e13071^ Background: Pancreatic cancer is the leading cause of cancer deaths worldwide with a very poor survival rate. No adequate therapy allows the patient to have a longer life of even 1 year. Methods: Dendritic cell(DC) based immunotherapy along with gemcitabine chemotherapy is planned to do phase I/II trial in 26 patients of advanced stage adenocarcinoma of pancreas. Inclusion criteria was defined as unresectable disease, ECOG performance status of not more than 2, Blood chemistry and hematocrit within normal range and of all age groups. Peripheral blood mononuclear cells are cultured in GM-CSF/IL-4 in RPMI. At 6th day of culture, the immature dendritic cells are exposed to antigens previously isolated from fresh excised tissue and further matured for 2 days. The cells along with medium are harvested and 1 million mature DC are infused IV by mixing them in 100 ml of dextrose normal saline with ondasnetron 4mg injection. Gemcitabine was given on day 1 and on day 8th and DC on day 15th. The cycle is repeated every month for 3 months followed by DC therapy alone at every 23 days interval till patient survives. The primary end point was overall survival and the secondary end point was improvement in quality quotient. Results: 6 patients survived for 24 months, 10 for 12 months and 3 for 6 months, with radiological improvement in only 4 patients with 25% reduction of disease. The quality quotient of 14 patients improved by second dose of dc therapy with improved appetite and decreased pain in abdomen including cheerfulness in 13 patients. Conclusions: Gemcitabine and DC immunotherapy is a good option for advanced stage pancreas cancer patients.

13029 Background: Proteasome inhibition blocks the chemotherapy-induced activation of NF-кB increasing chemosensitivity to anticancer agents due to increased apoptosis. NF-кB is frequently aberrantly activated in primary human carcinomas and over-expressed in aggressive breast cancer lines1 supporting the rationale for combining B with P. We designed a phase I-II and PD trial to determine the recommended dose (RD) of the B&P combination, to screen for antitumor activity in patients with potentially taxane-sensitive tumors, to search for drug-induced changes and to identify potential surrogate markers of drug activity and toxicity in peripheral blood mononuclear cells (PBMC). Methods: Eligibility included ECOG performance status < 2, neurotoxicity < 2 and adequate organ functions. Treatment was given Q21 days: B on days 1,4, 8 and 11 and P on days 1 and 8. PBMC for gene expression profiling have been collected on day 1 and 4 before and after therapy. RECIST for response was applied. Results: Twenty-nine patients (20 female, median age 60 yrs) were accrued and 25 are evaluable (breast cancer: 13, ovarian cancer: 7, prostate cancer 1, other 4) ; 16 pts were treated in 4 escalation levels and the RD defined respectively at 1.3 mg/m2/dose & 100 mg/m2/dose for B&P. Neurotoxicity was the main toxicity (G1 36%, G2 20% and 1 case G3) requiring treatment discontinuation in 2 pts at cy 6 & 7. Other toxicities (all grades) were nausea and vomiting (68%), diarrhea (56%, G3 12%), alopecia (52%), asthenia (36%, G2 4%), and myalgia (32%, G2 8%). Antitumor activity consisted of 3 PR in pts with ovarian cancer lasting respectively 14, 8+ and 16 wks; 2 PRs in pts with breast cancer (12+ wks,14+ wks) and 1 PR in a pt with prostate cancer. Conclusions: Thus far the regimen has acceptable toxicity with evidence of antitumor activity. The trial will continue until accrual of four additional patients as planned.

14635 Background: GVAX IT has been tested in phase I/ II and is currently being tested in phase III clinical trials of patients (pts) with androgen-independent prostate carcinoma (AIPC). Immunological and PSA responses have been described in men receiving GVAX IT. Preclinical studies have shown that antitumor immune responses induced by GVAX IT could be augmented further by making animals lymphopenic and reconstituting with lymphocytes prior to vaccination. A clinical trial was designed to study the effects of lymphopenic reconstitution in pts with AIPC. Methods: All pts had MC collection by leukapheresis pre-treatment. Study groups were as follows: Arm A - GVAX IT given every two weeks for 6 months; Arm B - Cyclophosphamide (350 mg/m2 IV on days 1–3), MC infusion on day 6, GVAX IT on day 7, then every 2 weeks for 6 months; Arm C - Cyclophosphamide (350 mg/m2 IV on days 1–3) and fludarabine (20 mg/m2 IV on days 1–3), MC infusion on day 6, GVAX IT on day 7, then every 2 weeks for 6 months. Results: Seven pts have been treated thus far and completed at least 2 GVAX IT treatments. Pts had ECOG performance status ≤ 1, castrate testosterone levels, ≤ 1 prior chemotherapy regimen and measurable or evaluable metastatic AIPC. Lymphopenia was induced in all pts enrolled in Arms B and C, with recovery of total granulocytes and lymphocytes within 4 weeks following treatment. Monitoring of humoral and cellular immunological responses is underway and shall be presented. Conclusions: GVAX IT and lymphopenic reconstitution is feasible in men with AIPC. Analysis of clinical and immune response is ongoing. Supported by DAMD grant PC020094 and generous support of Mr. Tom Denhart, the Chiles Foundation and the Murdock Trust. [Table: see text]

Solid Malignancies

e13518 Background: The mammalian target of rapamycin (mTOR) is a critical signaling pathway in many tumors including cancers of the breast and colon, glioblastoma multiforme, and hepatocellular carcinoma (HCC). Preclinical studies demonstrated the combination of BEZ235, a competitive dual phosphatidylinositide 3-kinase (PI3K)/mTOR inhibitor, and the mTOR inhibitor, everolimus led to greater regression of a carcinogen-induced HCC than treatment with higher doses of either drug alone. Based on this, we initiated a study of BEZ235 combined with everolimus in patients with advanced solid tumors. Methods: A single institution phase Ib dose-escalation study. Patients with advanced solid malignancies, no available standard of care treatment option, and ECOG performance status 0-2 were eligible. Prior treatment with PI3K inhibitors was not allowed. Sequential cohorts of 3-6 patients were treated. The starting dose was everolimus 2.5 mg and BEZ235 200 mg daily in an oral sachet formulation. Cohort 2 received everolimus 2.5 mg and BEZ235 400 mg daily. Pharmacokinetic and pharmacodynamic studies were performed during the first cycle. The phosphorylation of specific downstream effectors of the mTOR pathway was assessed in peripheral blood mononuclear cells (PBMC). Results: Eleven patients, median age 58 (36-73 years) were treated. Tumors included non-small cell lung cancer, colon cancer, and glioblastoma, hepatocellular carcinoma, pancreatic cancer, esophageal cancer, adenoid cystic carcinoma of the larynx, and appendiceal carcinoma. Four patients were treated on cohort 1. None experienced dose-limiting toxicity. Seven patients were treated on the second dose cohort. One patient withdrew necessitating replacement and another developed grade 3 stomatitis from herpes virus requiring cohort expansion. The most common adverse events were thrombocytopenia, lymphopenia, transaminitis, diarrhea, nausea and fatigue. No tumor responses were noted. PBMC showed a decrease in 4E-BP1S65 phosphorylation on day 28 in 2 of 3 patients in cohort 1. Conclusions: The combination of BEZ235 and everolimus was well tolerated at these doses. The trial remains open to accrual. Clinical trial information: NCT01508104.

Background/Objective: With the increasing interest in natural products, a phase I openlabel study of OMN54 (Aneustat™) in patients with advanced malignancies was initiated to determine toxicity, maximum tolerated dose (MTD), dose limiting toxicities (DLT), and pharmacokinetics (PK). OMN54 is a multitargeted agent, combining three Chinese botanicals; Ganoderma lucidium, Salvia miltiorrhiza and Scutellaria barbata. Methods: Eligible patients (pts) were >18 years of age with advanced solid tumors, able to swallow oral capsules, ECOG performance status < 2, measurable disease as defined by RECIST 1.1 and adequate organ function. Results: Twenty-two patients were enrolled in 6 dose levels, 2 with daily dosing and 4 with twicedaily dosing ranging from 1 to 5 grams daily. All were evaluated for toxicity and 20 for response. No treatment-related dose-limiting toxicities (DLTs) were reported and the recommended phase II dose (RP2D) was determined to be 2.5 g twice daily. Seven adverse events in 5 patients were reported as possibly drug-related; 6 were GI toxicity and 1 was a skin disorder. All were grade 1 except one grade 2 vomiting. No RECIST responses were seen. Six pts were treated with > 2 cycles; one for 8 cycles. Four patients had reductions in TGF –β and EGF, exploratory biomarkers possibly suggestive of a drug effect. Plasma half-lives of 1 -2 hours were noted for all parent drug chemical markers with no accumulation over time. Conclusion: OMN54 was well tolerated, with no DLTs observed. Further studies at the RP2D will assess the biological activity.

Antigenic Properties

Lack of efficacious vaccines against Mycobacterium tuberculosis (MTB) infection is a limiting factor in the prevention and control of tuberculosis (TB), the leading cause of death from an infectious agent. Improvement or replacement of the BCG vaccine with one that reliably protects all age-groups is urgent. Concerns exist that antigens currently being evaluated are too homogeneous. To identify new protective antigens, we screened 1781 proteins from a high-throughput proteome-wide protein purification study for antigenic activity. Forty-nine antigens (34 previously unreported) induced antigen-specific IFN-γ release from peripheral blood mononuclear cells (PBMCs) derived from 4452 TB and suspected TB patients and 167 healthy donors. Three (Rv1485, Rv1705c and Rv1802) of the 20 antigens evaluated in a BALB/c mouse challenge model showed protective efficacy, reducing lung CFU counts by 66.2%, 75.8%, and 60%, respectively. Evaluation of IgG2a:IgG1 ratios and cytokine release indicated that Rv1485 and Rv1705c induce a protective Th1 immune response. Epitope analysis of PE/PPE protein Rv1705c, the strongest candidate, identified a dominant epitope in its extreme N-terminal domain accounting for 90% of its immune response. Systematic pre-clinical assessment of antigens Rv1485 and Rv1705c is warranted.

Purpose Gemcitabine plus nanoparticle albumin-bound (NAB) paclitaxel (GA) significantly improved survival compared with gemcitabine alone in patients with metastatic pancreatic ductal adenocarcinoma (PDAC) and a Karnofsky performance status (PS) of 70% or greater. Because of the low number of patients with reduced PS, the efficacy of this regimen in fragile patients remains unclear. This study aimed to evaluate the efficacy and tolerability of different GA dosing regimens in patients with a poor PS. Patients and Methods In the phase I part of this study, patients were randomly assigned to one of the following four parallel GA treatment arms (six patients per arm): a biweekly schedule of NAB-paclitaxel (150 mg/m2 [arm A] or 125 mg/m2 [arm C]) plus gemcitabine 1,000 mg/m2 or a standard schedule of 3 weeks on and 1 week off of NAB-paclitaxel (100 mg/m2 [arm B] or 125 mg/m2 [arm D]) plus gemcitabine 1,000 mg/m2. The two regimens with the better tolerability profile on the basis of predefined criteria were evaluated in the phase II part of the study, the primary end point of which was 6-month actuarial survival. Results Arms B and D were selected for the phase II part of the study. A total of 221 patients (111 patients in arm B and 110 patients in arm D) were enrolled. Baseline characteristics including median age (71 and 68 years in arms B and D, respectively), sex (51% and 55% men in arms B and D, respectively), and metastatic disease (88% and 84% in arms B and D, respectively) were comparable between arms. The most frequent grade 3 or 4 toxicities in arms B and D were anemia (12% and 7%, respectively), neutropenia (32% and 30%, respectively), thrombocytopenia (7% and 11%, respectively), asthenia (14% and 16%, respectively), and neurotoxicity (11% and 16%, respectively). In arms B and D, there were no significant differences in response rate (24% and 28%, respectively), median progression-free survival (5.7 and 6.7 months, respectively), and 6-month overall survival (63% and 69%, respectively). Conclusion NAB-paclitaxel administered at either 100 and 125 mg/m2 in combination with gemcitabine on days 1, 8, and 15 every 28 days is well tolerated and results in acceptable safety and efficacy in patients with metastatic pancreatic ductal adenocarcinoma and a poor PS.

Breast Cancer (BC) is the leading cause of death in women, worldwide. The Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of BC can be studied using HRV measures. The main purpose of this chapter is to give an insight to clinicians via HRV measures with respect to age to make them understand the PS of patients. Data from 114 BC patients was segregated into two age groups, G1 (20 to 40 years) and G2 (41 to 75 years). The 5-minute electrocardiogram of the subjects was taken and HRV measures were extracted. One-way ANOVA with Posthoc Tukeys' HSD test was done. Triangular Index, Ratio of standard deviation of poincare plot perpendicular to the line of identity to the standard deviation along line of identity, Detrended Fluctuation Analysis descriptors, Approximate Entropy, Sample Entropy and Correlation Dimension significantly decreased from ECOG0 to 4 and from G1 to G2. The sympathetic activity increased with vagal withdrawal as age advanced.

Abstract Background Subcutaneous (SC) azacitidine prolongs overall survival in subjects with higher-risk MDS (Fenaux, JCO, 2009). Previous Phase I and II studies have shown extended oral azacitidine dosing schedules to be safe and effective in subjects with IPSS-defined lower-risk MDS (Garcia-Manero et al, ASH 2010 and ASH 2012). Objective To assess the efficacy and safety of extended oral azacitidine dosing schedules in subjects with WHO-defined RAEB-1 or RAEB-2 MDS. Methods The subset of subjects with WHO-defined RAEB-1 or RAEB-2 MDS from two ongoing Phase I/II studies was included in this ad hoc analysis. Subjects received oral azacitidine 300mg QD or 200mg BID for 14 or 21 days of repeated 28-day cycles. For purposes of this analysis, subject data were analyzed collectively. Hematologic responses were defined by International Working Group (IWG) 2006 criteria. Overall Response was calculated as any response of complete or partial remission (CR or PR), RBC or platelet transfusion independence (TI), and/or any hematologic improvement (HI). Marrow complete remission (mCR) was not included in Overall Response. Serious treatment-emergent adverse events (STEAEs) that occurred in 2 or more subjects are reported. Results Of 23 subjects in all, 20 received 300mg QD oral azacitidine x 14 or 21 days/28-day cycle and 3 received oral azacitidine 200mg BID x 14 days/28-day cycle. Subjects had median age of 71 (range: 36 - 90) years and were predominantly male (61%). Fourteen subjects (61%) had a diagnosis of RAEB-1 and 9 (39%) had RAEB-2, median time from diagnosis was 2.1 (0.1 - 33.2) months, and ECOG performance status scores were 0 (n=4, 17%), 1 (n=15, 65%), or 2 (n=4, 17%). Five subjects had received prior MDS treatments (azacitidine injection; erythropoiesis stimulating agent [ESA]; thalidomide; azacitidine injection and decitabine; G-CSF, anti-thymocyte globulin, methylprednisolone, cyclosporine, and ESA). Median number of oral azacitidine treatment cycles was 3 (1 - 29). Overall Response was achieved by 11/22 subjects (50%) (Table). Four subjects achieved mCR only and are not included in the Overall Response category. RBC TI was achieved by 5/12 subjects (42%) and platelet TI was achieved by 2/5 subjects (40%). Two subjects were able to consolidate remission and proceed to allogeneic stem cell transplant and 1 subject progressed to AML on-study. Oral azacitidine was generally well tolerated. Three subjects discontinued treatment due to an AE. STEAEs were consistent with the known safety profile of SC azacitidine. Of 8 subjects who had an STEAE of febrile neutropenia, pneumonia, and/or septic shock, 3 were severely neutropenic (ANC <0.5 x 109/L) at baseline. Other STEAEs were diarrhea, nausea, and vomiting (n=2 subjects each). Conclusions This analysis in subjects with RAEB-1 and RAEB-2 is the first to assess extended oral azacitidine dosing schedules in higher-risk MDS. One-half of treated subjects achieved a hematologic response to oral azacitidine, which is easy to administer and was generally well-tolerated. Two Phase III studies of extended oral azacitidine dosing (in lower-risk MDS and as maintenance therapy in older patients with AML) are ongoing. Results of these large studies will better elucidate the use of extended oral azacitidine dosing schedules in treating hematologic malignancies. Disclosures: Gore: Celgene Corporation: Consultancy.
