TPS2604 Background: EphA2 is a member of the largest subfamily of receptor tyrosine kinases, with over 14 receptors and 8 ligands. EphA2 overexpression is common in many human cancers, including lung, breast, prostate, colorectal, pancreatic, melanoma, esophageal and endometrial cancers. EphA2 can function as an oncoprotein when introduced into cells with low expression. In addition, downregulation of constitutive expression reduces tumorigenicity in breast, endometrial, ovarian and pancreatic cancers in vitro and in vivo models. EphA2 is a desirable target because of its selective expression in cancer (vs. adult normal tissue), and its important role in promoting tumor growth and metastasis. It has kinase-dependent and independent functions, making it an ideal target for RNAi-based targeting. We have previously reported that EphA2 siRNA incorporated in DOPC nanoliposomes (EPHARNA) was highly effective in reducing EphA2 protein levels after a single dose. In addition, three weeks of treatment with EPHARNA (150 μg/kg twice weekly) in an orthotopic mouse model of ovarian cancer (HeyA8 or SKOV3ip1) significantly reduced tumor growth compared with non-silencing siRNA, and demonstrated synergistic anti-tumor activity when combined with conventional chemotherapy. EPHARNA underwent GLP development in 2 animal models (murine and primate) at M.D. Anderson to support the IND (#72924). The first-in-human trial (NCT01591356) is ongoing and recruiting study subjects. Methods: Adult Patients > 18 years of age with histologic proof of advanced recurrent solid tumors, who are not candidates for known regimens or protocol treatments of higher efficacy or priority. All patients (dose escalation and dose expansion phases) must be willing to undergo pre- and post-treatment biopsies. For dose expansion phase, patients must have EphA2 overexpression by IHC evaluation. Enrollment is ongoing for the dose escalation with the plan for dose expansion. A total of 16 patients have been enrolled and treated in the dose escalation phase. Clinical trial information: NCT01591356.

TPS3105 Background: Imprime PGG (Imprime) is a Pathogen- Associated Molecular Pattern that enhances innate immune cell killing, counteracts immune suppression and triggers activation and maturation of antigen presenting cells. Imprime’s ability to trigger a coordinated innate and adaptive immune response is critical for enhancing the efficacy of CPIs in several pre-clinical tumor models. We are now exploring the combination of PGG beta-glucan and Pembrolizumab, a humanized mAb against programmed death receptor-1 (PD-1) in the clinic. In previous trials, Pembro yielded a 33% ORR and 23 mo mOS in 655 pts with advanced MEL and an 18.5% ORR and 11.2 mo mOS in 27 evaluable pts with metastatic/recurrent TNBC (Ribas et al., 2016; Nanda et al., 2016). Pre-treatment levels of anti-beta glucan antibodies (ABA) are correlated with pt response to Imprime. Methods: This Phase 2 study is enrolling ABA positive pts with advanced MEL following progression on treatment with a CPI or metastatic TNBC failing front-line chemotherapy. The study is a Simon optimal 2-stage design with sample size of 12 pts of each tumor type in Stage 1. If response and AE criteria (≤ 4 [or ≤ 33%] pts with grade 3/4 in Cycle 1) for each tumor type are met, an additional 17 pts with MEL and 30 pts with TNBC will be enrolled in Stage 2. Primary endpoints of the study are ORR (based on RECIST 1.1) and safety. Secondary endpoints include TTR, CRR, DoR, PFS, and OS. PK data will be profiled. Exploratory endpoints include ORR and PFS based on irRECIST, analysis of an ABA biomarker, immune cell activation markers, and changes in the tumor immune microenvironment. Screening and enrollment are underway in the US. Biothera Pharmaceuticals, Inc. is sponsoring the trial (ClinicalTrials.gov NCT02981303) under a collaborative agreement with Merck. Clinical trial information: NCT02981303.

TPS3107 Background: CX-072 is a novel Probody therapeutic (PbTx) targeting PD-L1. PbTxs are fully recombinant antibody prodrugs designed to be converted to active antibodies by tumor-associated proteases that are highly expressed malignant tissue; the PbTx remains largely inactive in normal tissues. In pre-clinical tumor models, a PD-L1-directed PbTx provided comparable anti-tumor efficacy to its parental anti-PD-L1 antibody, but displayed reduced auto-immunity in a model of Type 1 diabetes. Based on these pre-clinical data, CX-072 has the potential to enable combination therapies that are otherwise poorly tolerated. This Phase 1/2 study (PROCLAIM-001 (PRObody CLinical Assessment In Man) assesses the tolerability and antitumor activity of CX-072 in humans with an emphasis on immune-related adverse events, particularly in combinations. CX-072 will be administered as monotherapy (Part A), in combination with 2 schedules of ipilimumab (Parts B1 and B2) and in combination with vemurafenib (Part C). The expansion cohort (Part D) will include CX-072 monotherapy in PD-L1 responsive tumor types. Methods: Key eligibility criteria are as follows: Parts A and B1: checkpoint inhibitor-naive patients with advanced, refractory solid tumor or lymphoma (unmeasurable disease allowed) for whom approved PD agents are not available. Part B2: advanced, refractory solid tumors or lymphomas with measurable disease who have progressed on a previous treatment with a PD-(L)1 inhibitor, but did not discontinue due to toxicity. Part C: checkpoint inhibitor, BRAF-inhibitor and MEK-inhibitor-naïve metastatic V600E BRAF-mutated melanoma. Patients without an active autoimmune disease, ongoing infection, and ECOG PS 0-1 may be eligible to participate in the study. Dose escalation follows the 3+3 design in all arms. Ipilimumab (Parts B1 and B2) is dosed at the approved 3 mg/kg every 3 weeks x 4. The dose of vemurafenib (Part C) is 960 mg/kg twice daily. Exploratory biomarkers are used to characterize tumor protease activity, inflammatory changes within the tumor, and CX-072 activation in tumor versus peripheral blood. Clinical trial information: NCT03013491.

TPS3109 Background: The cell surface protein CD47 is expressed or over-expressed on many tumor types. CD47 binds to signal regulatory protein alpha (SIRPα) on macrophages resulting in a “don’t eat me” signal that blocks host cell phagocytosis of the tumor cells, thus allowing them to escape removal by the innate immune system. Recent data indicate that anti-CD47 antibodies also contribute to an effective anti-tumor T cell response in immune-competent mice. Therefore, anti-CD47 antibodies are a new class of immune checkpoint inhibitors that modulate both the innate and adaptive immune systems. Ti-061 is a novel IgG4 humanized monoclonal antibody that specifically binds to CD47 with Kd values range from 100 – 500 pM. Ti-061 exhibits cross-species binding to cynomolgus monkey, mouse and rat CD47, enabling efficacy and toxicity testing across species. Ti-061 binds to CD47 on RBCs; however, it does not cause agglutination of RBCs in vitro from any of the species tested. Ti-061 exhibits anti-tumor activity in several in vivo mouse tumor models. This ongoing Phase 1-2 study will assess the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of Ti-061 alone and in combination with other anti-cancer agents in patients with advanced malignancies. Methods: Part A is an open-label, dose-escalation study of Ti-061 administered as a weekly 1-hour IV infusion at doses ranging from 1 to 20 mg/kg. Once the MTD/RP2D or “active dose” is determined, patients with specific solid tumors and high CD47 expression will be enrolled in 4 or more expansion cohorts. Up to 160 patients with histologically confirmed solid tumors, ECOG PS 0-1, adequate blood counts (Hb≥ 10 g/dL), organ function, and archival or fresh tumor tissue will be enrolled in Part A, and will be treated until disease progression, unacceptable toxicity, or withdrawal. Primary endpoint is safety, which will be assessed using NCI-CTCAE v4.03. Secondary endpoints include PK, PD, objective response rate (ORR) and progression-free survival (PFS), which will be assessed using RECIST v1.1. The results of this study will support further development of Ti-061 in combination with checkpoint inhibitors (Part B) and other anti-cancer agents.

TPS3112 Background: Bispecific antibodies to facilitate T-cell directed cytotoxicity (TDCC) is a proven therapy strategy in cancer. ERY974 is a humanized IgG4 bispecific antibody designed to simultaneously bind to cytotoxic T-cell CD3 receptors and GPC3 (a glycoprotein expressed on cell surface of several tumors) to elicit T-cell activation and TDCC. The objectives of this multi-country, phase 1 study of ERY974 is to determine the maximum tolerated dose (MTD) and to perform a preliminary assessment of anti-tumor activity in patients with solid tumors expressing GPC3. Methods: ERY974 is dosed IV weekly. All patients receive premedication with dexamethasone (DEX) prior to 1st and 2nd ERY974 dose. DE uses an accelerated titration design (ATD), then a modified continual reassessment method (mCRM) described by one-parameter logistic model, to determine MTD, where DLT occurrence rate is 0.25. Combining ATD and mCRM is to permit rapid dose escalation whilst minimizing patient numbers exposed to sub-therapeutic doses, and to accurately determine MTD. Once grade 2 (G2) cytokine release syndrome (CRS) is observed, DEX is increased. If ≥G2 CRS is again observed, then at all subsequent doses the 1st dose of ERY974 is fixed at the last dose level when < G2 CRS was not seen, DE proceeds with the 2nd dose. ATD commences with n = 1, increasing to n = 3 once drug-related ≥G2 toxicity is seen. mCRM starts after 1st dose limiting toxicity (DLT), with the modifications of at least 3 patients required to dose escalate and up to 1.5x increment to minimize risk of toxicity. CE has 3 arms: GPC3+ gastric/gastroesophageal junction adenocarcinoma; GPC3+ squamous esophageal cancer; and other GPC3+ tumors. A 2-stage design is used to allow CE to stop early for futility. Subjects are adults with histologically confirmed, measurable malignant solid tumors and/or metastatic disease not amenable to standard therapy, and life expectancy ≥3 months. Patients with > 1cm or > 1 brain metastasis, current/previous interstitial lung disease, and acute/chronic infection are excluded. 3 cohorts have been completed without DLT. Cohort 4 began in January 2017. Clinical trial information: NCT02748837.

TPS3114 Background: Mutation-derived tumor antigens (MTAs) arise as a direct result of somatic variations, including nucleotide substitutions, insertions, and deletions that occur during carcinogenesis. These somatic variations can be characterized via genetic sequencing and used to identify MTAs. We propose a platform for a fully-personalized MTA-based vaccine in the adjuvant treatment of solid tumors. Methods: This clinical trial is a single-arm, open label, proof-of-concept phase I study designed to test the safety and immunogenicity of the Personalized Genomic Vaccine 001 (PGV001). The single-center study will enroll 20 eligible subjects with histological diagnosis of the following tumor types: (a) head and neck squamous cell cancer, (b) non-small cell lung cancer, (c) ductal or lobular breast cancer, (d) serous carcinoma of the ovary, uterine adnexa, (e) urothelial carcinoma of renal pelvis or bladder, (f) cutaneous squamous cell cancer. Subjects must have no measurable disease at time of first vaccine administration, and 5-year disease recurrence risk of > 30%. Patients will receive 10 doses of PGV001 as well as 10 doses of poly-ICLC (toll-like receptor-3 agonist, vaccine adjuvant), administered 1 day after PGV001 vaccination. Toxicity (endpoint 1) will be defined by Common Terminology Criteria for Adverse Events v5.0. Blood samples will be collected at various time points for immune response monitoring of MTA-specific humoral and cellular immune responses. For each patient, immunogenicity (endpoint 2) will be defined as an epitope-specific T cell response, detectable in peripheral blood samples after PGV001 vaccination. The change in the frequency of vaccine-induced epitope-specific T lymphocyte populations post-vaccination relative to baseline will be determined using mixed effects linear regression modeling. Conclusions: Our clinical trial will test for the first time the safety and immunogenicity of PGV001 in patients with multiple solid cancers. The information learned from this clinical trial will instruct the next generation of MTA-based vaccines, future development of immunotherapeutic approaches and rational combinations. Clinical trial information: NCT02721043.

TPS3633 Background: For patients with initially unresectable colorectal liver metastases (CRLM) with good clinical response to chemotherapy, the presence of disappearing liver metastases (DLMs) diagnosed by CT is a major independent prognostic factor. DW-MRI as well as contrast enhanced (CE)-MRI is recommended to detect and characterize CRLM. However, the correlation between radiological and pathological complete response has not been fully investigated using these latest imaging and pathology techniques. Our main aim is to demonstrate the added value of DW-MRI, CE-MRI to that of CT alone to provide precise assessment of the viability of DLMs. In addition, we aim to optimize the therapeutic management of CRLM patients. No prospective study has been conducted to determine the predictive value of DW-MRI combined with CE-MRI in confirming sites of DLMs and assessing their true status. Methods: This is the first collaborative study between EORTC, ESSO and JCOG with an integrated quality assurance program for imaging, surgery and pathology. Patients with unresectable CRLM will receive standard systemic chemotherapy and liver resection if resectable. Both CT and MRI (DW-MRI, CE-MRI and T1/T2) will be used to identify confirmed DLMs (cDLMs). cDLMs will be either resected or, if resection is not possible, followed-up without resection until 2 years after surgery to evaluate the true status of the cDLMs. The primary endpoint is negative predictive value (NPV) of DW-MRI, CE-MRI, T1/T2 and CT in confirming the status of cDLMs using as reference either the histopathological complete response or the absence of a local recurrence at the site of cDLMs during the follow up period of 2 years. The study aims at excluding a NPV≤0.85 and is powered under the alternative that the NPV≥0.95. The planned sample size is 92 evaluable (resected or left behind) cDLMs, with a 1-sided alpha of 5% and a power of 90% adjusting for within-patient correlation between cDLMs of 0.2 and an average number of 2 cDLMs per patient. Approximately 400 patients will be registered from European, Japanese and US sites over 3 years. As of February 2017, 2 patients have been enrolled. Clinical trial information: NCT02781935.

TPS4144 Background: No standard adjuvant treatment has been established for patients with curatively resected biliary tract cancer (BTC). S-1, which is one of the oral fluoropyrimidine derivatives, showed promising efficacy with a mild toxicity profiles in patients with advanced BTC, and the survival benefit of adjuvant S-1 therapy has been demonstrated in patients with resected gastric cancer and pancreatic cancer. The aim of this open-label, multicenter, randomized phase III trial is to assess whether adjuvant S-1 would prolong the overall survival in patients with resected BTC. Methods: The main eligibility criteria are as follows: 1) curatively resected carcinoma of the extrahepatic bile duct, gallbladder or ampulla of Vater (T2-4, N0, M0 or T1-4, N1, M0), or carcinoma of the intrahepatic bile duct (T1-4, N0-1, M0) (7th UICC classification), 2) histologically confirmed adeno (squamous) carcinoma, 3) R0 or R1 residual disease, 4) age 20 to 80 years, 5) ECOG performance status 0 or 1, 6) no prior chemotherapy or radiotherapy, 7) adequate organ functions, 8) written informed consent. Patients are randomly assigned to the surgery alone arm (arm A) or the adjuvant S-1 arm (arm B) by the minimization method for balancing institution, primary site of cancer and lymph node metastasis between the arms. Patients in arm A do not receive any anti-cancer treatment, while patients in arm B receive 4 cycles of oral S-1 chemotherapy at the dose of 40 mg/m2 twice daily for 4 weeks followed by 2 weeks of rest. The primary endpoint is overall survival, while the secondary endpoints are relapse-free survival, incidence of (serious) adverse events, and proportion of treatment completion. We assumed a 3-year survival in arm A of 47% and a 10% increase in the 3-year survival in arm B. The sample size was calculated as a total of 350, with a one-side alpha of 5% and power of 70%; planned accrual period is 4 years, and follow-up period, 3 years. Primary analysis will be conducted at 3 years and updated analysis will be conducted at 5 years after closing of accrual. As of Jan 31, 2016, a total of 285 patients have already been enrolled in this trial from Sep 2013. Clinical trial information: UMIN000011688.

TPS4148 Background: Cancer stem cells are considered to be fundamentally important for resistance to therapy, recurrence and metastasis. Napabucasin is a first-in-class cancer stemness inhibitor identified by its ability to inhibit STAT3-driven gene transcription and spherogenesis of cancer stem cells (Li et al, PNAS 112(6):1839, 2015). Preclinical studies suggest that napabucasin sensitizes heterogeneous cancer cells to chemotherapeutic agents, including nab-PTX and gem. Encouraging anticancer activity in mPDAC was observed in a phase Ib (El-Rayes et al, ASCO 2016) study of 37 pts, reporting 93% (28/30) disease control rate (DCR) and 50% (15/30) overall response rate (ORR), with 1 complete and 14 partial responses and prolonged disease control ( > 24 wks) in 57% (17/30) of pts who have had a RECIST evaluation. On the basis of these data, a phase III trial is being conducted in North America, Europe, Australia and Asia. Methods: This study (ClinicalTrials.gov NCT02993731) will assess the efficacy of napabucasin+nab-PTX+gem vs nab-PTX+gem in pts with mPDAC (n = 1132). Pts must have been diagnosed with mPDAC < 6 weeks prior to randomization and not have received treatment for metastatic disease. Pts are randomized in a 1:1 ratio to receive napabucasin 240 mg PO twice daily continuously plus nab-PTX+gem IV weekly for 3 out every 4 weeks, or nab-PTX+gem IV weekly for 3 out every 4 weeks. Pts will be stratified by geography, performance status and presence of liver metastases. Treatment will continue until disease progression, death, intolerability or patient/investigator decision to stop. Primary endpoint is overall survival (OS) in the general study population (HR 0.80 for OS improvement from 8.5 to 10.63 months); secondary endpoints include progression free survival (PFS), OS and PFS in the biomarker positive sub-population, ORR and DCR, safety and quality of life. In addition, blood and tumor archival tissue will be assessed for pharmacokinetic and biomarker analyses. Global enrollment is underway. Clinical trial information: NCT02993731.
