 and/or Visit 2;
Any active ocular or systemic infection (e.g., bacterial, viral, or fungal) at Visit 1 and/or Visit 2;
Any active ocular inflammation (e.g., iritis, uveitis, allergic conjunctivitis) at Visit 1 and/or Visit 2;
Any conjunctival scarring history (Such as with irradiation, alkali burns, Steven Johnson syndrome, Sjogren's syndrome, cicatricial pemphigoid) or destruction of conjunctival goblet cells (e.g., neurotrophic keratitis, vitamin A deficiency) before Visit 1;
Have worn contact lenses within 14 days of Visit 1 or anticipate using contact lenses during the study;
Have any refractive surgery and/or any other ocular surgical procedure within 3 months before Visit 1; or have any ocular surgical procedure scheduled to be conducted during the study period;
Have eyelid surgery within 6 months before Visit 1 or planned eyelid surgery during the study period;
Have Nd:YAG (neodymium-doped yttrium aluminum garnet) laser capsulotomy within 6 months before Visit 1;
Have used temporary (i.e., collagen) punctual plugs within 3 months before Visit 1 or anticipate their use during the study period;
Have permanent punctual plugs inserted or have surgical punctual occlusion before Visit 1 or anticipate any such event during the study period;
Use any of the following treatments in the period indicated before Visit 1 or anticipate their use at any time during the study.
Topical medications(30 days prior to Visit 1):
Systemic medication (30 days before Visit 1):
Any systemic medication known to cause ocular drying (e.g., antidepressants, beta blockers) except if it was taken on a stable dosing regimen for at least 30 days before Visit 1 and is expected to be taken on the same regimen throughout the study period. The known systemic medications that can cause ocular drying include:
Non-medicine treatment (30 days before Visit 1):
Have a severe/serious systemic disease, chronic illness, or uncontrolled medical condition including, but not limited to, severe cardiopulmonary disease, poorly controlled hypertension, poorly controlled diabetes, and/or clinically significant (CS) hematologic, renal, or liver disease that in the opinion of the Investigator could interfere with study assessments or limit compliance;
Be a woman who is pregnant, nursing, or planning a pregnancy;
Be unwilling to submit a urine pregnancy test at Visit 1 and Visit 5 (or early termination visit) if of childbearing potential. The non-childbearing potential is defined as a woman who is permanently sterilized (e.g., has had a hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is post-menopausal (i.e., without menses for 12 consecutive months);
Be a woman of childbearing potential who is not using an acceptable means of birth control during the study period and 30 days after the end of the study. Acceptable methods of contraception include hormonal (e.g., oral, implantable, injectable, or transdermal contraceptives), mechanical (e.g., spermicide in conjunction with a barrier such as a diaphragm or a condom), intrauterine device (IUD), or surgical sterilization of partner. For non-sexually active females, abstinence might be regarded as an adequate method of birth control; however, if the subject becomes sexually active during the study, she must agree to use acceptable birth control as defined above for the remainder of the study;
Have a known hypersensitivity or contraindication to the investigational products (IPs) or their components;
Have a condition or be in a situation that the Investigator felt may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study (e.g., any planned procedure or surgery during the study period);
Be currently enrolled in an investigational drug or device study or have used an investigational drug or device within 30 days before Visit 1;
In the opinion of the Investigator, be unable or unwilling to comply with the study protocol, including participation in all study assessments, visits, and dosing, or be unable to instill eye drops successfully.
