Intellectual Property

United States Provisional Patent Application No. 62/202,252, filed August 7, 2015 “Near Infrared PhotoImmunoTherapy (NIR-PIT) of Suppressor Cells to Treat Cancer” [HHS Reference No. E-231-2015/0-US-01]; and

PCT Patent Application PCT/US2016/045090, filed August 2, 2016 “Near Infrared PhotoImmunoTherapy (NIR-PIT) of Suppressor Cells to Treat Cancer” [HHS Reference No. E-231-2015/0-PCT-02].

The patent rights in these inventions have been assigned and/or exclusively licensed 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 the use of Licensed Patent Rights for the following: “Use of photosensitizing antibody-fluorophore conjugate defined by the Licensed Patent Rights by itself for PhotoImmunoTherapy (PIT), or in combination with cancer therapeutic agents, to treat cancer or hyperplasia.”

This technology discloses the concept of binding an anti-foxp3+ antibody to IR700 to bind to foxp3+ T-cells. When irradiated with near infrared light localized at the site of the solid tumor, controlled local knockdown of foxp3+ negative regulatory T-cells in tumors results in rapid tumor death without the severe autoimmune response that is induced by systemic knock-down of foxp3+ T-cells. Theoretically, this technology can be used in a broad spectrum of patients with a variety of solid cancers including those with Start Printed Page 65365multiple distant metastasis as foxp3+ T-cells are generally believed to be critical to immunotolerance found in cancers. By treating a single local site with this technology, systemic host immunity against in situ cancers can be dramatically activated, leading to rapid tumor regression at the treated lesion as well as distant metastatic lesions untreated with the near infrared light while inducing minimal side effects.

The prospective exclusive license will be royalty bearing and will comply with the terms and conditions of 35 U.S.C. 209 and 37 CFR part 404.7. 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 404.7.

Complete applications for a license in the prospective field of use that are filed in response to this notice will be treated as objections to the grant of the contemplated Exclusive Patent License Agreement. Comments and objections submitted to this notice will not be made available for public inspection and, to the extent permitted by law, will not be released under the Freedom of Information Act, 5 U.S.C. 552.
