    Abstract: Purpose: Immunotherapeutic agents produce antitumor effects by inducing cancer-specific immune responses or by modifying native immune processes. Resulting clinical response patterns extend beyond those of cytotoxic agents and can manifest after an initial increase in tumor burden or the appearance of new lesions (progressive disease). Response Evaluation Criteria in Solid Tumors or WHO criteria, designed to detect early effects of cytotoxic agents, may not provide a complete assessment of immunotherapeutic agents. Novel criteria for the evaluation of antitumor responses with immunotherapeutic agents are required. Experimental Design: The phase II clinical trial program with ipilimumab, an antibody that blocks CTL antigen-4, represents the most comprehensive data set available to date for an immunotherapeutic agent. Novel immune therapy response criteria proposed, based on the shared experience from community workshops and several investigators, were evaluated using data from ipilimumab phase II clinical trials in patients with advanced melanoma. Results: Ipilimumab monotherapy resulted in four distinct response patterns: (a) shrinkage in baseline lesions, without new lesions; (b) durable stable disease (in some patients followed by a slow, steady decline in total tumor burden); (c) response after an increase in total tumor burden; and (d) response in the presence of new lesions. All patterns were associated with favorable survival. Conclusion: Systematic criteria, designated immune-related response criteria, were defined in an attempt to capture additional response patterns observed with immune therapy in advanced melanoma beyond those described by Response Evaluation Criteria in Solid Tumors or WHO criteria. Further prospective evaluations of the immune-related response criteria, particularly their association with overall survival, are warranted. (Clin Cancer Res 2009;15(23):7412–20)

    Proteomic Characterization of the Angiogenesis Inhibitor SU6668 Reveals Multiple Impacts on Cellular Kinase Signaling

    Abstract: Knowledge about molecular drug action is critical for the development of protein kinase inhibitors for cancer therapy. Here, we establish a chemical proteomic approach to profile the anticancer drug SU6668, which was originally designed as a selective inhibitor of receptor tyrosine kinases involved in tumor vascularization. By employing immobilized SU6668 for the affinity capture of cellular drug targets in combination with mass spectrometry, we identified previously unknown targets of SU6668 including Aurora kinases and TANK-binding kinase 1. Importantly, a cell cycle block induced by SU6668 could be attributed to inhibition of Aurora kinase activity. Moreover, SU6668 potently suppressed antiviral and inflammatory responses by interfering with TANK-binding kinase 1–mediated signal transmission. These results show the potential of chemical proteomics to provide rationales for the development of potent kinase inhibitors, which combine rather unexpected biological modes of action by simultaneously targeting defined sets of both serine/threonine and tyrosine kinases involved in cancer progression.

    The Coamplification Pattern of the MYCN Amplicon Is an Invariable Attribute of Most MYCN -Amplified Human Neuroblastomas
    American Association for Cancer Research (AACR) ; 2006

    Abstract: Purpose: Fifteen percent to 20% of human neuroblastomas show amplification of the MYCN oncogene physiologically located at chromosome 2p24-25, indicating an aggressive subtype of human neuroblastoma with a poor clinical outcome. Recent findings revealed that the structure of the amplicon differs interindividually and that coamplification of genes in telomeric proximity to MYCN might play a relevant role in neuroblastoma development and response to treatment, respectively. We now asked if the amplicon structure is an invariable attribute of an individual tumor or if the coamplification pattern could change during progress or in case of recurrent disease. Experimental Design: We used a previously described multiplex PCR approach to analyze the coamplification status of MYCN-amplified human neuroblastomas (n = 33) in tumor tissue at the time of initial diagnosis and in consecutive tissue specimens at later time points after initial treatment or from relapsing disease. The MYCN copy number per haploid genome (Mcn/hg) in these specimens was determined in a separate duplex PCR. Results: In 32 of the 33 investigated tumors, the amplicon structure showed no changes after initial chemotherapy and in recurrent disease. Mcn/hg showed a decrease after initial treatment (n = 23), whereas we found a significant increase in recurrent disease (n = 10). Conclusion: Our data indicate that the initial determined structure of the 2p24-25 amplicon is a consistent attribute in the great majority of the individual MYCN-amplified neuroblastomas and shows no plasticity during or after chemotherapy. Observed changes in the Mcn/hg over the course of disease are in line with preexisting cell culture findings.
