TPS3166 Background: Inactivation of tumor protein 53 (TP53) is a central mechanism of tumors to promote survival and proliferation. The murine double minute 2 ( MDM2) oncogene is the primary cellular negative regulator of TP53. Small molecule inhibitors of the MDM2-p53 interaction are currently being evaluated in clinical trials as new anti-cancer drugs, and clinical data published to date support the rationale to target MDM2-amplified tumors. BI 907828 is a potent MDM2-p53 antagonist that has shown efficacy in mouse models of human cancer. Methods: NCT03449381 is a Phase 1a/1b, open-label, multicenter, dose-escalation trial of BI 907828 in patients aged ≥18 years with advanced/metastatic solid tumors. Primary objectives of the Phase 1a (dose-escalation) part are to determine: the maximum tolerated dose (MTD) of BI 907828 based on dose-limiting toxicities (DLTs) during the first treatment cycle; the recommended dose for expansion (RDE); safety and tolerability. Patients in Arm A will receive one dose of BI 907828 every 21 days, and patients in Arm B one dose on Days 1 and 8, every 28 days. Secondary objectives include pharmacokinetics (PK), pharmacodynamics (PD) [GDF-15 induction in plasma], and preliminary anti-tumor activity. Primary endpoints are the number of patients with DLTs during the first treatment cycle, and the MTD. Phase 1a will include ≈50 evaluable patients with locally advanced or metastatic solid tumors with either a known TP53 wild type (wt) status or unknown TP53 status, regardless of MDM2 amplification status at the time of study entry. The main objectives of Phase 1b (expansion cohorts) are to assess efficacy, safety, and PK profiles at the RDE, and to determine the recommended dose for Phase 2. The primary endpoint is objective response, where best response is determined according to RECIST v1.1, or RANO criteria for patients with glioblastoma. Phase 1b will include up to 150 evaluable patients with TP53 wt tumors, assigned to four different cohorts, including non-squamous NSCLC, soft tissue sarcoma, glioblastoma, urothelial carcinoma, and solid tumors with brain metastases. As of 8th February 2019, 11 patients have been enrolled. Clinical trial information: NCT03449381.

TPS3167 Background: CDC7 is a protein with key roles in DNA replication initiation, the intra-S-phase checkpoint and M-phase completion. CDC7 is over-expressed in malignant compared to non-malignant cells, particularly those with TP53 mutations, making it an attractive therapeutic target. LY3143921 hydrate is an orally administered ATP-competitive CDC7 inhibitor. Pre-clinical studies in colorectal cancer (CRC) and squamous non-small cell lung cancer (sqNSCLC) demonstrate favourable anti-cancer activity, particularly in squamous NSCLC and in CRC with TP53 null and missense mutations. We hypothesise that solid tumours mutated in TP53 will be sensitive to LY3143921 therapy. Methods: This is a first-in-human, phase I trial of LY3143921 hydrate (LY3143921) monotherapy given twice daily, continuously on a 21 day schedule until disease progression, patient (pt) withdrawal or unacceptable toxicity (NCT03096054). Eligible pts have histologically proven advanced/metastatic solid tumours for which no further standard therapy exists and WHO PS 0-1. Pts have regular clinical assessment and tumour imaging every 2 cycles. Phase Ia (dose escalation) is recruiting in a 3+3 design following 3 initial single patient cohorts (starting dose 30 mg OD), enriching for patients with malignancies associated with p53 mutations (CRC, sqNSCLC, high grade serous ovarian, squamous cell oesophageal, squamous cell head & neck, urothelial, pancreatic and triple negative breast cancer). Recruitment to cohort 6 (180 mg BD) is ongoing. On determination of the maximum tolerated dose (MTD) and recommended phase II dose and schedule (RP2D), 2 expansion cohorts (≤ 25 pts each) of patients with CRC and sqNSCLC will be evaluated. Primary objectives: assess safety and tolerability of LY3143921, determine MTD and RP2D. Secondary objectives: evaluate preliminary efficacy and PK profile of LY3143921. All pts will have archival tumour tissue retrospectively analysed, while patients in phase Ib will also have pre- and on-treatment tumour biopsies. Evaluation of potential predictive and pharmacodynamic biomarkers including p53 mutations, phosphorylated MCM2, cyclin B1 and molecular subgroups of target tumours will be included. Clinical trial information: NCT03096054.

TPS3615 Background: Colon cancer with deficient mismatch repair (dMMR) and POLE mutations are characterised by a high tumor mutational burden (TMB) and an immunogenic lymphocyte infiltrate. Approximately 12% of stage III colon cancer have dMMR. POLE mutations occur in 1% of colon cancers, but is enriched in patients <50 years of age. Colon cancer with high TMB have demonstrated to be sensitive to immune checkpoint inhibition in the metastatic setting. We are conducting a phase III randomised trial to determine if the addition of the anti-PD-L1 antibody, avelumab following adjuvant chemotherapy can improve disease free survival (DFS) in patients with stage III colon cancer with dMMR or POLE mutations. Methods: We are recruiting patients with curatively resected, stage III colon cancer which are dMMR or have a centrally confirmed POLE exonuclease domain mutation. Eligible patients are randomised in a 1:1 ratio to standard fluoropyrimidine-based chemotherapy (CAPOX [capecitabine, oxaliplatin] for 12 weeks or capecitabine for 24 weeks) or chemotherapy followed by avelumab (10mg/kg, 2 weekly for 24 weeks). Stratification is by chemotherapy received and MMR status. The primary endpoint is DFS. Secondary endpoints include overall survival, toxicity, quality of life, and health resource use. Exploratory objectives will investigate circulating, tumor and stool based biomarkers of avelumab benefit. The 3-year DFS rate in the control arm is expected to be ~75%. Avelumab is expected to improve the 3-year DFS rate by 12% (i.e. 87%). Target accrual is 402 patients which provides 80% power to detect a hazard ratio of 0.48 for DFS at a two–sided alpha of 0.05. This trial is a national, multi-centre phase III trial and it is anticipated that approximately 40 centres in the UK will participate. This study opened to recruitment in August 2018. Clinical trial information: NCT03827044.

TPS3621 Background: A randomized phase II trial, DEEPER (JACCRO CC-13) [NCT02515734], is on-going to evaluate FOLFOXIRI plus cetuximab (cet) vs. FOLFOXIRI plus bevacizumab (bev) in terms of depth of response as primary endpoint in 360 mCRC patients (pts) with RAS wild-type tumors, PS0-1, and no previous chemotherapy. This is a head-to-head comparative trial of 2 key monoclonal antibodies in mCRC treatment; therefore, it would be of interest to perform the biomarker study for developing novel predictors of cet or bev. The clinical utility of circulating tumor DNA (ctDNA) analysis has been largely validated for monitoring during treatment and companion diagnostics after chemotherapy. However, there are few published results regarding ctRNA in cancer treatment. Use of ctRNA from liquid biopsies would enhance tumor profiling through the trending of actionable biomarkers not found in ctDNA, and allow for patient monitoring by measuring dynamic changes in levels of gene expressions. Methods: This study will enroll pts with willing to undergo biopsies of both tissue and blood among participants of the DEEPER trial. The estimated number is 250. The main purpose is to find novel predictors for efficacy of cet or bev in mCRC using liquid biopsies, which are performed to obtain ctDNA and ctRNA at 6 time points: pre-treatment, 8 weeks after treatment start, beginning of maintenance phase in FOLFOXIRI-regimen, progression, before and 8 weeks after 2nd-line treatment. The tissue samples collected before chemotherapy will be used for analyzing intra-tumoral genetic alterations. Associations between analytes in blood/tissue and the clinical outcomes of each treatment (with cet or bev) will be assessed using Fisher’s exact test, Kaplan-Meier curves, and log-rank tests in univariate analyses. We will evaluate on whether transcriptomic analysis in ctRNA could predict treatment efficacy more accurately compared to genomic analysis in ctDNA, and verify the clinical utility of ctRNA testing in mCRC treatment. Accrual will continue until the DEEPER trial is completed. Clinical trial information: UMIN000018412.

Published: May 2019

TPS3622 Background: Standard neoadjuvant long course chemoradiotherapy (LCCRT) for locally advanced rectal cancer (LARC) results in a complete pathological response rate of 10-30%: but 20-40% of patients (pts) are non-responders, 10-15% have local recurrence. Tumoural immune infiltrates are predictive of response. Preclinical studies show that radiotherapy (RT) via interferon signaling is immuno-stimulatory, enhancing local/distant tumour cell death. RT also stimulates PDL1 production and the immunosuppressive activity of myeloid derived suppressor cells. Hence PDL1 inhibition may be required to enhance the immuno-stimulatory effects of RT. Hypothesis: In pts with resectable LARC, the anti-PDL1 antibody Avelumab post LCCRT may enhance the pathological/imaging response rates whilst potentially reducing local/distant relapse rates. Methods: (1) Trial Design: Phase II single arm trial, across 6 Australian sites (2) Endpoints: (a) Primary; Pathological response rate post-LCCRT, as documented by central pathologist, (b) Secondary; MRI/FDG PET imaging responses at 8 weeks post LCCRT (pre-surgery). Toxicity. (c) Exploratory; Tumoural immune cell subsets/checkpoint expression (by multiplex immunohistochemistry and in-vitro functional assays) and ctDNA analysis at baseline and during treatment. Distant relapse-free survival and the documentation of sites of relapse. (3) Sample size: An increase in the proportion of pathological complete responses by > 25% (from 10% to 35%) will be considered clinically important. Power = 90%, α = 0.05, 41 pts are required– an additional 4 pts to allow for drop-out. Total sample size = 45pts. Treatment: All pts to receive standard LCCRT (50.4Gy RT plus 5FU [225mg/m2/day/CI] or Capecitabine [825mg/m2 BID on RT days] over 5.5 weeks). Post LCCRT (prior to surgery), pts receive 4 cycles Avelumab (10mg/kg, q2 weeks). Surgical resection 10-12 weeks post LCCRT. Fresh tumour biopsy and ctDNA sampling pre LCCRT, pre Cycle 1 Avelumab and at surgery. Response by FDG PET and pelvic MRI pre surgery. Pts to be followed up for 2 years. Major Inclusion Criteria: Pts with LARC, MRI stage T3b-4/N1-2/M0, planned for LCCRT followed by curative resection, tumoural lower border within 12cm from the anal verge, measurable disease (RECIST1.1), ECOG 0-1, adequate organ function and no contraindications to Avelumab therapy. Current Enrolment: 11 of the planned 45 patients enrolled. Clinical trial information: NCT03299660.

TPS4144 Background: The majority of patients (pts) with gastroesophageal cancer present with inoperable or metastatic disease and there is a strong need for efficient and tolerable first-line (1L) treatment. Oxaliplatin-based regimens like FOLFOX have become one standard of care. However, median survival is still below 12 months. Results from trials using nivolumab plus ipilimumab treatment of subjects with advanced/metastatic GC and GEJ cancers demonstrated clinical activity, in pts whose tumors did or did not express PD-L1; in addition, nivolumab alone and in combination with ipilimumab demonstrated clinical benefits in various other tumor types. Based on this clinical experience, the AIO-STO-0417 trial (Moonlight) has been designed to evaluate the combination of chemotherapy with two checkpoint inhibitors in first-line therapy of pts with gastroesophageal adenocarcinoma. Methods: This is a prospective, multicenter, randomized, investigator-initiated phase II trial. Pts with Her2-negative, inoperable, advanced or metastatic gastric or esophagogastric junction cancer will be randomized 1:1 to 1L treatment with FOLFOX (Oxaliplatin 85 mg/m²; Leucovorin 400 mg/m²; 5FU 400 mg/m² on d1 of each treatment cycle and 5FU 1200 mg/m² continuous infusion over 24 hrs d1 and d2) every 2 weeks plus Nivolumab 240 mg every 2 weeks and Ipilimumab 1mg/kg every 6 weeks (Arm A) or FOLFOX alone (Arm B). Primary endpoint of the trial is progression-free survival based on the ITT population. Main secondary endpoints are overall survival, objective response rate, Safety and Quality of life (EORTC QLQ-C30). 118 pts (59 per arm) will be enrolled to provide 80% power for detecting an average HR of 0.68 using the log rank test at a one-sided type I error of 10%. At the date of submission, (Feb 2019), 28 of planned 118 pts are randomized. Clinical trial information: NCT03647969.

TPS4146 Background: Combination therapy with the anti-HER2 antibody trastuzumab with fluoropyrimidine and platinum is the current standard for patients with HER2+ mG/GEJc. We hypothesize that combination anti–PD-1 and anti-HER2 therapy will result in T-cell activation, augment ADCC, and potentiate antitumor immune response in HER2+ patients. This phase 2 study in HER2+ mG/GEJc demonstrated the safety and preliminary efficacy of trastuzumab/pembrolizumab/chemotherapy; the overall response rate was 87%, and the disease control rate was 100% Janjigian YY, ASCO GI 2019). KEYNOTE 811, a global, multicenter, randomized, placebo-controlled, phase 3 study, is underway. Methods: Key eligibility criteria are age ≥18 years; previously untreated unresectable or metastatic HER2+ (centrally confirmed IHC 3+ or IHC 2+/ISH >2.0) G/GEJ adenocarcinoma; life expectancy >6 months with RECIST v1.1 measurable disease; adequate organ function and performance status. Patients will be randomly assigned 1:1 to receive chemotherapy with pembrolizumab 200 mg IV flat dose or placebo with trastuzumab 6 mg/kg (after 8 mg/kg load) Q3W up to 2 years or until intolerable toxicity or disease progression. Investigator choice chemotherapy will include day 1 cisplatin 80 mg/m2 IV and /5-fluorouracil 800 mg/m2/day IV (days 1-5) or oxaliplatin 130 mg/m2 IV and capecitabine 1000 mg/m2 BID days 1-14 (Q3W). Primary end points are progression-free survival and overall survival. Secondary end points are objective response rate, duration of response, and safety and tolerability. Adverse events are graded per NCI CTCAE v4.0 and will be monitored for 30 or 90 days after treatment. Patients will be followed up for survival. Planned enrollment is approximately 692 patients.

TPS4152 Background: Len, an inhibitor of VEGF receptors 1-3, FGF receptors 1-4, PDGF receptor α, RET, and KIT, is approved for first-line treatment of unresectable HCC (uHCC) based on the open-label phase 3 REFLECT study in which len showed noninferior overall survival (OS) and significantly improved objective response rate (ORR), progression-free survival (PFS), and time-to-progression (TTP) vs sorafenib. In the phase 2 KEYNOTE-224 study of pembro (a PD-1 inhibitor) as second-line treatment of advanced HCC, pembro showed meaningful clinical efficacy in pts previously treated with sorafenib, with median PFS 4.9 mo, median OS 12.9 mo, and a manageable safety profile. In results from the phase 1b KEYNOTE-524 trial, len+pembro was well-tolerated, with promising antitumor activity in pts with uHCC. LEAP-002 is a phase 3 study to evaluate the safety and efficacy of len+pembro vs len+placebo as first-line therapy for advanced HCC. Methods: Eligible pts are ≥18 y and have HCC confirmed by radiology, histology, or cytology; ECOG PS 0/1; BCLC stage C or stage B disease not amenable to locoregional therapy or curative treatment approach; CP class A liver score within 7 days before study; and ≥1 measurable lesion by RECIST v1.1. Pts with past or ongoing HCV infection and those with controlled HBV are eligible. 750 pts will be randomized 1:1 to receive len 12 mg (body weight [BW] ≥60 kg) or 8 mg (BW <60 kg) orally once daily plus pembro 200 mg or placebo IV Q3W. Pembro and len will be administered until disease progression or unacceptable toxicity, with a maximum 35 cycles for pembro. Stratification will be by geographic region (Asia vs Japan and Western regions); macroscopic portal vein invasion or extrahepatic spread or both (yes or no); alpha fetoprotein ≤400 ng/mL vs >400 ng/mL; and ECOG PS 0/1. Primary end points are PFS per RECIST v1.1 by blinded independent central review (BICR) and OS. Secondary end points are ORR, duration of response, disease control rate, and TTP per RECIST v1.1 by BICR, efficacy per modified RECIST, pharmacokinetics, and safety. Imaging assessments will be performed Q9W on study. AEs will be graded per CTCAE v4.0 and monitored up to 90 days after last dose. Clinical trial information: NCT03713593.
A multicenter phase II trial of rucaparib in combination with nivolumab as maintenance therapy for patients with advanced biliary tract cancer.
Authors: Sahai Vaibhav , Tran Nguyen H. , Griffith Kent A. , Zalupski Mark 
Published: May 2019

TPS4153 Background: Patients (pts) with advanced biliary tract cancers (BTC) have a poor prognosis with a median overall survival (OS) less than 12 months. Using whole exome NGS, 26 (49%) pts in a 53 pt cohort had either DNA damage repair (DDR) pathway mutations (somatic and/or germline, n = 18), or isocitrate dehydrogenase 1 (IDH1) mutations (n = 8), and may have potentially benefited from PARP inhibition. Further, disruption of the mutated DDR pathways with a PARP inhibitor may result in increased mutational burden and neoantigens leading to immunogenicity, thus providing the rationale for combination with a PD-1 antibody. This phase 2 trial is designed to investigate the role of a PARP inhibitor in combination with a PD-1 antibody in pts with advanced BTC. Methods: Key eligibility criteria include histologically confirmed advanced, unresectable biliary adenocarcinoma (intra- or extra-hepatic, and gallbladder) without progression after 4-6 months of 1st line platinum-based systemic chemotherapy, measurable disease per RECIST v1.1, ECOG PS 0-1, Child-Pugh A or B7, and absence of autoimmune disease or chronic steroid use. Primary objective is to evaluate progression-free survival (PFS) rate at 4 months. Secondary objectives include evaluation of objective response rate per immune related (ir)RECIST criteria, median PFS and OS, and safety in this patient population. Exploratory objectives include identification of predictive biomarkers of response and mechanisms of resistance through serial biopsies and blood collection (pre, on and post therapy), including sequential whole exome/transcriptomic analysis with immune cell subset analysis. Treatment includes rucaparib 600 mg PO BID on days 1-28 with nivolumab 240 mg on days 1, 15 Q4 weeks. In absence of disease progression, pts may continue therapy up to 2 years. Accrual goal is 32 evaluable pts. Using a null hypothesis value of a 63% PFS rate at 4 months, and an 85% alternative hypothesis, this ongoing study has 80% power, with a one-sided alpha of 0.05 to identify treatment efficacy in the study arm. Clinical trial information: NCT03639935.
