简要总结
The main objective of this study is to assess the clinical and mechanistic effect of using Ocular surface immunoglobulin (OSIG) eye drops for treating Dry Eye Disease. Therefore, the investigator will perform a prospective, phase II, randomized, placebo-controlled, double-masked, tolerability and efficacy clinical trial using OSIG-eye drops in patients with Dry Eye Disease. This clinical trial will be powered to detect efficacy of the treatment.
This will be a Randomized controlled trial, in which a total of 40 subjects will be enrolled at one clinical site. Subjects will be randomly assigned to one of two groups (#1, #2), with 20 subjects per group. One group will be given placebo (Normal saline eye drops) and the other group will be given eye drops containing the study drug (OSIG). Treatment will be for eight weeks.

入选标准
- •Able to Sign and date the informed consent form approved by the Institutional Review Board (IRB)
- •≥ 18 years of age
- •Patient reported dry eye-related ocular symptoms for at least 3 months before the Screening Visit and use or desire to use artificial tears, ointments or dry eye treatments in the 2 weeks preceding the screening visit
- •Women must be post-menopausal ≥ 1 year, or surgically sterilized. If not, a negative urine pregnancy test is required within 14 days of receiving her first dose of test medication (placebo/ study drug) along with definite evidence of contraceptive use during the duration of the study. Women of reproductive age should use a method of birth control that is acceptable to the subject and the study doctor. This may include oral contraceptive pills, birth control implants, barrier methods or abstinence. If a subject mentions she suspects she may be pregnant after being enrolled, another pregnancy test will be administered. If the test is positive, she will be discontinued from the study immediately.
- •Be willing/able to return for all study visits and to follow instructions from the study investigator and his staff
排除标准
- •Inability to provide informed consent.
- •Vulnerable populations, such as neonates, children, prisoners, institutionalized individuals, or others who may be considered vulnerable populations.
- •Contact lens wear within two weeks of baseline visit.

结局指标
主要结局
Mean reduction in Epitheliopathy at week 8, compared to day 1 (pre-dose), as measured by corneal staining score using National Eye Institute (NEI) grading scale.
时间窗: 8 Weeks
Corneal staining score as measured by Lissamine Green dye staining using National Eye Institute (NEI) grading scale. Dye is applied to each eye and a slit lamp is used to observe corneal staining. NEI scale relies on a chart that divides the cornea into 5 sections and assigns a value from 0 (absent) to 3 (severe) to each section, based on the density of punctate staining, final staining score being the sum of individual section scores with a range of 0 (minimum) -15 (maximum) points. Complete corneal staining clearance with Lissamine dye defined as a score of 0 indicating the best outcome.
Mean reduction in Dry Eye Disease (DED) symptoms as measured by the Ocular surface disease index (OSDI) score at 8 week, compared to day 1 (pre-dose)
时间窗: 8 Weeks
Ocular Surface Disease Index (OSDI), a 12-item questionnaire, assesses symptom of ocular irritation in dry eye disease (DED) and how it affects functioning related to vision in the past week. It has 3 subscales: ocular symptoms, vision-related function, and environmental triggers. Patients rate their responses on 0 to 4 scale with 0 being "none of the time" and 4 being "all of the time." OSDI score range from 0-100 with score 0-12 being normal, 13-22 being mild DED, 23-32 being moderate DED, and \>33 being severe DED. OSDI=\[(sum of scores for questions answered)×100\]/\[(total questions answered)×4\]
