Purpose Patients with advanced pancreatic adenocarcinoma have a poor prognosis and limited second-line treatment options. Evidence suggests a role for the Janus kinase (JAK)/signal transducer and activator of transcription pathway in the pathogenesis and clinical course of pancreatic cancer. Patients and Methods In this double-blind, phase II study, patients with metastatic pancreatic cancer who had experienced treatment failure with gemcitabine were randomly assigned 1:1 to the JAK1/JAK2 inhibitor ruxolitinib (15 mg twice daily) plus capecitabine (1,000 mg/m2 twice daily) or placebo plus capecitabine. The primary end point was overall survival (OS); secondary end points included progression-free survival, clinical benefit response, objective response rate, and safety. Prespecified subgroup analyses evaluated treatment heterogeneity and efficacy in patients with evidence of inflammation. Results In the intent-to-treat population (ruxolitinib, n = 64; placebo, n = 63), the hazard ratio was 0.79 (95% CI, 0.53 to 1.18; P = .25) for OS and was 0.75 (95% CI, 0.52 to 1.10; P = .14) for progression-free survival. In a prespecified subgroup analysis of patients with inflammation, defined by serum C-reactive protein levels greater than the study population median (ie, 13 mg/L), OS was significantly greater with ruxolitinib than with placebo (hazard ratio, 0.47; 95% CI, 0.26 to 0.85; P = .011). Prolonged survival in this subgroup was supported by post hoc analyses of OS that categorized patients by the modified Glasgow Prognostic Score, a systemic inflammation–based prognostic system. Grade 3 or greater adverse events were observed with similar frequency in the ruxolitinib (74.6%) and placebo (81.7%) groups. Grade 3 or greater anemia was more frequent with ruxolitinib (15.3%; placebo, 1.7%). Conclusion Ruxolitinib plus capecitabine was generally well tolerated and may improve survival in patients with metastatic pancreatic cancer and evidence of systemic inflammation.

e15150 Background: The current standard therapies for metastatic pancreatic adenocarcinoma in Japan are the single-agent Gemcitabine (Gem) or S-1 and Gem plus erlotinib. Irinotecan (CPT-11) is one of the promising drugs for Gem-refractory PC pts. Both Irinotecan and Gem have shown activity against these diseases with different mechanisms and are non-cross-resistant with each other. Japanese pts have the different metabolism with Irinotecan rather than pts in western countries. Methods: The aim of this phase II study was to evaluate the efficacy and safety of CPT-11 and Gem in Japanese pancreatic cancer pts. Patients with MPC and PS 0-2 were enrolled in this phase II trial. CPT-11, 100mg/m (2), was administered in 90 min. and Gem, 1000mg/m (2), was administered in 30 min. soon after CPT-11 on day1. Chemotherapy was repeated biweekly. Results: From May 2002 to May 2006 40 pts, with median age of 62 (40-74) years, were enrolled in this study. The overall response rate (RR) was 15% with disease control rate of 50%. The median progression-free survival (PFS) was 4.0 months (range: 1.0-15.0 months), and median overall survival (OS) was 7.5 months (range: 3.0-24.0 months). Grade 3/4 anemia, leucopenia occurred in 26.3, 5.2% of pts. The most common non-hematologic toxities were fatigue, diarrhea, nausea/vomiting and anorexia. Grade 3 diarrhea and nausea occurred in 10.5% of pts. Conclusions: The combination chemotherapy with Gem and CPT-11 showed favorable RR as expected and the treatment was manageable in Japanese pts with MPC. We plan to evaluate this combination chemotherapy for MPC pts after progression of FOLFIRINOX in near the future. Clinical trial information: UMIN000009963.

213 Background: IPI-926 is a novel, natural product-derived small molecule that targets the Hedgehog (Hh) pathway by inhibiting smoothened. In preclinical models of pancreatic cancer, repressing activation of the Hh pathway diminishes tumor-associated desmoplasia and improves chemotherapy delivery. Methods: This is the final report of the Phase 1b portion of a Phase 1b/2 trial evaluating the safety and efficacy of IPI-926 plus gemcitabine. Eligible patients (pts) with untreated metastatic pancreatic cancer and ECOG status 0-1 were administered oral IPI-926 daily (QD) for 28-day cycles, in 3 to 6 pt dose cohorts. Gemcitabine (1,000 mg/m2) was administered IV weekly for 3 weeks with 1 week off. DLTs were evaluated during Cycle 1. Results: 16 pts (median age 69 years; range 58-86) were enrolled at IPI-926 doses of 110, 130 or 160 mg QD (single agent MTD). Pts received a median of 5 cycles (1-13). Two pts remain on trial. No IPI-926-related serious AEs have been observed. One DLT of Grade 3 AST increase was observed (130 mg dose cohort) and was asymptomatic; it resolved with dose interruption, and did not recur with dose reduction. The most common AEs occurring were fatigue (75% total, 6% ≥ Grade 3), thrombocytopenia (63%, 25%), anemia (56%, 13%), nausea (50%, 0%), diarrhea (44%, 0%), vomiting (44%, 0%), peripheral edema (44%, 0%), pyrexia (44%, 0%), and AST increase (44%, 13%). Dose reductions of IPI-926 occurred in 3 (19%) pts. Dose reductions of gemcitabine occurred in 11 (69%) pts, primarily for thrombocytopenia (9 pts). One pt (6%) discontinued due to an AE (microangiopathic hemolytic anemia). Five (31%) radiographic partial responses were observed (1/3 at 110 mg, 2/6 at 130 mg, 2/7 at 160 mg). Median progression-free survival is > 7 months. 74% of pts were alive 6 months after study entry. Conclusions: IPI-926 plus gemcitabine is well tolerated in pts with untreated metastatic pancreatic cancer, with evidence of activity and no unexpected toxicity. Complete Phase 1b data, including final overall survival, will be presented. Clinical evaluation of this combination continues in the randomized, double-blind, placebo-controlled Phase 2 portion of the trial.

PURPOSE Metastatic pancreatic cancer (mPC) still harbors a dismal prognosis. Our previous trial (PRODIGE 4—ACCORD 11) demonstrated the superiority of 6-month chemotherapy with fluorouracil, leucovorin, irinotecan, and oxaliplatin (FOLFIRINOX) over gemcitabine for overall survival. The high limiting oxaliplatin-related neurotoxicity supports the evaluation of an oxaliplatin stop-and-go strategy and a sequential strategy in mPC. METHODS In this phase II study, patients were randomly assigned to receive either 6 months of FOLFIRINOX (arm A), 4 months of FOLFIRINOX followed by leucovorin plus fluorouracil maintenance treatment for controlled patients (arm B), or a sequential treatment alternating gemcitabine and fluorouracil, leucovorin, and irinotecan every 2 months (arm C). The primary end point was progression-free survival at 6 months. RESULTS Between January 2015 and November 2016, 276 patients (mean age: 63 years; range: 40-76 years) were enrolled (A: 91, B: 92, and C: 90). Grade 3 or 4 neurotoxicity occurred in 10.2% of patients in arm A and 19.8% in arm B. The median ratio of received dose/targeted dose of oxaliplatin was 83% in arm A and 92% in arm B. The 6-month progression-free survival was 47.1% in A, 42.9% in B, and 34.1% in C. The median overall survival was 10.1 months in arm A, 11.2 in arm B, and 7.3 in arm C. Median survival without deterioration in quality-of-life scores was higher in the maintenance arm (11.4 months) than in arms A and C (7.2 and 7.5 months, respectively). CONCLUSION Maintenance with leucovorin plus fluorouracil appears to be feasible and effective in patients with mPC controlled after 4 months of induction chemotherapy with FOLFIRINOX. Severe neurotoxicity was higher in the maintenance therapy arm, probably because of the higher cumulative dose of oxaliplatin.

ObjectivesWe conducted a phase II study to investigate the efficacy and toxicities of irinotecan plus oral S-1 in patients with advanced or recurrent uterine cervical cancer.MethodsPatients with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy were enrolled. Irinotecan (150 mg/m2) was administered intravenously over the course of 90 min on day 1, and S-1 (80 mg/m2) was given orally in two divided doses from days 1 to 14 of a 21 day cycle. The primary endpoint of this phase II study was response rate. Secondary endpoints included safety, progression free survival, and overall survival.ResultsA total of 19 patients were enrolled and treated. The response rate was 29.4%. Grade 3–4 hematologic toxicities were observed in three patients (15.7%). The only grade 3–4 non-hematologic toxicity observed was grade 3 diarrhea. The median progression free survival and overall survival were 3 months and 9 months, respectively.ConclusionS-1 plus irinotecan in a 3 weekly setting is safe and active in women with advanced or recurrent cervical cancer previously treated with platinum based chemotherapy. Future corroborative clinical studies are warranted.

Purpose This nonrandomized multicenter phase II study was performed to evaluate the activity and safety of Ecteinascidin (ET-743) administered at a dose of 1.5 mg/m2 as a 24-hour continuous infusion every 3 weeks in patients with pretreated advanced soft tissue sarcoma. Patients and Methods Patients with documented progressive advanced soft tissue sarcoma received ET-743 as second- or third-line chemotherapy. Antitumor activity was evaluated every 6 weeks until progression, excessive toxicity, or patient refusal. Results One hundred four patients from eight European institutions were included in the study (March 1999 to November 2000). A total of 410 cycles were administered in 99 assessable patients. Toxicity mainly involved reversible grade 3 to 4 asymptomatic elevation of transaminases in 40% of patients, and grade 3 to 4 neutropenia was observed in 52% of patients. There were eight partial responses (PR; objective regression rate, 8%), 45 no change (NC; > 6 months in 26% of patients), and 39 progressive disease. A progression arrest rate (PR + NC) of 56% was observed in leiomyosarcoma and 61% in synovialosarcoma. The median duration of the time to progression was 105 days, and the 6-month progression-free survival was 29%. The median duration of survival was 9.2 months. Conclusion ET-743 seems to be a promising active agent in advanced soft tissue sarcoma, with no cumulative toxicities. The 6-months progression-free survival observed in advanced soft tissue sarcoma compares favorably with those obtained with other active drugs tested in second-line chemotherapy in previous European Organisation for the Research and Treatment of Cancer trials. The median overall survival was unusually long in these heavily pretreated patients mainly due to the high number of patients who benefit from the drug in terms of tumor control.

213 Background: Multiagent chemotherapy with three agents has been shown to delay the emergence of resistance and extend survival in patients with metastatic pancreatic adenocarcinoma. Four drug regimens, even at low doses, may further improve survival by simultaneously targeting multiple non-redundant oncogenic pathways. Methods: A phase II study of GTX-C (capecitabine 500 mg bid on days 1-14, and the combination of gemcitabine 500 mg/m2 (10 mg/m2/min), docetaxel 20 mg/m2 and cisplatin 20 mg/m2 on days 4 and 11) was initiated in newly diagnosed untreated metastatic pancreatic cancer patients. The primary endpoint was progression-free survival rate at 6 months; the regimen would be considered active if the 6-month PFS rate was >75% and inactive if < 50%. Results: Twenty-nine patients were enrolled and 10 patients remain on GTX-C treatment at the time of this report. All patients were ECOG 0 or 1. Eighty-six percent of patients had evidence of liver metastases and 25% had biliary stents in place at time of study enrollment. Median CA19-9 was 6,159 U/mL (37-154,323 U/mL). Median length of follow-up was 9.0 months. Grade 3/4 related adverse events included: nausea/vomiting (7%), transaminitis (10%), anemia (14%), thrombocytopenia (24%), and neutropenia (55%). However, febrile neutropenia occurred in only 3 patients (10%) and not until cycles 6, 14, and 15. PFS rate at 6 months was 76.4% (95% CI: 54.6% - 88.7%). The partial response (PR) rate was 50%, stable disease (SD) rate was 39% and the disease control rate (DCR) was 89%. CA19-9 declines of >80% occurred in 77% of patients with measurable levels. Estimated median PFS was 8.4 months (95% CI: 6.1-10.6 months) and OS was 13.9 months (95% CI: 10.0-17.2 months) at the time of this submission. Updated results will be reported at GI ASCO 2014. Conclusions: GTX-C is highly active and well-tolerated in patients with metastatic pancreatic cancer and should be tested in a larger, comparative study. Clinical trial information: NCT01459614.

663 Background: In mCRC, MET overexpression has been associated with poor prognosis and resistance to anti-VEGF therapy. We initiated a phase II study to evaluate the combination of onartuzumab (O), a ligand-blocking monoclonal antibody directed against the MET receptor, plus bevacizumab and FOLFOX, in first-line mCRC (GO27827; NCT01418222). Methods: This double-blind, randomized, multicenter phase II study randomized patients 1:1 to receive O (10 mg/kg iv) or placebo (P), plus mFOLFOX6 and bevacizumab (5 mg/kg iv). Stratification was by prior adjuvant therapy. All treatments were given on day 1–3 of a 2-week cycle. Oxaliplatin was given for up to 8–12 cycles; all other agents were continued until progression, unacceptable toxicity or death. Primary endpoint was progression-free survival (PFS) in ITT and MET+ subgroup by immunohistochemistry (IHC). MET status was determined by central laboratory IHC evaluation, with scores of 2+ or 3+ considered MET+. Results: From September 2011 to November 2012, 194 patients were enrolled. A recommendation was made to stop O after an interim efficacy and safety analysis in September 2013, due to lack of efficacy. The final analysis (cut-off Feb 2014) found that O did not improve PFS vs. P in the ITT (HR 0.75 [0.52–1.08]; p=0.12) or MET IHC+ populations (n=79; HR 1.03 [0.56–1.89]; p=0.93), although improvement was noted in the MET IHC− population (n=108; HR 0.60 [0.37–0.97]; p=0.03). Neither overall survival (OS) nor response rate (RR) was improved with O vs. P in any of the groups (OS HR 0.96 [0.61–1.50], p=0.85 for ITT; OS HR 1.24 [0.63–2.43], p=0.54 for MET IHC+; OS HR 0.83 [0.44–1.56], p=0.56 for MET IHC−; RR 57.3% vs. 57.7% for ITT, 43.2% vs. 57.1% for MET IHC+, 66.1% vs. 60.8% for MET IHC−). More edema (65.7% vs. 12.9%) and venous thromboembolic events (30.3% vs. 16.1%) were seen with O vs. P, respectively. Grade ≥3 events were similar (86.9% vs. 84.9%) and events leading to discontinuation were increased (48.5% vs. 37.6%) with O vs. P. Conclusions: Adding onartuzumab to FOLFOX/bevacizumab did not prolong PFS in first-line unselected or MET IHC+ mCRC. A trend towards PFS benefit was seen in those with MET IHC− mCRC, contrary to prior reports in other tumor types. Clinical trial information: NCT01418222.

e16081 Background: Sunitinib is a 1st-line standard of care in mRCC. Lack of cross-resistance to sequential VEGF-targeting drugs and the possibility of a successful rechallenge with Sunitinib have been postulated. Whether mRCC patients (pts) could benefit from rechallenge with Sunitinib after progressing on 1st-line Sunitinib and 2nd-line Everolimus was the aim of this phase II study Methods: 39 mRCCpts were prospectively treated with Sunitinib (50 mg/daily, 4:2); main inclusion criteria were: histologically proven RCC with clear cell component, previous 1st-line Sunitinib with a Disease Control Rate lasting at least 10 months, 2nd-line Everolimus, and written informed consent. The primary end-point of this study was 6-months progression-free survival (PFS). A Simon’s 2-stage design was used; after testing Sunitinib on 12 pts in the first stage, the trial would have been terminated if 5 or fewer had a PFS of less than 6 months. Otherwise, the trial would have proceeded to the second stage, enrolling a total of 38 pts. If the total number of pts free of progression at 6 months would have been less than or equal to 18, Sunitinib would have been rejected Results: As a whole, 39 pts (30 males, 9 females) were enrolled. The study quickly moved from the first stage to its completion and ultimately succeeded; indeed, 6-months PFS was 60%, median PFS being 8.6 months (average: 9.59, range: 0.7-24.6 months). In terms of safety no unexpected toxicities were observed. Tx-related grade 3-4 AEs observed in ≥5% of the pts were: hand-foot skin reaction, fatigue, nausea, hypertriglyceridemia, hypophosphatemia, hypocalcemia, hyperglycemia, and neutropenia. One case each of myocardial infarction, atrial flutter and spontaneous pneumothorax were also reported, but resolved Conclusions: Despite an ineluctable time-lead-bias, median PFS on Sunitinib rechallenge was high (8.6 months), clearly showing that many pts may become sensitive again to VEGFRs-inhibition. Although many agents are presently available from 2nd-line on, in countries where treatment options are still limited, Sunitinib rechallenge could still represent a reasonable treatment option. EudraCT number: 2012-000473-23. Clinical trial information: 2012-000473-23.

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.

101 Background: Immune checkpoint inhibitors (ICKi) are highly effective for MSI/dMMR mCRC pts. RECIST1.1 criteria are reported to underestimate response to ICKi. The GERCOR NIPICOL phase II study aimed to evaluate disease control rate (DCR) using RECIST1.1 and iRECIST for MSI/dMMR mCRC pts treated with nivolumab (NIVO) and ipilimumab (IPI). Methods: MSI/dMMR mCRC pts previously treated with fluoropyrimidines (FP), oxaliplatin (OX) and irinotecan (IRI) ± targeted therapies received NIVO 3 mg/kg + IPI 1 mg/kg Q3W for 4 cycles then NIVO 3 mg/kg Q2W until progression or a maximum of 20 cycles. CT-scan tumor assessments were done every 6 weeks during 24 weeks and then every 12 weeks. Primary objective was DCR at 12 weeks (12wDCR) according to RECIST1.1 and iRECIST by central review. Response rates and progression-free survival (PFS) by central review were secondary objectives. A one-stage Fleming design was used with a targeted improvement of 12wDCR from 70% to 85%. Results: Of 57 pts included between Dec 2017 and Nov 2018, 43.9% had received ≥ 3 prior lines including FP (100%), OX (100%), IRI (95.5%), antiangiogenics (57.9%) and anti-EGFRs (45.6%). 17.5% of pts had BRAF mutation and 27.5% Lynch syndrome. Grade 3-4 treatment-related adverse events were reported in 49.1% of pts, mainly hepatitis (12.3%). 12wDCR was 86.0% and 87.7% using RECIST1.1 and iRECIST respectively, with only 1 pseudo-progression (1.8%) observed during the first 12 weeks, and one later. Kappa coefficient between RECIST and iRECIST 12wDCR was 0.92 (95%CI 0.77-1.0). Best observed responses with RECIST1.1/iRECIST were: 2/2 complete responses (3.5/3.5%), 19/19 partial responses (33.3/33.3%), 30/31 stable diseases (52.6/54.4%) and 3/2 disease progressions (5.3/3.5%), with 3 pts not evaluable (cancer-related deaths before first evaluation). Conclusions: Combination of NIVO and IPI in MSI/dMMR mCRC is associated with a low frequency of pseudo-progression and high DCR rate. PFS will be evaluated in Dec 2019, with all pts having completed the predefined 1-year of ICKi therapy. Clinical trial information: NCT033501260.
