Abstract
Armed antibodies, of which are representative antibody-drug conjugate(ADC)and radioimmunotherapy(RIT), are attracting attention as next-generation antibody drugs with high efficacy and low side effects. Armed antibodies require clinically optimized adaptation and development strategies, in addition to the fusion of basic technologies such as organic chemistry, protein chemistry, imaging technology, structural biology, and biomarker research. In armed antibodies, the antibody is only a carrier for deliver and its therapeutic effect affects the specificity/strength of the payload, which is the effector agent for target molecules on cell surface. An ADC with a bystander effect is a promising drug for solid tumors with heterogeneous target molecule expression. Aside from the next-generation ADC DS8201, new ADCs are being developed at an accelerated pace, demonstrating new therapeutic possibilities. In the future, it will be necessary to optimize predictors of therapeutic effect based on the MOA of ADC.

Abstract
2565 Background: Approval of pembrolizumab for the treatment of unresectable or metastatic MSI-H/dMMR solid tumors that have progressed on prior therapy was supported by data from KEYNOTE-158 (NCT02628067). At the data cutoff of Dec 6, 2018, the ORR was 34.3% among 233 patients (pts) with MSI-H/dMMR solid tumors enrolled in all cohorts of KEYNOTE-158, 77.6% had duration of response (DOR) ≥24 mo, median PFS was 4.1 mo, and median OS was 23.5 mo. We present results from 351 pts enrolled in KEYNOTE-158 cohort K at the data cutoff of Oct 5, 2020. Methods: Cohort K of this phase 2, open-label study enrolled adults with any previously treated advanced noncolorectal MSI-H solid tumor, measurable disease per RECIST v1.1, and ECOG PS of 0–1. MSI-H/dMMR status was assessed locally from a tumor tissue sample and defined as ≥1 of 4 MMR proteins absent by immunohistochemistry or as ≥2 allelic loci size shifts of 5 microsatellite markers by PCR. Pts received pembrolizumab 200 mg Q3W for up to 35 cycles or until PD, unacceptable toxicity, investigator decision, or withdrawal of consent. The primary endpoint was ORR per RECIST v1.1 by blinded independent central review (BICR). Secondary endpoints were DOR and PFS per RECIST v1.1 by BICR, OS, and safety. Efficacy was assessed in all pts who received ≥1 dose of treatment with ≥6 mo follow-up; safety was assessed in all treated pts. Results: 351 pts were enrolled in KEYNOTE-158 cohort K across multiple tumor types, including endometrial (22.5%), gastric (14.5%), small intestine (7.4%), ovarian (7.1%), cholangiocarcinoma (6.3%), and pancreatic (6.3%). 41.0% had 1 prior line of therapy; 55.6% had ≥2 prior lines. Median time from first dose to database cutoff (Oct 5, 2020) was 37.5 (range, 0.2–55.6) mo; 16.0% were continuing treatment. The ORR among the 321 eligble pts was 30.8% (CR, 27; PR, 72); median DOR was 47.5 mo (Table). Treatment-related AEs occurred in 64.7% of pts (grade 3–5, 12.0%), led to discontinuation in 6.6%, and led to death in 3 pts (myocarditis, pneumonia, and Guillain-Barre syndrome). Immune-mediated AEs and infusion reactions occurred in 20.2% of pts (grade 3–4, 4.3%) and led to death in 2 pts with no other contributing factors (myocarditis [AE start, day 26; death, day 33] and Guillain-Barre syndrome [AE start, day 22; death, day 41]). Conclusions: Pembrolizumab demonstrated a high ORR (30.8%), durable clinical benefit, and a manageable safety profile in this heavily pretreated advanced MSI-H/dMMR noncolorectal pan-tumor population.

Abstract
4081 Background: FGFR alts (mutations and fusions) have been reported in multiple advanced solid tumors at varying frequencies. These alts may function as oncogenic drivers of disease independent of the underlying tumor type. RAGNAR is an ongoing phase 2, histology-agnostic trial investigating the efficacy and safety of erdafitinib, a selective pan-FGFRi, in patients (pts) with advanced solid tumors and FGFR alts. Little is known about the incidence, diversity or predominant FGFR alts across solid tumors in the clinical setting. Here, we provide an update on molecular screening and enrollment in the primary analysis population. Methods: Pts with advanced solid tumors were molecularly screened for eligible FGFR alts via central next generation sequencing (NGS) or review of local NGS reports. Underlying tumor type, FGFR alts, demographics and key disease characteristics were collected at baseline. Results: From Nov 2019 to Jan 2021, 5758 pts were molecularly screened (central or local) in 15 countries. 191 pts (3.3%) fulfilled primary analysis molecular eligibility criteria; 110 pts were enrolled. Among pts enrolled, 14 (12.7%) had central screening and 96 (87.3%) had local NGS reports. Eligible FGFR alts were identified in 19 tumor types, including rare cancers and ones (eg, pancreatic) with a very low prevalence of FGFR alts in genomic databases (Table). Median age was 57 y, and 19 pts (17.3%) were < 40 y. Gender distribution was even. Conclusions: Findings from molecular screening in the RAGNAR study indicate a wide range of FGFR-altered tumor types, including a notable number of cancers where eligible FGFR alts were considered exceedingly rare (eg, pancreatic). These results demonstrate the feasibility of conducting clinical trials on pts with rare genetic alts by adopting a histology-agnostic design and using both central testing and local NGS reports for molecular screening. This approach also helps investigate rare tumors, where histology-specific trials are challenging. Efficacy and safety results from the RAGNAR study will help define the benefit of erdafitinib in FGFR-altered advanced solid tumors. Clinical trial information: NCT04083976. [Table: see text]

Randomized, double-blind, placebo (PL)-controlled, phase III trial of pimitespib (TAS-116), an oral inhibitor of heat shock protein 90 (HSP90), in patients (pts) with advanced gastrointestinal stromal tumor (GIST) refractory to imatinib (IM), sunitinib (SU) and regorafenib (REG).

Abstract
11524 Background: Pimitespib (PIM) is a novel class of orally active selective HSP90 inhibitors. KIT and PDGFRA are clients of HSP90 for their functional stability; therefore, HSP90 is a rational therapeutic target on GIST in pts with acquired resistance, such as secondary mutation in KIT, to approved tyrosine kinase inhibitors. A phase II trial showed clinical activity of PIM in pts with advanced GIST refractory to standard treatments whose medical need remains unmet. This phase III trial evaluated the efficacy and safety of PIM for this unmet clinical need. Methods: Eligible pts had histologically confirmed advanced GIST refractory to IM, SU, and REG, ≥1 measurable lesion, and ECOG performance status 0 or 1. Pts were randomized 2:1 to receive either PIM 160 mg once daily on a 5-days-on/ 2-days-off schedule or PL. Pts eligible for unblinding at the time of progressive disease were allowed to crossover to open-label PIM. The primary endpoint was progression-free survival (PFS) by blinded central radiological review based on modified RECIST 1.1. Secondary endpoints included overall survival (OS), PFS in the pts crossed over to PIM (secondary PFS), and safety. Crossover-adjusted OS was derived using the rank preserving structural failure time (RPSFT) model. Exploratory endpoints included pharmacogenomics (PGx). Results: From Oct 2018 to Apr 2020, 86 pts were randomized to receive either PIM (n = 58) or PL (n = 28). Baseline characteristics were well balanced between the two arms. Median PFS was 2.8 months (mo) (95% CI: 1.6–2.9) for PIM vs. 1.4 mo (95% CI: 0.9–1.8) for PL. The hazard ratio (HR) for PFS was 0.51 (95% CI: 0.30–0.87) ( p = 0.006, stratified log-rank test). Median OS was 13.8 mo (95% CI: 9.2–not reached) for PIM vs. 9.6 mo (95% CI: 5.5–not reached) for PL (HR for OS 0.63; p = 0.081), with 60.7 % of PL pts crossed over to PIM; secondary PFS was 2.7 mo (95% CI: 0.7–4.1). The RPSFT-adjusted median OS of PL was 7.6 mo (adjusted HR for OS 0.42; p = 0.007). Furthermore, the results of PGx analysis suggested that PIM was also effective in pts with secondary KIT mutation detected from blood samples. The most common ( > 5%) grade 3 or higher adverse events (AEs) in PIM/PL were diarrhea (13.8%/0%), anemia (6.9%/10.7%), decreased appetite (6.9%/0%), and tumor hemorrhage (5.2%/0%). AEs leading to PIM/PL study discontinuation were observed in 4/2 pts (6.9%/7.1%), respectively. Conclusions: This randomized trial demonstrated that PIM significantly improved PFS with OS prolongation in pts with advanced GIST refractory to IM, SU, and REG, as a HSP90 inhibitor for the first time. PIM was tolerated and AEs were manageable. With a mechanism of action different from that of standard therapies, PIM has the potential to be a new standard treatment in GIST.

Abstract
2509 Background: TGF-β plays a key role in regulating the tumor microenvironment. Emerging evidence suggests TGF-β is a key activator of cancer-associated fibroblasts, leading to fibrotic network development and immune exclusion. Preclinical data in murine models showed that TGF-β blockade alleviates intratumoral fibrosis, augmenting the efficacy of PD-1 immunotherapy. NIS793 is a human IgG2 mAb that binds to TGF-β. This study investigates NIS793 + spartalizumab in pts with advanced solid tumors. Methods: Pts initially received NIS793 (0.3–1 mg/kg Q3W) monotherapy; following evaluation of two dose levels, dose escalation continued with NIS793 + spartalizumab (NIS793 0.3–30 mg/kg Q3W + spartalizumab 300 mg Q3W; or NIS793 20–30 mg/kg Q2W + spartalizumab 400 mg Q4W) in pts with/without prior anti-PD-(L)1 therapy. In dose expansion, pts with non-small cell lung cancer (NSCLC) resistant to prior anti-PD-(L)1 or pts with microsatellite stable colorectal cancer (MSS-CRC) were treated at the recommended dose for expansion (RDE). Paired tumor biopsies were required from all pts. The primary objectives were to characterize safety and tolerability of the combination and determine the RDE. Results: By December 1, 2020, 60 pts were treated in the dose-escalation phase, mainly with NIS793 + spartalizumab (n = 49), and 60 pts were treated in dose expansion (MSS-CRC: n = 40; NSCLC: n = 20). Two pts were still receiving treatment. No dose-limiting toxicities were observed, and the RDE was established as 30 mg/kg (2100 mg) NIS793 + 300 mg spartalizumab Q3W. Overall 50% pts experienced ≥1 treatment-related AE (TRAE). The most common were rash (n = 15/120), pruritus (n = 10/120), fatigue (n = 9/120), and nausea (n = 8/120). Grade 3/4 TRAEs occurred in 11% pts, with rash (3%) being the most common. Treatment-related serious AEs were reported in 8 pts; 6 were grade 3/4 in severity. No deaths occurred due to AEs; 3 (2.5%) pts discontinued due to AEs. PK for NIS793 was linearly dose proportional with no obvious correlation between exposure and response. Two pts achieved a partial response (PR; one confirmed in clear cell renal cell carcinoma and one unconfirmed in NSCLC) during dose escalation of the combination. Two confirmed PRs were achieved in the MSS-CRC dose-expansion group. Biomarker data showed evidence of target engagement through increased TGF-β/NIS793 complexes and depleted active TGF-β in peripheral blood. Gene expression and protein analyses in tumor biopsies displayed decreased TGF-β target genes, decreased TGF-β signatures and increased immune signatures suggesting modulation of the TGF-β pathway and preliminary evidence of biological activity. Conclusions: Data showing target engagement and TGF-β pathway inhibition supported the proof of mechanism of NIS793. The RDE of the combination was established and well tolerated in pts with advanced solid tumors. Clinical trial information: NCT02947165.

Abstract
PURPOSE T-cell immunoglobulin and mucin-domain-containing molecule-3 (TIM-3) blunts anticancer immunity and mediates resistance to programmed death 1 (PD-1) and PD ligand 1 (PD-L1) inhibitors. We assessed a novel, first-in-class, TIM-3 mAb, LY3321367, alone or in combination with the anti-PD-L1 antibody, LY300054 in patients with advanced solid tumor. PATIENTS AND METHODS This open-label, multicenter, phase Ia/b study aimed to define the safety/tolerability and recommended phase II dose (RP2D) of LY3321367 with or without LY300054. Secondary objectives included pharmacokinetics/pharmacodynamics, immunogenicity, and efficacy. Biomarkers were assessed in exploratory analysis. RESULTS No dose-limiting toxicities were observed in the monotherapy (N = 30) or combination (N = 28) dose escalation. LY3321367 treatment-related adverse events (≥2 patients) included pruritus, rash, fatigue, anorexia, and infusion-related reactions. Dose-proportional increase in LY3321367 concentrations was not affected by either LY300054 or antidrug antibodies (observed in 50%-70% of patients). Pharmacokinetic/pharmacodynamic modeling indicated 100% target engagement at doses ≥600 mg. LY3321367 RP2D was 1,200 mg biweekly for four doses followed by 600 mg every 2 weeks thereafter. In the non-small cell lung cancer monotherapy expansion cohort, outcomes varied by prior anti-PD-1 therapy response status: anti-PD-1/L1 refractory patients [N = 23, objective response rate (ORR) 0%, disease control rate (DCR) 35%, progression-free survival (PFS) 1.9 months] versus anti-PD-1/L1 responders (N = 14, ORR 7%, DCR 50%, PFS 7.3 months). In combination expansion cohorts (N = 91), ORR and DCR were 4% and 42%; CD8 infiltration in paired biopsies increased in approximately half these patients. CONCLUSIONS LY3321367 exhibited acceptable safety profile with favorable pharmacokinetics/pharmacodynamics but only modest antitumor activity. The therapeutic relevance of TIM-3 blockade requires further investigation.

Abstract
Antibody-mediated transient depletion of CD4+ cells enhances the expansion of tumor-reactive CD8+ T cells and exhibits robust antitumor effects in preclinical and clinical studies. To investigate the clonal T-cell responses following transient CD4+ cell depletion in patients with cancer, we conducted a temporal analysis of the T-cell receptor (TCR) repertoire in the first-in-human clinical trial of IT1208, a defucosylated humanized monoclonal anti-CD4. Transient depletion of CD4+ cells promoted replacement of T-cell clones among CD4+ and CD8+ T cells in the blood. This replacement of the TCR repertoire was associated with the extent of CD4+ T-cell depletion and an increase in CD8+ T-cell count in the blood. Next, we focused on T-cell clones overlapping between the blood and tumor in order to track tumor-associated T-cell clones in the blood. The total frequency of blood-tumor overlapping clones tended to increase in patients receiving a depleting dose of anti-CD4, which was accompanied by the replacement of overlapping clones. The greater expansion of CD8+ overlapping clones was commonly observed in the patients who achieved tumor shrinkage. These results suggested that the clonal replacement of the TCR repertoire induced by transient CD4+ cell depletion was accompanied by the expansion of tumor-reactive T-cell clones that mediated antitumor responses. Our findings propose beneficial remodeling of the TCR repertoire following transient CD4+ cell depletion and provide novel insight into the antitumor effects of monoclonal anti-CD4 treatment in patients with cancer.See related Spotlight on p. 601.

Abstract
Currently, the only approved treatments for gastrointestinal stromal tumor (GIST) are tyrosine kinase inhibitors (TKI), which eventually lead to the development of secondary resistance mutations in KIT or PDGFRA and disease progression. Herein, we identified G protein-coupled receptor 20 (GPR20) as a novel non-tyrosine kinase target in GIST, developed new GPR20 IHC, and assessed GPR20 expression in cell lines, patient-derived xenografts, and clinical samples from two institutes (United States and Japan). We studied GPR20 expression stratified by treatment line, KIT expression, GIST molecular subtype, and primary tumor location. We produced DS-6157a, an anti-GPR20 antibody-drug conjugate with a novel tetrapeptide-based linker and DNA topoisomerase I inhibitor exatecan derivative (DXd). DS-6157a exhibited GPR20 expression-dependent antitumor activity in GIST xenograft models including a GIST model resistant to imatinib, sunitinib, and regorafenib. Preclinical pharmacokinetics and safety profile of DS-6157a support its clinical development as a potential novel GIST therapy in patients who are refractory or have resistance or intolerance to approved TKIs. SIGNIFICANCE: GPR20 is selectively expressed in GIST across all treatment lines, regardless of KIT/PDGFRA genotypes. We generated DS-6157a, a DXd-based antibody-drug conjugate that exhibited antitumor activity in GIST models by a different mode of action than currently approved TKIs, showing favorable pharmacokinetics and safety profiles.This article is highlighted in the In This Issue feature, p. 1307.

Background
Type 2 diabetes mellitus (T2DM) is a well-known risk factor for heart failure (HF), even in patients without a structural heart disease or a symptom of HF. Diabetes-related cardiomyopathy is presented as an left ventricular (LV) diastolic dysfunction, which, like cardiovascular disease, is a contributor of the development of HF in both patients with reduced ejection fraction (HFrEF) and with preserved ejection fraction (HFpEF). Furthermore, comorbid factors other than T2DM also have been identified as high risk factors for of progression to HF. Dapagliflozin is a sodium glucose cotransporter type 2 (SGLT2) inhibitor, and represents a new class of anti-hyperglycemic agents for T2DM. A result from a recent large clinical trial showed that dapagliflozin reduced risk of worsening HF or death from cardiovascular causes for patients with HFrEF compared to those who received a placebo, regardless of the presence or absence of T2DM. However, the effect of SGLT2 inhibitors on LV diastolic function in T2DM patients with HF who had cardiovascular risk factors other than T2DM remains uncertain.
Purpose
Our purpose was to investigate the impact of dapagliflozin on LV diastolic function in T2DM patients with stable HF complicating cardiovascular risk factors.
Methods
We analyzed data from our previous prospective multicenter study, which investigate the effect of dapagliflozin on LV diastolic function of 53 T2DM patients with stable HF at five institutions in Japan. Patients who had been taking at least one antidiabetic drugs other than SGLT2 inhibitor started the administration of dapagliflozin. Cardiovascular risk factors other than T2DM was determined as age, gender, hypertension, dyslipidemia, history of cardiovascular events and overweight.
Results
E/e′ significantly decreased from 9.3 to 8.5 cm/s 6 months after administration of dapagliflozin (p = 0.020) as previously described. Multivariate logistic regression analysis showed that dyslipidemia was the only independent determinant of an improvement of E/e’ among cardiovascular risk factors. Furthermore, relative changes in E/e’ from baseline to 6 months after administration of dapagliflozin seen in HFpEF patients with dyslipidemia were significantly larger than those in HFpEF patients without dyslipidemia (-15.2% vs. 29.6%, p = 0.014), but such a difference was not observed in non-HFpEF patients. In addition, relative changes in high-density lipoprotein cholesterol (HDL-C) from baseline to 6 months after administration of dapagliflozin had significant correlation with those in E/e’ (r=-0.300, p = 0.038). However, such correlations were not observed in low-density lipoprotein cholesterol (LDL-C) and triglyceride (r = 0.05, p = 0.72 and r = 0.05, p = 0.73). Conclusion: Dapagliflozin was more beneficial effect on LV diastolic function for T2DM patients with stable HF, especially those with complicating dyslipidemia. Our findings may thus offer a new insight into the management of T2DM patients with HF.

Abstract
Despite curative-intent treatment, most patients with locally advanced esophageal cancer will experience disease recurrence or locoregional progression, highlighting the need for new therapies. Current guidelines recommend definitive chemoradiotherapy in patients ineligible for surgical resection, but survival outcomes are poor. Pembrolizumab is well tolerated and provides promising antitumor activity in patients with previously treated, advanced, unresectable esophageal/esophagogastric junction cancer. Combining pembrolizumab with chemoradiotherapy may further improve outcomes in the first-line setting. Here, we describe the design and rationale for the double-blind, Phase III, placebo-controlled, randomized KEYNOTE-975 trial investigating pembrolizumab in combination with definitive chemoradiotherapy as first-line treatment in patients with locally advanced, unresectable esophageal/gastroesophageal junction cancer. Overall survival and event-free survival are the dual primary end points. Clinical trial registration: NCT04210115 (ClinicalTrials.gov)

Abstract
Spartalizumab is a humanized IgG4/κ mAb directed against human programmed cell death-1 (PD-1). In this phase I study, we investigated safety, pharmacokinetics, preliminary antitumor activity, and toxicity of spartalizumab in patients with advanced malignancies. Patients (n = 18) with a range of tumor types received spartalizumab i.v. at doses of 1, 3, and 10 mg/kg every 2 weeks until disease progression, unacceptable toxicity, or discontinuation at the discretion of the investigator or patient. Most patients (61%) had received five or more prior lines of therapy. No dose-limiting toxicities were reported and, hence, the maximum tolerated dose was 10 mg/kg or more. Pharmacokinetics in Japanese patients aligned with those reported in a global dose-escalation study. The safety profile was consistent with other approved anti-PD-1 mAbs; the most common drug-related adverse events were maculopapular rash (22%), followed by malaise and increased blood alkaline phosphatase (11% each). Partial responses were reported in two patients (11%), one with transitional cell carcinoma and the other with hepatocellular carcinoma. In conclusion, this study confirmed the safety of spartalizumab given at a dose of up to 10 mg/kg every 2 weeks in Japanese patients with cancers.

Abstract
476 Background: Nutritional status is closely linked to cancer mortality, and BWL has been shown to be prognostic for survival in curative, first-, and second-line settings in mGC/GEJC. In the phase III TAGS trial, trifluridine/tipiracil (FTD/TPI) showed clinical benefit versus placebo (PBO) and manageable safety in pts with mGC/GEJC who had received ≥2 prior chemotherapy regimens. The association of early BWL with survival outcomes in TAGS was examined in retrospective analyses. Methods: The TAGS intent-to-treat (ITT) population was categorized into pts who experienced <3% or ≥3% BWL from the start of treatment until day 1 of cycle 2 (each cycle: 28 days). Overall survival (OS), and progression-free survival (PFS) were compared between subgroups within each treatment arm due to significant imbalances of early BWL between treatment arms. The effect of early BWL on OS was assessed by a univariate Cox proportional hazards (PH) model as well as a multivariate Cox PH model that adjusted for baseline prognostic factors identified in the original ITT analysis. Results: Body weight data were available for 451 of 507 (89%) pts in the study (n=304, FTD/TPI; n=147, PBO). In the FTD/TPI and PBO arms, respectively, 74% (224/304 pts) and 65% (95/147) experienced <3% BWL, whereas 26% (80/304) and 35% (52/147) experienced ≥3% BWL at the end of cycle 1. Pts with <3% BWL had longer OS than those with ≥3% BWL in both FTD/TPI (median [m] OS: 6.5 vs 4.9 months [mo]; hazard ratio [HR], 0.75; 95% CI, 0.55–1.02) and PBO arms (mOS: 6.0 vs 2.5 mo; HR, 0.32; 95% CI, 0.21–0.49). The PFS HR for pts with <3% BWL vs ≥3% BWL was 0.95 (95% CI, 0.71–1.25; mPFS, 2.1 vs 1.9 mo) in the FTD/TPI group and 0.49 (95% CI, 0.34–0.72; mPFS, 1.9 vs 1.7 mo) in the PBO group. In the pooled ITT population, the unadjusted HR for the <3% vs ≥3% BWL group calculated using a univariate Cox model was 0.58 (95% CI, 0.46–0.73), indicating a strong prognostic effect of early BWL. Results of multivariate analyses were consistent with univariate analyses and suggested that early BWL was both a prognostic ( P<0.0001) and predictive (interaction P=0.0003) factor for OS in pts with mGC/GEJC. Grade ≥3 adverse events (AEs) of any cause were reported in 77% and 82% of FTD/TPI-treated pts in the <3% and ≥3% BWL subgroups, respectively, and in 45% and 67% of placebo-treated pts in the <3% and ≥3% BWL subgroups. Conclusions: To our knowledge, this is the first analysis to show that BWL is negatively associated with survival in pts with mGC/GEJC receiving third- or later-line treatment. In TAGS, early BWL (≥3% BWL at the end of cycle 1) was a strong negative prognostic factor for OS regardless of FTD/TPI or PBO treatment. Grade ≥3 AE frequencies were similar in FTD/TPI-treated pts with <3% or ≥3% BWL. The relationship of BWL to other prognostic factors will be explored further. Clinical trial information: NCT02500043.

Abstract
168 Background: In the randomized, international, double-blind, placebo-controlled KEYNOTE-590 (NCT03189719) study, pembrolizumab (pembro) + chemotherapy (chemo) provided statistically significant and clinically meaningful improvement in OS, PFS, and ORR vs placebo + chemo as first-line therapy for patients (pts) with locally advanced/unresectable or metastatic adenocarcinoma or esophageal squamous cell carcinoma (ESCC) or Siewert type 1 esophagogastric junction adenocarcinoma (EGJ). Here we report HRQoL outcomes in KEYNOTE-590. Methods: 749 pts were randomized 1:1 to pembro 200 mg or placebo Q3W for up to 2y + chemo (cisplatin 80 mg/m2 Q3W [d1; 6 doses] + 5-FU 800 mg/m2 on d1-5 Q3W). EORTC QLQ-C30, EORTC QLQ-OES18, and EQ-5D-5L questionnaires were administered at baseline, every 3 weeks (Q3W) up to week 24, and then Q9W up to 1 year or end of treatment, and at the 30-d safety follow-up visit. HRQoL was assessed in all treated patients who completed ≥1 HRQoL assessment (N = 711: 356 for pembro + chemo; 355 for chemo). Change from baseline to week 18 in EORTC-QLQ-C30 global health status (GHS)/QoL and physical functioning, and in QLQ-OES18 scores were prespecified secondary endpoints. Change from baseline to week 18 in EQ-5D scores was an exploratory endpoint. Time to deterioration (TTD) was evaluated for all endpoints. Least square mean (LSM) change from baseline (95% CI) was compared using a constrained longitudinal data analysis model. TTD was compared using a stratified log rank test and Cox proportional hazards model. P-values are nominal and two-sided. Results: QLQ-C30, QLQ-OES18 and EQ-5D-5L compliance was ≥90% in both arms at baseline and at week 18. There was no significant difference in least squares mean (LSM) change from baseline to week 18 in GHS/QoL status between arms (LSM difference [95% CI] -0.10 [-3.40-3.20]; P = 0.9530). Median TTD in GHS/QoL was similar between arms (HR, 0.86 [95% CI, 0.66-1.13]; P = 0.2864). Outcomes were similar in ESCC PD-L1 CPS ≥10, ESCC, and PD-L1 CPS ≥10 patient populations. LSM change from baseline to week 18 for QLQ-OES18 pain subscale was better for pembro + chemo (-4.78) vs chemo (-1.85 ) (-2.94, -5.86 to -0.02; P = 0.0487). There was no significant difference in LSM change from baseline to week 18 between arms for reflux (-1.19; -4.49-2.10; P = 0.4781) or dysphagia (-2.35; -7.78-3.07; P = 0.3945). VAS LSM change from baseline to week 18 was similar between arms (1.20, -1.61-4.01; P = 0.4016). Conclusions: HRQoL was stable and similar over 18 weeks in the pembro + chemo and chemo arms. Together with superior OS, PFS, and ORR and a manageable safety profile with pembro + chemo, these results support the clinically meaningful benefit of pembro + chemo in patients with advanced esophageal cancer including EGJ adenocarcinoma. Clinical trial information: NCT03189719.

Abstract
229 Background: Metastatic gastroesophageal cancer (GC/GEJC) is an aggressive disease with poor prognosis and a median overall survival (mOS) of around 1 year. While new treatments have emerged, the need for better understanding of the biology and patient profiling is essential given the heterogeneity of the disease. Previously, the TAGS study showed an improved OS with trifluridine/tipiracil (FTD/TPI) vs placebo in heavily pretreated metastatic GC/GEJC patients with a 31% risk reduction in death. This exploratory subgroup analysis of TAGS aims to assess the efficacy, safety, and quality of life (QoL) results observed in patients who received FTD/TPI or placebo in third line (3L) and those who received FTD/TPI beyond the third line (4L+). This analysis will help provide physicians a clearer view of what is expected in the third-line setting in terms of outcomes and to confirm the efficacy of FTD/TPI in later lines. Methods: Patients were divided into two groups: (i) patients who had received FTD/TPI or placebo after two lines of previous systemic therapy (3L) (n = 126 vs 64); and (ii) patients who had received FTD/TPI or placebo (n = 211 vs 106) after three or more lines of previous systemic therapy (4L+). Patient demographics/baseline characteristics, efficacy (OS, progression-free survival [PFS], and time to ECOG deterioration to 2 or more), safety, and QoL were assessed accordingly in these two groups. Results: Patient baseline characteristics in both groups were well balanced between FTD/TPI and placebo. The mOS for FTD/TPI vs placebo in 3L was 6.8 vs 3.2 months (HR, 0.67; 95% CI, 0.47-0.97; P= 0.0318); whereas, in 4L+, it was 5.2 vs 3.7 months (HR, 0.72; 95% CI, 0.55-0.95; P= 0.0192). The mPFS for FTD/TPI vs placebo in 3L was 3.1 vs 1.9 months (HR, 0.54; 95% CI, 0.38-0.77; P= 0.0004); whereas, in 4L+, it was 1.9 vs 1.8 months (HR, 0.57; 95% CI, 0.44-0.74; P< 0.0001). Time to deterioration of ECOG to 2 or more for FTD/TPI vs placebo in 3L was 4.8 vs 2.0 months (HR, 0.60; 95% CI, 0.42-0.86; P= 0.0049); whereas, in 4L+, it was 4.0 vs 2.5 months (HR, 0.75; 95% CI, 0.57-0.98; P= 0.0329). No relevant clinical differences were found in the impact on QoL in the overall study population. The safety profile of FTD/TPI remained consistent through all subgroup analyses. Conclusions: This analysis confirms the efficacy and safety of using FTD/TPI vs placebo in GC/GEJC patients in third and later lines with a survival benefit that seems to be slightly superior in 3L. Results of QoL in both 3L and 4L+ were consistent with previously published subgroup analyses and with the overall TAGS study population. When FTD/TPI is taken in 3L as recommended in the international guidelines, physicians can expect to provide their patients with a mOS of 6.8 and mPFS of 3.1 months. Clinical trial information: NCT02500043.

Abstract
TPS480 Background: The pan- FGFR tyrosine kinase inhibitor erdafitinib is approved by the US Food and Drug Administration for adults with locally advanced or metastatic urothelial carcinoma and susceptible FGFR3/2 genetic alterations who have progressed during or after ≥ 1 line of prior platinum-containing chemotherapy. FGFR gene alterations are potential oncogenic drivers that have been reported in many solid tumors in adult and pediatric pts. Because of limited response to standard of care options in pts failing systemic therapy, there is strong rationale to assess the safety and efficacy of erdafitinib in adolescent and adult pts with advanced solid tumors and FGFR alterations. Methods: This phase 2, open-label study (RAGNAR/42756493CAN2002; NCT04083976) will include pts aged ≥ 12 years with histologically confirmed unresectable, locally advanced, or metastatic solid tumors (except urothelial tumors) harboring predefined FGFR mutations or fusions. Eligibility screening includes molecular screening for FGFR alterations by central or local next-generation sequencing assays, and other clinical criteria. Pts will enroll into either a broad panel cohort (BPC) of target FGFR alterations or an exploratory cohort (EC) for FGFR alterations that do not meet criteria for BPC. Approximately 280 pts (BPC, n = 240; EC, n = 40) will be enrolled. The primary efficacy end point is overall response rate (ORR) as assessed by the independent review committee. Secondary end points include investigator-assessed ORR, duration of response, disease control rate, progression-free survival, overall survival, safety, pharmacokinetics, and health-related quality of life. Safety assessments include adverse events, vital signs, electrocardiograms, physical examinations, laboratory tests, performance status assessment, growth assessments in adolescents, and ophthalmologic examination. As of December 2019, pts are being enrolled at ~158 sites in 15 countries. Results of this study will provide efficacy and safety data for erdafitinib across multiple solid tumors with FGFR alterations and evaluate the potential benefit of targeting the underlying altered biology of FGFR irrespective of tumor histology in adult and adolescent pts. Clinical trial information: NCT04083976.

Abstract
BACKGROUND Patients with advanced gastroesophageal junction cancer (GEJC) have poor survival outcomes, and GEJC-specific data from trials evaluating agents in gastric cancers (GCs) as a whole are lacking. Trifluridine/tipiracil (FTD/TPI) was approved for previously treated metastatic GC or GEJC (mGC/mGEJC) based on results of the phase 3 TAGS trial. Subgroup analyses by primary tumor type (GC or GEJC) in TAGS are reported here. METHODS Pa tients with mGC/mGEJC treated with ≥ 2 prior chemotherapy regimens were randomized (2:1) to receive FTD/TPI or placebo, plus best supportive care. A pre-planned sub-analysis was performed to evaluate efficacy and safety outcomes by primary tumor type (GEJC or GC). RESULTS Of 507 randomized patients, 145 (29%) had GEJC and 360 (71%) had GC as the primary disease site. Baseline characteristics were generally similar between the GEJC and GC subgroups, except that more patients in the GEJC subgroup had received ≥ 3 prior regimens (72 vs. 59% in the GC subgroup). Survival benefit with FTD/TPI was observed in both subgroups. The overall survival hazard ratio for FTD/TPI vs placebo was 0.75 (95% CI 0.50-1.11) and 0.67 (95% CI 0.52-0.87) in the GEJC and GC subgroups, respectively. Grade ≥ 3 adverse events of any cause were reported in 75 (77%) and 192 (81%) FTD/TPI-treated patients in the GEJC and GC subgroups, respectively. No new safety concerns were noted with FTD/TPI. CONCLUSION As in patients with GC, FTD/TPI showed an efficacy benefit in patients with GEJC in the TAGS trial, along with demonstrating a manageable safety profile.

Abstract
OBJECTIVES Driving a car is essential for older adults to support their activities of daily living and maintain their quality of life. However, physical function - which often declines with age - is a key factor to determine whether older adults can continue driving safely. As such, we sought to examine the association between sarcopenia and driving cessation in older adults. DESIGN A prospective study. SETTING A community setting. PARTICIPANTS We conducted a study including 2,874 older adult participants from the community (mean age: 71.0 ± 4.7 years [range: 65-93 years], women: 36.3%). MEASUREMENTS We assessed whether they were still driving at baseline examination as well as their degree of sarcopenia. Sarcopenia was assessed according to the clinical definition provided by the EWGSOP2 by measuring muscle mass, muscle strength, and physical performance represented by gait speed. Driving cessation was determined based on driving status at the initial visit and at a follow-up examination approximately 15 months later. RESULTS At the baseline assessment, there were 62 participants (2.2%) with confirmed sarcopenia and 23 participants (0.8%) with severe sarcopenia. Participants were classified into either the ongoing driving (n = 2816) or driving cessation (n = 58) group. Low muscle strength and low muscle mass were associated with driving cessation (low muscle strength: odds ratio [OR] 2.09, 95% confidence interval [CI] 1.13-3.87; low muscle mass: OR 2.00, 95% CI 1.04-3.85). Slow gait was not associated with driving cessation (OR 1.35, 95% CI 0.68-2.69). Significantly, sarcopenia was associated with driving cessation (confirmed sarcopenia: OR 4.48, 95% CI 1.63-12.29; severe sarcopenia: OR 4.46, 95% CI 1.21-16.41). CONCLUSIONS Sarcopenia is associated with an increased likelihood of driving cessation in community-dwelling older adults. Evaluation of physical function related to sarcopenia would be useful for judgment of the ability to drive safely among older adults.

Abstract
Budigalimab is a humanized, recombinant, Fc mutated IgG1 monoclonal antibody targeting programmed cell death 1 (PD‐1) receptor, currently in phase I clinical trials. The safety, efficacy, pharmacokinetics (PKs), pharmacodynamics (PDs), and budigalimab dose selection from monotherapy dose escalation and multihistology expansion cohorts were evaluated in patients with previously treated advanced solid tumors who received budigalimab at 1, 3, or 10 mg/kg intravenously every 2 weeks (Q2W) in dose escalation, including Japanese patients that received 3 and 10 mg/kg Q2W. PK modeling and PK/PD assessments informed the dosing regimen in expansion phase using data from body‐weight‐based dosing in the escalation phase, based on which patients in the multihistology expansion cohort received flat doses of 250 mg Q2W or 500 mg every four weeks (Q4W). Immune‐related adverse events (AEs) were reported in 11 of 59 patients (18.6%), of which 1 of 59 (1.7%) was considered grade ≥ 3 and the safety profile of budigalimab was consistent with other PD‐1 targeting agents. No treatment‐related grade 5 AEs were reported. Four responses per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 were reported in the dose escalation cohort and none in the multihistology expansion cohort. PK of budigalimab was approximately dose proportional and sustained > 99% peripheral PD‐1 receptor saturation was observed by 2 hours postdosing, across doses. PK/PD and safety profiles were comparable between Japanese and Western patients, and exposure‐safety analyses did not indicate any trends. Observed PK and PD‐1 receptor saturation were consistent with model predictions for flat doses and less frequent regimens, validating the early application of PK modeling and PK/PD assessments to inform the recommended dose and regimen, following dose escalation.

Abstract
PURPOSE Patients with advanced esophageal cancer have a poor prognosis and limited treatment options after first-line chemotherapy. PATIENTS AND METHODS In this open-label, phase III study, we randomly assigned (1:1) 628 patients with advanced/metastatic squamous cell carcinoma or adenocarcinoma of the esophagus, that progressed after one prior therapy, to pembrolizumab 200 mg every 3 weeks for up to 2 years or chemotherapy (investigator's choice of paclitaxel, docetaxel, or irinotecan). Primary end points were overall survival (OS) in patients with programmed death ligand-1 (PD-L1) combined positive score (CPS) ≥ 10, in patients with squamous cell carcinoma, and in all patients (one-sided α 0.9%, 0.8%, and 0.8%, respectively). RESULTS At final analysis, conducted 16 months after the last patient was randomly assigned, OS was prolonged with pembrolizumab versus chemotherapy for patients with CPS ≥ 10 (median, 9.3 v 6.7 months; hazard ratio [HR], 0.69 [95% CI, 0.52 to 0.93]; P = .0074). Estimated 12-month OS rate was 43% (95% CI, 33.5% to 52.1%) with pembrolizumab versus 20% (95% CI, 13.5% to 28.3%) with chemotherapy. Median OS was 8.2 months versus 7.1 months (HR, 0.78 [95% CI, 0.63 to 0.96]; P = .0095) in patients with squamous cell carcinoma and 7.1 months versus 7.1 months (HR, 0.89 [95% CI, 0.75 to 1.05]; P = .0560) in all patients. Grade 3-5 treatment-related adverse events occurred in 18.2% of patients with pembrolizumab versus 40.9% in those who underwent chemotherapy. CONCLUSION Pembrolizumab prolonged OS versus chemotherapy as second-line therapy for advanced esophageal cancer in patients with PD-L1 CPS ≥ 10, with fewer treatment-related adverse events.

Abstract
Non‐Hodgkin lymphoma (NHL) treated with chemoimmunotherapy has limited efficacy in some patients, resulting in relapsed or refractory disease. Avadomide (CC‐122) is a novel cereblon‐binding agent that exhibits antilymphoma and immune‐modulation activities with a biological profile distinct from similar agents, such as lenalidomide. This phase I multicenter study evaluated avadomide in Japanese patients with advanced solid tumors or NHL. Fourteen patients with NHL and one with a solid tumor (esophageal carcinoma), were enrolled in four dose‐escalation cohorts using a 3 + 3 design. Primary endpoints included safety, dose‐limiting toxicities (DLT), maximum‐tolerated dose and/or recommended phase II dose (RP2D), and pharmacokinetics. Secondary endpoints included overall response rate (ORR) and duration of response. One patient with NHL experienced DLT, which included face edema, pharyngeal edema, and tumor flare (all grade 1) that led to a dose reduction. Eleven patients had grade ≥3 treatment‐emergent adverse events, most frequently decreased neutrophil count (33%) and decreased lymphocyte count (20%). The ORR in patients with NHL (n = 13) was 54%, including four complete and three partial responses. The best response for the solid tumor patient was progressive disease. Avadomide dose intensity was consistent across cohorts, and the 3‐mg dose given five consecutive days/week was established as the RP2D. This phase I study identified a tolerable dose of avadomide, with an acceptable toxicity profile and clinically meaningful efficacy in Japanese patients with previously treated NHL.

Abstract
Abstract
Introduction
Lipoprotein (a) [Lp (a)] is a plasma lipoprotein which exhibits atherogenic properties. Lp(a) ≥50 mg/dl has been recently shown to associate with a risk of atherosclerotic cardiovascular diseases (ASCVD) in patients with heterozygous familial hypercholesterolemia (HeFH). While current guideline recommends lowering LDL-C as a first-line therapeutic approach in HeFH subjects, it remains to be fully determined whether an elevated level of Lp(a) confers additional ASCVD risks in HeFH patients who achieved a lower LDL-C level.
Purpose
To investigate cardiovascular outcomes in HeFH subjects with a lower LDL-C but an elevated Lp(a) levels.
Methods
182 HeFH patients with on-treatment LDL-C <2.6 mmol/l under lipid-lowering therapies were analyzed. Clinical characteristics and MACE (= a composite of all-cause death, ACS, stroke, PAD and coronary revascularization) were compared in HeFH subjects with Lp(a) ≥ vs. <50 mg/dl.
Results
The averaged LDL-C and Lp (a) levels were 1.9 mmol/l and 26.8 mg/dl, respectively. 19.2% of study subjects exhibited Lp(a)≥50 mg/dl. HeFH patients with Lp(a) ≥50 mg/dl were more likely to be older and have a history of hypertension, but these comparisons did not meet statistical significance. There was no significant difference in on-treatment LDL-C, HDL-C and Triglyceride level (Table). However, during the observational period (median=4.7 years), there was a 2.7-fold (95% CI, 1.41–5.02; p=0.004) greater likelihood of experiencing MACE in subjects with Lp(a) ≥50 mg/dl (picture). Even after adjusting clinical demographics, Lp(a) ≥50 mg/dl remained an independent predictor for the occurrence of MACE (hazard ratio=2.53, 95% CI: 1.29–4.82, p<0.001).
Conclusions
Despite achieving on-treatment LDL-C <2.6 mmol/l, an elevated risk of MACE was observed in HeFH patients with Lp(a) ≥50 mg/dl. Our findings suggest an increased level of Lp(a) as a risk stratification marker and a potential therapeutic target in patients with HeFH.

Abstract
Abstract
Introduction
Heterozygous familial hypercholesterolemia (HeFH) exhibits substantially atherogenic substrate which involves coronary and peripheral arteries. Whether atherosclerosis in HeFH propagates to intracranial arteries causing stroke remains to be determined.
Purpose
To characterize intracranial artery stenosis (IAS) in subjects with HeFH.
Methods
148 HeFH subjects who underwent MRI/MRA imaging to evaluate intracranial arteries were analyzed. IAS was defined as the presence of stenosis with its % diameter stenosis ≥25%. Clinical demographics and cardiovascular events (all-cause death, ACS, stroke and PAD) were compared in those with and without IAS.
Results
IAS was observed in 24.3% (=36/148) of study subjects. It was more frequently located at middle cerebral artery (30.6%=11/36), followed by internal carotid artery (25.0%=9/36). 47.2% of IAS exhibited % diameter stenosis ≥75%. Furthermore, 58.3% of HeFH patients with IAS exhibited concomitance of CAD, PAD or carotid stenosis. They were more likely to be older (Table). While there was no significant difference in LDL-C level, an elevated triglyceride level was observed in those with IAS (Table). Of note, during the observational period (median=14.1 years), IAS was associated with a greater likelihood of experiencing not only stroke but other cardiovascular events (all-cause death + ACS + PAD) (picture). Multivariate analysis demonstrated triglyceride level ≥1.7mmol/l as an independent predictor of IAS in HeFH patients (HR=5.53, 95% CI: 1.85–16.5, p=0.002).
Conclusions
Around one-fourth of HeFH patients harboured IAS, which was associated with concomitance of atherosclerosis in other vascular beds and the occurrence of stroke and other cardiovascular events. Given the relationship of IAS with hypertriglyceridemia, this lipid feature may be an important contributor to atherosclerotic formation which involves intracranial artery in HeFH patients.

Abstract
Abstract
Background
Type 2 diabetes mellitus (T2DM) has come to be considered an independent predictor of mortality, and also a contributor to the development of heart failure (HF) with reduced ejection fraction (HFrEF) and with preserved ejection fraction (HFpEF). Left ventricular (LV) longitudinal myocardial dysfunction as assessed in terms of lower global longitudinal strain (GLS), has been identified even in T2DM patients with preserved LV ejection fraction (LVEF), and should be considered the first marker of a preclinical form of DM-related cardiac dysfunction, leading to HFpEF. Sodium glucose cotransporter type 2 (SGLT2) inhibitors represent a new class of anti-hyperglycemic agents for T2DM, but the effect of SGLT2 inhibitors on LV longitudinal myocardial function in T2DM patients with HF remains uncertain. To examine this effect, as well as the association of LV longitudinal myocardial function with LV diastolic function after administration of SGLT2 inhibitor in T2DM patients with stable HF, we analyzed data from our previous prospective multicenter study, in which we investigated the effect of SGLT2 inhibitor on LV diastolic functional parameters of T2DM patients with stable HF at five institutions in Japan.
Methods
Our previous trial was a prospective multicenter study of 58 T2DM patients with stable HF at five institutions in Japan. Patients who had been taking at least one antidiabetic drugs other than SGLT2 inhibitors started the administration of 5 mg/day of dapagliflozin. Echocardiography was performed at baseline and 6 months after administration of dapagliflozin. LV diastolic function was defined as the ratio of mitral inflow E to mitral e' annular velocities (E/e'). LV longitudinal myocardial function was assessed as GLS based on the current guidelines.
Results
E/e' significantly decreased from 9.3 to 8.5 cm/s 6 months after administration of dapagliflozin (p=0.020) as previously described, while GLS showed significant improvement from 15.5±3.5% to 16.9±4.1% (p<0.01) 6 months after administration of dapagliflozin. Furthermore, improvement of GLS in HFpEF patients was more significant from 17.0±1.9% to 18.7±2.0% (p<0.001), compared to that in HFrEF patients from 11.3±3.8% to 11.8±4.6% (p=0.13). It was noteworthy that multiple regression analysis showed that the change in GLS after administration of dapagliflozin was the only independent determinant parameter for the change in E/e' after administration of dapagliflozin.
Conclusion
Dapagliflozin was found to be associated with improvement of LV longitudinal myocardial function, which led to further improvement of LV diastolic function of T2DM patients with stable HF. GLS-guided management may thus lead to improved management of T2DM patients with stable HF.

Abstract
PURPOSE Patients with advanced esophageal cancer have a poor prognosis and limited treatment options after first-line chemotherapy. PATIENTS AND METHODS In this open-label, phase III study, we randomly assigned (1:1) 628 patients with advanced/metastatic squamous cell carcinoma or adenocarcinoma of the esophagus, that progressed after one prior therapy, to pembrolizumab 200 mg every 3 weeks for up to 2 years or chemotherapy (investigator's choice of paclitaxel, docetaxel, or irinotecan). Primary end points were overall survival (OS) in patients with programmed death ligand-1 (PD-L1) combined positive score (CPS) ≥ 10, in patients with squamous cell carcinoma, and in all patients (one-sided α 0.9%, 0.8%, and 0.8%, respectively). RESULTS At final analysis, conducted 16 months after the last patient was randomly assigned, OS was prolonged with pembrolizumab versus chemotherapy for patients with CPS ≥ 10 (median, 9.3 v 6.7 months; hazard ratio [HR], 0.69 [95% CI, 0.52 to 0.93]; P = .0074). Estimated 12-month OS rate was 43% (95% CI, 33.5% to 52.1%) with pembrolizumab versus 20% (95% CI, 13.5% to 28.3%) with chemotherapy. Median OS was 8.2 months versus 7.1 months (HR, 0.78 [95% CI, 0.63 to 0.96]; P = .0095) in patients with squamous cell carcinoma and 7.1 months versus 7.1 months (HR, 0.89 [95% CI, 0.75 to 1.05]; P = .0560) in all patients. Grade 3-5 treatment-related adverse events occurred in 18.2% of patients with pembrolizumab versus 40.9% in those who underwent chemotherapy. CONCLUSION Pembrolizumab prolonged OS versus chemotherapy as second-line therapy for advanced esophageal cancer in patients with PD-L1 CPS ≥ 10, with fewer treatment-related adverse events.
