Clinical Trial Summary

This is a prospective, randomized, double-blind, parallel, placebo-controlled, clinical interventional study. The purpose of this study is to evaluate the efficacy and safety of Nutritears®, a dietary supplement of OmniActive Health Technologies, in adult subjects with dry eye syndrome (DES). Subjects shall be instructed to consume one capsule of their assigned investigational study product every morning after the breakfast, at the same time every day, for 56 days (8 weeks).

Description:

Dry eye syndrome (DES) affects a significant population around the world. Tear film moistens and prevents the ocular surface from dust, toxins, pollutants, etc. An imbalance in any of the tear film layers accompanied by glandular dysfunction leads to DES and it affects the ocular surface. The symptoms include discomfort, visual disturbance, inflammation, damage to ocular surface and tear film instability. This is a prospective, randomized, double-blind, parallel, placebo-controlled, clinical interventional study. The purpose of this study is to evaluate the efficacy and safety of Nutritears®, a dietary supplement of OmniActive Health Technologies, in adult subjects with dry eye syndrome (DES).

After the informed consent process, completion of all screening assessments and once all the inclusion/exclusion criteria are met, the eligible subjects shall be enrolled in the study. Medical history, including a complete review of all current and past diseases and their respective treatments, will be performed during the screening visit. Physical examination including detailed ocular examination and vital signs (like blood pressure, pulse rate, oxygen saturation and body temperature) will be done during screening. Interviews will be conducted to assess/obtain the medical history, ophthalmic history, systemic disease history, current occupation, exposure to air, presence of allergic problems or concomitant systemic diseases, topical and systemic medications, spectacles/contact lens usage, oral contraceptives, significant history of trauma, chemical burns, drug reactions, history of using any kind of tear substitute, other connective tissue disorder and any history of ocular surgery shall be obtained. Digital screen exposure time from devices like computers, laptops, televisions, tablets, and mobile phones will be recorded.

The following screening tests and procedures shall also be conducted on each potential subject prior to consideration for inclusion into the study:

If the clinical signs and symptoms of DES are present, the following test shall be performed on both the eyes of each subject.

1. Schirmer's Test

2. Ocular Surface Disease Index (OSDI)

3. Tear Film Break-Up Time (TBUT)

4. Standard Patient Evaluation of Eye Dryness (SPEED)

5. Corneal and Conjunctival Staining

6. Tear Osmolarity

7. MMP-9 biomarker

If the subject is eligible as per the inclusion/exclusion criteria then, at Randomization Visit, subjects will be randomly (Double-blind) assigned in 1:1 ratio to one of the two (2) treatment groups i.e., Nutritears® or Placebo at Visit 2.

Subjects will be instructed to consume one capsule every morning after the breakfast, at the same time every day, for 56 consecutive days (8 weeks).

Subjects shall complete five scheduled clinic visits as follows:

• Visit 1: Screening Visit (Day -7 to Day -1) • Visit 2: Randomization Visit (Day 1)

• Visit 3: First Follow-Up Visit (Day 14 ± 3 days)

• Visit 4: Second Follow-Up Visit (Day 28 ± 3 days)

• Visit 5: End of Treatment Visit (Day 56 + 3 days) Total study duration for the clinical part shall be a maximum of 66 days which includes the screening period of 7 days, followed by the treatment period of 56 (8 weeks) and an End of study visit at 56 + 3 days.

Safety assessments include monitoring of adverse events (AEs), physical examination, vital signs (heart rate, blood pressure, oxygen saturation, body temperature) and laboratory assessments. Clinical assessments include the Schirmer's Test, Ocular Surface Disease Index (OSDI), Tear Film Break-Up Time (TBUT), Standard Patient Evaluation of Eye Dryness (SPEED) and Corneal and Conjunctival Staining, Tear Osmolarity and MMP-9 biomarker.

A subject diary shall be provided to the subjects to record the Investigational Product administration details, rescue medication (artificial tears) usage, side effects, and concomitant medication details. All subjects shall be instructed to complete the subject diary after each investigational study product administration. Any additional and missed administrations should also be noted in the subject diary. The daily dosing data shall be used to evaluate compliance. Statistical comparisons for therapeutic efficacy shall be made between Nutritears® to the Placebo product.

Primary	Schirmer's Test (without anesthesia)	Change from Baseline in the length of wetting on a sterile Schirmer's Test strip.; Without previously instilling anesthetic drops, the Schirmer strip is inserted into the lower conjunctival sac at the junction of the lateral and middle thirds, avoiding touching the cornea, and the length of wetting strips in millimeters is recorded after 5 minutes. The patients will be instructed to close their eyes gently. After 5 minutes have elapsed, the Schirmer test strip will be removed and the length of the tear absorption on the strip will be measured (millimeters/5 minutes)	Baseline, Day 14, Day 28, Day 56
Primary	Ocular Surface Disease Index (OSDI) score	Change from Baseline in Ocular Surface Disease Index score. The Ocular Surface Disease Index (OSDI) is a 12-item questionnaire designed to provide a rapid assessment of the symptoms of ocular irritation consistent with dry eye disease and their impact on vision-related functioning.; The overall OSDI score defines the ocular surface as normal (0-12 points) or as having mild (13-22 points), moderate (23-32 points), or severe (33-100 points) disease.	Baseline, Day 14, Day 28, Day 56
Secondary	Tear Film Break-Up Time (TBUT)	Change from Baseline in the number of seconds that elapse between the last blink and the appearance of the first dry spot in the tear film. A TBUT greater than 15 seconds is considered normal, while a break time of less than 10 seconds is to be considered pathological.	Baseline, Day 14, Day 28, Day 56
Secondary	Standard Patient Evaluation of Eye Dryness (SPEED) score	Change from Baseline in the subjects' perception of eye dryness as assessed by Standard Patient Evaluation of Eye Dryness (SPEED) score.; The SPEED questionnaire was designed in order to quickly track the progression of dry eye symptoms over time. This questionnaire gives a score from 0 to 28 that is the result of 8 items that assess frequency and severity of symptoms. The symptoms assessed include dryness, grittiness, scratchiness, irritation, burning, watering, soreness, and eye fatigue. The questionnaire further assesses whether these symptoms were not problematic, tolerable, uncomfortable, bothersome, or intolerable	Baseline, Day 14, Day 28, Day 56
Secondary	Corneal and Conjunctival Staining	Change from Baseline in Corneal and Conjunctival Staining.; Corneal and conjunctival staining of the ocular surface after instillation of vital dyes was developed to quantify epithelial surface damage in dry eye patients. A modified Oxford score is used to separately score cornea and conjunctiva from 0 to 5 (from 0 = none to 5 = extended areas of confluent stain).	Baseline, Day 56
Secondary	Tear Osmolarity	Change from Baseline in Tear Osmolarity; Tear osmolarity refers to the amount of osmotically active particles. Tear osmolarity is abnormal at values greater than 300 milliosmole/L.	Baseline, Day 56
Secondary	MMP-9	Change from Baseline in tear inflammatory marker MMP-9.; InflammaDry MMP-9 test kits (QUIDEL, CA, USA) are used for qualitative determination of MMP-9 presence in both eyes. A positive MMP-9 result indicates the presence of MMP9 greater than or equal to 40 ng/ml, and a negative one indicates the presence of MMP-9 less than or equal to 40 ng/ml.	Baseline, Day 56
Secondary	Rescue Medication Use	Change from Baseline in rescue medication use	Baseline, Day 56
