Claims
exact text as granted — not AI-modified1 : A combination comprising an anti-CD19 antibody and a BCL-2 inhibitor, for use in the treatment of a patient suffering from non-Hodgkin's lymphoma, chronic lymphocytic leukemia and/or small lymphocytic lymphoma, wherein said anti-CD19 antibody is administered at least 7 days prior to the first administration of said BCL-2 inhibitor.
2 : A combination according to claim 1 , wherein the anti-CD19 antibody is administered weekly, bi-weekly or monthly after a first administration on Day 1 and wherein the BCL-2 inhibitor is administered for the first time on Day 8.
3 : A combination according to claim 1 , wherein the anti-CD19 antibody after a first administration on Day 1 is administered weekly for the first 3 months.
4 : A combination according to claim 3 , wherein the anti-CD19 antibody after a first administration on Day 1 is administered weekly for the first 3 months and bi-weekly for at least the next 3 months.
5 : A combination according to claim 4 , wherein the anti-CD19 antibody after a first administration on Day 1 is administered weekly for the first 3 months, bi-weekly for the next 3 months and monthly thereafter.
6 : A combination according to claim 2 , wherein there is an additional dosing of the anti-CD19 antibody on Day 4.
7 : A combination according to claim 2 , wherein the BCL-2 inhibitor is administered for the first time on Day 8 with a starting dose of 20 mg followed by a weekly ramp-up dosing of 50 mg, 100 mg, 200 mg and 400 mg followed by a daily dosing of 400 mg.
8 . (canceled)
9 : A combination according to claim 1 , wherein said BCL-2 inhibitor is venetoclax.
10 : A combination according to claim 1 , wherein the anti-CD19 antibody comprises an HCDR1 region comprising sequence SYVMH (SEQ ID NO: 1), an HCDR2 region comprising sequence NPYNDG (SEQ ID NO: 2), an HCDR3 region comprising sequence GTYYYGTRVFDY (SEQ ID NO: 3), an LCDR1 region comprising sequence RSSKSLQNVNGNTYLY (SEQ ID NO: 4), an LCDR2 region comprising sequence RMSNLNS (SEQ ID NO: 5), and an LCDR3 region comprising sequence MQHLEYPIT (SEQ ID NO: 6)
11 : A combination according to claim 9 , wherein the anti-CD19 antibody comprises a variable heavy chain comprising the sequence
