Abstract

Therapeutic methods of treating chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) are described. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating subtypes of CLL and SLL using a BTK inhibitor, including subtypes of CLL in patients sensitive to thrombosis and subtypes of CLL that increase monocytes and NK cells in peripheral blood after treatment with a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a combination of a BTK inhibitor and an anti-CD20 antibody.

First claim

We claim:

1. A method of treating diffuse large B-cell lymphoma (DLBCL) in a human subject suffering therefrom, comprising the step of orally administering, to the human subject, a dose of 100 mg twice daily of a Bruton's tyrosine kinase (BTK) inhibitor, wherein the BTK inhibitor is a compound of Formula (II):

or a pharmaceutically acceptable salt, solvate, or hydrate thereof.

2. The method of claim 1 , wherein the BTK inhibitor is a compound of Formula (II):

or a pharmaceutically acceptable salt thereof.

3. The method of claim 2 , wherein the BTK inhibitor is administered to the human subject for a period selected from the group consisting of about 14 days, about 28 days, and about 56 days.

4. The method of claim 2 , wherein the DLBCL is activated B-cell like diffuse large B-cell lymphoma (DLBCL-ABC).

5. The method of claim 2 , wherein the DLBCL is germinal center B-cell like diffuse large B-cell lymphoma (DLBCL-GCB).

6. The method of claim 2 , further comprising the step of administering a therapeutically effective dose of an anti-CD20 antibody selected from the group consisting of rituximab, obinutuzumab, ofatumumab, veltuzumab, tositumomab, ibritumomab, and fragments, derivatives, conjugates, variants, radioisotope-labeled complexes, and biosimilars thereof.

7. The method of claim 2 , further comprising the step of administering a therapeutically effective dose of an anticoagulant or antiplatelet active pharmaceutical ingredient.

8. The method of claim 7 , wherein the anticoagulant or antiplatelet active pharmaceutical ingredient is selected from the group consisting of acenocoumarol, anagrelide, anagrelide hydrochloride, abciximab, aloxiprin, antithrombin, apixaban, argatroban, aspirin, aspirin with extended-release dipyridamole, beraprost, betrixaban, bivalirudin, carbasalate calcium, cilostazol, clopidogrel, clopidogrel bisulfate, cloricromen, dabigatran etexilate, darexaban, dalteparin, dalteparin sodium, defibrotide, dicumarol, diphenadione, dipyridamole, ditazole, desirudin, edoxaban, enoxaparin, enoxaparin sodium, eptifibatide, fondaparinux, fondaparinux sodium, heparin, heparin sodium, heparin calcium, idraparinux, idraparinux sodium, iloprost, indobufen, lepirudin, low molecular weight heparin, melagatran, nadroparin, otamixaban, parnaparin, phenindione, phenprocoumon, prasugrel, picotamide, prostacyclin, ramatroban, reviparin, rivaroxaban, sulodexide, terutroban, terutroban sodium, ticagrelor, ticlopidine, ticlopidine hydrochloride, tinzaparin, tinzaparin sodium, tirofiban, tirofiban hydrochloride, treprostinil, treprostinil sodium, triflusal, vorapaxar, warfarin, warfarin sodium, ximelagatran, salts thereof, solvates thereof, hydrates thereof, and combinations thereof.

9. The method of claim 2 , wherein the free form of the compound of Formula (II) is administered to the human subject.

10. The method of claim 2 , wherein the pharmaceutically acceptable salt of the compound of Formula (II) is administered to the human subject.
