About Glaucoma and NB1111
Glaucoma is considered one of the optic neuropathies, indicating that there is damage to the cells that comprise the optic nerve. The damage is irreversible, leading to progressive vision loss and ultimately blindness if left untreated. There are over one million fibers that comprise the optic nerve and these can become damaged when pressure in the eye rises to a level that results in a direct crush injury or deprives these fibers of oxygen or nutrients from neighboring blood vessels.
Currently approved therapies are focused on lowering intraocular pressure (IOP) in order to sustain the nerve fibers and prevent a process of programmed cell death or apoptosis. These therapies are applied by eyedrop, with dosages ranging from once daily to up to three times per day, depending on the class of medicine used. The goal of the particular therapies is either to enhance drainage out of the eye, or lower fluid production inside the eye.
Globally, more than half of those treated for glaucoma require two or more drug classes to manage their disease as this is often referred to as a non-responder market. The elusive goal in managing glaucoma is the ability to provide direct neuroprotection to these optic nerve cells in order to preserve vision beyond just lowering IOP.
Cannabinoid molecules, particularly THC, have been shown to stimulate two types of cannabinoid receptors in the body. These receptors were previously believed to be located only in the brain and bone marrow, however it is now recognized that these receptors are located throughout the body, with one of the highest densities located in the eye. These ocular receptors are particularly located on organs in the eye that regulate IOP. Stimulation of the receptors by THC results in opening of channels in organs associated with fluid drainage such as the trabecular meshwork, the uveoscleral vein, and the iris and ciliary body.
NB1111 is a prodrug of THC which has no physiological activity itself, but is designed to help transport the active part of the molecule, THC, into the eye. Once inside the eye, NB1111 is cleaved by enzymes in the eye, and THC is then released to bind to cannabinoid receptors. THC has been shown in both human and animal experiments since the 1970’s to lower IOP however the cannabinoid chemistry was not conducive to direct ocular delivery. NB1111 is unique because this is the first time a direct topical application of THC, bioengineered for optimal absorption into the eye, has been shown in animal experiments to have a sustained lowering of IOP, supporting development as a drug.
Cannabinoids are also known to possess neuroprotective qualities and this is why many types are being studied for conditions associated with neurodegeneration, like epilepsy, Parkinson’s disease, and multiple sclerosis. Data from multiple species have shown the utility of cannabinoids like THC in preventing programmed cell death of the cells comprising the optic nerve. Experiments performed at the University of Mississippi have shown that topical administration of NB1111 into the eyes of rabbits have resulted in THC reaching the retina and binding to receptors there, strengthening the evidence for use as a neuroprotectant as well as lowering IOP. This duality in activity would make NB1111 valuable not only in hypertensive glaucoma, but could also meet the needs of Asian patients with normotensive glaucoma; direct neuroprotection of the optic nerve without the presence of elevated IOP.
About the Glaucoma Market
Glaucoma is the second leading cause of blindness globally. It accounts for roughly 35 million prescriptions in the $3 billion US market (source: Market Watch, 2018), and projections estimate the worldwide market could exceed $8 billion by 2023 as the prevalence of this eye disease increases, especially in Asia. Current therapies focus on lowering intraocular pressure to help preserve retinal ganglion cells that comprise the optic nerve. The two major goals in developing a cannabinoid-based therapy for glaucoma are to not only lower intraocular pressure but exert a direct neuroprotective effect on the cells comprising the optic nerve to preserve vision for affected patients, a capability that current drugs are unable to provide. It is estimated that roughly 10% - 15% of patients in North America and the European Union that have glaucoma remain undiagnosed and untreated.
