The fully human monoclonal antibody PAT-SC1 is specific for an isoform of CD55 (decay-accelerating factor) designated CD55PAT-SC1. This antigen is expressed in the majority (80%) of gastric cancers (GCs), and the antibody induces tumour cell-specific apoptosis in vitro as well as in vivo. PAT-SC1, therefore, has been deemed promising as a therapeutic agent. Here, we describe the results of an academic clinical study performed in a neoadjuvant setting with resectable GC patients. Patients undergoing treatment for GC between 1997 and 2001 were tested for CD55PAT-SC1 expression. Fifty-one resectable patients that tested positively received a single administration of 20 mg PAT-SC1 48 h prior to surgery. They underwent standard surgery with either subtotal or total gastrectomy with bursectomy, omentectomy and a modi- fied D2-lymphadenectomy, aimed at R0 resection. Primary endpoints of the present study were to evaluate side-effects of the PAT-SC1 antibody treatment and to evaluate histopathological effects such as tumour regression and induction of apoptosis. Long-term survival was a secondary endpoint. Administration of PAT-SC1 appeared safe with only reversible side-effects according to WHO grade I and II. Despite the low-dose of the antibody, 81.6% of the patients showed signs of increased apoptosis within the primary tumour and 60% showed signs of tumour cell regression. Comparison of the 10-year survival rates of the R0-resected CD55PAT-SC1-positive patients treated with the PAT-SC1 antibody with a historical collective of R0-resected CD55PAT-SC1- positive patients not treated with PAT-SC1 indicated a survival benefit in the treated patients. Furthermore, comparison of the patient survival of CD55 PAT-SC1-positive vs. CD55PAT-SC1-negative groups suggested that CD55PAT-SC1 antigen expression is an independent predictor of poor survival in a Cox regression analysis. Antibody PAT-SC1 may be a useful additive therapeutic agent in the treatment of patients with CD55 PAT-SC1-expressing GCs. In combination with radical standard surgery, PAT-SC1 given as an adjuvant or neoadjuvant immunotherapeutic agent induces apoptosis in tumour cells which may improve survival of these patients. Because of the human origin and its specific binding to the CD55PAT-SC1 antigen, PAT-SC1 was well tolerated in this trial.

The primary objective of this phase 1 study was to evaluate the safety and tolerability of the anti-glucose regulated protein 78 monoclonal immunoglobulin M antibody PAT-SM6 in subjects with relapsed or refractory multiple myeloma. Twelve heavily pretreated patients received four intravenous infusions of PAT-SM6 at doses of 0.3, 1, 3, and 6 mg/kg within 2 weeks. Efficacy, pharmacokinetics and immunogenicity were followed up until the end of the trial (day 36). In addition, immune cell patterns in peripheral blood were assessed by flow cytometry and glucose regulated protein 78 expression status was evaluated in bone marrow specimens by immunohistochemistry and flow cytometry at screening. All doses administered were found to be safe and well tolerated; the maximum tolerated dose was not reached. The most common treatment emergent adverse event was leukopenia (grades 1 and 2) in eight out of the 12 multiple myeloma patients. Pharmacokinetic analysis demonstrated dose-proportional increases in drug serum concentration. The terminal half-life ranged from 5.86 to 8.41 h, the apparent volume of distribution ranged from 101 to 150 mL/kg, and clearance ranged from 8.11 to 16.1 mL/h/kg. All patients showed glucose regulated protein 78 surface expression on multiple myeloma cells. Four out of the 12 patients (33.3%) had stable disease, according to the International Myeloma Working Group criteria, after PAT-SM6 treatment across the doses 1, 3 and 6 mg/kg. In summary, single-agent PAT-SM6 was well tolerated with modest clinical activity in relapsed or refractory multiple myeloma. Further trials exploring the combination of PAT-SM6 with existing myeloma therapies are planned. Trial registration: clinicaltrials.gov identifier:NCT01727778 © 2015 Ferrata Storti Foundation.

The monoclonal IgM antibody PAT-SM6 derived from human tumours induces apoptosis in tumour cells and is considered a potential anti-cancer agent. A primary target for PAT-SM6 is the unfolded protein response regulator GRP78, over-expressed externally on the cell surface of tumour cells. Small angle X-ray scattering (SAXS) studies of human GRP78 showed a two-domain dumbbell-shaped monomer, while SAXS analysis of PAT-SM6 revealed a saucer-shaped structure accommodating five-fold symmetry, consistent with previous studies of related proteins. Sedimentation velocity analysis of GRP78 and PAT-SM6 mixtures indicated weak complex formation characterized by dissociation constants in the high micromolar concentration range. In contrast, enzyme-linked immunosorbant assays (ELISAs) showed strong and specific interactions between PAT-SM6 and immobilized GRP78. The apparent binding constant estimated from a PAT-SM6 saturation curve correlated strongly with the concentration of GRP78 used to coat the microtiter tray. Experiments using polyclonal antiGRP78 IgG antibodies or a monoclonal IgG derivative of PAT-SM6 did not show a similar dependence. Competition experiments with soluble GRP78 indicated more effective inhibition of PAT-SM6 binding at low GRP78 coating concentrations. These observations suggest an avidity-based binding mechanism that depends on the multi-point attachment of PAT-SM6 to GRP78 clustered on the surface of the tray. Analysis of ELISA data at high GRP78 coating concentrations yielded an apparent dissociation constant of approximately 4 nM. We propose that the biological action of PAT-SM6 in tumour cell apoptosis may depend on the multivalent nature of PAT-SM6 and the high avidity of its interaction with multiple GRP78 molecules clustered on the tumour cell surface. © 2012 Rosenes et al.

Human hybridoma technologies permit the cloning of patient antibodies that may have desirable qualities. In this study, we report the isolation of a natural IgG antibody from a stomach cancer patient that illustrates novel diagnostic and therapeutic uses. Human antibody PAT-BA4 recognizes a tumor-specific variant of the transcription factor TATA-binding protein-associated factor 15 (TAF15) that is expressed on the plasma membrane of stomach cancer and melanoma cells but not healthy tissues. TAF15 is a member of the multifunctional TET protein family involved in mRNA transcription, splicing, and transport that is normally expressed only in the cytoplasm and nucleus of fetal or adult tissue cells. However, in malignant cells, TET family members including TAF15 seem to be involved in cell adhesion and spreading. In support of this likelihood, we found that PAT-BA4 inhibited tumor cell motility and tumor cell adhesion. Our findings define a role for a tumor-specific TAF15 antigen in malignant processes. ©2010 AACR.

Despite the recent development of novel therapies for patients with metastatic melanoma, this disease remains fatal in the majority of those who develop a relapse. Here, we report the preclinical and early clinical development of a novel IgM antibody PAT-SM6 that specifically binds to a cancer-specific isoform of glucose-regulated protein 78 (GRP78) and low-density lipoprotein. Finding a GRP78 cancer-specific form on the surface of cancer cells, but not normal cells in vivo, presents an opportunity for cancer-specific targeting. PAT-SM6 binding to the cell surface induces apoptosis in a variety of tumors, including melanoma. Recent studies show the specificity of PAT-SM6 binding to the surface of melanoma cells and primary tissue but not to normal tissue. They also confirm, for the first time, cell proliferation inhibition and apoptosis through classical apoptotic pathways as well as induction of lipid accumulation in melanoma cells. These in-vitro data are supported by positive in-vivo data using PAT-SM6 in a xenograft C8161 model. Furthermore, PAT-SM6 was well tolerated in pharmacokinetic/toxicology studies in monkeys. On the basis of these preclinical observations, a clinical study of PAT-SM6 was carried out in patients with 'in-transit' melanoma. Even with microdosing, histological analyses of tumor biopsies detected the presence of PAT-SM6 as well as apoptosis. Although there are many small molecules and monoclonal antibodies currently in clinical development for patients with melanoma, PAT-SM6 is the only therapeutic targeting the cancer-specific isoform of GRP78. These PAT-SM6 preclinical data and positive findings from the phase 1 safety study provide strong support for the further development of this novel antibody. © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins.

This study documents the presence of stable complexes between monoclonal IgM and genomic DNA in freshly harvested mammalian cell culture supernatants. 75% of the complex population elutes from size exclusion chromatography with the same retention volume as IgM. DNA comprises 24% of the complex mass, corresponding to an average of 347 base pairs per IgM molecule, distributed among fragments smaller than about 115 base pairs. Electrostatic interactions appear to provide most of the binding energy, with secondary stabilization by hydrogen bonding and metal affinity. DNA-dominant complexes are unretained by bioaffinity chromatography, while IgM-dominant complexes are retained and coelute with IgM. DNA-dominant complexes are repelled from cation exchangers, while IgM-dominant complexes are retained and partially dissociated. Partially dissociated forms elute in order of decreasing DNA content. The same pattern is observed with hydrophobic interaction chromatography. All complex compositions bind to anion exchangers and elute in order of increasing DNA content. A porous particle anion exchanger was unable to dissociate DNA from IgM. Monolithic anion exchangers, offering up to15-fold higher charge density, achieved nearly complete complex dissociation. The charge-dense monolith surface appears to outcompete IgM for the DNA. Monoliths also exhibit more than double the IgM dynamic binding capacity of the porous particle anion exchanger, apparently due to better surface accessibility and more efficient mass transfer. © 2011 Elsevier B.V.

In contrast to other haematological malignancies, targeted immunotherapy has not entered standard treatment regimens for de novo or relapsed multiple myeloma (MM) yet. While a number of IgG-formatted monoclonal antibodies are currently being evaluated in clinical trials in MM, our study aimed to investigate whether the fully human IgM monoclonal antibody PAT-SM6 that targets a tumour-specific variant of the heat shock protein GRP78 might be an attractive candidate for future immunotherapeutic approaches. We here show that GRP78 is stably and consistently expressed on the surface on tumour cells from patients with de novo, but also relapsed MM and that binding of PAT-SM6 to MM cells can specifically exert cytotoxic effects on malignant plasma cells, whereas non-malignant cells are not targeted. We demonstrate that the induction of apoptosis and, to a lesser extent, complement dependent cytotoxicity is the main mode of action of PAT-SM6, whereas antibody dependent cellular cytotoxicity does not appear to contribute to the cytotoxic properties of this antibody. Given the favourable safety profile of PAT-SM6 in monkeys, but also in a recent phase I trial in patients with malignant melanoma, our results form the basis for a planned phase I study in patients with relapsed MM. © 2013 Rasche et al.
