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 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.

Purpose To determine whether addition of the farnesyltransferase inhibitor tipifarnib (Zarnestra, R115777; Johnson and Johnson Pharmaceutical Research and Development, Beerse, Belgium) to standard gemcitabine therapy improves overall survival in advanced pancreatic cancer. Patients and Methods This randomized, double-blind, placebo-controlled study compared gemcitabine + tipifarnib versus gemcitabine + placebo in patients with advanced pancreatic adenocarcinoma previously untreated with systemic therapy. Tipifarnib was given at 200 mg bid orally continuously; gemcitabine was given at 1,000 mg/m2 intravenously weekly × 7 for 8 weeks, then weekly × 3 every 4 weeks. The primary end point was overall survival; secondary end points included 6-month and 1-year survival rates, progression-free survival, response rate, safety, and quality of life. Results Six hundred eighty-eight patients were enrolled. Baseline characteristics were well balanced between the two treatment arms. No statistically significant differences in survival parameters were observed. The median overall survival for the experimental arm was 193 v 182 days for the control arm (P = .75); 6-month and 1-year survival rates were 53% and 27% v 49% and 24% for the control arm, respectively; median progression-free survival was 112 v 109 days for the control arm. Ten drug-related deaths were reported for the experimental arm and seven for the control arm. Neutropenia and thrombocytopenia grade ≥ 3 were observed in 40% and 15% in the experimental arm versus 30% and 12% in the control arm. Incidences of nonhematologic adverse events were similar in two groups. Conclusion The combination of gemcitabine and tipifarnib has an acceptable toxicity profile but does not prolong overall survival in advanced pancreatic cancer compared with single-agent gemcitabine.

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.

396 Background: RX-3117 is an oral small-molecule antimetabolite, cyclopentyl pyrimidyl nucleoside that is activated by uridine cytidine kinase 2. RX-3117 has shown efficacy in xenograft models of gemcitabine resistant pancreatic, bladder and colorectal cancer. Data from stage 2 of the Phase 1b/2a clinical study of RX3117 as a single agent in subjects with metastatic pancreatic cancer is described below. Methods: Stage 2 of the Phase 1b/2a study (NCT02030067) is designed to evaluate safety, tolerability and efficacy following treatment with 700 mg administered orally once-daily for 5 consecutive days with 2 days off per week for 3 weeks with 1 week off in each 4 week cycle. Eligible subjects (aged ≥ 18 years) had relapsed/refractory metastatic pancreatic cancer. The primary endpoint is a ≥ 20% rate of progression free survival (PFS) benefit (i.e., proportion of subjects with stable disease for at least 4 months) and/or a 10% of evaluable subjects with a partial response rate or better. Results: As of Sep 2017, 44 subjects have been enrolled (22 females, 22 males). The median age was 68 years, ECOG performance statuses were 0 (13 subjects) and 1 (31 subjects) and 6 subjects had received 4 or more prior therapies. One subject had an unconfirmed partial response and 21 subjects met the primary endpoint of stable disease with a duration of 30-224 days. The most frequent adverse events were mild to moderate anemia (19%), mild to moderate fatigue (15%), mild to moderate diarrhea (11%), and severe anemia (9%). Conclusions: This ongoing trial shows an early efficacy signal where RX-3117 is active against advanced pancreatic cancer. The study continues to enroll subjects with advanced pancreatic cancer into stage 2. A phase 2 study with nab-paclitaxel in first-line patients with advanced pancreatic cancer has been started. Clinical trial information: NCT02030067.

Abstract Neutropenia is a common side effect associated with nab-paclitaxel gemcitabine (Nab-Gem) therapy. We retrospectively investigated the association between neutropenia induced by first-line Nab-Gem and survival in metastatic pancreatic carcinoma patients. Metastatic pancreatic patients treated with first-line Nab-Gem were included in this retrospective analysis. Neutropenia was categorized using the National Cancer Institute Common Toxicity Criteria scale. Outcome measures were overall survival (OS), progression-free survival (PFS) and response rate. 115 patients were analyzed. Median PFS was 7 months (95% CI 5–8) for patients with grade ≥ 3 neutropenia and 6 months (95% CI 5–6) for patients with grade < 3 neutropenia [p = 0.08; hazard ratio (HR 0.68)]. Median OS was 13 months (95% CI 10–18) for patients with grade ≥ 3 neutropenia and 10 months (95% CI 8–13) for patients with grade < 3 neutropenia (p = 0.04; HR 0.44). In multivariate analysis, the occurrence of grade ≥ 3 neutropenia showed a statistically significant association with OS (HR 0.62; 95% CI 0.09–0.86; p = 0.05). Nab-Gem-induced neutropenia is associated with longer survival in metastatic pancreatic cancer patients.

e14614 Background: Conroy et al reported a significant improvement in overall survival of patients with metastatic pancreatic cancer treated with FOLFIRINOX compared to single agent gemcitabine. The regimen was associated with significant grade 3/ 4 toxicities, such as myelosuppression(46%), fatigue(24%), vomiting(15%) and diarrhea (13%). In order to improve the toxicity profile, we have modified FOLFIRINOX (mFOLFIRINOX) regimen by removing the bolus 5-FU and adding the routine use of growth factor prophylaxis. We present our experience with mFOLFIRINOX in patients with locally advanced or metastatic pancreatic cancer. Methods: After obtaining IRB approval, patients with a diagnosis of pancreatic cancer were identified from the Emory University tumor registry. Twenty eight patients who received at least one dose of mFOLFIRINOX (5-FU 2400 mg/m2 CIVI over 46 hours, leucovorin 400 mg/m2, oxaliplatin 85 mg/m2, irinotecan 180 mg/m2 and pegfilgrastim 6 mg every two weeks ) were selected and their charts were retrospectively reviewed for safety, response, and survival. Results: Of 28 patients, 14 (50%) were male, 18 (64%) white, 8 (29%) black and other 2(7%). Median age was 63 (50-75) and ECOG performance status 0-1. Nineteen (68%) patients had primary tumor located in head of pancreas. Eight patients (29%) experienced grade 3/4 toxicities, i.e., nausea/vomiting (11%), diarrhea (11%), fatigue (11%), neuropathy (4%), neutropenia (4%), thrombocytopenia(4%), and sepsis not-related to neutropenia (4%). No grade 3/4 anemia or febrile neutropenia was noted. mFOLFIRINOX controlled the disease in 20 patients (71%) with 2 CR, 4 PR and 14 SD. With a median follow up of 5.5 months, median overall or progression free survival is not reached. Two patients have died and six patients have progressed. Conclusions: Modified FOLFIRINOX is well tolerated in this US population. The clinical activity appears very promising with majority of patients being free of progression.

Abstract Purpose: To compare the efficacy and toxicity of three different chemotherapy regimens used as first-line treatments in the real-life management of metastatic pancreatic cancer (mPC). Methods: A total of 218 patients diagnosed with mPC at the time of initial admission were included in this multicenter study. Gemcitabine (Gem, n=71), Gemcitabine-cisplatin (Gem-Cis, n=91) and FOLFIRINOX (FFX, n=56) treatments were compared in terms of efficacy and treatment-related toxicity. Results: Overall response rate was significantly higher in the FFX group (50.0%) than in the Gem (28.2%) and Gem-Cis (27.5%) groups (p=0.010).Median progression-free survival (8.4 vs. 4.6 and 5.5 months, respectively, p<0.001) and overall survival (16.4 vs. 8.1 and 8.7 months, respectively, p=0.002) were significantly longer in theFFX group than in the Gem and Gem-Cis groups. Toxicity of any grade was noted in 46(64.8%), 56(61.5%) and 49(87.5%) patients in the Gem, Gem-Cis and FFX groups, respectively (p=0.003).Of the grade 3-4 toxicities, weakness/fatigue and mucositis were reported only in the FFX group (5.4% and 3.6%, respectively). Grade 3-4 diarrhea (10.7%, 0.0%, 2.2%, respectively) and neutropenia (25%, 4.2% and 5.5%, respectively) were more common in the FFX group than in the Gem and Gem-Cis groups. Conclusion: In conclusion, our findings indicate that FFX regimen provides a significant advantage over the other treatment regimens in terms of response rates and survival. Treatment toxicity was more frequent but manageable with the FFX regimen.FFX seems to be a preferable regimen in the first-line treatment of the younger and fit patients diagnosed with mPC.

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.

412 Background: VHL is inactivated in most clear cell RCC (ccRCC) tumors giving rise to the HIF hypoxia response program and tumor angiogenesis. Antiangiogenic therapies are active in ccRCC, but resistance develops in all pts. Dual inhibition strategies may be needed to overcome resistance. CRLX101, a novel nano pharmaceutical formulation of camptothecin, has been shown in pre-clinical models to target HIF. We combined CRLX101 with bev in the treatment of pts with refractory mRCC in order to determine the safety and the recommended phase 2 dose (RP2D) of the combination, and to determine the therapeutic activity of treatment. Methods: Pts with mRCC refractory to conventional antiangiogenic therapies (all subtypes) were treated every 2 weeks with bev 10 mg/kg and escalating doses of CRLX101 (12 mg/m2, 15 mg/m2) in a standard 3+3 design with an expansion at the RP2D. Pts were treated until progression, death, or prohibitive toxicity. Adverse events were classified using CTCAE v 4.0. Radiographic results were assessed by RECIST v1.1. Results: 10 pts were enrolled on study – 6 clear cell, 2 papillary, 2 chromophobe. Median prior number of therapies was 2. No dose limiting toxicities were observed. CRLX101 at its single-agent RP2D (15 mg/m2) was safely combined with standard bev. 2 episodes of grade 3 non-infectious cystitis and 1 episode of grade 3 hypertension were observed. All other toxicities were grade 1 or 2. The median progression free survival (PFS) was 7.6 months which exceeded our pre-specified threshold of 16 weeks and has triggered 2nd stage accrual. 3 of 9 evaluable pts (33%) achieved a confirmed partial response (PR) including 1 patient with papillary mRCC; 4 pts (44%) displayed stable disease, and 2 had progressive disease as their best overall response. Conclusions: Our results demonstrate that CRLX101 can be safely combined with bev in pts with refractory mRCC. The RP2D is 15 mg/m2 q2w of CRLX101 with standard bev. Preliminary outcomes to date suggest that clinical benefit, manifest as prolonged PFS, is conferred to pts with all histologic subtypes of mRCC. Clinical trial information: NCT01625936.

<b><i>Introduction:</i></b> Patients with advanced pancreatic cancer have a poor prognosis. FOLFIRINOX (FFX) and gemcitabine plus nab-paclitaxel (GnP) have been established as first-line treatment, but they have not been confirmed as second-line treatment after FFX. The aim of this study was to evaluate the safety and efficacy of GnP as second-line therapy after FFX in patients with unresectable pancreatic cancer. <b><i>Methods:</i></b> Twenty-five patients with unresectable pancreatic cancer were enrolled. The patients were treated with GnP after FFX between September 2015 and September 2019. Tumor response, progression-free survival (PFS), overall survival (OS), and incidence of adverse events were evaluated. <b><i>Results:</i></b> The response rate, disease control rate, median PFS, and median OS were 12%, 96%, 5.3 months, and 15.6 months, respectively. The common grade 3 or 4 adverse events were neutropenia (76%) and anemia (16%). <b><i>Conclusions:</i></b> GnP after FOLFIRINOX is expected to be one of the second-line recommendations for patients with unresectable pancreatic cancer.
