Use of inhibitors of Bruton's tyrosine kinase (Btk)
View Patent ↗Disclosed herein are methods for treating a cancer comprising: a. administering a Btk inhibitor to a subject sufficient to result in an increase or appearance in the blood of a subpopulation of lymphocytes defined by immunophenotyping; b. determining the expression profile of one or more biomarkers from one or more subpopulation of lymphocytes; and c. administering a second agent based on the determined expression profile.
1. A method for treating relapsed or refractory chronic lymphocytic leukemia or relapsed or refractory small lymphocytic leukemia in an individual comprising administering to the individual in need thereof once per day between about 280 mg to about 840 mg of an oral dose of an irreversible inhibitor of Bruton's tyrosine kinase (Btk), having the structure:
2. The method of claim 1 , wherein the subject has high risk relapsed or refractory chronic lymphocytic leukemia.
3. The method of claim 1 , wherein the subject has nucleic acid deletion in chromosome 17.
4. The method of claim 3 , wherein the deletion is in 17p.
5. The method of claim 4 , wherein the deletion is in 17p13.
6. The method of claim 1 , wherein the subject has nucleic acid deletion in chromosome 11.
7. The method of claim 6 , wherein the deletion is in 11q.
8. The method of claim 7 , wherein the deletion is in 11q22.
9. The method of claim 1 , further comprising administering to the individual an additional cancer treatment regimen.
10. The method of claim 9 , wherein the additional cancer treatment regimen comprises bendamustine, bortezomib, CAL-101, chlorambucil, cyclophosphamide, dexamethasone, docetaxel, doxorubicin, endostatineverolimus, etoposide, fludarabine, fostamatinib, hydroxydaunorubicin, ibritumomab, ifosphamide, lenalidomide, mesalazine, ofatumumab, paclitaxel, pentostatin, prednisone, rituximab, temsirolimus, thalidomide, tositumomab, vincristine, or a combination thereof.
11. The method of claim 1 , further comprising administering to the individual rituximab.
12. The method of claim 1 , further comprising administering to the individual bendamustine.
13. The method of claim 1 , further comprising administering to the individual rituximab and bendamustine.
14. The method of claim 1 , further comprising administering to the individual rituximab, fludarabine and cyclophosphamide.
15. The method of claim 1 , further comprising administering to the individual rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone.
16. The method of claim 1 , wherein the Btk inhibitor is administered orally.
17. The method of claim 1 , wherein the Btk inhibitor is in the form of a solid oral dosage form.
18. The method of claim 1 , wherein the once per day oral dose of the Btk inhibitor administered is about 280 mg/day, about 420 mg/day, about 560 mg/day, or about 840 mg/day.
