AbstractLiposomal irinotecan plus 5-fluorouracil/leucovorin (nal-IRI + 5-FU/LV) has shown to provide survival benefits for patients with gemcitabine-refractory metastatic pancreatic ductal adenocarcinoma (PDAC) in NAPOLI-1 trial, in which Asian patients experienced more hematological toxicity and subsequent dose modification. A retrospective chart review to investigate the administration pattern, therapeutic efficacy and safety profile of nal-IRI + 5-FU/LV in 44 consecutive patients with gemcitabine-refractory advanced PDAC treated between December 2016 and December 2018 in National Cheng Kung University Hospital, Taiwan. Most of them had metastatic diseases (88.6%), one-line of prior treatment (72.7%), ECOG PS 0-1 (72.7%) and starting dose of nal-IRI at 60 mg/m2 (≈52 mg/m2 irinotecan free-base) in 65.9%. The overall response rate was 9.1%. The median OS was 6.6 months for the entire cohort, and 7.8 and 2.7 months for patients of ECOG PS 0-1 and>2, respectively. The median OS of ECOG PS 0-1 patients with nal-IRI starting doses at 80 mg/m2 (≈70 mg/m2 irinotecan free-base, n = 13) and 60 mg/m2 (n = 19) were 7.5 and 8.4 months, respectively. Thirty-four percent of patients experienced manageable grade 3-4 hematological toxicity. Our results confirm the clinical benefit of nal-IRI + 5-FU/LV for patients of gemcitabine-refractory advanced PDAC with good performance status in a real-world setting.

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

BackgroundThe NAPOLI-1 trial demonstrated that liposomal irinotecan in combination with fluorouracil (5-FU) and leucovorin (LV) prolonged survival with a manageable safety profile in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) previously treated with gemcitabine-based therapy. Real-world data on clinical outcomes associated with liposomal irinotecan in NAPOLI-1-based regimens is needed to further substantiate this.MethodsThis real-world, retrospective chart review study included patients with mPDAC who received NAPOLI-1-based regimens from six academic centers in the United States. Liposomal irinotecan initiation defined the index date. Overall survival (OS) and progression-free survival (PFS) were assessed with Kaplan-Meier methodology.ResultsThere were 374 patients evaluated; median age was 68 years, and 51% were female. Among 326 patients with baseline ECOG information, approximately 74% had ECOG score <2. Liposomal irinotecan was administered as a doublet with 5-FU in a NAPOLI-1-based regimen in the first line (1L; 16%), 2L (42%), and 3L+ (42%) of the metastatic setting. For patients treated in 1L, 2L, and 3L+, median [95% confidence interval (CI)] OS was 8.0 [5.1, 11.2], 7.3 [5.3, 8.8], and 4.6 [4.0, 5.7] months, and median [95% CI] PFS was 4.2 [2.2, 6.6], 3.0 [2.6, 3.7], and 2.0 [1.7, 2.2] months, respectively.ConclusionsPatients in a real-world setting treated with NAPOLI-1-based liposomal irinotecan doublet regimens at academic centers were older with poorer performance status compared to trial patients yet had similar outcomes and efficacy. Furthermore, liposomal irinotecan was frequently used in the 3L+ setting where no treatment has been approved and provided clinical benefit.

There are questions surrounding the real-world effectiveness of chemotherapeutic treatments for pancreatic ductal adenocarcinoma. This literature review compared the clinical characteristics and outcomes of available real-world evidence (RWE) for liposomal irinotecan in combination with 5-fluorouracil (5-FU) and leucovorin (LV), a treatment regimen indicated for patients with metastatic pancreatic ductal adenocarcinoma (mPDAC) who previously progressed on gemcitabine-based therapy. A targeted literature search was conducted in the PubMed Central® and Embase® databases to identify available RWE regarding patients with mPDAC receiving liposomal irinotecan published within the last 5 years (January 2014–September 2019). Data were extracted for prior lines of therapy, performance status, overall survival (OS), progression-free survival (PFS), duration of exposure, and adverse events. Six studies met inclusion criteria. A comparison of baseline patient characteristics and results with the included evidence reveals a clinically fragile, real-world patient population in terms of age (range: 61–68), prior lines of therapy with 34–61% of patients receiving ⩾2 lines of lines of prior therapy and performance status [49.8–100% of patients with Eastern Cooperative Oncology Group (ECOG) 0–1]. Studies observed wide OS (range: 5.3–9.4 months) and similar PFS (range: 2.3–4.1 months), with two studies measuring duration of exposure (7.3 weeks, 3.1 months). Patients analyzed by RWE studies tended to be older with significant disease progression, poor performance status, and more heavily pretreated compared with the phase III registrational trial (NAPOLI-1). Despite this, patients treated with liposomal irinotecan + 5-FU/LV therapy had similar outcomes as those in NAPOLI-1.

e20563 Background: MPM is a highly aggressive pleural tumor associated with asbestos exposure and with limited survival despite systemic therapy. Histology is a prognostic factor and recently CheckMate 743 trial demonstrated survival benefit of immunotherapy in first line with some differences in the efficacy of chemotherapy according to histology. However, randomized trials who led to the approval of antifolate in mesothelioma did not include analysis of outcomes by histology. The objective of this study is to characterize the impact of chemotherapy according to histology in p with MPM at our institution. Methods: We review 189 MPM p diagnosed at Vall d´Hebron University Hospital between November 2002 and April 2020. Associations between clinical variables and outcome were assessed with Cox regression models and survival data were calculated by the Kaplan-Meier method. Results: Patient’s characteristics: median age 68 years (y) (45-88 y), males: 70%, performance status (PS)1: 69%, asbestos exposure: 75%, epithelioid subtype: 76%. First line chemotherapy was offered to 85% of p (66% cisplatin-pemetrexed and 27% carboplatin-pemetrexed). Median overall survival (OS) in overall population was 21.3 m (95%CI17.2-24.3). Epithelioid histology, PS 0, neutrophil-lymphocyte ratio <5 and treatment with cisplatin vs carboplatin were associated with significant improvements in OS (p<0.001). When we analyzed the survival of patients who received first line chemotherapy according to histology, we found that patients with epithelioid tumors had better PFS and OS. Median PFS for p with epithelioid tumors treated with chemotherapy in first line was 4.8 m versus 3.6 months non-epithelioid (HR1.5 CI95% 1.1-2.3; p=0.03). OS of epithelioid p treated with first line chemotherapy was 26.7 m versus 15.0 m non-epithelioid patients (HR2.25 CI95% 1.4-3.4; p<0.001). We analyzed if the differences in survival according to histology were due to type of systemic treatment received (Table). Conclusions: In our series, p with non-epithelioid tumors presented worse prognosis. We confirmed histology is a prognostic factor with better OS for p with epithelioid tumors. Moreover, we demonstrated better efficacy of chemotherapy in epithelioid tumors, although histology is not a predictive factor for the platinum agent sensitivity (p of interaction PFS=0.09, p of interaction OS= 0.65).[Table: see text]

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.

Background: NSCLC is the leading cause of cancer-related mortality worldwide. Recently reported clinical trials have firmly established the role of PD-1 and PD-L1 inhibitors in the treatment of patients (pts) with metastatic NSCLC (mNSCLC). We have established the prospective, observational, real-world Advanced Non-Small Cell Lung Holistic Registry (ANCHoR) to understand how the advent of immunotherapy impacts treatment choices and clinical outcomes. Objectives: The aim of this analysis is to measure the impact of immunotherapy on the treatment choice for the first-line treatment of mNSCLC and to determine the link between PD-L1 expression and the treatment choices made in routine clinical practice at the MD Anderson Cancer Center (MDA). Methods: From May 1, 2017, to June 30, 2018, English-speaking pts with mNSCLC at MDA who provided written informed consent were enrolled in ANCHoR and longitudinally followed. The PD-L1 testing rates were captured and the treatment decisions made were also captured and tabulated. The time of data cutoff for this study is June 30, 2018. Results: Of the 296 pts enrolled in the registry at the time of data cutoff, there were 49.7% males, 82.1% white, 45.9% ≥65 years old, 69.3% smokers, 83.1% with an initial stage IV diagnosis, 87.2% with nonsquamous histology, 36.1% with bone metastasis, 29.4% with brain metastasis, 43.2% with 0–1 performance status, and 21.6% with a known EGFR or ALK mutation. A total of 233 pts had been tested for PD-L1 (78.7%). Predominant reasons for not testing (63 pts) include not having available tissue (26 pts) or the test was not requested by the physician (31 pts). As of June 30, 2018, 38.5% of patients received immunotherapy as first-line therapy either as a single agent (18.9%, 56 pts) or in combination with chemotherapy (19.6%, 58 pts). Only 35.8% of the patients received platinum doublet chemotherapy alone. Two pts received chemotherapy combined with an anti-angiogenesis agent (0.68%). Targeted therapy was utilized either as a single agent (20.6%) or in combination with immunotherapy (2.4%). Conclusion: Immunotherapy is now utilized as a single agent or in combination in more than one-third of patients with mNSCLC. These numbers are expected to increase as data from recently reported studies get incorporated into common clinical practice. Compared to historic experience, there has been a dramatic decline in the use of chemotherapy with an anti-angiogenesis agent.

Abstract Abstract 4591 Introduction: Clinicians and investigators appreciate the value of measuring HRQOL for monitoring CLL and the impact of treatments, and commonly use ECOG performance status (PS) and clinician-reported patient fatigue as surrogates for HRQOL in clinical practice. However, limited data exist on the relationships between PS, fatigue, and HRQOL in CLL patients (pts) undergoing treatment in clinical practices. We examined the associations between these measures and 3 psychometrically validated, patient-reported, HRQOL instruments: the Brief Fatigue Inventory (BFI), EQ-5D, and Functional Assessment of Cancer Therapy-Leukemia (FACT-Leu). Methods: Data were collected as part of Connect CLL®, a prospective observational registry initiated in March 2010 involving US practices. Data on pt demographics and clinical characteristics were provided by clinicians. HRQOL was self-reported by pts at enrollment using the BFI, EQ-5D, and FACT-Leu. Mean BFI, EQ-5D and FACT-Leu scores were analyzed by ECOG PS and clinician-reported fatigue. Differences in HRQOL scores between sub-cohorts were assessed by ANOVA. Results: HRQOL data were reported by 604 pts enrolled from 10 academic, 148 community, and 3 government centers. Pts were predominantly male (62%) and white (90%); mean age was 70 (standard deviation 11) years. BFI data (scale: 0 [no fatigue] - 10 [worst fatigue]) indicated that on average pts report that global fatigue, fatigue severity and fatigue-related interference worsen by ECOG severity (Table 1) and are statistically associated with clinician-reported fatigue (Table 2). Mean EQ-5D overall HRQOL as measured by a Visual Analogue Scale (VAS) from 0 (worst) to 100 (best) worsens by ECOG severity and is significantly worse in pts with fatigue. Mean EQ-5D domain scores (scale: 1 [no problem], 2 [some problems], 3 [incapacity]) indicated that pain/discomfort, mobility and usual activities increase in severity as ECOG worsens and in pts with fatigue. FACT-Leu domains except social/family were statistically worse with worse ECOG PS and in pts with fatigue. Conclusions: Initial results from Connect CLL® indicate that HRQOL worsens with worsening ECOG PS, especially in physical / functioning domains, pain/discomfort, and mobility, and worsens across multiple domains among pts whose physicians reported fatigue. Future analyses should be conducted on how HRQOL, PS and fatigue may change over time with changes in CLL, and how they are influenced by therapies. These results may serve as baseline reference.

5037 Background: BTT can delay symptomatic progression in cancer pts with bone metastases. In a post hoc analysis, we assessed the impact of concomitant BTT on outcomes in a recent large, multinational study in mCRPC pts without prior ctx. Methods: COU-AA-302 was a phase III trial in asymptomatic/mildly symptomatic pts with progressive mCRPC and no prior ctx. 1,088 pts were stratified by ECOG performance status (ECOG-PS, 0 vs 1) and randomized 1:1 to AA 1 g or placebo QD, plus prednisone 5 mg BID. Radiographic progression-free survival (rPFS) and overall survival (OS) were primary end points; secondary end points were times to opiate use, ctx, ECOG-PS deterioration, and PSA progression. The effect of concomitant use of BTT on all end points was assessed retrospectively using a stratified Cox regression model with factors for treatment, concomitant BTT, interaction of treatment and BTT, and baseline covariates. All data were obtained from a prespecified interim analysis at 55% OS events. Results: Median follow-up at the time of analysis was 27.1 mos. Among intent-to-treat (ITT) pts, 184/546 AA and 169/542 P pts received concomitant BTT for treatment of bone metastases, either zoledronic acid (n = 330), other bisphosphonates (n = 16), denosumab (n = 22), and/or other BTT (n = 5). In these pts, concomitant BTT use was associated with improved OS, time to opiate use for cancer pain, and time to ECOG-PS deterioration (Table). Results were similar in a sensitivity analysis including only ITT pts with bone metastases at baseline. Conclusions: In this post hoc, exploratory analysis, concomitant BTT use was associated with delayed symptomatic progression in asymptomatic/mildly symptomatic mCRPC pts. This potential clinical benefit should be investigated in prospective studies. Clinical trial information: NCT00887198. [Table: see text]

e15007 Background: The CORRECT trial demonstrated overall survival benefits of regorafenib monotherapy in patients with metastatic colorectal cancer (CRC) who were refractory to prior chemotherapy and biological therapy. However, stringent criteria used to determine treatment eligibility in the trial setting may limit its external validity in the real world. We aimed to examine treatment attrition rates and eligibility of regorafenib in routine clinical practice. Methods: All patients diagnosed with metastatic CRC between 2009 and 2014 who received 2 or more lines of systemic therapy at the British Columbia Cancer Agency were identified. During the study timeframe, cetuximab (cmab) and panitumumab (pmab) were only used in the chemo-refractory setting. Data on clinical factors, pathological variables and outcomes were ascertained and analyzed. Eligibility was defined based on criteria outlined in the CORRECT trial. Results: A total of 391 patients were included among whom only 39% were considered eligible for regorafenib. Median age was 61 (range 22-84) years. 247 (63%) were men, 305 (78%) were Caucasian, and 237 (60%) had a colonic primary. The disease burden at diagnosis was high: 267 (81%) had lymph node involvement, and 225 (59%) had distant metastases. In patients previously treated with cmab, main reasons for regorafenib ineligiblity were Eastern Cooperative Oncology Group performance status (ECOG PS) > 1 (26.9%), aspartate aminotransferase (AST) > 2 x upper limit of normal (ULN) (6.5%), and arterio-venous thrombotic or embolic events in the preceding 6 months (6.5%). In the group treated with pmab previously, main reasons for ineligibility were ECOG PS > 1 (46.6%), total bilirubin > 1.5 x ULN (14.1%), and thrombotic or embolic events in the past 6 months (5.7%). Additional analyses showed that regorafenib-eligible patients had increased median overall survival compared to ineligible patients (44.0 vs 37.1 months, P= 0.028). Conclusions: The strict trial eligibility criteria disqualified the majority of real world patients with metastatic CRC for regorfenib. As ineligibility predicts poorer outcomes, trials aimed at serving protocol-ineligible patients are warranted.

Abstract Background Treatment of multiple myeloma (MM) has changed significantly in recent years with the availability of novel agents including monoclonal antibodies (mAbs), proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs) such as lenalidomide. Despite lenalidomide becoming a standard of care across all lines of myeloma therapy, the population of MM patients refractory to lenalidomide and their real-world clinical management has been poorly studied so far, especially outside the reality of interventional clinical trials (Moreau et. al. Blood Cancer J. 2019). With these considerations in mind, we have performed a retrospective study using two databases to better understand treatment patterns and outcomes of MM patients who were treated with lenalidomide and subsequently became refractory to it. This builds on work previously conducted at other data sources (Willenbacher et. al. EHA Library 2020). Aims The objective of this study was to describe the treatment patterns and outcomes of MM patients exposed to lenalidomide, with a focus on refractory patients, as defined by IMWG (International Myeloma Working Group) consensus, in a real-world clinical setting. Methods The study utilised databases from two participating members of the IQVIA MM real world evidence network: University Hospital Frankfurt (Frankfurt) (Germany) and Portuguese Oncology Institute of Porto (IPO-Porto) (Portugal). Since the native format of databases from participating sites differs, key concepts were harmonised based on pre-agreed definitions. The study population included patients with an initial diagnosis of MM between 01/01/2012 and 31/12/2018 based on the IMWG criteria, were 18 years old or older at the time of diagnosis and received two or more cycles of lenalidomide treatment, alone or in combination, at any dose, excluding patients who only received lenalidomide as maintenance therapy. Patients were defined as refractory to lenalidomide treatment if they progressed on treatment or within 60 days following the end of lenalidomide treatment (excluding maintenance setting). Kaplan-Meier curves were produced to evaluate the time to next treatment (TTNT) and overall survival (OS) for lenalidomide exposed and lenalidomide refractory patients. TTNT was defined as the time between the start date of the line of lenalidomide therapy and the start date of the next line of therapy (LoT) or death due to any cause. OS was defined as the time between the start date of the line of lenalidomide therapy and death due to any cause. Results The cohort included 55 and 42 MM lenalidomide-exposed patients from Germany and Portugal respectively. In Germany, 80% were initially exposed to the lenalidomide in LoT 1, whilst in Portugal 71% received initial lenalidomide treatment in LoT 3. In Portugal, following lenalidomide refractoriness, the majority (78%) of patients received chemotherapy and steroids only whilst in Germany a range of treatment types was observed (mAb-based 33%; PI-based 11%; PI/IMiD combo 11%; mAb/IMiD combo 11%; chemotherapy and steroids only 11%; other 22%). The median OS in months for lenalidomide-exposed refractory patients was 7 in Portugal and 31 in Germany; the median OS for non-refractory patients was 40 in Portugal and was not reached in Germany. The median TTNT in months for lenalidomide-exposed refractory patients was 4 in Portugal and 15 in Germany; the median TTNT for non-refractory patients was 14 in Portugal and 53 in Germany. Conclusion The analysis of real-world data across two countries, showed heterogeneity in lenalidomide treatment patterns, with first exposure typically occurring in LoT 1 or 3. This has led to differences in the calculated TTNT and OS, and as such the results between the two countries cannot be directly compared. The OS from diagnosis for this cohort is being assessed and will provide an insight on the impact of different treatment pathways. Patients who became refractory to lenalidomide moved on to their next treatment much quicker after exposure vs patients who were not refractory to lenalidomide; similarly, patients who became refractory to lenalidomide had shorter OS than patients who were not refractory. Patients typically became refractory early in their treatment journey, indicating a growing population with unmet medical needs. Figure 1 Figure 1.
