Abstract

The present disclosure provides a humanized anti-CD37 small modular immunopharmaceutical (SMIP) molecule, as well as synergistic combination therapies of CD37-specific binding molecules (such as anti-CD37 SMIP proteins or antibodies) with bifunctional chemotherapeutics (such as bendamustine) that can be administered concurrently or sequentially, for use in treating or preventing B-cell related autoimmune, inflammatory, or hyperproliferative diseases.

Claims (14)

1. A humanized CD37-specific binding molecule, comprising from amino terminus to carboxyl terminus:

(i) a humanized heavy chain variable region,

(ii) a linker as set forth in SEQ ID NO:229,

(iii) a humanized light chain variable region,

(iv) an IgG1 hinge,

(v) a human IgG1 CH2 region, and

(vi) a human IgG1 CH3 region,

wherein

(a) the humanized heavy chain variable region comprises from amino terminus to carboxyl terminus: a human heavy chain FR1, a heavy chain CDR1 as set forth in SEQ ID NO:63, a human heavy chain FR2, a heavy chain CDR2 as set forth in SEQ ID NO:65, a human heavy chain FR3, a heavy chain CDR3 as set forth in SEQ ID NO:67, 68 or 69, and a human heavy chain FR4, and

(b) the humanized light chain variable region comprises from amino terminus to carboxyl terminus: a human light chain FR1, a light chain CDR1 as set forth in SEQ ID NO:61 or 62, a human light chain FR2, a light chain CDR2 as set forth in SEQ ID NO:64, a human light chain FR3, and a light chain CDR3 as set forth in SEQ ID NO:66, and a human light chain FR4.

2. The humanized CD37-specific binding molecule of claim 1 , wherein the human heavy chain FR1 comprises SEQ ID NO:144, the human heavy chain FR2 comprises SEQ ID NO:151, the human heavy chain FR3 comprises SEQ ID NO:158, and the human heavy chain FR4 comprises SEQ ID NO:161 or 162.

3. The humanized CD37-specific binding molecule of claim 1 , wherein the human light chain FR1 comprises SEQ ID NO:171, the human light chain FR2 comprises SEQ ID NO:182, the human light chain FR3 comprises SEQ ID NO:195, and the human light chain FR4 comprises SEQ ID NO:206.

4. A composition comprising a humanized CD37-specific binding molecule according to claim 1 and a pharmaceutically acceptable carrier.

5. The humanized CD37-specific binding molecule of claim 1 , wherein the human heavy chain FR1 comprises SEQ ID NO:144, the human heavy chain FR2 comprises SEQ ID NO:151, the human heavy chain FR3 comprises SEQ ID NO:158, and the human heavy chain FR4 comprises SEQ ID NO:161 or 162, the human light chain FR1 comprises SEQ ID NO:171, the human light chain FR2 comprises SEQ ID NO:182, the human light chain FR3 comprises SEQ ID NO:195, and the human light chain FR4 comprises SEQ ID NO:206.
