Study Design
Structure: Multicenter, randomized, double-masked, vehicle-controlled, parallel group study Duration: 1 month of TID treatment Treatment Groups, Dosing, and Treatment Regimen Study Treatment: CBT-008 topical ophthalmic solution Control Treatment: CBT-008 vehicle
详细描述
Structure Multicenter, randomized, double-masked, vehicle-controlled, parallel group study.
Duration Stage 1: 1 month Stage 2: 1 day (1 dose)
Treatment Groups, Dosing, and Treatment Regimen
- Study Treatment Stage 1: CBT-008 ophthalmic solution was administered as 1 drop OU TID Stage 2: CBT-008 ophthalmic solution was administered as 1 drop in the study eye
- Control Treatment CBT-008 vehicle
- Methods for Masking Study medication will be packaged in identical kits and will be labeled with medication kit numbers. The central randomization system will provide the site with a specific medication kit number for the patient corresponding to the treatment group assigned.
- Instructions for Storage, Use, and Administration Study medication will be supplied as preservative free-unit dose containers, where 1 mL of CBT-008 ophthalmic solution will be aseptically filled into 3 mL Low Density Polyethylene (LDPE) ophthalmic dropper bottles. Study medication should be stored at room temperature in a secure area at clinical sites and dispensed only to patients enrolled into the clinical study. Patients will be instructed to store study medication in a cool place at room temperature at home. Study medication will be administered TID, one drop, to both eyes. First instillation of study medication on the first day will be applied by subject or care provider with site staff's observation for training and supervision. During the rest of the study treatment, patients will self-administer the medication TID for 1 month.

- •Visual Analog Scale (VAS) level is 35-90% for at least 1 of the 7 categories
- •Total Cornea staining grade ≥ 3 (NEI scheme with max score = 15)
- •Total meibum quality score (MQS) is between 6-17 from the sum of the 6 lower eyelid central glands in at least one lower eyelid (0-3 scale with max total = 18).

- •Stage 2 inclusion criteria
- •Patients who completed the Stage 1 Exit Visit for at least 1 month or healthy volunteers
- •At least 18 years of age at time of consent and able to provide written informed consent
排除标准
- •Stage 1 exclusion criteria
- •Uncontrolled systemic disease in the opinion of the Investigator
- •Active allergies with symptoms that may confound the data, active ocular infection requiring treatment, or ocular surface inflammatory disease unrelated to MGD or DED, including chalazion, inflamed pinguecula, and viral illness
- •History of ocular herpes disease in either eye
- •Incisional ocular surgery within 6 months or ocular laser surgery within 3 months
- •Use of topical treatment of the eye/eyelid with antibiotics, NSAIDS, or vasoconstrictors to treat MGD or DED within 14 days of screening; steroids, cyclosporin A or lifitegrast within 28 days of screening
- •Current or anticipated use of other topical ophthalmic medications in the study eye. (Patients must have discontinued the use of ophthalmic medications in the study eye for at least 2 weeks prior to the screening visit, the use of diagnostic medications as part of the eye exam prior to screening and artificial tears is allowed.)
- •Anticipated wearing of contact lenses during any portion of the study. (Patients, who wear soft contact lenses should discontinue wearing them at least 3 days prior to screening visit. Patients wearing rigid gas permeable or hard contact lenses should discontinue wearing them at least 3 weeks prior to screening visit.)
- •Active rosacea involving the eyelids within 60 days of screening
- •Current enrollment in an investigational drug or device study or participation in such a study within 30 days prior to entry into this study
- •Any condition or situation which, in the investigator's opinion, may put the patient at significant risk, may confound the study results, or may interfere significantly with the patient's participation in the study
- •Female patients who are pregnant, nursing, or planning a pregnancy during the study Stage 2 exclusion criteria
- •Females who were pregnant or nursing
- •Current enrollment in an investigational drug or device study or participation in such a study within 30 days prior to entry into this study
