ALPHARETTA, Ga., Aug. 10, 2021 (GLOBE NEWSWIRE) -- Clearside Biomedical, Inc. (NASDAQ:CLSD), a biopharmaceutical company dedicated to developing and delivering treatments that restore and preserve vision for people with serious back of the eye diseases, today reported financial results for second quarter ended June 30, 2021.

“We continue to demonstrate our position as the leader in the suprachoroidal space with numerous clinical trials in multiple indications, a New Drug Application (NDA) for XIPERE™ under regulatory review and recent positive results from our CLS-AX clinical trial,” said George Lasezkay, Pharm.D., J.D., Clearside’s President and Chief Executive Officer. “We are the first company to develop a clinically tested, non-surgical, repeatable micro-injection technology designed to unlock the potential clinical benefits of administering drugs into the suprachoroidal space. We are encouraged by the Cohort 1 results of our OASIS Phase 1/2a trial in wet AMD patients, which achieved its safety and tolerability endpoints. We believe the Cohort 1 data supports our hypothesis that the combination of targeted and compartmentalized suprachoroidal delivery and the potent pan-VEGF attributes of axitinib may facilitate an effective treatment option for patients suffering from wet AMD. We have begun enrollment in Cohort 2 with more than triple the dose used in Cohort 1 and look forward to reporting results by the end of 2021.”

“Following our NDA resubmission for XIPERE for the treatment of macular edema associated with uveitis, the U.S. Food and Drug Administration (FDA) assigned a Prescription Drug User Fee Act (PDUFA) action date of October 30, 2021. If approved, XIPERE would represent the first therapy for macular edema associated with uveitis, the first approved therapeutic delivered into the suprachoroidal space and the first commercial product developed by Clearside. In addition to progressing our internal development initiatives, we continue to work closely with our commercial and drug development partners, and expect data from their ongoing clinical trials using our SCS Microinjector® later this year,” concluded Dr. Lasezkay.

Key Highlights

  • Patient enrollment is underway in Cohort 2 of OASIS, Clearside’s U.S. based, open-label, dose-escalation Phase 1/2a trial in wet AMD patients, to assess the safety and tolerability of a 0.1 mg dose of CLS-AX administered by suprachoroidal injection via Clearside’s SCS Microinjector®.
  • Clearside reported positive results from Cohort 1 of OASIS in six patients (n=6) with neovascular age-related macular degeneration (wet AMD). The primary endpoints were achieved in Cohort 1, as the initial lowest planned dose of 0.03 mg CLS-AX was well tolerated with no serious adverse events and no drug related treatment emergent adverse events observed throughout the study period.
  • FDA accepted the XIPERE NDA resubmission and assigned a PDUFA action date of October 30, 2021.
  • Multiple presentations featuring the use of Clearside’s proprietary suprachoroidal space (SCS®) delivery platform to administer small molecules and gene therapy were highlighted at global conferences, including the Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting and the Wet AMD & DME Drug Development Summit.
  • Data was published in Translational Vision Science & Technology titled “Evaluation of Long-Lasting Potential of Suprachoroidal Axitinib Suspension Via Ocular and Systemic Disposition in Rabbits” in June 2021.

Second Quarter 2021 Financial Results

Clearside’s license and other revenue for the second quarter of 2021 was $0.8 million, compared to $0.4 million for the second quarter of 2020. This increase was primarily attributable to higher revenue from partner licensing agreements in the second quarter of 2021.

Research and development expenses for the second quarter of 2021 were $4.1 million, compared to $3.3 million for the second quarter of 2020. This increase was primarily attributable to increased costs for continued development of pipeline programs and employee-related expenses.

General and administrative expenses for the second quarter of 2021 were $2.8 million, compared to $2.6 million for the second quarter of 2020. This increase was primarily attributable to an increase in employee-related expenses.

Net loss for the second quarter of 2021 was $6.1 million, or $0.11 per share of common stock, compared to a net loss of $5.8 million, or $0.13 per share of common stock, for the second quarter of 2020. This increase in net loss was primarily attributable to higher research and development expenses in the second quarter of 2021. The change in net loss per share was related to the increase in shares outstanding.

As of June 30, 2021, Clearside’s cash and cash equivalents totaled $26.4 million. The Company believes it will have sufficient resources to fund its planned operations into the second quarter of 2022, not including receipt of potential partner milestone payments.
