Abstract
Introduction Vidutolimod, a CpG-A TLR9 agonist, was investigated in a phase 1b study (CMP-001-003; ClinicalTrials.gov, NCT03438318) in combination with atezolizumab with and without radiation therapy (RT) in patients with advanced NSCLC. Methods Patients with progressive disease after anti-programmed cell death protein 1 or programmed death-ligand 1 therapy received either vidutolimod and atezolizumab (part A) or vidutolimod, atezolizumab, and RT (part B). The primary objective was to evaluate the safety of vidutolimod and atezolizumab with and without RT. Key secondary end point was best objective response rate per Response Evaluation Criteria in Solid Tumors, version 1.1. Results Between March 28, 2018, and July 25, 2019, a total of 29 patients were enrolled and received at least one dose of vidutolimod (part A, n = 13; part B, n = 16). Intratumoral injections of vidutolimod were administered successfully, including injection of visceral lesions. The most common treatment-related adverse events (≥30%) were flu-like symptoms and hypotension. No objective responses were observed; 23.1% and 50.0% of the patients in parts A and B, respectively, had stable disease as best response. In parts A and B, 15.4% and 25.0% of the patients, respectively, had tumor shrinkage (<30% decrease in tumor size, nonirradiated). Enrollment was stopped owing to lack of objective responses. In the two patients with initial tumor shrinkage in part A, a strong serum induction of C-X-C motif chemokine ligand 10 was observed. Conclusions Vidutolimod and atezolizumab with and without RT had a manageable safety profile, with minimal clinical activity in heavily pretreated patients with programmed cell death protein 1 or programmed death-ligand 1 blockade-resistant NSCLC.

Abstract
Abstract
Background: Vidu is a first-in-class CpG-A TLR9 agonist in a virus-like particle that activates plasmacytoid dendritic cells (pDC), thus bridging innate and adaptive immunity. Intratumoral (IT) vidu alone or in combination with intravenous (IV) anti-PD-(L)1 has shown evidence of antitumor activity in pts with anti-PD-(L)1-refractory melanoma or NSCLC. As biomarkers associated with anti-PD-(L)1 response were not predictive of vidu activity, we sought to identify novel transcriptional signatures.
Methods: RNA-Seq was performed on baseline biopsies from pts with anti-PD-(L)1-refractory melanoma (NCT02680184; RECIST v1.1 responders [R; n=20]; nonresponders [NR; n=78; 30 pts with stable disease + 48 pts with progressive disease [PD]]) or NSCLC (NCT03438318; N=11) treated with vidu ± anti-PD-(L)1. IFNg18 signature was used to characterize melanomas as non-T cell-inflamed (non-Tinfl), T cell-inflamed (Tinfl), or intermediate. Gene Set Enrichment Analysis (GSEA) using MSigDB and other signatures (>19,000) was performed on non-Tinfl melanoma in R vs NR (false discovery rate [FDR] <0.25). Deconvolution of immune cells was performed using TIMER2.0. Prediction models were generated using QLattice. Signatures were characterized using both publicly available bulk and single-cell (sc) RNA-Seq datasets of pDC subsets or PD-1/CTLA-4 blockade response datasets.
Results: GSEA on non-Tinfl melanoma biopsies revealed 2 gene signatures (COPII vesicle and Golgi targeting) most strongly associated with R (FDR <0.16). Leading edge analysis of these signatures identified 35 common core genes (CC) that strongly differentiated RECIST 1.1 R vs PD. As independent validation, CC enrichment was also significantly associated with R in intermediate melanoma (p=0.009) and with tumor shrinkage in NSCLC (p=0.027). CC was significantly associated with R to vidu single-agent or combination treatment, but not with clinical baseline prognostic factors or IFNg18. In Tinfl melanoma, CC was not associated with R, but myeloid signatures were significantly associated with NR. A model based on CC and transcription factor ELF2 predicted R in melanoma (AUC 0.93 [95% CI 0.82-1.00]). In public datasets, CC was not associated with R to PD-1/CTLA-4 blockade, but CC was highly expressed in the type I interferon-secreting subset of pDCs and some myeloid cells. CC expression was prevalent in most tumor types and was independent of IFNg18 in TCGA.
Conclusion: In pts with anti-PD-1-refractory melanoma or NSCLC, transcriptional signatures of COPII vesicle and Golgi targeting (functionally related to TLR9 activation) were associated with antitumor activity of IT vidu ± IV anti-PD-(L)1. Ongoing bulk and sc RNA-Seq analyses may clarify the underlying biology and the signature’s potential role as a predictive biomarker for clinical response to vidu.

Abstract
Patients with advanced melanoma that is resistant to programmed death-1 (PD-1) blockade therapy have limited treatment options. Vidutolimod (formerly CMP-001), a virus-like particle containing a CpG-A Toll-like receptor 9 (TLR9) agonist, may reverse PD-1 blockade resistance by triggering a strong interferon response to induce and attract antitumor T cells. In the dose-escalation part of this phase 1b study, vidutolimod was administered intratumorally at escalating doses with intravenous pembrolizumab to 44 patients with advanced melanoma who had progressive disease or stable disease on prior anti-PD-1 therapy. The combination of vidutolimod and pembrolizumab had a manageable safety profile and durable responses were observed in 25% of patients, with tumor regression in both injected and noninjected lesions, including visceral lesions. Patients who responded to vidutolimod and pembrolizumab had noninflamed tumors at baseline and induction of an interferon-γ gene signature following treatment, as well as increased systemic expression of the interferon-inducible chemokine CXCL10.

Abstract
Abstract
Background
In the treatment-naive setting, PD-1 blockade is associated with greater response in T cell-inflamed vs non-T cell-inflamed tumors. CMP-001 is a CpG-A oligonucleotide TLR9 agonist in a virus-like particle that is hypothesized to activate tumor-associated plasmacytoid dendritic cells (pDCs) to secrete type I interferons. Through this activity, CMP-001 may convert the tumor microenvironment to a Th1-like chemokine milieu (eg, increased CXCL10) and induce an antitumor CD8+ T-cell response. We have recently reported that intratumoral injection of CMP-001 + IV pembrolizumab (pembro) had an acceptable safety profile and can reverse PD-1 blockade resistance in patients (pts) with melanoma (Milhem et al, SITC 2019). Regression was observed in injected and uninjected lesions. Herein we report pharmacodynamic and translational data.
Methods
This 2-part, open-label, multicenter, phase 1b study (NCT02680184) enrolled pts with metastatic/unresectable melanoma and stable disease (SD) or progressive disease (PD) on/after anti−PD-1 therapy. In part 1 (3+3 dose-escalation and dose-expansion), pts received CMP-001 + pembro. In part 2, pts received CMP-001 monotherapy. Determination of safety and clinical activity were the study's main objectives. Prespecified pharmacodynamic and translational studies evaluated serum chemokines and evaluated tumor biopsies using RNA and/or whole exome sequencing and immunohistochemistry for PD-L1 (reported as H-score), CD8, and CD303 (pDC marker).
Results
As of September 30, 2020, 159 pts (part 1) and 40 pts (part 2) have been treated. A greater median fold increase of serum CXCL10 (a marker of innate immunity, n=40) was observed in responders (R) to CMP-001 + pembro (18.8x) vs nonresponders (NR) after treatment (9.9x in SD; 6.15x in PD; differences were not statistically significant). Preliminary analyses showed that interferon gene expression distinguished R vs NR. Tumor biopsy analyses (part 1, n=139; part 2, n=34) showed that pts with high PD-L1, high CD8+ T cells, or inflamed transcriptional signatures at baseline were less likely to respond to CMP-001 + pembro vs pts without inflammation markers at baseline. Baseline mean PD-L1 expression (H-score) was 8.1 in R (n=10) vs 21.8 in NR (n=49). Posttreatment biopsies generally showed increased PD-L1, CD8+ T cells, and inflamed transcriptional signatures in R vs NR. Neither tumor mutational burden nor baseline pDC density distinguished R vs NR.
Conclusions
In pts with anti-PD-1 refractory melanoma, intratumoral CMP-001 ± pembro appears to disproportionately induce antitumor responses in noninflamed tumors. Clinical response to CMP-001 ± pembro was associated with induction of markers of both innate and adaptive antitumor immunity.

Abstract
Metabolic dysregulation is a hallmark of cancer. Many tumors exhibit auxotrophy for various amino acids, such as arginine, because they are unable to meet the demand for these amino acids through endogenous production. This vulnerability can be exploited by employing therapeutic strategies that deplete systemic arginine in order to limit the growth and survival of arginine auxotrophic tumors. Pegzilarginase, a human arginase-1 enzyme engineered to have superior stability and enzymatic activity relative to the native human arginase-1 enzyme, depletes systemic arginine by converting it to ornithine and urea. Therapeutic administration of pegzilarginase in the setting of arginine auxotrophic tumors exerts direct antitumor activity by starving the tumor of exogenous arginine. We hypothesized that in addition to this direct effect, pegzilarginase treatment indirectly augments antitumor immunity through increased antigen presentation, thus making pegzilarginase a prime candidate for combination therapy with immuno-oncology (I-O) agents. Tumor-bearing mice (CT26, MC38, and MCA-205) receiving pegzilarginase in combination with anti-PD-L1 or agonist anti-OX40 experienced significantly increased survival relative to animals receiving I-O monotherapy. Combination pegzilarginase/immunotherapy induced robust antitumor immunity characterized by increased intratumoral effector CD8+ T cells and M1 polarization of tumor-associated macrophages. Our data suggest potential mechanisms of synergy between pegzilarginase and I-O agents that include increased intratumoral MHC expression on both antigen-presenting cells and tumor cells, and increased presence of M1-like antitumor macrophages. These data support the clinical evaluation of I-O agents in conjunction with pegzilarginase for the treatment of patients with cancer.

Abstract
In this double-blind, Phase 2 study, 220 patients with relapsed/refractory multiple myeloma were randomly assigned 1:1:1 to receive placebo (N = 72), tabalumab 100 mg (N = 74), or tabalumab 300 mg (N = 74), each in combination with dexamethasone 20 mg and subcutaneous bortezomib 1·3 mg/m2 on a 21-day cycle. No significant intergroup differences were observed among primary (median progression-free survival [mPFS]) or secondary efficacy outcomes. The mPFS was 6·6, 7·5 and 7·6 months for the tabalumab 100, 300 mg and placebo groups, respectively (tabalumab 100 mg vs. placebo Hazard ratio (HR) [95% confidence interval (CI)] = 1·13 [0·80-1·59], P = 0·480; tabalumab 300 mg vs. placebo HR [95% CI] = 1·03 [0·72-1·45], P = 0·884). The most commonly-reported treatment-emergent adverse events were thrombocytopenia (37%), fatigue (37%), diarrhoea (35%) and constipation (32%). Across treatments, patients with low baseline BAFF (also termed TNFSF13B) expression (n = 162) had significantly longer mPFS than those with high BAFF expression (n = 55), using the 75th percentile cut-off point (mPFS [95% CI] = 8·3 [7·0-9·3] months vs. 5·8 [3·7-6·6] months; HR [95% CI] = 1·59 [1·11-2·29], P = 0·015). Although generally well tolerated, PFS was not improved during treatment with tabalumab compared to placebo. A higher dose of 300 mg tabalumab did not improve efficacy compared to the 100 mg dose. Nonetheless, BAFF appears to have some prognostic value in patients with multiple myeloma.

Abstract
Purpose: The MET/HGF pathway regulates cell proliferation and survival and is dysregulated in multiple tumors. Emibetuzumab (LY2875358) is a bivalent antibody that inhibits HGF-dependent and HGF-independent MET signaling. Here, we report dose escalation results from the first-in-human phase I trial of emibetuzumab.Experimental Design: The study comprised a 3+3 dose escalation for emibetuzumab monotherapy (Part A) and in combination with erlotinib (Part A2). Emibetuzumab was administered i.v. every 2 weeks (Q2W) using a flat dosing scheme. The primary objective was to determine a recommended phase II dose (RPTD) range; secondary endpoints included tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and antitumor activity.Results: Twenty-three patients with solid tumors received emibetuzumab monotherapy at 20, 70, 210, 700, 1,400, and 2,000 mg and 14 non-small cell lung cancer (NSCLC) patients at 700, 1,400, and 2,000 mg in combination with erlotinib 150 mg daily. No dose-limiting toxicities and related serious or ≥ grade 3 adverse events were observed. The most common emibetuzumab-related adverse events included mild diarrhea, nausea, and vomiting, and mild to moderate fatigue, anorexia, and hypocalcemia in combination with erlotinib. Emibetuzumab showed linear PK at doses >210 mg. Three durable partial responses were observed, one for emibetuzumab (700 mg) and two for emibetuzumab + erlotinib (700 mg and 2,000 mg). Both of the responders to emibetuzumab + erlotinib had progressed to prior erlotinib and were positive for MET protein tumor expression.Conclusions: Based on tolerability, PK/PD analysis, and preliminary clinical activity, the RPTD range for emibetuzumab single agent and in combination with erlotinib is 700 to 2,000 mg i.v. Q2W. Clin Cancer Res; 23(8); 1910-9. ©2016 AACR.

Here we report on a phase I study of relapsed/refractory multiple myeloma patients in which the primary objective was to identify a tolerable and potentially efficacious dose of tabalumab when combined with bortezomib. EXPERIMENTAL DESIGN Forty-eight patients were enrolled; 20 to the dose-escalation cohort, and 28 to cohort expansion in which a dose of 100 mg of tabalumab was evaluated. All patients had received either prior bortezomib or an immunomodulatory drug; the median number of prior therapies was 3. Bortezomib was administered intravenously on days 1, 4, 8, and 11 of a 21-day schedule. Tabalumab was given every 21 days for 3 cycles, then every 42 days thereafter. RESULTS The most common grade 3/4 toxicities included thrombocytopenia, neutropenia, pneumonia, and peripheral sensory neuropathy. There were no dose-limiting toxicities, and the maximum tolerated dose was not reached. Pharmacokinetic data suggested serum exposure increased in a greater than dose-proportional manner up to a dose of 100 mg. Out of 46 evaluable patients, 20 had confirmed responses. The median time to progression (9 patients censored) was 4.8 months, and the median response duration (4 patients censored) was 7.2 months. CONCLUSIONS A dose of 100 mg tabalumab in combination with bortezomib was well tolerated and active and is currently under further investigation. Clin Cancer Res; 22(23); 5688-95. ©2016 AACR.

Abstract
OBJECTIVE A potential complication for all new multiple myeloma (MM) patients is the clinical presentation of osteolytic lesions which increase the risk for skeletal-related events (SREs). However, the contribution of SREs to the overall economic impact of MM is unclear. The impact of SREs on healthcare resource utilization (HCRU) and costs for US patients with MM was analyzed in Truven Health Marketscan Commercial Claims and Medicare Supplemental Databases. METHODS Adults diagnosed with MM between January 1, 2005 and December 31, 2010 with ≥2 claims ≥30 days apart (first claim = index date) were included. SREs included: hypercalcemia, pathologic fracture, surgery for the prevention and treatment of pathologic fractures or spinal cord compression, and radiation for bone pain. Rates of HCRU (outpatient [OP], inpatient [IP], emergency room [ER], orthopedic consultation [OC], and ancillary) and healthcare costs were compared between MM patients with and without SREs. Inverse propensity weighting was applied to adjust for potential bias. RESULTS Of 1028 MM patients (mean age = 67, standard deviation = 13.2), 596 patients with ≥1 SRE and 432 without SREs were assessed. HCRU rates in IP, ER, and ancillary (p < 0.01) and mean total costs of OP, IP, and ER were significantly higher (p < 0.05) for patients with vs without SREs during follow-up. HCRU rates also increased with SRE frequency (p < 0.05 in OP, IP, ER, OC, and ancillary), as did mean total healthcare costs, except for OC (p < 0.001). LIMITATIONS A broad assessment of pharmacotherapy for the treatment of MM was not an objective of the current study. Bisphosphonate use was evaluated; however, results were descriptively focused on frequency of utilization only and were not included in the broader cost and HCRU analysis. CONCLUSIONS Among US patients with MM, higher SRE frequency was associated with a significant trend of higher HCRU and total healthcare costs in several settings.

Abstract
This phase 2 study assessed the safety and efficacy of ocaratuzumab, a humanized anti-CD20 monoclonal antibody. Fifty patients with previously treated follicular lymphoma (FL) and a low-affinity genotype of FcγRIIIa received ocaratuzumab 375 mg/m(2) weekly for 4 weeks. Grade 3/4/5 adverse events (AEs) were reported in 11/1/1 patients, respectively. Serious AEs were reported by 11/50 patients, and three discontinued due to AEs. One patient died from aspiration pneumonia due to possibly drug-related nausea and vomiting. Investigator-assessed response rate was 30% (15/50), including four complete responses (CR), three CR unconfirmed (CRu) and eight partial responses (PR). Investigator-assessed median Progression-free survivial (PFS) was 38.3 weeks. Ocaratuzumab's pharmacokinetic profile was similar to that reported for rituximab. Lymphocyte subset analysis showed significant, selective reduction of B-cells during and after ocaratuzumab treatment. Ocaratuzumab at this dose and schedule is active and well tolerated in patients with previously treated FL with low affinity FcγRIIIa genotypes. ClinTrials registry number: NCT00354926.

Abstract
Enzastaurin is an oral serine/threonine kinase inhibitor of the protein kinase C (PKC) and phosphatidylinositol 3 (PI3) kinase/Akt pathways that induces apoptosis in multiple myeloma (MM) cell lines in a caspase-independent manner. A phase II study was conducted to assess response rate, time to progression (TTP), safety and biomarker association with clinical outcomes after monotherapy with the PKC inhibitor enzastaurin in previously treated patients with MM. Eligible patients (n = 14) were treated with enzastaurin 250 mg twice daily after receiving loading doses on day 1. One minimal response was observed. The median TTP was 5.11 months. There were two grade 3 adverse events, anemia and prolonged QTc interval, and no grade 4 adverse events. Single-agent enzastaurin was well tolerated but not effective in this heavily pretreated population with MM.

Abstract
8093 Background: Activation of the hepatocyte growth factor (HGF)/MET receptor pathway promotes tumor growth, invasion and dissemination. LY is a humanized IgG4 monoclonal bivalent antibody against MET which inhibits ligand dependent- and ligand independent activation of MET. Based on preclinical results, we examined LY alone in patients with advanced solid tumors and LY+E in advanced NSCLC patients. Methods: LY monotherapy was administered 20-2,000 mg Q2W IV to 23 patients with advanced solid tumors. Combination therapy with 700-2,000 mg Q2W IV of LY and E (150 mg QD) was completed in 14 patients with advanced NSCLC. The primary objective was to determine a recommended phase II dose (RPTD) for LY and LY+E. Secondary objectives included assessment of toxicity, PK, PD (including MET extracelluar domain and HGF), and antitumor activity. Results: LY and LY+E were well tolerated. No dose-limiting toxicities, serious adverse events, or ≥ Grade 3 adverse events (AEs) possibly related to LY have been observed. The most frequent (≥5% of patients) AEs possibly related to LY2875358 monotherapy were nausea (8.7 %), vomiting (8.7%), and diarrhea (8.7%). The most frequent (≥10% of patient) grade 1 or 2 adverse event possibly related to LY2875358 in patients treated with LY+E were fatigue (21.4%) and anorexia (14.3%). Durable PR according to RECIST were observed for LY (n=1) and LY+E (n=2 out of 13 evaluable patients; both PR patients positive for MET protein expression). Conclusions: LY appears to be safe when administered as single agent and in combination with E up to 2,000 mg Q2W IV. The RPTD of LY is 750 mg Q2W IV for monotherapy and in combination with E based on PK/PD data. Clinical trial information: NTC 01287546.

Abstract
PURPOSE Enzastaurin is a serine/threonine kinase inhibitor that showed antiangiogenic, antiproliferative, and proapoptotic properties in vitro and antitumor activity in vivo in a xenograft Waldenström macroglobulinemia (WM) model. These findings provided the rationale for a multicenter phase II trial of oral enzastaurin in previously treated patients with WM. EXPERIMENTAL DESIGN Patients who were treated with 1 to 5 prior regimens and who had a baseline immunoglobulin M level 2 times or more the upper limit of normal received oral enzastaurin 250 mg twice daily (500 mg total) after a single loading dose (day 1, cycle 1) of 375 mg 3 times daily (1,125 mg total) for 8 cycles of 28 days each or until progressive disease. Six patients who progressed during treatment with enzastaurin had dexamethasone added per protocol. RESULTS From July 2008 to December 2010, 42 patients were enrolled. The objective response rate (RR) was 38.1% (2 partial and 14 minor responses). One patient had grade 3 leukopenia and one patient died during the study from septic shock; both events were considered drug related. A statistically significant association between RR and interleukin 15 (IL-15) was observed, suggesting that higher concentration levels of IL-15 may be associated with better response. CONCLUSION Enzastaurin was active and well tolerated in previously treated patients with WM. Because of the small sample size of this uncontrolled study, further assessment of the relationship between IL-15 and response to enzastaurin in patients with WM is required. These results warrant further investigation of enzastaurin for the treatment of WM.

Abstract
AIMS B-cell chronic lymphocytic leukemia (CLL) is a heterogeneous malignancy that clinically ranges from indolent to rapidly progressive. CLL, like other cancers, can be affected by epigenetic alterations. MATERIALS & METHODS A microarray discovery-based study was initiated to determine DNA methylation in CLL cases with a range of CD38 expression (1–92%). RESULTS Many loci were either methylated or unmethylated across all CD38 levels, but differential methylation was also observed for some genes. Genomic sequencing of DLEU7 confirmed extensive cytosine methylation preferentially in patient samples with low CD38 expression, whereas NRP2, SFRP2 and ADAM12 were more commonly methylated in those with high CD38 expression. CONCLUSION This study demonstrates that CLL is affected by CpG island methylation in some genes that segregate with CD38 expression levels, while most others show similar methylation patterns across all levels. The CpG island methylation in certain functional gene groups and pathway-associated genes that are known to be deregulated in CLL provides additional insights into the CLL methylome and epigenetic contribution to cellular dysfunction. It will now be useful to investigate the effectiveness of epigenetic therapeutic reversal of these alterations to develop effective treatments for the disease.

Abstract
PURPOSE AME-133v is a humanized monoclonal antibody engineered to have increased affinity to CD20 and mediate antibody-dependent cell-mediated cytotoxicity (ADCC) better than rituximab. Safety, pharmacokinetics, and efficacy were assessed in a phase 1/2 trial in patients with previously treated follicular lymphoma (FL). PATIENTS AND METHODS AME-133v was characterized in vitro by ADCC and cell binding assays. A phase 1 study was conducted in which 23 previously treated patients with FL were assigned sequentially to one of five dose-escalation cohorts of AME-133v at 2, 7.5, 30, 100, or 375 mg/m(2) weekly × 4 doses. RESULTS AME-133v showed a 13- to 20-fold greater binding affinity for CD20 and was 5- to 7-fold more potent than rituximab in ADCC assays. Cell binding assays showed AME-133v and rituximab competed for an overlapping epitope on the CD20 antigen, and AME-133v inhibited binding of biotinylated rituximab to CD20 in a concentration-dependent manner. AME-133v was well tolerated by patients and common related adverse events included chills and fatigue. One patient experienced a dose-limiting toxicity of neutropenia. AME-133v showed nonlinear pharmocokinetics with properties similar to rituximab. Selective reduction of B cells during and after AME-133v treatment was shown by flow cytometry of peripheral blood. A partial or complete response was observed in 5 of 23 (22%) patients and the median progression-free survival was 25.4 weeks. CONCLUSIONS AME-133v was safe and well tolerated at the doses tested. AME-133v showed encouraging results as an anti-CD20 therapy in heavily pretreated FL patients with the less favorable FcγRIIIa F-carrier genotype.

Abstract
CpG oligonucleotide 7909 (CpG 7909, PF-03512676), a synthetic 24mer single stranded agonist of TLR9 expressed by B cells and plasmacytoid dendritic cells, is immunomodulatory and can cause activation-induced death of chronic lymphocytic leukemia (CLL) cells. We report a phase I study of CpG 7909 in 41 patients with early relapsed CLL. A single intravenous dose of CpG 7909 was well tolerated with no clinical effects and no significant toxicity up to 1.05 mg/kg. Single dose subcutaneous CpG 7909 had a maximum tolerated dose (MTD) of 0.45 mg/kg with dose limiting toxicity of myalgia and constitutional effects. Multiple weekly subcutaneous doses at the MTD were well tolerated. CpG 7909 administration induced immunologic changes in CLL and non-malignant cells that were dose and route dependent. We conclude that multidose therapy with subcutaneous CpG 7909 (0.45 mg/kg) could be used in future phase II combination clinical trials for CLL.

Abstract
The purpose of this study was to assess the safety and identify the recommended doses of enzastaurin and bortezomib in combination for future Phase II studies in patients with relapsed or refractory multiple myeloma. Three dose levels (DLs) of oral enzastaurin and intravenous bortezomib were used according to a conventional "3 + 3" design. A loading dose of enzastaurin (250 mg twice/day [BID]) on Day 1 was followed by enzastaurin 125 mg BID for 1 week, after which bortezomib was added (Cycle 1, 28 days, 1.0 mg/m(2) : Days 8, 11, 15, and 18; seven subsequent 21-day cycles, 1.3 mg/m(2) : Days 1, 4, 8, and 11). Twenty-three patients received treatment; all patients received prior systemic therapy. Most patients received ≥3 regimens; 17 patients were bortezomib-refractory. A median of four treatment cycles (range 1-24) was completed. No dose-limiting toxicities were observed; thus, DL 3 was the recommended Phase II dose. The most common drug-related Grade 3/4 toxicities were thrombocytopenia (n = 6) and anemia (n = 2). No patients died on therapy. One patient (DL 1) achieved a very good partial response; three patients (DLs 2 and 3), a partial response; nine patients, stable disease; and four patients, progressive disease. The recommended Phase II doses in patients with relapsed or refractory multiple myeloma are as follows: enzastaurin loading dose of 375 mg three times/day on Day 1 followed by 250 mg BID, with bortezomib 1.3 mg/m(2) on Days 1, 4, 8, and 11 of a 21-day cycle. The combination was well-tolerated and demonstrated some antimyeloma activity.

Abstract
Granulocyte-macrophage colony stimulating factor (GM-CSF) has been shown to enhance CD20 antigen expression, augment antibody-dependent cell-mediated cytotoxicity, and stimulate immune cell proliferation. This may lead to an improved anti-tumor effect of rituximab while reducing the severity of chemotherapy-induced myelosuppression. We evaluated the safety and efficacy of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in sequential combination with GM-CSF priming and rituximab in previously untreated patients (n = 39) with diffuse-large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL). CHOP was administered every 21 days on day 1, GM-CSF 250 μg/m(2)/day on days 9 through 15, and rituximab 375 mg/m(2) on day 15 of each cycle. The overall response rate was 87%, with complete response in 64%. At a median follow-up of 84.3 months, the overall and progression-free survival rates were 54% and 49%, respectively. The most common toxicity was myelosuppression. Sequential combination of CHOP with GM-CSF priming and rituximab was feasible and effective, warranting further evaluation.

Abstract
Patients with follicular lymphoma (FL), where position 158 of FcγR-IIIa is heterozygous valine/phenylalanine or homozygous phenylalanine (F-carriers), have natural killer cells with lower binding affinity to IgG than valine homozygote patients. In addition, F-carriers show less efficacy with rituximab treatment than patients homozygous for valine. LY2469298 is a humanized IgG1 monoclonal antibody targeting CD20, with human germline framework regions, and specific amino acid substitutions engineered into the Fc region to increase effector function in antibody-dependent cell-mediated cytotoxicity. This dose-escalation, phase I study was conducted to assess the safety, pharmacokinetics and preliminary efficacy of LY2469298 in Japanese patients with previously treated, CD20-positive FL who had not relapsed or progressed within 120 days of prior rituximab. LY2469298 was administered by intravenous infusion at 100 or 375 mg/m(2) weekly for 4 weeks. Ten patients were enrolled (median age, 60 years); all had previously been treated with rituximab. Nine patients were F-carriers while one was homozygous for valine at position 158 of FcγRIIIa. No patients developed dose-limiting toxicities, and the most frequent adverse events were lymphopenia, pyrexia, leukopenia, chills and neutropenia. Five (50%) of the ten patients responded to LY2469298 treatment (three complete responses, one unconfirmed complete response and one partial response). Serum LY2469298 was eliminated in a biphasic manner and the pharmacokinetic profiles were not different from those in a preceding study in the United States. In conclusion, LY2469298 was well tolerated and clinical activity was observed in FL patients pretreated with rituximab, mostly consisting of F-carriers. Further investigation of FL is warranted.

Abstract
PURPOSE To report a case of anaplastic large cell lymphoma (ALCL) of the central nervous system (CNS) producing an optic neuropathy. METHODS Observational case report. RESULTS A 29-year-old male presented with new onset headaches. Magnetic resonance imaging (MRI) of the brain revealed a large enhancing parietal lobe mass. Ocular exam at that time was normal. Initial diagnoses included possible bacterial cerebritis and fungal abscess. Serial lumbar punctures showed increased white blood cells but cytology was negative. A brain biopsy was non-diagnostic. The patient then presented with a left optic neuropathy. Repeat MRI of the brain and orbits revealed infiltration of the clivus and left orbital apex including the optic nerve. The patient had elevated liver function studies and an abdominal ultrasound disclosed two hypoechoic lesions. Liver biopsy confirmed the diagnosis of ALK-1 positive ALCL. The patient was treated with chemotherapy but expired seven months after the initial presentation. CONCLUSION ALCL should be considered to be a very rare but potential cause of optic neuropathy. To our knowledge, this is the first reported case of ALCL causing an optic neuropathy.

Abstract
When uncomplicated neutropenia during doxorubicin (Adriamycin), bleomycin, vinblastine and dacarbazine (ABVD) chemotherapy for the treatment of Hodgkin's lymphoma is encountered, it is unclear whether or not treatment should be modified. In the present study, we determined the incidence of neutropenia, febrile neutropenia, and the relationship of febrile neutropenia to grade III/IV neutropenia and dose modification, in a large university patient population. We reviewed the charts of patients diagnosed with Hodgkin's lymphoma between 1 January 1990 and 31 December 2002 who were treated with ABVD chemotherapy, and seen at the University of Iowa with complete diagnosis, staging, and treatment dosing records. Adequate data was available on 894 treatments in 81 patients with Hodgkin's lymphoma treated with ABVD chemotherapy. Grade III/IV neutropenia was present on the scheduled day of treatment in 187 (20.9%) treatments in 64 (79%) patients. Grade III/IV neutropenia was most common at cycle 1 day 15. Febrile neutropenia developed nine times in eight patients, and eight episodes of febrile neutropenia developed when the treatment-day absolute neutrophil count (ANC) > or =1000. Dose delay of >4 days and/or dose reduction to <80% of original doxorubicin dose following grade III/IV neutropenia occurred in 29 of 187 treatments, with no episodes of febrile neutropenia. With grade III/IV neutropenia on the day of therapy, 158 treatments were administered without dose reduction or dose delay with one subsequent episode of febrile neutropenia. Neutropenia during ABVD is common, and dose modification for uncomplicated neutropenia on the day of treatment may not reduce the risk of febrile neutropenia. It may be possible to maintain dose intensity in the face of uncomplicated neutropenia during ABVD therapy.

Abstract
Oligodeoxynucleotides containing CpG motifs (CpG ODN) can alter various immune cell subsets important in antibody therapy of malignancy. We undertook a phase I trial of CPG 7909 (also known as PF-3512676) in patients with previously treated lymphoma with the primary objective of evaluating safety across a range of doses, and secondary objectives of evaluating immunomodulatory effects and clinical effects. Twenty-three patients with previously treated non-Hodgkin lymphoma received up to 3 weekly 2-hour intravenous (IV) infusions of CPG ODN 7909 at dose levels 0.01 to 0.64 mg/kg. Evaluation of immunologic parameters and clinical endpoints occurred for 6 weeks. Infusion-related toxicity included grade 1 nausea, hypotension, and IV catheter discomfort. Serious adverse hematologic events observed more than once included anemia (2=Gr3, 2=Gr4), thrombocytopenia (4=Gr3), and neutropenia (2=Gr3), and were largely judged owing to progressive disease. Immunologic observations included: (1) The mean ratio of NK-cell concentrations compared with pretreatment at day 2 was 1.44 (95% CI=0.94-1.94) and at day 42 was 1.53 (95% CI=1.14-1.91); (2) NK activity generally increased in subjects; and (3) Antibody-dependent cellular cytotoxicity activity increased in select cohorts. No clinical responses were documented radiographically at day 42. Two subjects demonstrated late response. We conclude CpG 7909 can be safely given as a 2-hour IV infusion to patients with previously treated non-Hodgkin lymphoma at doses that have immunomodulatory effects.

Abstract
Growing evidence indicates that the affinity of monoclonal antibodies (mAbs) for CD16 (FcgammaRIII) plays a central role in the ability of the mAb to mediate antitumor activity. We evaluated how CD16 polymorphisms, and mAb with modified affinity for target antigen and CD16, affect natural killer (NK) cell phenotype when CD20(+) malignant B cells were also present. The mAb consisted of rituximab (R), anti-CD20 with enhanced affinity for CD20 (AME-B), and anti-CD20 with enhanced affinity for both CD20 and CD16 (AME-D). Higher concentrations of mAb were needed to induce CD16 modulation, CD54 up-regulation, and antibody-dependent cellular cytotoxicity (ADCC) on NK cells from subjects with the lower affinity CD16 polymorphism. The dose of mAb needed to induce NK activation was lower with AME-D irrespective of CD16 polymorphism. At saturating mAb concentrations, peak NK activation was greater for AME-D. Similar results were found with measurement of CD16 modulation, CD54 up-regulation, and ADCC. These data demonstrate that cells coated with mAb with enhanced affinity for CD16 are more effective at activating NK cells at both low and saturating mAb concentrations irrespective of CD16 polymorphism, and they provide further evidence for the clinical development of such mAbs with the goal of improving clinical response to mAb.

Abstract
B cells currently are not viewed as being capable of producing granzyme B or being cytotoxic. We found that B-chronic lymphocytic leukemia (B-CLL) cells treated with interleukin-21 (IL-21) produce low levels of granzyme B. The addition of either CpG oligodeoxynucleotide (ODN) or anti-B-cell-receptor antibody (anti-BCR) to IL-21 results in enhanced production of functional granzyme B by B-CLL cells. B-CLL cells treated with IL-21 and CpG ODN undergo apoptosis and are able to induce apoptosis of untreated bystander B-CLL cells. This effect can be inhibited by anti-granzyme B antibody. Benign human B cells, Epstein-Barr virus (EBV)-transformed lymphoblasts, and many standard lymphoma cell lines produce high levels of granzyme B in response to IL-21 and anti-BCR. Our results suggest that the ability to induce production of functional granzyme B by B cells could open new approaches to the therapy of B-CLL and other B-cell malignancies. Our findings also have significant implications for our understanding of the role of B cells for immune regulation and for a variety of immune phenomena, including cancer immunity, autoimmunity, and infectious immunity.

Abstract
Non-Hodgkin's lymphoma (NHL) is a group of malignancies with heterogeneous genetic and epigenetic alterations. Discovery of molecular markers that better define NHL should improve diagnosis, prognosis and understanding of the biology. We developed a CpG island DNA microarray for discovery of aberrant methylation targets in cancer, and now apply this method to examine NHL cell lines and primary tumors. This methylation profiling revealed differential patterns in six cell lines originating from different subtypes of NHL. We identified 30 hypermethylated genes in these cell lines and independently confirmed 10 of them. Methylation of 6 of these genes was then further examined in 75 primary NHL specimens composed of four subtypes representing different stages of maturation. Each gene (DLC-1, PCDHGB7, CYP27B1, EFNA5, CCND1 and RARbeta2) was frequently hypermethylated in these NHLs (87, 78, 61, 53, 40 and 38%, respectively), but not in benign follicular hyperplasia. Although some genes such as DLC-1 and PCDHGB7 were methylated in the vast majority of NHLs, others were differentially methylated in specific subtypes. The methylation of the candidate tumor suppressor gene DLC-1 was detected in a high proportion of primary tumor and plasma DNA samples by using quantitative methylation-specific PCR analysis. This promoter hypermethylation inversely correlated with DLC-1 gene expression in primary NHL samples. Thus, this CpG island microarray is a powerful discovery tool to identify novel methylated genes for further studies of their relevant molecular pathways in NHLs and identification of potential epigenetic biomarkers of disease.

Abstract
Purpose Despite several new treatment options, single- and multi-institution analyses have not clarified whether survival patterns in follicular lymphoma (FL) patients have changed in recent decades. We undertook a study using a large population-based registry to analyze survival patterns among patients with FL. Patients and Methods Surveillance, Epidemiology, and End Results morphology codes were used to identify 14,564 patients diagnosed with FL between 1978 and 1999. Observed median survival times, Kaplan-Meier survival curves, proportional death hazard ratios, and relative survival rates were calculated. Joinpoint regression analysis was used to identify trends in annual adjusted death hazard ratios. Results An improvement in survival of all patients with FL was observed between each of three diagnosis eras (1978 to 1985, 1986 to 1992, and 1993 to 1999) by log-rank tests. Among patients with stage-specific data, the median survival time improved from 84 months (95% CI, 81 to 88 months) in the 1983 to 1989 era to 93 months (95% CI, 89 to 97 months) in the 1993 to 1999 era. Similar findings were identified across sex and age groups and for subsets including advanced-stage, large-cell FL and the combined subset of small cleaved- and mixed-cell FL. The inter-era survival advantage observed in white patients was not observed for black patients. The relative risk of death decreased by 1.8% per year over the 1983 to 1999 observation period. Conclusion The survival of patients with FL in the United States has improved over the last 25 years. The survival improvement may be a result of the sequential application of effective therapies and improved supportive care.

Abstract
Immunostimulatory CpG-containing oligodeoxynucleotides (CpG ODN) have a number of effects on B cells, including upregulation of immunogenic molecules, and, therefore, appear attractive as potential components of immunotherapy for B cell chronic lymphocytic leukemia (B-CLL). Previous in vitro studies investigating the effect of CpG ODN on B-CLL cells used serum-low conditions and did not account for the longer-half life of CpG ODN in vitro. The present study was designed to explore how the presence of serum and exposure time affect CpG ODN-mediated changes on B-CLL cells. The optimal concentration for CpG ODN-mediated effects in the presence of 100% serum or plasma was higher (10-20 microg/ml) than for serum-low conditions. Maximal CpG ODN-mediated effects required the presence of ODN for no longer than 3 hours. The inhibition of CpG ODN-mediated effects by serum correlated with lower uptake of ODN into B-CLL cells in the presence of serum. A threshold effect on biologic response was observed, with a given amount of ODN internalized, resulting in phenotypic changes. In conclusion, systemic short-term application of CpG ODN appears to be sufficient to induce phenotypic changes, but higher doses of CpG ODN than previously thought may be necessary because of inhibition of their uptake by serum.

Abstract
Chromosomal abnormalities in B-cell chronic lymphocytic leukemia (B-CLL) have been shown to correlate with prognosis. Little is known about the relationship between chromosomal abnormalities and biological behavior of B-CLL cells in vitro. The present study was designed to explore the impact of chromosomal abnormalities determined by interphase fluorescence in situ hybridization (FISH) on the in vitro survival and immunogenicity of B-CLL. Considerable heterogeneity was noted in the in vitro survival and expression of costimulatory, adhesion, and antigen-presenting molecules by B-CLL cells. Spontaneous apoptosis of B-CLL cells in vitro was significantly lower in samples with good prognosis cytogenetics when compared to samples with poor prognosis cytogenetics. In contrast, B-CLL cells from samples with good prognosis cytogenetics exhibited higher basal expression of molecules involved in costimulation, cellular adhesion, and antigen presentation, and induced significantly more T-cell proliferation in mixed lymphocyte cultures. We conclude that chromosomal aberrations of B-CLL cells correlate with the in vitro biological behavior of B-CLL. Our data indicate that good prognosis cytogenetics correlates with less spontaneous apoptosis but greater in vitro immunogenicity. These findings could have significant implications on the design of future therapeutic approaches in patients with CLL, and the likelihood of response based on cytogenetics.

Abstract
PURPOSE To determine whether a response classification based on integration of fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET) into the International Workshop Criteria (IWC) provides a more accurate response assessment than IWC alone in patients with non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Fifty-four patients with aggressive NHL who underwent FDG-PET and computed tomography 1 to 16 weeks after four to eight cycles of chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone were assessed for complete response (CR), unconfirmed CR (CRu), partial response (PR), stable disease (SD), and progressive disease (PD) by the IWC and by integrated IWC and FDG-PET (IWC+PET). Progression-free survival (PFS) was also compared between IWC- and IWC+PET-assigned response designations. RESULTS By IWC, 17 patients had a CR, seven had a CRu, 19 had a PR, nine had SD, and two had PD. In comparison, by IWC+PET, 35 patients had a CR, 12 had a PR, six had SD, one had PD, and zero had a CRu. In separate multivariate models, PFS was significantly shorter in patients with PR than in those with a CR using IWC (hazard ratio [HR], 8.9; P = .021) or IWC+PET (HR, 29.7; P = .0003). However, when the two classifications were included in the same multivariate model, only IWC+PET was a statistically significant independent predictor for PFS (P = .008 v P = .72 for IWC). In addition, when patients with a PR by IWC and a CR by IWC+PET were compared with those with a CR by IWC and a CR by IWC+PET, there was no significant difference in PFS (HR, 1.6; P = .72), indicating that IWC+PET identified a subset of IWC-PR patients with a more favorable prognosis. CONCLUSION Compared with IWC, the IWC+PET-based assessment provides a more accurate response classification in patients with aggressive NHL.

Abstract
Immunostimulatory oligodeoxynucleotides (IS ODN) can mediate a number of immunologic effects. We previously demonstrated that treatment of B cell chronic lymphocytic leukemia (B-CLL) cells with one class of IS ODN, CpG ODN, alters their phenotype and increases their immunogenicity. Here, we demonstrate that in contrast to the classic understanding of CpG ODN as inhibitors of B cell apoptosis, IS ODN including CpG ODN induce apoptosis in B-CLL cells. It is important that these changes are seen not only with CpG ODN but with ODN that lack the classical CpG motif. B-CLL cells from 20 subjects were treated in vitro with IS ODN for up to 7 days. IS ODN treatment resulted in increased numbers of apoptotic cells in 13 out of 20 B-CLL samples. IS ODN enhanced apoptosis in samples with 13q deletion as a single aberration and had a heterogeneous effect on apoptosis in samples with other aberrations including 17p deletion, 11q deletion, or trisomy 12. Induction of apoptosis did not correlate with expression of the CpG ODN receptor Toll-like receptor 9. Apoptosis was dependent on the activation of caspases and was accompanied by up-regulation of CD95/Fas and its ligand. We conclude that IS ODN including CpG ODN can induce apoptosis of most B-CLL samples. The ability of IS ODN to induce apoptosis differs based on cytogenetic status. Up-regulation of CD95/Fas may play a role in IS ODN-induced apoptosis of B-CLL.

Abstract
PURPOSE OF REVIEW Cancer treatment is entering an era of targeted approaches. One such approach is use of the immune system to recognize and eliminate malignant cells. Synthetic CpG oligonucleotides (CpG DNA) are a relatively new class of agents that have the ability to stimulate a potent, orchestrated tumor-specific immune response. This review provides an overview of the immunologic effects of CpG DNA and summarizes the results of preclinical investigations that have led to ongoing development of CpG DNA as a component of clinical cancer immunotherapy. RECENT FINDINGS New studies demonstrate that at least three classes of CpG DNA sequences exist, each with different physical characteristics and biologic effects. Preliminary studies in several animal models of cancer suggest that CpG DNA have the ability to induce tumor regression by activating innate immunity, enhancing antibody dependent cellular cytotoxicity, and serving as potent vaccine adjuvants that elicit a specific, protective immune response. SUMMARY Animal models suggest that CpG DNA may have many uses in cancer immunotherapy. Early clinical trials suggest that CpG DNA can be administered safely to humans, and studies are ongoing to understand how these agents may play a role in cancer immunotherapy.

Abstract
Hodgkin's lymphoma and aggressive non-Hodgkin's lymphoma (NHL) are common, potentially curable cancers. Despite modern therapy, many patients will relapse. A number of relapsing patients may be cured with subsequent treatment, including high-dose chemotherapy. Risk of relapse after potentially curative therapy is greatest in the first 2 years, and post-treatment surveillance should be concentrated during this time. Most patients will present with symptoms or physical findings at relapse. Physicians and patients should be aware of common symptoms associated with relapse, and laboratory and radiological testing should be used to assess such concerns.

Abstract
Despite the fact that there are only a few controlled trials demonstrating the benefits associated with the use of corticosteroids in specific situations, these agents are administered frequently to patients with advanced cancer. Corticosteroids may be used alone or as adjuvants in combination with other palliative or antineoplastic treatments. For example, corticosteroids may help prevent nausea, vomiting, and hypersensitivity reactions to treatment with chemotherapy or radiation. They are also commonly used as appetite stimulants in patients with advanced cancer. In the adjuvant setting, corticosteroids help to alleviate pain in advanced cancer patients, including specific situations such as back pain related to epidural compression. This article reviews the evidence supporting the use of corticosteroids in a broad range of situations seen in patients with advanced cancer.

Abstract
T cells play a key role in the control of abnormal B cell proliferation. Factors that play a role in inadequate T cell responses include absence of expression of costimulatory and adhesion molecules by the malignant B cells and lack of cytotoxic T cells specific for tumor-associated antigens. A number of approaches have been used to enhance T cell response against malignant B cells. Agents such as soluble CD40 ligand can enhance expression of costimulatory molecules by the malignant B cells and improve their ability to activate T cells. Anti-CD3-based bispecific antibodies can retarget T cells toward the tumor cells irrespective of T cell specificity. We used the V 38C13 murine lymphoma model to assess whether the combination of soluble CD40 ligand and anti-CD3-based bispecific antibody can enhance T cell activation induced by malignant B cells more effectively than either approach alone. Expression of CD80, CD86, and ICAM-1 on lymphoma cells was up-regulated by soluble CD40 ligand. Syngeneic T cells were activated more extensively by lymphoma cells when the lymphoma cells were pre-treated with soluble CD40 ligand. Bispecific-antibody induced T cell activation was more extensive when lymphoma cells pretreated with soluble CD40 ligand were present. The combination of soluble CD40 ligand plus bispecific antibody enhanced the median survival of mice compared to mice treated with bispecific antibody alone. We conclude that pretreatment of tumor cells with agents capable of inducing costimulatory molecule expression, such as soluble CD40 ligand can enhance the ability of malignant B cells to activate T cells. This effect is enhanced by the addition of bispecific antibody. The combination of enhanced expression of costimulatory molecules and retargeting of T cells by bispecific antibody may allow for a more effective T-cell-based immunotherapy.

Abstract
Recent advances in our understanding of the immune response are allowing for the logical design of new approaches to cancer immunization. One area of interest is the development of new immune adjuvants. Immunostimulatory oligodeoxynucleotides containing the CpG motif (CpG ODN) can induce production of a wide variety of cytokines and activate B cells, monocytes, dendritic cells, and NK cells. Using the 38C13 B cell lymphoma model, we assessed whether CpG ODN can function as immune adjuvants in tumor antigen immunization. The idiotype served as the tumor antigen. Select CpG ODN were as effective as complete Freund's adjuvant at inducing an antigen-specific antibody response but were associated with less toxicity. These CpG ODN induced a higher titer of antigen-specific IgG2a than did complete Freund's adjuvant, suggesting an enhanced TH1 response. Mice immunized with CpG ODN as an adjuvant were protected from tumor challenge to a degree similar to that seen in mice immunized with complete Freund's adjuvant. We conclude that CpG ODN are effective as immune adjuvants and are attractive as part of a tumor immunization strategy.

Abstract
Bacterial DNA and synthetic oligodeoxynucleotides containing the CpG motif (CpG ODN) can activate various immune cell subsets, including natural killer cells and macrophages. We evaluated whether the combination of CpG ODN and antitumor monoclonal antibody is effective at preventing tumor growth in an immunocompetent murine lymphoma model. CpG ODN-activated murine splenocytes induced lysis of tumor targets more effectively than unactivated splenocytes. These effector cells were also superior to unactivated splenocytes or cells activated with a control methylated ODN at inducing antibody-mediated lysis of 38C13 murine lymphoma cells. In vivo, CpG ODN alone had no effect on survival of mice inoculated with 38C13 cells. However, a single injection of CpG ODN enhanced the antitumor response to antitumor monoclonal antibody therapy. Ninety percent of mice treated with monoclonal antibody alone developed tumor compared with 20% of mice treated with antibody and CpG ODN. These antitumor effects were less pronounced when treatment consisted of an identical ODN containing methylated CpG dinucleotides. A single dose of CpG ODN appeared to be as effective as multiple doses of interleukin-2 at inhibiting tumor growth when combined with antitumor monoclonal antibody. We conclude that immunostimulatory CpG ODN can enhance antibody dependent cellular cytotoxicity and warrant further evaluation as potential immunotherapeutic reagents in cancer.
