Compact Imaging, Inc. (CI), a developer of miniaturized optical coherence tomography (OCT) devices, today announced the signing of a collaboration agreement with Novartis Pharma AG under which Novartis will fund Compact Imaging’s development of a low-cost home-based monitor to detect disease progression in advanced cases of age-related macular degeneration (AMD) and diabetic retinopathy (DR). These two diseases are the leading causes of blindness in developed countries and affect approximately 350 million people worldwide.
Although drug therapeutics (specifically, anti-vascular endothelial growth factor, or anti-VEGF, agents) can effectively treat active (or "wet") AMD and diabetic macular edema (DME), the therapeutic regimen can be arduous. For example, in addition to receiving periodic intraocular injections, patients must visit their physicians frequently to have disease progression monitored using a large-scale in-clinic OCT instrument. Although patients, their caregivers and physicians expend considerable time and resources for these visits, treatment often is not indicated. Such "no treatment" visits can become overly burdensome for patients, increasing the already high chances that they will drop out of treatment and risk significant loss of visual acuity. Moreover, as the number of patients with these indications has soared due to an aging population and the diabetes epidemic, the existing care model that has been built around frequent clinic visits has created an unsustainable burden across many healthcare systems.
Home retinal monitoring based on Compact Imaging’s proprietary MRO™ (Multiple Reference OCT) technology is expected to provide a simple and affordable solution to these problems. The personal devices will enable quick and easy monitoring in patients’ homes. The collected OCT information then will be transmitted via cloud to treating physicians. If the data show the possibility of clinically-significant disease progression, the patient will be promptly notified by his or her treating physician to visit the clinic for a complete diagnostic exam and, if indicated, anti-VEGF treatment.
"We appreciate Novartis Pharma AG’s commitment to advancing development of a practical device that will enable patients to monitor progression of vision-threatening retinal diseases at home," said Don Bogue, Compact Imaging CEO. "Home monitoring and rapid reporting of results to treating physicians has the potential to dramatically transform this burdensome patient care model. Most importantly, it will help patients around the world get the full benefit of today’s sight-saving therapies."
Compact Imaging has already demonstrated the technical feasibility of MRO for use in this application, achieving results comparable to clinical OCT in a study measuring retinal thickness in healthy eyes. The Company expects to begin clinical trials of a prototype system with patients having an active AMD or DME diagnosis in the second half of 2019.
"The patient-focused goals of this Compact Imaging/Novartis collaboration complement Novartis’ efforts to introduce new anti-VEGF therapeutics for active AMD and DME that will reduce the frequency of injections, extend the time between follow-up visits and provide physicians new tools to help manage these serious chronic conditions," said Dr. Michael R. Hee, MD, PhD, Chief Medical Officer at Compact Imaging. "Clinically useful data on retinal disease progression from home monitoring devices also could prove extremely valuable in optimizing drug dosing and future drug development."
