Clearside Biomedical, Inc. Announces Third Quarter 2017 Financial Results and Provides Corporate Update

Nov 8, 2017

ALPHARETTA, Ga., Nov. 08, 2017 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a late-stage clinical biopharmaceutical company developing first-in-class drug therapies to treat back-of-the-eye diseases, today reported financial results for the quarter and nine months ended September 30, 2017 and provided an update on its key development programs.

“More than 300 patients suffering from sight-threatening diseases have received suprachoroidal injections of CLS-TA in Clearside’s clinical development programs designed to support our pursuit of transformative, elegant, precise solutions to restore and preserve vision,” said Daniel H. White, Chief Executive Officer and President. “By leveraging exclusive access to the suprachoroidal space and proprietary technology for suprachoroidal injection of CLS-TA to access the retina and choroid, we believe that we can provide greater bioavailability to the diseased tissue and that drug may last more than 90 days in the eye.  We believe clinicians may more effectively treat sight-threatening diseases like uveitis, retinal vein occlusion and diabetic macular edema, with less incidence of side effects than with traditional routes of administration.   We have a number of key milestones, including preliminary data readouts, coming up over the next few months, and look forward to updating our stakeholders as we continue to advance our pipeline.”

Update on Key Development Programs

CLS-TA, Clearside’s proprietary suspension formulation of the corticosteroid triamcinolone acetonide for suprachoroidal administration (“suprachoroidal CLS-TA”), 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, its 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 preliminary results from this trial in the first quarter of 2018.

Macular Edema Associated with Retinal Vein Occlusion (“RVO”)

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 in combination with intravitreally administered EYLEA® (aflibercept) (“intravitreal Eylea”) in patients with RVO. The primary objective of this trial is to determine the proportion of patients in the combination treatment arm, compared to the intravitreal Eylea alone 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 endpoints will also be evaluated. Patient enrollment is proceeding as planned, and Clearside currently expects to report preliminary data from this trial in the first quarter of 2019.

Clearside is also making preparations to initiate TOPAZ, a second multicenter, randomized, masked, controlled Phase 3 clinical trial of suprachoroidal CLS-TA in combination with an anti-VEGF agent for the treatment of patients with RVO. While Clearside plans to announce detailed information about TOPAZ at a later date, this trial is expected to have a similar design to the SAPPHIRE trial. Clearside anticipates enrollment of the first patient in the TOPAZ Phase 3 trial in the first quarter of 2018.

Diabetic Macular Edema (“DME”)

In April 2017, Clearside completed enrolling 20 patients with DME in HULK, an open-label, multi-center Phase 1/2 clinical trial. The goal of the HULK trial was to obtain safety data and to observe efficacy outcomes from administering a combination of intravitreal Eylea and suprachoroidal CLS-TA, as well as suprachoroidal CLS-TA alone, over a six-month evaluation period in the DME patient population. Initial results suggest encouraging efficacy with a trend toward durability, particularly in the combination treatment arm. Suprachoroidal CLS-TA, both alone and in combination with intravitreal Eylea, has been well tolerated to date.

Clearside expects to report preliminary results from the HULK trial on November 10th at the Retina Subspecialty Day of the American Academy of Ophthalmology 2017 Annual Meeting in New Orleans.

In October 2017, Clearside announced completion of patient enrollment in TYBEE, a multicenter, randomized, masked, controlled Phase 2 clinical trial designed to evaluate the safety and efficacy of suprachoroidal CLS-TA used in combination with intravitreal Eylea in patients with DME who are naïve to treatment.  In this trial, 71 patients were 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 of mean change from baseline in best corrected visual acuity between the two study arms. An additional analysis will include a comparison between the number of injections required between the two groups. Patient follow-up in the TYBEE trial is 6 months after initial treatment and Clearside expects to announce preliminary data in the second quarter of 2018.

Pipeline and Collaborations

Clearside continues nonclinical efforts both internally and with multiple collaborations in development areas such as gene therapy for inherited retinal disorders, wet age-related macular degeneration (“wet AMD”), and other ocular diseases that may benefit from a suprachoroidal administration of treatment approach.

Third Quarter 2017 Financial Results

Clearside’s research and development expenses for the three months ended September 30, 2017 were $16.1 million, compared to $3.7 million for the third quarter of 2016, an increase of $12.4 million. This was primarily attributable to an increase in costs related to Clearside’s clinical programs.  Costs for Clearside’s uveitis program increased $1.8 million, costs for its RVO program increased $8.4 million, which included purchases of Eylea for SAPPHIRE and start-up costs for TOPAZ, and costs for its DME program increased $1.9 million. In addition, Clearside incurred a $0.6 million increase in employee-related costs due to an increase in headcount to support the increased clinical trial activities.

General and administrative expenses were $2.3 million for the third quarter of 2017, compared to $1.6 million for the same period last year, an increase of $0.7 million. This year-over-year increase was primarily attributable to an increase of $0.6 million in employee-related costs and an increase of $0.1 million in patent-related expenses. 

Cash, cash equivalents and short-term investments totaled $52.6 million as of September 30, 2017, compared to $83.6 million as of December 31, 2016.  Clearside believes that its current financial resources are sufficient to fund operations into the fourth quarter of 2018.

Net loss for the third quarter of 2017 was $18.3 million, or $0.72 per share of common stock, compared to $5.6 million, or $0.28 per share of common stock, for the third quarter of 2016.  The increase in net loss and net loss per share is primarily attributable to higher research and development expenses in the third quarter of 2017 compared to the third quarter of 2016.
