I. United States Provisional Patent Application No. 62/077,622 filed Nov. 10, 2014, “Topical Sodium Nitrite Formulations”, [HHS Ref. No. E-149-2014-0-US-01];

II. International Patent Application No. PCT/US2015/060015 filed Nov. 10, 2015, “Topical Sodium Nitrite Formulations”, [HHS Reference No. E-149-2014-0-PCT-02];

III. European National Stage Patent Application No. 15798623.3, filed Nov. 10, 2015, “Topical Sodium Nitrite Formulations”, [HHS Ref. No. E-149-2014-0-EP-03];

IV. U.S. National Stage Patent Application No. 15/525,557 filed May 9, 2017, “Topical Sodium Nitrite Formulations”, [HHS Ref. No. E-149-2014-0-US-04];

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 the United States only and the field of use may be limited to the following:

“Treatment of neuropathic and/or ischemic skin ulcers in humans”.

This technology discloses a topical ointment formulation comprising about .5% to 3.0% by weight non-acidified sodium nitrite dispersed in white petrolatum, mineral oil and bisabolol for topical administration. Nitrite anions may act as a vasodilator in vivo by generating nitric oxide (NO) in tissues with lower oxygen tension and pH. Therapeutic application of sodium nitrite through this specific topical formulation may provide selective vasodilation to hypoxemic tissue that treat ulcers associated with chronic ischemic and neuropathic ulcer conditions associated with several diseases.

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.
