-The patient is scheduled for in-patient hospitalization including elective surgery, during the study.
-The patient has a clinically significant, uncontrolled medical condition that, in the opinion of the investigator, would put the safety of the subject at risk through participation, or which would affect the efficacy or safety analysis if the condition exacerbated during the study, or that may significantly interfere with study compliance, including all prescribed evaluations and follow-up activities.
-The patient, in the opinion of the investigator, is unable to adhere to the requirements of the study or unable to undergo study assessments (eg, has contraindications to pupillary dilation or unable to undergo magnetic resonance imaging (MRI ) [For example: patient’s weight exceeds weight capacity of the MRI, ferromagnetic metal prostheses, aneurysm clips, severe claustrophobia, large abdominal/back tattoos, etc]).
-Any country-related specific regulation that would prevent the patient from entering the study.
-The patients did not adhere to treatment (<70% compliance rate) in the run-in.
-The patient has, according to World Health Organization (WHO) Grading, a cortical cataract >onequarter of the lens circumference (Grade cortical cataract-2 [COR-2]) or a posterior subcapsular cataract >2 mm (Grade posterior subcapsular cataract-2 [PSC-2]). Patients with nuclear cataracts will not be excluded.
-The patient is currently receiving potentially cataractogenic medications, including a chronic regimen (more frequently than every 2 weeks) of any route of corticosteroids (including medium and high potency topical steroids) or any medication that may cause cataract, according to the Prescribing Information.
-The patient has received strong or moderate inducers or inhibitors of CYP3A4 within 14 days or 5 half-lives, whichever is longer, prior to randomization.
