DEPARTMENT OF HEALTH AND HUMAN SERVICES
National Institutes of Health
Prospective Grant of an Exclusive Patent License for
Commercialization: Boron Neutron Capture Therapy for Skin Cancer
AGENCY: National Institutes of Health, HHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: This is notice, in accordance with 35 U.S.C. 209(c)(1) and 37
CFR 404.7(a)(1)(i), that the National Institutes of Health (NIH),
Department of Health and Human Services, is contemplating the grant of
a worldwide exclusive license to practice the inventions embodied in:
HHS Ref. No. E-135-2015/0, U.S. Provisional Patent Application No. 62/
155,085, filed April 30, 2015, entitled ``Boron Mimics Of Amino Acids
And Uses Thereof,'' to Beijing Lanyears Communication Technology, Ltd.,
a company formed under the laws of the People's Republic of China and
having its principle place of business in Beijing, China.
The contemplated exclusive license may be limited to boron neutron
capture therapy for skin cancer.
DATES: Only written comments and/or applications for a license that are
received by NIH at the address indicated below on or before April 21,
2016 will be considered.
ADDRESSES: Requests for a copy of any unpublished patent application,
inquiries, objections to this notice, comments and other requests
relating to the contemplated license should be directed to: Michael
Shmilovich, Esq., CLP, Senior Licensing and Patent Manager, 31 Center
Drive, Room 4A29, MSC2479, Bethesda, MD 20892-2479, phone number 301-
435-5019, or [email protected].
SUPPLEMENTARY INFORMATION: The invention pertains to boramino acid
compounds that can be used as imaging agents for positron emission
tomography of cancer or for boron neutron capture therapy. Mimetics
created by substituting the carboxylate group (-COO-) of an amino acid
with trifluoroborate (-BF3-) are metabolically stable and allow for the
use of fluorine-18 (\18\F) as the radiolabel (e.g., trifluoroborate
phenylalanine (B-Phe)). Using boramino acid for \18\F-labeling allows
for integrating the \18\F radiolabel into the core molecular backbone
rather than the side-chains thus increasing the agent's target
specificity. There is a direct relationship between amino acid uptake
and cancer cell replication, where the uptake is extensively
upregulated in most cancer cells. This uptake increases as cancer
progresses, leading to greater uptake in high-grade tumors and
metastases. Amino acids act as signaling molecules for proliferation
and may also reprogram metabolic networks in the buildup of biomass.
This invention provides for an unmet need for traceable amino acid
mimics, including those based on naturally-occurring amino acids, which
may be non-invasively detected by imaging technology, including for
clinical diagnosis or BNCT. Boron neutron capture therapy (BNCT) is
based on the nuclear capture and fission reactions that occur when non-
radioactive boron-10 (\10\B, approximately 20% of natural elemental
boron), is irradiated and thus activated with neutrons of the
appropriate energy to yield excited boron-11 (\11\B*). This isotope
turn

decays into high energy alpha particles (``stripped'' down \4\He
nuclei) and high energy lithium-7 (\7\Li) nuclei. Both the emitted
alpha particles and the lithium ions are close proximity reactions,
i.e., at a range of approximately 5-9 [micro]m; the diameter of a
target cell. The energies produced in this ionization and radio-decay
is cytotoxic and thus exploited as the basis for cancer radiotherapy.
The success of BNCT is dependent on the selective delivery of
sufficient amounts of \10\B to the tumor site with only small amounts
localized in the surrounding normal tissues thus sparing normal tissue
from the nuclear capture and fission reactions.
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 fifteen
(15) days from the date of this published notice, 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.
Properly filed competing applications for a license filed in
response to this notice will be treated as objections to the
contemplated 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.
Dated: April 1, 2016.

Development, National Heart, Lung, and Blood Institute.
