ClinConnect Summary

This clinical trial is studying a new eye drop solution called CAM-101, which is made from human platelets. It aims to see how effective and safe this treatment is for people suffering from moderate to severe dry eye disease compared to a placebo (a solution that looks the same but has no active ingredients). The trial will take place at multiple locations and will involve participants using the eye drops for a set period, followed by an additional year of open-label treatment, meaning everyone will eventually receive the CAM-101 treatment.

To join the study, participants must be at least 18 years old (or 20 in India) and have been experiencing dry eye symptoms for the past six months. They should also meet specific criteria regarding eye health and be willing to stop using certain other eye treatments during the trial. Participants will need to attend follow-up visits to track their progress. It's essential for anyone interested to discuss their eligibility and any concerns with their doctor before considering participation.

• • 2. Having a self-reported history of dry eye disease within the past 6 months.
• • 3. NEI Corneal Fluorescein Staining Score in at least one eye at screening and at Day 0 (pre-randomization) that is ≥ 6≥ 6 (total score)as determined by the investigator.
• • 4. Visual Analog Scale (VAS) Symptom Index-Eye Dryness/Eye Discomfort total score (pre-dose) that is ≥ 40 points at screening and at Day 0 (pre-randomization).
• • 5. Willingness to have both the right and left eyes treated in the study.

• • 7. Be able to demonstrate ability to use study medication bottle; this can be documented on study bottle used during washout period.
• 8. Female subjects must be either: (1) of non-childbearing potential; or, (2) of childbearing potential and using an acceptable method of birth control with a negative pregnancy test :
• • 1. Females of Non-childbearing Potential: Surgically sterilized (e.g., hysterectomy or bilateral oophorectomy) prior to screening; or, post-menopausal (i.e., no menstrual bleeding for at least 1 year prior to screening; or with a negative pregnancy test if less than 1 year post-menopausal).
• • 2. Females of Childbearing Potential: Must agree to use a highly effective acceptable form of birth control (e.g., established hormonal birth control, or double barrier method: intrauterine device plus condom or spermicidal gel plus condom) from 21 days prior to dosing until 7 days after dosing.
• • 9. Providing written Informed Consent consistent with privacy language as per national regulations (e.g., HIPAA authorization) with signature obtained from the subject or legally authorized representative prior to the performance of any study related procedures (including withdrawal of prohibited medication.
• • 10. Willingness and ability to comply with schedule for follow-up visits and postoperative evaluations.
• • -
• Exclusion Criteria:
• * Subjects who meet any of the following exclusion criteria for one or both eyes at screening will not be enrolled in the study. Subjects who meet any of the following exclusion criteria for one or both eyes on Day 0 will not be randomized and will be withdrawn from the study as screen failures:
• • 1. Any abnormal lid anatomy or blinking function in either eye.
• 2. Using any topical ocular treatment other than the following medications:
• • a. Artificial Tears: Preservative-free artificial tears may be used as needed before and/or during the study. Whenever practicable, the same brand of artificial tears should be used throughout the study and its use documented in the patient diary throughout study participation.
• 3. Previous ocular surgery of any type (including lacrimal, corneal and trauma), except:
• • 1. Non-refractive laser eye surgery of any type in either eye performed more than 3 months before screening is permitted.
• • 2. Refractive surgery in either eye performed more than 6 months before screening is permitted.
• • 3. Cataract surgery in either eye performed more than 3 months before screening is permitted
• 4. Any ocular anomaly that, in the investigator's opinion, interferes with the ocular surface, including:
• • 1. Active ocular herpes simplex virus infection
• • 2. Recurrent corneal erosion
• • 3. Symptomatic epithelial basement membrane dystrophy
• • 4. Mucus fishing syndrome
• • 5. Giant papillary conjunctivitis
• • 6. Post-radiation keratitis
• • 7. Stevens-Johnson syndrome
• • 8. Corneal ulcer
• • 9. Abnormalities of the nasolacrimal drainage system
• • 10. Chemical injury
• • 11. Diagnosed significant anterior blepharitis and/or progressive pterygium
• 5. Current history of ocular infection (viral, bacterial, fungal), disease or inflammation (e.g., uveitis) not associated with dry eye, unless the disorder or disease is, in the investigator's opinion:
• • 1. Stable for at least 3 months before the Screening Visit; and,
• • 2. Not likely to impact or possibly interfere with the interpretation of study results.
• • 6. Subjects with a current intraocular infection or with any other current eye or systemic condition (e.g., severe endothelial corneal dystrophy) that, in the investigator's opinion, would interfere with the dry eye evaluation or treatment, or for which the potential benefits of CAM-101 do not outweigh the risks.
• • 7. History of ocular allergy (including seasonal conjunctivitis) or chronic conjunctivitis other than that secondary to dry eye.
• • 8. Known hypersensitivity to the components of CAM-101 or the vehicle control (fibrinogen-depleted human platelet lysate; Plasma-Lyte A).
• • 9. Known hypersensitivity to one of the procedural medications (e.g., proparacaine, fluorescein) unless a suitable alternative medication is available.
• • 10. Inability to refrain from contact lens wear during the study, including the vehicle control run-in period.
• • 11. Anticipated need for temporary or permanent punctum plugs during the study. (If punctum plugs have been in place for at least 4 weeks prior to the screening visit, the plugs are allowed to remain in place during the study. ) Patients must remain symptomatic for DED post punctal plug insertion.
• • 12. Any ocular disease or ocular condition not stabilized within 1 month (30 days) before the screening visit.
• • 13. Any clinically significant systemic disease or condition that is inadequately controlled (e.g., diabetes, thyroid disease, autoimmune disease) or not stabilized within 4 weeks before the screening visit.
• • 14. Inability or unwillingness to discontinue use of autologous serum eye drops or platelet rich plasma eye drops during the 2-week run-in period and throughout the remainder of the study.
• • 15. Female subjects who are pregnant or lactating or plan to become pregnant during the course of the study.
• • 16. Subjects not under legal guardianship who, in the investigator's opinion, lack the mental capacity to provide written informed consent for study participation.
