ALPHARETTA, Ga., Aug. 09, 2017 (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 and six months ended June 30, 2017 and provided an update on its development programs.
“Clearside’s pursuit of transformative, elegant, precise solutions to restore and preserve vision resulted in the achievement of a number of recent key milestones,” said Daniel H. White, Chief Executive Officer and President. “Noteworthy among those was completion of patient enrollment in our pivotal Phase 3 trial for the treatment of macular edema associated with non-infectious uveitis, Clearside’s most advanced clinical development program, and the enrollment of the first patient in our Phase 3 trial for the treatment of patients with macular edema associated with retinal vein occlusion.”
Update on Key Development Programs
CLS-TA for suprachoroidal administration (“suprachoroidal CLS-TA”), Clearside’s proprietary suspension formulation of the corticosteroid triamcinolone acetonide, is part of Clearside’s pipeline of potential treatments for unmet or underserved blinding eye diseases where the pathologies manifest in the choroid and retina. Suprachoroidal CLS-TA is being studied for potential administration both alone and together with an intravitreal anti-VEGF agent.
Macular Edema Associated with Non-Infectious Uveitis
In early August 2017, Clearside completed patient enrollment in PEACHTREE, the pivotal Phase 3 trial of suprachoroidal CLS-TA in patients with macular edema associated with non-infectious uveitis. Patient follow-up in PEACHTREE will continue for 6 months after initial treatment. Accordingly, Clearside expects to report top-line results from the trial in the first quarter of 2018.
Macular Edema Associated with Retinal Vein Occlusion (“RVO”)
On June 8, 2017, Clearside announced that, at the 40th Annual Macula Society Meeting, Charles C. Wykoff, M.D., Ph.D. presented preliminary results from a non-interventional trial (the “Extension Study”) of patients who had participated in the completed Phase 2 clinical trial (“TANZANITE”) of suprachoroidal CLS-TA used together with intravitreally administered EYLEA® (aflibercept) (“intravitreal Eylea”) for the treatment of RVO. Based on the small number of patients in the TANZANITE trial’s combination arm that received additional retreatment, the substantial unmet need associated with frequent office visits and injections required in this patient population, and after feedback from investigators, Clearside performed a retrospective analysis of patient charts that included 3 months from the TANZANITE trial and at least a 6-month follow-on period to more thoroughly assess the duration of effect of the combination treatment and the potential to reduce the burden of therapy. In the analysis presented by Dr. Wykoff, 17 of the 23 patients in the combination arm of the TANZANITE trial, or 74%, did not receive any additional treatment over the 9-month time frame, compared to only 4 of 23 patients, or 17%, in the Eylea-only arm during that same period of time who did not need further treatment.
Clearside continues to enroll patients in SAPPHIRE, a multicenter, multi-country, randomized, masked, controlled Phase 3 clinical trial designed to assess the safety and efficacy of suprachoroidal CLS-TA used with intravitreal Eylea in subjects with RVO. The primary objective of this trial is to determine the proportion of patients in a combination treatment arm, compared to a control arm, with best corrected visual acuity improvement of at least 15 letters from baseline at eight weeks after initial treatment. Several secondary efficacy and safety outcomes will also be evaluated.
Diabetic Macular Edema (“DME”)
On April 20, 2017, Clearside announced the completion of patient enrollment in HULK, an exploratory, open-label, multicenter Phase 1/2 clinical trial designed to assess the safety and efficacy of suprachoroidal CLS-TA along with an intravitreal injection of Eylea in patients with DME naïve to treatment. The trial is also assessing the safety and efficacy of suprachoroidal CLS-TA alone in patients with DME who have previously been treated with intravitreal anti-VEGF or intravitreal corticosteroid treatment and still require further treatment. Clearside expects to report preliminary results from the HULK trial by the end of 2017.
On July 11, 2017, Clearside announced the enrollment of the first patient in TYBEE, a multicenter, randomized, masked, controlled Phase 2 clinical trial designed to evaluate the safety and efficacy of suprachoroidal CLS-TA in patients with DME who are naïve to pharmacologic treatment. In this trial, patients will be randomized into either a combination arm to receive suprachoroidal CLS-TA together with intravitreal Eylea or a control arm to receive only intravitreal Eylea. The primary outcome measure is a comparison between the two study arms of change from baseline in best corrected visual acuity at 3 months after initial treatment. Clearside currently expects to report three-month preliminary data from the TYBEE trial in the first half of 2018.
Clearside continues nonclinical efforts with multiple collaborations in gene therapy, complement inhibition, and alternative mechanisms in the treatment of complex retinal diseases.
Second Quarter 2017 Financial Results
Clearside’s research and development expenses for the three months ended June 30, 2017 were $11.5 million, compared to $4.2 million for the second quarter of 2016, an increase of $7.3 million. This increase was primarily attributable to increased costs related to Clearside’s ongoing clinical development programs for CLS-TA and an increase in device manufacturing costs, partially offset by a decrease in costs from completed clinical trials and Clearside’s discontinuation of preclinical studies in its wet AMD program.
General and administrative expenses were $2.3 million for the second quarter of 2017, compared to $1.0 million for the same period last year, an increase of $1.3 million. This year-over-year increase was primarily attributable to an increase of $0.6 million in employee-related costs, a $0.2 million increase for marketing expenses and a $0.5 million increase related to the costs of operating as a public company.
Cash, cash equivalents and short-term investments totaled $66.0 million as of June 30, 2017, compared to $83.6 million as of December 31, 2016.
Net loss for the second quarter of 2017 was $13.8 million, or $0.54 per share of common stock, compared to $5.1 million, or $0.62 per share of common stock, for the second quarter of 2016. The increase in net loss is primarily attributable to higher research and development expenses, while the decrease in net loss per share of common stock is primarily due to an increase in the number of shares of common stock outstanding resulting from Clearside’s financing activities in 2016.
