Abstract
There has been a collaborative global effort to construct novel therapeutic and prophylactic approaches to SARS-CoV-2 management. Although vaccine development is crucial, acute management of newly infected patients, especially those with severe acute respiratory distress syndrome, is a priority. Herein we describe the rationale and potential of repurposing a dual plasmid, Vigil (pbi-shRNAfurin-GM-CSF), now in Phase III cancer trials, for the treatment of and, in certain circumstances, enhancement of the immune response to SARS-CoV-2.

Abstract
Chimeric antigen receptor (CAR) modified T-cell therapy, a unique platform technology highlighting precision medicine through utilization of molecular biology and cell-based therapeutics has shown unprecedented rates in patients with hematological malignancies such as acute lymphocyte leukemia, non-Hodgkin's lymphoma and multiple myeloma (MM). With the approval of CD19-targeted CAR T-cells by the Food and Drug Administration in acute lymphoblastic leukemia (ALL) and NHL, this technology is positioned for aggressive expansion to combination therapeutic opportunities and proof of principle towards utility in other malignant disorders. However, despite the impressive results seen with hematological malignancies, CAR T-cells have shown limited efficacy in solid tumors with several unsuccessful preclinical studies. Regardless, these attempts have provided us with a better understanding of the imminent challenges specific to solid tumors even if they have not so far led to expanded clinical treatment opportunities outside ALL/NHL/MM. This review summarizes our current understanding of CAR T-cell mechanism of action, while presenting the major limitations of CAR T-cell derived treatments in solid tumors. We further discuss recent findings and present new potential strategies to overcome the challenges facing solid tumor targeting by CAR T-cell platforms.

Abstract
Histone lysine acetylation is critical in regulating transcription. Dysregulation of this process results in aberrant gene expression in various diseases, including cancer. The bromodomain, present in several proteins, recognizes promotor lysine acetylation and recruits other transcription factors. The bromodomain extra-terminal (BET) family of proteins consists of four conserved mammalian members that regulate transcription of oncogenes such as MYC and the NUT fusion oncoprotein. Targeting the acetyl-lysine-binding property of BET proteins is a potential therapeutic approach of cancer. Consequently, following the demonstration that thienotriazolodiazepine small molecules effectively inhibit BET, clinical trials were initiated. We thus discuss the mechanisms of action of various BET inhibitors and the prospects for their clinical use as cancer therapeutics.

Abstract
Stathmin-1 (STMN1) is a microtubule-destabilizing protein which is overexpressed in cancer. Its overexpression is associated with poor prognosis and also serves as a predictive marker to taxane therapy. We have developed a proprietary bi-functional shRNA (bi-shRNA) platform to execute RNA interference (RNAi)-mediated gene silencing and a liposome-carrier complex to systemically deliver the pbi-shRNA plasmids. In vitro and in vivo testing demonstrated efficacy and specificity of pbi-shRNA plasmid in targeting STMN1 (Phadke, A. P., Jay, C. M., Wang, Z., Chen, S., Liu, S., Haddock, C., Kumar, P., Pappen, B. O., Rao, D. D., Templeton, N. S., et al. (2011). In vivo safety and antitumor efficacy of bifunctional small hairpin RNAs specific for the human Stathmin 1 oncoprotein. DNA Cell Biol. 30, 715-726.). Biodistribution and toxicology studies in bio-relevant Sprague Dawley rats with pbi-shRNA STMN1 lipoplex revealed that the plasmid DNA was delivered to a broad distribution of organs after a single subcutaneous injection. Specifically, plasmid was detected within the first week using QPCR (threshold 50 copies plasmid/1 µg genomic DNA) at the injection site, lung, spleen, blood, skin, ovary (limited), lymph nodes, and liver. It was not detected in the heart, testis or bone marrow. No plasmid was detected from any organ 30 days after injection. Treatment was well tolerated. Minimal inflammation/erythema was observed at the injection site. Circulating cytokine response was also examined by ELISA. The IL-6 levels were induced within 6 h then declined to the vehicle control level 72 h after the injection. TNFα induction was transiently observed 4 days after the DNA lipoplex treatment. In summary, the pbi-shRNA STMN1 lipoplex was well tolerated and displayed broad distribution after a single subcutaneous injection. The pre-clinical data has been filed to FDA and the pbi-shRNA STMN1 lipoplex is being investigated in a phase I clinical study.

Abstract
Ewing's sarcoma is a devastating rare pediatric cancer of the bone. Intense chemotherapy temporarily controls disease in most patients at presentation but has limited effect in patients with progressive or recurrent disease. We previously described preliminary results of a novel immunotherapy, FANG (Vigil) vaccine, in which 12 advanced stage Ewing's patients were safely treated and went on to achieve a predicted immune response (IFNγ ELISPOT). We describe follow-up through year 3 of a prospective, nonrandomized study comparing an expanded group of Vigil-treated advanced disease Ewing's sarcoma patients (n = 16) with a contemporaneous group of Ewing's sarcoma patients (n = 14) not treated with Vigil. Long-term follow-up results show a survival benefit without evidence of significant toxicity (no ≥ grade 3) to Vigil when administered once monthly by intradermal injection (1 × 10e(6) cells/injection to 1 × 10e(7) cells/injection). Specifically, we report a 1-year actual survival of 73% for Vigil-treated patients compared to 23% in those not treated with Vigil. In addition, there was a 17.2-month difference in overall survival (OS; Kaplan-Meier) between the Vigil (median OS 731 days) and no Vigil patient groups (median OS 207 days). In conclusion, these results supply the rational for further testing of Vigil in advanced stage Ewing's sarcoma.

Abstract
BACKGROUND Imprime PGG (β(1,6)-[poly-(1,3)-D-glucopyranosyl]-poly-β(1,3)-D-glucopyranose) is an innate immune cell modulator that primes neutrophils and monocytes/macrophages to exert antitumor activity against complement opsonized tumor cells. In patients with KRAS-mutant colorectal cancer (CRC), cetuximab alone is ineffective; however, it can bind to tumor cells and induce opsonization for recognition by Imprime PGG-bound innate immune cells. The primary objective of this study was to determine the antitumor activity of Imprime PGG in combination with cetuximab in patients with KRAS-mutant metastatic CRC. PATIENTS AND METHODS The study had a 2-stage Simon optimal design with 80% power to detect a target objective response rate (ORR) of ≥10% at a 10% significance level. Patients received weekly Imprime PGG (4 mg/kg) and cetuximab (loading dose, 400 mg/m(2), then 250 mg/m(2)) intravenously. The primary end point was ORR; secondary end points included duration of response (DOR), time to progression (TTP), overall survival (OS), disease control rate, progression-free survival, and safety. Stage 1 of the study was to enroll 17 evaluable patients. RESULTS One partial response (5.6%) was observed among 18 patients enrolled into stage 1. Median DOR was 4.2 months, TTP 2.7 months, and OS 6.6 months. Overall, observed toxicity was as expected from cetuximab alone. The most common (≥20%) adverse events related to Imprime PGG were fatigue (7 patients; 38.9%), infusion reaction (4 patients; 22.2%), and headache (4 patients; 22.2%). There was no Grade 4 toxicity nor treatment-related deaths. CONCLUSION Imprime PGG in combination with cetuximab treatment in patients with KRAS-mutant CRC showed compelling, albeit modest, clinical activity. This study provides proof of principle that Imprime PGG, in combination with complement-activating antibodies, is associated with clinical activity.

Abstract
Purpose Talimogene laherparepvec (T-VEC) is a herpes simplex virus type 1–derived oncolytic immunotherapy designed to selectively replicate within tumors and produce granulocyte macrophage colony-stimulating factor (GM-CSF) to enhance systemic antitumor immune responses. T-VEC was compared with GM-CSF in patients with unresected stage IIIB to IV melanoma in a randomized open-label phase III trial. Patients and Methods Patients with injectable melanoma that was not surgically resectable were randomly assigned at a two-to-one ratio to intralesional T-VEC or subcutaneous GM-CSF. The primary end point was durable response rate (DRR; objective response lasting continuously ≥ 6 months) per independent assessment. Key secondary end points included overall survival (OS) and overall response rate. Results Among 436 patients randomly assigned, DRR was significantly higher with T-VEC (16.3%; 95% CI, 12.1% to 20.5%) than GM-CSF (2.1%; 95% CI, 0% to 4.5%]; odds ratio, 8.9; P < .001). Overall response rate was also higher in the T-VEC arm (26.4%; 95% CI, 21.4% to 31.5% v 5.7%; 95% CI, 1.9% to 9.5%). Median OS was 23.3 months (95% CI, 19.5 to 29.6 months) with T-VEC and 18.9 months (95% CI, 16.0 to 23.7 months) with GM-CSF (hazard ratio, 0.79; 95% CI, 0.62 to 1.00; P = .051). T-VEC efficacy was most pronounced in patients with stage IIIB, IIIC, or IVM1a disease and in patients with treatment-naive disease. The most common adverse events (AEs) with T-VEC were fatigue, chills, and pyrexia. The only grade 3 or 4 AE occurring in ≥ 2% of T-VEC–treated patients was cellulitis (2.1%). No fatal treatment-related AEs occurred. Conclusion T-VEC is the first oncolytic immunotherapy to demonstrate therapeutic benefit against melanoma in a phase III clinical trial. T-VEC was well tolerated and resulted in a higher DRR (P < .001) and longer median OS (P = .051), particularly in untreated patients or those with stage IIIB, IIIC, or IVM1a disease. T-VEC represents a novel potential therapy for patients with metastatic melanoma.

Abstract
Stathmin1 (STMN1) is a microtubule modulator that is expressed in multiple cancers and correlates with poor survival. We previously demonstrated in vivo safety of bifunctional (bi) shRNA STMN1 bilamellar invaginated vesicle (BIV) and that systemic delivery correlated with antitumor activity. Patients with superficial advanced refractory cancer with no other standard options were entered into trial. Study design involved dose escalation (four patients/cohort) using a modified Fibonacci schema starting at 0.7 mg DNA administered via single intratumoral injection. Biopsy at baseline, 24/48 hours and resection 8 days after injection provided tissue for determination of cleavage product using next-generation sequencing (NGS) and reverse transcription quantitative polymerase chain reaction (RT-qPCR), 5' RLM rapid amplification of cDNA ends (RACE) assay. Serum pharmacokinetics of circulating plasmid was done. Twelve patients were entered into three dose levels (0.7, 1.4, 7.0 mg DNA). No ≥ grade 3 toxic effects to drug were observed. Maximum circulating plasmid was detected at 30 seconds with less than 10% detectable in all subjects at 24 hours. No toxic effects were observed. Predicted cleavage product was detected by both NGS (n = 7/7 patients analyzed, cohorts 1, 2) and RLM RACE (n = 1/1 patients analyzed cohort 3). In conclusion, bi-shRNA STMN1 BIV is well tolerated and detection of mRNA target sequence-specific cleavage product confirmed bi-shRNA BIV mechanism of action.

Abstract
BACKGROUND This phase I, dose-finding study determined the safety, maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D), and antitumor activity of PX-866, a phosphatidylinositol 3-kinase inhibitor, combined with cetuximab in patients with incurable colorectal cancer or squamous cell carcinoma of the head and neck. METHODS PX-866 was administered at escalating doses (6-8 mg daily) combined with cetuximab given at a 400 mg/m(2) loading dose followed by 250 mg/m(2) weekly. A "3 + 3" study design was used. Prior therapy with anti-EGFR therapies, including cetuximab, was allowed. RESULTS Eleven patients were enrolled. The most frequent treatment-emergent adverse event was diarrhea (90.1%), followed by hypomagnesemia (72.2%), vomiting (72.2%), fatigue (54.5%), nausea (54.5%), rash (45.5%) and peripheral edema (40%). No dose limiting toxicities were observed. The RP2D was 8 mg, the same as the single-agent PX-866 MTD. Best responses in 9 evaluable patients were: 4 partial responses (44.4%), 4 stable disease (44.4%), and 1 disease progression (11.1%). The median progression free survival was 106 days (range: 1-271). CONCLUSION Treatment with PX-866 and cetuximab was tolerated with signs of anti-tumor activity. Further development of this combination is warranted.

Abstract
RNA interference (RNAi) represents a powerful, new tool for scientific investigation as well as a promising new form of targeted gene therapy, with applications currently in clinical trials. Bifunctional short hairpin RNA (shRNA) are synthetic RNAi molecules, engineered to utilize multiple endogenous RNAi pathways to specifically silence target genes. Pancreatic and duodenal homeobox 1 (PDX1) is a key regulator of pancreatic development, β-cell differentiation, normal β-cell function and pancreatic cancer. Our aim is to review the process of identifying PDX1 as a specific, potential RNAi target in pancreatic cancer, as well as the underlying mechanisms and various forms of RNAi, with subsequent testing and development of PDX1-targeted bifunctional shRNA therapy.

Abstract
Background: This phase I, dose-finding study determined the safety, maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D), pharmacokinetics, and antitumour activity of PX-866, a phosphatidylinositol 3-kinase inhibitor, combined with docetaxel in patients with incurable solid tumours. Methods: PX-866 was administered at escalating doses (4–8 mg daily) with docetaxel 75 mg m−2 intravenously every 21 days. Archived tumour tissue was assessed for potential predictive biomarkers. Results: Forty-three patients were enrolled. Most adverse events (AEs) were grade 1 or 2. The most frequent study drug-related AE was diarrhoea (76.7%), with gastrointestinal disorders occurring in 79.1% (docetaxel-related) and 83.7% (PX-866-related). No dose-limiting toxicities were observed. The RP2D was 8 mg, the same as the single-agent MTD. Co-administration of PX-866 and docetaxel did not affect either drug's PKs. Best responses in 35 evaluable patients were: 2 partial responses (6%), 22 stable disease (63%), and 11 disease progression (31%). Eleven patients remained on study for >180 days, including 8 who maintained disease control on single-agent PX-866. Overall median progression-free survival (PFS) was 73.5 days (range: 1–569). A non-significant association between longer PFS for PIK3CA-MUT/KRAS-WT vs PIK3CA-WT/KRAS-WT was observed. Conclusion: Treatment with PX-866 and docetaxel was well tolerated, without evidence of overlapping/cumulative toxicity. Further investigation with this combination is justified.

Abstract
Transcription factor pancreatic and duodenal homeobox-1 (PDX-1) plays an essential role in pancreatic development, β-cell differentiation, maintenance of normal β-cell function and tumorigenesis. PDX-1 expression is tightly controlled through a variety of mechanisms under different cellular contexts. We report here that overexpression of Notch1 intracellular domain (NICD), an activated form of Notch1, enhanced PDX-1 expression in both PDX-1 stable HEK293 cells and mouse insulinoma β-TC-6 cells, while NICD shRNA inhibited the enhancing effect. NICD-enhanced PDX-1 expression was accompanied by increased insulin expression/secretion and cell proliferation in β-TC-6 cells, which was reversed by NICD shRNA. Cre activation-induced specific expression of NICD in islet β cells of transgenic βNICD+/+ mice induced increased expression of PDX-1, insulin and proliferating cell nuclear antigen (PCNA) and decreased expression of p27 with accompanied fasting hyperinsulinemia and hypoglycemia and altered responses to intraperitoneal glucose tolerance test. Systemically delivered NICD shRNA suppressed islet expression of PDX-1 and reversed the hypoglycemia and hyperinsulinemia. Moreover, expression levels of NICD were correlated with those of PDX-1 in human pancreatic neuroendocrine tumor. Thus, Notch1 acts as a positive regulator for PDX-1 expression, cooperates with PDX-1 in the development of insulin overexpression and islet cell neoplasia and represents a potential therapeutic target for islet neoplasia.

Abstract
Oncolytic virotherapy is an evolving but, as yet, unrealized treatment option for cancer. This approach harnesses the cancer-restricted replicative activity of engineered viruses to achieve tumor cell kill. Tumors that are resistant to chemotherapy or radiotherapy can be susceptible to viral oncolysis because of distinct cell kill mechanisms. There is now compelling evidence that collateral induction of anti-tumor immune responses contributes substantially to viral antitumor activities. In addition to the expected anti-viral immune clearance, the "danger" signal created by virus-infected cells can generate immune co-stimulation known to override immune suppression and reverse tolerance within the tumor microenvironment. Our recent findings indicate that immune activation augments the clinical outcomes of oncolytic virotherapy. Strikingly similar and robust clinical response rates ( > 25%) were observed among advanced cancer patients following intratumoral treatments with adenoviral (AdΔ24) and herpes simplex (JS1/34.5-/47) constructs armed with an integrated granulocyte-macrophage colony-stimulating factor (GMCSF) payload. Both agents produced regressions in injected as well as distant, uninjected lesions, demonstrating systemic effectiveness. We discuss the innate and adaptive immune activating events that may contribute to these clinical outcomes, and examine systemic delivery strategies to tilt the immunological balance from viral clearance to tumor elimination.

Despite billions of dollars allocated to cancer research, cancer remains the number 2 cause of death in the United States with less than 50% of advanced cancer patients living one year following standard treatment. Cancer is a complex disease both intrinsically and in relation to its host environment. From a molecular standpoint no two cancers are the same despite histotypic similarity. As evidenced by the recent advances in molecular biology, treatment for advanced cancer is headed towards specific targeting of vulnerable signaling nodes within the reconfigured pathways created by "omic" rewiring. With advancements in proteo-genomics and the capacity of bioinformatics, complex tumor biology can now be more effectively and rapidly analyzed to discover the vulnerable high information transfer nodes within individual tumors. RNA interference (RNAi) technology, with its capability to knock down the expression of targeted genes (the vulnerable nodes), is moving into the clinic to target these nodes, which are integral to tumor maintenance, with a low risk of side-effects and to block intrinsic immunosuppressors thereby priming the tumor for immune attack. An RNAi based sequential approach, a so called "one-two punch," is being advocated comprising tumor volume reduction (ideally to minimal residual disease status) effected by integrated multi-target knockdown followed by immune activation. Examples and recent developments are provided to illustrate this highly powerful approach heralding the future of personalized cancer therapy.

Abstract
BACKGROUND The mesenchymal-epithelial transition factor (MET) receptor is dysregulated in hepatocellular carcinoma (HCC), and tivantinib (ARQ 197) is an oral, selective, MET inhibitor. METHODS This Phase-1b study assessed tivantinib safety as primary objective in patients with previously treated HCC and Child-Pugh A or B liver cirrhosis. Patients received oral tivantinib 360 mg twice daily until disease progression or unacceptable toxicity. RESULTS Among 21 HCC patients, common drug-related adverse events (AEs) were neutropaenia, anaemia, asthenia, leucopaenia, anorexia, diarrhoea, and fatigue. No drug-related worsening of liver function or performance status occurred, but one Child-Pugh B patient experienced drug-related bilirubin increase. Four patients had drug-related serious AEs, including one neutropaenia-related death. Haematologic toxicities were more frequent than in previous tivantinib studies but were manageable with prompt therapy. Best response was stable disease (median, 5.3 months) in 9 of 16 evaluable patients (56%). Median time to progression was 3.3 months. CONCLUSION Tivantinib demonstrated a manageable safety profile and preliminary antitumour activity in patients with HCC and Child-Pugh A or B cirrhosis.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy followed by surgery is the primary treatment option for patients with locally advanced esophageal cancer. This multicenter phase I trial examined intratumoral injection of TNFerade biologic, an adenoviral vector that expresses the human tumor necrosis factor-α gene, with chemoradiotherapy in locally advanced esophageal cancer. OBJECTIVES To assess pathologic complete response (pCR), time to disease progression, progression-free survival, survival, and safety and tolerance in patients treated with preoperative chemoradiation combined with endoscopy or EUS-guided intratumoral injection of TNFerade biologic. DESIGN/INTERVENTION Five weekly injections of TNFerade biologic, dose-escalated logarithmically from 4 × 10(8) to 4 × 10(11) particle units (PU), were given in combination with cisplatin 75 mg/m(2) and intravenous 5-fluorouracil 1000 mg/m(2)/d for 96 hours on days 1 and 29, and concurrent radiation therapy to 45 Gy. Surgery was performed 9 to 15 weeks after treatment. SETTING U.S. multicenter study. PATIENTS Patients with stage II and III esophageal cancer were enrolled. MAIN OUTCOME MEASUREMENTS Primary outcome measures were safety, feasibility, tolerability, and rate of pCR. Secondary outcome measures were overall survival (OS) and disease-free survival. RESULTS Twenty-four patients with a median age of 61 years were enrolled; 88% of the patients were men, 21% were stage II, and 79% were stage III. Six (29%) had a pCR, observed among 21 patients (20 who underwent esophagectomy and 1 at autopsy). Dose-limiting toxicities were not observed. The most frequent potentially related adverse events were fatigue (54%), fever (38%), nausea (29%), vomiting (21%), esophagitis (21%), and chills (21%). At the top dose of 4 × 10(11) PU, thromboembolic events developed in 5 of 8 patients. The median OS was 47.8 months. The 3- and 5-year OS rates and disease-free survival rates were 54% and 41% and 38% and 38%, respectively. LIMITATIONS We included primarily adenocarcinoma. CONCLUSIONS Preoperative TNFerade, in combination with chemoradiotherapy, is active and safe at doses up to 4 × 10(10) PU and is associated with long survival. This regimen warrants additional studies.

Abstract
Ewing's sarcoma tumors are associated with chromosomal translocation between the EWS gene and the ETS transcription factor gene. These unique target sequences provide opportunity for RNA interference(i)-based therapy. A summary of RNAi mechanism and therapeutically designed products including siRNA, shRNA and bi-shRNA are described. Comparison is made between each of these approaches. Systemic RNAi-based therapy, however, requires protected delivery to the Ewing's sarcoma tumor site for activity. Delivery systems which have been most effective in preclinical and clinical testing are reviewed, followed by preclinical assessment of various silencing strategies with demonstration of effectiveness to EWS/FLI-1 target sequences. It is concluded that RNAi-based therapeutics may have testable and achievable activity in management of Ewing's sarcoma.

Abstract
BACKGROUND TNFeradeBiologic (AdGVEGR.TNF.11D) is a replication-deficient adenoviral vector that expresses tumor necrosis factor-α (TNF-α) under the control of the Egr-1 promoter, which is inducible by chemotherapy and radiation. OBJECTIVE This study was conducted to determine the maximal tolerated dose of TNFeradeBiologic with standard chemoradiotherapy and preliminary activity and safety of the combination in the treatment of locally advanced pancreatic cancer (LAPC). DESIGN TNFeradeBiologic was injected into locally advanced pancreatic carcinomas by using EUS or percutaneous administration once a week for 5 weeks together with 50.4 Gy radiation and 5-fluorouracil (5-FU) 200 mg/m(2) daily over 5.5 weeks. Dose levels from 4 × 10(9) to 1 × 10(12) particle units (PU) were studied. SETTING Multicentered, academic institutions. PATIENTS Fifty patients with LAPC were treated. INTERVENTIONS Doses of TNFerade Biologic were administered to patients. MAIN OUTCOME MEASUREMENTS Toleration of TNFerade Biologic was measured through toxicity and tumor response, by using the criteria of the Response Evaluation Criteria in Solid Tumors and the World Health Organization, and was reviewed by a central radiology facility. Overall survival and progression-free survival were also measured. RESULTS Dose-limiting toxicities of pancreatitis and cholangitis were observed in 3 patients at the 1 × 10(12) PU dose, making 4 × 10(11) PU the maximum tolerated dose. One complete response, 3 partial responses, and 12 patients with stable disease were noted. Seven patients eventually went to surgery, 6 had clear margins, and 3 survived >24 months. LIMITATIONS This is a Phase 1/2 non-randomized study. CONCLUSIONS Intratumoral delivery of TNFerade Biologic by EUS with fine-needle viral injection or percutaneously, combined with chemoradiation, shows promise in the treatment of LAPC. There appeared to be better clinical outcome at the maximal tolerated dose than at lower doses. The dose of 4 ×10(11) PU TNFerade Biologic was generally well tolerated, with encouraging indications of activity, and will be tested in the randomized phase of this study. Delivery of TNFerade Biologic did not interfere with subsequent surgical resection.

Abstract
Abstract
Background: Inhibition of the EGFR pathway by the monoclonal antibody cetuximab is an important component of treatment for colorectal cancer (CRC) and squamous cell carcinoma of the head and neck (SCCHN). One mechanism of resistance to EGFR inhibition is increased signaling through the PI-3K pathway. PX-866, an irreversible pan-isoform inhibitor of Class 1 PI-3K, is active in models of CRC and direct patient tumor models of SCCHN as a single agent and in combination with EGFR inhibitors. In a Phase 1 study, single agent PX-866 was well tolerated at a maximum tolerated dose (MTD) of 8 mg/day and was associated with anti-tumor activity. Based on these results, a Phase 1/2 study of PX-866 in combination with cetuximab was initiated in patients (pts) with advanced CRC or SCCHN. The phase 1 portion of the study is complete, and is reported here.
Methods: Pts received cetuximab IV once per week at full doses and escalating doses of oral PX-866 once daily on a 21-day cycle using a 3+3 design. Prophylactic treatment for rash was required. Tumor restaging was performed every two cycles. PK assessments included evaluation of cetuximab levels. Archived tissue was collected for biomarker assessment.
Results: 10 pts with CRC and 1 pt with SCCHN enrolled in two dose cohorts of PX-866 (6 mg n=4; 8 mg n=7) with median age 58 yrs (35–82); all ECOG 0/1; and median number of prior systemic treatments 4 (2–8). Seven pts had received prior treatment with an EGFR inhibitor, including 3 and 4 pts each who had received prior cetuximab and panitumumab, respectively, and 1 pt who had received both. There were no DLTs, and the recommended Phase 2 dose included PX-866 at 8 mg/day and full dose weekly cetuximab. The most common adverse events (AEs) included diarrhea, hypomagnesemia, nausea/vomiting, dehydration, fatigue, rash, asthenia, constipation and weight loss, the majority of which were Gr 1/2 in severity. Treatment-related Gr 3/4 AEs were Gr 3 diarrhea (n=1), Gr 3 hyponatremia (n=1) and Gr 3 hypokalemia (n=1). 2 pts had serious AEs of diarrhea considered related to PX-866 alone or the combination with cetuximab. PX-866 had no effect on cetuximab PK compared to historical data. Eight pts were evaluable for response; best response in these pts was 4 PR (50%), 3 SD (38%) and 1 PD (12%), for a disease control rate of 88%. In 5 response-evaluable pts who had previously received an EGFR inhibitor, best response was 1 PR (20%), 3 SD (60%) and 1 PD (20%). The median number of cycles received was 6 (1 to 11), with PD as the most common reason for discontinuation. Biomarker assessments evaluating the presence of PIK3CA and Kras mutations in tumor samples are ongoing and will be presented.
Conclusions: Treatment with PX-866 and cetuximab was well tolerated, with no increase in toxicity of either drug attributable to the combination. The Phase 2 dose of PX-866 in combination with full dose cetuximab is the same as the single agent MTD. The ORR of 50% is encouraging compared to the historical ORR of 11% for single agent cetuximab. The Phase 2 portion of this study comparing PX-866 + cetuximab vs. cetuximab alone in 2 groups of pts (CRC and SCCHN) is now enrolling.

Abstract
PURPOSE On the basis of the hypothesis that the combined expression of immunostimulatory granulocyte macrophage colony stimulating factor (GM-CSF) and antitumor suppressor TGF-β2 antisense (AS) transgenes can break tolerance and stimulate immune responses to cancer-associated antigens, we constructed an expression plasmid [the tumor-associated glycoprotein (TAG) plasmid] that coexpresses GM-CSF and TGF-β2 AS nucleotide sequences and which was incorporated into an autologous whole-cell vaccine. EXPERIMENTAL DESIGN Patients undergoing resection were enrolled. Freshly harvested autologous tumor cells were mechanically and enzymatically disaggregated, then electroporated with the TAG vector. The resulting vaccine was irradiated, then aliquoted and cryopreserved until the time of injection. Patients received a minimum of 5 to a maximum of 12 monthly intradermal injections. Immune function was monitored at baseline and at months 3 and 6. RESULTS Vaccine manufacturing efficiency was 84% (32/38). Twenty-three patients received at least 1 vaccination. There were no grade 3 or 4 toxicities, and grade 1 and 2 events were local in nature. Seventeen of 21 patients had stable disease (SD) at month 2 or later as their best response, and 1 patient with stage IVa malignant melanoma achieved a complete response (CR) following 11 vaccinations and remains without evidence of disease 2 years following initiation of therapy. Six of 13 patients displayed a positive enzyme-linked immunospot (ELISPOT) response to autologous TAG vaccine at week 12 including 3 patients with prolonged SD or CR. The 3 other patients survived through week 24, as compared with none of the 7 ELISPOT-negative patients. CONCLUSIONS On the basis of safety and clinical and immunologic results, further evaluation of bifunctional vaccines is warranted.

Abstract
BACKGROUND Tivantinib, an oral, non-ATP competitive, selective c-MET inhibitor, exhibited antitumor activity in preclinical models. This open-label, phase I, dose-escalation study evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of tivantinib in patients with advanced or metastatic solid tumors refractory to standard therapy. METHODS Thirteen dose levels of tivantinib ranging from 10 to 360 mg twice a day were administered to patient cohorts in 21-day cycles (14 days on/7 days off); three active pharmaceutical ingredient forms of tivantinib (amorphous, crystalline A, and crystalline B) were also investigated. Treatment was continued until the occurrence of unacceptable toxicity, tumor progression, patient withdrawal, or death. RESULTS A total of 79 patients with advanced solid tumors were enrolled. A maximum tolerated dose was not determined. Tivantinib was well tolerated, with mild to moderate toxicities. Two patients discontinued the study drug due to treatment-emergent adverse events. Dose-limiting grade of 3 or more toxicities including leukopenia, neutropenia, thrombocytopenia, vomiting, and dehydration, were observed in 2 patients treated with tivantinib 360 mg twice a day. The rate of absorption of tivantinib peaked approximately 2 to 4 hours after initial dosing, followed by a linear decrease in plasma concentrations. Increases in tivantinib exposure were not dose proportional. There was significant interpatient pharmacokinetic variability; however the clinical safety of tivantinib seemed unaffected. Three patients (3.8%) achieved a partial response and 40 patients (50.6%) maintained stable disease for a median of 19.9 weeks. CONCLUSIONS Tivantinib 360 mg twice a day was well tolerated in patients with refractory advanced solid tumors. The results of this trial warrant further clinical investigation.

Abstract
Bifunctional small hairpin RNAs (bi-shRNAs) are functional miRNA/siRNA composites that are optimized for posttranscriptional gene silencing through concurrent mRNA cleavage-dependent and -independent mechanisms (Rao et al., 2010 ). We have generated a novel bi-shRNA using the miR30 scaffold that is highly effective for knockdown of human stathmin (STMN1) mRNA. STMN1 overexpression well documented in human solid cancers correlates with their poor prognosis. Transfection with the bi-shSTMN1-encoding expression plasmid (pbi-shSTMN1) markedly reduced CCL-247 human colorectal cancer and SK-Mel-28 melanoma cell growth in vitro (Rao et al., 2010 ). We now examine in vivo the antitumor efficacy of this RNA interference-based approach with human tumor xenografted athymic mice. A single intratumoral (IT) injection of pbi-shSTMN1 (8 μg) reduced CCL-247 tumor xenograft growth by 44% at 7 days when delivered as a 1,2-dioleoyl-3-trimethyl-ammoniopropane:cholesterol liposomal complex. Extended growth reductions (57% at day 15; p < 0.05) were achieved with three daily treatments of the same construct. STMN1 protein reduction was confirmed by immunoblot analysis. IT treatments with pbi-shSTMN1 similarly inhibited the growth of tumorgrafts derived from low-passage primary melanoma (≥70% reduction for 2 weeks) and abrogated osteosarcoma tumorgraft growth, with the mature bi-shRNA effector molecule detectable for up to 16 days after last injection. Antitumor efficacy was evident for up to 25 days posttreatment in the melanoma tumorgraft model. The maximum tolerated dose by IT injection of >92 μg (Human equivalent dose [HED] of >0.3 mg/kg) in CCL-247 tumor xenograft-bearing athymic mice was ∼10-fold higher than the extrapolated IC(50) of 9 μg (HED of 0.03 mg/kg). Healthy, immunocompetent rats were used as biorelevant models for systemic safety assessments. The observed maximum tolerated dose of <100 μg for intravenously injected pbi-shSTMN1 (mouse equivalent of <26.5 μg; HED of <0.09 mg/kg) confirmed systemic safety of the therapeutic dose, hence supporting early-phase assessments of clinical safety and preliminary efficacy.

Abstract
Hereditary inclusion body myopathy (HIBM) is an autosomal recessive adult-onset myopathy due to mutations in the GNE (UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase) gene. Affected patients have no therapeutic options. We have previously demonstrated in preclinical testing the ability to safely correct GNE gene function through liposomal delivery of the wild-type GNE gene. Results were verified in a single patient treated by intravenous infusion of GNE gene lipoplex. A single patient (patient 001) with severe HIBM treated with a compassionate investigational new drug received seven doses of GNE gene lipoplex via intravenous infusion at the following doses: 0.4, 0.4, 1.0, 4.0, 5.0, 6.0, and 7.0 mg of DNA. GNE transgene expression, downstream induction of sialic acid, safety, and muscle function were evaluated. Transient low-grade fever, myalgia, tachycardia, transaminase elevation, hyponatremia, and hypotension were observed after infusion of each dose of GNE gene lipoplex. Quadriceps muscle expression of the delivered GNE, plasmid, and RNA was observed 24 hr after the 5.0-mg dose and at significantly greater levels 72 hr after the 7.0-mg infusion in comparison with expression in quadriceps muscle immediately before infusion. Sialic acid-related proteins were increased and stabilization in the decline of muscle strength was observed. We conclude that clinical safety and activity have been demonstrated with intravenous infusion of GNE gene lipoplex. Further assessment will involve a phase I trial of intravenous administration of GNE gene lipoplex in individuals with less advanced HIBM with more muscle function.

Abstract
BACKGROUND Hereditary inclusion body myopathy (HIBM) is an autosomal recessive adult onset myopathy. It is characterized by mutations of the GNE (UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase) gene. Afflicted patients have no therapeutic options. In preclinical testing, we have previously demonstrated the ability to correct GNE gene function and the safety of delivery of wild type GNE gene using a liposomal delivery vehicle. METHODS A single patient (subject #001) with severe HIBM treated by compassionate investigational new drug received four doses of GNE gene Lipoplex via intramuscular injection. GNE transgene expression, downstream induction of sialic acid, safety and muscle function were evaluated. RESULTS Significant durable improvement in locoregional skeletal muscle function was observed in the injected left extensor carpi radialis longus of #001 in correlation with GNE transgene upregulation and local induction of sialic acid. Other than transient low grade fever and pain at the injection site, no significant toxicity was observed. CONCLUSIONS Proof of principle for manufacturing of 'clinical grade' GNE gene Lipoplex, clinical safety and activity are demonstrated with GNE gene Lipoplex. Further assessment will involve intravenous administration and subsequent phase I trial involving additional but less severely afflicted HIBM patients.

Abstract
Background In Phase I evaluation of CT-2103 (paclitaxel poliglumex), prolongation of prothrombin time (PT) and activated thromboplastin time (aPTT) was observed, without clinical consequence, with doses 1.3–1.5 times higher than the current clinical dose of 175 mg/m2. This Phase I, open-label, nonrandomized pilot study was performed to study the effect of the standard dose regimen on blood coagulation. Methods Seven previously treated solid tumor patients received CT-2103 175 mg/m2 intravenously on day 1 of 21-day cycles for a mean of 5.4 cycles (median 4, range 2–14). Plasma samples were collected for cycle 1 predose and at hours 1, 24, 48, and 72 after the end of administration for drug levels, and for PT and aPTT assays. Results No coagulopathy-related adverse events were documented. Bleeding time remained normal in the six patients tested, with transient increases in PT and aPTT noted but resolving within 72 hours. Titration studies at 100 μg/mL of CT-2103 (corresponding to the standard clinical dose) prolonged PT and aPTT clotting times, produced a modest dose-dependent reduction of thrombin and factor Xa, and no significant changes in factors IXa, XIa, or XIIa. Two patients achieved stable disease for ≥10 cycles. Conclusion CT-2103 is associated with transient prolongation of PT and aPTT without clinical sequelae.

Abstract
RNA interference (RNAi) is a natural cellular regulatory process that inhibits gene expression by transcriptional, post-transcriptional and translational mechanisms. Synthetic approaches that emulate this process (small interfering RNA (siRNA), short hairpin RNA (shRNA)) have been shown to be similarly effective in this regard. We developed a novel 'bifunctional' RNAi strategy, which further optimizes target gene knockdown outcome. A bifunctional construct (bi-sh-STMN1) was generated against Stathmin1, a critical tubulin modulator that is overexpressed in human cancers. The bifunctional construct is postulated to concurrently repress the translation of the target mRNA (cleavage-independent, mRNA sequestration and degradation) and degrade (through RNase H-like cleavage) post-transcriptional mRNA through cleavage-dependent activities. Bi-sh-STMN1 showed enhanced potency and durability in parallel comparisons with conventional shRNA and siRNAs targeting the same sequence. Enhanced STMN1 protein knockdown by bi-sh-STMN1 was accompanied by target site cleavage at the mRNA level showed by the rapid amplification of complementary DNA ends (RACE) assay. Bi-sh-STMN1 also showed knockdown kinetics at the mRNA level consistent with its multieffector silencing mechanisms. The bifunctional shRNA is a highly effective and advantageous approach mediating RNAi at concentrations significantly lower than conventional shRNA or siRNA. These results support further evaluations.

Abstract
A phase I clinical trial was conducted to determine the clinical safety of Telomelysin, a human telomerase reverse transcriptase (hTERT) promoter driven modified oncolytic adenovirus, in patients with advanced solid tumors. A single intratumoral injection (IT) of Telomelysin was administered to three cohorts of patients (1 x 10(10), 1 x 10(11), 1 x 10(12) viral particles). Safety, response and pharmacodynamics were evaluated. Sixteen patients with a variety of solid tumors were enrolled. IT of Telomelysin was well tolerated at all dose levels. Common grade 1 and 2 toxicities included injection site reactions (pain, induration) and systemic reactions (fever, chills). hTERT expression was demonstrated at biopsy in 9 of 12 patients. Viral DNA was transiently detected in plasma in 13 of 16 patients. Viral DNA was detectable in four patients in plasma or sputum at day 7 and 14 post-treatment despite below detectable levels at 24 h, suggesting viral replication. One patient had a partial response of the injected malignant lesion. Seven patients fulfilled Response Evaluation Criteria in Solid Tumors (RECIST) definition for stable disease at day 56 after treatment. Telomelysin was well tolerated. Evidence of antitumor activity was suggested.

Abstract
RNA interference (RNAi) is a natural process through which expression of a targeted gene can be knocked down with high specificity and selectivity. Using available technology and bioinformatics investigators will soon be able to identify relevant bio molecular tumor network hubs as potential key targets for knockdown approaches. Methods of mediating the RNAi effect involve small interfering RNA (siRNA), short hairpin RNA (shRNA) and bi-functional shRNA. The simplicity of siRNA manufacturing and transient nature of the effect per dose are optimally suited for certain medical disorders (i.e. viral injections). However, using the endogenous processing machinery, optimized shRNA constructs allow for high potency and sustainable effects using low copy numbers resulting in less off-target effects, particularly if embedded in a miRNA scaffold. Bi-functional design may further enhance potency and safety of RNAi-based therapeutics. Remaining challenges include tumor selective delivery vehicles and more complete evaluation of the scope and scale of off-target effects. This review will compare siRNA, shRNA and bi-functional shRNA.

Abstract
Elevated Dicer and Drosha mRNA levels have been documented across a range of tumor types (including ovarian carcinoma) by a number of investigators without any demonstrable correlation with patient survival nor evidence of interference with shRNA processing. A recent publication by Merritt et al. (NEJM 359(25):2641-50, 2008) reporting their findings in patients with ovarian carcinoma reach opposite conclusions. Further study will be needed to resolve this issue.

Abstract
AIMS Currently available therapies do improve survival in advanced stage non-small cell lung cancer (NSCLC), but only to a limited degree. Talabostat mesilate (PT-100) is an orally available amino boronic dipeptide that specifically inhibits dipeptidyl peptidases (including fibroblast activation protein) and enhances an immune response. The aim of this study was to determine the efficacy and safety of talabostat in NSCLC patients. MATERIALS AND METHODS A phase II trial was conducted to evaluate talabostat in combination with docetaxel in patients with advanced NSCLC after failure of previous platinum-based chemotherapy. In total, 42 patients were enrolled. RESULTS Talabostat was well tolerated. Two patients achieved a partial response and one achieved a complete response. CONCLUSION There was no evidence that talabostat enhanced the clinical activity of docetaxel in patients with NSCLC.

Abstract
3548 Background: ARQ 197 is a selective, non-ATP competitive inhibitor of c-Met, a receptor tyrosine kinase implicated in tumor cell migration, invasion, and proliferation. Methods: This phase I dose escalation study enrolled patients (pts) with metastatic solid tumors to determine the drug's safety profile, maximum tolerated dose (MTD), recommended phase 2 dose (RP2D), pharmacokinetics (PK), and preliminary antitumor activity. Dose escalation followed an accelerated titration design and was modified to the traditional escalation design (3+3 pts) once grade 2 toxicity was observed. ARQ 197 was initially administered orally twice daily (BID) for 2 weeks followed by 1 week off and then modified to evaluate continuous BID dosing based on favorable safety data. Intra-patient dose-escalation was allowed in this study. Additional pts were enrolled and treated at the 360 mg bid continuous dose, which was determined to be the RP2D in another phase I clinical trial. Results: To date, 65 pts (38 male/27 female; median age 61; 9 colon/colorectal, 8 renal cell carcinoma/kidney, 6 ovarian, 6 sarcoma, 5 lung cancer and 31 others) have been treated at 11 dose levels (10 mg bid to 360 mg bid). All treated pts achieved plasma drug concentrations significantly above in vitro IC50 values. The most common drug-related adverse events (AEs) were fatigue (18.5%) and nausea (12.3%). One case each of the following drug-related serious AEs were reported in 4 pts: anemia, leukopenia, neutropenia, thrombocytopenia, dehydration, liver failure, abdominal pain, nausea, and vomiting. Three pts with neuroendocrine, prostate, or testicular cancer achieved a partial response (PR), 32 demonstrated stable disease (SD) and 13 progressed. The 3 PR pts were initially treated at 10, 40 or 90 mg BID respectively. Their doses were escalated to 50, 70, or 120 mg BID respectively after 18 to 33 weeks on treatment. An overall response rate of 6.3% and a disease control rate (CR+PR+SD) of 72.9% were demonstrated among 48 pts who are evaluable for efficacy. Conclusions: ARQ 197 has demonstrated a favorable safety profile up to the dose of 360 mg bid. Preliminary evidence of anti-cancer activity was observed. Final study data on drug safety, PK and efficacy will be presented. [Table: see text]

Abstract
e14507 Background: Pre-clinical studies demonstrate TM601 binding to glioblastoma, melanoma, and other tumor types in vitro and in vivo (human xenograft tumors in mice). Here we report imaging and safety data from a Phase I clinical trial in patients with recurrent metastatic somatic and/or cerebral solid tumors that received IV 131I-TM601. Methods: Patients received an IV imaging test dose of 10 mCi/0.2mg 131I-TM601. Subjects not showing tumor localization, received a second imaging test dose of 20 mC/0.4mg 131I-TM601. Subjects without localization at either dose were dropped from study; patients showing tumor localization without toxicity then received a 30 mCi/0.6mg 131I-TM601 IV injection. The primary objectives were to: 1) determine whole body localization and dosimetry, 2) estimate the maximum tolerated dose based on normal tissue dosimetry and 3) determine the acute toxicity of IV 131I-TM601. Results: A total of 44 evaluable patients received IV doses of 131I-TM601 without dose-limiting toxicity. 31/44 (70%) showed tumor specific uptake on follow-up gamma camera or SPECT imaging. Tumor-specific uptake was observed in patients with malignant glioma (7/8), metastatic melanoma (7/7), non-small cell lung cancer (3/4), colon cancer (6/7), pancreatic cancer (2/3), prostate cancer (2/2), breast cancer (1/4) and in one evaluable patient each with transitional cell carcinoma, pleomorphic xanthoastrocytoma and metastatic paraganglioma. Notably, all patients with metastatic cerebral disease showed tumor-specific uptake of systemically injected 131I-TM601. No uptake was seen in CNS lymphoma (n=1), ovarian (n=2), small cell lung (n=2), or medulllary thyroid cancers (n=1). Conclusions: Tumor-specific uptake of IV 131I-TM601 in primary and metastatic (including brain) solid tumors suggests that further dose escalation is warranted. Notably, IV injected 131I-TM601 crossed the blood brain barrier. Based on normal tissue dosimetry from this study, future clinical trials will evaluate safety and therapeutic efficacy in patients with recurrent glioma and metastatic melanoma at doses up to 100 mCi 131I-TM601 (maximum single dose).

Abstract
4629 Background: NTX-010 is a naturally occurring replication competent picornavirus with potent and selective tropism for human NE tumors, including small cell cancers and carcinoid. NTX-010 elicts rapid cytolysis in vitro and durable responses following IV dosing in multiple xenograft models. Methods: A first-in-human phase I study of IV NTX-010 was conducted across 5 log-increment dose cohorts from 107 vp/kg to 1011 vp/kg, in patients with NE cancers. Study endpoints included toxicity assessment, response assessment, evaluation of viral titers and clearance in blood, sputum, nasal swabs, urine, and stool, and assessment of neutralizing antibody (Ab) development. Results: 30 patients were treated (6 small cell, 24 carcinoid-type). All small cell patients were heavily pretreated (> third line) and received 107 vp/kg. In these patients, median PFS was 1.2 months and median OS was 4.1 months, including 1 long term (16 month +) survivor with prolonged SD after progressing through prior therapies. Carcinoid patients in cohorts 1–4 have 70% SD rate and median PFS of 5.4 months (95% CI 3.6 to NE); median OS has not been reached. Cohort 5, a 12 patient expansion cohort at 1011 vp/kg restricted to carcinoid, is still being monitored and shows promising antitumor activity including improvement in carcinoid syndrome symptoms, decline in 5HIAA and other serum markers, minor responses by CT scan, and an objective PET response (>50% decrease in SUV). There were no DLTs in any cohort. Evidence of intratumoral viral replication includes delayed kinetics in serum viral titer, post-infusion serum titers greater then the dose administered and positive immunohistochemistry and/or RT-PCR signal for viral antigens in tumor mass despite Ab production. Viral clearance was documented in all subjects and correlated temporally with development of antiviral Ab. Conclusions: NTX-010 is the first picornavirus to be evaluated as an anticancer therapeutic. A single IV dose of 1011 vp/kg of NTX-010 is safe, has predictable viral kinetics, and shows promising activity against NE tumors. Phase II testing of this novel agent either as a single agent or in combination with standard cytotoxic therapies is warranted. [Table: see text]
