Nanomerics Secures US Patent Extending MET Platform Protection to the 2040s

Patent grant reinforces long-term US protection of the MET platform underpinning Nanomerics' ocular and nose-to-brain drug delivery pipelines.

LONDON, UK / ACCESS Newswire / April 22, 2026 / Nanomerics Ltd., a clinical-stage speciality pharmaceutical company, today announced the grant of US Patent No. 12,606,641. This grant extends the protection of Nanomerics' Molecular Envelope Technology (MET) intellectual property rights to the 2040s. The grant follows the earlier grant of the corresponding European patent, with further applications pending in other jurisdictions.

Nanomerics' MET is the first clinical-stage, non-irritant, topical ocular penetration enhancer. This drug delivery technology effectively solubilises hydrophobic drugs and delivers them efficiently to both the anterior and posterior ocular tissues via topical eye drops. Nanomerics' MET underpins Nanomerics' ocular pipeline, including the clinical-stage OC134. OC134 is in development for ocular surface conditions including moderate-to-severe allergic conjunctivitis and dry eye disease.

Nanomerics' MET also delivers molecules preferentially to the brain via the nose-to-brain route, bypassing the blood-brain barrier. MET has enabled investigational products in moderate-to-severe pain and in the treatment of childhood epilepsies. Its METfect technology has demonstrated extensive pharmacological effects of various nucleic acid based therapies in the CNS.

Nanomerics' Chief Executive Officer, Professor Andreas G. Schätzlein, said:

"This US grant secures the platform foundation for our current and future MET-based products and reinforces the commercial case we are building with partners."
