Summary for Patent: 10,240,207
Title:Cancer treatment with c-met antagonists and correlation of the latter with HGF expression
Abstract: The present invention concerns cancer biomarkers. In particular, the invention concerns HGF as a biomarker for patient selection and patient prognosis in cancer, as well as methods of therapeutic treatment, articles of manufacture and methods for making them, diagnostic kits, methods of detection and methods of advertising related thereto.
Inventor(s): Yu; Wei (South San Francisco, CA), Shames; David (South San Francisco, CA), Koeppen; Hartmut (South San Francisco, CA), Phan; See (South San Francisco, CA), Rost; Sandra (South San Francisco, CA)
Assignee: Genentech, Inc. (South San Francisco, CA)
Application Number:15/272,283
Patent Claims:1. A method for treating a patient with cancer comprising administering an effective amount of a c-met antagonist to the patient if the patient's cancer is known to have a high amount of the HGF biomarker, wherein the patient's cancer is previously treated glioblastoma, wherein HGF biomarker is HGF mRNA, and HGF biomarker mRNA expression is assayable in a sample from the patient using in situ hybridization (ISH), wherein high HGF biomarker is: (a) an ISH score of 2+ and/or 3+; (b) presence of about 12 or more HGF ISH signal positive cells in the sample; or (c) 1% or more HGF ISH signal positive cells in the sample.

2. The method of claim 1, wherein the c-met antagonist is an antagonist anti-c-met antibody.

3. The method of claim 2, wherein the anti-c-met antibody comprises a (a) HVR1 comprising sequence GYTFTSYWLH (SEQ ID NO: 1); (b) HVR2 comprising sequence GMIDPSNSDTRFNPNFKD (SEQ ID NO: 2); (c) HVR3-HC comprising sequence ATYRSYVTPLDY (SEQ ID NO: 3); (d) HVR1-LC comprising sequence KSSQSLLYTSSQKNYLA (SEQ ID NO: 4); (e) HVR2-LC comprising sequence WASTRES (SEQ ID NO: 5); and (f) HVR3-LC comprising sequence QQYYAYPWT (SEQ ID NO: 6).

4. The method of claim 2, wherein the anti-c-met antibody binds an onartuzumab epitope.

5. The method of claim 2, wherein the anti-c-met antibody is onartuzumab.

6. The method of claim 2, wherein an effective amount of the anti-c-met antibody is 15 mg/kg every three weeks.

7. The method of claim 2, wherein an effective amount of the anti-c-met antibody is 10 mg/kg every two weeks.

8. The method of claim 1, wherein the c-met antagonist is one or more of crizotinib, tivantinib, carbozantinib, MGCD-265, ficlatuzumab, humanized TAK-701, rilotumumab, foretinib, h224G11, DN-30, MK-2461, E7050, MK-8033, PF-4217903, AMG208, JNJ-38877605, EMD1204831, INC-280, LY-2801653, SGX-126, RP1040, LY2801653, BAY-853474, and/or LA480.

9. The method of claim 1, wherein treatment is with an effective amount of a combination of a c-met antagonist and VEGF antagonist.

10. The method of claim 9, wherein the VEGF antagonist is an anti-VEGF antibody.

11. The method of claim 10, wherein said anti-VEGF antibody is bevacizumab.

12. The method of claim 10, wherein the anti-VEGF antibody binds the A4.6.1 epitope.

13. The method of claim 10, wherein the anti-VEGF antibody comprises a variable heavy chain (VH) and a variable light chain (VL), wherein the VH has an amino acid sequence of EVQLVESGGG LVQPGGSLRL SCAASGYTFT NYGMNWVRQA PGKGLEWVGW INTYTGEPTY AADFKRRFTF SLDTSKSTAY LQMNSLRAED TAVYYCAKYP HYYGSSHWYF DVWGQGTLVT VSS (SEQ ID NO: 14) and the VL has an amino acid sequence of DIQMTQSPSS LSASVGDRVT ITCSASQDIS NYLNWYQQKP GKAPKVLIYF TSSLHSGVPS RFSGSGSGTD FTLTISSLQP EDFATYYCQQ YSTVPWTFGQ GTKVEIKR (SEQ ID NO: 15).

14. The method of claim 10, wherein said effective amount of said anti-VEGF antibody is 10 mg/kg intravenously every two weeks.

15. The method of claim 10, wherein said effective amount of said anti-VEGF antibody is 15 mg/kg intravenously every three weeks.

16. The method of claim 10, wherein said effective amount of said anti-VEGF antibody is administered initially intravenously over 90 minutes, with subsequent infusions over 60 minutes and then 30 minutes.

17. The method of claim 10, wherein said anti-VEGF antibody is administered second to said patient at the first cycle.

18. The method of claim 10, wherein subsequent administrations of said anti-VEGF antibody are either prior to or after said c-met antagonist.

19. The method of claim 10, wherein said VEGF antagonist is administered concurrently with said c-met antagonist.

20. The method of claim 1, wherein the patient has greater PFS and/or OS relative to a patient who does not have high HGF biomarker.

21. The method of claim 1, wherein the patient is less than 50 years old.

22. The method of claim 1, wherein the patient is equal to or greater than 50 years old.

23. The method of claim 1, wherein the patient has a Karnofsky performance status of 70% to 80%.

24. The method of claim 1, wherein the patient has a Karnofsky performance status of 90% to 100%.

25. The method of claim 1, wherein the patient has greater PFS and/or OS relative to a patient who is treated with VEGF antagonist alone.
