Abstract
INTRODUCTION IMpower110 previously revealed significant overall survival (OS) benefit with atezolizumab versus chemotherapy in patients with treatment-naive EGFR- and ALK-negative (wild type [WT]) metastatic NSCLC with high programmed death-ligand 1 (PD-L1) expression (≥50% on tumor cells [TCs] or ≥10% on tumor-infiltrating immune cells [ICs], per SP142 immunohistochemistry assay; p = 0.0106). We present primary OS analyses in lower PD-L1 expression groups and an updated, exploratory analysis in the high PD-L1 expression group. METHODS This open-label, phase 3 trial randomized patients with PD-L1 expression on greater than or equal to 1% of TC or IC to receive atezolizumab or platinum-based chemotherapy. The primary end point was OS, hierarchically tested in PD-L1 expression WT subgroups: first the high PD-L1 expression subgroup, then the high-or-intermediate PD-L1 expression subgroup (≥5% on TC or IC), and then the any PD-L1 expression subgroup (≥1% on TC or IC). RESULTS The any PD-L1 expression WT population included 554 patients (excluded 18 EGFR- or ALK-positive patients). With 17 months' additional follow-up, OS improvement in the atezolizumab versus chemotherapy arm was not statistically significant in high-or-intermediate PD-L1 expression WT patients (n = 328; hazard ratio = 0.87, 95% confidence interval: 0.66-1.14, p = 0.3091; median = 19.9 versus 16.1 mo), precluding formal OS testing in any PD-L1 expression WT patients. Exploratory analysis in high PD-L1 expression WT patients (n = 205) revealed maintained OS benefit in the atezolizumab arm (hazard ratio = 0.76, 95% confidence interval: 0.54-1.09; median = 20.2 versus 14.7 mo). Updated safety data continued to favor atezolizumab. CONCLUSIONS Statistical significance for OS was not revealed in the high-or-intermediate expression WT group, and, as a result, OS in the any PD-L1 expression WT group was not formally tested. No new safety signals were found. This updated analysis of IMpower110 supports using atezolizumab in treatment-naive, metastatic WT NSCLC with high PD-L1 expression.

Abstract
BACKGROUND Gaining insights that cannot be obtained from health care databases from patients has become an important topic in pharmacovigilance. OBJECTIVE Our objective was to demonstrate a use case, in which patient-generated data were incorporated in pharmacovigilance, to understand the epidemiology and burden of illness in Japanese patients with systemic lupus erythematosus. METHODS We used data on systemic lupus erythematosus, an autoimmune disease that substantially impairs quality of life, from 2 independent data sets. To understand the disease's epidemiology, we analyzed a Japanese health insurance claims database. To understand the disease's burden, we analyzed text data collected from Japanese disease blogs (tōbyōki) written by patients with systemic lupus erythematosus. Natural language processing was applied to these texts to identify frequent patient-level complaints, and term frequency-inverse document frequency was used to explore patient burden during treatment. We explored health-related quality of life based on patient descriptions. RESULTS We analyzed data from 4694 and 635 patients with systemic lupus erythematosus in the health insurance claims database and tōbyōki blogs, respectively. Based on health insurance claims data, the prevalence of systemic lupus erythematosus is 107.70 per 100,000 persons. Tōbyōki text data analysis showed that pain-related words (eg, pain, severe pain, arthralgia) became more important after starting treatment. We also found an increase in patients' references to mobility and self-care over time, which indicated increased attention to physical disability due to disease progression. CONCLUSIONS A classical medical database represents only a part of a patient's entire treatment experience, and analysis using solely such a database cannot represent patient-level symptoms or patient concerns about treatments. This study showed that analysis of tōbyōki blogs can provide added information on patient-level details, advancing patient-centric pharmacovigilance.

Abstract
BACKGROUND The efficacy and safety of the anti-programmed death ligand 1 (PD-L1) monoclonal antibody atezolizumab, as compared with those of platinum-based chemotherapy, as first-line treatment for patients with metastatic non-small-cell lung cancer (NSCLC) with PD-L1 expression are not known. METHODS We conducted a randomized, open-label, phase 3 trial involving patients with metastatic nonsquamous or squamous NSCLC who had not previously received chemotherapy and who had PD-L1 expression on at least 1% of tumor cells or at least 1% of tumor-infiltrating immune cells as assessed by the SP142 immunohistochemical assay. Patients were assigned in a 1:1 ratio to receive atezolizumab or chemotherapy. Overall survival (primary end point) was tested hierarchically according to PD-L1 expression status among patients in the intention-to-treat population whose tumors were wild-type with respect to EGFR mutations or ALK translocations. Within the population with EGFR and ALK wild-type tumors, overall survival and progression-free survival were also prospectively assessed in subgroups defined according to findings on two PD-L1 assays as well as by blood-based tumor mutational burden. RESULTS Overall, 572 patients were enrolled. In the subgroup of patients with EGFR and ALK wild-type tumors who had the highest expression of PD-L1 (205 patients), the median overall survival was longer by 7.1 months in the atezolizumab group than in the chemotherapy group (20.2 months vs. 13.1 months; hazard ratio for death, 0.59; P = 0.01). Among all the patients who could be evaluated for safety, adverse events occurred in 90.2% of the patients in the atezolizumab group and in 94.7% of those in the chemotherapy group; grade 3 or 4 adverse events occurred in 30.1% and 52.5% of the patients in the respective groups. Overall and progression-free survival favored atezolizumab in the subgroups with a high blood-based tumor mutational burden. CONCLUSIONS Atezolizumab treatment resulted in significantly longer overall survival than platinum-based chemotherapy among patients with NSCLC with high PD-L1 expression, regardless of histologic type.

Abstract
9594 Background: IMpower110 (NCT02409342) evaluated atezo (anti–PD-L1) monotherapy as 1L treatment in PD-L1–selected patients (pts) with metastatic NSCLC and met its primary endpoint with statistically significant and clinically meaningful OS benefit in TC3 or IC3 wild-type (WT; EGFR/ALK-negative) pts. PROs were prespecified endpoints to assess pt perspectives on overall clinical benefit. Methods: Pts were randomized 1:1 to receive atezo 1200 mg IV q3w (Arm A) or platinum-based chemo (Arm B; 4 or 6 21-day cycles). Arm B non-squamous pts received cisplatin (cis) 75 mg/m2 or carboplatin (carbo) AUC 6 + pemetrexed 500 mg/m2 IV q3w; Arm B squamous pts received cis 75 mg/m2 + gemcitabine (gem) 1250 mg/m2 or carbo AUC 5 + gem 1000 mg/m2 IV q3w. PROs were assessed by the EORTC Quality of Life Questionnaire Core 30 (QLQ-C30) and lung cancer module QLQ-LC13. Time to confirmed deterioration (TTD) in QLQ-LC13 lung cancer symptoms (secondary endpoint) and change from baseline (BL) in global health status (GHS), functioning and lung cancer symptoms (exploratory endpoints) were analyzed in TC3 or IC3-WT pts. Clinically meaningful change was defined as a ≥10-point deterioration from BL. Results: Completion rates at BL (atezo, n = 107; chemo, n = 98) were high in both arms for the QLC-C30 (90% atezo, 86% chemo) and the QLC-LC13 (89% atezo, 85% chemo), and remained > 80% at most visits. Mean BL scores for GHS, physical functioning, and role functioning were moderate, symptom burden was low, and all were similar in both arms. No differences in TTD were seen between arms for cough (HR, 0.98; 95% CI: 0.48, 2.03), chest pain (HR, 1.02; 95% CI: 0.47, 2.22), dyspnea (HR, 0.96, 95% CI: 0.57, 1.60), and 3-symptom composite score (HR, 0.92; 95% CI: 0.59, 1.44). Mean change in physical function from BL to wk 42 was modestly improved with atezo and greater than or similar to chemo. No clinically meaningful worsening in dyspnea, cough or chest pain was seen with atezo vs chemo. Mean change in cough and chest pain from BL numerically improved immediately after start of treatment and was maintained to wk 48 with atezo. Fatigue and nausea/vomiting scores numerically improved immediately with atezo and were maintained to wk 48. Conclusions: QLQ-C30 and QLQ-LC13 completion rates were high at BL and most study visits. TTD of lung cancer-related symptoms was similar in both arms, indicating pts’ low BL symptom burden was maintained for a similar duration. Pts receiving atezo vs chemo sustained numerical improvements in physical function and no worsening in lung cancer-related symptoms. Clinical trial information: NCT02409342 .

Abstract
e21623 Background: IMpower110 evaluated atezo mono in PD-L1–selected, chemo-naive patients (pts) with nonsquamous (nsq) or squamous (sq) NSCLC. At the interim analysis, IMpower110 met its primary OS endpoint, with a statistically significant and clinically meaningful improvement for atezo vs chemo in TC3 or IC3 wild-type ( EGFR/ALK-negative) pts. We report on the safety profile of atezo vs chemo in IMpower110. Methods: 572 pts with stage IV nsq or sq NSCLC, PD-L1 expression ≥ 1% on TC or IC and ECOG PS 0-1 were randomized 1:1 to receive atezo (1200 mg IV q3w) or chemo (4 or 6 21-day cycles). In the chemo arm, nsq pts received cisplatin (cis) 75 mg/m2 or carboplatin (carbo) AUC 6 + pemetrexed (pem) 500 mg/m2 IV q3w; sq pts received cis 75 mg/m2 + gemcitabine (gem) 1250 mg/m2 or carbo AUC 5 + gem 1000 mg/m2 IV q3w. Safety was assessed in all treated pts (safety evaluable [SE] population [pop]), regardless of PD-L1 expression or EGFR/ALK status. AEs were summarized per MedDRA v22.0 and severity graded per NCI CTCAE v4.0. Immune-mediated AEs (imAEs) were defined per a sponsor-specified list of terms, regardless of whether the events led to systemic glucocorticoid, endocrine therapy, or other immunosuppressants use. Results: At data cutoff (Sep 10, 2018) within the ITT pop, treatment (tx) was ongoing in 90 (atezo: 31.6%) and 25 (chemo: 8.7%) pts, with 13.7 mo of follow-up. Within the SE pop (atezo: n = 286, chemo: n = 263), atezo pts had longer tx exposure (5.3 mo) vs chemo pts (pem, 3.5 mo; gem, 2.6 mo; carbo, 2.3 mo; cis, 2.1 mo). Atezo had a favorable safety profile vs chemo (table); safety data were consistent with data from a pooled atezo mono pop. imAEs occurred in 40.2% (atezo) and 16.7% (chemo) of pts and were Grade (Gr) 3-4 in 6.6% and 1.5%, respectively. Conclusions: Atezo was better tolerated than chemo and imAEs were generally low grade. Overall, the safety experience with atezo mono in IMpower110 was consistent with its known safety profile; no new safety signals were identified. Clinical trial information: NCT02409342.

Abstract
BackgroundPD-L1/PD-1 inhibitors (CPI) as monotherapy or in combination with platinum-based doublet chemo (± bevacizumab) are 1L treatment options in metastatic NSCLC, with choice of agent(s) determined by PD-L1 expression. For patients (pts) who may be ineligible for combination therapy, CPI monotherapy remains an attractive treatment choice. IMpower110 evaluated atezo as 1L treatment in PD-L1–selected pts independent of tumor histology.MethodsIMpower110 enrolled 572 chemo-naive pts with stage IV nonsquamous (nsq) or squamous (sq) NSCLC, PD-L1 expression ≥ 1% on TC or IC, measurable disease by RECIST 1.1 and ECOG PS 0-1. Pts were randomized 1:1 to receive atezo 1200 mg IV q3w (Arm A) or platinum-based chemo (Arm B; 4 or 6 21-day cycles). Arm B nsq pts received cisplatin (cis) 75 mg/m2 or carboplatin (carbo) AUC 6 + pemetrexed 500 mg/m2 IV q3w; Arm B sq pts received cis 75 mg/m2 + gemcitabine (gem) 1250 mg/m2 or carbo AUC 5 + gem 1000 mg/m2 IV q3w. Stratification factors were sex, ECOG PS, histology and tumor PD-L1 status (TC1/2/3 and any IC vs TC0 and IC1/2/3). The primary endpoint of OS is tested hierarchically in the wild-type (WT; EGFR/ALK-negative) population (TC3 or IC3 then TC2/3 or IC2/3 then TC1/2/3 or IC1/2/3).ResultsThe 3 primary efficacy populations included 554 TC1/2/3 or IC1/2/3 WT pts, 328 TC2/3 or IC2/3 WT pts and 205 TC3 or IC3 WT pts. Median follow-up was 15.7 months (range, 0-35) in TC3 or IC3 WT pts. In the TC3 or IC3 WT population, atezo monotherapy improved median OS by 7.1 months (HR, 0.595; P = 0.0106) compared with chemo (table 1). The safety population comprised 286 pts in Arm A and 263 in Arm B. Treatment-related AEs (TRAEs) and Grade 3-4 TRAEs occurred in 60.5% (Arm A) and 85.2% (Arm B), and 12.9% (Arm A) and 44.1% (Arm B), respectively.Abstract 081 Table 1ConclusionsAt this interim analysis, IMpower110 met the primary endpoint of OS with statistically significant and clinically meaningful improvement in the TC3 or IC3 WT population. The safety profile favored Arm A, with no new or unexpected safety signals identified.Trial RegistrationNCT02409342Ethics ApprovalThe trial was conducted according to the principles of the Declaration of Helsinki. All patients provided written informed consent. Protocol approval was obtained from independent review boards or ethics committees at each site.

Abstract
Background Shorter duration of infusion of monoclonal antibody treatments may reduce treatment burden and improve healthcare resource utilization. Methods This phase II study recruited Japanese patients with previously untreated CD20+ B-cell non-Hodgkin lymphoma. Patients received intravenous obinutuzumab 1000 mg by regular infusion on Days 1, 8 and 15 of Cycle 1, followed by 90-min shorter duration of infusion in up to seven subsequent cycles, provided they received ≥3 regular infusions without any grade ≥3 infusion-related reactions and had a lymphocyte count <5.0 × 109 cells/l. Standard cyclophosphamide, doxorubicin, vincristine and prednisolone chemotherapy was given in Cycles 1-6. The primary endpoints were as follows: incidence of grade ≥3 infusion-related reactions in Cycle 2 in patients who started shorter duration of infusion in Cycle 2, serum obinutuzumab concentrations and pharmacokinetic parameters and the time course of cytokine release. Adverse events and serious adverse events were monitored. Results Of 35 patients treated, 28 completed eight cycles; 31 started shorter duration of infusion in Cycle 2 and two patients in subsequent cycles. Two patients discontinued before starting shorter duration of infusion. No grade ≥3 infusion-related reactions occurred in Cycle 2. Twenty-one infusion-related reactions (all grades 1-2) were reported in 17/35 (49%) patients overall, mostly in Cycle 1 (18/21 infusion-related reactions [86%]). Grade ≥3 AEs occurring in ≥10% of patients included neutropenia/neutrophil count decreased (66%) and leukopenia/white blood cell count decreased (23%). Steady-state pharmacokinetics of obinutuzumab were attained in Cycle 2 and were not affected by shorter duration of infusion. No relevant cytokine elevations were reported with shorter duration of infusion. Conclusions Regular infusion and shorter duration of infusion of obinutuzumab have comparable tolerability and pharmacokinetics in Japanese patients.

Abstract
OBJECTIVES We determined the central nervous system (CNS) efficacy of alectinib by calculating time to CNS progression and cumulative incidence rates (CIRs) of CNS progression, non-CNS progression and death in patients with anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) enrolled in the J-ALEX phase III study. MATERIALS AND METHODS Japanese patients aged ≥20 years with ALK-positive NSCLC who were ALK inhibitor-naïve and chemotherapy-naïve, or who had received one previous chemotherapy regimen, were enrolled. Patients with treated or untreated asymptomatic CNS metastases were eligible. Treatment comprised oral alectinib 300 mg twice daily or crizotinib 250 mg twice daily until progressive disease, unacceptable toxicity, death or withdrawal. Imaging scans (computed tomography/magnetic resonance imaging) were taken at baseline and at regular intervals throughout the study. The CIRs for CNS progression, non-CNS progression and death were calculated for patients with and without baseline CNS metastases using a competing risks method. RESULTS The hazard ratio for time to CNS progression in patients with and without baseline CNS metastases was 0.51 (95% confidence interval [CI]: 0.16-1.64; P = 0.2502) and 0.19 (95% CI: 0.07-0.53; P = 0.0004), respectively. The CIRs of CNS progression and non-CNS progression were lower in the alectinib group than in the crizotinib group at all time points. The 1-year CIRs of CNS progression were 16.8% and 5.9% with crizotinib and alectinib, respectively, and the 1-year CIRs of non-CNS progression were 38.4% and 17.5%, respectively. Comparable findings were obtained in patients with or without baseline CNS metastases. CONCLUSION Alectinib appears to avert the progression of CNS metastases in patients with ALK-positive NSCLC and baseline CNS metastases, and to prevent the development of new CNS lesions in patients without baseline CNS disease.

Abstract
Taselisib is a potent and selective phosphatidylinositide 3-kinase (PI3K) inhibitor. The present article reports the first study of taselisib administration in Japanese patients. The aim of this 2-stage, phase I, multicenter, open-label, dose-escalation study was to evaluate the safety, pharmacokinetics, and preliminary efficacy of taselisib as monotherapy in Japanese patients with advanced solid tumors (stage 1), and as part of combination therapy in Japanese patients with hormone receptor (HR)-positive locally advanced or recurrent breast cancer (stage 2). In stage 1, oral taselisib tablets 2, 4, and 6 mg/d were given in 28-day cycles. In stage 2, successive cohorts of patients received oral taselisib tablets (2 or 4 mg/d) with i.m. fulvestrant 500 mg. Nine and 6 patients were enrolled in stage 1 and stage 2, respectively. Taselisib was well tolerated. No dose-limiting toxicities were experienced in any cohort of patients and no deaths were observed. The most common treatment-related adverse events in stage 1 and stage 2, respectively, were rash (55.6%, 66.7%), diarrhea (44.4%, 66.7%), and stomatitis (44.4%, 66.7%). Taselisib was rapidly absorbed after dosage; its half-life was 12.9-32.0 hours in stage 1 and 16.1-26.5 hours in stage 2. Two patients achieved partial response (PR), 5 patients had stable disease (SD) and 2 patients had progressive disease (PD) in stage 1, and 1 patient had PR and 3 patients had SD in stage 2. All patients with PR were positive for PIK3CA gene mutations. These preliminary data suggest that taselisib may be effective in patients with PIK3CA-mutated solid tumors or HR-positive advanced breast cancer.

Abstract
BACKGROUND AVAGAST was an international, randomized, placebo-controlled phase III study of chemotherapy with or without bevacizumab as first-line therapy for patients with advanced gastric cancer. We performed exploratory analyses to evaluate regional differences observed in the trial. METHODS Analyses were performed in the placebo plus chemotherapy arm (intention-to-treat population). Chemotherapy was cisplatin 80 mg/m2 for six cycles plus capecitabine (1000 mg/m2 orally bid days 1-14) or 5-fluorouracil (800 mg/m2/day continuous IV infusion days 1-5) every 3 weeks until disease progression or unacceptable toxicity. RESULTS Overall, 387 patients were assigned to placebo plus chemotherapy (eastern Europe/South America, n = 118; USA/western Europe, n = 81; Korea/other Asia, n = 94; Japan, n = 94). At baseline, poor performance status, liver metastases, and larger tumors were most frequent in eastern Europe/South America and least frequent in Japan. Patients received subsequent chemotherapy after disease progression as follows: eastern Europe/South America (14%); USA/western Europe (37%); Korea/other Asia (61%); and Japan (77%). Hazard ratios for overall survival versus USA/western Europe were 1.47 (95% CI, 1.09-1.99) for eastern Europe/South America, 0.91 (95% CI, 0.67-1.25) for Korea/other Asia, and 0.87 (95% CI, 0.64-1.19) for Japan. CONCLUSIONS Regional differences in the healthcare environment may have contributed to the differences in overall survival observed in the AVAGAST study.

Abstract
9064 Background: ALC is a highly selective, CNS-active ALK tyrosine kinase inhibitor. In the J-ALEX study, ALC proved superior efficacy and tolerability compared to CRZ at the pre-planned interim analysis at 83 progression free survival (PFS) events (51% of target events) . Here we report the updated data with a further 10 months of follow up. Methods: Patients with advanced ALK+ NSCLC were randomized 1:1 to receive ALC 300 mg b.i.d or CRZ 250 mg b.i.d and stratified by ECOG PS, treatment line, and clinical stage. Study Treatment was continued until disease progression or unacceptable toxicity. The primary endpoint was PFS according to the blinded independent review. Secondary endpoints included investigator-assessed PFS, overall survival, objective response rate and safety. Results: From Nov 2013 to Aug 2015, 207 patients were enrolled. Data cut off for the present analysis was Sep 2016. Median durations of PFS follow up were 20.5 months in the ALC arm and 20.4 months in the CRZ arm with 116 events by independent review observed. The updated PFS HR was 0.38 (95% CI: 0.26-0.55, p< 0.0001). Median PFS was 25.9 months (95% CI: 20.3-not estimated) with ALC and 10.2 months (95% CI: 8.3-12.0) with CRZ. For patients without brain metastasis at baseline (n = 164), ALC prevented CNS metastasis onset compared to CRZ (HR = 0.19, 95% CI: 0.07-0.53). For patients with brain metastasis at baseline (n = 43), ALC also prevented CNS progression compared to CRZ (HR = 0.51, 95% CI: 0.16-1.64). Adverse events (AEs) with frequency of more than 30% were constipation (37.9%) and nasopharyngitis (32.0%) in the ALC arm, while in the CRZ arm nausea (76.0%), diarrhea (74.0%), vomiting (57.7%), visual disturbance (54.8%), dysgeusia (51.9%), constipation (46.2%), increased ALT (32.7%), and increased AST (31.7%) were observed. Grade 3-4 AEs occurred with greater frequency in the CRZ arm (ALC: 32.0% vs CRZ: 56.7%). There were no Grade 5 AEs in either arm. Conclusions: In the updated analysis, ALC consistently showed superior efficacy compared to CRZ in systemic disease and prevention of CNS progression. ALC was also associated with a more favorable tolerability profile than CRZ. Clinical trial information: JapicCTI-132316.

Abstract
Purpose Alectinib is an anaplastic lymphoma kinase (ALK) –specific kinase inhibitor that seems to be effective against non–small-cell lung cancer (NSCLC) with a variety of ALK mutations. The primary analysis of AF-001JP reported a promising overall response rate. To assess progression-free survival (PFS) and overall survival (OS), patients from the phase II part of AF-001JP were followed up for approximately 3 years. Patients and Methods Oral alectinib 300 mg was administered twice per day to patients with ALK inhibitor–naïve, ALK-positive NSCLC who had progressed after one or more regimens of previous chemotherapy. In this long-term follow-up, efficacy (PFS, OS), correlation between tumor shrinkage and PFS, safety of alectinib, and relief of cancer symptoms were evaluated. Results At the updated data cutoff (September 10, 2015; first patient in August 30, 2011, last patient in April 18, 2012), 25 of 46 phase II patients were still receiving alectinib. Disease progression was confirmed in 18 patients (39%); median PFS was not reached (3-year PFS rate, 62%; 95% CI, 45 to 75). Fourteen patients had brain metastases at baseline; of these, 6 remained in the study without CNS and systemic progression. Tumor shrinkage and PFS showed no correlation. The 3-year OS rate was 78% (13 events). The most common treatment-related adverse event (all grades) was increased blood bilirubin (36.2%). Most cancer symptoms were relieved early, and medication for symptoms was dramatically decreased during alectinib therapy. Conclusion Alectinib was effective in this 3-year follow-up with a favorable safety profile over a long administration period in ALK-positive NSCLC without previous ALK inhibitor treatment.

Abstract
BACKGROUND Although several reports have suggested that patient-generated data from Internet sources could be used to improve drug safety and pharmacovigilance, few studies have identified such data sources in Japan. We introduce a unique Japanese data source: tōbyōki, which translates literally as "an account of a struggle with disease." OBJECTIVE The objective of this study was to evaluate the basic characteristics of the TOBYO database, a collection of tōbyōki blogs on the Internet, and discuss potential applications for pharmacovigilance. METHODS We analyzed the overall gender and age distribution of the patient-generated TOBYO database and compared this with other external databases generated by health care professionals. For detailed analysis, we prepared separate datasets for blogs written by patients with depression and blogs written by patients with rheumatoid arthritis (RA), because these conditions were expected to entail subjective patient symptoms such as discomfort, insomnia, and pain. Frequently appearing medical terms were counted, and their variations were compared with those in an external adverse drug reaction (ADR) reporting database. Frequently appearing words regarding patients with depression and patients with RA were visualized using word clouds and word cooccurrence networks. RESULTS As of June 4, 2016, the TOBYO database comprised 54,010 blogs representing 1405 disorders. Overall, more entries were written by female bloggers (68.8%) than by male bloggers (30.8%). The most frequently observed disorders were breast cancer (4983 blogs), depression (3556), infertility (2430), RA (1118), and panic disorder (1090). Comparison of medical terms observed in tōbyōki blogs with those in an external ADR reporting database showed that subjective and symptomatic events and general terms tended to be frequently observed in tōbyōki blogs (eg, anxiety, headache, and pain), whereas events using more technical medical terms (eg, syndrome and abnormal laboratory test result) tended to be observed frequently in the ADR database. We also confirmed the feasibility of using visualization techniques to obtain insights from unstructured text-based tōbyōki blog data. Word clouds described the characteristics of each disorder, such as "sleeping" and "anxiety" in depression and "pain" and "painful" in RA. CONCLUSIONS Pharmacovigilance should maintain a strong focus on patients' actual experiences, concerns, and outcomes, and this approach can be expected to uncover hidden adverse event signals earlier and to help us understand adverse events in a patient-centered way. Patient-generated tōbyōki blogs in the TOBYO database showed unique characteristics that were different from the data in existing sources generated by health care professionals. Analysis of tōbyōki blogs would add value to the assessment of disorders with a high prevalence in women, psychiatric disorders in which subjective symptoms have important clinical meaning, refractory disorders, and other chronic disorders.

Abstract
Butirosin is an interesting 2-deoxystreptamine (DOS)-containing aminoglycoside antibiotic produced by non-actinomycete Bacilli. Recently we were successful in purification of 2-deoxy-scyllo-inosose synthase from butirosin-producer Bacillus circulans as the key enzyme for the biosynthesis of DOS, in cloning of the responsible gene (btrC), and in its overexpression in Escherichia coli. The present study involved gene-walking approach, which allowed us to find a gene cluster around btrC. The function of each gene was further investigated by gene disruption, and the disruptants of btrB, btrC, btrD and btrM showed no antibiotic producing activity. Therefore, the gene cluster found so far was determined to be a part of the butirosin biosynthetic gene cluster. Functions of some ORFs are also discussed in terms of butirosin biosynthesis on the basis of database search.

Abstract
Flow cytometry can be used for the detection of aberrations in DNA composition and DNA content of human chromosomes. We demonstrate here the magnitude of DNA content differences among normal chromosomes of 20 healthy individual donors and the clinical applications of the standardized bivariate flow karyotype. Peak positions were determined from Hoechst 33258 (HO) VS Chromomycin A3 (CA3) flow karyotypes of individuals, and the values of the relative chromosomal DNA content were normalized to the peak position constituting chromosomes 9-12, to which a value of 100 arbitrary units (a.u.) was assigned. The mean values and standard deviations that were HO and CA3 fluorescence intensity for each chromosome were calculated. The range of standard deviation is 1.43 to 6.21 (CA3) and is 1.22 to 4.28 (HO). The standard deviations for each chromosome did not overlap; therefore, it was decided that the standardized bivariate flow karyotype was suitable to use for clinical applications. Further study using fluorescence in situ hybridization for chromosome 22 that was observed for extra peak accompanied with normal peak in the flow karyotype of clinical material did not suggest more positive data. This suggests that the peak-position difference between chromosome 22 homologues may be a result of a combination of satellite and heterochromatic-region size differences.

Abstract
The effects of different swelling solutions on the univariate flow karyotype of whole chinese hamster embryo cells (WCHE K10) and cloned chinese hamster embryo fibroblast cells (CCHE 40) were compared using four methods of chromosome isolation. Chromosomes of each cell line were prepared by the Aten, Polyamine-Digitonin, Tris-Triton, and HEPES methods and analyzed with a FACStar flow cytometer. Polyamine-Digitonin and Aten methods produced the most satisfactory flow karyotype. Structurally aberrant chromosomes in the cell lines were detected in the flow karyotype as extra peaks. CCHE 40 chromosomes 1,2,X and 3q were sorted into separate tubes and reanalyzed; and the coefficient of variation of each chromosome peak was near 5%. To apply the flow karyotype analysis to clinical cytogenetics, chromosome preparation was one of the most important factor, and it is necessary to sort the chromosome peak sharply.

Abstract
The effect of reserpine on vascular and intestinal smooth muscles was examined. In these muscles, reserpine inhibited the high K(+)-induced contraction, and this inhibitory effect was antagonized by the increase in external Ca2+ concentration and also by a Ca2+ channel activator, Bay k8644. In rabbit aorta, increases in cytosolic Ca2+ level and muscle tension due to high K+ were inhibited in parallel by reserpine. These results suggest that reserpine inhibits L-type Ca2+ channels to inhibit smooth muscle contraction.

Abstract
A male newborn infant with a deletion of the short arm of chromosome 10p 14 was described. In addition to the typical clinical features, electrophysiologic studies showed brainstem dysfunction and severe hearing loss when examined with auditory brainstem response and photopalpebral reflex. These electrophysiologic studies may be of benefit for early evaluation of brainstem functions and hearing ability of the patients of such chromosomal aberration and may also be useful predictors of psychomotor development.

Abstract
We found phosphoinositide-specific phospholipase C (PtdIns-PLC) activity in nuclei isolated from rat liver. The enzyme hydrolyzed phosphatidylinositol, phosphatidylinositol 4-monophosphate (PIP) and phosphatidylinositol 4,5-bisphosphate in a Ca(2+)-dependent manner, and produced inositol mono-, bis-, and triphosphate, respectively. Neither phosphatidylcholine, phosphatidylethanolamine, nor phosphatidylserine was utilized as a substrate. After partial hepatectomy, the PtdIns-PLC activity in isolated nuclei increased transiently in the S phase (20-22 h post-hepatectomy), to 2.5-fold higher than in the control, when measured with PIP. This result suggests a close relationship between the nuclear PtdIns-PLC, especially its PIP-hydrolyzing activity, and cell proliferation.

Abstract
In order to discover the effect of external biliary drainage on liver regeneration, we have produced a model system carrying cannula in the common bile duct of rat liver and examined the regeneration capacity of liver after partial hepatectomy under various conditions. Previously we have shown that hepatic cells proliferate by obstructive jaundice alone without partial hepatectomy [Terasaki et al; Jpn J Cancer Res 1991;82:170-175]. In the present study, we showed that DNA polymerase-alpha was induced by partial hepatectomy of rats suffering from obstructive jaundice and the induced level was similar to that of the normal regenerating liver. The level of DNA polymerase-alpha activity corresponded well to the liver regeneration capacity estimated by mitotic index. Contrary to our expectation, external biliary drainage for obstructive jaundice markedly suppressed the regeneration capacity of the remaining liver which was estimated by DNA polymerase-alpha activity, mitotic index and [3H]thymidine incorporation. The suppression may be due to the external biliary drainage itself because the liver regeneration of normal rats without jaundice was also suppressed by the biliary drainage. These results suggest that the external biliary drainage seriously suppresses the regeneration capacity of liver at least at the early stage of obstructive jaundice.

Abstract
To know the possible relationships between nuclear phospholipids and cell proliferation, we have extensively analyzed phospholipids extracted from the nuclei of rat hepatic cells at various growth states. The content of phospholipid in nuclei as well as its composition was similar among liver cells tested, i.e., the regenerating rat livers (28 h, post-hepatectomy), sham-operated or non-treated control livers, and rat ascites hepatoma, AH7974 cells. In contrast, the fatty acid compositions of phospholipids differed from each other among these cells. At the 2-position of phospholipids in the regenerating liver nuclei at 28 h after partial hepatectomy, 18:1 (oleic acid) increased transiently at the expense of 20:4 (arachidonic acid) and 22:6 (docosahexaenoic acid), compared with those in the sham-operated control nuclei. This change in fatty acid composition was commonly observed throughout all phospholipids analyzed, i.e., phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI) and phosphatidylserine (PS). On the other hand, the change at 1-position was rather limited: in the regenerating liver nuclei (28 h), 18:1 increased only in PC at the expense of 18:0 (stearic acid). The similar and more marked deviation at the 2-position was observed with AH7974 nuclei it contained approximately 2-times more of 18:1 in PC, PE and PI than regenerating liver nuclei (28 h), and the decreased levels of 20:4 and/or 22:6. It should be noted that there were significant differences in the fatty acid compositions of PE and PS between sham-operated and non-treated controls. So, the sham-operated rat is the appropriate control for proliferation.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Obstructive jaundice, produced by ligating the common bile duct, induced a transient DNA replication followed by cell proliferation in rat liver. At 48 h after the operation, DNA polymerase alpha activity started to increase and reached its maximum level (more than twice the control) at day 4. At day 7, the enzyme level had decreased to the control level. Pulse-labeling experiment using radioactive thymidine showed that the rate of DNA synthesis increased approximately 2.5-fold in the same pattern as that of DNA polymerase alpha. The mitotic index in hepatocytes also increased 10-fold at day 4 and then decreased. The proliferation of liver cells induced by obstructive jaundice mimics the regeneration of partially hepatectomized liver, although the response was slightly delayed and the proliferation was transient.

Abstract
A 69-year-old woman with typical thrombotic thrombocytopenic purpura is reported, who was treated successfully by plasma exchange. An initial chromosomal analysis of peripheral blood lymphocytes revealed abnormal patterns of 45, XO/46, XX/47, XXX; a second analysis showed 45, XO/46, XX/47, XXX/47, XX + 21, and a third, performed in remission, showed a normal pattern. Skin fibroblasts showed a normal pattern even during the acute disease. The association of transient chromosomal aberrations and thrombotic thrombocytopenic purpura might be related to a viral infection.

Abstract
Membrane fluidity of rat neutrophils was studied following Escherichia coli inoculation, and characteristic changes were observed. Membrane fluidity was assessed by the excimer-forming lipid technique using pyrenedecanoic acid and flow cytometry and expressed as the fluorescence intensity ratios of excimer and monomer pyrenedecanoic acid (IE/IM ratio). High IE/IM ratios indicated high membrane fluidity. The IE/IM ratio of rat neutrophils (0.50 +/- 0.048) increased after E. coli inoculation, reaching a maximum of almost 1.00 after 10-20 min and then returning to its starting value. Intravenous injection of heat-killed E. coli or E. coli-conditioned culture supernatants into rats induced a rapid increase of IE/IM ratios, which returned to initial levels after 20 min. The effect on membrane fluidity of in vitro neutrophil incubation with E. coli, heat-killed E. coli, or E. coli-conditioned culture supernatants was similar to that observed in vivo. Addition of 5 mM ethylenediaminetetraacetic acid (EDTA) did not affect neutrophil membrane fluidity. Addition of either 5 micrograms/ml cytochalasin B or 10(-5) M colchicine did not directly affect neutrophil membrane fluidity but did block the change observed following incubation with bacteria.

Abstract
The anti-asthmatic activity of AA-2414 [(+/-)-7-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-7-phenylheptano ic acid] has been studied in vivo and in vitro. Experimental allergic asthma was inhibited by orally administered AA-2414 in a dose-dependent manner. AA-2414, 0.08-1.25 mg/kg (p.o.), inhibited the bronchconstriction in guinea pigs induced by a prostaglandin endoperoxide analogue (U-46619), leukotriene D4 (LTD4), and platelet activating factor (PAF) with a long duration of action. The compound did not inhibit histamine-induced bronchoconstriction. AA-2414 reduced the induction of pulmonary inflation caused by LTD4 aerosol inhalation. AA-2414 competitively inhibited the contractile response to U-46619 in guinea pig tracheal and parenchymal strips and dog saphenous vein strips with pA2 values of 7.69, 8.29 and 6.79, respectively. Furthermore, the contractile responses of guinea pig tracheal strip to PGD2, 9 alpha, 11 beta-PGF2 and PGF2 alpha were inhibited with pA2 values of 7.20, 7.79 and 5.71, respectively. These results suggest that AA-2414, a quinone derivative, is a novel, potent and orally active antagonist of a variety of spasmogenic prostanoids.

Abstract
The aortic endothelium of inherited cataract rats (ICR), which spontaneously develop cataracts and neutrophilia, was examined by scanning electron microscopy using silver nitrate staining and pressure fixation. In ICR aged 4 weeks, the luminal surface of the aorta was similar to that in Wistar rats from which they had been derived. However, 8 weeks after birth, endothelial cells were upraised and partially detached from an underlying tissue. At 16 weeks, morphological changes exhibited by such detaching cells were more evident than at 8 weeks and fibrin was seen to be adhering to the surface of these cells; no platelet involvement was noted, however. Oral administration of DL-alpha-tocopheryl acetate for 2 weeks resulted in a reduction in the extent of endothelial injury and the luminal surface of the aorta became similar to that seen in 4- or 8-week-old animals. We found that the number of age-associated spontaneous injuries occurring in the aortic endothelium of ICR could be reduced by tocopherol administration.

Abstract
The effect on guinea pig airways of the inhalation of leukotrienes, histamine or antigen was investigated by measuring changes in lung volume and analyzing the airway area on bronchograms with the Zeiss interactive image analysis system (IBAS). LTC4, LTD4, LTE4 and histamine inhaled through an ultrasonic nebulizer caused inflation of the lung: LTD4 was the most potent of the leukotrienes and was 100 times more potent than histamine on a molar basis. The results of analyses of areas of large and small bronchi and bronchioles on the bronchograms indicated that LTD4 selectively decreased the area of the peripheral airways. Inhalation of an antigen in actively sensitized animals resulted in inflation of the lung and in a selective decrease in the area of the peripheral airways. Anaphylactic bronchoconstriction provoked by antigen inhalation was clearly inhibited by AA-861, a 5-lipoxygenase inhibitor but not significantly by mepyramine, an antihistamine. These observations indicate that LTD4 is a potent constrictor of the peripheral airways in guinea pigs and that the anaphylactic bronchoconstriction provoked by antigen inhalation could be mediated by LTD4 in actively sensitized guinea pigs.

Abstract
A method was established for measuring membrane fluidity of polymorphonuclear leukocytes (PMN) by the excimer-forming lipid technique with pyrenedecanoic acid in flow cytometry. When cells were labeled, the use of 2-25 microM of pyrenedecanoic acid provided similar results. Neither the removal of the unincorporated pyrenedecanoic acid nor adjustment of PMN counts exhibited any effect. By the gate analysis method, membrane fluidity of PMN could be measured with 100 microliters of heparinized whole blood in a short time and results with PMN in whole blood was similar to those with purified PMN. Therefore, purification and count adjustment of PMN could be omitted. By this method, membrane fluidity of PMN, which were treated with membrane fluidizer, was measured successfully. This method could be applied to the study of PMN function in various diseases.

Abstract
Amlexanox markedly inhibits histamine release from rat mast cells. To clarify the mechanism of this inhibition, we investigated the effect of amlexanox on cAMP content, which, when increased, inhibits histamine release in rat peritoneal mast cells. At concentrations of 10(-8)-10(-6)M, amlexanox or isoproterenol increased the cAMP content of mast cells over that of control cells about 2-fold. When the mast cells were incubated with 10(-8), 10(-7) and 10(-6) M of amlexanox combined with 10(-7) M isoproterenol, the cAMP contents were synergistically increased 15-, 60- and 88-fold, respectively. 3-Isobutyl-1-methylxanthine (IBMX) at 10(-6)-10(-4) M increased the cAMP content 1.7-3.8-fold, and a combination of 10(-4) M IBMX and 10(-7) M isoproterenol synergistically increased the cAMP content 41-fold. A combination of amlexanox and IBMX synergistically increased the cAMP content 19-fold. The increase in cAMP content, when amlexanox and isoproterenol were combined, was transient; it peaked at 0.5 min after the drugs were administered, then decreased to 20-30% of the peak value about 2 min later. Pretreatment of mast cells with amlexanox reduced the effect of the combination of amlexanox and isoproterenol, indicating tachyphylaxis; pretreatment with IBMX had no such effect. The cAMP content of macrophages was also increased by amlexanox, but when combined with isoproterenol or PGE2, the effect was additive. Amlexanox inhibited cAMP phosphodiesterase in rat mast cells; its IC50 value was 1.4 X 10(-5) M, and its inhibitory activity was half that of IBMX.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In studies of the role of leukotrienes in inflammatory reactions, the induction of rat reversed passive Arthus pleurisy (a type III allergic reaction) was employed. Increases of exudate volume, vascular permeability, and migration of inflammatory cells in the pleural cavity were observed. The vascular permeability was enhanced biphasically during 0-30 min (early response) and during 3-6 h (late response) after induction of the pleurisy. The infiltration of inflammatory cells, mainly polymorphonuclear leukocytes, into the cavity increased and reached a maximum 6 h after the pleurisy was induced. Leukotriene B4 (LTB4), 5-monohydroxyeicosatetraenoic acid (5-HETE), and slow-reacting substance of anaphylaxis (SRS-A), consisting of LTC4, LTD4 and LTE4, were detected in the exudate by reversed-phase high-performance liquid chromatography during the early response. The contents of LTC4 reached a maximum 10 min after the challenge, followed by a rapid decrease within 1 h. The rise and decay of LTC4 correlated with the increase in vascular permeability during the early phase. AA-861, a 5-lipoxygenase inhibitor, given intrapleurally inhibited the increase in vascular permeability, cell migration, and generation of leukotrienes during the early phase of the pleurisy. These results indicate that products of the 5-lipoxygenase pathway, such as LTC4 and LTB4, may play an important role as chemical mediators in the inflammatory reaction.

Abstract
Amoxanox has potent antiallergic activity because it inhibits the release of chemical mediators such as histamine and leukotrienes. We studied the in vitro effect of amoxanox on arachidonic acid metabolism, including the lipoxygenase and cyclooxygenase pathways. Amoxanox inhibited calcium ionophore A23187-induced formation of 5-HETE, LTB4, SRS-A (LTC4, LTD4 and LTE4), and 12-HETE in rat peritoneal resident monocytes. These results indicate that amoxanox inhibits 5- and 12-lipoxygenases. The compound, however, did not affect the formation of TXB2 or 6-keto-PGF1 alpha in guinea pig lung fragments and PGE2 or PGF2 alpha in bovine seminal vesicles, suggesting that it did not inhibit cyclooxygenase. These results show that the antiallergic action of amoxanox is associated, at least in part, with the reduction of leukotrienes due to the inhibition of lipoxygenases.

Abstract
We studied the effects of amoxanox (AA-673) on allergic asthma and spasmogen-induced bronchoconstriction in guinea pigs and rats. Amoxanox given orally or parenterally inhibited allergic asthma mediated by IgE, IgG1, or heterologous IgG in guinea pigs and by IgE in rats. This compound also reduced leukotriene D4- and platelet-activating factor-induced bronchoconstriction in guinea pigs, strongly suggesting an antagonistic activity against slow reacting substance of anaphylaxis (SRS-A). Histamine- or acetylcholine-induced bronchoconstriction was not significantly affected by amoxanox. These antiasthmatic effects of amoxanox seem to be associated with an inhibition of the release of chemical mediators such as histamine and SRS-A and with an antagonism against SRS-A.

Abstract
Amoxanox inhibited immunologically stimulated and LTD4-induced bronchoconstriction in laboratory animals. Amoxanox, like DSCG, inhibited rat IgE-mediated PCA and histamine release from rat peritoneal mast cells, and suppressed immunologically stimulated or calcium ionophore A23187-induced SRS-A generation in rat peritoneal cavity and guinea pig lung fragments. This compound also reduced the contractile response of guinea pig lung parenchymal and ileal strips to LTD4, but did not significantly affect the response of the ileum to either histamine or acetylcholine. Therefore, the antiallergic action of amoxanox seems to be associated with inhibition of chemical mediator release and antagonistic activity on SRS-A.

Abstract
AA-861, a selective 5-lipoxygenase inhibitor, suppressed A23187-induced formations of 5-HETE and LTB4 in rat peritoneal macrophages. Immunologically-stimulated generation of SRS-A was also inhibited in guinea pig lung and rat peritoneal cavity. AA-861 had no effects on histamine release from rat mast cells or passive cutaneous anaphylaxis in rats. Essentially no antagonistic activity to LTD4 or histamine was observed. This compound exerted an obvious inhibition of allergic bronchoconstriction in guinea pigs and a moderate reduction of carrageenin-induced paw edema and pleurisy in rats. These findings suggest that SRS-A plays an important role in asthmatic and inflammatory reactions.
