简要总结
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).
详细描述
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.
- Schirmer's Test
- Ocular Surface Disease Index (OSDI)
- Tear Film Break-Up Time (TBUT)
- Standard Patient Evaluation of Eye Dryness (SPEED)
- Corneal and Conjunctival Staining
- Tear Osmolarity
- MMP-9 biomarker

入选标准
- •Male and/or female subjects aged between 18 and 65 years (both limits inclusive).
- •Clinical diagnosis of symptomatic Dry Eye Syndrome confirmed by a licensed optometrist at Baseline by presence of irritation, foreign body (sandy) sensation, feeling of dryness, itching, non-specific ocular discomfort and altered/effected QoL at least in any one of the eyes.
- •Subjects shall be in good health and free from any clinically significant disease, other than Dry Eye Syndrome (DES), that might interfere with the study evaluations.
- •Subjects must meet the following criteria in at least one eye, as determined by a licensed optometrist:
- •i. Schirmer's Test without anesthesia ≤ 10 mm ii. Ocular Surface Disease Index (OSDI) Test symptoms between 12 and 40
- •Subjects with any of the following in at least one eye, as determined by a licensed optometrist:
- •i. Tear film break up time ≤ 10 seconds ii. Tear Osmolarity ≥ 316 milliosmole /L iii. Fluorescein corneal staining ≥ 1 and <
- •Subject willing to provide written consent.
- •Subjects shall be willing and able to understand and comply with the requirements of the study, administer the study product as instructed, return for the required treatment period visits, comply with therapy prohibitions, and be able to complete the study.
排除标准
- •Subjects who are pregnant, nursing, or planning a pregnancy within the study participation period.
- •History of allergy or sensitivity to Lutein, Zeaxanthin, Curcumin or Vitamin D3, related compounds or any component of the formulation.
- •Presence of severe dry eye syndrome with complications such as perforated Corneal Ulcer, Uveitis and Glaucoma, in the Investigator's opinion that may interfere with the evaluation of the Subject's Dry Eye Syndrome (DES).
- •Current evidence of ocular infections or inflammatory conditions like acute conjunctivitis or other medical condition that, in the Investigator's opinion, would place the Subject at undue risk by participating or compromise the integrity of the study data.
- •Subject with poorly controlled diabetes mellitus, rheumatoid arthritis and Systemic Lupus Erythematosus (SLE) which causes Dry Eye Syndrome.
- •Subjects with herpetic eye disease.
- •Subjects with chronic infection of the lacrimal gland.
- •Subjects with Laser In Situ Keratomileusis (LASIK).
- •Subjects with poorly controlled hypertension (>140/96 mm of Hg).
- •Subjects with evidence of malignancy.
- •Subjects suffering from major systemic illness necessitating long term drug treatment (Psychological, Neurological, Endocrinal, Cardiovascular disorders, etc.).
- •Subjects with concurrent serious Hepatic Dysfunction or Renal Dysfunction, uncontrolled Pulmonary Dysfunction (asthmatic and Chronic Obstructive Pulmonary Disease (COPD) Subjects) or other concurrent severe disease.
- •Any ocular trauma or surgery that may affect corneal sensitivity and/or normal tear distribution (e.g., cataract surgery, refractive surgery) within the 6 previous months to study inclusion
- •Subjects with inability to swallow soft gel capsules.
- •Use of lutein, zeaxanthin, curcumin, or vitamin D3 on prescription for other medical indications or for health-conscious reasons
- •Use of steroids or hormone replacement therapy or any other medication that may adversely affect the outcome of the study.
- •Subjects on aspirin or anti-coagulant therapy.
- •Subjects with any other medical condition that might adversely impact the safety of the study participants or confound the study results.
研究组 & 干预措施
Placebo
Consume one capsule every morning after the breakfast at the same time every day for 56 days
干预措施: Placebo (Dietary Supplement)
结局指标
主要结局
Schirmer's Test (without anesthesia)
时间窗: Baseline, Day 14, Day 28, Day 56
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)
Ocular Surface Disease Index (OSDI) score
时间窗: Baseline, Day 14, Day 28, Day 56
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.
