End Preamble Start Supplemental Information


This technology relates to leptin, a protein hormone that plays a key role in regulating energy intake and expenditure. This hormone is released from adipose tissue and inhibits appetite in the brain by counteracting peptide hormones responsible for stimulating hunger, and also stimulates the synthesis of another peptide hormone, α-MSH, which acts as an appetite suppressant.

Lipodystrophy, a disorder characterized by pathological deposition of adipose tissue (fat), is caused by a deficiency or complete absence of leptin. Patients with severe lipodystrophy have abnormalities in adipose tissue distribution with loss of subcutaneous fat, and suffer from multiple metabolic disorders—extreme insulin resistance, very high triglyceride levels, diabetes and steatosis (fat accumulation in tissues like liver and muscle)—that are associated with increased risk of severe pancreatitis, early diabetes complications, cirrhosis and early cardiovascular death. Leptin replacement therapy in such patients leads to clear and dramatic metabolic benefits, including a reduction in insulin resistance and triglyceride levels, which are refractory to other treatment.

This technology relates to the use of leptin, a leptin analog, or a leptin derivative to treat lipoatrophy, as well as methods and kits for determining a predisposition of a lipoatrophic patient to respond to treatment with leptin, a leptin analog, or a leptin derivative.

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 404.7. The prospective exclusive license may be granted unless, within 30 days from the date of this published Notice, the NIH 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 404.7.

Applications for a license in the prospective field of use filed in response to this notice will be treated as objections to the grant of the contemplated exclusive license. Comments and objections submitted in response 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.
