A First-in-Human Study of the Efficacy and Safety of MINIject in Patients with Medically Uncontrolled Open-Angle Glaucoma (STAR-I)
Bibliographic record
Abstract
PURPOSE: To describe the safety and efficacy of a novel, supraciliary, microinvasive glaucoma surgery drainage system, MINIject (iSTAR Medical, Wavre, Belgium), in the study. DESIGN: Prospective, multicenter, interventional, single-arm trial. PARTICIPANTS: Twenty-six patients with primary open-angle glaucoma uncontrolled with 1 or more intraocular pressure (IOP)-lowering medications. METHODS: Using an ab interno approach, 25 eyes were implanted successfully in a stand-alone procedure with a 5-mm long device made of biocompatible STAR material, which is soft and flexible silicone in a microporous, network design. Intraocular pressure, medication use, and other ocular parameters were evaluated before surgery, 1 day, 1 and 2 weeks, and 1, 3, and 6 months after surgery. MAIN OUTCOME MEASURES: Intraocular pressure reduction at 6 months compared with baseline analyzed using a paired t test. Safety evaluation entailed tabulation of the nature and frequency of adverse events. RESULTS: Mean baseline diurnal IOP was 23.2 mmHg (standard error, 0.6 mmHg) using a mean ± standard deviation of 2.0±1.1 IOP-lowering medication classes. During the 6-month follow-up period, mean IOP ranged from 10.0-16.3 mmHg (mean reductions, 6.9-13.2 mmHg or 31.0%-56.8%). Six months after surgery, mean diurnal IOP was 14.2 mmHg (standard error, 0.9 mmHg), equivalent to a reduction of 9.0 mmHg or 39.1% (P < 0.0001). The mean ± standard deviation number of IOP-lowering medications was 0.3±0.7. Of 24 patients seen at 6-month follow-up, 21 (87.5%) were medication-free and 23 (95.8%) achieved a minimum 20% IOP reduction from baseline. There were no serious adverse events related to the device or procedure, and no additional glaucoma surgery was required. Frequently reported events included anterior chamber inflammation (n = 8), IOP elevation (n = 6), of which 1 event was an IOP spike per protocol, visual acuity reduction (n = 3), and hyphema (n = 3), all of which resolved. There was no change to mean central or peripheral corneal endothelial cell density. No device-related adverse events were reported. CONCLUSIONS: The MINIject glaucoma drainage system significantly lowered IOP and eliminated the need for medication in most patients 6 months after surgery when implanted in a standalone procedure. There were no serious ocular adverse events.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
