iSTAR Medical Presents Positive Consistent Results for MINIject® Across Three International Glaucoma Trials
Analysis provides further validation of MINIject®’s meaningful and sustained efficacy in open angle glaucoma patients
No safety concerns with corneal endothelial health reported across all three trials
MINIject® delivers positive, consistent results up to two-year follow-up in patients across Central and South America, Asia and Europe
WAVRE, Belgium — 8 June 2022: iSTAR Medical, a medtech company delivering breakthrough eye care solutions to patients, presented two-year safety and efficacy results in a meta-analysis of its STAR-I, STAR-II and STAR-III clinical trials for MINIject® at the 15th European Glaucoma Society (EGS) Congress in Athens. MINIject® is the only commercially available supraciliary minimally invasive glaucoma surgery (MIGS) device.
The two-year results indicated sustained, meaningful efficacy and favourable safety outcomes in patients with primary open-angle glaucoma. In all three trials, MINIject® met all endpoints, which included a significant reduction in both intraocular pressure (IOP) as well as hypotensive medication-use. Furthermore, no safety concerns regarding corneal endothelial health were raised across all three trials, a pivotal factor in long-term safety.
Data from the three completed, prospective, open, international, single-arm trials1 in patients with mild-to-moderate, primary open-angle glaucoma, and whose medication was no longer effective, were pooled in a meta-analysis. MINIject® was implanted in a standalone procedure across 11 sites in Central and South America, Asia and Europe.
Results from 66 patients implanted with MINIject® across the three trials demonstrated a significant and meaningful 39% reduction in IOP from medicated pre-procedure IOP of 23.8mmHg down to 14.4mmHg at two-year follow-up. The IOP level and reduction were similar at all semi-annual follow-up visits until two years, representing a stable result over time. Additionally, 38% of patients were medication-free at two years, and an IOP of ≤18 mmHg was achieved in 85% of patients. MINIject® also showed no safety concerns with corneal endothelial health at two-year follow-up.
MINIject® is currently being investigated in iSTAR Medical’s pivotal US trial, STAR-V, where enrollment continues as planned.
Prof. Dr Antonio Fea, Università degli Studi di Torino, Turin, Italy, and presenter of the data at the 15th EGS Congress, said: “It is highly encouraging to see consistent efficacy and safety results for MINIject in different regions and across three trials. The supraciliary space has previously been demonstrated to be one of the most efficacious targets for the reduction of eye pressure, and the potential of a new bleb-free MIGS approach with strong efficacy and good safety data represents a highly compelling treatment option for glaucoma patients.”
Michel Vanbrabant, CEO of iSTAR Medical, commented: “This meta-analysis of our three STAR trials at two years has clearly strengthened the growing evidence for MINIject as a safe, standalone procedure. With all endpoints met, the results demonstrate MINIject’s meaningful and stable efficacy over a two-year follow-up period in a sizeable patient population spanning several regions throughout the world, and without compromising patient safety. We look forward to providing further supporting safety and efficacy data from the long-term, follow-up trial, STAR-GLOBAL.”

MINIject® is iSTAR Medical’s innovative MIGS device for patients with primary open-angle glaucoma. MINIject® combines the distinctive porous structure of its proprietary STAR material with the power offered by the supraciliary space. As a result, it is designed to enhance natural fluid outflow, reducing intraocular pressure (IOP) and the need for medication, while bio-integrating with surrounding tissue, limiting inflammation, fibrosis and subsequent complications.
Glaucoma is a progressive disease affecting over 100 million people globally, of which primary open-angle glaucoma is the most common form.1,2 IOP reduction, through medication or surgery, helps delay disease progression.3 Medication is generally the first line treatment, but the progressive addition of multiple drops can burden patients with side effects, compliance challenges and costs.1,3 Invasive surgery can present risks with irreversible complications and often requires long-term patient management.1,3 MIGS is the most promising and fastest-growing glaucoma therapy due to its enhanced safety profile.1 We believe MINIject® may become a leading MIGS device with its promising long-term efficacy and safety.
