Opko Health, Inc. Acquires Rights to Innovative Ocular Product to Prevent Serious Eye Infections

MIAMI, Oct. 30 /PRNewswire-FirstCall/ -- OPKO Health, Inc. today announced that it has acquired exclusive worldwide rights to a novel ocular product for use following invasive retinal procedures to prevent the development of endophthalmitis, a devastating complication that can lead to blindness and loss of the affected eye. The device was invented by two retinal surgeons who serve as clinical advisors to OPKO.

"Experts are raising the alarm about a significant rise in cases of endophthalmitis, a devastating complication of invasive ocular procedures that can result in complete blindness and surgical removal of the infected eye," said Samuel Reich, Executive Vice President of Ophthalmologics at OPKO. "We believe this easy-to-use, elegant ocular product can reduce the incidence of endophthalmitis in the significant number of patients at risk annually."

Experts believe that the incidence of endophthalmitis is growing as a result of the rising number of ocular surgeries being performed, the widespread adoption of sutureless surgical techniques and a significant increase in the number of intravitreal injections. With the advent of injectable therapies such as Lucentis(R) for the treatment of wet age-related macular degeneration (wet AMD), the annual number of injections has risen rapidly. There are estimated to be over 1.5 million invasive retinal procedures, including both surgeries and intravitreal injections, being currently performed in the U.S. alone, and the number is believed to be rising significantly. While most patients suffer no adverse effects from intravitreal injections, all patients who receive invasive retinal procedures are at risk of developing endophthalmitis. There are no products currently available that are specifically designed and optimized for the prevention of endophthalmitis following retinal surgeries and intravitreal injections.

"Endophthalmitis is a complication dreaded by eye care professionals, since its outcome is so devastating for patients," said Dr. Richard S. Kaiser, M.D., a retinal specialist at the Wills Eye Institute, a co-inventor of this product and an author of a forthcoming paper on the increased incidence of endophthalmitis in the journal Ophthalmology." Dr. Kaiser's paper showed a greater than 12-fold increase in the likelihood of endophthalmitis when utilizing new sutureless retinal surgery techniques compared to older approaches.

Dr. Kaiser added, "As practicing retinal surgeons, we designed this collagen-based device specifically for routine use after retinal surgeries and intravitreal injections. We are optimistic that this new product will be effective in helping to reduce the risk of this catastrophic complication among retinal patients."

Terms of the agreement were not disclosed.

About Endophthalmitis

Endophthalmitis involves inflammation of the intraocular cavities of the eye, usually caused by infection. It typically results as a complication of ocular surgery, intraocular injections or trauma. The injections can expose the eye to potential pathogens and leave behind a needle tract that can also serve as an entrance for a bacterial infection. In addition, retinal surgery is increasingly performed using a new sutureless technique, leaving open wounds to heal over time and potentially exposing the inner structures of the eye to possible infection. Symptoms of endophthalmitis can include pain, redness, lid swelling and decreased visual acuity. Treatment includes antibiotic injections to the infected eye. Despite aggressive therapy, endophthalmitis can be devastating; frequently requiring enucleation, or removal of the infected eye.
