Abstract
Immune checkpoint blockade has demonstrated the ability to modulate the immune system to produce durable responses in a wide range of cancers and has significantly impacted the standard of care. However, many cancer patients still do not respond to immune checkpoint blockade or have a limited duration of antitumor responses. Moreover, immune-related adverse events caused by immune checkpoint blockade can be severe and debilitating for some patients, limiting continuation of therapy and resulting in severe autoimmune conditions. Standard-of-care conventional anatomic imaging modalities and tumor response criteria have limitations to adequately assess tumor responses, especially early in the course of therapy, for risk-adapted clinical management to inform care of patients treated with immunotherapy. Molecular imaging with position emission tomography (PET) provides a noninvasive functional biomarker of tumor response, and of immune activation, for patients on immune-based therapies to help address these needs. 18F-FDG (FDG) PET/CT is readily available clinically and a number of studies have evaluated the use of this agent for assessment of prognosis, treatment response and immune activation for patients treated with immune checkpoint blockade. In this review paper, we discuss the current oncologic applications and imaging needs of cancer immunotherapy, recent studies applying FDG PET/CT for tumor response assessment, and evaluation of immune-related adverse events for improving clinical management. We largely focus on metastatic melanoma; however, we generalize where applicable to immunotherapy in other tumor types. We also briefly discuss PET imaging and quantitation as well as emerging non-FDG PET imaging radiotracers for cancer immunotherapy imaging.

Pilot trial of the hu14.18-IL2 immunocytokine in patients with completely resectable recurrent stage III or stage IV melanoma. Cancer Immunol Immunother 2018; 67:1647-1658.

Abstract
Phase I testing of the hu14.18-IL2 immunocytokine (IC) in melanoma patients showed immune activation, reversible toxicities, and a maximal tolerated dose of 7.5 mg/m2/day. Preclinical data in IC-treated tumor-bearing mice with low tumor burden documented striking antitumor effects. Patients with completely resectable recurrent stage III or stage IV melanoma were scheduled to receive 3 courses of IC at 6 mg/m2/day i.v. on days 1, 2 and 3 of each 28-day course. Patients were randomized to complete surgical resection either following neoadjuvant (Group A) or prior to adjuvant (Group B) IC course 1. Primary objectives were to: (1) evaluate histological evidence of anti-tumor activity and (2) evaluate recurrence-free survival (RFS) and OS. Twenty melanoma patients were randomized to Group A (11 patients) or B (9 patients). Two Group B patients did not receive IC due to persistent disease following surgery. Six of 18 IC-treated patients remained free of recurrence, with a median RFS of 5.7 months (95% confidence interval (CI) 1.8-not reached). The 24-month RFS rate was 38.9% (95% CI 17.5-60.0%). The median follow-up of surviving patients was 50.0 months (range: 31.8-70.4). The 24-month OS rate was 65.0% (95% CI 40.3-81.5%). Toxicities were similar to those previously reported. Exploratory tumor-infiltrating lymphocyte (TIL) analyses suggest prognostic value of TILs from Group A patients. Prolonged tumor-free survival was seen in some melanoma patients at high risk for recurrence who were treated with IC.

Abstract
The membrane-associated matrix metalloproteinase-14, MT1-MMP, has been implicated in pericellular proteolysis with an important role in cellular invasion of collagenous tissues. It is substantially upregulated in various cancers and rheumatoid arthritis, and has been considered as a potential therapeutic target. Here, we report the identification of antibody fragments to MT1-MMP that potently and specifically inhibit its cell surface functions. Lead antibody clones displayed inhibitory activity towards pro-MMP-2 activation, collagen-film degradation and gelatin-film degradation, and were shown to bind to the MT1-MMP catalytic domain outside the active site cleft, inhibiting binding to triple helical collagen. Affinity maturation using CDR3 randomization created a second generation of antibody fragments with dissociation constants down to 0.11 nM, corresponding to an improved affinity of 332-fold with the ability to interfere with cell-surface MT1-MMP functions, displaying IC50 values down to 5 nM. Importantly, the new inhibitors were able to inhibit collagen invasion by tumor-cells in vitro and in vivo primary tumor growth and metastasis of MDA-MB-231 cells in a mouse orthotopic xenograft model. Herein is the first demonstration that an inhibitory antibody targeting sites outside the catalytic cleft of MT1-MMP can effectively abrogate its in vivo activity during tumorigenesis and metastasis.

Abstract
Immunotoxins are antibody-toxin fusion proteins under development as cancer therapeutics. In early clinical trials, immunotoxins constructed with domains II and III of Pseudomonas exotoxin (termed PE38), have produced a high rate of complete remissions in Hairy Cell Leukemia and objective responses in other malignancies. Cholera exotoxin (also known as cholix toxin) has a very similar three-dimensional structure to Pseudomonas exotoxin (PE) and when domains II and III of each are compared at the primary sequence level, they are 36% identical and 50% similar. Here we report on the construction and activity of an immunotoxin made with domains II and III of cholera exotoxin (here termed CET40). In cell viability assays, the CET40 immunotoxin was equipotent to tenfold less active compared to a PE-based immunotoxin made with the same single-chain Fv. A major limitation of toxin-based immunotoxins is the development of neutralizing antibodies to the toxin portion of the immunotoxin. Because of structure and sequence similarities, we evaluated a CET40 immunotoxin for the presence of PE-related epitopes. In western blots, three-of-three anti-PE antibody preparations failed to react with the CET40 immunotoxin. More importantly, in neutralization studies neither these antibodies nor those from patients with neutralizing titers to PE38, neutralized the CET40-immunotoxin. We propose that the use of modular components such as antibody Fvs and toxin domains will allow a greater flexibility in how these agents are designed and deployed including the sequential administration of a second immunotoxin after patients have developed neutralizing antibodies to the first.

Abstract
The identification of proteins that are preferentially expressed on the membrane of metastatic tumor cells is of fundamental importance in cancer research. Here, we report the systematic comparison of the membrane proteome of two closely related murine teratocarcinoma cell lines (F9B9 and F9DR), of which only one (F9DR) is capable of forming liver metastases in vivo. The proteomic methodology used in this study featured the surface protein biotinylation on tumor cells followed by protein purification on streptavidin resin and relative quantification of corresponding tryptic peptides by mass spectrometric procedures. The study allowed the identification of 998 proteins and the determination of their relative abundance. Proteins previously known to be associated with metastatic spread were found to be either up-regulated (e.g., synaptojanin-2) or down-regulated (e.g., Ceacam1) in F9DR cells. A dramatic increase in abundance at the cell membrane was observed for a broad variety of proteins (e.g., high-mobility group protein B1), which were mainly thought to reside in intracellular compartments, a finding that was confirmed using confocal laser scanning microscopy and immunochemical analysis of cell cultures. Furthermore, we showed by microautoradiographic analysis that certain target proteins can readily be reached by intravenously administered radiolabeled antibodies. Finally, we showed that the most promising antigens for antibody-based pharmacodelivery approaches are strongly and selectively expressed on the surface of tumor cells in three different syngeneic mouse models of liver metastases. Taken together, our results indicate that the expression of intracellular proteins on the membrane of metastatic cells is a feature much more common than previously expected.

Abstract
Cetuximab, an anti-epidermal growth factor receptor monoclonal antibody, has been shown to increase the median survival of colorectal cancer patients. We previously reported that the expression of HLA-E is significantly increased in primary human colorectal cancer, perhaps contributing to tumour escape from immune surveillance. To establish if HLA-E could be a factor that renders colorectal cancer cells less susceptible to antibody-dependent cellular cytotoxicity (ADCC), in the present study we analysed Cetuximab-mediated cytotoxicity against several colorectal cancer cell lines expressing, or not, HLA-E at the cell surface. We first observed that colorectal cancer cells treated with Cetuximab were killed more efficiently by ADCC. Interestingly, treatment of target cells with recombinant human-beta2-microglobulin inhibits Cetuximab-mediated ADCC through HLA-E membrane stabilization. The specific immunosuppressive role of HLA-E was confirmed using an anti-NKG2A monoclonal antibody, that restored the ability of immune cells to kill their target. This result demonstrates that HLA-E at the cell surface can reliably suppress the ADCC effect. On the other hand, Cetuximab induced a direct growth inhibition but only at high concentrations; furthermore, the CDC effect was quite moderate, and we failed to observe a pro-apoptotic effect. Taking into account that our findings suggest that ADCC activity is the main anti-tumour effect observed at clinically achievable concentrations of Cetuximab at the tumour site, we suggest that determination of HLA-E in colorectal cancer could be relevant to predict success of Cetuximab treatment.
