iDose TR is a first-of-its-kind, long-duration, intracameral procedural pharmaceutical therapy designed to continuously deliver 24/7 therapeutic levels of a proprietary formulation of travoprost inside the eye for extended periods of time. iDose TR is intended to improve the standard of care by addressing the ubiquitous patient non-compliance issues and chronic side effects associated with topical glaucoma medications.
'The FDA approval of iDose TR represents a significant milestone for
'With the next generation of procedural pharmaceutical solutions for glaucoma such as iDose TR, we now have a new tool that will confront the standard legacy practice of relying on topical drops, which are known to cause uncomfortable side effects and present a myriad of challenges such as treatment adherence, complex dosing regimens, and difficulty with self-administration,' said
The FDA approval is based on results from two prospective, randomized, multicenter, double-masked, Phase 3 pivotal trials (GC-010 and GC-012) designed to compare the safety and efficacy of a single administration of one of two iDose TR models with different travoprost release rates (referred to as the fast- and slow-release iDose TR models, respectively) to topical timolol ophthalmic solution, 0.5% BID (twice a day), in reducing IOP in subjects with open-angle glaucoma or ocular hypertension. In total, the Phase 3 trials randomized 1,150 subjects across 89 clinical sites. The FDA approval and Phase 3 data referenced below is for the slow-release iDose TR model, consistent with the company's NDA submission and commercialization plans.
Both Phase 3 trials successfully achieved the pre-specified primary efficacy endpoints through 3 months and demonstrated a favorable tolerability and safety profile through 12 months. IOP reductions from baseline over the first 3 months were 6.6-8.4 mmHg in the iDose TR arm, versus 6.5-7.7 mmHg in the timolol control arm (mmHg range represents IOP reduction means across the six
At 12 months, 81% of iDose TR subjects were completely free of IOP-lowering topical medications across both trials. In both trials, iDose TR demonstrated excellent tolerability and subject retention with 98% of iDose TR subjects continuing in the trial at 12 months, versus 95% of timolol control subjects. In controlled studies, the most common ocular adverse reactions reported in 2% to 6% of iDose TR patients were increases in intraocular pressure, iritis, dry eye, and visual field defects, most of which were mild and transient in nature.
iDose TR is also supported by positive results from a Phase 2b clinical trial, which were recently highlighted in a peer-reviewed publication in Drugs (link here). The study authors concluded, 'The travoprost intraocular implant demonstrated robust IOP-lowering and substantially reduced topical IOP-lowering medication burden for up to 36 months following a single administration, while maintaining a favorable safety profile.'

About iDoseTR
iDoseTR (travoprost intracameral implant) is a long duration prostaglandin analog approved for a single administration and indicated for the reduction of intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT). Made from medical-grade titanium, iDose TR is implanted through the trabecular meshwork and back wall of Schlemm's canal, directly into scleral tissue. Once implanted, 75 mcg of a novel, preservative-free, proprietary formulation of travoprost continuously elutes into the anterior chamber via membrane-controlled diffusion, allowing for 24/7 release of medication.
