Neurotrophic keratitis (NK), also known as neurotrophic keratopathy, is a rare and progressive eye disease affecting the cornea, which can lead to corneal scarring and vision loss. NK is primarily caused by damage to the trigeminal nerve – the largest of the cranial nerves – which conveys sensory information. This damage can lead to loss of corneal sensitivity, ultimately impairing corneal health.
Before Oxervate, existing treatment options for NK were limited to invasive surgical procedures and symptomatic treatments. These treatments, including artificial tears and antibiotics, failed to target the underlying pathology of the disease.
Oxervate eye drops contain cenegermin-bkbj, a recombinant form of human nerve growth factor that is structurally identical to the nerve growth factor (NGF) protein made in ocular tissues. NGF acts directly on corneal epithelial cells, which make up the outermost layer of the cornea, to stimulate cell growth and survival. Additionally, NGF is known to bind receptors on lacrimal glands to promote tear production, helping to lubricate and protect the eye.
The safety and efficacy of Oxervate was tested in 151 patients with NK in two clinical trials. Seventy percent of patients treated with the eye drops demonstrated complete corneal healing in eight weeks.
Alright, let's simplify this:
Imagine your eyes have their own superheroes that keep them strong and healthy. But sometimes, something happens to these superheroes, and they can't do their job well anymore. That's what happens with a rare eye problem called neurotrophic keratitis (NK).
Before, doctors didn't have many good ways to help fix this problem. They could only do big surgeries or give medicines that didn't really fix the main issue. But then, in 2018, something amazing happened! A special eye drop called Oxervate was made. It's like magic water that helps the superheroes in your eyes become strong again.
Oxervate has a special ingredient called cenegermin-bkbj, which is like food for the superheroes in your eyes. When you put these drops in your eyes, it helps the superheroes grow back and become strong again. And guess what? In tests, lots of people who used Oxervate got better really fast!
So now, if someone's eyes have this problem, doctors can give them Oxervate to help make their eyes healthy again. It's like giving them a special potion that makes their eyes feel better and see better too!
