Phase 3 Program of Zuprata™ for Macular Edema Associated with Retinal Vein Occlusion to be Initiated in the First Half of 2017
Phase 1/2 Trial for Diabetic Macular Edema to be Initiated by the End of 2016
ALPHARETTA, Ga., Nov. 09, 2016 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a late-stage biopharmaceutical company developing first-in-class drug therapies to treat back-of-the-eye diseases, today reported financial results for the quarter ended September 30, 2016 and provided an update on its development programs.
“At Clearside, we are relentlessly pursuing transformative, elegant, precise solutions to restore and preserve vision,” said Daniel H. White, Chief Executive Officer and President. “That pursuit has resulted in the achievement of a number of important milestones again in the third quarter of 2016. Noteworthy among those was the report of encouraging additional top-line data from our Phase 2 clinical trial of Zuprata™, our proprietary form of the corticosteroid triamcinolone acetonide, in patients with macular edema associated with retinal vein occlusion. We believe that an injection of Zuprata administered to the suprachoroidal space along with an intravitreal injection of an anti-VEGF agent like aflibercept, has the potential to improve visual outcomes relatively rapidly as compared to treatment with anti-VEGF monotherapy.”
Update on Key Development Programs
Macular Edema Associated with Non-Infectious Uveitis
At the American Society of Retina Specialists annual meeting in August 2016, Clearside presented findings from a Phase 2 clinical trial of suprachoroidally administered Zuprata (“suprachoroidal Zuprata”) for the treatment of macular edema associated with non-infectious uveitis. As previously reported, this trial met its primary endpoint, with a statistically significant mean reduction from baseline in retinal thickness of 164 microns at eight weeks following dosing (p=0.002). There was also a statistically significant mean 9 letter improvement in best corrected visual acuity at eight weeks following dosing (p=0.0004).
Clearside is continuing to enroll patients in PEACHTREE, its Phase 3 trial of suprachoroidal Zuprata in macular edema associated with non-infectious uveitis. This 6-month pivotal trial is expected to enroll approximately 150 patients, with approximately 90 patients being randomized into an active treatment arm to receive suprachoroidal Zuprata and approximately 60 patients being randomized into a control arm to receive a sham suprachoroidal procedure with no drug administered.
Macular Edema Associated with Retinal Vein Occlusion
During the 2016 Retina Sub-Specialty Day at the American Academy of Ophthalmology annual meeting in October, Dr. David M. Brown presented results from Clearside’s Phase 2 TANZANITE trial of suprachoroidal Zuprata in patients with macular edema associated with retinal vein occlusion (“RVO”). In this controlled, masked, randomized trial, researchers compared the administration of an intravitreal injection of an anti-VEGF agent, aflibercept, in combination with suprachoroidal Zuprata to the administration of intravitreal aflibercept alone. Patients received additional intravitreal aflibercept treatments as needed. In this trial, Clearside observed both visual acuity improvements and macular edema reductions over a 3-month period following initial dosing, with 60% fewer additional intravitreal aflibercept injections in the aflibercept in combination with Zuprata arm than in the control monotherapy aflibercept arm.
Based on feedback from a recent End-of-Phase 2 meeting with the U.S. Food and Drug Administration (“FDA”), Clearside intends to initiate Phase 3 trials of suprachoroidal Zuprata in treating RVO. While Clearside plans to announce detailed information about these Phase 3 trials at a later date, these trials are being designed to assess whether suprachoroidal Zuprata in combination with intravitreal aflibercept show superior visual acuity outcomes as compared to monthly injections of intravitreal aflibercept alone. Clearside anticipates dosing of the first patient in an RVO Phase 3 trial in the first half of 2017.
Diabetic Macular Edema (“DME”)
In the Phase 2 TANZANITE trial, suprachoroidal Zuprata met the primary endpoint and Clearside observed encouraging visual acuity and macular edema improvements in patients with RVO. Accordingly, Clearside intends to expand its Zuprata clinical development programs to include another retinal vascular condition, DME. To that end, Clearside is planning a multi-center, open-label Phase 1/2 trial to evaluate a combination therapy of aflibercept and Zuprata, as well as Zuprata monotherapy, in patients with DME over a 6-month evaluation period. Clearside expects to enroll the first patient in this trial before the end of 2016.
Wet Age-Related Macular Degeneration (“wet AMD”)
Earlier this year, Clearside selected axitinib as the lead compound for its development program for the treatment of wet AMD through suprachoroidal administration due to its potency in targeting the VEGF and PDGF receptors, and because of its long half-life when injected suprachoroidally. Clearside is developing a proprietary suspension formulation of axitinib and has scheduled a pre-Investigational New Drug (“IND”) meeting with the FDA prior to the end of 2016. Following this meeting, Clearside expects to submit an IND application for axitinib for the treatment of wet AMD.
Third Quarter 2016 Financial Results
Clearside’s research and development expenses were $3.7 million for the quarter ended September 30, 2016, compared to $2.3 million for the same period in 2015. The increase was primarily due to ongoing costs of the PEACHTREE Phase 3 clinical trial and increased manufacturing costs associated with the potential commercialization of suprachoroidal Zuprata. Clearside expects research and development expenses to continue to increase as additional clinical trials are conducted.
General and administrative expenses were $1.6 million for the quarter ended September 30, 2016, compared to $1.1 million in the third quarter of 2015. The increase was primarily due to higher employee-related expenses and costs related to being a public company, including increased directors and officers insurance, professional fees and non-employee director compensation.
Cash, cash equivalents and short-term investments totaled $56.9 million as of September 30, 2016, compared to $20.3 million as of December 31, 2015. The increase reflects total net proceeds of $51.4 million received from Clearside’s initial public offering in June 2016, including the exercise of the underwriters’ option to purchase additional shares, partially offset by increased total operating expenses.
Net loss for the quarter ended September 30, 2016 was $5.6 million, or $0.28 per share, compared to $3.5 million, or $1.31 per share, for the same period in 2015.
