OCULAR THERAPEUTIX, INC. Phase 2 data highlight consistent and sustained reductions in Intraocular Pressure (IOP), statistically significant (p<0.0001) through six months, with clinically meaningful reductions of 24-30% achieved with a single PAXTRAVA implant
Generally well tolerated with no impact on corneal health observed
Consistent durability of IOP reduction and implant bioresorption shows potential for repeat dosing without stacking of implants

“Ocular is very pleased to report positive six-month topline results for PAXTRAVA in the Phase 2 glaucoma study. We designed the Phase 2 clinical trial to evaluate PAXTRAVA over several time points that we believe are clinically meaningful, through six months. Observation of IOP reduction as early as the first follow-up visit, at 2 weeks, and demonstration of a 24-30% reduction in mean IOP through six months, with consistent and sustained reductions at each and every timepoint, are at the core of our enthusiasm for these results. That the majority of eyes (81.3%) treated with PAXTRAVA did not require additional IOP lowering therapy through six months further supports the strength of the data,” said
Summary of Data and Findings:
Efficacy: PAXTRAVA 26 µg single implant demonstrated consistent IOP control through 6 months:
- Statistically significant IOP changes from baseline were observed for each and every individual and mean diurnal measurement at Week 2 (M0.5), Week 6 (M1.5), and Week 12 (M3), as well as Months 4.5 and 6 (p<0.0001), although no formal statistical testing was prespecified
- Clinically meaningful mean IOP reduction of ~24-30% from baseline observed over six months
- A majority (81.3%) of treated eyes did not require additional IOP-lowering therapy through 6 months indicating sustained and consistent treatment effects
Safety: PAXTRAVA 26 µg was generally well-tolerated
- No impact on corneal endothelium was observed at 6 months following a single administration
- Majority of adverse events (AEs) were mild in severity and generally resolved with topical medical treatment. Most ocular AEs within 3 days were deemed related to the injection procedure by the investigators. Post injection AEs observed (>3 days post injection procedure) were consistent with the travoprost label. One implant required removal (classified as a serious adverse event), most likely due to a peri-implantation bacterial infection, per investigator
- Consistent bioresorption of the implant coupled with the durable effect seen in the trial suggests redosing would be possible, without the risk of stacking implants
“I have dedicated my career to taking care of people with glaucoma and the evaluation of new therapies. I am enthusiastic about PAXTRAVA because of the positive, durable IOP reductions, accompanied by a good overall safety profile,” said
“We were pleased to observe that PAXTRAVA generally stays in place at the site of implantation and maintains its form, that the majority of implants (64.5%) were significantly or fully bioresorbed at six months and that the implants were not observed to impact the surrounding corneal endothelium. Together, these features could address the compliance challenge of daily eyedrops and enable repeat dosing, without the risk of stacking, critical for the treatment of chronic disease. The totality of these features makes me optimistic about this product candidate.”

Phase 2 Study Overview: The PAXTRAVA Phase 2 study was designed as a randomized, parallel-group, controlled study to evaluate the safety and efficacy of PAXTRAVA in subjects with open-angle glaucoma (“OAG”) or ocular hypertension (“OHT”) and reported together as “glaucoma”, per above. Following a standard medication wash-out, patients were randomized 1:1:1 into one of three dosing groups (5 µg or 26 µg of PAXTRAVA or DURYSTA® (bimatoprost implant)), dosed in ‘the study eye’ and followed for frequent assessments through the six month analysis point. Due to elevations in IOP observed in seven out of the 16 subjects enrolled in the PAXTRAVA 5 μg arm of the trial, the Company closed enrollment in this arm and continued with the PAXTRAVA 26 μg and DURYSTA arms of the trial. Safety and efficacy data presented at ASCRS and reported in this press release are based on the 26 µg dosing group, as a result.
The enrolled subjects had a mean age of 65 years and had been previously treated with a mean of about 1.2 IOP-lowering agents prior to study entry. The treatment groups were well balanced for key demographics and baseline characteristics. The primary efficacy endpoints included measurement of changes in intraocular pressure (IOP) at three diurnal measurements (
Summary of next steps: Seek an end-of-Phase 2 meeting with the FDA to finalize development plans for PAXTRAVA Phase 3 trials and move to a next generation, commercial injector that eases initiation of therapy.
