Introduction: Liposomal irinotecan (nal-IRI) plus fluorouracil/leucovorin (5-FU/LV) has shown clinical benefit in patients with metastatic pancreatic adenocarcinoma (mPAC) who progressed on gemcitabine-based chemotherapy. However, its role in patients with mPAC previously treated with conventional irinotecan-containing chemotherapy has not been appropriately investigated. Methods: In this retrospective analysis, patients with mPAC who received nal-IRI plus 5-FU/LV after conventional irinotecan-containing regimen between January 2017 and March 2020, were identified from two referral cancer centers in South Korea. The ratio of time to progression (TTP) with nal-IRI plus 5-FU/LV to TTP with conventional irinotecan (TTPr) was analyzed with respect to the duration and cumulative dose of conventional irinotecan treatment. Results: In total, 35 patients treated with nal-IRI plus 5-FU/LV after the irinotecan-containing regimen were analyzed. The median age was 58 years and 16 (46%) patients were male. The median duration of conventional irinotecan therapy was 4.6 months at a median cumulative dose of 1230 mg. The objective response rate of nal-IRI plus 5-FU/LV was 2.9%, and stable disease was achieved in 11 (31.4%) patients. During the median follow-up of 9.2 [95% confidence interval (CI): 7.8–10.5] months, the median progression-free survival (PFS) and overall survival (OS) were 2.0 (95% CI: 1.4–2.6) months and 4.4 (95% CI: 3.6–5.7) months, respectively. The 6-month PFS and OS rates were 16.3% and 37.5%, respectively. The median TTPr was 0.41 (range, 0.07–2.07), showing a negative correlation with the cumulative dose of prior irinotecan therapy (R = −0.37, p = 0.041). A tentative negative correlation between TTPr and duration of prior irinotecan therapy was observed ( R = −0.35, p = 0.062). The most common grade 3–4 toxicities were neutropenia (20%) and fatigue (8.6%). Conclusion: Nal-IRI plus 5-FU/LV showed modest effectiveness and manageable toxicities for patients with mPAC previously treated with conventional irinotecan-containing chemotherapy. The cumulative dose of prior conventional irinotecan therapy may be inversely correlated with the effectiveness of nal-IRI plus 5-FU/LV.

382 Background: Liposomal irinotecan (nal-IRI) plus fluorouracil/leucovorin (5-FU/LV) has demonstrated its clinical benefit in patients with metastatic pancreatic adenocarcinoma (mPAC) who progressed on prior gemcitabine-based chemotherapy. However, its role in patients who previously treated with conventional irinotecan has not been investigated. We analyzed clinical outcomes of nal-IRI + 5-FU/LV in mPAC patients after progression on conventional irinotecan-containing chemotherapy. Methods: In this multicenter retrospective analysis, a total of 35 patients with mPAC who received nal-IRI + 5-FU/LV after progression on irinotecan-containing regimen, between January 2017 and March 2020, were included. The ratio of time-to-progression (TTP) with nal-IRI + 5-FU/LV to TTP with conventional irinotecan (TTPr) was correlated with duration and cumulative dose of prior conventional irinotecan. Results: The median age was 58 years (range, 35-73) and 16 patients (46%) were male. All patients received prior irinotecan as the component of FOLFIRINOX. The median duration of prior irinotecan was 4.6 months (range, 0.5-16.8) and median cumulative dose of prior irinotecan was 1230 mg (range, 150-4650). Objective response rate of nal-IRI + 5-FU/LV was 2.9% (1 partial response) and stable disease was achieved in 31.4% (n = 11). With median follow-up duration of 9.2 months [95% CI, 7.8-10.5], the median PFS and OS were 2.0 months [95% CI, 1.4-2.6] and 4.4 months [95% CI, 3.6-5.7], respectively. 6-month PFS rate was 16.3% and OS rate was 37.5%. The median TTPr was 0.41 (range 0.07-2.07) and this showed negative correlation between cumulative dose of prior irinotecan (R = -0.37, p = 0.041). There was a tendency for the negative correlation between TTPr and duration of prior irinotecan (R = -0.35, p = 0.062). Most common grade 3-4 toxicities were neutropenia (20%) and fatigue (8.6%). Conclusions: Nal-IRI + 5-FU/LV showed only modest efficacy for mPAC patients who progressed on conventional irinotecan-containing chemotherapy. Cumulative dose of prior conventional irinotecan may be correlated with the efficacy of nal-IRI + 5-FU/LV.

Liposomal Irinotecan

Background: Liposomal irinotecan (nal-IRI) plus 5-fluorouracil and leucovorin (5-FU/LV) was effective and well-tolerated in patients with metastatic pancreatic adenocarcinoma (mPAC) that progressed on gemcitabine-based therapy in the global NAPOLI-1 trial. Real-world data may further clarify the outcomes and safety profile of nal-IRI + 5-FU/LV in clinical practice. Methods: This retrospective analysis included patients with mPAC who received nal-IRI + 5-FU/LV following gemcitabine-based therapy under a Managed Access Program in Korea. Results: From January 2017 to April 2018, 86 patients across 10 institutions received nal-IRI + 5-FU/LV (median age, 61 years; 60% male; ECOG performance status, 0–1). A total of 35 (41%) and 51 (59%) patients had received less than two and two or more lines of chemotherapy before inclusion, respectively. At a median follow up of 6.4 months, median overall survival (OS) was 9.4 months (95% confidence interval [CI] 7.4–11.4) and median progression-free survival (PFS) was 3.5 months (95% CI 1.3–5.7). Six-month OS and PFS rates were 65.1% and 37.5%, respectively. Objective response and disease control rates were 10% and 55%, respectively. Most common grade 3–4 toxicities were neutropenia (37.2%), nausea (10.5%), vomiting (9.3%), anorexia (8.1%) and diarrhoea (4.7%). Conclusion: Real-life data for Korean patients indicate that, consistent with NAPOLI-1, nal-IRI + 5-FU/LV is effective and well-tolerated in patients with mPAC that progressed on gemcitabine-based therapy.

<b>Purpose:</b> Patients with advanced endometrial carcinoma have limited treatment options. We report final primary efficacy analysis results for a patient cohort with advanced endometrial carcinoma receiving lenvatinib plus pembrolizumab in an ongoing phase Ib/II study of selected solid tumors. <b>Methods:</b> Patients took lenvatinib 20 mg once daily orally plus pembrolizumab 200 mg intravenously once every 3 weeks, in 3-week cycles. The primary end point was objective response rate (ORR) at 24 weeks (ORRWk24); secondary efficacy end points included duration of response (DOR), progression-free survival (PFS), and overall survival (OS). Tumor assessments were evaluated by investigators per immune-related RECIST. <b>Results:</b> At data cutoff, 108 patients with previously treated endometrial carcinoma were enrolled, with a median follow-up of 18.7 months. The ORRWk24 was 38.0% (95% CI, 28.8% to 47.8%). Among subgroups, the ORRWk24 (95% CI) was 63.6% (30.8% to 89.1%) in patients with microsatellite instability (MSI)-high tumors (n = 11) and 36.2% (26.5% to 46.7%) in patients with microsatellite-stable tumors (n = 94). For previously treated patients, regardless of tumor MSI status, the median DOR was 21.2 months (95% CI, 7.6 months to not estimable), median PFS was 7.4 months (95% CI, 5.3 to 8.7 months), and median OS was 16.7 months (15.0 months to not estimable). Grade 3 or 4 treatment-related adverse events occurred in 83/124 (66.9%) patients. <b>Conclusion:</b> Lenvatinib plus pembrolizumab showed promising antitumor activity in patients with advanced endometrial carcinoma who have experienced disease progression after prior systemic therapy, regardless of tumor MSI status. The combination therapy had a manageable toxicity profile. <b>Trial registration:</b> ClinicalTrials.gov NCT02501096.

Objective: To study the efficacy and toxicity of irinotecan combined with oxaliplatin and S-1 in patients with metastatic pancreatic adenocarcinoma. Patients and methods: Previously untreated patients with cytologically or histologically confirmed metastatic pancreatic adenocarcinoma underwent a treatment regimen consisting of an intravenous infusion of irinotecan 165 mg/m2 and oxaliplatin 85 mg/m2 on day 1, and oral S-1 40 mg/m2 twice daily on days 1–14, repeating the regimen every 21 days until one of the following occurred: disease progression, intolerable toxicity, or patient death. The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS), response rate, toxicity, and quality of life. This ongoing study had been registered on ClinicalTrials.gov, NCT03726021. Results: A total of 41 patients were enrolled in this study, 18 men and 23 women. The median PFS was 4.33 months [95% confidence interval (CI): 2.83–5.88] and the median OS was 11.00 months (95% CI: 9.16–12.84). There were no instances of a complete response; the partial response, stable disease, and disease progression rates were 39.02% (16/41), 29.27% (12/41), and 31.71% (13/41), respectively. The most common adverse side effects were mild to moderate nausea, vomiting, neutropenia, and thrombocytopenia. Grade 3 or 4 neutropenia and thrombocytopenia were observed in 29.27% (12/41) and 12.20% (5/41) of the patients, respectively. No treatment-related death was observed. Conclusion: Irinotecan combined with oxaliplatin and S-1 is a safe and effective treatment for metastatic pancreatic adenocarcinoma, and any toxicities are mild to moderate and tolerable. A larger study population is needed for further evaluation.

8009 Background: Vandetanib is a once-daily oral inhibitor of VEGFR, EGFR and RET signaling. This phase III study compared the efficacy of vandetanib vs erlotinib in patients (pts) with advanced, previously treated NSCLC. Methods: Eligible pts (stage IIIB/IV NSCLC, PS 0–2, 1–2 prior chemotherapies; all histologies permitted) were randomized 1:1 to receive vandetanib 300 mg/day or erlotinib 150 mg/day until progression/toxicity. The primary objective was to show superiority in progression-free survival (PFS) for vandetanib vs erlotinib. Secondary endpoints included overall survival (OS), objective response rate (ORR), time to deterioration of symptoms (TDS; EORTC QoL Questionnaire) and safety. Results: Between Oct 06-Nov 07, 1240 pts (mean age 61 yrs; 38% female; 22% squamous) were randomized to receive vandetanib (n=623) or erlotinib (n=617). Baseline characteristics were similar in both arms. Median duration of follow-up was 14 months, with 88% pts progressed and 67% dead. There was no difference in PFS for pts treated with vandetanib vs erlotinib (hazard ratio [HR] 0.98, 95.22% CI 0.87–1.10; P=0.721), and no difference in the secondary endpoints of OS (HR 1.01, 95.08% CI 0.89–1.16; P=0.830), ORR (both 12%) and TDS (pain: HR 0.92, P=0.289; dyspnea: HR 1.07, P=0.407; cough: HR 0.94, P=0.455). A preplanned non-inferiority analysis for PFS and OS demonstrated equivalent efficacy for vandetanib and erlotinib. The adverse events (AEs) observed for vandetanib were generally consistent with previous NSCLC studies with vandetanib 300 mg. There was a higher incidence of some AEs (any grade) with vandetanib vs erlotinib, including diarrhea (50% vs 38%) and hypertension (16% vs 2%); rash was more frequent with erlotinib (38% vs 28%). The overall incidence of CTCAE grade ≥3 AEs was also higher with vandetanib (50% vs 40%). The incidence of protocol-defined QTc prolongation in the vandetanib arm was 5%. Conclusions: The study did not meet its primary objective of demonstrating PFS prolongation with vandetanib vs erlotinib in pts with previously treated advanced NSCLC. However, vandetanib and erlotinib showed equivalent efficacy for PFS and OS in a preplanned non-inferiority analysis. [Table: see text]

1009 Background: The oral Akt inhibitor IPAT is being evaluated in cancers with a high prevalence of PI3K/Akt pathway activation, including TNBC. Methods: Eligible patients (pts) had measurable inoperable locally advanced/metastatic TNBC previously untreated with systemic therapy. Pts were stratified by prior (neo)adjuvant therapy, chemotherapy-free interval and tumor PTEN status, and randomized 1:1 to P 80 mg/m2 (d1, 8 & 15) with either IPAT 400 mg or PBO (d1–21) q28d until progression or unacceptable toxicity. Co-primary endpoints were progression-free survival (PFS) in the ITT population and pts with PTEN-low tumors by IHC. Secondary endpoints included objective response rate (ORR), duration of response (DoR) and overall survival in the ITT and IHC PTEN-low populations, efficacy in pts with PIK3CA/AKT1/PTEN-altered tumors by next-generation sequencing (NGS), and safety. Results: Baseline characteristics were generally balanced between arms. Efficacy is shown below. The most common grade ≥3 AEs (grouped terms) were diarrhea (23% IPAT+P vs 0% PBO+P; no grade 4 or colitis in either arm), neutropenia (18% vs 8%), asthenia (5% vs 6%), peripheral neuropathy (5% vs 5%) and pneumonia (5% vs 0%). More pts receiving IPAT+P than PBO+P had an AE leading to dose reduction of IPAT/PBO (21% vs 6%) or P (38% vs 11%) but median cumulative dose intensity was similar (IPAT/PBO: 99% vs 100%; P: 100% vs 100%). AEs led to IPAT/PBO discontinuation in 13% vs 11% of pts, respectively; 2 pts (3%) discontinued IPAT for grade 3 diarrhea. Conclusions: Adding IPAT to P for TNBC modestly improved PFS in the ITT pts. The effect was more pronounced in the prespecified subgroup with PIK3CA/AKT1/PTEN alterations, warranting further evaluation of IPAT in these pts. AEs were manageable. Clinical trial information: NCT02162719. [Table: see text]

191 Background: Avelumab is a human anti–PD-L1 IgG1 monoclonal antibody that is approved for the treatment of metastatic Merkel cell carcinoma (US and EU) and advanced urothelial carcinoma progressed on platinum therapy (US). Here, we report phase 1b data for avelumab in a cohort of patients (pts) with previously treated metastatic melanoma. Methods: Pts with unresectable stage IIIC or IV melanoma progressed after ≥1 line of therapy for metastatic disease received avelumab 10 mg/kg IV Q2W until progression, unacceptable toxicity, or withdrawal. Endpoints included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), and adverse events (AEs; NCI CTCAE v4.0). Results: As of Dec 31, 2016, 51 pts were treated and followed for a median of 24.2 mo (range 16.1–31.5). Median age was 64 y (range 31–84). Site of primary tumor was cutaneous (n = 28, 54.9%), ocular (n = 16, 31.4%), mucosal (n = 2, 3.9%), or unknown (n = 5, 9.8%). Pts had received a median of 2 prior lines of therapy for advanced disease (range 0–4), including ipilimumab (n = 26, 51.0%). Confirmed ORR was 21.6% (95% CI 11.3–35.3), with complete response in 7.8% and partial response in 13.7%. In pts with cutaneous melanoma, ORR was 28.6% (95% CI 13.2–48.7). There were no objective responses in pts with ocular melanoma; however, 7 pts (43.8%) had stable disease. In pts with ≤1 (n = 25), 2 (n = 17), or ≥3 (n = 9) prior lines, ORR was 36.0% (95% CI 18.0–57.5), 11.8% (95% CI 1.5–36.4), and 0% (95% CI 0–33.6), respectively. Antitumor activity by PD-L1 status will be presented. Median duration of response was not estimable (NE) (95% CI 2.6 mo–NE). Median PFS was 3.1 mo (95% CI 1.4–6.3) and the 6-mo PFS rate was 39.2% (95% CI 25.2–52.9). Median OS was 18.5 mo (95% CI 9.3–NE) and the 12-mo OS rate was 62.3% (95% CI 46.9–74.4). 39 pts (76.5%) had a treatment-related (TR)AE, most commonly infusion-related reaction (25.5%), fatigue (17.6%), and chills (11.8%). 4 pts (7.8%) had a grade ≥3 TRAE. 5 pts (9.8%) had an immune-related AE; all were grade 1/2. No treatment-related deaths occurred. Conclusions: Avelumab showed durable responses, promising survival outcomes, and an acceptable safety profile in pts with previously treated metastatic melanoma. Clinical trial information: NCT01772004.

467 Background: Both FOLFIRINOX and Nab-paclitaxel plus Gemcitabine standard treatment in first-line treatment of metastatic pancreatic adenocarcinoma (MPA). It could be of interest to use them consecutively, knowing that there is currently no standard for 2nd line treatments for MPA. The aim of this study was to evaluate the efficacy and tolerability of modified FOLFIRINOX after gemcitabine plus Nab-paclitaxel failure in MPA. Methods: From January 2015 to March 2016, medical records were retrospectively reviewed for consecutive patients receiving modified FOLFIRINOX for a histologically proven MPA after failure of Nab-paclitaxel plus Gemcitabine. Patients were treated with modified FOLFIRINOX every 2 weeks as follows: intravenous oxaliplatin 85 mg/m2, irinotecan 150 mg/m2, 5-FU infusion 2,400 mg/m2 over 46 h, no bolus 5-FU, until disease progression, patient refusal or unacceptable toxicity. Results: Modified FOLFIRINOX was administered to 23 pts. Among these patients, median age was 64 years (range 42.4 - 74.2). 83% of the patients had a PS 0, the primary site of the tumor was the head of the pancreas in 39% of patients, and 26% of patients experienced recurrence after resection. Disease control rate was 66.7% (n = 17) with a 23.8 % (n = 17) objective response rate (RECIST). Within the whole cohort, median PFS was 4.3 months (95% CI: 3.1-5.3) and median overall survival (OS) was 9.3 months (95% CI: 3.8-14.8). Since the start date of first line chemotherapy with Nab-paclitaxel plus Gemcitabine, median OS was 18.8 months (95% CI: 9.6-27.9). No toxic death occured. Grade 3-4 toxicities were reported in 30% of patients and were neutropenia (17%), anemia (8%), cholangitis (8%) and acute kidney injury (4%). Conclusions: Modified FOLFIRINOX seems promising with a manageable toxicity profile after Nab-paclitaxel plus Gemcitabine failure, in selected patients able to receive second line treatment for a MPA. These promising results have now to be confirmed in a phase III randomized trial.

512 Background: NIVO monotherapy is approved in the United States and other countries for pts with HCC treated with sorafenib (SOR) based on CheckMate 040 (NCT01658878) results, which reported 14% objective response rate (ORR) and 16-month median overall survival (mOS; El-Khoueiry et al. Lancet 2017). Primary efficacy and safety of NIVO + IPI in pts with aHCC previously treated with SOR were presented recently (Yau et al. J Clin Oncol 2019). Here, we will present subgroup analyses from this study. Methods: Pts were randomized to 3 arms: [A] NIVO 1 mg/kg + IPI 3 mg/kg Q3W (4 doses) or [B] NIVO 3 mg/kg + IPI 1 mg/kg Q3W (4 doses), each followed by NIVO 240 mg Q2W, or [C] NIVO 3 mg/kg Q2W + IPI 1 mg/kg Q6W. Treatment continued until intolerable toxicity or disease progression. Primary endpoints included safety/tolerability, ORR, and duration of response (DOR; investigator assessment per RECIST v1.1). Key secondary endpoints included disease control rate (DCR), OS, and progression-free survival (blinded independent central review [BICR] per RECIST v1.1); key exploratory endpoints included ORR (BICR per RECIST v1.1). Data cutoff was January 2019. Results: A total of 148 pts were randomized. Minimum OS follow-up from last pt randomization date to data cutoff was 28 months. At baseline, 34% of all pts had vascular invasion; 82% had extrahepatic spread; and 91% had Barcelona Clinic Liver Cancer stage C; 84% discontinued SOR because of disease progression and 14% because of toxicity. For all treated pts, ORR was 31% (7 had complete response), with median DOR of 17 months; DCR was 49%; the 30-month OS rate was 37%. NIVO + IPI was well tolerated; 38% of pts had grade 3–4 treatment-related adverse events (TRAEs; most common any grade: pruritus and rash; most common grade 3–4: aspartate aminotransferase increase and lipase increase); 5% had grade 3–4 TRAEs leading to discontinuation. Subgroup analyses based on duration of prior SOR therapy and other pt characteristics will be presented. Conclusions: NIVO + IPI led to clinically meaningful benefits, with a manageable safety profile in pts previously treated with SOR. NIVO + IPI may provide a new treatment option for these pts. Clinical trial information: NCT01658878.

Metastatic Pancreatic Adenocarcinoma

TPS4149 Background: Lysyl oxidase-like molecule 2 (LOXL2) is an extracellular matrix enzyme that catalyzes the covalent cross-linking of collagen and is widely expressed across desmoplastic tumors. Simtuzumab (GS-6624) is a humanized antibody that specifically inhibits LOXL2 enzymatic activity. Inhibiting LOXL2 is expected to block formation of desmoplasia, which is thought to play an important role in tumor progression and metastasis. Methods: The primary objective and of the study is to compare the additive efficacy of simtuzumab vs. placebo in combination with gemcitabine as measured by improvement in progression free survival (PFS). The secondary objective is to compare the additive efficacy of simtuzumab vs. placebo as measured by overall survival (OS) and objective response rate. Study Design: The study is a randomized, double-blind, placebo controlled Phase 2 trial in subjects with metastatic pancreatic adenocarcinoma. A total of 234 subjects will be randomized to 200 mg simtuzumab, 700 mg simtuzumab, or placebo at a 1:1:1 ratio (78 subjects per treatment group) in combination with gemcitabine in cycles of 28 days. In each cycle, subjects will receive IV GS-6624 or placebo infused on Days 1 and 15, and IV gemcitabine (1000 mg/m2) on Days 1, 8, and 15. CT or MRI scans will be performed every 8 weeks to evaluate response to treatment. Subjects will continue courses of treatment every 28 days in the absence of disease progression or unacceptable toxicity. As of January 30, 2013, 162 subjects have been randomized. Clinical trial information: NCT01472198.
