ATLANTA--()--Clearside Biomedical, Inc., a privately held company specializing in the research and development of ophthalmic pharmaceuticals, today announced the successful dosing of patients in a safety and tolerability clinical study using its proprietary ocular microinjection platform to deliver therapeutics to treat retinal disease.
“It was done only with topical anesthesia, making this a viable procedure to deliver medications to the retina and choroid.”
“I am extremely proud of the Clearside Biomedical research and development group for reaching our milestone of conducting a clinical trial within less than a year of receiving funding,” said Daniel White, President and CEO of Clearside Biomedical. “The treatment of these patients is an important step in the development of the microinjection platform as a preferred technique for delivering drugs to the retina and choroid through the suprachoroidal space within the current standards of medical practice in vitreo-retinal medicine.”
The open-label safety and tolerability study involved the administration of bevacizumab into the suprachoroidal space (SCS) of the eye using Clearside Biomedical’s proprietary microinjection platform. The clinical trial was conducted by Principal Investigator Dr. Virgilio Morales-Cantón, who is the head of the Retina and Vitreous Department at the Asociación para Evitar la Ceguera (APEC) in Mexico City. Administration to the SCS was achieved in all patients and was confirmed via ophthalmoscope. The four patients in the trial suffer from advanced, wet age-related macular degeneration (AMD). AMD is a deterioration of the eye's macula, a small area in the retina that is responsible for central vision. AMD can eventually lead to blindness if left untreated.
“In my opinion, this study is pivotal for the company since it demonstrated that the suprachoroidal microinjection procedure was well-tolerated by the patient,” said Dr. Peter K. Kaiser, Professor of Ophthalmology and retina specialist at the Cole Eye Institute at the Cleveland Clinic. “It was done only with topical anesthesia, making this a viable procedure to deliver medications to the retina and choroid.”
Clearside Biomedical’s in-office injection procedure delivers drugs to the choroid and retina through the suprachoroidal space, a tissue compartment within the eye, allowing medication to be applied directly to the area affected by disease. As demonstrated in previous nonclinical studies and the initial clinical study, dosing into the SCS appears to be safe and well-tolerated in the first month of safety assessments.
Company Plans to File an IND on CLS 1001:
Clearside Biomedical held a pre-IND meeting with the U.S. Food and Drug Administration to discuss the development plan of its initial product, CLS 1001. Based on this meeting, the company plans to file an Investigational New Drug (IND) application by the end of the year to enable initiation of the clinical program in the United States.
The original technology was developed collaboratively by the Emory University School of Medicine and Georgia Institute of Technology, and Clearside Biomedical received an initial $4 million in funding in January 2012 from Hatteras Venture Partners, Georgia Research Alliance Venture Fund and Kenan Flagler Venture Fund. Based on the straightforward regulatory path for the initial product, CLS 1001, Clearside Biomedical anticipates raising additional capital through a series B round to initiate and complete pivotal testing of the product candidate and to file a new drug application.
