Dose Dense

4078 Background: Every 3 week (Q3W) COB has been shown to be highly active and non-inferior to FOLFOX+B in first-line mCRC. Phase II data suggest that dose-dense every 2 week (Q2W) COB may be significantly more active and better tolerated than Q3W COB. Methods: XELOXA-DVS was a phase III, open-label study of 435 patients with chemonaive mCRC who met standard eligibility criteria. Patients were randomized to Q3W: C 850 mg/m2 BID d1–14 + O 130 mg/m2 d1 + B 7.5 mg/kg d1 or Q2W: C 1500 mg/m2 BID d1–7 + O 85 mg/m2 d1 + B 5 mg/kg d1 for up to 72 weeks. Complete surgical resection was allowed using pre-defined criteria. The primary endpoint, progression-free survival (PFS), was estimated using the Kaplan- Meier method, while the hazard ratio and 95% CI were estimated using Cox regression analysis, based on the intent-to-treat population. No formal statistical testing was conducted. Results: The median PFS was 8.4 months (Q2W) and 9.7 months (Q3W) (hazard ratio [HR]=0.84; 95% CI=0.62–1.13). The median PFS (on-treatment) was 9.1 months and 10.2 months, respectively (HR=0.81). Of the 72 and 73 patients with disease progression (DP), the median time to DP was 9.4 and 10.8 months, respectively (HR=0.86). The objective response rates were 21.7% vs 29.4%, respectively (HR=1.05). Patients in the Q2W vs Q3W group experienced higher rates of grade 3/4 diarrhea (29% vs 24%), hand-foot syndrome (12% vs 8%), and treatment discontinuation rates (40% vs 20%), respectively. Other grade 3/4 toxicities (>5%, Q2W vs Q3W) included fatigue (13% vs 13%), dehydration (12% vs 10%), nausea (8% vs 9%), peripheral neuropathy (5% vs 9%), anorexia (5% vs 7%), and abdominal pain (5% vs 7%). Conclusions: At the dose and schedule used, dose-dense Q2W COB was not superior to standard Q3W COB. These data further confirm the activity and tolerability of Q3W COB. The activity and tolerability of a lower C dose Q2W, with more aggressive dose reduction, combined with B and O or irinotecan is currently being evaluated (X-BIO). [Table: see text]

1528 Background: Cytarabine liposome injection (CLI) maintains cytotoxic concentrations in the cerebral spinal fluid (CSF) for >14 days with a single 50 mg dose. This study compared patient benefit and safety of intrathecal CLI with methotrexate (MTX) or nonliposomal cytarabine (Cyt) against solid tumor neoplastic meningitis (STNM) and lymphomatous neoplastic meningitis (LNM), respectively. Methods: This multicenter, randomized, open-label, active-controlled study was powered to detect a 50% hazard ratio for progression-free survival (PFS; i.e., days from randomization to neurological progression or death) in STNM patients. STNM patients (n=103) were randomized to CLI or MTX and LNM patients (n=25) to CLI or Cyt. Patients had either histologically documented STNM or LNM confirmed by ventricular or lumbar CSF cytology or symptomatic meningeal tumor verified by magnetic resonance imaging or computed tomography. CLI treatment consisted of 6 Induction Cycles (2 weeks per cycle) and 4 Maintenance Cycles (4 weeks per cycle). Results: By per-protocol Cox regression analysis, CLI (STNM and LNM combined) was noninferior to MTX and Cyt combined (Control Group). The median PFS was 35 days and 43 days (p=0.7321), respectively; the hazard ratio (95% CI) was 0.98 (0.65, 1.46). CLI was also noninferior to MTX in the STNM group, where the hazard ratio was 0.94 (0.58; 1.53). In the LNM group, superiority of CLI over Cyt was demonstrated a hazard ratio of 0.12 (0.02, 0.77). Median PFS was 34 and 50 days, respectively. More LNM patients had complete response (clearance of tumor cells from CSF) with CLI (33.3%) than with Cyt (16.7%; p=0.3640). All patients experienced AEs; 48% and 60% of the patients in CLI and Control Group, respectively, experienced drug-related AEs. The incidence of serious AEs was 86% and 77%, respectively. Conclusions: These results demonstrate at least comparable patient benefit between CLI and control treatments for STNM and improved benefit for CLI in LNM patients. Intrathecal CLI provides patients with the added convenience of bimonthly treatment. [Table: see text]

e16108 Background: Cetuximab associated calcifications is a positive predictive factor in metastatic colorectal cancer (mCRC). In patients with glioblastoma, bevacizumab-induced calcifications are also related to a better prognosis. However, tumor calcifications are rarely recognized in mCRC patients treated with bevacizumab. This study was to investigate the correlation between clinical outcome and calcification in mCRC who received bevacizumab and chemotherapy as the first-line treatment. Methods: A single retrospective cohort study was conducted with all diagnosed mCRC cases who received bevacizumab and chemotherapy as the first-line therapy in our hospital from January 2016 to January 2019. Clinical variables were retrieved from medical records and tumor calcification were evaluated independently by radiologists on the basis of computed tomography scans. A univariate and multivariate COX regression analysis was performed to evaluate the association between calcification and outcome. Results: 159 patients with an average age of 59.0 years were included. Median follow-up was 29.6 months. Among all enrolled patients, 31 had tumor calcification [31/159 (19.5%)]. The median overall survival (OS) and progression-free survival (PFS) was significantly better in patients with calcification than those without calcification (28.0 vs. 24.9 months, p= 0.024; 12.0 vs. 10.0 months, p= 0.026). A higher objective response rate (61.3% vs. 50.0%) was also observed in calcification group. On multivariate analysis, tumor calcification was independently associated with OS (hazard ratio 1.799, 95% CI 1.002–3.230) and PFS (hazard ratio 1.609, 95% CI 1.013–2.557). Conclusions: Tumor calcification was independently associated with improved prognosis in colorectal cancer. It might be a potential prognostic marker.

Abstract Background The optimal chemotherapy regimen between temozolomide and procarbazine, lomustine, and vincristine (PCV) remains uncertain for W.H.O. grade 3 oligodendroglioma (Olig3) patients. We therefore investigated this question using national data. Methods Patients diagnosed with radiotherapy-treated 1p/19q-codeleted Olig3 between 2010-2018 were identified from the National Cancer Database. The OS associated with first-line single-agent temozolomide vs. multi-agent PCV was estimated by Kaplan-Meier techniques and evaluated by multivariable Cox regression. Results 1,596 radiotherapy-treated 1p/19q-codeleted Olig3 patients were identified: 88.6% (n=1,414) treated with temozolomide and 11.4% (n=182) with PCV (from 5.4% in 2010 to 12.0% in 2018) in the first-line setting. The median follow-up was 35.5 months (interquartile range [IQR] 20.7-60.6 months) with 63.3% of patients alive at time of analysis. There was a significant difference in unadjusted OS between temozolomide (5yr-OS 58.9%, 95%CI: 55.6-62.0) and PCV (5yr-OS 65.1%, 95%CI: 54.8-73.5; p=0.04). However, a significant OS difference between temozolomide and PCV was not observed in the Cox regression analysis adjusted by age and extent of resection (PCV vs. temozolomide HR 0.81, 95%CI: 0.59-1.11, p=0.18). PCV was more frequently used for younger Olig3s, but otherwise was not associated with patient’s insurance status or care setting. Conclusions In a national analysis of Olig3s, first-line PCV chemotherapy was associated with a slightly improved unadjusted short-term OS compared to temozolomide; but not following adjustment by patient age and extent of resection. There has been an increase in PCV utilization since 2010. These findings provide preliminary data while we await the definitive results from the CODEL trial.

Purpose To determine whether irinotecan plus oxaliplatin (IROX) is superior to irinotecan alone in patients with metastatic colorectal cancer (CRC) previously treated with single-agent fluoropyrimidines. Patients and Methods A phase III, randomized, open-label, multicenter study of patients with metastatic or recurrent CRC that had progressed or recurred during or after adjuvant or first-line fluoropyrimidines (fluorouracil/leucovorin or capecitabine, the latter only for metastatic CRC). Patients received IROX (irinotecan 200 mg/m2 plus oxaliplatin 85 mg/m2) or irinotecan alone (350 mg/m2) every 3 weeks. Results At the data cutoff (when 447 of 628 randomly assigned patients had died), median overall survival was 13.4 months (95% CI, 12.4 to 14.7 months) and 11.1 month (95% CI, 10.0 to 12.7 months) in the IROX and irinotecan groups, respectively (hazard ratio = 0.78; 95% CI, 0.65 to 0.94; P = .0072). Overall response rate (22% v 7%, respectively; P < .0001), median time to progression (5.3 v 2.8 months, respectively; P < .0001), and improvement in tumor-related symptoms (32% v 19%, respectively; P = .0072) were also improved with IROX as compared with irinotecan. With the exception of granulocytopenia (25% v 13%), diarrhea (28% v 23%), and sensory disturbances (5% v 0%), grade 3 to 4 toxicities were comparable between the IROX and irinotecan groups, respectively. Conclusion IROX is an effective treatment for metastatic CRC that has progressed after first-line fluoropyrimidine therapy. IROX improves efficacy compared with irinotecan alone, providing an additional option in the postadjuvant or second-line treatment setting for patients who experience treatment failure with single-agent fluoropyrimidine therapy.

PURPOSE: To study how adding oxaliplatin (l-OHP) to chronomodulated fluorouracil (5-FU)–leucovorin (LV) affected the objective response rate, as first-line treatment of metastatic colorectal cancer. PATIENTS AND METHODS: Two hundred patients from 15 institutions in four countries were randomly assigned to receive a 5-day course of chronomodulated 5-FU and LV (700 and 300 mg/m2/d, respectively; peak delivery rate at 0400 hours) with or without l-OHP on the first day of each course (125 mg/m2, as a 6-hour infusion). Each course was repeated every 21 days. Response was assessed by extramural review of computed tomography scans. RESULTS: Grade 3 to 4 toxicity from 5-FU–LV occurred in ≤ 5% of the patients (≤ 1% of the courses). Grade 3 to 4 diarrhea occurred in 43% of the patients given l-OHP (10% of the courses), and less than 2% of the patients had severe hematotoxicity. Thirteen percent of the patients had moderate functional impairment from peripheral sensory neuropathy. Sixteen percent of the patients receiving 5-FU–LV had an objective response (95% confidence interval [CI], 9% to 24%), compared with 53% of those receiving additional l-OHP (95% CI, 42% to 63%) (P < .001). The median progression-free survival time was 6.1 months with 5-FU–LV (range, 4.1 to 7.4 months) and 8.7 months (7.4 to 9.2 months) with l-OHP and 5-FU–LV (P = .048). Median survival times were 19.9 and 19.4 months, respectively. CONCLUSION: By chronomodulating 5-FU–LV, we were able to add l-OHP without compromising dose-intensities. l-OHP significantly improved the antitumor efficacy of this regimen.

LBA4017 Background: The aim was to establish the potential use of the third generation platinum compound, oxaliplatin (O) & the oral fluoropyrimidine capecitabine (X) in untreated patients (pts) with advanced OG cancer. Methods: After stratification for PS and extent of disease, pts with histologically confirmed adenocarcinoma, squamous or undifferentiated carcinoma of the oesophagus, oesophago-gastric junction or stomach were randomised, in a 2 x 2 design, to 1 of 4 regimens; epirubicin, cisplatin, fluorouracil (ECF), EOF, ECX or EOX. Doses E 50 mg/m2, C 60 mg/m2 & O 130 mg/m2 IV 3 weekly; F 200 mg/m2 IV daily & X 625 mg/m2 twice daily PO continuously; for 8 cycles. The primary endpoint was overall survival. With 1000 pts (250 per arm) the study had 80% power to demonstrate non-inferiority of X over F and also O over C if the upper limit of the HR 95% CI excluded 1.23 (α = 0.05) in the per protocol population. Analysis was performed using the logrank test and Cox regression analysis. Results: 1002 pts were randomised from 61 centres. Demographics were balanced, 89% were PS 0–1, 77% metastatic, median age 63 (range 22–83), 81% were male and 40% gastric primaries. Histology: adenocarcinoma in 88% and 52% poorly differentiated. 11 pts were ineligible and 27 pts were withdrawn before treatment commenced. Median follow up was 17.1 months and 850 events have occurred. There were no significant differences in response rates comparing ECF to, EOF, ECX and EOX (41%, 42%, 46%, and 48% respectively); grade 3–4 non haematological toxicity 36%, 42%, 33% and 45%; and grade 3–4 neutropaenia 42%, 30% (p = 0.008), 51% (p = 0.043) and 28% (p = 0.001) respectively. Conclusions: Capecitabine may replace 5FU and Oxaliplatin may replace Cisplatin in triplet regimens used for the treatment of advanced OG cancer. [Table: see text] [Table: see text]

LBA7007 Background: NOV-002 is a formulation of disodium glutathione disulfide (GSSG). GSSG is a naturally occurring substance that functions as a component of the glutathione (GSH) pathway, vital to the regulation of the intracellular redox state. A key function of the GSH/GSSG redox couple is to dynamically regulate protein functions, including cell signaling pathways, through the reversible formation of mixed disulfides between protein cysteines and GSH (S-glutathionylation). Based on positive results from a randomized, phase I/II study of carboplatin and paclitaxel (CP) with or without NOV-002, as well as positive results from 2 ex-U.S. phase II studies with cisplatin-based chemotherapy, an international phase III randomized trial was launched. Methods: Patients with advanced NSCLC (stages wet IIIB and IV, inclusive of all histological subtypes) were eligible if they had a PS of 0-1 and adequate end-organ function. Patients with CNS metastases were excluded. Eligible patients were randomized to C (AUC 6), P (200 mg/m2), and NOV-002 (Group A) or C and P alone (Group B). NOV-002 was administered as two-60 mg IV boluses on day -1 of cycle 1 and as one IV bolus on day 1 of each cycle, followed by daily 60-mg subcutaneous injections. A total of 725 events were required to detect a difference in overall survival (OS) from 10.0 to 12.5 months with 85% power and a two-sided significance level of 0.05. No interim analysis was performed. Results: From 11/06 until 9/09, 903 patients were randomized, with target enrollment reached in March 2008. Patient characteristics for Groups A and B were as follows: stage IV (91.5/90.8%), PS 1 (76.6/72.6%), male (69.9/72.4%), never smoker (22.3/19.1%) median age (59.6/59.5), and histology (adenocarcinoma [40.0/36.8%] squamous [41.2/40.8%]). The median overall survival for Groups A and B was 10.2/10.8 months (p = 0.375), median progression-free survival was 5.3/5.6 months, objective response rate was 26.6/26.0% and 54/53% of patients completed at least six cycles of chemotherapy. Major toxicities for Groups A and B included grade 3/4 neutropenia (29.7/26.3%), febrile neutropenia (2.2/1.8%), grade 3/4 thrombocytopenia (3.8/2.9%), and grade 3/4 neuropathy (2.9/2.4%). Adverse events resulting in death in Groups A and B were reported in 5.6 and 3.1%, respectively. Conclusions: The addition of NOV-002 to CP does not improve overall survival in patients with advanced NSCLC. NOV002 does not appear to add to the overall toxicity of chemotherapy. [Table: see text]

TPS791 Background: The potent TLR-9 agonist MGN1703, a synthetic DNA-based immunomodulator, was compared to placebo in metastatic colorectal cancer (mCRC) patients with disease control after standard induction chemotherapy +/- bevacizumab in the phase II IMPACT trial and showed a superior effect with a hazard ratio for the primary endpoint PFS on maintenance of 0.55 (p=0.041) by local investigator assessment and 0.56 (p=0.070) by independent radiological review. In the MGN1703 arm 3 objective responses were observed, two of them appearing as late as 9 months after the start of treatment. At time of study closure 4 MGN1703 patients were still without progressive disease and continued treatment by self-administration in a compassionate use setting. Exploratory Cox regression and ROC analyses suggested a potential predictive role at baseline for normal CEA, objective response to prior chemotherapy and presence of activated NKT-cells. Methods: The pivotal IMPALA study has been designed to confirm these data and started to enroll patients with smaller tumor burden after a good response to chemotherapy, as best candidates to receive a maintenance treatment with immunotherapy. IMPALA is a randomized, international, multicenter, open-label phase III trial that will include 540 patients from 120 centers with the collaboration of the AIO, TTD, and GERCOR cooperative groups and is currently recruiting patients. In this study mCRC patients with an objective tumor response following any first line induction therapy will be randomized to MGN1703 monotherapy maintenance or local standard of care. At time of relapse, patients will reintroduce the induction treatment whenever feasible, with those in the experimental arm continuing to receive MGN1703 in the weeks without chemotherapy. Patients will also be stratified by CEA level and activated NKT at baseline. The primary endpoint of the study will be overall survival. Secondary endpoints include PFS, response rates, safety, and QoL in selected centers. All patients will be evaluated for cytokines and chemokines in serum and the activation status of various immune cell populations. Clinical trial information: NCT02077868.

351 Background: FOLFIRINOX is an approved regimen for metastatic pancreatic cancer (mPC). We performed a modification in FOLFIRINOX schedule, using nab-paclitaxel (nab-p) to obtain two regimens that could be as effective and less toxic than the original triplet. NabucCO study was a randomized phase II trial to assess activity and toxicity of nab-p instead of either oxaliplatin (Nab-FOLFIRI) or irinotecan (Nab-FOLFOX) in first line setting. Previous dose–finding NabucCO study defined that maximum tolerated dose of nab-p with FOLFIRI is 120 mg/m2, and with FOLFOX is 160 mg/m2. Methods: The study was a 1:1 parallel arm, open label, not comparative one to assess overall response rate (ORR) of Nab-FOLFIRI and Nab-FOLFOX as primary end-point. Patients (pts) with PS 0-1, untreated for mPC were randomized to receive leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2, irinotecan 180 mg/m2 plus nab-p 120 mg/m2 (arm A) or leucovorin 400 mg/m2, 5FU bolus 400 mg/m2, 5FU 48h ci 2400 mg/m2 and oxaliplatin 85 mg/m2 iv plus nab-p 160 mg/m2 (arm B) every 2 weeks for up to 12 cycles. Secondary end points were clinical benefit rate (CBR), progression free survival (PFS), overall survival (OS), and safety. Results: From November 2015 to January 2017, 84 pts were treated (42 for each arm). Median age was 60 years (29-65) in arm A and 64 years (47-64) in arm B. The ORR was 31 % for both schedules, with a CBR of 69% and 71%, respectively. At a median follow-up of 11.4 months for arm A and 14.5 months for arm B (censored on august, 31th 2017), 1-year survival is 41% and 50%, respectively. For Nab-FOLFIRI PFS and mOS were 6 months (90% CI: 4.9-8.0) and 13.2 months (90% CI: 8.3-14.8), while in Nab-FOLFOX were 5.6 months (90% CI:4.9-7.2) and 10.8 months (90% CI: 8.4-12.8). Grade ≥3 toxicities in arm A were neutropenia (19%) and febrile neutropenia (12%). In arm B, main grade ≥3 toxicities were neutropenia (29%), fatigue (14%), peripheral neuropathy (7%). No toxic death were registered. Conclusions: Nab-FOLFIRI and Nab–FOLFOX demonstrated a similar activity to FOLFIRINOX, with better safety profile in terms of neutropenia, fatigue and neuropathy. These results could justify a future phase III evaluation. Clinical trial information: NCT02109341.

516 Background: GAIN-2 (NCT01690702) compared efficacy and safety of intense, dose-dense epirubicin, nab-paclitaxel, and cyclophosphamide (iddEnPC) vs dose-dense, dose-tailored epirubicin/ cyclophosphamide followed by dose-dense, dose-tailored docetaxel (dtEC-dtD) as adjuvant or neoadjuvant CT for node-positive or high risk node-negative EBC. Here, we report safety results and interim analysis (IA) of the primary endpoint iDFS. Methods: Pts (luminal A ≥N2; luminal B N+; HER2+ and TNBC) were randomized between iddEnPC (E 150 mg/m2, nP 330 mg/m2, C 2000 mg/m2, all q2w x 3) or dtEC-dtD (dtEC q2w x 4 followed after 1 week rest by dtD q2w x 4). Primary objective was to compare iDFS. 797 events are needed to detect a hazard ratio of 0.819 with a 2-sided log-rank-test with 80% power and α=0.05. The IA of iDFS was planned after 50% of the events have occurred. Safety and compliance were secondary objectives. Results: Between 10/2012 and 09/2018, 2887 pts were randomized and 2857 started treatment (iddEnPC 1429; dtEC-dtD 1428). Median age was 51 (range 18-75) years. Overall, 18.1% were luminal A, 31.5% luminal B/HER2-, 18.8% hormone-receptor (HR)+/HER2+, 8.5% HR-/HER2+ and 23.2% TNBC. Overall, 88.1% of pts completed all treatment in both arms. 66.8% with iddEnPC vs 58.8% with dtEC-dtD delayed CT dose (p<0.001). Grade 3-4 non-hematological adverse events (AEs) were more frequent with iddEnPC (iddEnPC 50.8% vs dtEC-dtD 45.1%, p=0.002). Grade 3-4 leukopenia, neutropenia, febrile neutropenia, arthralgia, and peripheral sensory neuropathy were significantly higher with iddEnPC. There were 1464 serious AEs (iddEnPC 870 vs dtEC-dtD 594) and 26 (9 vs 17) predefined AEs of special interest (anaphylaxis, any AE affecting cranial nerves, macula edema). Two deaths occurred during dtEC-dtD. After a median follow-up of 45.8 months, there was no difference in iDFS between arms (log-rank p=0.9102, hazard ratio iddEnPC vs dtEC-dtD 1.01, 95% CI 0.83-1.23). Conclusions: No new safety concerns were observed. Use of both iddEnPC and dtEC-dtD appears feasible in the (neo)adjuvant treatment of high risk EBC. Clinical trial information: NCT01690702 .
