Head Neck 2020; 42:2852-2862. [PMID: 32583557 PMCID: PMC7540331 DOI: 10.1002/hed.26331] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2020] [Accepted: 05/27/2020] [Indexed: 12/20/2022] Open
Abstract
Background The present study evaluated the 2‐year survival of the Asian population in the CheckMate 141 trial. Methods The CheckMate 141 trial included patients with recurrent or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN). In the present study, 34 Asian patients (nivolumab group: 23 patients; investigator's choice of therapy [IC] group: 11 patients) were analyzed. Results The median overall survival (OS) was 12.1 and 6.2 months for the nivolumab and IC groups, respectively. The estimated 2‐year OS rates were 22.7% and 0% for the nivolumab and IC groups, respectively. In the nivolumab group, the patients with any treatment‐related adverse events (TRAEs), including skin‐related disorders, showed better OS than the patients without any TRAEs. Conclusions Nivolumab demonstrated prolonged OS benefits in the Asian population with platinum‐refractory R/M SCCHN and a favorable safety profile. TRAEs, including skin‐related disorders, may be favorable prognostic factors for nivolumab efficacy. Clinical trial registration NCT02105636.

Abstract
Type 2 diabetes mellitus (T2DM) is a frequent comorbidity of cancer. Hyperinsulinemia secondary to T2DM promotes cancer progression, whereas antidiabetic agents, such as metformin, have anticancer effects. However, the detailed mechanism for insulin and metformin-regulated cancer cell proliferation remains unclear. This study identified a mechanism by which insulin upregulated the expression of c-Myc, sterol regulatory element-binding protein 1 (SREBP1), and acetyl-coenzyme A (CoA) carboxylase 1 (ACC1), which are important regulators of lipogenesis and cell proliferation. Thymine DNA glycosylase (TDG), a DNA demethylase, was transactivated by c-Myc upon insulin treatment, thereby decreasing 5-carboxylcytosine (5caC) abundance in the SREBP1 promoter. On the other hand, metformin-activated AMP-activated protein kinase (AMPK) increased DNA methyltransferase 3A (DNMT3A) activity to increase 5-methylcytosine (5mC) abundance in the TDG promoter. This resulted in decreased TDG expression and enhanced 5caC abundance in the SREBP1 promoter. These findings demonstrate that c-Myc activates, whereas AMPK inhibits, TDG-mediated DNA demethylation of the SREBP1 promoter in insulin-promoted and metformin-suppressed cancer progression, respectively. This study indicates that TDG is an epigenetic-based therapeutic target for cancers associated with T2DM.

[PMID: 32456644 PMCID: PMC7251895 DOI: 10.1186/s12929-020-00664-9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2019] [Accepted: 05/22/2020] [Indexed: 02/07/2023] Open
Abstract
Background Due to differences in genetic background, it is unclear whether the genetic loci identified by the previous genome-wide association studies (GWAS) of pancreatic cancer also play significant roles in the development of pancreatic cancer among the Taiwanese population. Methods This study aimed to validate the 25 pancreatic cancer GWAS-identified single nucleotide polymorphisms (SNPs) in a case-control study (278 cases and 658 controls) of pancreatic cancer conducted in Taiwan. Statistical analyses were conducted to determine the associations between the GWAS-identified SNPs and pancreatic cancer risk. Gene-environment interaction analysis was conducted to evaluate the interactions between SNPs and environmental factors on pancreatic cancer risk. Results Among the 25 GWAS-identified SNPs, 7 (rs2816938 (~ 11 kb upstream of NR5A2), rs10094872 (~ 28 kb upstream of MYC), rs9581943 (200 bp upstream of PDX1) and 4 chromosome 13q22.1 SNPs: rs4885093, rs9573163, rs9543325, rs9573166) showed a statistically significant association with pancreatic cancer risk in the current study. Additional analyses showed two significant gene-environment interactions (between poor oral hygiene and NR5A2 rs2816938 and between obesity and PDX1 rs9581943) on the risk of pancreatic cancer. Conclusions The current study confirmed the associations between 7 of the 25 GWAS-identified SNPs and pancreatic risk among the Taiwanese population. Furthermore, pancreatic cancer was jointly influenced by lifestyle and medical factors, genetic polymorphisms, and gene-environment interaction. Additional GWAS is needed to determine the genetic polymorphisms that are more relevant to the pancreatic cancer cases occurring in Taiwan.

Abstract
Liposomal 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.

Abstract
BACKGROUND Xentuzumab, an insulin-like growth factor (IGF)-1/IGF-2-neutralising antibody, binds IGF-1 and IGF-2, inhibiting their growth-promoting signalling. Two first-in-human trials assessed the maximum-tolerated/relevant biological dose (MTD/RBD), safety, pharmacokinetics, pharmacodynamics, and activity of xentuzumab in advanced/metastatic solid cancers. METHODS These phase 1, open-label trials comprised dose-finding (part I; 3 + 3 design) and expansion cohorts (part II; selected tumours; RBD [weekly dosing]). Primary endpoints were MTD/RBD. RESULTS Study 1280.1 involved 61 patients (part I: xentuzumab 10-1800 mg weekly, n = 48; part II: 1000 mg weekly, n = 13); study 1280.2, 64 patients (part I: 10-3600 mg three-weekly, n = 33; part II: 1000 mg weekly, n = 31). One dose-limiting toxicity occurred; the MTD was not reached for either schedule. Adverse events were generally grade 1/2, mostly gastrointestinal. Xentuzumab showed dose-proportional pharmacokinetics. Total plasma IGF-1 increased dose dependently, plateauing at ~1000 mg/week; at ≥450 mg/week, IGF bioactivity was almost undetectable. Two partial responses occurred (poorly differentiated nasopharyngeal carcinoma and peripheral primitive neuroectodermal tumour). Integration of biomarker and response data by Bayesian Logistic Regression Modeling (BLRM) confirmed the RBD. CONCLUSIONS Xentuzumab was well tolerated; MTD was not reached. RBD was 1000 mg weekly, confirmed by BLRM. Xentuzumab showed preliminary anti-tumour activity. CLINICAL TRIAL REGISTRATION NCT01403974; NCT01317420.

Abstract
430 Background: Pembro has demonstrated promising antitumor activity in patients (pts) with advanced G/GEJ cancer with PD-L1 CPS ≥1 and CPS ≥10 irrespective of MSI-H status. Here, we examine the antitumor activity of pembro monotherapy vs chemo in pts with MSI-H, advanced G/GEJ cancer in KEYNOTE (KN)-059 (NCT02335411), KN061 (NCT02370498), and KN062 (NCT02494583). Methods: Eligible pts with advanced G/GEJ cancer with ≥2 prior therapies (KN059 cohort 1; 3L+), 1 prior therapy (KN061; 2L), or no prior therapy (KN062; 1L) were enrolled. In KN059 cohort 1, pts received pembro only. In KN061 pts were randomized to pembro or paclitaxel (chemo), and in KN062 to pembro, pembro + cisplatin+5-FU/cape (chemo), or chemo. Pts received pembro 200 mg Q3W for up to 2 y. MSI-H status was determined centrally by PCR. Endpoints included OS, PFS, ORR, and safety. Data cutoff dates were Aug 8, 2018 (KN059), Oct 26, 2017 (KN061), and Mar 26, 2019 (KN062). Results: At data cutoff, 259 pts (n = 7 [3%] MSI-H) had enrolled in KN059 cohort 1 (3L+), 592 (27 [5%] MSI-H]) in KN061 (2L), and 763 (50 [7%] MSI-H] in KN062 (1L). Median follow-up was 5.6 mo, 7.9 mo, and 11.3 mo, respectively. For the overall study populations, median OS was 5.5 mo for pembro (3L+), 6.7 mo vs 8.3 mo for pembro vs chemo (2L), and 10.6 mo vs 11.0 mo for pembro vs chemo (1L). Median PFS was 2.0 mo (3L+), 1.5 vs 4.1 mo (2L), and 2.0 vs 6.4 mo (1L). ORR was 11.6% (3L+), 11.1% vs 12.5% (2L), and 14.8% vs 37.2% (1L), with median DOR of 16.1 mo, 18.0 vs 5.5 mo, and 13.7 vs 6.8 mo. In pts with MSI-H tumors, OS and PFS were prolonged with pembro vs chemo, with higher ORR (Table). Conclusions: As with PD-L1 expressers, MSI-H status is a predictive biomarker for pembro monotherapy in advanced G/GEJ cancer irrespective of line of therapy.

Abstract
549 Background: Intermediate-stage HCC, as defined as Barcelona Clinic Liver Cancer (BCLC) Stage B, is a heterogeneous disease in terms of liver function and tumor load. REACH (NCT01140347) and REACH-2 (NCT02435433) investigated ramucirumab (RAM) in patients (pts) with HCC after prior sorafenib (SOR), with REACH-2 enrolling only pts with baseline AFP ≥400 ng/mL. An exploratory analysis of outcomes by BCLC stage was performed. Methods: All pts had HCC (BCLC stage C or B disease refractory/not amenable to locoregional therapy), Child-Pugh A, ECOG PS 0-1, and prior SOR. Pts were randomized to RAM 8 mg/kg or Placebo (P) Q2W. A pooled meta-analysis of independent pt data (stratified by study) from REACH-2 and REACH (AFP ≥400 mg/mL) was performed. Prognosis of BCLC staging in overall survival (OS) was evaluated by multivariate Cox PH model (adjusted for baseline AFP and treatment (trt) arm); Trt effects in BCLC stage B and C by Cox PH model; median OS/PFS were estimated by Kaplan-Meier method. Objective response rate (ORR) per RECIST v1.1, disease control rate (DCR), and adverse events (AEs) were also reported by BCLC. Liver function was assessed at baseline and prior to each trt with the Albumin-Bilirubin (ALBI) linear predictor. Results: Baseline characteristics were generally balanced between trt arms in each BCLC stage. BCLC staging trended as an independent prognosis factor for OS [B v C; HR = 0.756 (0.546, 1.046)]. A consistent trt benefit for RAM v P was observed across staging (Table). Grade ≥3 AEs were consistent with observations from both individual studies; hypertension was the most frequent grade ≥3 AE. No difference in liver function, as measured by ALBI, was observed between trt arms in either BCLC stage. Conclusions: Acknowledging limitations of sample size, RAM provided a survival benefit irrespective of BCLC stage. RAM was well tolerated and did not alter liver function compared to P. Clinical trial information: NCT01140347, NCT02435433. [Table: see text]

Abstract
Many Aurora-A inhibitors have been developed for cancer therapy; however, the specificity and safety of Aurora-A inhibitors remain uncertain. The Aurora-A mRNA yields nine different 5'-UTR isoforms, which result from mRNA alternative splicing. Interestingly, we found that the exon 2-containing Aurora-A mRNA isoforms are predominantly expressed in cancer cell lines as well as human colorectal cancer tissues, making the Aurora-A mRNA exon 2 a promising treatment target in Aurora-A-overexpressing cancers. In this study, a selective siRNA, siRNA-2, which targets Aurora-A mRNA exon 2, was designed to translationally inhibit the expression of Aurora-A in cancer cells but not normal cells; locked nucleic acid (LNA)-modified siRNA-2 showed improved efficacy in inhibiting Aurora-A mRNA translation and tumor growth. Xenograft animal models combined with noninvasion in vivo imaging system (IVIS) analysis further confirmed the anticancer effect of LNA-siRNA-2 with improved efficiency and safety and reduced side effects. Mice orthotopically injected with colorectal cancer cells, LNA-siRNA-2 treatment not only inhibited the tumor growth but also blocked liver and lung metastasis. The results of our study suggest that LNA-siRNA-2 has the potential to be a novel therapeutic agent for cancer treatment.

Abstract
Background The objectives of this phase II study were to determine the clinical activity of the MET tyrosine kinase inhibitor capmatinib (INC280) in patients with MET-dysregulated advanced hepatocellular carcinoma (HCC) and to assess the safety, pharmacokinetics, and correlation of biomarkers with the response. Methods This phase II, open-label, single-arm study evaluated twice daily (BID) oral capmatinib in a dose-determining stage, utilizing a Bayesian Logistic Regression Model (BLRM) subject to Escalation with Overdose Control criteria, safety, pharmacokinetics, and pharmacodynamic information to determine a recommended dose for expansion (RDE) evaluating efficacy in patients with MET-dysregulated HCC. Results A total of 38 patients received treatment. In the dose-determining stage, patients received capmatinib 300 mg BID capsules (n = 8), and in the expansion, patients received 600 mg BID capsules (n = 28) or 400 mg BID tablets (n = 2) based on the BLRM and other relevant clinical data. No predefined qualifying adverse events (AEs) were observed during the first 28 days of treatment, and the RDE was 600 mg BID capsules (equivalent pharmacokinetics to 400 mg BID tablets). The most common any causality AEs were nausea (42%), vomiting (37%), and diarrhea (34%). In the expansion stage, in a subgroup of 10 patients with MET-high HCC, the overall response rate was 30%, including 1 durable complete response (>600 days) and 2 partial responses [1 durable (>600 days)]. Conclusions Single agent capmatinib at the RDE is tolerable with a manageable safety profile. Antitumor activity was seen in a subset of patients with MET-dysregulated (MET-high) HCC.

Abstract
Outcomes for patients with advanced hepatocellular carcinoma (HCC) remain poor despite recent progress in drug development. Emerging data implicate FGF19 as a potential HCC driver, suggesting its receptor, FGFR4, as a novel therapeutic target. We evaluated fisogatinib (BLU-554), a highly potent and selective oral FGFR4 inhibitor, in a phase I dose-escalation/dose-expansion study in advanced HCC using FGF19 expression measured by IHC as a biomarker for pathway activation. For dose escalation, 25 patients received 140 to 900 mg fisogatinib once daily; the maximum tolerated dose (600 mg once daily) was expanded in 81 patients. Fisogatinib was well tolerated; most adverse events were manageable, grade 1/2 gastrointestinal events, primarily diarrhea, nausea, and vomiting. Across doses, the overall response rate was 17% in FGF19-positive patients [median duration of response: 5.3 months (95% CI, 3.7-not reached)] and 0% in FGF19-negative patients. These results validate FGFR4 as a targetable driver in FGF19-positive advanced HCC. SIGNIFICANCE: Fisogatinib elicited clinical responses in patients with tumor FGF19 overexpression in advanced HCC. These results validate the oncogenic driver role of the FGFR4 pathway in HCC and the use of FGF19 as a biomarker for patient selection.See related commentary by Subbiah and Pal, p. 1646.This article is highlighted in the In This Issue feature, p. 1631.

Abstract
BACKGROUND AND AIMS Immune checkpoint inhibitors (ICIs) exhibit significant clinical activity in patients with advanced hepatocellular carcinoma (HCC). This study explored whether tumor response to ICIs in HCC varies among different organs. METHODS We reviewed the data of patients with advanced HCC who had received ICIs. Patients with measurable diseases were enrolled. Organ-specific response criteria, adapted from RECIST 1.1 and immune-related RECIST, were used to evaluate the objective response to ICIs in tumors located in the liver, lung, lymph node, and other intra-abdominal sites. RESULTS Of the 75 enrolled patients with advanced HCC, 51 and 11 patients had chronic hepatitis B virus and chronic hepatitis C virus infection, respectively. Regarding ICI treatment, 58, 1, and 16 patients had undergone anti-PD-1/anti-PD-L1 monoclonal antibody (mAb) alone, anti-CTLA4 mAb alone, and anti-PD-1 mAb plus anti-CTLA4 mAb, respectively; 20 and 55 patients had received ICIs as first-line or ≥second-line therapy. The overall objective response rate (ORR) was 28.0%. In total, 58, 34, 19, and 18 patients had measurable hepatic tumors and lung, lymph node, and other intra-abdominal metastases, and the corresponding organ-specific ORRs were 22.4, 41.2, 26.3, and 38.9%, respectively. Of the 39 patients who had both hepatic and extrahepatic tumors, 12 had disease control in extrahepatic tumors while progressive disease (PD) in hepatic tumors, whereas only 4 exhibited disease control in hepatic tumors while PD in extrahepatic tumors (p = 0.046, McNemar test). Of the 16 patients with only evaluable tumors in the liver and lungs at baseline, 8 had disease control in the lungs while PD in the liver, and none experienced disease control in the liver while PD in the lungs (p = 0.005). CONCLUSIONS The hepatic tumors of HCC may be less responsive to ICIs than extrahepatic lesions. Lung metastases responded most favorably to ICIs. The mechanisms underlying this differential response to ICIs warrant further investigation.

Abstract
Importance Ramucirumab, a human IgG 1 antibody against vascular endothelial growth factor receptor 2, has been shown to improve progression-free survival and overall survival in patients with advanced gastric cancer in the second-line setting. Objective To compare progression-free survival for S-1 and oxaliplatin plus ramucirumab with that for S-1 and oxaliplatin plus placebo in patients with advanced gastric cancer. Design, Setting, and Participants This phase 2, double-blind randomized clinical trial (RAINSTORM [First-line S-1 Plus Oxaliplatin With or Without Ramucirumab Followed by Paclitaxel Plus Ramucirumab in Patients With Advanced Gastric Cancer]) was conducted from October 12, 2015, to April 11, 2018, at 36 sites in Japan, South Korea, and Taiwan. Participants were chemotherapy-naive patients (n = 189) with metastatic gastric or gastroesophageal adenocarcinoma. Analyses of the full analysis set and safety population were conducted between November 27, 2017, and June 4, 2018. Interventions Patients randomized to the ramucirumab plus S-1 and oxaliplatin arm received S-1, 80 to 120 mg/d twice daily, on days 1 to 14 and oxaliplatin, 100 mg/m2, on day 1 with ramucirumab, 8 mg/kg, on days 1 and 8 in part A (21-day cycle). Patients randomized to the placebo plus S-1 and oxaliplatin arm received the same S-1 and oxaliplatin dosage as well as placebo on days 1 and 8 in part A. Eligible patients received second-line paclitaxel, 80 mg/m2, on days 1, 8, and 15 and ramucirumab, 8 mg/kg, on days 1 and 15 in part B (28-day cycle). Main Outcomes and Measures The primary end point was progression-free survival, analyzed using the stratified log-rank test; the hazard ratio (HR) was estimated using the stratified Cox proportional hazards regression model. Secondary end points included overall survival and adverse events. Results In total, 189 patients were randomized and received treatment: 96 to the ramucirumab plus S-1 and oxaliplatin arm and 93 to the placebo plus S-1 and oxaliplatin arm. Among the 189 patients, 121 (64.0%) were male, and the median (range) age was 62.0 (26-84) years. Median progression-free survival was not prolonged in the ramucirumab plus S-1 and oxaliplatin arm compared with the placebo plus S-1 and oxaliplatin arm (6.34 [80% CI, 5.65-6.93] vs 6.74 [80% CI, 5.75-7.13] months; HR, 1.07; 80% CI, 0.86-1.33; P = .70). Median overall survival was 14.65 (80% CI, 12.39-15.67) months in the ramucirumab plus S-1 and oxaliplatin arm and 14.26 (80% CI, 13.83-17.31) months in the placebo plus S-1 and oxaliplatin arm (HR, 1.11; 80% CI, 0.89-1.40; P = .55). The most commonly reported grade 3 or higher treatment-emergent adverse events in the ramucirumab plus S-1 and oxaliplatin arm in part A were decreased neutrophil count (14 patients [14.6%]), hypertension (10 patients [10.4%]), and anemia (10 patients [10.4%]). Conclusions and Relevance In this randomized clinical trial, the addition of ramucirumab to first-line S-1 and oxaliplatin treatment did not prolong progression-free survival or overall survival compared with S-1 and oxaliplatin alone among East Asian patients with advanced gastric cancer; no new safety signals for ramucirumab were identified. Trial Registration ClinicalTrials.gov identifier: NCT02539225.

Abstract
Abstract
Background: HER2/neu is overexpressed in 15-25% of gastric cancer patients and associated with poor prognosis. Alternative treatments to monoclonal antibodies are needed due to cost and global availability issues of mAbs. Thus a B-cell peptide vaccine (IMU-131) was developed, consisting of 3 fused B-cell epitopes (p467) from the HER2/neu extracellular domain coupled to CRM197 applied with the adjuvant Montanide. The current study evaluated the optimal and safe vaccine dose leading to immunogenicity and clinical responses.
Material & Methods: In an open-label multicenter Phase Ib trial in SE-Asia and Eastern Europe, 14 patients with HER2/neu overexpressing (++/+++) gastric or gastroesophageal junction adenocarcinoma were recruited to receive 3 injections of IMU-131 (days 0, 14, 35) in combination with chemotherapy (CT) every 21 days. Dose escalation with 10 µg, 30 µg and 50 µg was performed in 3 cohorts. Safety, immunogenicity and clinical responses were evaluated.
Results: No SAEs related to administration of IMU-131 were reported. Eleven of 14 patients were evaluable for vaccine-specific immune responses and 10 for tumor growth assessment. Higher p467- and Her-2 specific IgG levels were observed in cohort 2 (30 µg/dose) compared to cohort 1 (10 µg/dose). Two of five patients in cohort 2 showed minimal antibody titers. In contrast, all patients in cohort 3 (50µg/dose) responded to the vaccine with equally high antibody levels. Response rate was an exploratory endpoint and of 10 evaluable patients, 5 patients showed partial response and 4 patients showed stable disease. In cohort 3 the high antibody levels correlated with clinical response, while in cohort 2 only moderate correlations between humoral and clinical responses were observed. In cohort 1 partial response did not correlate with Ab levels, but rather with a high percentage of CD8 T-cells and increased inflammatory cytokine levels (high IFN-γ and TNF-α/IL-10 ratio).
Conclusions: The vaccine was well tolerated and safe with antibody responses at the highest dose (50 µg) showing a strong correlation with clinical responses. Thus, a dose of 50 µg was recommended for further evaluation in Phase II, featuring two arms of either IMU 131 plus CT or CT alone. We propose that this vaccine might be of significant medical benefit and further trials are warranted.

Abstract
Abstract
Background Tislelizumab (BGB-A317), an investigational monoclonal antibody with high affinity and specificity for PD-1, was engineered to minimize binding to FcγR on macrophages in order to abrogate antibody-dependent phagocytosis, a potential mechanism of resistance to anti-PD-1 therapy. Previous reports from early phase studies suggest tislelizumab was generally well tolerated and had antitumor activity in patients (pts) with advanced solid tumors. Clinical effects of tislelizumab LTE (>12 mo) in pts enrolled in the first-in-human study (NCT02407990) are presented here.
Methods Patients with advanced solid tumors received IV tislelizumab 0.5, 2, 5, or 10 mg/kg Q2W, 2 or 5 mg/kg administered Q2W or Q3W, or 200 mg IV Q3W. Antitumor activity was assessed by RECIST v1.1 criteria; PD-L1 expression was retrospectively assessed with the VENTANA PD-L1 (SP263) assay.
Results As of 31 Aug 2018, 63 of the 451 pts received tislelizumab for >12 mo. In these 63 pts, median age was 64 yr and 70% had received ≥1 prior systemic therapy. Tislelizumab LTE was most common in NSCLC (n=9), HCC (n=7), and bladder and ovarian (n=5 each) cancers. Four of the 5 pts who achieved CR during this study had LTE to tislelizumab (Table); all 4 pts were PD-L1+ (≥1% expression on tumor cells). Across the LTE cohort, ORR was 66.7%; PR and SD were observed in both PD-L1+ and PD-L1- tumors. The median time to CR/PR (3.7 mo) and duration of CR/PR (21.1 mo) were longer in pts with LTE than pts who responded but did not remain on treatment for >12 mo (2.1 and 6.3 mo, respectively). Rash was the only treatment-related AE (TRAE) reported in ≥15% of pts. Most TRAEs were of mild or moderate severity; arthritis, diarrhea, fatigue, granuloma, hyperglycemia, and lichenoid keratosis (n=1 each) were the only grade ≥3 TRAEs reported with tislelizumab LTE.
Conclusion Tislelizumab remained well tolerated for >12 mo and elicited durable responses in pts with a variety of tumor types regardless of PD-L1 status.

Hepatitis B virus X protein (HBx) enhances centrosomal P4.1-associated protein (CPAP) expression to promote hepatocarcinogenesis. J Biomed Sci 2019; 26:44. [PMID: 31170980 PMCID: PMC6551916 DOI: 10.1186/s12929-019-0534-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2019] [Accepted: 05/14/2019] [Indexed: 02/06/2023] Open
Abstract
Background Our previous report suggested that centrosomal P4.1-associated protein (CPAP) is required for Hepatitis B virus (HBV) encoded non-structure protein X (HBx)-mediated nuclear factor kappa light chain enhancer of activated B cells (NF-κB) activation. CPAP is overexpressed in HBV-associated hepatocellular carcinoma (HCC); however, the interaction between CPAP and HBx in HBV-HCC remains unclear. Methods The mRNA expression of CPAP and HBx was analyzed by quantitative-PCR (Q-PCR). NF-κB transcriptional activity and CPAP promoter activity were determined using a reporter assay in Huh7 and Hep3B cells. Immunoprecipitation (IP) and in situ proximal ligation assay (PLA) were performed to detect the interaction between CPAP and HBx. Chromatin-IP was used to detect the association of cAMP response element binding protein (CREB) and HBx with the CPAP promoter. Cell proliferation was measured using cell counting kit CCK-8, Bromodeoxyuridine (5-bromo-2′-deoxyuridine, BrdU) incorporation, and clonogenic assays. The tumorigenic effects of CPAP were determined using xenograft animal models. Results HBx can transcriptionally up-regulate CPAP via interacting with CREB. Overexpressed CPAP directly interacted with HBx to promote HBx-mediated cell proliferation and migration; SUMO modification of CPAP was involved in interacting with HBx. Knocked-down expression of CPAP decreased the HBx-mediated tumorigenic effects, including cytokines secretion. Interestingly, overexpressed CPAP maintained the HBx protein stability in an NF-κB-dependent manner; and the expression levels of CPAP and HBx were positively correlated with the activation status of NF-κB in HCC. Increased expression of CPAP and CREB mRNAs existed in the high-risk group with a lower survival rate in HBV-HCC. Conclusion The interaction between CPAP and HBx can provide a microenvironment to facilitate HCC development via enhancing NF-κB activation, inflammatory cytokine production, and cancer malignancies. This study not only sheds light on the role of CPAP in HBV-associated HCC, but also provides CPAP as a potential target for blocking the hyper-activated NF-κB in HCC.

Abstract
4030 Background: Gastric cancer is the 5th most common cancer and the 3rd leading cause of cancer deaths. HER2/neu is overexpressed in 15% - 25% of patients with gastric cancer. Monoclonal antibodies against HER2/neu are effective but alternatives are needed due to cost and global availability. IMU-131 is a B-cell peptide vaccine composed of a fusion of 3 epitopes from the extracellular domain of HER2/neu conjugated to CRM197 with the adjuvant Montanide. Polyclonal antibodies against IMU-131 peptides elicit antitumor activity in vitro and a phase I study demonstrated safety and immunogenicity in Her-2 +/++ breast cancer patients. Methods: IMU-131 was given to patients with HER2/neu overexpressing gastric or gastroesophageal junction (GEJ) adenocarcinoma in an international open-label Phase 1b dose escalation trial performed in 14 Asian and Eastern European sites assessing safety, tolerability, and immunogenicity. Each patient received IMU-131 on Days 0, 14, and 35, accompanied by cisplatin and 5-fluorouracil or capecitabine every 21 days. Results: 14 patients were enrolled with advanced stage IIIb or IV with 10 HER2 overexpressing tumors (7 x HER2+++, 3 x HER2++ FISH positive) and 4 HER2++ expressing tumors. Mean age was 57 yo (range of 21 - 79) with ECOG scores of 0 or 1 in 7 patients each. There were 9 Asian and 5 Caucasian patients with 5 females and 9 males. Dose levels were 0.1, 0.3 and 0.5 mg with 3, 6, and 5 patients receiving those dose levels each. 11 patients received all 3 doses with 3 patients who received only 2 doses due to disease progression and 2 patients received a dose on day 182. Of the 14 patients dosed 11 were evaluable for tumor progression at day 56 and later. Of those patients, the best response was 1 CR, 4 PR,5 SD and 1 PD. In the 0.1 mg dose group the best response was 1 CR and 2 SD, with 2 PR, 2 SD and 1 PD in the 0.3 mg group and 2 PR and 1 SD in the 0.5 mg group. In patients with HER2 overexpression there was 1 CR, 4 PR, 2 SD and 1 PD, and in patients with HER2++ expression there was 3 SD. There were no SAEs related to IMU-131 and 1 patient had a mild injection site reaction. Conclusions: IMU-131 is a promising B-Cell vaccine against HER2. Further work in a controlled phase 2 trial is ongoing. Clinical trial information: NCT02795988.

Abstract
4073 Background: Oral multikinase inhibitors that have shown improvements in overall survival (OS) in HCC are associated with clinically important toxicities that commonly require dose adjustment or discontinuation (D/C) due to intolerance. REACH and REACH-2 studied RAM in patients (pts) with HCC who progressed on or were intolerant to sorafenib (SOR), and REACH-2 only enrolled pts with baseline AFP ≥400 ng/mL. In REACH-2 RAM treatment (trt) improved OS compared to placebo (P), supporting findings in REACH pts with baseline AFP ≥400 ng/mL. An exploratory analysis of outcomes by reason for D/C of SOR was performed. Methods: Pts had advanced HCC, Child-Pugh A, ECOG PS 0-1, and prior SOR. Pts were randomized to RAM 8 mg/kg or P Q2W. A pooled independent pt data analysis (stratified by study) of REACH-2 and REACH pts (AFP ≥400 mg/mL) was performed. Results are reported by reason for SOR D/C (intolerance or disease progression). OS and PFS were evaluated using Kaplan-Meier method and Cox proportional hazard model. Objective response rate (ORR), disease control rate (DCR) and safety are reported. Results: Baseline characteristics in the pooled population were generally balanced between trt arms in each subgroup. Median durations of prior SOR were 2.5 mo for SOR intolerant (n = 70) and 4.0 mo for SOR progressors (n = 472). Median OS (RAM v P) was 10.2 v 6.7 mo for SOR intolerant and 8.0 v 4.7 mo for SOR progressors (Table). Rates of D/C due to trt-related adverse events (AEs) (Table) (7% in each subgroup), and Grade ≥3 AEs (most frequently hypertension) were consistent with those observed in each study. Conclusions: Acknowledging limitations of sample size, the RAM trt benefit in SOR intolerant pts was consistent with that in the ITT population. RAM was well tolerated in SOR intolerant pts with low rates of D/C due to related-AEs. Clinical trial information: NCT01140347, NCT02435433. [Table: see text]

Abstract
BACKGROUND Carriers of the ALDH2*2 allele have impaired alcohol metabolism and are more susceptible to the development of alcohol-related cancers, including head and neck cancer (HNC). Screening for ALDH2*2 allele may identify high-risk individuals for alcohol health education. Although genotyping of ALDH2 is the most accurate way to identify ALDH2 deficiency, it may not be practical due to the cost and requirement for genotyping service. METHODS This study evaluated the accuracy of the alcohol flushing questionnaire to identify ALDH2 deficiency in a case-control study of HNC conducted in Taiwan using data collected from 904 patients with HNC and 1,078 controls. RESULTS Overall, alcohol flushing questionnaire had a high sensitivity (89%) of identifying ALDH2*2 carriers among the control subjects and a good sensitivity (79%) among the patients with HNC. The sensitivity of the alcohol flushing questionnaire in identifying ALDH2*2 carriers was affected by alcohol use, with a lower sensitivity among individuals who consumed alcohol, particularly among current regular (drinking alcohol once per week or more) alcohol drinkers. CONCLUSIONS The current validation study showed that the alcohol flushing questionnaire may be a reasonable method to identify ALDH2-deficient individuals. However, current regular users of alcohol who reported no alcohol flushing may need to undergo genotyping of ALDH2 for a more accurate assessment of the ALDH2 status.

Abstract
TPS477 Background: Arginine depletion interferes with pyrimidine metabolism as well as DNA damage repair pathways, and preclinical data indicate that pairing pegylated arginine deiminase (ADI-PEG 20) with fluoropyrimidines or platinum enhances cytotoxicity in vitro and in vivo in HCC models. A prior phase 1 study of FOLFOX6 and ADI-PEG 20 established the safety and recommended phase 2 dose of the combination in pts with advanced gastrointestinal tumors (Harding et al. CCP 2018). For 23 treatment-refractory HCC pts who were treated at the recommended phase 2 dose on an expansion cohort of the phase 1, the objective response rate (ORR) was 21% (95% CI 7.5-43.7) and median progression-free survival (PFS) was 7.3 months. These data were favorable when compared to historic data for FOLFOX alone where the ORR was ~8% and PFS was 2.93 months and suggest greater clinical activity of the combination (Qin et al. JCO 2013). Prospective confirmation of these results is required. Methods: This is an international, multicenter, single-arm, open-label phase 2 trial of ADI-PEG 20 and FOLFOX6 for advanced HCC pts with Child-Pugh A liver function who progressed on ≥ 2 prior lines of prior systemic therapy (NCT02102022). The primary objective is to define the ORR by RECIST 1.1 as assessed by blinded independent central review. Secondary objectives include determination of safety, disease control rate (DCR), duration of response (DOR), PFS, overall survival (OS), serum arginine, citrulline and anti-ADI-PEG 20 levels over 24 weeks, and alpha-fetoprotein response. Eligible pts receive intravenous FOLFOX6 biweekly at standard doses and ADI-PEG 20 intramuscularly weekly at 36 mg/m.2 Cross-sectional imaging will be completed every 8 weeks until progression of disease. Based on a two-sided exact test of a one-sample proportion with an alpha of 0.05, under a presumed ORR of 22%, there is 80% power to yield 95% confidence interval of 15-26%, which will require 46 objective responses in 225 subjects. Futility will be assessed three times during the study based on having ORR data available for 56, 110, and 166 patients. This Phase 2 will be stopped for futility if the conditional power drops below 20% at any of these time points. Clinical trial information: NCT02102022.

Abstract
326 Background: REACH-2 (NCT02435433) demonstrated a significant survival benefit with RAM vs placebo in the second-line treatment of patients with advanced HCC and AFP ≥ 400 ng/mL. This analysis investigated changes in AFP during treatment, as well as potential relationships with survival or progression. Methods: Patients were randomized (2:1) to RAM 8 mg/kg IV or placebo Q2W plus best supportive care until disease progression or unacceptable toxicity. Serum AFP levels were measured at baseline and every 3 cycles. Percent change in AFP from baseline was analyzed at each time point up to Cycle 12 with descriptive statistics and Wilcoxon rank sum test between treatment arms. AFP response was defined as ≥ 20% decrease from baseline. The association between AFP progression and radiographic progression in each time interval was assessed by odds ratio [OR] and Fisher’s exact test. Time to AFP progression and time to radiographic progression (TTP) were evaluated by the Kaplan-Meier method and compared between treatment arms using a stratified log-rank test. AFP progression was defined as ≥ 20% increase from baseline. Hazard ratio (HR) was generated using a stratified Cox regression model. Results: AFP response was significantly higher with RAM compared with placebo (42.1% vs 10.5%, p < 0.0001). Overall survival (OS) was longer in patients with AFP response (13.5 months) than in patients without (6.7 months), irrespective of treatment (HR 0.470, p < 0.0001). The median percent increase in AFP level from baseline was smaller in the patient population treated with RAM (0.4%, 6.1%, 15.4%, 10.8%) than with placebo (45.7%, 98.5%, 122.2%, 91.3%) at Cycles 3, 6, 9 and 12, respectively. Time to AFP progression (HR 0.422, p < 0.0001) and TTP (HR 0.427, p < 0.0001) favored a RAM benefit; subsequent analyses demonstrated a strong association between AFP progression and radiographic progression at 6 weeks (OR 2.44, p < 0.0084) and at 12 weeks (OR 1.89, p = 0.0430). Conclusions: Changes in AFP levels were associated with TTP and OS. RAM prolonged time to AFP progression and radiographic TTP, and slowed the rate of AFP increase during treatment. Clinical trial information: NCT02435433.

Abstract
TPS176 Background: Gastric cancer is the 5th most frequently diagnosed cancer and the 3rd leading cause of cancer deaths. HER2/neu is overexpressed in 15% to 25% of patients with gastric cancer and associated with a poor prognosis. Monoclonal antibodies against HER2/neu have been shown to be effective but alternative treatments are needed due to cost and global availability issues. IMU-131 is a B-cell peptide vaccine composed of 3 B cell epitopes derived from the extracellular domain of HER2/neu. Polyclonal antibodies against IMU-131 peptides binding 3 separate regions (DIII, IV) of HER2/neu have been shown to elicit antitumor activity in vitro and a phase I study demonstrated safety and immunogenicity in Her-2 +/++ metastatic breast cancer patients. Fusion of the single peptides into a hybrid peptide conjugated to CRM197 in conjunction with the adjuvant Montanide (P467-CRM-Montanide) improved formulation and stability of the vaccine. With the present Phase 1b/2 trial performed in patients with HER2/neu overexpressing gastric or gastroesophageal junction (GEJ) adenocarcinoma, we hypothesized that administration of IMU-131 in addition to chemotherapy is safe and immunogenic, and will prolong survival and may delay tumor progression and/or reduce tumor burden. Methods: This study is an international open-label multicenter study performed in 16 Asian and Eastern European sites with a maximum of 18 patients enrolled in Phase 1b. This dose escalation study is designed to assess safety, tolerability, immunogenicity and recommended phase 2 dose (RP2D) of IMU-131. Each patient is administered three injections of IMU-131, at a single dose level on Days 0, 14, and 35, accompanied by chemotherapy cycles of cisplatin and 5-fluorouracil or capecitabine every 21 days. The RP2D will be evaluated in the dose expansion Phase 2 study with 68 patients being enrolled. Results: The study is ongoing with the completion of the phase 1b portion in 4Q18. Conclusions: No conclusions can be drawn at this time. Clinical trial information: NCT02795988.

Ramucirumab after sorafenib in patients with advanced hepatocellular carcinoma and increased α-fetoprotein concentrations (REACH-2): a randomised, double-blind, placebo-controlled, phase 3 trial. Lancet Oncol 2019; 20:282-296. [PMID: 30665869 DOI: 10.1016/s1470-2045(18)30937-9] [Citation(s) in RCA: 1093] [Impact Index Per Article: 218.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2018] [Revised: 12/01/2018] [Accepted: 12/04/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Patients with advanced hepatocellular carcinoma and increased α-fetoprotein concentrations have poor prognosis. We aimed to establish the efficacy of ramucirumab in patients with advanced hepatocellular carcinoma and α-fetoprotein concentrations of 400 ng/mL or higher. METHODS REACH-2 was a randomised, double-blind, placebo-controlled, phase 3 trial done at 92 hospitals, clinics, and medical centres in 20 countries. Eligible patients were aged 18 years or older and had histologically or cytologically confirmed hepatocellular carcinoma, or diagnosed cirrhosis and hepatocellular carcinoma, Barcelona Clinic Liver Cancer stage B or C disease, Child-Pugh class A liver disease, Eastern Cooperative Oncology Group (ECOG) performance statuses of 0 or 1, α-fetoprotein concentrations of 400 ng/mL or greater, and had previously received first-line sorafenib. Participants were randomly assigned (2:1) via an interactive web response system with a computer-generated random sequence to 8 mg/kg intravenous ramucirumab every 2 weeks or placebo. All patients received best supportive care. The primary endpoint was overall survival. Secondary endpoints were progression-free survival, proportion of patients achieving an objective response, time to radiographic progression, safety, time to deterioration in scores on the Functional Assessment of Cancer Therapy Hepatobiliary Symptom Index 8 (FHSI-8), and time to deterioration in ECOG performance status. We also pooled individual patient data from REACH-2 with data from REACH (NCT01140347) for patients with α-fetoprotein concentrations of 400 ng/mL or greater. Efficacy analyses were by intention to treat, whereas safety analyses were done in all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT02435433. FINDINGS Between July 26, 2015, and Aug 30, 2017, 292 patients were randomly assigned, 197 to the ramucirumab group and 95 to the placebo group. At a median follow-up of 7·6 months (IQR 4·0-12·5), median overall survival (8·5 months [95% CI 7·0-10·6] vs 7·3 months [5·4-9·1]; hazard ratio [HR] 0·710 [95% CI 0·531-0·949]; p=0·0199) and progression-free survival (2·8 months [2·8-4·1] vs 1·6 months [1·5-2·7]; 0·452 [0·339-0·603]; p<0·0001) were significantly improved in the ramucirumab group compared with the placebo group. The proportion of patients with an objective response did not differ significantly between groups (nine [5%] of 197 vs one [1%] of 95; p=0·1697). Median time to deterioration in FHSI-8 total scores (3·7 months [95% CI 2·8-4·4] vs 2·8 months [1·6-2·9]; HR 0·799 [95% CI 0·545-1·171]; p=0·238) and ECOG performance statuses (HR 1·082 [95% CI 0·639-1·832]; p=0·77) did not differ between groups. Grade 3 or worse treatment-emergent adverse events that occurred in at least 5% of patients in either group were hypertension (25 [13%] in the ramucirumab group vs five [5%] in the placebo group), hyponatraemia (11 [6%] vs 0) and increased aspartate aminotransferase (six [3%] vs five [5%]). Serious adverse events of any grade and cause occurred in 68 (35%) patients in the ramucirumab group and 28 (29%) patients in the placebo group. Three patients in the ramucirumab group died from treatment-emergent adverse events that were judged to be related to study treatment (one had acute kidney injury, one had hepatorenal syndrome, and one had renal failure). INTERPRETATION REACH-2 met its primary endpoint, showing improved overall survival for ramucirumab compared with placebo in patients with hepatocellular carcinoma and α-fetoprotein concentrations of at least 400 ng/mL who had previously received sorafenib. Ramucirumab was well tolerated, with a manageable safety profile. To our knowledge, REACH-2 is the first positive phase 3 trial done in a biomarker-selected patient population with hepatocellular carcinoma. FUNDING Eli Lilly.

Abstract
Poor oral hygiene may lead to overgrowth of pathogenic oral bacteria, which may induce chronic inflammation to promote the oncogenesis of oral squamous cell carcinoma (OSCC). This study investigated the association between oral bacterial profile and OSCC risk in a case-control study of 138 OSCC cases and 151 controls (88 cases and 90 controls for the discovery group and 50 cases and 61 controls for the validation group). Oral bacterial profiles were characterized by targeted sequencing of the 16S rRNA gene. Three species of periodontopathogenic bacteria, Prevotella tannerae, Fusobacterium nucleatum, and Prevotella intermedia, were associated with an increased OSCC risk. This association was modified by the genetic polymorphisms of TLR2 and TLR4. Use of alcohol, betel quids and cigarettes and poor oral hygiene were associated with a higher percentage of oral periodontopathogenic bacteria. The association between alcohol and periodontopathogenic bacteria was modified by the genetic polymorphism of ALDH2, with a stronger positive association observed among the ALDH2-deficient individuals. The percentage of periodontopathogenic bacteria was positively correlated with the level of salivary IL1β, an inflammatory cytokine. Overall, our results showed a positive association between periodontopathogenic bacteria and OSCC risk and this relationship may be influenced by lifestyle and genetic factors. Our results provided further biological support for the established association between poor oral hygiene and OSCC risk. This suggested that improving oral hygiene may reduce OSCC risk and should be part of a public health campaign to prevent the occurrence of OSCC.
