Objective

Registered study purpose

“This trial is a randomized study to evaluate the Bimatoprost Implant System used in combination with the SpyGlass IOL to Timolol Ophthalmic Solution in participants with mild to moderate open-angle glaucoma or ocular hypertension undergoing cataract surgery.” (opens the source at this quote in a new tab)

Primary objective of the Phase 3 program

“The primary objective of the Phase 3 program is to evaluate and compare the safety, IOP-lowering efficacy, and BCDVA efficacy of the BIM-IOL System versus control in participants with OAG or OHT undergoing cataract surgery.” (opens the source at this quote in a new tab)

“We plan to complete Phase 3 enrollment by 2027 and report 12 month data in 2028 and 24 month data in 2029.” (opens the source at this quote in a new tab)

First randomization and enrollment status

“The two registrational Phase 3 trials, SGP-005 and SGP-006, are designed to demonstrate non-inferiority of the BIM-IOL System to a state-of-the-art commercial IOL with twice-daily topical timolol. SpyGlass Pharma continues to expect that both trials will complete enrollment in 2027.” (opens the source at this quote in a new tab)

Phase III program design as announced

“The Phase III clinical trial program consists of two prospective, multicenter, randomized, masked, controlled clinical trials, SGP-005 and SGP-006, evaluating the efficacy and safety of the BIM-IOL System in patients with OAG or OHT undergoing cataract surgery. Each trial is expected to enroll approximately 400 participants and is designed to demonstrate non-inferiority of the BIM-IOL System to a standard of care commercial intraocular lens (IOL) with twice-daily administration of timolol eye drops.” (opens the source at this quote in a new tab)
“Participants will be monitored for up to 36 months to evaluate long-term safety, efficacy, and durability.” (opens the source at this quote in a new tab)

Protocol changes from the Phase 1/2 trial

“Key changes include tightening the baseline IOP range, enrolling patients on up to two IOP-lowering medications, tailoring washout periods based on drug class pharmacokinetics, and standardizing IOP measurement timing.” (opens the source at this quote in a new tab)

“Uncontrolled systemic disease” (opens the source at this quote in a new tab)
“History of incisional/refractive corneal surgery” (opens the source at this quote in a new tab)
“Any glaucoma diagnosis other than OHT, open-angle, pseudoexfoliative, or pigmentary glaucoma” (opens the source at this quote in a new tab)

“Other ocular diseases, pathology, or conditions” (opens the source at this quote in a new tab)

Baseline medication burden permitted

“Each prospective, multicenter, randomized, masked, controlled Phase 3 clinical trial evaluates the safety and efficacy of the BIM-IOL System (78 mcg) in patients with OAG or OHT and a concomitant cataract, who are taking up to two IOP-lowering medications.” (opens the source at this quote in a new tab)

Treatment

Registered arms and interventions

Arm	Arm type	Quoted intervention description
“Bimatoprost Implant System / IOL Combination”	“Experimental”	“Bimatoprost Implant System used in combination with the SpyGlass IOL”; “SpyGlass Intraocular Lens”
“Timolol Maleate Ophthalmic Solution 0.5%”	“Active Comparator”	“Timolol Maleate Ophthalmic Solution, 0.5% BID”; “Commercially Available Aspheric Monofocal Non-Yellow Chromophore Intraocular Lens”

Randomization ratio and washout

“Enrolled patients will be randomized into two groups at a ratio of 1:1 to receive the BIM-IOL System (78 mcg) or a commercially available monofocal IOL with twice-daily administration of timolol maleate 0.5%, as the control group. Enrolled patients who meet the surgical eligibility criteria will receive cataract surgery in one eye (the study eye) after receiving a baseline washout of all IOP-lowering medications.” (opens the source at this quote in a new tab)

Study outcomes

Rationale for using time-matched mean IOP change from baseline and BCDVA of 20/40 or better as the co-primary endpoints

Registered primary and secondary outcomes

Outcome type	Measure	Description	Time frame
Primary	“Mean IOP Reduction from Baseline (mmHg)”	“Time-matched mean IOP change from Baseline in the study eyes at all the individual IOP timepoints”	“Weeks 2 and 6, and Month 3”
Primary	“BCDVA 20/40 or better”	“Study eyes achieving best corrected distance visual acuity (BCDVA) of 20/40 or better”	“Month 6”
Secondary	“Mean IOP Reduction from Baseline (mmHg)”	“Time matched mean IOP reduction from Baseline (mmHg) in the study eyes at all the individual IOP timepoints”	“Month 6, 9 and 12”

Co-primary and secondary endpoints as announced

“The co-primary endpoints are the time-matched change in mean IOP from baseline, as well as the proportion of patients achieving best corrected distance visual acuity (BCDVA) of 20/40 or better. The studies will also measure change in mean IOP, time to postoperative introduction of IOP-lowering medications, and number of IOP-lowering medications introduced postoperatively.” (opens the source at this quote in a new tab)

Co-primary endpoint timing described in the Form 10-K

“The co-primary endpoints are (1) the time-matched mean IOP change from baseline at 8 and 10 a.m. at two and six weeks and three months and (2) BCDVA of 20/40 or better at 12 months.” (opens the source at this quote in a new tab)

Rationale for IOP as the efficacy endpoint

“The reduction of IOP is currently the only known modifiable risk factor that has been borne out by large randomized controlled clinical trials to reduce both the risk of developing glaucoma and the progression of existing disease” (opens the source at this quote in a new tab)

Summary

SGP-006 has the same registered design, eligibility criteria, arms, and outcomes as SGP-005 and was recruiting at the most recent sponsor update, with enrollment completion expected in 2027; no results are available. The registry start date (October 28, 2025) is recorded as estimated, and the record lists one U.S. site. As for SGP-005, the registry lists the BCDVA co-primary endpoint at Month 6 while the sponsor's Form 10-K states 12 months, the active comparator is twice-daily timolol 0.5% with a commercial monofocal IOL, and no noninferiority margin or statistical analysis plan has been published.
