TPS3617 Background: Patients with metastatic colorectal cancer (mCRC) with progressive disease on/after or who are intolerant to fluoropyrimidines, oxaliplatin, irinotecan, anti-angiogenic and anti-EGFR therapies have limited therapeutic options and a dismal prognosis, with a median survival below 6 months. Recently, Trifluridin/Tipiracil (TAS102) significantly improved survival in patients with refractory mCRC and ramucirumab has been approved in combination with FOLFIRI for the treatment of patients with mCRC after prior FOLFOX/bevacizumab first line therapy. Previous studies on both components provide a strong rationale to conduct a randomized study evaluating the efficacy and safety of ramucirumab in combination with TAS102 in patients with refractory mCRC to improve efficacy and prevent resistance. Methods: This is an interventional, randomized, open label, multicenter, phase IIb study in patients with advanced mCRC. Eligible patients will be randomized 1:1 and receive either ramucirumab and TAS102 (ramucirumab 8 mg/kg on d1+15, q4w and TAS102 35 mg/m² on d1-5 and d8-12, q4w) or TAS102 alone. Primary endpoint is overall survival as assessed by the Kaplan-Meier method, assuming a 6 months survival probability of 70% with ramucirumab in combination with TAS102 and 58% with TAS102 alone. Treatment groups are compared using the log-rank test. A total of 144 patients will be enrolled at 30 sites (1-sided alpha 0.10, power 0.80). Main secondary endpoints are overall response rate, disease control rate, progression free survival and quality of life. In addition, a large comprehensive translational research program will be conducted to identify novel predictive and prognostic biomarkers. The study started in December 2018. By February 2019, a total of 3 patients have been enrolled. Clinical trial information: NCT03520946.

TPS3619 Background: In the first-line setting, current combination chemotherapy (CT) achieve high objective response rates (ORR) ranging from 40% to 80% and leads to complete resection rate (CRR) of colorectal cancer liver metastasis (CRCLM) in 25% to 50% of patients with initially non-resectable CRLM. However, when patients with CRLM are still not amenable to resection after induction CT, ORRs (~5-30%) and CRRs ( < 10%) obtained with second-line systemic CT are much lower. Combining hepatic arterial infusion (HAI) and systemic (SYS) CT for unresectable CRLM lead to high ORR and the potential of cure in the second-line and further setting. Methods: This multicenter randomized phase II trial conducted in 20 centers in France plans to include 140 patients with CRLM still not amenable to a curative intent-treatment after at least two months of first-line induction SYS CT whatever the tumor response. Patients are randomized (1:1) between intensified biweekly regimen combining HAI oxaliplatin (100 mg/m²) and SYS FOLFIRI (leucovorin 400 mg/m², irinotecan 180 mg/m², and 5-FU 2.4 g/m²over 48 h) plus cetuximab 500 mg/m² or bevacizumab 5 mg/kg (according to RAS status and prior response/tolerance to SYS induction CT) or SYS CT alone according to current guidelines. The primary endpoint is to evaluate and compare the curative-intent (R0-R1) resection (and/or ablation) rate (CRR) of CRLM in both arms. A gain of 20% in CRR is expected (30% in the experimental arm vs. 10% in the control arm; α 5% [two-sided]; β 20%). Stratification factors at randomization are prior adjuvant or SYS induction oxaliplatin-based CT, tumor response to SYS induction CT, and center. Secondary endpoints include progression-free (overall, hepatic and extrahepatic) and overall survival, ORR, relative change in the sum of longest diameters of RECIST target lesions (DoR) and feasibility/tolerability. Since study start, 3 patients have been enrolled to date (planned accrual period: 3 years). Clinical trial information: NCT03164655.

Published: May 2019

TPS3620 Background: Locally advanced rectal cancer remains a clinical challenge with few improvements noted over the past few decades. Although immunotherapy has no current clinical role in microsatellite stable (MSS) colorectal cancer, preclinical models suggest that radiotherapy (RT) can enhance neoantigen presentation, modulate the microenvironment, and improve the likelihood of anti-tumor activity with checkpoint inhibitor use. This prospective phase II trial will test that hypothesis in addition to confirming the safety of this approach using a “window-of-opportunity” study design with the anti-PD-L1 agent durvalumab (MEDI4736). Methods: This multi-center phase II trial is currently enrolling patients (pts) with rectal cancer who are undergoing standard NCCN guideline-compliant neoadjuvant chemoradiotherapy (CRT). Eligibility includes pts with MSS stage II-IV rectal cancer with adequate organ function and pre-treatment diagnostic tumor available for profiling who are undergoing CRT with intent to proceed to surgical resection. Stage IV disease must be limited such that the primary pelvic tumor requires definitive management. Standard ineligibility criteria include active infections, systemic steroid use, or other conditions making immunotherapy use unsafe. Treatment includes durvalumab (750mg IV infusion once every 2 wks) for 4 total doses beginning within 3-7 days after CRT completion. Surgery must be within 8-12 wks of the final CRT dose. Primary endpoint is a demonstrated improvement in Neoadjuvant Rectal Cancer (NAR) score compared to historical controls targeting a 20% relative risk reduction in DFS and 3-4% absolute OS improvement. Secondary endpoints include OS, DFS, toxicity, pCR, cCR, therapy completion, negative surgical margins, sphincter preservation, off-target “abscopal” effects for the subset of stage IV pts, and exploratory assessments of tumor infiltrating lymphocytes, circulating immunologic profiles, and molecular predictors of response. A safety run-in phase has completed as a precedent to full enrollment. Enrollment now continues to 47 total pts to achieve 41 surgically evaluable pts. Support: AstraZeneca-Medimmune, NSABP Foundation. Clinical trial information: NCT03102047.

TPS3623 Background: Adjuvant chemotherapy is the current standard treatment for stage III colorectal cancer after curative resection. However, the prognosis of stage III colorectal cancer is still poor even after curative resection and adjuvant chemotherapy. Recently, several observational studies suggested the anti-tumor effect of aspirin for advanced colorectal cancer. The main mechanism of the anti-tumor effect by aspirin may be to suppress cyclooxygenase activity in the arachidonic acid cascade and to inhibit the production of prostaglandins involved in tumor growth. So far, aspirin showed a prolongation of survival for colorectal cancer in several retrospective studies. However, in these studies, aspirin was given not to be evaluated the effect on prognosis of colorectal cancer in adjuvant setting but to prevent cardiovascular event. In addition, baseline patient characteristics were imbalanced between aspirin group and non-aspirin group and both dosage amount and dosing period of aspirin were different among patients. Methods: We planned a randomized double-blind placebo-controlled phase III trial commenced in Japan in March 2018 to confirm the superiority of aspirin in terms of disease-free survival (DFS) over placebo for stage III colorectal cancer patients after curative resection. Patients receive aspirin (100 mg/day) or placebo for 3 years with the standard adjuvant chemotherapy of mFOLFOX6, CAPOX or capecitabine until relapse or unacceptable toxicities. The primary endpoint is DFS and the secondary endpoints are overall survival, relapse-free survival, relative dose intensity, adverse events, and serious adverse events. We assumed the 3-year DFS of aspirin arm as 74% based on two previous trials conducted by JCOG and expected a 6% increase in the 3-year DFS with aspirin adding to standard adjuvant chemotherapy after curative surgery. A total of 880 patients will be accrued from 20 Japanese institutions within 3 years, and 47 patients were enrolled as of Jan 31, 2019. Both aspirin and placebo are provided by Bayer Yakuhin Ltd. This trial has been registered at Japan Registry of Clinical Trials as jRCTs031180009 (https://jrct.niph.go.jp/detail/589). Clinical trial information: jRCTs031180009.

TPS3624 Background: There is now a body of evidence indicating a potential role for aspirin in colorectal cancer (CRC) prevention. In cardiovascular trials, effects on incidence of cancer metastases and short-term mortality suggest further possible roles in the treatment setting, supported by observational studies of aspirin use after cancer diagnosis. In the prevention setting, aspirin use has been limited by toxicity concerns, particularly of serious bleeding. In the adjuvant setting, benefits associated with reducing recurrence and subsequent treatment may outweigh these risks. The Add-Aspirin trial will investigate this, and will also consider possible mechanisms of action for aspirin effects, including the impact of PIK3CA mutations, where there are currently several theories and conflicting data. Methods: Add-Aspirin (ISRCTN74358648) is an international, phase III, double-blind, randomised, placebo-controlled trial recruiting patients who have undergone surgery and relevant adjuvant treatment for stage II or III CRC, as well as those with completely resected CRC liver metastases. Parallel randomised cohorts will address the question in breast, gastro-oesophageal and prostate cancer. Participants take aspirin 100mg daily for an 8-week run-in, to assess adherence and toxicity, and those suitable to proceed are randomised (1:1:1) to aspirin 100mg, aspirin 300mg or placebo daily for at least 5 years. A number of measures – including blood pressure control and PPI use where relevant - are in place to reduce bleeding risk. The primary outcome is disease-free survival (target hazard ratio = 0.8, n = 2600 in 5 years) with a long term analysis of survival planned across the tumour groups. Translational work includes a sub-study monitoring urinary thromboxane B2 as a marker of platelet activation in a subgroup (n = 500) to investigate mechanisms of action. Add-Aspirin opened in 2015 and recruited 1505 CRC patients during the first 3 years from 137 UK centres. 1282 (85%) proceeded to randomisation. A pre-planned feasibility analysis of run-in data (n = 2253 across all 4 tumour groups) provided reassuring data on safety, tolerability and adherence, and recruitment continues with centres in India and Republic of Ireland recently joining.

TPS4148 Background: Combination of ramucirumab and paclitaxel resembles the standard treatment option in second line therapy with improvement of response rate and overall survival (REGARD, RAINBOW). Response rates to PD-1/L1 blockade in gastro-esophageal cancer patients rank within 10–20%, whereby PD-1/L1 blockade is reported to impressively extend survival rates in responders. Trials investigating either the synergistic effect of anti-angiogenesis and anti-PD-L1 or chemotherapy combined with anti-PD-L1 are promising. Based on these data we hypothesize benefit from combining immunotherapy by checkpoint inhibition with VEGF-directed treatment and chemotherapy induced increase of immunogenicity of tumor cells. This study investigates the incorporation of PD-L1 blockade by avelumab in the second line setting by combination with the actual best second-line chemotherapy regimen in metastatic gastric cancer patients (paclitaxel+ramucirumab). Methods: The RAP trial (AIO-STO-0218, registered at ClinicalTrials.gov) is a single arm multicenter phase II trial. A total of 59 patients with metastatic or locally advanced gastric or gastro-esophageal junction adenocarcinoma, ECOG 0–1, who progressed after having received first-line therapy with platinum and fluoropyrimidine doublet with or without anthracycline, docetaxel or trastuzumab within the last six months will receive avelumab and ramucirumab on day 1, 15 and paclitaxel on day 1, 8 and 15 of a 28-day cycle until disease progression (RECIST v1.1), intolerable toxicity, withdrawal of consent or at a maximum treatment of 1 year. The primary endpoint is the overall survival rate (OSR) at 6 months. Sample size calculation is based on a Simon 2-stage design with a one-sided alpha error of 10% and a power of 80%, an expected OSR at 6 months of ≥ 65% and a 0 hypothesis ≤ 50%. Secondary endpoints include OS, OSR at 12 months, PFS, safety and tolerability, duration of response. Ethics commission approved the study protocol in January 2019. Updated patient accrual will be presented. Clinical trial information: AIO-STO-0218.

TPS4150 Background: Ramucirumab is used for treatment of metastatic gastroesophageal adenocarcinoma after disease progression on first-line chemotherapy. Superior survival outcome is expected when combined with paclitaxel. However, many patients suffer from neuropathy after oxaliplatin-containing first-line chemotherapy and are unable to tolerate paclitaxel. Irinotecan has shown survival benefit as a single agent or in combination with other agents, but has not been used in combination with ramucirumab for treatment with gastroesophageal cancer. We hypothesize that this combination regimen of irinotecan plus ramucirumab administered as second-line treatment will be well-tolerated with improved outcomes similar to paclitaxel plus ramucirumab in patients with advanced gastroesophageal cancer. Circulating levels of angiogenic factors are correlatives of particular interest in this study. Methods: This is a multi-institutional, single-arm phase II clinical trial of ramucirumab and irinotecan. Primary objective of the study is to determine the progression-free survival in patients treated with this combination after disease progression on first-line chemotherapy. Secondary objectives are to determine other indices of efficacy including overall survival, time to progression, objective response rate, and clinical benefit rate; and to evaluate toxicity and tolerability. Patients with confirmed diagnosis of gastroesophageal adenocarcinoma with measurable disease are included. Patients are required of have disease progression during or within 4 months of first line chemotherapy. Key exclusion criteria include squamous histology; prior irinotecan or ramucirumab use; active brain metastases; or other contraindications to ramucirumab including recent history of gastrointestinal bleeding or perforation, thromboembolic event, and uncontrolled hypertension. Patients receive ramucirumab 8mg/kg with irinotecan 180mg/m2 IV every 14 days. We plan to enroll 40 patients which will provide 85% power at a 0.05 significance level to detect a median progression free survival time of 4 months compared to historic control of 2.5 months. 25% of patient accrual is complete as of February 2019. Clinical trial information: NCT03141034.

TPS4157 Background: C inhibits tyrosine kinases involved in tumor growth, angiogenesis, and immune regulation, including MET, VEGFR, and TAM kinases (Tyro3, AXL, MER). C is approved for treatment of aHCC after prior S based on improved overall survival (OS) vs placebo in the phase 3 CELESTIAL trial (Abou-Alfa NEJM 2018). Standard of care for first-line treatment of aHCC is tyrosine kinase inhibition with S or lenvatinib, and phase 3 trials of immune checkpoint inhibitors (ICIs) in first- and second- line aHCC are ongoing. C may promote an immune-permissive tumor environment, which could enhance response to ICIs. C is being evaluated in combination with the anti-PD-L1 antibody A in multiple tumor types including HCC in a phase 1 study; and dose, preliminary clinical activity, and safety have been established in aRCC (Agarwal Ann Oncol 2018). A in combination with bevacizumab, an anti-VEGF antibody, has shown preliminary clinical activity in first-line aHCC (Pishvaian Ann Oncol 2018). Here, we present the study design of a phase 3 trial of C+A vs S in pts with aHCC who have not received prior systemic therapy. Methods: This international, randomized, open-label phase 3 trial (NCT03755791) is evaluating the efficacy and safety of C+A vs S as first-line treatment for aHCC. Eligibility criteria include age ≥18 years, BCLC stage B or C, Child-Pugh A, ECOG PS 0 or 1, and measurable disease per RECIST 1.1. Patients are randomized 6:3:1 to an experimental arm of C (40 mg qd) + A (1200 mg infusion q3w), a control arm of S (400 mg bid), and an exploratory arm of C monotherapy (60 mg qd). 640 pts are planned at ~200 sites globally. Randomization is stratified by disease etiology (HBV [with or without HCV], HCV [without HBV], or other), region (Asia, other), and the presence of extrahepatic disease and/or macrovascular invasion (yes, no). OS and progression-free survival are coprimary endpoints and objective response rate is a secondary endpoint. Additional endpoints include safety, pharmacokinetics, and correlation of biomarker analyses with clinical outcomes. Enrollment in COSMIC-312 is ongoing. Clinical trial information: NCT03755791.

TPS4591 Background: Intravesical instillation of BCG is standard of care for patients (pts) with HR NMIBC. However, many pts have persistent/recurrent HR NMIBC after BCG induction and are at increased risk for progression to muscle-invasive disease. Interim data from the phase 2 KEYNOTE-057 study has shown that the PD-1 inhibitor pembro had promising efficacy in HR NMIBC as monotherapy. KEYNOTE-676 (NCT03711032) is a randomized, comparator-controlled, phase 3 trial to evaluate efficacy and safety of pembro plus BCG in pts with persistent/recurrent HR NMIBC after BCG induction therapy. Methods: Pts are randomly assigned 1:1 to continue BCG therapy alone or receive BCG plus pembro 200 mg every 3 weeks. Treatment is stratified by carcinoma in situ (CIS) histology (presence/absence), PD-L1 combined positive score (≥10/˂10), and timing of NMIBC persistence/recurrence (0 to ≤6, ˃6 to ≤12, or ˃12 to ≤24 mo). Pts are eligible if they are ≥18 years of age with histologically confirmed persistent/recurrent HR NMIBC of the bladder after adequate BCG induction therapy, have undergone cystoscopy/transurethral resection of bladder tumor within 12 weeks before randomization, have no concurrent extravesical disease, and have an ECOG PS score of 0-2. Responses are assessed by cystoscopy and blinded independent central review of urine cytology and biopsy (as applicable) every 12 weeks for years 1-2 and every 24 weeks for years 3-5 and by computed tomography urography every 18 months through year 5. Treatment will continue with pembro for up to 2 years and BCG for 3 years or until confirmed HR NMIBC persistence, recurrence, or disease progression, unacceptable toxicity, or pt/physician decision to withdraw. Primary end point is complete response rate in pts with CIS. Secondary end points are event-free survival (EFS), recurrence-free survival, overall survival, disease-specific survival, time to cystectomy, 12-month EFS rate in all pts, duration of response (DOR), 12-month DOR rate in pts with CR and safety and tolerability. Recruitment began in November 2018 and will continue until ~550 pts are enrolled. Clinical trial information: NCT03711032.
