4516 Background: The ESPAC-4 trial demonstrated that adjuvant GEM/CAP for pancreatic cancer significantly improved survival compared to GEM monotherapy. The aim of this study is to evaluate the long-term outcomes in the ESPAC-4 trial. Methods: Patients with pancreatic ductal adenocarcinoma were randomized within 12 weeks of surgery (stratified for R0/R1 resection margin status and country) to have either six 4-week cycles of IV GEM alone or GEM with oral CAP. The primary endpoint was five-year survival; secondary endpoints were toxicity and relapse free survival. 722 patients (480 expected events), 361 in each arm, were needed to detect a 10% difference in 2-year survival rates with 90% power (log-rank test with 5% two-sided alpha). Results: Between Nov 10 2008 and Sep 11 2014, 732 patients were randomized with 730 included in the full analysis set (366 GEM, 364 GEM/CAP). Median age was 65 years, 57% were men. WHO performance status was 0, 1 or 2 in 42% 55% and 3% respectively. Postoperative median CA19-9 was 19 kU/L. Median maximum tumor size was 30 mm, 61% were R1 resections, 80% were node positive and 40% were poorly differentiated. The data freeze was on 24 February 2020; median follow up was 60 months with 531 overall deaths, 280 in GEM, and 251 in GEM/CAP. Median (95% CI) survival (months) for patients treated with GEM/CAP was 27.7 23.3 – 31.2) and 26.0 (22.7 – 28.4) for GEM. Five-year (95% CI) survival rates were 20 (16 – 25) % for GEM and 28 (23 – 33) % for GEM/CAP. Stratified log-rank analysis revealed an HR=0.84 [95% CI, 0.70 – 0.99]; χ2 (1) = 3.87, P=0.049. 70 out of 366 GEM patients in the safety set reported 101 grade 3/4 serious adverse events, while 65 out of 359 GEM/CAP patients reported 97 grade 3/4 serious adverse events ( P=0.724). Conclusions: Adjuvant GEM/CAP for pancreatic cancer had a statistically significant improvement in survival compared to GEM monotherapy. Clinical trial information: 96397434 .

LBA4006 Background: The ESPAC-3 trial compared adjuvant GEM with 5-fluorouracil/folinic acid for resected pancreatic cancer. GEM is the standard of care based on similar survival and less toxicity. ESPAC-4 aimed to determine whether combination chemotherapy with GEM/CAP improved survival compared to GEM monotherapy. Methods: Patients with pancreatic ductal adenocarcinoma were randomized within 12 weeks of surgery (stratified for R0/R1 resection margin status and country) to have either six 4 week cycles of IV GEM alone or GEM with oral CAP. The primary endpoint was overall survival; secondary endpoints were toxicity, relapse free survival, 2 and 5 year survival and quality of life. 722 patients (480 expected events), 361 in each arm, were needed to detect a 10% difference in 2 year survival rates with 90% power (log-rank test with 5% two-sided alpha). Results: Between Nov 10 2008 and Sep 11 2014, 732 patients were randomized with 730 included in the full analysis set (366 GEM, 364 GEM/CAP). Median age was 65 years, 57% were men. WHO performance status was 0, 1 or 2 in 42% 55% and 3% respectively. Postoperative median CA19-9 was 19 kU/L. Median maximum tumor size was 30 mm, 60% were R1 resections, 80% were node positive and 40% were poorly differentiated. On Dec 11 2015 the Independent Trial Steering Committee requested that the trial proceed to full analysis. The data freeze was on March 2 2016. Median survival (months) for patients treated with GEM/CAP was 28.0 (95% CI, 23.5 – 31.5) and 25.5 (22.7 – 27.9) for GEM. Stratified log-rank analysis revealed an HR=0.82 [95% CI, 0.68 – 0.98]; χ2 (1) = 4.61, P=0.032. 196 out of 366 GEM patients in the safety set reported 481 grade 3/4 adverse events, while 226 out of 359 GEM/CAP patients reported 608 grade 3/4 adverse events ( P=0.242). Conclusions: Adjuvant GEM/CAP for pancreatic cancer had a statistically significant improvement in survival compared to GEM monotherapy. Clinical trial information: ISRCTN96397434.

Abstract BackgroundAccording to the NAPOLI-1 trial, nanoliposomal irinotecan (nal-IRI) plus 5-fluorouracil/leucovorin (5-FU/LV) showed improved overall survival compared to fluorouracil alone for patients with metastatic pancreatic cancer who previously treated gemcitabine-based therapy. In that trial, Asian patients had frequent dose modification due to hematological toxicity. There has been limited information on the clinical benefit and toxicity of this regimen in a real-world setting. Herein, we assessed real-world experience of nal-IRI plus 5-FU/LV in patients with advanced pancreatic cancer after gemcitabine failure.MethodsWe conducted a single institution retrospective analysis of response, survival and safety in patients who had been treated with nal-IRI with 5-FU/LV. Patients with metastatic pancreatic ductal adenocarcinoma previously treated with gemcitabine-based therapy received nal-IRI (80mg/m2) with 5-FU/LV every 2 weeks. ResultsFifty-one patients received nal-IRI plus 5-FU/LV between January 2015 and December 2020. The median age was 67 years, and males were 58.8%. A total of 40 (78.4%) and 11 (21.6%) patients had received one and two lines of prior chemotherapy before enrollment, respectively. Median progression-free survival was 2.8 months (95% confidence interval [CI] 1.8-3.7) and median overall survival was 7.0 months (95% CI 6.0-7.9). Chemotherapy doses were reduced or delayed in 33 (64.7%) patients during the first 6 weeks and median relative dose intensity was 0.87. Thirty-six (70.6%) patients experienced any grade 3 or 4 adverse events. Most common grade 3 or 4 adverse event was neutropenia (58.8%) and most non-hematologic adverse events were under grade 2. Since the start of first-line chemotherapy, median overall survival was 16.3 months (95% CI 14.1-18.4).ConclusionsNal-IRI plus 5-FU/LV seems to be effective, with manageable toxicities, after gemcitabine-based treatment in patients with metastatic pancreatic ductal adenocarcinoma.

LBA4505 Background: Adjuvant 5-FU/FA (ESPAC-1 trial) and GEM (CONKO-001 trial) provide improved survival for patients with resected pancreatic cancer compared to no chemotherapy. The aim of the ESPAC-3 (v2) trial was to compare 5FU/FA vs GEM to identify if either adjuvant chemotherapy was associated with a significantly better survival. Methods: Patients with an R0/R1 resection for pancreatic ductal adenocarcinoma were randomized (stratified for resection margin status and country) <8 weeks of surgery to receive either 5FU/FA (FA, 20 mg/m2, iv bolus injection followed by 5-FU, 425 mg/m2, iv bolus injection given 1–5d every 28 days) or GEM (1,000mg/m2 iv infusion 1d, 8d and 15d every 4 weeks) for 6 months. The primary outcome measure was overall survival; the secondary measures were toxicity, progression free survival and quality of life. 1,030 patients were needed to detect a 10% difference in 2-year survival rates with 90% power. Results: 1,088 patients from 16 countries were randomized from July 2000 to Jan 2007 (5FU/FA = 551, GEM = 537). Median (range) age was 63 (31–85) years; 598 (55%) were men. Median tumor size was 30 (20–350) mm; 384 (35%) were R1 resections; 777 (72%) were node positive; and 263 (25%) were poorly differentiated tumors. Final analysis was carried out on an intention to treat basis with a minimum of 2 years follow-up after 753 (69%) patients had died. Median (IQR) follow-up of 335 alive patients was 34.2 (27.1–43.4) months, equal across treatment groups. Median survival from resection of patients treated with 5FU/FA was 23.0 (95% CI: 21.1, 25.0) months and for patients treated with GEM this was 23.6 (95%CI: 21.4, 26.4) months. Log-rank analysis revealed no statistically significant difference in survival estimates between the treatment groups (c2LR=0.7, p=0.39, HRGEM=0.94 (95%CI: 0.81, 1.08)). There was no significant difference in the effect of treatment across subgroups according to R status (test of heterogeneity c21=0.3, p=0.56). Conclusions: This is the largest adjuvant trial ever conducted for pancreatic ductal adenocarcinoma and showed no significant difference in survival between adjuvant 5FU/FA and adjuvant GEM.

Anaplastic pancreatic cancer (APC) is a rare undifferentiated variant of pancreatic ductal adenocarcinoma with poor overall survival (OS). The aim of this study was to evaluate the clinical outcomes of APC compared with differentiated pancreatic ductal adenocarcinoma. We conducted a retrospective review of all patients treated at the Mayo Clinic with pathologically confirmed APC from 1987 to 2011. After matching with control subjects with pancreatic ductal adenocarcinoma, OS was evaluated using Kaplan-Meier estimates and log-rank test. Sixteen patients were identified with APC (56.3% male, median age 57 years). Ten patients underwent exploration of whom eight underwent pancreatectomy. Perioperative morbidity was 60 per cent with no mortality. The median OS was 12.8 months. However, patients with APC who underwent resection had longer OS compared with those who were not resected, 34.1 versus 3.3 months ( P = 0.001). After matching age, sex, tumor stage, and year of operation, the median OS was similar between patients with APC and those with ductal adenocarcinoma treated with pancreatic resection, 44.1 versus 39.9 months, ( P = 0.763). Overall survival for APC is poor; however, when resected, survival is similar to differentiated pancreatic ductal adenocarcinoma.

Abstract The addition of rituximab (R) therapy significantly improves PFS in patients with relapsedl/refractory disease responding after CHOP as well as responders after R-CHOP induction (van Oers, 2005). The aim of this study was to assess, in patients with previously untreated indolent NHL, the safety, efficacy and PK of additional R therapy in responders to R-CHOP induction. Between 10/01 and 08/06, 102 patients aged 28–84 (mean 57 yr) yrs with Ann Arbor Stage III (28.4%) or IV (71.6%) indolent NHL were treated on this Phase II single-arm, open-label, multi-center, community-based trial. Baseline LDH and β2 microglobulin were above normal in 20.6% and 66.3% of patients, respectively. Treatment consisted of 6 cycles of R-CHOP (cyclophosphamide 750 mg/m2, vincristine 1.4 mg/m2, and doxorubicin 50 mg/m2 all IV on Day 1 of each 21-day cycle; prednisone 100 mg/d po Days 1–5; and R 375 mg/m2 IV 2–3 days prior to first dose of CHOP and thereafter on Day 1 of each cycle). Patients with ongoing response (CR/CRu or PR) received R 375 mg/m2 weekly x 4, repeated every 6 months x 2 yrs, for a total of up to 16 R doses, within 28 days after completion of R-CHOP. Median follow-up was 39 mos. ORR after R-CHOP was 86.3% (95% CI: 78.3, 92.1), with CR/CRu 48% (95% CI: 38.0, 58.2). As measured from initiation of R-CHOP, PFS at 2 and 3 yrs was 75.2% (95% CI: 64.0, 83.3) and 67.3% (95% CI: 54.6, 77.2), respectively. OS at 2 and 3 yrs was 92.9% (95% CI: 85.7, 96.6) and 89.4% (95% CI: 81.2, 94.2), respectively. Infusion-related toxicity with R given after R-CHOP was less frequent than seen with R-CHOP in this study. The overall incidence of serious adverse events during R therapy given after R-CHOP was 8.5%, including 3 NCI-CTC grade 3/4 events: viral encephalitis (n=1), patellar fracture (n=1) & development of colon cancer (n=1). Serum R concentrations were collected over serial timepoints from 12 patients. Both pre- and end of infusion serum R concentrations were similar across cycles 2–4 of R therapy given after R-CHOP. R concentration was higher just prior to infusion of the first R dose given after R-CHOP due to residual concentration from the R-CHOP treatment. Concentrations were very low (< 10 ug/mL) just prior to initiation of the subsequent R cycles. During R therapy given after R-CHOP, serum R concentrations were similar to those previously reported during R monotherapy treatment (Berinstein, 1998). In summary, this study demonstrated that R therapy given after R-CHOP to be generally well-tolerated, and associated with 75.2% PFS and 92.9% OS at 2 yrs, and 67.3% PFS and 89.4% OS at 3 yrs. Moreover, the current study demonstrates that PK data from R induction can be extrapolated to R given after R-CHOP. The benefit of adding additional R therapy to responders to R-chemotherapy will be addressed in the analysis of the ongoing Phase III PRIMA study, wherein patients with advanced follicular lymphoma who respond to R-chemotherapy induction are randomized to receive further R therapy vs. observation.

Abstract Introduction The combination of lenalidomide and rituximab is an active treatment for patients (pts) with relapsed Chronic Lymphocytic Leukemia (CLL), with 66% Overall Response Rate (ORR) and a median Progression Free Survival (PFS) of 17.4 months (JCO 2013). We therefore sought to evaluate its efficacy and tolerability in untreated pts. Methods Twenty-five pts with untreated CLL have been enrolled. Rituximab (375 mg/m2 intravenously) was administered weekly during cycle 1 and on day 1 of cycles 3 to 12. Lenalidomide was started on day 9 of cycle 1 at 10 mg orally and administered daily continuously. Each cycle was 28 days. Rituximab was administered for 12 cycles; lenalidomide could continue indefinitely. Response was assessed every 3 cycles by 2008 NCI-WG criteria. Treatment-related toxicity was assessed using Common Terminology Criteria for Adverse Events (version 3.0). The primary end point of this study was ORR. Secondary objectives included PFS and Overall Survival (OS). PFS and OS were calculated using Kaplan-Meier estimates and compared using the log-rank test. Categorical variables were compared using Fisher's exact test (two tailed). Differences were considered significant if p≤.05. Results Baseline characteristics of the 25 pts are shown in Table 1. Twenty-four pts are evaluable for toxicity (one pt was taken off study after only 7 days due to the diagnosis of widely metastatic pancreatic cancer) and 20 for response (2 pts too early, 3 pts early discontinuation). So far 5 pts received 1 cycle, 1 pt received 2 cycles, 6 pts received 3 cycles, 5 received up to 6 cycles and 8 received 12 or more cycles of therapy. ORR by 2008 NCI-WG criteria is 85%, including 2 (10%) complete remission (CR) and 15 (75%) partial remissions (PR). No significant association between ORR and baseline characteristics was observed. At the latest follow-up, the median dose of lenalidomide was 5 (2.5-10) mg and 14 (56%) pts needed at least one interruption because of toxicity. Grade 3-4 toxicities are summarized in Table 2. No episodes of grade 3-4 tumor flare were observed and 7 (29%) pts experienced a grade 1 or 2 tumor flare. Eight (32%) pts have so far discontinued treatment: 1 because of metastatic pancreatic cancer diagnosed after only 1 week on study, 2 because of progressive disease (after 4 months and 13 months), and 5 because of toxicity (skin rash in 3 pts, a deep venous thrombosis in 1 pt, and persistent neutropenia in 1 pt). Two of the 5 pts who discontinued treatment have required subsequent therapy. Twenty-four pts are alive, 1 pt died of metastatic pancreatic cancer after treatment discontinuation. At a median follow-up of 9 (1-17) months, median PFS and median OS have not been reached. Conclusions Our initial experience with the combination of lenalidomide and rituximab as front-line treatment of CLL indicates that this combination is tolerated by the majority of pts and responses are seen in 85% of them. Enrolment in this study is ongoing. Disclosures: O'Brien: CELGENE: Consultancy. Ferrajoli:CELGENE: Research Funding.

3534 Background: In a phase III pivotal trial in patients (pts) with metastatic colorectal cancer (mCRC), bevacizumab (BEV) increased overall survival by 30% when added to first-line IFL chemotherapy (CT). Safety data from controlled BEV trials have been described, and indicate that certain serious adverse events (SAE), primarily gastrointestinal (GI) perforations and arterial thromboembolic events (TE) occurred more often in pts who received CT with BEV than those who received CT alone. First BEAT was opened to evaluate safety events of BEV in a broader pt population using a variety of CT regimens. Methods: First BEAT started in June 2004 and aims to enrol up to 2000 mCRC pts in 41 countries. Eligible pts starting with first-line CT (physician’s choice) are treated until progression with BEV (5mg/kg q2w [5FU based CT] or 7.5mg/kg q3w [capecitabine based CT]). SAEs include deaths, new and prolonged hospitalizations, life-threatening as well as medically significant events and are reported within 24 hours. There BEV-relatedness is assessed by investigators. Results: By Dec 20, 2005, 1915 pts had been enrolled in 40 countries. 1603/1915 pts (male 58%; median age 59 years [29% were > 65 years]; PS 0–1 99%) had baseline data available for analyses. Median follow-up was 6.7 months (mean 7.3); 1509 pts had been followed-up for >60 days. The most common first-line CT regimens used with BEV were FOLFOX (28%), CAPOX (17%), FOLFIRI (25%) and capecitabine (8%). Among the 1603 pts that had started treatment with BEV, 638 SAEs were reported in 394 pts (25%). 60-day mortality was 2.4%. The most common SAE were diarrhoea 2.7% and pyrexia 2.2% and were usually not attributed as related to BEV. Related SAEs were reported in 132 (8%) pts. venous TE 1.7%, pulmonary embolism 1.1%, bleeding 1.0%, GI perforation 0.9%, arterial TE 0.8%, hypertension 0.5% wound healing complications 0.3% were usually classified as related SAEs. Conclusions: In this ongoing, large community-based study, the safety profile of BEV in first line mCRC pts receiving a variety of CT regimens, namely FOLFOX, CAPOX, FOLFIRI and capecitabine, appears consistent with that observed in large phase III randomised studies. Updated safety data, including grade 3/4 CTC toxicities, will be presented. [Table: see text]

5500 Background: IC is associated with lower distant failure (DF) rates in SCCHN but an improvement in overall survival (OS) has not been validated. The goal of this trial was to determine whether IC prior to chemoradiotherapy (CRT) improves survival compared to CRT alone. Methods: In this phase 3, open-label trial, subjects with pathologically confirmed SCCHN; N2/N3 disease without metastases; no prior therapy; KPS ³ 70%; and intact organ function were randomized to CRT alone (CRT arm) [5 days of D (25 mg/m2), F (600 mg/m2), hydroxyurea (500 mg BID), and RT (150 cGy BID) followed by a 9 day break] or to 2 cycles of IC [D (75 mg/m2), P (75 mg/m2), F (750 mg/m2 day 1-5)] followed by the same CRT (IC arm). Primary endpoint was OS. Secondary endpoints included DF free survival, failure pattern, and recurrence-free survival (RFS). 280 subjects provided 80% power to detect a hazard ratio HR=0.5 for OS (a=0.05). Results: 280 subjects were accrued from 2004-09 with minimum follow-up 24 months. Of 142 patients randomized to IC, 91% received 2 cycles and 87% continued to CRT. Treatment adherence during CRT was high for docetaxel and hydroxyurea, but fewer than 75% of the patients received target dose of 5FU in both arms. RT was delivered without major deviations in 94% and 95% of patients on IC and CRT arms, respectively. The most common grade 3-4 toxicities during IC were febrile neutropenia (9%) and mucositis (8%), and during CRT (both arms combined) they were mucositis (45%), dermatitis (19%), and leukopenia (17%). Only grade 3-4 leukopenia and neutropenia rates were significantly higher in IC (p=0.002 and p=0.02, respectively). Table shows efficacy. Conclusions: High survival rates were observed in both arms. Further analysis and follow-up may provide insight into why the significant decrease in DF did not translate into improved OS. [Table: see text]

11596 Background: TJMUCH-GI-001 Trial was a randomized, double-blind, placebo-controlled phase III trial to study the efficacy of Monosialotetrahexosylganglioside (GM1) for oxaliplatin-induced peripheral neurotoxicity (OIPN) in GI cancer patients. Majority patients (> 80%) in both arms continued receiving oxaliplatin on the trial. The results showed GM1 effectively reduced OIPN in GI cancer patients. Here we report the survival and safety results of this trial. Methods: Patients were randomized in a 1:1 ratio to receive GM1 or placebo. Patients with OIPN > = G2 by CTCAE 4.03 persisting during or after oxaliplatin-based chemotherapy were eligible. The patients who remained on oxaliplatin after enrollment, received concurrent placebo or GM1 x 7 days with each chemotherapy cycle. The patients who stopped taking oxaliplatin, were treated with placebo or GM1 x 14 days every 3 weeks. GM1 was dosed at 60mg daily for every 3-week or 40mg daily for every 2-week schedule. Trial was continued until modified EORTC QLQ-CIPN20 ( MCIPN) increased by 30% or stayed unchanged after two more treatments beyond completion of oxaliplatin. Survival data for the treatment arms were compared using a log-rank test and Chi-square tests were used for safety analysis. Results: From May 2015 to Dec 2017, 73 patients were enrolled in GM1 and 72 in placebo arm. The median follow-up was 16.6 months (0.8-43.1 months) as of Dec.2018. Four patients lost to follow up. There was no deleterious impact of GM1 on survival. As a matter of fact, receiving GM1 was associated with a trend toward improved PFS and OS (HR=0.74,95%CI, 0.469 - 1.156 for PFS and HR=0.76, 95%CI0.469 - 1.156 for OS). The most frequent Grade 3 or 4 adverse events included neutropenia (8 patients in GM1 group VS. 4 in placebo group) and hypoleukemia (4 patients in GM1 group VS. 1 in placebo group). Other 3 or 4 adverse events (all less than 3 patients) included anorexia, hypercalcemia, nausea, vomiting, proteinuria, hyperbilirubinemia, hypokalemia, hypertension and appendicitis. All the 3 or 4 adverse events were related to chemotherapy, not to GM1. Conclusion: In this placebo-controlled phase III trial, GM1 showed acceptable toxicity with trends favorable PFS and OS in GI cancer patients. Clinical trial information: NCT02486198.
