MINIject S+ for Open Angle Glaucoma in Adults

Official title: A Multi-center, Prospective, Cohort Expansion Clinical Study Evaluating the Safety, Usability, Implantation Accuracy and Efficacy of MINIject S+ in Subjects With Open Angle Glaucoma (STAR VII Study)

Run by iSTAR Medical · NCT07009236 · Data updated 2026-11-12

This study tests MINIject S+ implants in adults with open angle glaucoma to see if it works well and is safe using different insertion tools, with later expansion to more patients undergoing combined glaucoma and cataract surgery.

Is this trial a fit for you?

Likely a good fit

Adults 20 years or older with open angle glaucoma and insufficient control on at least one topical hypotensive medication, with adequate visual acuity, and suitable anterior segment anatomy.

Probably not a fit

Patients with unsuitable angle anatomy, inability to tolerate the procedure, or those not meeting visual acuity criteria may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter, international study in two parts. Part 1 compares three insertion tools for placing MINIject S+ implants in adults with open angle glaucoma, with blinding of subjects and central readers to the tool used. Part 2 expands to a larger population undergoing combined glaucoma and cataract surgery, using the selected insertion tool. The study focuses on safety and efficacy of the MIGS device as an add-on therapy for patients not adequately controlled on standard medications.

Why it matters

Potential benefit: If successful, MINIject S+ could offer a safer, effective option to reduce eye pressure in open angle glaucoma and potentially reduce reliance on daily eye drops.

How similar studies have gone: Prior MIGS approaches have shown safety and potential intraocular pressure benefits, but this specific tool-variation and first-in-man design are novel for MINIject S+ in this context.

Inclusion criteria

1. Males or females, 20 years of age or older
2. Diagnosis of open angle glaucoma (OAG) in the study eye
3. Iridocorneal angle grade 3 (open, 20-35 degrees) or grade 4 (wide open, 35-45 degrees) according to Shaffer Angle Grading System in all quadrants of the study eye. (For subject's undergoing combined cataract extraction (with IOL implantation) with MINIject implantation, a grade 2 angle is acceptable prior to cataract surgery so long is the angle becomes grade 3 or greater prior to MINIject implantation).
4. Glaucoma not adequately controlled with at least one topical hypotensive medication(s), unless the subject has an allergy / intolerance to a medication or inability to consistently access medication. Examples include but are not limited to prostaglandins, beta blockers, carbonic anhydrase inhibitors or alpha-2-agonists
5. Minimal visual acuity in the study eye must be 35 letters EDTRS (20/200) or better and 50 letters ETDRS (20/100) or better in the fellow eye
6. Maximal C/D ratio must be 0.9 in the study eye
7. Subjects must be willing and able to follow study instructions and to return for scheduled study-related examinations
8. Subjects must provide written informed consent prior to any study procedures
9. Part 2 Only: Operable age-related cataract eligible for phacoemulsification surgery with Intraocular Lens (IOL) implantation
10. Part 2 Only: The following intraoperative criteria following the IOL implantation need to be met in order for investigator to proceed with the investigational device placement:

    1. Capsulorhexis is intact and centered
    2. Posterior capsular bag is intact
    3. The IOL is well-centered in the capsular bag
    4. There is no evidence of zonular dehiscence/rupture
    5. The Anterior Chamber (AC) angle was able to be clearly visualized using direct gonioscopy.

Exclusion criteria

Subjects are not eligible for inclusion in this clinical investigation if one or more of the following criteria are met:

1. Grade 2 (narrow, 20 degrees), grade 1 (extremely narrow, less or equal to 10 degrees) and grade 0 (closed or slit) iridocorneal angle according to Shaffer Angle Grading System in the study eye except for the situation described in inclusion criterion #3.
2. Any eye surgery that was performed \< 90 days before Screening/Baseline visit in the study eye
3. Diagnosis of diabetes mellitus with HbA1C \>7%
4. Known or suspected allergy or hypersensitivity to medical silicone
5. Allergy to fluorescein
6. Corneal opacity or iridocorneal angle not visible through gonioprism in the study eye, preventing correct placement of the implant
7. Central endothelial cell density (ECD) at Screening visit with a mean value \<1900 cells/mm2 or coefficient of variation (CV) of endothelium \>0.45 A variance of 5% less than this cell count is permitted if in the clinical judgement of the Investigator the potential benefit/risk to subject participation is favorable and the central corneal endothelial morphology is characterized as normal by the usual criteria of hexagonality, polymorphism, and polymegathism
8. Anticipated need for ocular surgery or retinal laser procedure in the study eye
9. Anterior chamber anatomic configuration of high risk for development of angle closure glaucoma in the study eye,
10. Pre-existing ocular or systemic pathology that, in the opinion of the investigator (reason to be specified on the case report form), is likely to cause post-operative complications following implantation
11. Central corneal thickness greater than 600 microns
12. Clinically significant degenerative visual disorders that, in the opinion of the investigator, can impact study examinations (e.g. exudative macular degeneration or other retinal disorders)
13. Clinically significant corneal disease (e.g., corneal dystrophy) in the study eye
14. Evidence of crystalline lens subluxation or luxation in the study eye
15. Inability to perform Visual Field (VF) testing in either eye
16. Evidence of vitreous loss in the anterior chamber in the study eye
17. Clinically significant intra-ocular inflammation or infection
18. Presence of silicone oil in the study eye
19. Participation in any study involving a drug or device within the past 3 months and planned participation to any other study during the present study. There is no exclusion period after completion of the present trial
20. Only for women of childbearing potential: positive pregnancy test at Screening/Baseline visit. Pregnant or lactating women
21. Subject is under tutorship or trusteeship
22. Subject has a condition such that his / her ability to provide personal informed consent is compromised
23. Diagnosis of cataract in the study eye that is not age-related e.g., traumatic, inflammatory or resulting from diabetes in the study eye
24. Unable to discontinue anticoagulant/antiplatelet therapy (i.e. acetylsalicylic acid, coumadin, heparin, apixaban, etc.) for the surgical procedure. The amount of washout and when to restart therapy after surgery is at the Principal Investigator's discretion and may be based on literature references (see Annexes) or in consultation with the subject's primary care team.
