Efficacy of dupilumab in patients with uncontrolled, moderate-to-severe asthma recruited from Japanese centers in the phase 3 LIBERTY ASTHMA TRAVERSE study. Allergol Int 2023; 72:89-99. [PMID: 36114102 DOI: 10.1016/j.alit.2022.07.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 07/11/2022] [Accepted: 07/24/2022] [Indexed: 01/27/2023] Open
Abstract
BACKGROUND Safety and efficacy data for dupilumab beyond 1 year are lacking for patients from Japan with moderate-to-severe asthma. METHODS The TRAVERSE open-label extension (OLE) study (NCT02134028) assessed the safety and efficacy of dupilumab 300 mg every 2 weeks up to 96 weeks in 2282 patients who completed a previous dupilumab asthma study. The primary endpoint was incidence of treatment-emergent adverse events (TEAEs). Secondary endpoints included annualized severe exacerbation rate and change from parent study baseline in pre-bronchodilator forced expiratory volume in 1 second (FEV1), asthma control, quality of life, and blood eosinophil levels. Anti-drug antibodies (ADA) were evaluated. We report results in 160 (7.8% of exposed population) patients recruited from Japanese centers with non-oral corticosteroid (OCS)-dependent asthma rolled over from two parent studies, and in subgroups with a type 2 inflammatory phenotype. RESULTS TEAEs were consistent with the parent studies and the known safety profile of dupilumab. One patient permanently discontinued treatment due to TEAEs. Exacerbation rates remained low and were sustained to Week 96, as were improvements in pre-bronchodilator FEV1. Rapid, sustained improvements were observed in dupilumab-treated patients who previously received placebo in a parent study, while further improvements in exacerbation rates, asthma control, and asthma-related quality of life were observed in those continuing dupilumab. Blood eosinophil levels decreased progressively while on treatment. Treatment-emergent ADA responses were highest in patients who had previously received placebo. Efficacy results were consistent in patients with a type 2 phenotype. CONCLUSIONS Long-term dupilumab treatment was well tolerated and efficacious in patients with non-OCS-dependent, moderate-to-severe asthma recruited from Japan.

Abstract
BACKGROUND Previous clinical trials have demonstrated the potential efficacy of poly (ADP-ribose) polymerase (PARP) inhibitors (PARPis) in patients with cancer involving homologous recombination repair (HRR) gene-mutation. Moreover, HRR gene-mutated cancers are effectively treated with immune checkpoint inhibitors (ICIs) with the increase in tumor mutation burden. We have proposed to conduct a multicenter, single-arm phase II trial (IMAGENE trial) for evaluating the efficacy and safety of niraparib (PARPi) plus programmed cell death-1 inhibitor combination therapy in patients with HRR gene-mutated cancers who are refractory to ICIs therapy using a next generation sequencing-based circulating tumor DNA (ctDNA) and tumor tissue analysis. METHODS Key eligibility criteria for this trial includes HRR gene-mutated tumor determined by any cancer gene tests; progression after previous ICI treatment; and Eastern Cooperative Oncology Group Performance Status ≤ 1. The primary endpoint is the confirmed objective response rate (ORR) in all patients. The secondary endpoints include the confirmed ORR in patients with HRR gene-mutation of ctDNA using the Caris Assure (CARIS, USA). The target sample size of the IMAGENE trial is 57 patients. Biomarker analyses will be performed in parallel using the Caris Assure, proteome analysis, and T cell repertoire analysis to reveal tumor immunosurveillance in peripheral blood. EXPECTED OUTCOME Our trial aims to confirm the clinical benefit of PARPi plus ICI combination therapy in ICI-resistant patients. Furthermore, through translational research, our trial will shed light on which patients would benefit from the targeted combination therapy for patients with HRR gene-mutated tumor even after the failure of ICIs. TRIAL REGISTRATION The IMAGENE trial: jRCT, Clinical trial no.: jRCT2051210120, Registered date: November 9, 2021.

Abstract
BACKGROUND Information on changes in asthma prevalence and the treatment status for asthma is used as basic information for taking medical and administrative measures against asthma. However, this information among adults is relatively limited. METHODS To elucidate changes in the prevalence of asthma and treatment status over time among Japanese adults, health insurance claim data from some health insurance societies covering salaried employees and their dependents were studied longitudinally. Claim data from FY1999 to 2007 were obtained from two health insurance societies, and data from FY 2011 to 2019 were obtained from three different health insurance societies, and changes in standardized asthma prevalence among subjects aged 20-59 years, proportion of asthma patients prescribed ICS, leukotriene receptor antagonist (LTRA), and LABA, and the mean number of acute asthma exacerbations per year were analyzed. RESULTS The prevalence of asthma increased from 1.6% in 1999 to 3.0% in 2007 and 2.9% in 2011 to 4.6% in 2019. Increased trends in asthma prevalence from 2011 to 2019 were more noticeable in subjects in their 50s than those in their 20s for both sexes. The number of emergency visits related to asthma was 1.5 per year in 1999, which decreased to 0.8 per year in 2019. The proportion of people prescribed all anti-asthma medications (ICS, LTRA, and LABA) increased over time. CONCLUSIONS The prevalence of adult asthma among Japanese salaried employees and their dependents has increased over the last 20 years, suggesting more attention should be paid to the prevention of this disease in adults.

Abstract
Background: Childhood asthma is a major risk for low lung function in later adulthood, but what factors in asthma are associated with the poor lung function during childhood is not known. Objective: To identify clinical factors in children with asthma associated with low or declining lung function during the treatment. Methods: We enrolled children with asthma who had been treated throughout three age periods, i.e., 6−9, 10−12, and 13−15 years old, at seven specialized hospitals in Japan. Clinical information and lung function measurements were retrieved from the electronic chart systems. To characterize the lung function trajectories during each age period, we evaluated the forced expiratory volume 1 (FEV1) with % predicted values and individual changes by the slope (S) from linear regression. We defined four trajectory patterns: normal (Group N) and low (Group L), showing %FEV1 ≥80% or <80% throughout all three periods; upward (Group U) and downward (Group D), showing S ≥ 0 or S < 0%. Logistic regression analysis was performed to compare factors associated with the unfavorable (D/L) versus favorable (N/U) groups. Results: Among 273 eligible patients, 197 (72%) were classified into Group N (n = 150)/U (n = 47), while 76 (28%) were in Group D (n = 66)/L (n = 10). A history of poor asthma control, long-acting beta2 agonist use, and a lower height Z-score during 13−15 years were associated with an unfavorable outcome (Group D/L). Conversely, inhaled corticosteroid (ICS) use during 10−12 years and high-dose ICS use during 13−15 years were associated with a favorable outcome (Group N/U). Conclusion: We identified several factors that are associated with unfavorable lung function changes in pediatric asthma. Attention should be paid to the possible relationship between yearly changes in lung function and poor asthma control, use of ICS (and its dose) and use of LABA.

Abstract
Abstract
Introduction
The electrical pulmonary vein (PV) isolation has been established as a curative therapy for paroxysmal atrial fibrillation (AF). Arctic Front™cryoballoon has been used worldwide for AF cryoablation. Recently, a new cryoballoon, POLARxTM CRYOABLATION system have been introduced, of which material of the balloon is softer and the N2O gas flow rate is higher.
Purpose
The aim was to investigate the procedural parameter and efficacy of POLARx comparing with Arctic Front.
Methods
This retrospective single center study included 101 consecutive patients who underwent paroxysmal AF ablation using cryoballoon at Keio University hospital from April 2021 to March 2022. The procedural data including the cryoballoon temperature and the number and duration of cryoablation were compared between POLARx (POLARx group) and ARCTIC FRONT ADVANCE PRO (AFA group). After the cryoablation, we added the radiofrequency application in order to maximize the isolated area when the voltage was remained inside PV (Figure 1). The necessities of the additional radiofrequency applications were also compared.
Results
In the present study, 64 patients in AFA group and 37 patients in POLARx group were analyzed. POLARx group included younger population and less females (62.8±9.9 vs 67.5±9.4 year of age, P=0.02; 13.5 vs 32.8%, P=0.04). There was no significant difference in comorbidities and examination data such as left atrium diameter or brain natriuretic peptide level. The minimal cryoballoon temperatures reached in POLARx group were lower than AFA group (−59.3±6.2 vs −47.7±7.5°C, P<0.01). No difference was found in the total number and duration of cryoablation and the time to isolate PV (6.1±2.1 vs 5.9±1.6, P=0.69; 790.2±256.1 vs 776.1±235.0 sec, P=0.69; 41.8±21.3 vs 47.1±29.6 sec, P=0.44, respectively). With regard to individual PVs, the total number and duration were tended to be larger at right superior PV in POLARx group (1.9±1.1 vs 1.4±0.7, P=0.01; 231.8±123.8 vs 193.2±83.0 sec, P=0.07), while there was no significant difference at the other PVs. The rate of successful PV isolation by a single cryo-application was not different between AFA and POLARx group (54.3 vs 61.4%, P=0.17). The additional radiofrequency applications were more frequent in AFA group (14.8 vs. 4.9%, P=0.003). There was a significant difference at right inferior PV (32.8 vs 8.1%, P=0.01), while not at left superior PV, left inferior PV and right superior PV (9.4 vs 2.9%, P=0.42; 9.4 vs 5.7%, P=0.71; 7.8 vs 2.7%, P=0.41). Phrenic nerve injury was occurred 1 case in both group and esophageal ulcer was occurred in 1 case in AFA group. No other complication including cardiac tamponade was occurred.
Conclusion
The total number and duration of cryoablation were not significantly different between AFA and POLARx group, except for right superior PV. There was an advantage in largely isolating right inferior PV in POLARx group comparing with AFA group.

Abstract
This article covers the salient and updated themes of the Japanese Pediatric Guidelines for the Treatment and Management of Asthma (JPGL) 2020 published by the Japanese Society of Pediatric Allergy and Clinical Immunology. In the 2020 guidelines, five new clinical questions (CQs) have been added to address the 12 CQs regarding the treatment of childhood asthma. "Infant and preschool asthma" is diagnosed when young children (<6 years of age) have three or more episodes of clear expiratory wheezing, which continue for more than 24 h, and symptom improvement can be observed after beta-2 agonist inhalation. In children without clear improvement, diagnostic therapeutic trial for the duration of 1 month with controller treatment can be used. Since long-term management is initiated, the treatment level is adjusted based on the current control status and the management of risk factors, with the provision for holistic care. This underscores the smooth transition of pediatric patients into adult services. There are several differences between the JPGL and the guidelines of other countries. Further evidence is obtained as the utility of the newly proposed management plans should be evaluated in the Japanese population.

Abstract
Colorectal cancer (CRC) is one of the most common malignant diseases. Generally, stoma construction is performed following surgery for the resection of the primary tumor in patients with CRC. The association of CRC with the gut microbiota has been widely reported, and the gut microbiota is known to play an important role in the carcinogenesis, progression, and treatment of CRC. In this study, we compared the microbiota of patients with CRC between with and without a stoma using fecal metagenomic sequencing data from SCRUM-Japan MONSTAR-SCREEN, a joint industry-academia cancer research project in Japan. We found that the composition of anaerobes was reduced in patients with a stoma. In particular, the abundance of Alistipes, Akkermansia, Intestinimonas, and methane-producing archaea decreased. We also compared gene function (e.g., KEGG Orthology and KEGG pathway) and found that gene function for methane and short-chain fatty acids (SCFAs) production was underrepresented in patients with a stoma. Furthermore, a stoma decreased Shannon diversity based on taxonomic composition but increased that of the KEGG pathway. These results suggest that the feces of patients with a stoma have a reduced abundance of favorable microbes for cancer immunotherapy. In conclusion, we showed that a stoma alters the taxonomic and functional profiles in feces and may be a confounding factor in fecal microbiota analysis.

Abstract
BACKGROUND Anaphylaxis following influenza vaccination is a rare but serious problem. The underlying immune responses are not well understood. This study elucidated the IgE and IgG antibody responses in healthy children and adolescents following inactivated influenza vaccines (IIVs). METHODS The efficacy and safety of quadrivalent IIV (QIV) and trivalent IIV (TIV) were compared in healthy subjects aged 0-18 years. Serum IIV-specific IgE, IgG, and IgG4 levels (sIgE, sIgG, and sIgG4) were measured with ImmunoCAP. Hemagglutination inhibition (HI) assay was performed for each influenza virus subtype. Sera from earlier patients who developed anaphylaxis to different IIVs were similarly tested. RESULTS A total of 393 subjects were enrolled: 96 were 6 months-2 years old, 100 were 3-5 years old, 100 were 6-12 years old, and 97 were 13-18 years old. No anaphylaxis was observed. Generally, QIV and TIV induced similar antibody responses. IIV-sIgE levels rose significantly after vaccination in the 6 months-2 years old and 3-5 years old groups, did not change in the 6-12 years old group, and decreased in the 13-18 years old group. In contrast, the IIV-sIgG4/sIgE ratio increased significantly after vaccination in all age groups. Sensitized subjects had significantly higher HI titers and IIV-sIgG levels in the youngest age group and higher IIV-sIgG4 levels in all age groups compared with the non-sensitized. The IIV-sIgG4/sIgE ratio in five patients with anaphylaxis was significantly lower than in age-matched healthy subjects. CONCLUSION IIVs induce IgE sensitization in healthy children but also robust IgG4 responses that may protect them from anaphylaxis.

Abstract
This is an abridged edition of English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, the description about three new drugs, namely, dupilumab, delgocitinib, and baricitinib, has been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
Background The addition of induction chemotherapy (IC) before chemoradiotherapy (CRT) has improved survival over CRT alone in locoregionally advanced nasopharyngeal cancer (LA-NPC). Nevertheless, this population would benefit from further development of a novel IC regimen with satisfactory efficacy and a more favorable safety profile. Methods We retrospectively assessed 29 LA-NPC patients who received the combination of paclitaxel (PTX), carboplatin (CBDCA), and cetuximab (Cmab) (PCE) as IC (IC-PCE) at the National Cancer Center Hospital East between March 2017 and April 2021. IC-PCE consisted of CBDCA area under the plasma concentration-time curve (AUC) = 1.5, PTX 80 mg/m2, and Cmab with an initial dose of 400 mg/m2 followed by 250 mg/m2 administered weekly for a maximum of eight weeks. Results Patient characteristics were as follows: median age, 59 years (range 24–75); 0, 1 performance status (PS), 25, 4 patients; and clinical stage III/IVA/IVB, 6/10/13. The median number of PCE cycles was 8(1-8). After IC-PCE, 26 patients received concurrent cisplatin and radiotherapy (CDDP-RT), one received concurrent carboplatin/5-fluorouracil and radiotherapy (CBDCA/5-FU-RT), and two received RT alone. The % completion of CDDP-RT was 88.5%. The response rate was 75.9% by IC and 100% at completion of CRT. The 3-year recurrence-free survival, locoregional failure-free survival, distant recurrence-free survival, and overall survival were 75.9%, 79.3%, 84.3%, and 96.3%, respectively. The incidence of adverse events of grade 3/4 was 34.5% during IC and 44.8% during CRT. Conclusion IC-PCE is feasible and effective for LA-NPC and may be a treatment option for this disease.

Int J Clin Oncol 2022; 27:1669-1674. [PMID: 35943644 DOI: 10.1007/s10147-022-02226-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Accepted: 07/26/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Cetuximab (Cmab) plays an important role in the treatment for recurrent or metastatic head and neck cancer (R/M HNC). To date, however, no safety data on biweekly administration of cetuximab at a dose of 500 mg/m2 (biweekly Cmab) for Japanese HNC patients have been available. METHODS We retrospectively reviewed the clinical records of five R/M HNC patients who received biweekly Cmab in our institute between January 2016 and September 2021 and compared the safety profile between two phases of weekly 250 mg/m2 and biweekly 500 mg/m2 Cmab in the identical patients. RESULTS All patients initially received Cmab in combination with chemotherapy. Chemotherapy consisted of paclitaxel plus carboplatin in two patients, cisplatin + 5-FU in one patient, and paclitaxel in two patients. Three patients switched treatment schedule from weekly Cmab to biweekly Cmab, while two patients received biweekly Cmab after completion of chemotherapy. The main reason for switching to biweekly Cmab was an unacceptably long commuting time to the hospital. The median duration of Cmab was 217 days (49-321) during weekly Cmab with or without chemotherapy and 42 days (28-175) during biweekly Cmab. Median dose of biweekly Cmab was 4 (3-12). During biweekly Cmab, worsened (Grade ≥ 2) toxicities were observed in two patients: one with grade 2 dry skin and the second with grade 2 skin infection. None developed grade ≥ 3 adverse events or discontinued treatment due to Cmab-related adverse events. CONCLUSION Biweekly Cmab was well tolerated and did not demonstrate severe toxicities related to Cmab for R/M HNC.

Abstract
1029 Background: Approximately 5-10% of breast cancer are hereditary. Variant allele frequency (VAF) of hereditary breast cancer predisposition genes in circulating tumor DNA (ctDNA) may be useful for detecting presumed germline pathogenic variants. Methods: One hundred and sixty-eight patients with advanced breast cancer (ABC) who underwent ctDNA and tumor tissue sequencing analyses in the SCRUM-Japan MONSTAR-SCREEN, a cancer genome screening project in Japan, from December 2019 to November 2021 were included. The patients were tested and monitored for their genomic alterations by FoundationOne Liquid assay or FoundationOne Liquid CDx assay. The pathogenic variants (PV) of hereditary breast cancer predisposition genes with VAF of 30% or higher in ctDNA were defined as PGPV. The VAF of BRCA1/2 on ctDNA analyses in BRCA1/2 germline pathogenic variant (GPV) carriers and the prevalence of PGPV in five hereditary breast cancer predisposition genes, including ATM, BRCA1, BRCA2, CHEK2, and PALB2, were investigated. Results: From 168 patients with ABC, including 115 Luminal, 32 HER2-positive, and 21 triple negative breast cancer, with a median age of 58 years, 39 PVs in 5 genes were identified with a median VAF of 0.62% (range: 0.1-84.77). ctDNA identified GPV of known BRCA1/2 GPV carriers (1 with BRCA1 and 6 with BRCA2) , with a median VAF of 51.4% (range: 48.2-77.5). The VAF of GPV on ctDNA were higher than 30% in subsequent consecutive samples. Among 161 patients with ABC, excluding 7 known BRCA1/2 GPV carriers, 6 PGPV (1 with BRCA1, 3 with BRCA2, and 2 with PALB2) were detected, with a median VAF of 65.5% (range: 51.2-84.8). Subsequent confirmatory tests were performed for two PGPV, and the variants were confirmed to be of germline origin. Conclusions: VAF on ctDNA analysis can help to easily detect PGPV of hereditary breast cancer predisposition genes. The PGPV detected in ctDNA analysis should be validated by established germline tests, and the results could provide opportunities for targeted therapies, as well as cancer risk assessment of patients and their relatives.

Abstract
Background: Allergen-specific immunotherapy is currently the only disease-modifying treatment for allergic asthma, and it has been shown to improve control of asthma while reducing both drug use and asthma exacerbations. However, its effects on lung function—especially its long-term effects—remain controversial. We aimed to identify factors associated with a possible beneficial effect of allergen-specific immunotherapy on lung function in asthma by retrospectively evaluating the long-term changes in lung function in children with asthma who received house dust mite subcutaneous immunotherapy (HDM-SCIT). Methods: We enrolled children with asthma who had undergone HDM-SCIT for more than 1 year. Clinical information and lung function measurements were retrieved from the electronic chart system. To characterize the trajectory of lung function change, we performed linear regression analysis to evaluate the maximal expiratory flow at 50% of the forced vital capacity during two periods: before and during HDM-SCIT. Slopes from a least-squares regression line for the two periods, i.e., S1 before HDM-SCIT and S2 during HDM-SCIT, were compared. The subjects were then classified into two groups: an improving group (Group I) defined as S2 − S1 > 0, and a declining group (Group D) defined as S2 − S1 < 0. The clinical factors at the start of HDM-SCIT were compared between the two groups. Results: A total of 16 patients were analyzed. Eight patients were classified into each of Group I and Group D. The mean ages were 10.5 and 11.8 years, and the mean treatment periods were 4.1 and 3.9 years. Group I had a significantly lower blood eosinophil count and a significantly higher HDM-specific IgE level than Group D. Logistic regression showed a strong relationship between those two markers and the lung function trajectory. Conclusion: Control of the blood eosinophil count in highly HDM-sensitized patients may increase the beneficial effect of HDM-SCIT on lung function.

Abstract
BACKGROUND Eosinophilic cationic protein (ECP) is associated with airway inflammation and asthma. However, the clinical value of measuring ECP in childhood asthma is not fully known. We aimed to study the diagnostic performance of serum ECP and other common asthma biomarkers, individually and in combinations. METHODS In a cross-sectional study, 5-16-year-old children with current asthma (CA) (n = 37), transient asthma (TA) (n = 43), (previous history of wheezing/asthma), and healthy children (HC) (n = 86) were investigated for ECP, blood eosinophil count (B-Eos), fractional exhaled nitric oxide (FeNO), and lung function, i.e., spirometry (forced expiratory volume during the first second [FEV1]/forced vital capacity [FVC] ratio). RESULTS Both ECP and B-Eos were higher in CA compared to TA (p < 0.01) and HC (p < 0.0001). ECP and B-Eos were also higher in TA compared to HC (p < 0.05 and p < 0.001, respectively). FeNO was higher in CA (p < 0.0001) and TA (p < 0.01) compared to HC but similar between the asthma groups. The FEV1/FVC ratio was lower in CA compared to TA and HC (both p < 0.01) but similar between TA and HC. The best diagnostic performance regarding CA was found for ECP and B-Eos with receiver operating characteristics area under curve (AUC) of 0.801 and 0.810, respectively. The optimal cutoff for ECP (29 μg/L) yielded a sensitivity and specificity of 70.3% and 81.4%. The corresponding AUCs for FeNO and FEV1/FVC were 0.732 and 0.670, respectively. ECP and B-Eos showed the highest AUCs (0.669 and 0.673) for differentiation between CA and TA. Combining ECP with FeNO and FEV1/FVC increased the odds ratio (OR) for having CA from OR 3.97-10.3 for the single biomarkers to OR 20.2 (95% confidence interval: 5.76-68.6). CONCLUSION Our results show that serum ECP is a reliable biomarker in the diagnosis of childhood asthma, with additional value in combination with FeNO and FEV1/FVC, and that ECP can be an alternative to B-Eos.
