Treatment of indolent or aggressive B-cell lymphomas using a combination comprising BTK inhibitors
Disclosed herein is a method for the prevention, delay of progression or treatment of indolent or aggressive B-cell lymphomas in an individual in need thereof, comprising administering a Btk inhibitor (in particularly (S)-7-(1-actyloylpiperidin-4-yl)-2-(4-phenoxyphenyl)-4,5,6,7-tetrahydropyrazolo-[1,5-a]pyrimidine-3-carboxamide or a pharmaceutically acceptable salt thereof) in combination with an anti-PD-1 antibody. The potent and selective BTK inhibitor in combination with the anti-PD-1 antibody have a manageable toxicity profile in patients with indolent and aggressive lymphomas.
1. A method for the delay of progression or treatment of an indolent or aggressive B-cell lymphoma in a human in need thereof, comprising administering to the human a therapeutically effective amount of a BTK inhibitor, in combination with a therapeutically effective amount of an anti-PD-1 antibody or an antigen-binding fragment thereof,
wherein the BTK inhibitor is (S)-7-(1-acryloylpiperidin-4-yl)-2-(4-phenoxyphenyl)-4,5,6,7-tetra-hydropyrazolo[1,5-a]pyrimidine-3-carboxamide, or a pharmaceutically acceptable salt thereof;
and
the anti-PD-1 antibody or fragment comprises a heavy chain variable region (Vh) amino acid sequence of SEQ ID NO:24 and a light chain variable region (VI) amino acid sequence of SEQ ID NO:26.
2. The method of claim 1 , wherein the anti-PD-1 antibody or fragment comprises an IgG4 constant domain amino acid sequence of SEQ ID NO 88.
3. The method of claim 1 , wherein the indolent or aggressive B-cell lymphoma is indolent or aggressive Hodgkin's B-cell lymphoma, or indolent or aggressive non-Hodgkin's B-cell lymphoma.
4. The method of claim 3 , wherein the B-cell lymphoma is chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), mantle cell lymphoma (MCL), non-germinal center B-cell diffuse large B-cell lymphoma (non-GCB DLBCL), germinal center B-cell diffuse large B-cell lymphoma (GCB DLBCL) or DLBCL with undetermined subtype, follicular lymphoma (FL) or transformed FL, marginal zone lymphoma (MZL), Hairy cell leukemia (HCL), Richter's transformation, primary central nervous system lymphoma (PCNSL), secondary central nervous system lymphoma (SCNSL) of breast or testicular origin, transformed lymphoma, or a combination of two or more thereof.
5. The method of claim 3 , wherein the B-cell lymphoma is CLL, SLL, MCL, non-GCB DLBCL, GCB DLBCL, FL, transformed FL, MZL, HCL, or Richter's transformation.
6. The method of claim 1 , wherein the BTK inhibitor is (S)-7-(1-acryloylpiperidin-4-yl)-2-(4-phenoxyphenyl)-4,5,6,7-tetra-hydropyrazolo[1,5-a]pyrimidine-3-carboxamide.
7. The method of claim 1 , wherein the BTK inhibitor is administered orally at a dose of 320 mg QD or 160 mg BID.
8. The method of claim 7 , wherein the BTK inhibitor is administered without food.
9. The method of claim 2 , wherein the anti-PD-1 antibody is administered parenterally at a dose of 2 mg/kg Q3W to 200 mg/kg Q3W.
10. The method of claim 2 , wherein the anti-PD-1 antibody is administered parenterally at a dose of 2 mg/kg Q3W, 5 mg/kg Q3W, or 200 mg flat Q3W.
11. The method of claim 10 , wherein the anti-PD-1 antibody is administered at a dose of 200 mg flat dose every 21 days.
12. The method of claim 2 , wherein the anti-PD-1 antibody is administered intravenously.
13. The method of claim 2 , wherein the BTK inhibitor is administered at least 30 minutes before the anti-PD-1 antibody if administered on the same day.
14. The method of claim 7 , wherein the BTK inhibitor is administered with food.
15. The method of claim 1 , wherein the method is a method of delay of progression or treatment of an indolent or aggressive B-cell lymphoma; wherein the BTK inhibitor is administered orally at a dose of 320 mg QD or 160 mg BID; and wherein the anti-PD-1 antibody or fragment is administered intravenously at a dose of 2 mg/kg Q3W, 5 mg/kg Q3W, or 200 mg Q3W.
16. The method of claim 15 , wherein the anti-PD-1 antibody or fragment comprises an IgG4 constant domain amino acid sequence of SEQ ID NO 88.
