Purpose Patients with metastatic colorectal cancer (mCRC) have limited benefit from the addition of bevacizumab to standard chemotherapy. However, a subset probably benefits substantially, highlighting an unmet clinical need for a biomarker of response to bevacizumab. Previously, we demonstrated that losses of chromosomes 5q34, 17q12, and 18q11.2-q12.1 had a significant correlation with progression-free survival (PFS) in patients with mCRC treated with bevacizumab in the CAIRO2 clinical trial but not in patients who did not receive bevacizumab in the CAIRO trial. This study was designed to validate these findings. Materials and Methods Primary mCRC samples were analyzed from two cohorts of patients who received bevacizumab as first-line treatment; 96 samples from the European multicenter study Angiopredict (APD) and 81 samples from the Italian multicenter study, MOMA. A third cohort of 90 samples from patients with mCRC who did not receive bevacizumab was analyzed. Copy number aberrations of tumor biopsy specimens were measured by shallow whole-genome sequencing and were correlated with PFS, overall survival (OS), and response. Results Loss of chromosome 18q11.2-q12.1 was associated with prolonged PFS most significantly in both the cohorts that received bevacizumab (APD: hazard ratio, 0.54; P = .01; PFS difference, 65 days; MOMA: hazard ratio, 0.55; P = .019; PFS difference, 49 days). A similar association was found for OS and overall response rate in these two cohorts, which became significant when combined with the CAIRO2 cohort. Median PFS in the cohort of patients with mCRC who did not receive bevacizumab and in the CAIRO cohort was similar to that of the APD, MOMA, and CAIRO2 patients without an 18q11.2-q12.1 loss. Conclusion We conclude that the loss of chromosome 18q11.2-q12.1 is consistently predictive for prolonged PFS in patients receiving bevacizumab. The predictive value of this loss is substantiated by a significant gain in OS and overall response rate.

Aim: We performed an updated meta-analysis to evaluate the efficacy and safety of lenvatinib in cancer patients. Materials & methods: Databases were searched to identify relevant trials. Data were extracted to evaluate overall survival, progression-free survival, overall response rate and grade ≥3 adverse events. Results: The pooled analysis demonstrated that lenvatinib significantly improved progression-free survival (hazard ratio: 0.43; 95% CI: 0.23–0.80; p = 0.008), overall survival (hazard ratio: 0.85; 95% CI: 0.75–0.97; p = 0.013) and overall response rate (relative risk: 6.89; 95% CI: 2.22–21.36; p = 0.001) compared with control therapy. However, the use of lenvatinib can increase the risk of severe infection. Conclusion: Lenvatinib-containing regimens are associated with better progression-free survival, overall survival and overall response rate, but can induce severe infection.

3022 Background: The selective targeting of tumors with monoclonal antibodies (mAb) has emerged as a new therapeutic approach in cancer therapy with the A33 glycoprotein being a promising target in colorectal cancer. Specific tumor localization and low toxicity of a humanised A33 specific mAb (huA33) has previously been demonstrated in patients with colorectal carcinoma. In the present study, we determined the safety and efficacy of the combination of huA33 and 5FU plus leucovorin and oxaliplatin (FOLFOX-4) in patients with metastatic colorectal cancer. Methods: Patients had to present with metastatic colorectal cancer with an expected survival of at least 4 months and no more than 2 different pre-treatment regimens. Patients were excluded if they had previously received oxaliplatin or huA33 mAb. Eligible patients received huA33 (10 mg/m2) by iv infusion weekly for 12 weeks (cycle 1). On study day 15, standard FOLFOX-4 chemotherapy was administered every 2 weeks for 10 weeks. Responding patients received a second cycle of weekly huA33 (10 mg/m2) and biweekly FOLFOX-4 chemotherapy. Results: A total of 19 patients (11 female, 8 male) with a median age of 60 years entered the study. 5 patients had received prior chemotherapy, 2 radiation therapy and 18 surgery. Toxicities observed were as expected for FOLFOX-4 treatment alone with hematological side effects to be most prominent and included (only G3 and G4) 1 anemia and 10 neutropenias. The addition of huA33 to FOLFOX-4 did not change the pattern of known non-hematological toxicities with a low rate (14%) of huA33 mAb associated allergic reactions. One sudden death occurred at cycle five that was neither therapy nor disease related. Within the 16 patients currently available for response assessment, the overall response rate was 38% with 1 CR, 5 PR and 5 disease stabilizations. Conclusion: The combination of FOLFOX-4 as standard chemotherapy for this cohort of patients in combination with the humanized A33 antibody did not increase toxicities and was well tolerated. The overall response rate of 38% is in the response range published so far for the FOLFOX-4 regimen in this setting and warrants further analysis in a larger cohort of patients. [Table: see text]

Background: The aim of this study was to compare the efficacy and hematologic toxicity of cetuximab combined with various types of chemotherapy regimens in patients with KRAS wild-type metastatic colorectal cancer (mCRC). Methods: The response rate, progression-free survival (PFS) and overall survival of the patients were analyzed. Results: In total, 45 patients were included in the study. The overall response rate for the combination of cetuximab and FOLFOX, FOLFIRI and CAPOX was 20, 46 and 30%, respectively, but the differences were not statistically significant. The median PFS for the three groups were 8, 6 and 3.5 months, respectively, but again these differences were not significant. All-grade leukopenia and anemia for the cetuximab plus FOLFOX group were significantly higher than for the other chemotherapy regimens. Conclusion: Our findings suggest that the combination of cetuximab and the three standard chemotherapy regimens resulted in the same outcomes in our patient population of mCRC, with higher hematologic toxicities among the FOLFOX subgroup.

Twenty consecutive patients who had biopsy proven metastatic colorectal cancer were treated with combination chemotherapy. The drug regimen (FVH), in a 4 week cycle, consisted of 5-fluorouracil (600 mg/m2 i.v. on days 1, 8, 15 and 22), vincristine (1.4 mg/m2 i.v. on day 4), and hydroxyurea (2400 mg/m2 p.o. on days 3, 10, 17 and 24). Three of the 18 evaluable patients achieved an objective tumor remission (2 CR and 1 PR) and 15 patients had stable disease. The overall response rate to FVH was therefore not superior to that achieved in patients who received 5-fluorouracil alone, and the overall survival in this study was comparable to that of other studies involving patients with metastatic colorectal cancer.

PURPOSE To determine the safety and preliminary efficacy of selective combination targeted therapy for BRAF V600E–mutant metastatic colorectal cancer (mCRC) in the safety lead-in phase of the open-label, randomized, three-arm, phase III BEACON Colorectal Cancer trial ( ClinicalTrials.gov identifier: NCT02928224; European Union Clinical Trials Register identifier: EudraCT2015-005805-35). PATIENTS AND METHODS Before initiation of the randomized portion of the BEACON Colorectal Cancer trial, 30 patients with BRAF V600E–mutant mCRC who had experienced treatment failure with one or two prior regimens were to be recruited to a safety lead-in of encorafenib 300 mg daily, binimetinib 45 mg twice daily, plus standard weekly cetuximab. The primary end point was safety, including the incidence of dose-limiting toxicities. Efficacy end points included overall response rate, progression-free survival, and overall survival. RESULTS Among the 30 treated patients, dose-limiting toxicities occurred in five patients and included serous retinopathy (n = 2), reversible decreased left ventricular ejection fraction (n = 1), and cetuximab-related infusion reactions (n = 2). The most common grade 3 or 4 adverse events were fatigue (13%), anemia (10%), increased creatine phosphokinase (10%), increased AST (10%), and urinary tract infections (10%). In 29 patients with BRAF V600E–mutant tumors (one patient had a non– BRAF V600E–mutant tumor and was not included in the efficacy analysis), the confirmed overall response rate was 48% (95% CI, 29.4% to 67.5%), median progression-free survival was 8.0 months (95% CI, 5.6 to 9.3 months), and median overall survival was 15.3 months (95% CI, 9.6 months to not reached), with median duration of follow-up of 18.2 months (range, 16.6 to 19.8 months). CONCLUSION In the safety lead-in, the safety and tolerability of the encorafenib, binimetinib, and cetuximab regimen is manageable and acceptable for initiation of the randomized portion of the study. The observed efficacy is promising compared with available therapies and, if confirmed in the randomized portion of the trial, could establish this regimen as a new standard of care for previously treated BRAF V600E–mutant mCRC.

4068 Background: Bevacizumab (BEV) is a monoclonal antibody that inhibits tumour angiogenesis by targeting VEGF. In a phase III trial (AVF2107g), BEV significantly improved overall (OS) and progression-free survival (PFS) when combined with first-line irinotecan plus bolus 5-fluorouracil (5-FU)/leucovorin (LV) (IFL) in patients with metastatic colorectal cancer (mCRC). A multicentre, open-label trial is being conducted to evaluate the efficacy and safety of first-line BEV in combination with irinotecan and infusional 5-FU (FOLFIRI), a widely used first-line chemotherapy (CT) regimen. Methods: Patients had to have: mCRC; no surgery within 28 days; no prior CT for metastatic disease; ECOG PS 0/1, adequate organ function; no CNS metastases. CT consisted of a minimum of six cycles of irinotecan plus infusional 5-FU/LV according to the classical FOLFIRI regimen; variations like the simplified FOLFIRI and the weekly regimen were also allowed. BEV 5mg/kg was given on day 1 with CT and then every 2 weeks until disease progression. Tumour assessments were performed every 3 months during the first 12 months and every 4 months thereafter. Safety was assessed at the time of CT administration and every 4 weeks thereafter. The primary objective was PFS; secondary objectives included safety, overall response rate, time to response, duration of response and OS. Results: A total of 209 patients were enrolled at 31 centres worldwide, between April and November 2005. An interim analysis showed that the safety profile of BEV plus FOLFIRI appeared to be similar to that reported for Avastin plus IFL. The 44% overall response rate and 90% disease control rate are at least equivalent to that reported in comparable trials. Additionally, the 6 months PFS estimate of 82% was superior to that reported in AVF2107. Mature PFS data will be presented. Conclusions: AVIRI is the largest clinical trial, to date, to report data for BEV in combination with FOLFIRI in first-line patients with mCRC. The safety profile appears consistent with that observed in other BEV trials in mCRC, while the preliminary efficacy data suggest that this regimen is as active as the bolus regimen.

Background Patients with locally advanced, recurrent or metastatic solitary fibrous tumour are often treated with bevacizumab and temozolomide based on the clinical efficacy reported in a case series of 14 patients. Given the rarity of solitary fibrous tumour, large trials are not feasible. We report the efficacy of this regimen based on a population-based analysis. Methods This was a population-based retrospective, multi-centre analysis using patient data from a provincial cancer registry and treatment database. Cases from June 2006 through October 2016 were identified for patients receiving bevacizumab and temozolomide for locally advanced, recurrent or metastatic solitary fibrous tumour or hemangiopericytoma, which is sometimes used to describe tumours arising from the meninges. The primary outcome was overall response rate. Secondary outcomes included time to response, progression free survival and overall survival estimated using the Kaplan–Meier method. Results Fourteen patients were identified: median age 59 (range 44–70), male 78.6%. Diagnoses were solitary fibrous tumour in 10 (71.4%) and hemangiopericytoma in four (28.6%), with metastatic disease in 10 (72.7%) patients. The most common primary sites were meninges in four (28.6%) and pelvis in three (21.4%) patients. The median follow-up was 15.5 months, with median treatment of four months. Overall response rate was 21.4% (no complete response, 3 partial response), with median time to response of four months. Median progression free survival, six-month progression free survival and overall survival were 17 months, 65.0%, and 45 months, respectively. Conclusions Efficacy of bevacizumab and temozolomide in solitary fibrous tumour appeared to be similar to that previously reported. Our findings confirmed that bevacizumab and temozolomide is an effective and tolerated treatment for this patient population.

PURPOSE Recurrent or metastatic adenoid cystic carcinoma (R/M ACC) is a malignant neoplasm of predominantly salivary gland origin for which effective therapies are lacking. We conducted a phase II trial evaluating the multitargeted tyrosine kinase inhibitor lenvatinib in patients with R/M ACC. PATIENTS AND METHODS This study was conducted with a two-stage minimax design. Patients with histologically confirmed R/M ACC of any primary site with radiographic and/or symptomatic progression were eligible. Any prior therapy was allowed except previous lenvatinib. Patients received lenvatinib 24 mg orally per day. The primary end point was overall response rate. Secondary end points were progression-free survival and safety. An exploratory analysis of how MYB expression and genomic alterations relate to outcomes was conducted. RESULTS Thirty-three patients were enrolled; 32 were evaluable for the primary end point. Five patients (15.6%) had a confirmed partial response, 24 patients (75%) had stable disease, two patients (6.3%) discontinued treatment as a result of toxicity before the first scan, and one patient (3.1%) had progression of disease as best response. Median progression-free survival time was 17.5 months (95% CI, 7.2 months to not reached), although only eight progression events were observed. Patients otherwise were removed for toxicity (n = 5), as a result of withdrawal of consent (n = 9), or at the treating physician’s discretion (n = 6). Twenty-three patients required at least one dose modification, and 18 of 32 patients discontinued lenvatinib for drug-related issues. The most common grade 3 or 4 adverse events were hypertension (n = 9; 28.1%) and oral pain (n = 3; 9.4%). Three grade 4 adverse events were observed (myocardial infarction, n = 1; posterior reversible encephalopathy syndrome, n = 1; and intracranial hemorrhage, n = 1). CONCLUSION This trial met the prespecified overall response rate primary end point, demonstrating antitumor activity with lenvatinib in R/M ACC patients. Toxicity was comparable to previous studies, requiring monitoring and management.

Abstract Purpose: Rituximab combined with chemotherapy has been recommended as first-line or second-line standard regimen in most subtypes of B-cell lymphoma in China by the 2004 National Comprehensive Cancer Network lymphoma therapy guideline. We have conducted a multicenter trial to evaluate the efficacy and safety of rituximab in combination with standard chemotherapy (CHOP) in patients with previously untreated or relapsed indolent and aggressive NHL. Methods: Patients received 4–8 cycles of rituximab plus CHOP every 21 days. For each cycle, rituximab (375mg/m2) was given on day 1 and CHOP started on day 3. CHOP consisted of cyclophosphamide 750mg/m2, doxorubicin 50mg/m2, and vincristine 1.4mg/m2 (maximum 2mg/dose) given intravenously on day 3, and oral prednisone 100mg on days 3–7. Results: A total of 221 patients were enrolled on the trial, 128 males and 93 females with a mean age of 49 years (range 10–83 years). The main lymphoma subtypes were small lymphocytic (15 patients, 7%), follicular (27 patients, 12%), and diffuse large B-cell (160 patients, 72%). In total, 56 patients had indolent NHL and 165 aggressive NHL. The overall response rate for all patients was 86% with 57% complete responses. In patients with indolent NHL the overall and complete response rates were 95% and 55% respectively. After a median 12 months follow up, progression-free survival in patients with indolent NHL was 88%±5% at 1 year and 83%±6% at 2 years. In the 160 patients with diffuse large B-cell lymphoma, the overall response rate was 88% with 61% complete responses, and after a mean follow-up of 6 months, predicted 1-year and 2-year progression-free survival were 88%±5% and 83%±7% respectively. Infusion-related adverse events occurred in 4% of patients, associated with the first infusion of rituximab. Subanalyses according to subtype, stage, IPI and other factors will be presented. Conclusion: Rituximab plus chemotherapy is an effective, well-tolerated treatment that achieves high response rates and long progression-free survival in both indolent and aggressive NHL.
