Aerie Pharmaceuticals Reports Positive Roclatan (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005% Phase 3 Topline Efficacy Results

IRVINE, Calif.--(BUSINESS WIRE) May 24, 2017 -- Aerie Pharmaceuticals, Inc. (NASDAQ:AERI), a clinical-stage pharmaceutical company focused on the discovery, development, and commercialization of first-in-class therapies for the treatment of patients with glaucoma and other diseases of the eye, today reported the successful primary efficacy results of the Company's 90-day Phase 3 "Mercury 2" registration trial for its fixed-dose combination product candidate, Roclatan™. The results of Mercury 2 were consistent with the successful 90-day efficacy results from the Mercury 1 trial, a 12-month Phase 3 registration trial for Roclatan™, which reported topline efficacy findings in September 2016. Mercury 2 achieved its primary efficacy endpoint of demonstrating statistical superiority over each of its components, including Aerie product candidate Rhopressa™ (netarsudil ophthalmic solution) 0.02%, and market-leading prostaglandin analogue (PGA) latanoprost, all of which were dosed once daily in the evening. The IOP-lowering effect of Roclatan™ was 1 to 3 mmHg (millimeters of mercury) greater than monotherapy with either latanoprost or Rhopressa™ throughout the duration of the study. The study evaluated patients with maximum baseline intraocular pressures (IOPs) ranging from above 20 to below 36 mmHg. Management will host a conference call with accompanying slides to discuss these results at 5:00 p.m. Eastern Time (ET) today. The accompanying slides are available at Aerie's website,

Roclatan™ Phase 3 Highlights for Mercury 2

  • Roclatan™ dosed once daily achieved the primary efficacy endpoint of demonstrating statistical superiority over both latanoprost and Rhopressa™ at the primary endpoint range of baseline IOPs from above 20 to below 36 mmHg for each of the nine measured time points.
  • IOPs were measured at 8 a.m., 10 a.m., and 4 p.m. at week 2, week 6, and day 90. Roclatan™ IOP lowering exceeded that of latanoprost in a range of 1.5 to 2.4 mmHg for an average of 1.8 mmHg, and exceeded Rhopressa™ IOP lowering in a range of 2.2 to 3.3 mmHg for an average of 2.7 mmHg. Efficacy levels were consistent across the 90-day period for all arms in the study.
  • Roclatan™ reduced mean diurnal IOPs to 16 mmHg or lower in 56 percent of patients, a significantly higher percentage than observed in the two comparator arms.
  • Discontinuation rates for the 90-day period for Roclatan™ and Rhopressa™ were approximately 10 percent for each product candidate, representing the lowest discontinuation rates experienced across all Phase 3 trials of Roclatan™ and Rhopressa™.
  • The most common Roclatan™ adverse event was hyperemia, or eye redness, which was reported in nearly 55 percent of patients, was sporadic, and was scored as mild for the large majority of these patients, generally consistent with previous trials. There were no drug-related serious or systemic adverse events for any of the treatment groups.
"With this positive Mercury 2 data, we now have two successful pivotal trials for Roclatan™. The topline efficacy results demonstrated in Mercury 2 are consistent with Mercury 1, confirming the potential for Roclatan™ to become the most efficacious IOP-lowering therapy to enter the market, if approved. Now that the efficacy results for both Mercury 1 and 2 have proven successful, and if the Mercury 1 12-month safety results are also successful, we expect to submit our Roclatan™ NDA (new drug application) in the first half of 2018," said Vicente Anido, Jr., Ph.D., Chairman and Chief Executive Officer at Aerie.

Dr. Anido continued, "In addition to the excellent efficacy observed in Mercury 2 for both Roclatan™ and Rhopressa™, we were also delighted to see relatively low discontinuation rates for the 90-day Mercury 2 trial of 9.8 percent and 10.6 percent for Roclatan™ and Rhopressa™, respectively."

Richard A. Lewis, M.D., Aerie's Chief Medical Officer, added, "Roclatan™ is distinguished by its ability to lower intraocular pressure to levels previously unseen with current glaucoma therapies, including market-leading latanoprost. This product holds the promise of potentially becoming the first prostaglandin fixed-dose combination available in the United States. The safety profile of Roclatan™ observed in Mercury 2 once again points to a safe and tolerable product."

About Roclatan

Roclatan™ is a once-daily eye drop that combines Rhopressa™, as described below, with latanoprost, a widely prescribed PGA. Based on the Company's preclinical studies and clinical trials to date, Aerie believes that Roclatan™, if approved, would be the first glaucoma product to lower IOP through all known mechanisms: (i) increasing fluid outflow through the trabecular meshwork, the eye's primary drain, (ii) increasing fluid outflow through the uveoscleral pathway, the eye's secondary drain, (iii) reducing fluid production in the eye, and (iv) reducing episcleral venous pressure (EVP). By covering the full spectrum of known IOP-lowering mechanisms, Roclatan™ has the potential to provide a greater IOP-lowering effect than any currently approved glaucoma product.

The first Phase 3 registration trial for Roclatan™, named Mercury 1, is a 12-month safety trial, which had a successful 90-day efficacy readout in September 2016. The 12-month safety data from this trial are expected in the third quarter of 2017. The second Phase 3 registration trial, named Mercury 2, is a 90-day efficacy trial, which just completed and is the subject of this press release. The topline 90-day efficacy readouts for both Mercury 1 and Mercury 2 demonstrated that Roclatan™ was statistically superior to each of its components, thus achieving their primary clinical endpoints. Aerie expects to submit a Roclatan™ NDA to the U.S. Food and Drug Administration (FDA) in the first half of 2018. A third Phase 3 registration trial, named Mercury 3, is expected to commence in Europe in mid-2017. Mercury 3 is not necessary for approval in the U.S., but rather to facilitate regulatory approval and commercialization in Europe.

About Rhopressa

Rhopressa™ (netarsudil ophthalmic solution) 0.02%, is a novel eye drop that the Company believes, if approved, would become the only once-daily product available that, based on Aerie's preclinical and clinical studies to date, specifically targets the trabecular meshwork, the eye's primary fluid drain and the diseased tissue responsible for elevated IOP in glaucoma. Preclinical and clinical studies have also demonstrated that Rhopressa™ lowers episcleral venous pressure, which contributes approximately half of IOP in healthy subjects. Further, based on Aerie's preclinical studies, Rhopressa™ may provide an additional mechanism that reduces fluid production in the eye and therefore lowers IOP. Biochemically, the active ingredient in Rhopressa™, netarsudil, has been shown in Aerie studies to inhibit both Rho kinase (ROCK) and norepinephrine transporter (NET). Recent preclinical studies have also shown that Rhopressa™ may have disease-modifying properties, including an anti-fibrotic effect of netarsudil on trabecular meshwork cells and the potential to increase perfusion of the trabecular meshwork.

The results of two Phase 3 registration trials (Rocket 2 and Rocket 1) for Rhopressa™ were included in the NDA submission to the FDA in February 2017. There were two additional Phase 3 registration trials for Rhopressa™, named Rocket 3 and Rocket 4. Rocket 3 was a small 12-month safety-only study in Canada that was not necessary for the NDA submission and for which enrollment has been discontinued. Rocket 4, which was successfully completed in April 2017, was designed to provide adequate six-month safety data for regulatory filing purposes in Europe, and was also not necessary for the NDA submission. The 90-day efficacy results from Rocket 4 and Mercury 1, the initial Phase 3 registration trial for Aerie product candidate Roclatan™ (netarsudil/latanoprost ophthalmic solution) 0.02%/0.005%, were also included in the Rhopressa™ NDA submission as supportive. The FDA has set the Prescription Drug User Fee Act (PDUFA) goal date for the completion of the FDA's review of the Rhopressa™ NDA for February 28, 2018.
