Intellectual Property

U.S. provisional patent application No. 62/899,899 and entitled, “Druggable Targets to Treat Retinal Degeneration” filed September 13, 2019 (E-227-2017-US-01); International Patent Application No.: PCT/US2020/050540 and entitled, “Druggable Targets to Treat Retinal Degeneration” filed September 11, 2020 (E-227-2017-PCT-02); and U.S. and foreign patent applications claiming priority to the aforementioned applications.

The patent rights in these inventions have been assigned to the government of the United States of America.

The prospective exclusive license territory may be worldwide, and the field of use may be limited to rights to develop, make use and sell, a direct ocular-administered formulation of metformin for use as therapeutics to treat retinal degenerative diseases in human.

Metformin administration to Retinal Pigment Epithelium (“RPE”) cells derived from age-related macular degeneration patients and to RPE cells derived from Stargart's-patients shows reduced accumulations of disease associated retinal deposits, suggesting clinical treatment value for metformin in retinal degenerative diseases. Metformin is FDA approved for the treatment of diabetes. No formulation of metformin is available for direct ocular use. Development of a direct ocular delivery metformin formulation could provide improved treatment effects for retinal degenerative diseases, without major systemic side effects.

This notice is made in accordance with 35 U.S.C. 209 and 37 CFR part 404. The prospective exclusive license will be royalty bearing, and the prospective exclusive license may be granted unless within fifteen (15) days from the date of this published notice, the National Cancer Institute receives written evidence and argument that establishes that the grant of the license would not be consistent with the requirements of 35 U.S.C. 209 and 37 CFR part 404.

In response to this Notice, the public may file comments or objections. Comments and objections, other than those in the form of a license application, will not be treated confidentially, and may be made publicly available.

License applications submitted in response to this Notice will be presumed to contain business confidential information and any release of information in these license applications will be made only as required and upon a request under the Freedom of Information Act, 5 U.S.C. 552.
