Outcome Measures

Primary Outcomes (1)

• Number of Participants With Treatment Emergent Adverse Event (TEAE)

  An adverse event (AE) is any untoward medical occurrence in a clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. TEAEs were defined as AEs with a start date on or after the first dose of double-blind investigational product or a start date before the date of the first dose of double-blind investigational product that increased in severity or after the date of the first dose.

  From start of study drug administration up to follow-up (Day 88)

Secondary Outcomes (1)

• Change From Baseline in Intra Ocular Pressure (IOP) at Day 29

  Baseline, Day 29

Study Arms (2)

SHP639 Ophthalmic Solution Arm (n=60)

EXPERIMENTAL

Participants are divided into groups called cohorts. There will be approximately 12 cohorts, each consisting of 7 participants. In each cohort 5 out of 7 participants will be assigned a specified concentration of SHP639 (0.1%, 0.3%, or 0.6%) ophthalmic solution and a specific dosing schedule (the study participants will be instructed to insill the study drug one, two, three, or four times a day) in both eyes during the study.

Drug: SHP639 (n=60)

Vehicle Ophthalmic Arm (n=24)

PLACEBO COMPARATOR

In each cohort 2 out of 7 participants will be assigned a placebo ophthalmic solution matched to 0.1%, 0.3%, and 0.6% SHP639 ophthalmic solution and specific dosing schedule (the study participants will be instructed to instill the study drug one, two, three, or four times a day) in both eyes during the study.

Drug: Placebo Comparator (n=24)

Interventions

Eligibility Criteria

• Age: 18 Years - 90 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Participants must provide written, signed and dated informed consent to participate in the study in accordance with the International Council for Harmonisation (ICH) Good Clinical Practice (GCP) Guideline E6(R1) and applicable regulations, before completing any study-related procedures.
• Participants must have ocular hypertension (OHT) or stable early primary open-angle glaucoma (POAG) in both eyes with acceptable Humphrey visual fields (HVF). Early POAG for this protocol is defined as healthy appearing anterior chamber angles (Shaffer classification system grade 3 or 4) and focal and/or generalized thinning of the optic disc rim characteristic of glaucomatous disease. An acceptable HVF must have been performed within approximately one year of screening, have a false-positive rate of 25 percent (%) maximum, false-negative rate of 25% maximum, and fixation loss rate of 33% maximum, and mean deviation of no worse than -6.00 decibels (dB).
• On Day -1, participants must have a mean IOP of greater than or equal to (\>=) 24 millimeter of mercury (mmHg) at 8:00 AM and a mean IOP of \>= 22 mmHg at 10:00 AM in at least 1 eye, with an IOP difference of less than (\<) 4 mmHg between eyes at both of these time points. If only 1 eye meets this criterion, then it will be the designated study eye for pharmacodynamic analysis; this eye will also be used for dosing in Cohort A single-dose treatment period (SDTP).
• Participants must have a best-corrected visual acuity (BCVA) in both eyes of 65 letters on the Early Treatment Diabetic Retinopathy Study chart (Snellen equivalent approximately \[∼\] 20/60) or better at the screening and baseline assessments.
• Participants must be males or females who are non-pregnant and non-lactating at screening (negative serum beta-human chorionic gonadotropin \[beta-hCG\]); if sexually active during the study, they must agree to comply with the applicable contraceptive requirements throughout the study period and for 60 days following the last dose of investigational product.
• Participants must have a satisfactory medical assessment with no clinically significant or relevant abnormalities as determined by medical history, physical examination, and clinical and laboratory evaluation (hematology, biochemistry, urinalysis) as assessed by the investigator.
• Participants must understand and be able, willing, and likely to fully comply with study procedures and restrictions.
• Participants must be non-smokers or have had stable use of tobacco or nicotine-containing products for a 3-month period before signing the informed consent form (ICF).
• Participants who drink alcohol must have had stable use of alcohol for a 3-month period before signing the ICF.

You may not qualify if:

• Participant has an anatomically narrow angle, synechiae or evidence of prior inflammation, angle closure glaucoma, normal tension glaucoma, pseudoexfoliation syndrome or pigmentary dispersion syndrome with or without glaucoma, or secondary glaucoma.
• Participant has corneal endothelial cell counts of less than 2000 cells per millimeter\^2 (measured by noncontact specular microscopy) at the screening or baseline assessments.
• Participant has central corneal thickness less than 500 micrometer (mcm) or greater than 620 mcm at the screening or baseline assessments.
• Participant has IOP greater than 32 mmHg in either eye before randomization.
• Participant has used topical ocular hypotensive medications as follows: prostaglandin analogs, beta-adrenoceptor antagonists, alpha-adrenergic agonists, or epinephrine-related medications within 4 weeks before the first dose of investigational product; or pilocarpine or carbonic anhydrase inhibitors within 7 days before the first dose of investigational product.
• Participant has a history of angle closure, ocular surgery, microinvasive glaucoma surgery device insertion, or laser surgery, except for the following procedures, which are allowed: uncomplicated cataract surgery, laser peripheral iridotomy with resultant angle of Shaffer grade 3 or 4, and postcataract neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser posterior capsulotomy. Cataract surgery and other procedures must have occurred a minimum of 3 months before randomization.
• Participant has a history of significant ocular trauma or ocular disease including but not limited to moderate to severe dry eye disease that requires chronic treatment or punctal plugs.
• Participant has evidence of ocular infection, inflammation, degeneration, or dystrophy at the screening or baseline assessments, including but not limited to moderate to severe blepharitis (mild blepharitis is allowed), conjunctivitis (allergic or infectious), corneal dystrophy (epithelial, stromal, or endothelial), corneal haze of grade 1 or greater based on the Hwang Grading Scale of Corneal Haze, corneal opacities, keratitis, uveitis, or vitritis.
• Participant has retinal disease including but not limited to: moderate or severe non-proliferative diabetic retinopathy (NPDR) (early NPDR is allowed), proliferative diabetic retinopathy, intermediate or advanced dry age-related macular degeneration (AMD) (early dry AMD is allowed), all geographic atrophy, or all wet AMD.
• Participant has any non-glaucomatous optic neuropathy or other significant non-glaucomatous ocular disease that is likely to affect visual function.
• Participant has any corneal or ocular surface pathology in either eye that prevents proper IOP measurement, pachymetry, or other study data collection procedures.
• Participant has had changes to their existing prescription medication regimen for chronic disease, including those medicines that affect IOP, within 14 days or 5 half-lives before screening, whichever is longer.
• Participant has started any new prescription drug medication for chronic disease, including those medicines that affect IOP, within 14 days or 5 half-lives before screening, whichever is longer.
• Participant has a history of corticosteroid use within 3 months before randomization, except for non-periocular dermatologic use, which is allowed.
• Participant has used belladonna alkaloids (scopolamine, hyoscamine, atropine) within 7 days prior to randomization, cannabinoids or opioids within 28 days before randomization, or B-type natriuretic peptides within the past year before randomization; or a participant has an anticipated need for any of the aforementioned drugs/drug categories during the study.
