(London 11-01-2017) Nanomerics today announced that it has licensed the North American rights to NM133 for the treatment of dry eye to IACTA Pharmaceuticals.
IACTA Pharmaceuticals, Inc., a privately held pharmaceutical company, has acquired the North American rights to develop and commercialize NM133, an investigational medicine designed to help treat dry eye.
Professor Andreas Schatzlein, CEO of Nanomerics, said, “Nanomerics believes IACTA is the ideal North American licensee for NM133. The need for better medicines remains undiminished and drugs need to be used to their full potential to deliver patient benefit. Nanomerics’ Molecular Envelope Technology (MET) is engineered at the nanoscale to efficiently deliver drugs for a variety of applications. NM133 is a product in which many of the MET attributes are being exploited to bring tangible benefits to those suffering from dry eye disease.”
Damon Burrows, Founder and CEO of IACTA Pharmaceuticals, said, “We are enthusiastic about partnering with Nanomerics and are grateful that they have placed their trust in us as their North American licensee. We strongly believe in the promise of MET technology for the treatment of a range of conditions including dry eye.”
Molecular Envelope Technology (MET) nanoparticles are engineered from biocompatible polymers. MET particles are engineered by creating amphiphilic polymers which can self-assemble into micelles. Hydrophobic drugs can be encapsulated into these micelles with high efficacy and are accommodated in the hydrophobic nanodomains. The MET nanoparticles are stable and small (~50 nm). Molecular dynamics simulations demonstrate that the material is encapsulated in a very dynamic fashion, which facilitates drug release across barriers.
NM133 is a nano enabled form of cyclosporine A that is being investigated for the treatment of dry eye. Cyclosporine A is an immunosuppressant that helps tear secretion and improve tear film stability which improves the symptoms of Dry Eye Syndrome patients. (Mantelli F, Massaro-Giordano M, Macchi I, Lambiase A, Bonini S. The cellular mechanisms of dry eye: from pathogenesis to treatment. J Cell Physiol. 2013; 228(12): 2253-6.) However, regardless of cyclosporine A’s benefits, it is an extremely hydrophobic drug. Hydrophobic means it “hates water” and simply does not mix with water. For that reason, ophthalmic formulations of cyclosporine typically rely on an oil-in-water emulsion for drug delivery into the tissues of the eye. NM133 offers a completely new approach to the delivery of cyclosporine A. Using the patent-protected MET, NM133 effectively wraps and solubilizes cyclosporine A in a protective cover, helping it across the epithelial barriers of the eye.
