Clearside Biomedical Announces First Patients Enrolled in Phase 1/2a Clinical Trial of CLS-AX (axitinib injectable suspension) for the Treatment of Wet AMD

ALPHARETTA, Ga., Jan. 12, 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, announced today that the first patients have been enrolled in its Phase 1/2a clinical trial of CLS-AX (axitinib injectable suspension) in patients with neovascular age-related macular degeneration (wet AMD). Clinical sites, all based in the United States, are activated and currently screening wet AMD patients for this Phase 1/2a trial, known as OASIS, involving CLS-AX, a proprietary suspension of axitinib for suprachoroidal injection.

“The enrollment of the first patients for our OASIS trial is a key milestone for Clearside as we execute our strategy to expand our ophthalmology pipeline with innovative and relevant opportunities targeting critical medical needs through the suprachoroidal space (SCS®),” said George Lasezkay, Pharm.D., J.D., President and Chief Executive Officer. “We believe that axitinib, a small molecule tyrosine kinase inhibitor (TKI), could provide safety and efficacy comparable to, or better than, current standard of care. And by delivering axitinib as a suspension into the suprachoroidal space using our in-office, non-surgical SCS Microinjector®, we may potentially extend the duration of therapeutic action and reduce or relieve the profound treatment burden for wet AMD patients. We expect data from our first cohort of patients in mid-2021.”

OASIS is a Phase 1/2a open-label, dose-escalation study in wet AMD patients to assess the safety and tolerability of a single dose of CLS-AX administered by suprachoroidal injection. Eligible patients are those who demonstrate stable visual acuity following two or more previous injections with an intravitreal anti-VEGF agent. Enrolled patients initially receive aflibercept at the first visit followed by a single dose of CLS-AX at the second visit one month later. The primary endpoint for the trial will assess the safety and tolerability of CLS-AX for the three months following the administration of CLS-AX, and secondary endpoints will evaluate the pharmacokinetics, visual function, ocular anatomy, and the need for additional treatment with intravitreal aflibercept during the three month period.

The study design consists of 3 cohorts of 5 patients each (n=15). Cohort 1 participants will receive the lowest dose, 0.03 mg of axitinib delivered via suprachoroidal injection. Dose escalation will then proceed following review of the safety data by the Safety Monitoring Committee and their recommendation to advance to the next higher dose cohort. Additional information on the Phase 1/2a trial can be found on https://clinicaltrials.gov (NCT04626128).

In preclinical studies, CLS-AX delivered suprachoroidally was observed to be well tolerated and showed significant ocular tissue concentrations over time. These characteristics, if demonstrated clinically, may support the potential for suprachoroidal axitinib to reduce or relieve the treatment burden for patients suffering from wet AMD.

About CLS-AX (axitinib injectable suspension)

CLS-AX (axitinib injectable suspension) is a proprietary suspension of axitinib for suprachoroidal injection. Axitinib is a tyrosine kinase inhibitor (TKI) currently approved to treat renal cell cancer that achieves pan-VEGF blockade, directly inhibiting VEGF receptors-1, -2, and -3 with high potency and specificity. Clearside believes this broad VEGF blockade may have efficacy advantages over existing retinal therapies by acting at a different level of the angiogenesis cascade, and may benefit patients who sub-optimally respond to current, more narrowly focused anti-VEGF therapies. Suprachoroidal injection of this proprietary suspension of axitinib has demonstrated meaningful potential in preclinical studies in multiple species. Preclinical results from Clearside and independent investigators have shown pharmacodynamic effects with reduced growth of experimental neovascularization and decreased fluorescein leakage. With suprachoroidal administration of axitinib, there is the potential to achieve prolonged duration and targeted delivery to affected tissue layers. Clearside is developing CLS-AX as a long-acting therapy for the treatment of wet AMD. CLS-AX is currently in a Phase 1/2a clinical trial and additional information can be found on https://clinicaltrials.gov (NCT04626128).
