Intervention model description: Randomized, double-masked, placebo (vehicle)-controlled study evaluating the efficacy and safety of two doses of OCS-01 compared to vehicle
Primary purpose: TREATMENT

Brief summary: The DX-216 trial is a randomized, double-masked, placebo (vehicle)-controlled study evaluating the efficacy and safety of two doses of OCS-01 compared to vehicle in the treatment of inflammation and pain following cataract surgery. The primary objective is to evaluate the efficacy and safety of OCS-01 compared to placebo and the secondary objective is to evaluate the optimal dosing frequency (once a day \[QD\] or twice a day \[BID\]).

Detailed description: This is a multi-center, randomized, double-masked, placebo (vehicle)-controlled study, designed to evaluate the efficacy and safety of OCS-01 ophthalmic suspension (QD versus BID) compared to placebo in treating inflammation and pain following cataract surgery. Subjects will be randomized 1:1:1 to receive OCS-01 QD, OCS-01 BID, or placebo BID. Subjects will dose 1 drop in the study eye BID for 14 days, beginning 1 day post-surgery in the operated eye. The study will last up to 24 days, including a follow-up visit at Visit 7 (Day 22 ± 2).

Eligibility criteria: Inclusion Criteria:

1. Provide written informed consent, approved by the appropriate ethics committee;
2. Be able to comply with the study requirements and visit schedule;
3. Be at least 18 years of age of either sex or any race;
4. Be planning to undergo unilateral cataract extraction via phacoemulsification and PCIOL implantation in the study eye;
5. Have an anterior chamber cell score ≥ 2 at Visit 2 (Day 1 \[18 to 30 hours post-uncomplicated cataract surgery without vitreous loss\]);
6. Have a pin-hole visual acuity (VA) without any other correction \> 20 letters (approximately 20/400) in the operative eye and \> 35 letters (approximately 20/200) in the fellow eye as measured using an Early Treatment for Diabetic Retinopathy Study (ETDRS) chart at Visit 1 (Day -1 to Day -28 \[prior to surgery\]);
7. Have a negative urine pregnancy test at Visit 1 (Day -1 to Day -28 \[prior to surgery\]),

Exclusion Criteria:

1. Have a known sensitivity or allergy to dexamethasone, corticosteroids, or any of the study medication's components;
2. Be monocular;
3. Have any intraocular inflammation (e.g. white blood cells or flare) present in either eye at the Visit 1 (Day -1 to Day -28 \[prior to surgery\]) slit lamp examination;
4. Have a score \> 0 on the Ocular Pain Assessment at Visit 1 (Day -1 to Day -28 \[prior to surgery\]) in the study eye;
5. Use anti-inflammatory agents, analgesics/pain relievers (including opioids, narcotics, and other pain medications), or immunomodulating agents, systemically or in either eye, and/or use medications for benign prostatic hyperplasia (BPH), from the washout period through the duration of the study.

Primary outcomes:
measure: Number of Subjects With Absence of Anterior Chamber Cells (i.e. Score of '0')
timeFrame: at Day 15 (visit 6)
measure: Number of Subjects With Absence of Ocular Pain (i.e. Score of '0')
timeFrame: at Day 4 (visit 4)
