- Provide written informed consent;
- Be willing and able to comply with all study procedures;
- Have a patient-reported history of dry eye for at least 5 years prior to Visit 1;
- Have a history of use or desire to use eye drops for dry eye symptoms within 6 months of Visit 1;
- Have a best corrected visual acuity (BCVA) of 0.7 logarithm of the minimum angle of resolution (logMAR) or better (Snellen equivalent score of 20/100 or better) in each eye at Visit 1;
- Have an inferior fluorescein corneal staining score \> 1 at both Visits 1 and 2 Pre-CAE®;
- Have an Eye Discomfort from the Visual Analog Scale (VAS) ≥25 at both Visits 1 and 2 Pre-CAE®;
- Report a score of ≥ 2 according to the Ora Calibra® Ocular Discomfort \& 4-Symptom Questionnaire in at least one of the dry eye symptoms at Visits 1 and 2 Pre-CAE®;
- Have a Schirmer's Test score of ≤ 10 mm and ≥ 1 mm at Visits 1 and 2;
- Have a corneal fluorescein staining score of ≥ 2 in any corneal region (inferior, central or superior) according to the Ora Calibra® Corneal and Conjunctival Staining Scale for Grading of Fluorescein Staining in at least one eye at Visits 1 and 2 Pre-CAE®;
- Have a conjunctival redness score ≥ 1 according to the Ora Calibra® Conjunctival Redness for Dry Eye Scale in at least one eye at Visits 1 and 2 Pre-CAE®;
- Demonstrate in the same eye(s) a response to the CAE®at Visits 1 and 2 as defined by:
- Having at least a ≥1 point increase in fluorescein staining in the inferior region in at least one eye following CAE® exposure;
- Reporting an Ocular Discomfort score ≥3 at 2 or more consecutive time points in at least one eye during CAE® exposure (if a subject has an Ocular Discomfort rating of 3 at time = 0 for an eye, s/he must report an Ocular Discomfort rating of 4 for two consecutive measurements for that eye). Note: a subject cannot have an Ocular Discomfort score of 4 at time = 0);
- Have at least one eye, the same eye, satisfy all criteria for 7, 8, 9, 10, 11, 12 and 13 above;
- A negative urine pregnancy test if female of childbearing potential (those who are not surgically sterilized \[bilateral tubal ligation, hysterectomy or bilateral oophorectomy\] or post-menopausal \[12 months after last menses\]) and must use adequate birth control through the study period. For non-sexually active females, abstinence may be regarded as an adequate method of birth control
Exclusion
- Have any clinically significant slit-lamp findings at Visit 1 that may include active blepharitis, meibomian gland dysfunction, lid margin inflammation, or active ocular allergies that require therapeutic treatment, and/or in the opinion of the Investigator may interfere with study parameters;
- Be diagnosed with an ongoing ocular infection (bacterial, viral, or fungal), or active ocular inflammation at Visit 1 or Visit 2;
- Have worn contact lenses within 7 days of Visit 1 or anticipate using contact lenses during the study;
- Have previously had laser-assisted in situ keratomileusis (LASIK) surgery within the last 12 months;
- Have used Restasis®, Xiidra®, Cequa®, or Eysuvis® within 60 days of Visit 1;
- Have had any ocular and/or lid surgeries in the past 6 months or have any planned ocular and/or lid surgeries over the study period;
- Have had any laser procedures (e.g. YAG capsulotomy) in the past 3 months;
- Be using or anticipate using temporary punctal plugs during the study that have not been stable within 30 days of Visit 1;
- Be currently taking any topical ophthalmic prescription (including medications for glaucoma) or over-the-counter solutions, artificial tears, gels or scrubs, and cannot discontinue these medications for the duration of the trial (excluding medications allowed for the conduct of the study); the respective wash-out periods are required for thefollowing medications:
- Ocular, oral or nasal antihistamines: 72 hours prior to Visit 1 and during the study.
- Oral aspirin or aspirin-containing products allowed if dose has been stable over past 30 days prior to Visit 1 and no change in dose is anticipated during the study period
- Corticosteroids or mast cell stabilizers (including ocular): 14 days prior to Visit 1
- Any medication (oral or topical) known to cause ocular drying that has not been administered as a stable dose for at least 30 days prior to Visit 1 and during the study
- All other topical ophthalmic preparations (including artificial tear substitutes) other than the study drops: 72 hours prior to Visit 1
- Have an uncontrolled systemic disease;
- Be a woman who is pregnant, nursing, or planning a pregnancy;
- Be unwilling to submit a urine pregnancy test at Visit 1 and Visit 6 (or early termination visit) if of childbearing potential. Non-childbearing potential is defined as a woman who is permanently sterilized (e.g., bilateral tubal ligation, hysterectomy or bilateral oophorectomy), or is post-menopausal (without menses for 12 consecutive months);
- Be a woman of childbearing potential who is not using an acceptable means of birth control; acceptable methods of contraception include: hormonal - oral, implantable, injectable, or transdermal contraceptives; mechanical - spermicide in conjunction with a barrier such as a diaphragm or condom; intrauterine device; or surgical sterilization of partner. For non-sexually active females, abstinence may be regarded as an adequate method of birth control; however, if the subject becomes sexually active during the study, she must agree to use adequate birth control as defined above for the remainder of the study;
- Have a known allergy and/or sensitivity to the test article or its components;
- Have a condition or be in a situation which the Investigator feels may put the subject at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study;
- Have used an investigational drug or device within 30 days of Visit 1 unless the Investigator or Sponsor deems a washout period of up to 60 days is required;
- Participated in a previous clinical study involving PL9643;
- Be unable or unwilling to follow instructions, including participation in all study assessments and visits.
