The prospective exclusive license territory may be “worldwide”, and the field of use may be limited to the following:
“Commercial development of mifepristone and analogues for treatment of hypercortisolism-related insulin resistance disorders in humans”
The subject technology describes a method of treating or ameliorating insulin sensitivity disorders using glucocorticoid receptor antagonist (GRA), like mifepristone, to block the metabolic side effects of cortisol, which is a key driver of hepatic and adipose insulin resistance. The invention relates to a specific dosing approach that restricts dosage to avoid over-activating the hypothalamic-pituitary-adrenal (HPA) axis and ensure cortisol safety levels.
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 Institute of Diabetes and Digestive and Kidney Diseases 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.
Complete applications for a license that are timely filed in response to this notice will be treated as objections to the grant of the contemplated exclusive patent license. 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 confidential business 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.
