Intellectual Property (Patent Estate)

HHS Ref. No. E-024-2018-0, U.S. Provisional Patent Application 62/590,824 filed November 27, 2017, International Patent Application PCT/US2018/062593 filed November 27, 2018, Chinese Patent Application 201880076753.7 filed November 27, 2018, European Patent Application 18816451.1 filed November 27, 2018, Israeli Patent Application 274529 filed November 27, 2018 and U.S. Patent Application 16/765,420 filed May 19, 2020, and any and all continuation or divisional applications claiming priority to any of the above.

The patent rights in these inventions have been assigned or exclusively licensed to the Government of the United States of America.

The aforementioned patent estate covers methods of treating or preventing periodontal disease in a subject by administering an inhibitor of ENPP1. In addition, the claims cover pharmaceutical compositions for use in the treatment or prevention of periodontal disease, or for increasing cementum formation. In particular, the dependent claims cover ENPP1 inhibitors comprising analogues of ATP derivatives, wherein the ENPP1 inhibitor is bound to nanoparticles, nanofibers, suture materials, microspheres, polymers, fibers, matrices, gels, or a combination thereof. The treatment methods also include dependent claims wherein treating or preventing periodontal disease comprises increasing cementum formation and wherein the composition is formulated for injection in gum tissue, local delivery at a surgical flap, buccal delivery, delivery by a resorbable suture, delivery by a wound healing dressing, or a combination of the foregoing.

Inhibition of the glycoprotein ENPP1 promotes cementum formation in mammals. Cementum, an avascular mineralized tooth root structure, attaches the tooth to the periodontal ligament and supporting bone. Cementum has limited turnover and subjects with periodontal disease experience localized loss of cementum resulting in the detachment of the periodontal ligament from the tooth root. Increasing cementum formation can be used to treat periodontal disease.

The prospective exclusive license territory may be worldwide and in a field of use that may be limited to Therapeutics for periodontitis or gingivitis, and where the “Licensed Products” are expected to be inhibitors of ecto-nucleotide pyrophosphate/phosphodiesterase-I (ENPP1) within the scope of the Licensed Patent Rights.

This notice is made in accordance with 35 U.S.C. 209 and 37 CFR part 404. The prospective exclusive patent commercialization license will be royalty bearing. The prospective exclusive license may be granted unless within fifteen (15) days from the date of this published notice, the National Heart, Lung, and Blood Institute Office of Technology Transfer and Development 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.
