Clobetasol Propionate Ophthalmic Nanoemulsion 0.05% for the Treatment of Inflammation and Pain Associated With Cataract Surgery (CLOSE-1)

Inclusion Criteria: 1. Male or female, age 18 years or older on day of consent 2. Participants with routine unilateral cataract surgery on the day prior to study randomization 3. Participants with at least 5 cells in anterior chamber on the first day after surgery (at Baseline visit) 4. Willing and able to understand and provide written informed consent form (ICF) (at Screening visit) 5. Women who satisfy one of the following: 1. Are of child-bearing potential who are not pregnant or lactating and who are either abstinent or sexually active on an acceptable method of birth control (methods that can achieve a failure rate of less than 1% per year when used consistently and correctly, like hormonal contraception (oral pills, implantable device, or skin patch), intrauterine device, bilateral tubal occlusion, or double barrier) for at least 4 weeks prior to Baseline visit and throughout the study (i.e., until Day 29), OR 2. Are post-menopausal (have had no menstrual cycle for at least one year prior to Screening visit) or have undergone a sterilization procedure (bilateral tubal ligation, hysterectomy, hysterectomy with unilateral or bilateral oophorectomy or bilateral oophorectomy) at least 6 months prior to Screening visit Exclusion Criteria: 1. Systemic administration of any corticosteroid or immunosuppressant drugs in the previous 2 weeks prior to the first instillation of the investigational medical product (IMP) 2. Periocular injection in the study eye of any corticosteroid solution within 4 weeks prior to the first instillation of the IMP, or of any corticosteroid depot within 2 months prior to the first instillation of the investigational medical product (Ozurdex® \[dexamethasone\]: within prior 6 months; Iluvien® \[fluocinolone\]: within prior 36 months) 3. Instillation of any topical ocular corticosteroid, non-steroidal antiinflammatory drug (NSAID), mast cells stabilizers, antihistamines or decongestants within 2 weeks prior to the first instillation of the IMP, except pre-surgical and/or surgical administration of 1 drop of a topical NSAID or corticosteroid, at the investigator discretion 4. Prescription of any topical ocular medication, except preservative-free antibiotics for prophylactic purposes 5. Any history of glaucoma or ocular hypertension in the study eye 6. History or presence of endogenous uveitis 7. Any current corneal abrasion or ulceration 8. Any confirmed or suspected active viral, bacterial, or fungal keratoconjunctival disease 9. Known hypersensitivity or contraindication to the study drug or any of its components 10. History of steroid-related intraocular pressure (IOP) increase 11. Previous surgery in the last 4 weeks prior to the Screening visit or new surgery scheduled to be performed before the end of the study period on the contralateral eye 12. Presence of ocular hemorrhage which interferes with the evaluation of post-surgery inflammation 13. Presence of intraoperative complications during the cataract surgical procedure that may increase post-operative inflammation; this includes, in particular, participants with ocular hemorrhage, floppy iris syndrome, increased IOP (≥24 mmHg), posterior capsule rupture and injections of gas into the vitreous body 14. Increased cumulative dissipated energy value during phacoemulsification (increased energy used for phacoemulsification exert additional stress on iris and other anterior chamber structures and may generate excessive inflammation) 15. Presence of zonular dialysis (rupture of zonular fibers that attach lens to the ciliar body which may lead to partial luxation of the lens / lens capsule and is a serious complication of cataract surgery) 16. Presence of Fuchs´ endothelial dystrophy (loss of endothelial cells that may result in chronic corneal edema after cataract surgery especially if high energy was used during phacoemulsification) 17. Presence of cornea guttata 18. Pupil dilation lower than 4.5 mm 19. Presence of lower lacrimal duct obstruction and/or history of infectious dacryocystitis 20. Presence of IOP ≥24 mmHg at Baseline visit 21. Participation in any study of an investigational topical or systemic new drug or device within 30 days prior to the Screening visit, or at any time during the study 22. Prior participation in the study described in this protocol, unless participant was not randomized 23. In the opinion of the investigator or study coordinator, be unwilling or unable to comply with study protocol or unable to successfully instill eye drops 24. Disease, condition (including monocular participants), or disorder that in the judgement of investigator could confound study assessments or limit compliance to study protocol
