e16025 Background: While clinical trials have affirmed benefit of IO for mUC, limited real-world evidence exists to describe the current treatment landscape and clinical outcomes. This study evaluated these trends in a network of community oncology practices, the US Oncology Network (USON). Methods: This was a retrospective study of adult mUC pts who initiated IO regardless of PD-L1 expression in the first- (1L cohort) or second-line (2L cohort) setting between 5/1/2016-1/31/2018. Using data from USON’s electronic heath record, descriptive and Kaplan-Meier analyses were conducted to evaluate baseline characteristics, treatment patterns and clinical outcomes. Results: Among the 254 pts in the 1L cohort, median (range) age at IO initiation was 74 (42, 90+), 71% were male, 77% were Caucasian, and 18.1% and 5.9% had ECOG performance status (PS) 2 and 3/4, respectively. Among the 179 pts in the 2L cohort, median (range) age at IO initiation was 71 (29, 90+), 76% were male, 76% were Caucasian and 20.7% and 2.2% had ECOG PS 2 and 3/4, respectively. Nearly all pts received IO monotherapy. Median (range) follow-up durations from IO initiation were 4.3 (0, 22; 1L cohort) and 3.6 (0, 19; 2L cohort) months (mo), during which time 39% (1L cohort) and 37% (2L cohort) of pts died. Median overall survival (95% confidence interval [CI]) was 9.9 (7.5, 15.7) mo for the 1L IO cohort and 8.3 (6.4, not reached) mo for the 2L IO cohort. Six-mo survival probabilities (95% CI) were 61.6% (54.5%, 67.9%; 1L cohort) and 60.7% (51.4%, 68.8%; 2L cohort). In total, 52.8% of 1L pts and 53.6% of 2L pts were alive and did not advance to next line of therapy, and 11% of 1L and 13% of 2L cohort pts advanced to the next line of therapy. Median (95% CI) treatment durations were 2.3 (1.9, 3.0) and 3.3 (2.7, 3.9) mos for the 1L and 2L cohorts, respectively. Six-mo ongoing treatment probabilities (95% CI) were 28.9% (23.3%, 34.7%; 1L cohort) and 34.0% (26.1%, 42.1%; 2L cohort). Conclusions: Outcomes of real-world mUC pts receiving IO were as expected, with majority of pts alive and a small minority receiving post-IO therapy. Future research should examine how pt and tumor (PD-L1 expression) characteristics influence treatment and outcomes.

457 Background: Benefit of IO (PD1 and PD-L1 inhibitors) for mUC was observed in clinical trials but real-world evidence for benefit and clinical outcomes is limited. Methods: This was a retrospective study of adult pts with mUC who initiated IO regardless of PD-L1 expression in the first- (1L cohort) or second-line (2L cohort) setting between 5/1/2016-1/31/2019 in the US Oncology Network (USON), a network of community oncology practices. Descriptive and Kaplan-Meier analyses to evaluate baseline characteristics, treatment patterns and clinical outcomes were conducted using data from USON’s electronic heath record. Results: Among 393 pts in the 1L cohort, median (range) age at IO initiation was 77 (42, 90+), 74% were male, 69% were White, and 19.1% and 4.1% had ECOG performance status (PS) 2 and 3/4, respectively. Among the 366 pts in the 2L cohort, median (range) age at IO initiation was 70 (29, 90+), 74% were male, 71% were White, and 19.7% and 1.4% had ECOG PS 2 and 3, respectively. Median (range) follow-up durations from IO initiation were 4.2 (0, 34.1; 1L cohort) and 4.1 (0, 31.3; 2L cohort) months (mo), during which time 43.1% (1L cohort) and 44.4% (2L cohort) of pts died. Median overall survival (OS) from IO initiation (95% confidence interval [CI]) was 10.6 (9.7, 13.2) mo for the 1L cohort and 9.4 (7.1, 11.5) mo for the 2L cohort; 1-year survival probabilities (95% CI) were 46.6% (40.1%, 52.8%; 1L cohort) and 43.4% (36.8%, 49.8%; 2L cohort). By the end of the follow-up, 48.1% of 1L pts and 47.8% of 2L pts were alive and did not advance to next line of therapy, and 13.5% of 1L and 13.4% of 2L cohort pts advanced to the next line of therapy. Median (95% CI) treatment durations were 2.6 (2.1, 2.9) and 2.8 (2.2, 3.5) mo for the 1L and 2L cohorts, respectively; 6-mo ongoing treatment probabilities (95% CI) were 26.6% (22.2%, 31.2%; 1L cohort) and 31.4% (26.4%, 36.4%; 2L cohort). Conclusions: OS of pts in the real world receiving 1L and 2L IO appears consistent with clinical trial results, although survival follow-up is limited. A minority of pts received post-IO therapy. Future research should examine influence of pt characteristics and PD-L1 expression on treatment choice and outcomes.

e21015 Background: PD-1 monoclonal antibodies are promising immunotherapies approved for treatment of patients (pts) with advanced melanoma. As the first US FDA approved PD-1 antibody, pembrolizumab (pembro) has demonstrated efficacy and safety in clinical trial settings. However, patterns of real world utilization and pt outcomes associated with pembro are limited. Methods: Adult pts with advanced melanoma who initiated pembro between 9/1/ 2014-3/31/2016 were identified retrospectively fromelectronic health records (EHR) of McKesson Specialty Health and followed through 9/ 30/2016. Pts in clinical trials were excluded. Demographic, disease, treatment characteristics and reasons for treatment discontinuation of pembro were abstracted from structured data elements of the EHR with further supplementation of unstructured data within the patient chart (progress notes, radiology scan reports). Overall survival (OS) and physician-reported progression free survival (PFS) from pembro initiation were analyzed using Kaplan Meier analysis. Results: 182 pts, with a median follow-up of 9.9 mos (range = 0.0-25.0), were included. Median age at pembro initiation was 66.0 yrs; 30.8% had an elevated lactate dehydrogenase (LDH); 23.6% had brain metastases and 65.4% had an ECOG performance status of 0 or 1. The most common reason for pembro discontinuation was progression (45.5%) followed by treatment-related toxicity (24.4%). In the overall population, median PFS from pembro initiation was 4.2 mos (95% CI = 3.2-5.3). Median OS was 19.4 mos (14.0-NR) with 12 and 24-month survival probabilities of 61.4% (95% CI = 53.4-68.5) and 43.9% (95% CI = 31.1-55.9). In multivariable analyses, characteristics predictive of worse survival included receipt of pembro at a later line of therapy (HR = 3.36, p = 0.0013 for 3L+), presence of brain metastases (HR = 2.67, p = 0.0007) and elevated LDH (HR = 4.10, p < 0.0001). Conclusions: The study results are consistent with those from pembro clinical trials (KeyNote001) and are in support of the effectiveness of pembro in real world treatment of advanced melanoma. Presence of brain metastases, elevated LDH, and use of pembro 3L+ were associated with worse survival outcome.

9004 Background: Given the importance of molecular testing and targeted therapy for mNSCLC, the MYLUNG (Molecularly Informed Lung Cancer Treatment in a Community Cancer Network) consortium pragmatic study assessed real-world biomarker testing rates and turnaround times (TAT) within The US Oncology Network of over 1,000 providers across the United States. Methods: This was a retrospective observational chart review study of pts with mNSCLC initiating first-line (1L) systemic therapy between 04/01/2018 and 03/31/2020. iKnowMed electronic health records were used to examine timing of biomarker testing: before 1L therapy (cohort 1), after 1L therapy (cohort 2) or no testing (cohort 3). We assessed testing rates for ALK, BRAF, EGFR, ROS1, and PD-L1; use of full next-generation sequencing panel (NGS); time from mNSCLC diagnosis (dx) to 1L therapy; TAT from biomarker orders to results; and time from mNSCLC dx to test results. Results: We identified 3474 adults. Median age was 69 years (range 23-90), 51% female, 74% with adenocarcinoma and 76% with a documented ECOG performance status of 0 or 1. Testing rates are shown in table: 90% of pts had at least one biomarker test and 46% received all 5 biomarker tests. Changes in testing rates from 2018 to 2020 were 51% to 59% for BRAF, 71% to 71% for EGFR, 71% to 70% for ALK, 69% to 67% for ROS1, 82% to 84% for PD-L1, and 42% to 49% for pts tested for all 5 biomarkers. NGS testing increased from 33% to 44% (p<0.0001). The median (interquartile range [IQR]) time from mNSCLC dx to 1L therapy for all pts was 35 (22, 55) days. Median (IQR) TAT from biomarker testing orders to results ranged from 10 (6, 17) to 15 (10, 22) days for the individual biomarkers; and time from mNSCLC dx to biomarker results ranged from 14 (7, 26) to 21 (12, 36) days by biomarker. Conclusions: This real-world study showed that most pts received at least one biomarker test prior to 1L, but <50% received all 5 tests. NGS testing occurred in <50% of pts but increased over the periods examined. Median time from dx to 1L therapy was about 5 weeks and TAT from orders to results about 2 weeks. Analyses by histology and other trends will be reported. These data will be compared to the next phase of the MYLUNG study, which will evaluate contemporary ordering practices and TATs prospectively[Table: see text]

Liposomal Irinotecan

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 &lt;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.

71 Background: For patients with refractory metastatic colorectal cancer (mCRC) treatment with Trifluridine/Tipiracil, also known as TAS-102, improves overall survival. In Australia, TAS-102 was initially made available locally through patients self-funding, later via an industry sponsored Medicine Access Program (MAP) and then via the Pharmaceutical Benefits Scheme (PBS). This study aims to investigate the efficacy and safety of TAS-102 in real world Australian population. Methods: A retrospective analysis of prospectively collected data from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry was undertaken. The characteristics and outcomes of patients receiving TAS-102 were assessed and compared to all TRACC patients and those enrolled in the registration study (RECOURSE). Results: Across 13 sites, 107 patients were treated with TAS-102 (non-PBS n = 27, PBS n = 80), The median number of patients per site was 7 (range: 1-17). The median age was 60 years (range: 31-83), compared to 67 for all TRACC patients and 63 for RECOURSE. Comparing registry TAS-102 and RECOURSE patients, 75% vs 100% were ECOG performance status 0-1, 74% vs 79% had initiated treatment more than 18 months from diagnosis of metastatic disease and 39% vs 49% were RAS wild type. Median time on treatment was 10.4 weeks (range: 1.7-32). Median clinician assessed progression-free survival was 3.3 compared to RECIST defined PFS of 2 months in RECOURSE study, while median overall survival was the same at 7.1 months. Two patients (2.3%) had febrile neutropenia and there were no treatment-related deaths in the real-world series, where TAS102 dose at treatment initiation was at clinician discretion. In the RECOURSE study there was a 4% febrile neutropenia rate and one treatment-related death. Conclusions: TRACC registry patients treated with TAS102 were younger than both TRACC patients overall and those from the RECOURSE trial. Less strict application of RECIST criteria and less frequent imaging may have contributed to an apparently longer PFS. However overall survival outcomes achieved with TAS102 in real world patients were comparable to findings from this pivotal trial with an acceptable rate of major adverse events.

e18004 Background: Anti-PD1 checkpoint inhibitors (ICI) represent an established standard of care for patients with recurrent/metastatic head & neck squamous cell carcinoma (RMHNSCC). Landmark studies excluded patients with ECOG performance status (PS) ≥ 2; the benefit of ICI in this population is therefore unknown. Methods: We retrospectively reviewed RMHNSCC patients who received at least 1 dose of ICI at our institution. Demographic data and clinical outcomes were obtained; the latter included objective response to ICI (ORR), physician-documented CTCAE grade 2+ toxicity (irAE), and any unplanned hospitalization within 100-days of last ICI dose (UH). Associations between demographic data and clinical outcomes were explored using both uni- and multivariate analysis. Overall survival (OS) was estimated using a Cox proportional hazards model; ORR, irAE, and UH were evaluated with logistic regression. This project was approved by our institutional IRB. Results: We identified 152 RMHNSCC patients who were treated with ICI between 1/2013 and 1/2019. ECOG PS was 0 in 42 (27%), 1 in 75 (50%), 2 in 27 (18%), 3 in 2 (1%), and unknown in 6 (4%) patients. The median age was 61 (range: 25 - 90). 124 (82%) were male, 124 (82%) were white, and 69 (45%) were never-smokers. The most common primary sites were the oropharynx (n = 59, 40%), oral cavity (n = 39, 26%), nasopharynx (n = 11, 7%), and larynx (n = 10, 6%). 54 (36%) were p16+ oropharynx cancers. CPS score was available in 10 (6.6%). Single agent ICI was received by 118 (77%) patients. 66 (44%) had a documented irAE and 54 (36%) had an UH. A multivariate model for OS containing PS, smoking status and HPV status showed a strong association between inferior OS and ECOG 2/3 compared to 0/1 (p < 0.001; HR = 3.30, CI = 2.01-5.41), as well as former (vs. never) smoking status (p < 0.001; HR = 2.17, CI = 1.41-3.35). Current smoking (p = 0.25) did not reach statistical significance. On univariate analysis, poor PS was associated with inferior ORR (p = 0.03; OR = 0.25, CI = 0.06-0.77) and increased UH (p = 0.04; OR = 2.43, CI = 1.05—5.71). There was no significant association between irAE and any patient characteristic. Conclusions: We observed inferior overall survival among ICI-treated RMHNSCC patients with ECOG 2/3 in our single-institution, retrospective series. Our findings help frame discussion of therapeutic options in this poor-risk population. Further study must be done to determine which interventions are of greatest benefit for RMHNSCC patients with declining performance status.

Quantitative Bias Analysis

IntroductionThe German health technology assessment (HTA) rejected additional benefit of alectinib for second line (2L) ALK+ NSCLC, citing possible biases from missing ECOG performance status data and unmeasured confounding in real-world evidence (RWE) for 2L ceritinib that was submitted as a comparator to the single arm alectinib trial. Alectinib was approved in the US and therefore US post-launch RWE can be used to evaluate this HTA decision.MethodsWe compared the real-world effectiveness of alectinib with ceritinib in 2L post-crizotinib ALK+ NSCLC using the nationwide Flatiron Health electronic health record (EHR)-derived de-identified database. Using quantitative bias analysis (QBA), we estimated the strength of (i) unmeasured confounding and (ii) deviation from missing-at-random (MAR) assumptions needed to nullify any overall survival (OS) benefit.ResultsAlectinib had significantly longer median OS than ceritinib in complete case analysis. The estimated effect size (Hazard Ratio: 0.55) was robust to risk ratios of unmeasured confounder-outcome and confounder-exposure associations of <2.4.Based on tipping point analysis, missing baseline ECOG performance status for ceritinib-treated patients (49% missing) would need to be more than 3.4-times worse than expected under MAR to nullify the OS benefit observed for alectinib.ConclusionsOnly implausible levels of bias reversed our conclusions. These methods could provide a framework to explore uncertainty and aid decision-making for HTAs to enable patient access to innovative therapies.

BackgroundPatients with non–small cell lung cancer (NSCLC) and a poor Eastern Cooperative Oncology Group Performance Status (ECOG PS) have been excluded from phase III immunotherapy clinical trials. We sought to evaluate clinical outcomes to first-line pembrolizumab in patients with advanced NSCLC, a PD-L1 Tumor Proportion Score (TPS) of ≥50%, and an ECOG PS of 2.MethodsWe performed a multicenter retrospective analysis of patients with metastatic NSCLC and a PD-L1 TPS of ≥50% (negative for genomic alterations in EGFR and ALK) who received treatment with first-line pembrolizumab. Clinical outcomes were compared in patients based on ECOG PS.ResultsAmong the 234 patients, 83.3% (n=195) had an ECOG PS of 0 or 1, and 16.7% (n=39) had an ECOG PS of 2. The baseline clinicopathological characteristics were balanced between the ECOG PS 0–1 vs 2 groups in terms of age, sex, tobacco use, histology, KRAS mutation status, presence of other potentially targetable driver mutations (BRAF, MET, HER2, RET), presence of brain metastases, and PD-L1 TPS distribution. Compared with patients with an ECOG PS of 0 or 1, patients with an ECOG PS of 2 had a significantly lower objective response rate (43.1% vs 25.6%; p=0.04), a numerically shorter median progression-free survival (6.6 months vs 4.0 months; HR 0.70 (95% CI 0.47 to 1.06); p=0.09), and a significantly shorter median overall survival (20.3 months vs 7.4 months; HR 0.42 (95% CI 0.26 to 0.68); p<0.001). On disease progression, patients with an ECOG PS of 2 were significantly less likely to receive second-line systemic therapy compared with patients with an ECOG PS of 0–1 (65% vs 22.2%, p=0.001).ConclusionsA subset of patients with NSCLC and an ECOG PS of 2 can respond to first-line pembrolizumab. However, clinical outcomes in this population are often poor and use of second-line systemic therapy is infrequent.
