TPS4132 Background: Pts with adv G/GEJ cancer have an OS of ≈ 1 y, indicating an unmet medical need for new first-line treatments (Tx). Expression of the PD-1 ligands PD-L1/PD-L2 is observed in up to 40% of pts with G/GEJ cancer and is associated with poor prognosis. In a phase 3 study of the PD-1 inhibitor nivo vs placebo in pts with adv CTX-refractory (CTX-R; ≥ 2 lines) G/GEJ cancer, nivo reduced the risk of death by 37% (HR, 0.63; P < 0.0001) and increased the OS rate at 12 mo (27% vs 11%; Kang YK, et al. J Clin Oncol. 2017;35 (suppl 4S) [abstract 2]). In a phase 1/2 study in pts with CTX-R G/GEJ/esophageal cancer (79% ≥ 2 prior Tx lines), nivo 1 mg/kg + ipi 3 mg/kg had a manageable safety profile and resulted in 26% ORR (44% ORR in pts with PD-L1+ tumors), a median OS of 6.9 mo, and a 34% OS rate at 12 mo (Janjigian Y, et al. ASCO, 2016 [abstract 4010]). In the phase 1 CheckMate 012 trial, nivo + CTX had clinical activity and manageable safety in pts with NSCLC (Rizvi NA, et al. J Clin Oncol. 2016;34:2969-2979). These positive results support investigation of nivo, nivo + ipi, and nivo + CTX in earlier lines of Tx for G/GEJ cancer. The open-label, phase 3 CheckMate 649 trial will evaluate nivo + ipi and nivo + CTX vs CTX alone as first-line Tx for pts with adv G/GEJ cancer (NCT02872116). Methods: 1266 pts aged ≥ 18 y with untreated, inoperable adv/metastatic G/GEJ cancer (histologically confirmed adenocarcinoma) regardless of PD-L1 status will be randomized to receive either nivo + ipi, nivo + CTX (capecitabine/oxaliplatin [XELOX] or fluorouracil/leucovorin/oxaliplatin [FOLFOX]), or investigator choice of XELOX or FOLFOX. Tumor tissue for determination of PD-L1 status (Dako assay) must be provided from ≤ 6 mo before study Tx. No prior systemic Tx, including HER2 inhibitors, are allowed. Pts with known HER2+ status, suspected autoimmune disease, grade > 1 peripheral neuropathy, or active infection are excluded. Primary endpoint is OS in pts with PD-L1+ (≥ 1%) tumors. Other endpoints include OS in all pts; PFS and time to symptom deterioration in all pts and in pts with PD-L1+ tumors; and safety. Clinical trial information: NCT02872116.

TPS4134 Background: In Japan, while post-operative adjuvant chemotherapy with S-1 or capecitabine plus oxaliplatin is standard care for pStage II/III gastric cancer after curative resection with D2 lymph node dissection, the clinical outcomes of pStage III patients are not satisfactory. In Europe, neoadjuvant chemotherapy (NAC) followed by gastrectomy is standard. The Japan Clinical Oncology Group (JCOG) has conducted several phase II trials of NAC, and deemed NAC as one of the most promising treatment strategies for gastric cancer with lymph node metastasis (Stage III). However, no established criteria exists for diagnosis of lymph node metastasis. JCOG1302A which was a cross-sectional study evaluating the accuracy of preoperative staging by imaging, showed that cT3-4N1-3M0 (positive lymph node was defined as that with a long axis diameter ≥ 10 mm or short axis diameter ≥ 8 mm) included just 6.5% overdiagnosed pStage I patients and accounted for 52.6% of all pStage III patients. Methods: JCOG1509 (UMIN000024065) is designed as a randomized phase III study to confirm the survival superiority of addition of NAC to standard treatment for patients with cT3-4N1-3M0 gastric cancer. In the standard arm, a gastrectomy with D2 lymphadenectomy is performed followed by adjuvant chemotherapy with oral S-1 for 1 year. In the experimental arm, combination of an infusion of oxaliplatin (130 mg/m2/day, day 1) and oral S-1 (80 mg/m2/day, days 1–14) is repeated every 3 weeks for 3 courses before gastrectomy, followed by surgery and adjuvant chemotherapy with S-1 for 1 year. The primary endpoint is overall survival. The planned sample size is 470 in total with a 1-sided alpha of 5%, a power of 80%, expecting a 10% increase in the 5-year OS (60% vs 70%). Patients will be enrolled from 58 Japanese institutions over 3.5 years. The study was activated in September 2016 and, as of January 2017, 18 patients were enrolled for the study. Clinical trial information: UMIN000024065.

TPS4154 Background: Optimal treatment strategy beyond systemic chemotherapy for LAPC remains undefined. SBRT improves local control, but distant metastasis free survival (DMFS) is only 7.7 months. Checkpoint inhibitors are poor monotherapies in pancreas cancer, but may be primed by SBRT via absocopal effect and GVAX, which induces novel lymphoid infiltrates and increased effector T-cells in tumor microenvironment. Methods: This is a single-arm, single-institution, open-label study for pts with LAPC. Eligibility: surgically unresectable LAPC, predominant adenocarcinoma at diagnosis, with ECOG 0-1, who remain metastases free after 4-8 cycles of FOLFIRINOX or gemcitabine/abraxane based-chemotherapy. Exclusion: those off chemotherapy > 49 days prior to study treatment, prior immunotherapy, active immunosuppressive use, autoimmune disease, HIV, HBV, or HCV infection, and non-oncology vaccines within 28 days of study treatment. Pts receive cyclophosphamide (200mg/m2 IV) and pembrolizumab (200mg IV) on day 1, followed by GVAX (six intradermal injections) on day 2 every three weeks for two cycles, with cycle 2 initiating concurrently with five days of SBRT. If non-metastatic, pts undergo surgical resection, nano-knife, or EUS guided biopsy (if non-surgical). Pts receive two further cycles of chemotherapy, and if remain free of metastases, receive q3 week cyclophosphamide, pembrolizumab, and GVAX for six cycles, then are monitored for two years. The primary endpoint is DMFS. Secondary endpoints include overall survival, surgical resectability, pathologic response, quality of life, and toxicity. Exploratory objectives of peripheral antigen specific t-cell responses, and changes in immune parameters of tumor microenvironment. 11 of 54 pts have been enrolled since July 2016. Clinical trial information: NCT02648282.

TPS4601 Background: In the cytokine era cytoreductive nephrectomy (CN) has been shown to increase survival in patients (pts) with metastatic renal cell carcinoma (mRCC). Efficacy of tyrosine kinase inhibitors (TKIs), including first-line sunitinib and pazopanib has been demonstrated. It is unclear if similar survival benefit could be achieved without CN with TKIs since most of pts enrolled into phase III trials had undergone CN. Methods: A total of 270 mRCC pts will be randomized to receiveCN followed by TKIs vs upfront TKIs without CN. Patients will receive pazopanib 800 mg orally daily or sunitinib 50 mg daily, 4 weeks on/ 2 weeks off. The choice of TKI will be done according to investigator’s clinical practice. Primary objective: to compare clinical benefit, as measured by overall survival (OS), provided by CN followed by TKIs vs upfront TKIs in pts with mRCC. Secondary objectives: i) to compare clinical benefit, as measured by progression-free survival (PFS) and response rate (RR) provided by CN followed by TKIs vs upfront TKIs; ii) Safety; iii) Exploratory analyses: evaluation of the predictive role of circulating tumor cells count and circulating tumor DNA at baseline, before and after surgery (in pts undergoing CN), 24 weeks after randomization and at the time of disease progression. Key inclusion criteria: Favorable or intermediate MSKCC or Heng prognostic risk group; histological diagnosis of RCC with a clear-cell component; resectable asymptomatic mRCC with primary tumor in place; up to three different metastatic sites; ≥ 3 metastatic lesions. Key exclusion criteria: Widespread disease ( > or = 4 metastatic organ sites); disease suitable of metastasectomy ( < 3 lesions confined at one organ site). Statistical plan: The sample size was calculated in order to compare 5-year OS between subjects randomized to receive CN followed by TKIs and those randomized to receive upfront TKIs. A total of 191 deaths will yield 80% power to detect a hazard ratio of 1.5 of upfront TKIs vs CN followed by TKIs with an overall type 1 error of 0.05 (two-sided log-rank test). Such a HR corresponds to an increase in the 5-year OS, from an anticipated value of 10% for TKIs to 21.5% for CN followed by TKIs. To date 10/270 pts have been enrolled. Clinical trial information: NCT02535351.

TPS5093 Background: PC is a radiosensitive disease. PSMA is selectively overexpressed in advanced PC with upregulation by androgen receptor (AR) pathway dysregulation; limited expression exists in other organs. A series of sequential studies of radiolabeled anti-PSMA antibody J591 revealed 1) targeting and safety [Bander 2003]; 2) safety and prelim efficacy [Milowsky 2004, Bander 2005]; 3) efficacy and initial dose-response [Tagawa 2013]; 4) dose-fractionation allows higher doses, ability to combine with docetaxel, confirmation of dose-response (PSA and overall survival) [ASCO 2010, 2014, 2016]; 5) predictable, reversible myelosuppression is dose-limiting [Tagawa 2013]. Small molecule PSMA inhibitor ligands can be successfully radiolabeled and are widely used for imaging and treatment in Europe. 177Lu-PSMA-617 is the most commonly used, but experience is mostly anecdotal/retrospective and no formal dose-escalation studies have been performed. Methods: Men with progressive mCRPC following at least 1 potent AR-targeted agent (e.g. abi/enza) and docetaxel (or unfit/refuse chemo) without limit of # prior therapies provided adequate organ function will undergo imaging with 68Ga-PSMA-HBED-CC PET/CT followed by escalating fractionated doses of 177Lu-PSMA-617. Cohort 1 = 3.7 GBq x2 two weeks apart up to 11.1 GBq x2 in a 3+3 dose-escalation study. Dose-limiting toxicity (DLT) is defined as attributable grade 4 heme toxicity or grade 3/4 non-heme toxicity. Planned cohort expansion will occur at recommended phase 2 dose (RP2D) in a 2-stage design. The primary endpoint is determination of DLT and RP2D. Secondary endpoints include toxicity, PSA decline rate, RECIST response, PFS, rPFS, OS. Correlatives include baseline/follow up PSMA imaging, whole body distribution of 177Lu-PSMA-617, CTC count (CellSearch) changes, tissue and circulating genomic assessment of DNA repair pathways, patient reported outcomes (FACT-P and BPI-SF). Clinical trial information: NCT03042468.

TPS5600 Background: Cervical cancer is a leading cause of cancer death in women worldwide. Image-guided bone marrow-sparing intensity modulated radiation therapy (IG-BMS-IMRT) has shown potential to reduce acute toxicity of chemoradiotherapy and improve chemotherapy delivery in phase I and II trials (Mell LK, Sirák I, Wei L, et al. Bone Marrow-sparing IMRT With Concurrent Cisplatin For Stage IB-IVA Cervical Cancer: An International Multicenter Phase II Clinical Trial (INTERTECC-2). Int J Radiat Oncol Biol Phys 2017;97:536-545. Mell LK, Saenz CC, Yashar CM, et al. Phase I Trial of Bone Marrow Sparing IMRT With Concurrent Cisplatin and Gemcitabine in Stage IB-IVA Cervical Cancer (abstr.) Int J Radiat Oncol Biol Phys 2016; 96: S14.). Methods: INTERTECC-3 is a randomized phase III trial designed to test the effect of IG-BMS-IMRT on progression-free survival (PFS) for women with unresected FIGO stage IB-IVA cervical carcinoma (clinicaltrials.gov #NCT01554397). It presently involves centers in the U.S., Czech Republic, U.K., India, Japan, and China. Women are randomized 3:2 to either (A) IG-BMS-IMRT or (B) standard chemoradiation, with 6 cycles of concurrent cisplatin (40 mg/m2) weekly in both arms. Secondary objectives are to compare overall survival, treatment-related toxicity, disease recurrence, quality of life, chemotherapy delivery, and radiation quality assurance. Planning objectives require maintaining pelvic marrow and active marrow mean doses < 27 Gy and < 28.5 Gy respectively. Correlative studies involve longitudinal collection of magnetic resonance restriction spectrum imaging and 18F-fluorothydimine positron emission tomography scans to assess imaging biomarkers of treatment response in select patients. 415 women will be enrolled to determine if IG-BMS-IMRT improves the median PFS from 3.2 to 5.0 years with 80% power and alpha = 0.05. INTERTECC-3 opened in the U.S. and Czech Republic in 2016. To date, 17 patients have been randomized. The trial will be activated at additional international sites in late 2017 and 2018. We are seeking to recruit sites who wish to collaborate. Clinical trial information: NCT01554397.

TPS5609 Background: There is an urgent need to improve outcomes for patients with platinum-resistant and refractory ovarian cancer (PROC). OCTOPUS is an umbrella phase II framework for testing whether the addition of novel targeted agents to weekly paclitaxel (wPxl) improves efficacy in PROC. The first agent to be evaluated is the dual mTORC1/mTORC2 inhibitor, vistusertib (AZD2014), as preclinical studies support targeting the PI3kinase/Akt/mTOR pathway in PROC and the combination of vistusertib and wPxl has shown promising preliminary activity in high grade serous ovarian cancer (HGS) patients in a phase I trial (Banerji et al poster discussion ESMO 2016). This is the first randomised trial of wPxl and a dual mTORC1/2 inhibitor in ovarian cancer. Methods: OCTOPUS is an investigator-initiated, randomised, double-blind, placebo-controlled, multicentre, phase II trial. 140 patients with PROC (histologically confirmed HGS) are randomised 1:1 to receive wPxl (80mg/m2 D1, D8, D15 of 28 day cycle) plus oral vistusertib (50mg BD) or placebo (D1-3, D8-10, D15-17). The primary endpoint is progression-free survival (PFS) based on combined RECIST v1.1/GCIG CA125 criteria. The study is designed to detect a 50% improvement in median PFS from 3.7 months on placebo to 5.55 months on the experimental arm with 90% power, at the 20% 1-sided level of statistical significance (or equivalently with 80% power at the 10% level of statistical significance) using a 3-outcome design. Secondary endpoints include response (based on RECIST 1.1 and GCIG CA125 criteria), overall survival, toxicity and quality of life. Patients whom received prior wPxl for PROC are not eligible. A mandatory pre-treatment biopsy (if technically feasible), archival tissue, and serial blood samples will be collected for translational research studies. 49 patients have been recruited. The study is part of the NIHR CRN Cancer/Astrazeneca Alliance, sponsored by NHS Greater Glasgow and Clyde/University of Glasgow and endorsed by Cancer Research UK (CRUKE/14/052). Clinical trial information: ISRCTN16426935.

TPS5612 Background: Endometrial cancer (EC) patients with advanced or recurrent disease and endometrioid histology have a short progression-free survival (PFS). These malignancies are hormone dependent and endocrine therapy with aromatase inhibitors is well established. Palbociclib is an oral and selective inhibitor of cyclin-dependent kinases CDK4 and CDK6. Studies in breast cancer have demonstrated superiority of letrozole treatment in combination with palbociclib vs. letrozole monotherapy in oestrogen receptor positive (ER+) HER2- advanced disease. The combination is generally well tolerated with an acceptable toxicity profile. This multicenter, prospective, double-blind, placebo-controlled, randomized, phase II trial is evaluating the efficacy of letrozole when combined with palbociclib against letrozole-placebo combination therapy in women with ER+ advanced or recurrent EC. Methods: The primary objective of this trial is to demonstrate superiority of palbociclib against placebo in combination with letrozole, as defined by investigator-assessed progression-free survival (PFS). Key eligibility criteria include: histologically confirmed ER+ EC of endometrioid type; stage 4 or recurrent disease; prior surgery, adjuvant chemotherapy, radiation therapy, hormonal therapy (e.g. megestrol acetate) is permitted; measurable/evaluable disease according to RECIST 1.1. 78 patients will be randomized 1:1 to receive palbociclib 125mg daily or placebo on days 1-21 and letrozole 2.5mg daily on days 1-28 in a 28 days cycle until disease progression, unacceptable toxicity, or withdrawal. Secondary endpoints include PFS in sub-populations, overall response rate, disease control rate, PFS2, time to first subsequent therapy, time to second subsequent therapy, overall survival, safety & tolerability, patient reported outcomes (assessed via EORTC QLQ-C30 and EORTC QLQ-EN24) and PFS in patients with or without retinoblastoma protein-expressing tumors. The following cooperative groups are participating: NSGO (DK, FIN, NOR), MITO (ITA), GEICO (SPA) & NOGGO (GER). Clinical trial information: NCT02730429.

TPS5615 Background: The Cancer Genome Atlas project identified 2 groups of hypermutated endometrial cancers (ECs): an ultramutated group that harbored mutations in the exonuclease domain of polymerase e ( POLE), and a hypermutated group with microsatellite instability (MSI), the majority of which harbored MLH1 promoter methylation. We (Howitt, JAMA Onc 2015) and others have shown that POLE and MSI ECs are associated with higher number of predicted neoepitopes and tumor infiltrating lymphocytes, which is counterbalanced by overexpression of PD-1/PD-L1, suggesting that they may be excellent candidates for PD-1/PD-L1 blockade. Anti-PD-1 therapy has also demonstrated promising activity in mismatch repair deficient colorectal cancers and collectively in non-colorectal cancers (Le, NEJM 2015). Methods: This is an open-label, two-cohort, two-stage, phase 2 trial, of avelumab, a fully human IgG1 antibody directed against PD-L1, in two cohorts: i) a MSI/ POLE cohort including ECs with immunohistochemical (IHC) complete loss of expression of at least one of the mismatch repair (MMR) proteins and/or documented mutation in the exonuclease domain of POLE and ii) a MSS cohort including ECs with normal IHC expression of all MMR proteins. Key eligibility criteria include measurable disease, no upper limit of prior therapies, and any EC histology. Co-primary objectives include objective response rate and rate of progression-free survival at 6 months. Avelumab is administered at 10 mg/kg as 1-hour IV infusion every 2 weeks until disease progression or unacceptable toxicity; therapy may continue at the investigator’s discretion while awaiting radiologic confirmation of disease progression 4 weeks later. Maximum target enrollment is 70 patients (35 for each cohort). In the first stage, 16 patients will be enrolled in each cohort; if there are at least two objective responses or two patients progression-free at 6 months, accrual will continue to the second stage where 19 more patients will be enrolled for each cohort. Thus far, 16 patients have been enrolled, 13 on the MSS cohort and 3 on the MSI/ POLE cohort. Clinical trial information: NCT02912572.
