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

(I) The development and commercialization of glypican-3 (GPC3) antibody-based radionuclide conjugates comprising of at least:

a. The complementary determining region (CDR) sequences of the anti-GPC3 antibody known as HN3, and

b. A radionuclide, including but not limited to an alpha, beta, positron, gamma or auger emitting radionuclide, for the treatment of GPC3-expressing cancers.

(II) The development of an FDA-approved in vivo radiopharmaceutical, using a binder having the CDR sequences of the anti-GPC3 antibody known as HN3, for the diagnosis and monitoring of GPC3-expressing cancers.

The licensed field of use excludes any (a) non-specified immunoconjugates, including, but not limited to, chimeric antigen receptors (CARs) and variants thereof, immunotoxins, and antibody drug conjugates, and (b) unconjugated antibodies.

This technology discloses monoclonal antibodies that are specific for the cell surface domain of GPC3. These antibodies can potentially be used for the treatment of GPC3-expressing cancers such as HCC. In the subject situation, the antibodies can be used in conjunction to target a radionuclide specifically to GPC3-expressing cells, leading to the selective destruction of the cancerous cells.

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.
