Definitions
- the present invention relates to anti-CD37 multispecific antibodies that specifically target B ceils expressing CD37 and are useful for the treatment of B-cei! malignancies and disorders.
- the anti-CD37 multispecific antibodies bind both CD37- expressing cells and the T ceil receptor complex on T cells to induce target-dependent T cell cytotoxicity, T cell activation and proliferation.
- B lymphocytes produce antibodies that bind to, and in some cases mediate destruction of, a foreign substance or pathogen.
- the human immune system and specifically the B lymphocytes of the human immune system go awry and disease results.
- B cell malignancies include Chronic Lymphocytic Leukemia (CLL) and Non-Hodgkin's lymphoma (NHL).
- CLL Chronic Lymphocytic Leukemia
- NHL Non-Hodgkin's lymphoma
- Rituximab marketed by Biogen targets the B-celi antigen CD20 and is approved as first-line therapy in CLL and NHL (as well as in the immune disorders rheumatoid arthritis, Wegener's granulomatosis and microscopic polyangiitis).
- rituximab in combination with CHOP (cyclophosphamide plus doxorubicin plus vincristine plus prednisone) is the standard therapy for patients newly diagnosed with diffuse large B- celi lymphoma, one of the most common forms of NHL, Even so, around one-third of patients will develop relapsed or refractory disease, which has a poor prognosis.
- CHOP cyclophosphamide plus doxorubicin plus vincristine plus prednisone
- CLL is a heterogeneous disease, primarily afflicting the elderly. For many years treatment for this disease has focused on palliative chemotherapy based approaches as monotherapy or in combination.
- Non-randomized and randomized trials have shown that
- chemoimmunotherapy combining rituximab with fludarabine and cyclophosphamide offers a survival advantage. See, for instance, Haliek et a/., 2008, Blood. 1 1 1 :5446-56; Hailek et a/., 2010, Lancet. 376:1 164-74; Keating et al., 2005, J. Clin. Oncol. 23:4079-88; Robak et a!., 2010, J. Clin, Oncol. 28:1756-65; Tarn et al., 2008, Blood. 1 12:975-80; and Wierda et al., 2005, J. Clin. Oncol. 23:4070-8. Although the therapy is often successful, around half of patients are either unresponsive or experience early relapse as is common with fludarabine- based chemotherapy. Moreover, many elderly patients are not candidates for
- CD37 is one such potential alternative target for antibody directed therapy.
- CD37 is a member of the tetraspanin superfamily of molecules which as a class of proteins are generally implicated in diverse processes, including cellular activation and proliferation, cell motility, and cell-ceil adhesion.
- CD37 is a heavily glycosylated ceil surface protein expressed constitutiveiy at high levels on mature human B ceils and transformed mature human B-cell leukemia and lymphoma ceils.
- CD37 is not expressed on pro-B cells or terminally differentiated plasma cells.
- CD37 is either absent or expressed weakly on normal T ceils, monocytes, and neutrophils, and is absent from natural killer (NK) cells, platelets, and erythrocytes.
- NK natural killer
- CD37 is considered to be a lineage-specific marker of mature human B cells restricted to the surface of B lymphocytes and therefore represents a unique therapeutic target. Because normal mature B-celis also express CD37, normal B-ceils are depleted by an anti-CD37 antibody (Press et a/., 1989, J. Clin. OncoL 7(3):1027-1038). After anti-CD37 treatment is completed, however, normal B-cei!s can be regenerated from CD37- negative B-celi precursors; therefore, patients treated with anti-CD37 therapy do not experience significant immunosuppression. [007] Until recently, only minimal effort has been directed toward CD37 immune therapy.
- MB-1 a murine igG1 monoclonal antibody labeled with 131 i and tested in clinical trials for therapy of NHL. See Press et a!., J, Clin. Oncol., 7(3): 1027-1038 (1989); Bernstein et al., Cancer Res. (SuppL), 50: 1017-1021 (1990); Press et al., Front. Radiat. Ther. Oncol., 24: 204-213 (1990); Press et al., Adv. Exp. Med. Biol., 303: 91 -98 (1991 ) and Brown et al., Nucl. Med. Biol., 24: 657-663 (1997).
- MB-1 lacked Fc effector functions such as antibody-dependent cellular cytotoxicity (ADCC), and it did not inhibit tumor growth in an in vivo xenograft model unless labeled with an isotope (Buchsbaum et al., Cancer Res., 52(83): 6476-6481 (1992).
- ADCC antibody-dependent cellular cytotoxicity
- 131 1- MB-1 was seen in lymphoma patients who had lower tumor burdens ( ⁇ 1 kg) and therapy of these patients resulted in complete tumor remissions lasting from 4 to 1 1 months (Press et al., 1989 and Bernstein et al. 1990).
- TRU-016 is a CD37-specific antibody-like therapeutic protein comprising, from amino to carboxyl terminus, a binding domain derived from G28-1 (i.e., scFv), an
- SMI P-016 has been shown to induce apoptosis of CLL cells in vitro in a tyrosine phosphoryiation-dependent manner that suggests an alternative signaling mechanism of action compared to rituximab.
- a recent publication demonstrated that CD37 has both !T!M and ITAM-like signaling activity, and ligation of this antigen by SMI P-016 prompts recruitment of the phosphatase SHP1 , inhibition of the PI3-kinase pathway, and up- regulation of BIM, which is responsible for apoptosis mediated by this agent.
- the unique mechanism of killing through CD37 distinct from CD20 selective binding of TRU-016 to mature B-cells and promising in vivo activity, the fully humanized TRU-016 was moved into the clinic for testing.
- TRU-016 is the furthest along in the clinic of anti-CD37 therapeutics currently in development, in one trial, fifty-seven patients were treated in the dose-escalation phase and 26 in the expansion phase. A maximum tolerated dose (MTD) was not identified. Pharmacokinetics of TRU-016 was dose-proportionai with a median terminal haif-!ife of 8 days. Clinical activity was observed with partial responses in untreated and relapsed patients including individuals with del(17p13.1 ). Specifically, lymphocyte reduction 50% was observed in 55% (46/83) of all patients treated and 19 (23%) attained a response by NCI-98 criteria. All responses were partial responses and occurred more commonly in patients with symptomatic untreated CLL (8/7) or 1 -2 prior therapies (12/29) compared to those with 3 or more therapies (1/47). TRU-018 demonstrated a favorable safety profile.
- chimeric and humanized anti-CD37 antibodies derived from murine antibody G28-1 have been developed with engineered CH2 domains for improved binding to human Fey receptors.
- One such chimeric antibody, mAb 37.1 has been reported to show high intrinsic proapoptotic activity on malignant B cells accompanied by homotypic aggregation, if has also been reported to exhibit Ab-mediated high Ab-dependent cell- mediated cytotoxicity (ADCC) on lymphoma and primary CLL ceils. It has been reported that mAb 37.1 strongly depleted normal B cells as well as spiked B-!ymphoma cells in blood samples from healthy donors as well as malignant B ceils in blood from CLL patients.
- ADCC Ab-mediated high Ab-dependent cell- mediated cytotoxicity
- a single dose of mAb CD37.1 administered to human CD37-transgenic mice resulted in a reversible, dose-dependent reduction of peripheral B cells.
- administration of mAb 37.1 strongly suppressed tumor growth. See, for instance, Heider ei a/., 201 1 , Blood. 1 18(15):4159-69.
- ISV1GN529 Another anti-CD37 antibody-like polypeptide in development is ISV1GN529, an antibody-drug conjugate targeting hCD37 that consists of the CD37-targeting K7153A antibody linked to the maytansinoid DM1 via the thioether S CC linker.
- I GN529 has been reported to exhibit anti-ieukemic effects in a murine model of aggressive B-cell malignancy. Based on data from an engraftment model, it is believed that IMGN529 is capable of eliminating widespread and highly proliferative mouse leukemia by a mechanism that is both CD37 antigen and conjugate dependent. See, for instance,
- TRU-016 and other antibodies and antibody-like polypeptides currently in the clinic are monospecific therapies that depend, at least partially, on ADCC activity directed through Natural Killer (NK) cells.

- Humanization is expected to result in an antibody that is less immunogenic, with complete retention of the antigen-binding properties of the original molecule.

- EXAMPLE 1 Construction of anti-CD37 x anti-CD3 multispecific homodirner antibody molecules
- SEQ ID NO:1 As a starting sequence (from amino to carboxyl terminus, a humanized scFv derived from anti-CD37 antibody G28-1 , a modified immunoglobulin igG1 hinge and wild-type lgG1 CH2 and CH3 regions). Wild-type IgGi hinge contains three cysteine residues.
- the modified !gG1 hinge of SEQ ID NQ:1 (with cysteine to serine mutations at first two cysteines) was changed to a modified lgG1 hinge with a cysteine to serine mutation at the first cysteine residue only (i.e., SCC).
- the wild-type lgG1 Fc sequence of SEQ ID NO: 1 was modified to either igG1 null2 Fc (SEQ ID NO: 102) or lgG4 N297A ADCC- Fc (SEQ ID IMG: 104) and a C-terminus linker ("H75" derived from NKG2A; SEQ ID NG:132) was added at the C-terminus of each Fc.
- These two starting sequences are named anti-CD37lgG1 nuil2 H75 and anti-CD37igG4 N297A ADCC- H75, respectively.
- These two molecules also contained the signal peptide with Hindill restriction site at the N-terminus and EcoRI restriction site at the C-terminus of the H75 linker.
- a total of 6 fragments were generated: 3 for anti-CD37 lgG1 nuN2 fragments with 3 different linkers and another 3 for anti-CD37 lgG4 N297A ADCC- fragments containing the 3 different linkers.
- These 6 PGR generated fragments were then digested with Hindi II and EcoRI restriction enzymes and ligated into the PD28 vector along with a humanized anti-CD3 scFv (SEQ ID NO:89) that had been previously digested with EcoR! and Notl in the 3 way ligation reactions.
- SEQ ID NO:89 humanized anti-CD3 scFv
- EXAMPLE 2 Binding of multispecific anti-CD37 antibodies to CD37(+ . CD37 . CD3(+V and/or CD3(-) cell lines
- binding studies could be performed on human cancer cell lines expressing CD37 (such as RajL Ramos, Daudi, DoHH2, SU-DHL-6, Rec-1 and Mino), expressing CDS (such as Jurkat and TALL-1 Q4), or negative for CD37 or CDS expression and binding determined by standard FACS-based staining procedures, A typical experiment blocks 200,000-500,000 cells per well in a 96-wel! plate with human serum or unlabeled human IgG prior to labeling cells with various concentrations of binding molecule on ice.
- CD37 such as RajL Ramos, Daudi, DoHH2, SU-DHL-6, Rec-1 and Mino
- CDS such as Jurkat and TALL-1 Q4
- a typical experiment blocks 200,000-500,000 cells per well in a 96-wel! plate with human serum or unlabeled human IgG prior to labeling cells with various concentrations of binding molecule on ice.
- Bound molecule is detected with a labeled (e.g., fluorescent), biotinyiated, or unlabeled secondary antibody directed against either the Fc region or one idiotype of the binding molecule. If the secondary antibody is not labeled, a labeled (e.g., fluorescent) streptavidin molecule or tertiary antibody is employed. Cells may also be labeled with a viability dye to exclude unhealthy ceils from the analysis. Signal from bound molecules is detected on a flow cytometer. Signal above the background derived from secondary/tertiary molecules alone indicates binding of molecules to the cell surface. Specificity of binding is demonstrated through the use of negative control binding molecules, cell lines negative for CD37 or CDS expression, or by preventing specific binding with an excess of a competitive binder targeting CD37 or CDS.
- a labeled e.g., fluorescent
- Ramos cells a CD37(+) / CD3( ⁇ ) American Burkitt's lymphoma human cell line
- Jurkat ceils a CD37(-) / CD3(+) acute T-ce!l leukemia human cell line
- Both Ramos and Jurkat ceils were from the ATCC (Manassas, VA).
- C4-2 cells a sub-line of the LNCaP human prostate cancer ceil line (negative for both CD37 and CD3 expression) was included as a negative binding control to confirm specificity of binding interactions.
- C4-2 cells were from The University of Texas MD Anderson Cancer Center (Houston, TX). Binding was assessed by standard flow cytometry staining procedures.
- RTCC T-cell cytotoxicity
- PBMC Peripheral blood mononuclear cells
- T ceils were used without stimulation and added at a 5:1 ratio (T cells : target ceils).
- CD37-expressing Ramos and CD37-negative C4-2 target ceils were loaded in culture medium with sodium chromate in saline at 0.05 mCi/million ceils. Ceils were washed and plated at 10,000 51 Cr-loaded target cells per well into 96-weli U-bottom untreated polystyrene assay plates together with T ceils and molecules in a final volume of 200 ⁇ RPMI 1640 growth medium supplemented with 10% heat-inactivated fetal bovine serum, 20 mM HEPES, 1X non-essential amino acids, 1 mM sodium pyruvate, and 55 ⁇ 2- mercaptoethano!. Cell cultures were incubated in a C0 2 incubator at 37°C for approximately 20 hours.
- Ail anti-CD37 x anti-CD3 bispecific molecules tested were capable of specifically redirecting T-ceil cytotoxicity (Figure 3). Results are representative of two independent experiments. The molecules mediated CD37-positive target ceil lysis above background in the presence of T ceils and induced only very low cytotoxicity at high concentrations of molecule on CD37 ⁇ negative target cells.
- EXAMPLE 4 Target-dependent T cell activation and proliferation induced agasnst CD37( ⁇ ) cell lines directed by muitispecific anti-CD37 antibodies
- anti-CD37 x anti-CD3 bispecific molecules were assessed in four to five day assays.
- PBMC Peripheral blood mononuclear cells
- T cells were isolated from human blood obtained from healthy donors using standard density gradient centrifugation. T cells were purified from isolated PBMC with the Pan T-cei! Isolation Kit II (Miltenyi Biotec). T cells were labeled using the CELLTRACETM CFSE Cell Proliferation Kit (Molecular Probes, Eugene, OR), an amine-reactive intracellular labeling kit used to assess proliferation by loss of fluorescence in cells that have undergone division. CFSE-labeled T cells were added to the assays without prior stimulation.
- Target cells included both CD37-expressing Ramos cells and CD37-negative C4- 2B human prostate cancer cells (The University of Texas MD Anderson Cancer Center). Target ceils were rendered non-pro!iferative by x-ray irradiation.
- CFSE-labeled T cells were plated in tissue culture treated U-bottom 96-weil plates at 100,000 cells/well with 30,000 target tumor cells/well, to achieve an effector to target cell ratio of roughly 3:1.
- test molecules were added to the ceil mixtures in a total volume of 200 ⁇ /well in RPMI 1640 growth media supplemented with 10% human serum, 1 X sodium pyruvate, 1 X non-essential amino acids, 1X L-glutamine, and 20 mM HEPES. Assay plates were incubated in humidified C0 2 incubators at 37°C. [0261] After four or five days, cells were labeled with antibodies for analysis by flow cytometry. Ceils were labeled and washed in their original plates to minimize ceil loss, and ail labeling was performed in DPBS with 0.2% bovine serum albumin and 2 m EDTA. First, cells were blocked with 100 ug/ml human IgG on ice for 20 min. and washed once.
- Ail anti-CD37 x anti-CD3 bsspecific molecules tested were capable of supporting both CD4+ and CD8+ T-ceil proliferation in the presence of CD37-positive target ceils (Figure 4).
- a subset of anti-CD37 x anti-CD3 bispecific molecules tested with T cells alone and with both CD37-positive (Ramos) and CD37 ⁇ negative (C4-2B) target cells demonstrated that non-specific T-ceil proliferation in the absence of target cells or on CD37-negative target cells was negligible (Figure 5).
- the cell division data provided in Figures 4 and 5 was measured independently from CD25 expression. Up-reguiation of cell surface CD25 is associated with T-cell activation and was observed on divided T cells (data not shown).

- EXAMPLE 8 Minimal cytokine release following redirected T cell cytotoxicity with in vitro
- PBMC peripheral blood mononuclear cells
- T ceils are purified from isolated PBMC using the Pan T ceil Isolation Kit ii from Mi!tenyi Biotec (Bergisch Gladbach, Germany) and following the manufacturer's protocol. Whole PBMC or purified T ceils are plated in U-bottom 96-we!l plates at 200,000 to 400,000 cells/well with 60,000 to 120,000 CD37-expressing tumor cell lines (such as Raji, Ramos, Daudi, DoHH2, SU-DHL-6, Rec-1 and Mino), to achieve approximate T cell to tumor ratios of 3:1.

Assay plates are incubated in humidified C0 2 incubators at 37°C, for periods of time ranging from 4 to 48 hours. Supernatants are collected and frozen or tested immediately using a multiplex assay system (Milliplex cytokine kits from Miilipore, USA) to measure cytokines predicted to be released by activated T ceils and myeloid cells.
- a multiplex assay system Milliplex cytokine kits from Miilipore, USA
- the cytokines in the analysis include but are not limited to: IL-2, IL-4, IL-5, IL-6, !L-8, !L-10, IL-12, IL-17, TNFa and IFNy. Twenty-five ⁇ volumes from each well are tested in duplicate samples and run following the manufacturer's instructions. The molecule is evaluated for the levels and types of cytokines released compared to control bispecific molecules evaluated with target cells and T ceils or PBMC and control, untreated T cells or PBMC alone.
- cytokine levels may be low compared to other control multispecific moiecuies in other formats (such as bispecific single chain antibody) that induce similar levels of T cell activation. Presence of normal B cells in cultures initiated with whole PBMC leads to some level of T cell activation in the presence of target, and therefore cytokine secretion.
- EXAMPLE 7 Tolerable, dose-dependent cytokine release following dosing of Non-Human Primates (NHP) with high doses of muitispecific anti-CD37 antibody
- the ability of the muitispecific anti-CD37 antibody to trigger RTCC function by macaque T ceils is determined on a mixture of whole NHP PBMC in the presence or absence of human CD37 + targets ceils, as described above.
- NHP T cells do not need to be purified from whole PBMC because the anti-CD37 binding domain does not cross-react with macaque CD37.
- Bispecific antibodies and other muitispecific antibodies are capable of specifically redirecting T cell cytotoxicity by the tested species if they mediate CD37-positive target cell lysis above background in the presence of T cells but not on CD37-negative target cells or in the absence of T cells.
- a comparison of the concentration of a particular muitispecific anti-CD37 antibody required to elicit half-maximum lysis by human and NHP T cells allows calculation of a multiplier to correct for functional equivalence between NHP and human RTCC function for the tested molecule.
- the molecules are tested in a mixture of PBMC in the presence or absence of human CD37 + targets cells.
- Supernatants are collected at time points ranging from 4 to 48 hrs., and frozen or tested immediately using a multiplex assay system (e.g., Miliiplex cytokine kits from Millipore, USA) to measure cytokines predicted to be released by activated T ceils and myeloid ceils.
- the cytokine release assays are performed as described above. The levels of cytokines induced by the bispecific molecule are low compared with those induced by a positive control.
- a range of doses is selected based on results from the in vitro studies.
- the maximum dose is selected based on the expected human therapeutic dose, the multiplier of functional equivalence between human and NHP, and a minimum 10-fold excess safety margin.
- the selected doses of a muitispecific anti-CD37 antibody are injected intravenously into groups of NHP.
- a vehicle control group is included to control for changes induced by formulation and animal handling. Animals are monitored for at least 2 hours following dosing for signs of cytokine release. Blood samples are drawn before dosing and periodically following dosing to obtain serum for assessment of circulating cytokines.
- cytokines in serum are determined using a multiplex assay system (e.g., Milliplex cytokine kits from Millipore, USA) as described above.
- the levels of cytokines induced by the multispecific antibody are drug-dependent, dose- dependent, and tolerable.
