Abstract

The invention relates to binding molecules that bind specifically to prostate specific membrane antigen (PSMA), in particular, single human variable heavy chain domain antibodies and related methods for treatment of cancer.

Claims (32)

1. A binding molecule capable of binding human PSMA comprising a single human variable heavy chain domain (V H ) antibody comprising CDR1, CDR2 and CDR3 sequences selected from

a CDR1 sequence comprising SEQ ID NO. 1, a CDR2 sequence comprising SEQ ID NO. 2 and a CDR3 sequence comprising SEQ ID NO. 3, or

a CDR1 sequence comprising SEQ ID NO. 5, a CDR2 sequence comprising SEQ ID NO. 6 and a CDR3 sequence comprising SEQ ID NO. 7, or

a CDR1 sequence comprising SEQ ID NO. 9, a CDR2 sequence comprising SEQ ID NO. 10 and a CDR3 sequence comprising SEQ ID NO. 11, or

a CDR1 sequence comprising SEQ ID NO. 13, a CDR2 sequence comprising SEQ ID NO. 14 and a CDR3 sequence comprising SEQ ID NO. 15, or

a CDR1 sequence comprising SEQ ID NO. 17, a CDR2 sequence comprising SEQ ID NO. 18 and a CDR3 sequence comprising SEQ ID NO. 19, or

a CDR1 sequence comprising SEQ ID NO. 21, a CDR2 sequence comprising SEQ ID NO. 22 and a CDR3 sequence comprising SEQ ID NO. 23, or

a CDR1 sequence comprising SEQ ID NO. 25, a CDR2 sequence comprising SEQ ID NO. 26 and a CDR3 sequence comprising SEQ ID NO. 27, or

a CDR1 sequence comprising SEQ ID NO. 29, a CDR2 sequence comprising SEQ ID NO. 30 and a CDR3 sequence comprising SEQ ID NO. 31, or

a CDR1 sequence comprising SEQ ID NO. 33, a CDR2 sequence comprising SEQ ID NO. 34 and a CDR3 sequence comprising SEQ ID NO. 35, or

a CDR1 sequence comprising SEQ ID NO. 37, a CDR2 sequence comprising SEQ ID NO. 38 and a CDR3 sequence comprising SEQ ID NO. 39, or

a CDR1 sequence comprising SEQ ID NO. 41, a CDR2 sequence comprising SEQ ID NO. 42 and a CDR3 sequence comprising SEQ ID NO. 43, or

a CDR1 sequence comprising SEQ ID NO. 45, a CDR2 sequence comprising SEQ ID NO. 46 and a CDR3 sequence comprising SEQ ID NO. 47, or

a CDR1 sequence comprising SEQ ID NO. 49, a CDR2 sequence comprising SEQ ID NO. 50 and a CDR3 sequence comprising SEQ ID NO. 51, or

a CDR1 sequence comprising SEQ ID NO. 53, a CDR2 sequence comprising SEQ ID NO. 54 and a CDR3 sequence comprising SEQ ID NO. 55, or

a CDR1 sequence comprising SEQ ID NO. 57, a CDR2 sequence comprising SEQ ID NO. 58 and a CDR3 sequence comprising SEQ ID NO. 59, or

a CDR1 sequence comprising SEQ ID NO. 61, a CDR2 sequence comprising SEQ ID NO. 62 and a CDR3 sequence comprising SEQ ID NO. 63, or

a CDR1 sequence comprising SEQ ID NO. 65, a CDR2 sequence comprising SEQ ID NO. 66 and a CDR3 sequence comprising SEQ ID NO. 67, or

a CDR1 sequence comprising SEQ ID NO. 69, a CDR2 sequence comprising SEQ ID NO. 70 and a CDR3 sequence comprising SEQ ID NO. 71, or

a CDR1 sequence comprising SEQ ID NO. 73, a CDR2 sequence comprising SEQ ID NO. 74 and a CDR3 sequence comprising SEQ ID NO. 75, or

a CDR1 sequence comprising SEQ ID NO. 77, a CDR2 sequence comprising SEQ ID NO. 78 and a CDR3 sequence comprising SEQ ID NO. 79.

2. The binding molecule of to claim 1 wherein said V H domain comprises or consists of SEQ ID NO. 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, 76 or 80.

3. The binding molecule of claim 1 wherein said binding molecule comprises two or more single V H domain antibodies wherein at least one of the single V H domain antibodies binds specifically to PSMA.

4. The binding molecule of claim 1 wherein said binding molecule is conjugated to a toxin, enzyme, radioisotope or other chemical moiety.

5. The binding molecule of claim 1 obtained or obtainable from a mouse that does not produce any functional endogenous light or heavy chains.

6. The binding molecule of claim 1 conjugated to a moiety.

7. The binding molecule of claim 6 wherein said moiety is a toxin.

8. A pharmaceutical composition comprising the binding molecule of claim 1 and a pharmaceutical carrier.

9. A method for treating prostate cancer or a PSMA-expressing cancer comprising administering a therapeutically-effective amount of the binding molecule of claim 1 .

10. The binding molecule of claim 6 wherein said moiety binds human serum albumin.

11. The binding molecule of claim 6 wherein said moiety is a single V H domain antibody that binds an immunooncology target.

12. A method for treating prostate cancer or a PSMA-expressing cancer comprising administering a therapeutically-effective amount of the pharmaceutical composition of claim 8 .
