BACKGROUND: A British randomised study of gemcitabine plus cisplatin (GC) combination showed promising results in biliary tract cancer (BTC) patients. In our study, we evaluated the efficacy and safety of this combination compared with gemcitabine alone (G) in Japanese BTC patients. METHODS: Overall, 84 advanced BTC patients were randomised to either cisplatin 25 mg m(-2) plus gemcitabine 1000 mg m(-2) on days 1, 8 of a 21-day cycle (GC-arm), or single-agent gemcitabine 1000 mg m(-2) on days 1, 8 and 15 of a 28-day cycle (G-arm). Treatments were repeated for at least 12 weeks until disease progression or unacceptable toxicity occurred, up to a maximum of 48 weeks. RESULTS: A total of 83 patients were included in the analysis. For the GC and G-arms, respectively, the 1-year survival rate was 39.0 vs 31.0%, median survival time 11.2 vs 7.7 months, median progression-free survival time 5.8 vs 3.7 months and overall response rate 19.5 vs 11.9%. The most common grade 3 or 4 toxicities (GC-arm/G-arm) were neutropenia (56.1%/38.1%), thrombocytopenia (39.0%/7.1%), leukopenia (29.3%/19.0%), haemoglobin decrease (36.6%/16.7%) and gamma-GTP increase (29.3%/35.7%). CONCLUSIONS: Gemcitabine plus cisplatin combination therapy was found to be effective and well tolerated, suggesting that it could also be a standard regimen for Japanese patients.

According to the amyloid cascade hypothesis, cerebral deposition of amyloid-β peptide (Aβ) is critical for Alzheimer's disease (AD) pathogenesis. Aβ generation is initiated when β-secretase (BACE1) cleaves the amyloid precursor protein. For more than a decade, BACE1 has been a prime target for designing drugs to prevent or treat AD. However, development of such agents has turned out to be extremely challenging, with major hurdles in cell penetration, oral bioavailability/metabolic clearance, and brain access. Using a fragment-based chemistry strategy, we have generated LY2811376 [(S)-4-(2,4-difluoro-5-pyrimidin-5-yl-phenyl)-4-methyl-5,6-dihydro-4H-[1,3]thiazin-2-ylamine], the first orally available non-peptidic BACE1 inhibitor that produces profound Aβ-lowering effects in animals. The biomarker changes obtained in preclinical animal models translate into man at doses of LY2811376 that were safe and well tolerated in healthy volunteers. Prominent and long-lasting Aβ reductions in lumbar CSF were measured after oral dosing of 30 or 90 mg of LY2811376. This represents the first translation of BACE1-driven biomarker changes in CNS from preclinical animal models to man. Because of toxicology findings identified in longer-term preclinical studies, this compound is no longer progressing in clinical development. However, BACE1 remains a viable target because the adverse effects reported here were recapitulated in LY2811376-treated BACE1 KO mice and thus are unrelated to BACE1 inhibition. The magnitude and duration of central Aβ reduction obtainable with BACE1 inhibition positions this protease as a tractable small-molecule target through which to test the amyloid hypothesis in man.

OBJECTIVE: Baricitinib is an oral, once-daily selective Janus kinase (JAK1/JAK2) inhibitor for adults with moderately to severely active rheumatoid arthritis (RA). We evaluated baricitinib's safety profile through 288 weeks (up to September 1, 2016) with an integrated database [8 phase III/II/Ib trials, 1 longterm extension (LTE)]. METHODS: The "all-bari-RA" group included patients who received any baricitinib dose. Placebo comparison was based on the 6 studies with 4 mg and placebo up to Week 24 ("placebo-4 mg" dataset). Dose response assessment was based on 4 studies with 2 mg and 4 mg including LTE data ("2 mg-4 mg-extended"). The uncommon events description used the non-controlled all-bari-RA. RESULTS: There were 3492 patients who received baricitinib for 6637 total patient-years (PY) of exposure (median 2.1 yrs, maximum 5.5 yrs). No differences in rates of death, adverse events leading to drug discontinuation, malignancies, major adverse cardiovascular event (MACE), or serious infections were seen for 4 mg versus placebo or for 4 mg versus 2 mg. Infections including herpes zoster were significantly more frequent for 4 mg versus placebo. Deep vein thrombosis/pulmonary embolism were reported with 4 mg but not placebo [all-bari-RA incidence rate (IR) 0.5/100 PY]; the IR did not differ between doses (0.5 vs 0.6/100 PY, 2 mg vs 4 mg, respectively) or compared to published RA rates. All-bari-RA had 6 cases of lymphoma (IR 0.09/100 PY), 3 gastrointestinal perforations (0.05/100 PY), 10 cases of tuberculosis (all in endemic areas; 0.15/100 PY), and 22 all-cause deaths (0.33/100 PY). IR for malignancies (0.8/100 PY) and MACE (0.5/100 PY) were low and did not increase with prolonged exposure. CONCLUSION: In this integrated analysis of patients with moderate to severe active RA with exposure up to 5.5 years, baricitinib has an acceptable safety profile in the context of demonstrated efficacy. Trial registration numbers: NCT01185353, NCT00902486, NCT01469013, NCT01710358, NCT01721044, NCT01721057, NCT01711359, and NCT01885078 at clinicaltrials.gov.

OBJECTIVE: Mealtime insulin is commonly added to manage hyperglycemia in type 2 diabetes when basal insulin is insufficient. However, this complex regimen is associated with weight gain and hypoglycemia. This study compared the efficacy and safety of exenatide twice daily or mealtime insulin lispro in patients inadequately controlled by insulin glargine and metformin despite up-titration. RESEARCH DESIGN AND METHODS: In this 30-week, open-label, multicenter, randomized, noninferiority trial with 12 weeks prior insulin optimization, 627 patients with insufficient postoptimization glycated hemoglobin A1c (HbA1c) were randomized to exenatide (10-20 µg/day) or thrice-daily mealtime lispro titrated to premeal glucose of 5.6-6.0 mmol/L, both added to insulin glargine (mean 61 units/day at randomization) and metformin (mean 2,000 mg/day). RESULTS: Randomization HbA1c and fasting glucose (FG) were 8.3% (67 mmol/mol) and 7.1 mmol/L for exenatide and 8.2% (66 mmol/mol) and 7.1 mmol/L for lispro. At 30 weeks postrandomization, mean HbA1c changes were noninferior for exenatide compared with lispro (-1.13 and -1.10%, respectively); treatment differences were -0.04 (95% CI -0.18, 0.11) in per-protocol (n = 510) and -0.03 (95% CI -0.16, 0.11) in intent-to-treat (n = 627) populations. FG was lower with exenatide than lispro (6.5 vs. 7.2 mmol/L; P = 0.002). Weight decreased with exenatide and increased with lispro (-2.5 vs. +2.1 kg; P < 0.001). More patients reported treatment satisfaction and better quality of life with exenatide than lispro, although a larger proportion of patients with exenatide experienced treatment-emergent adverse events. Exenatide resulted in fewer nonnocturnal hypoglycemic episodes but more gastrointestinal adverse events than lispro. CONCLUSIONS: Adding exenatide to titrated glargine with metformin resulted in similar glycemic control as adding lispro and was well tolerated. These findings support exenatide as a noninsulin addition for patients failing basal insulin.

Psoriasis, a chronic, immune-mediated skin disease characterized by red, scaly plaques, affects approximately 0.3% of the population in Japan. The aim of this open-label study was to evaluate the long-term efficacy and safety of ixekizumab, a humanized, anti-interleukin-17A monoclonal antibody, in Japanese patients with plaque psoriasis (n = 78, including 11 psoriatic arthritis), erythrodermic psoriasis (n = 8) and generalized pustular psoriasis (n = 5). Ixekizumab was administrated s.c. at baseline (week 0, 160 mg), from weeks 2 to 12 (80 mg every 2 weeks), and from weeks 16 to 52 (80 mg every 4 weeks). At week 52, 92.3% of patients with plaque psoriasis achieved Psoriasis Area and Severity Index (PASI) 75, 80.8% achieved PASI 90, 48.7% achieved PASI 100, and 52.6% had remission of plaques (by static Physician Global Assessment, sPGA [0]). Difficult to treat areas of psoriasis (nail or scalp) also responded to ixekizumab. All patients with psoriatic arthritis who were assessed (5/5) achieved an American College of Rheumatology 20 response. Most patients with erythrodermic psoriasis or generalized pustular psoriasis responded to ixekizumab and the clinical outcome was maintained over 52 weeks (75% and 60% of patients achieved sPGA [0, 1] at week 52, respectively). Mostly mild or moderate treatment-emergent adverse events were reported by 79 of 91 patients; the most common were nasopharyngitis, eczema, seborrheic dermatitis, urticaria and injection site reactions. In conclusion, 52-week ixekizumab treatment was efficacious and well tolerated in Japanese patients with plaque psoriasis. Efficacy was also observed in patients with erythrodermic psoriasis, generalized pustular psoriasis and psoriatic arthritis.

BACKGROUND: The objective of this review was to determine the unmet needs for migraine in East Asian adults and children. METHODS: We searched MEDLINE and EMBASE (January 1, 1988 to January 14, 2019). Studies reporting the prevalence, humanistic and economic burden, and clinical management of migraine in China (including Hong Kong and Taiwan), Japan, and South Korea were included. Studies conducted before 1988 (before the International Headache Society [IHS] first edition of the International Classification of Headache Disorders) were not included. RESULTS: We retrieved 1337 publications and 41 met the inclusion criteria (28 from China, 7 from Japan, and 6 from South Korea). The 1-year prevalence of migraine (IHS criteria) among adults ranged from 6.0% to 14.3%. Peak prevalence ranged from 11% to 20% for women and 3% to 8% for men (30- to 49-year-olds). For children, prevalence of migraine increased with age. Information on the economic burden and clinical management of migraine was limited, particularly for children. When reported, migraine was significantly associated with high levels of disability and negative effects on quality of life. Studies suggested low levels of disease awareness/diagnosis within each country. Of individuals with migraine from China, 52.9% to 68.6% had consulted a physician previously, 37.2% to 52.7% diagnosed with headache had not been diagnosed with migraine previously, and 13.5% to 18% had been diagnosed with migraine previously. Of individuals with migraine from Japan, 59.4% to 71.8% had never consulted a physician previously, 1.3% to 7.3% regularly consulted physicians for their headache, and only 11.6% of individuals with migraine were aware that they had migraine. In addition, studies suggested that over-the-counter medication use was high and prescription medication use was low in each country. CONCLUSIONS: This review suggests that there are unmet needs for migraine in terms of sufficient and appropriate diagnosis, and better management and therapies for treatment of migraine in East Asia. The findings are limited by a lack of recent information and significant gaps in the literature. More recent, population-based studies assessing disease burden and clinical management of migraine are needed to confirm unmet needs for migraine across East Asia.

BACKGROUND: This study assessed how family caregivers for patients with Alzheimer's disease (AD) or dementia in Japan differed from non-caregivers in characteristics and health outcomes (i.e., comorbidities, health-related quality of life [HRQoL], productivity, and resource use). Caregivers were hypothesized to experience significantly poorer outcomes than non-caregivers. METHODS: Data were combined from the 2012 and 2013 National Health and Wellness Survey in Japan (n = 60000). Caregivers for adult relatives with AD or dementia were compared with non-caregivers on: comorbidities (including Patient Health Questionnaire (PHQ-9) cutoff scores suggesting presence/absence of major depressive disorder (MDD)), Work Productivity and Activity Impairment (WPAI), SF-36v2-based HRQoL, and healthcare resource utilization. Sociodemographic characteristics, health characteristics and behaviors, and Charlson comorbidity index (CCI) scores were compared across groups. Propensity matching, based on scores generated from a logistic regression predicting caregiving, was used to match caregivers with non-caregivers with similar likelihood of being caregivers. Bivariate comparisons across matched groups served to estimate outcomes differences due to caregiving. RESULTS: Among 55060 respondents, compared with non-caregivers (n = 53758), caregivers (n = 1302) were older (52.6 vs. 47.5 years), more frequently female (53 % vs. 49 %), married/partnered, frequent alcohol drinkers, current smokers, exercisers, and not employed, and they averaged higher CCI scores (0.37 vs. 0.14), all p < 0.05. Propensity scores incorporated sex, age, body mass index (BMI), exercise, alcohol, smoking, marital status, CCI, insured status, education, employment, income, and children in household. A greedy matching algorithm produced 1297 exact matches, excluding 5 non-matched caregivers. Health utilities scores were significantly lower among caregivers (0.724) vs. non-caregivers (0.764), as were SF-36v2 Physical and Mental Component Summary scores. Caregivers vs. non-caregivers had significantly higher absenteeism, presenteeism-related impairment, overall work impairment (25.8 % vs. 20.4 %, respectively), and activity impairment (25.4 % vs. 21.8 %), more emergency room and traditional provider visits (7.70 vs. 5.35) in the past six months, and more frequent MDD (14 % vs. 9 %), depression, insomnia, anxiety, and pain. CONCLUSIONS: Those providing care for patients with AD or dementia in Japan experienced significantly poorer HRQoL and greater comorbid risk, productivity impairment, and resource use. These findings inform the need for greater support for caregivers and their patients.

In recent years there has been rapid growth in diabetes in Japan which now is one of the nations most affected by the worldwide diabetes epidemic. Diabetes has been identified as a healthcare priority by the Ministry of Health, Labour and Welfare (MHLW). Type 1 diabetes is rare in Japan, and type 2 diabetes predominates in both adults and children. The growth in diabetes is due to increases in the number of people with type 2 diabetes associated with increased longevity and lifestyle changes. Approximately 13.5% of the Japanese population now has either type 2 diabetes or impaired glucose tolerance. This high prevalence of type 2 diabetes is associated with a significant economic burden, with diabetes accounting for up to 6% of the total healthcare budget. The costs of diabetes are increased in patients with co-morbidities such as hypertension and hyperlipidaemia and in patients who develop complications, of which retinopathy has the highest cost. Costs increase with increasing number of complications. Current guidelines from the Japan Diabetes Society (JDS) recommend a target HbA(1c) of 6.5% for glycaemic control. This is achieved in approximately one third of patients with type 2 diabetes, and Japanese patients typically have lower HbA(1c) than patients in Western countries (e.g. US, UK). Japanese patients with type 2 diabetes have better adherence with diet and exercise recommendations than their peers in Western countries. Sulfonylureas have been the most widely prescribed first-line treatment for type 2 diabetes, although there is increasing use of combination therapy and of insulin.

Gemcitabine is a deoxycytidine analogue that has a broad spectrum of antitumour activity in many solid tumours including pancreatic cancer. We have recently carried out a pharmacogenomic study in cancer patients treated with gemcitabine, and found that one genetic polymorphism of an enzyme involved in gemcitabine metabolism can cause interindividual variations in the pharmacokinetics and toxicity of this agent. In this paper, we review recent genetic studies of gemcitabine, and discuss the possibility of individualised cancer chemotherapy based on a pharmacogenomic approach.

The treatment and management of chronic pain is a major challenge for clinicians. Chronic pain is often underdiagnosed and undertreated, and there is a lack of awareness of the pathophysiologic mechanisms that contribute to chronic pain. Chronic pain involves peripheral and central sensitization, as well as the alteration of the pain modulatory pathways. Imbalance between the descending facilitatory systems and the descending inhibitory systems is believed to be involved in chronic pain in pathological conditions. A pharmacological treatment that could restore the balance between these 2 pathways by diminishing the descending facilitatory pain pathways and enhancing the descending inhibitory pain pathways would be a valuable therapeutic option for patients with chronic pain. Due to the lack of evidence for pharmacological options that act on descending facilitation pathways, in this review we summarize the role of the descending inhibitory pain pathways in pain perception. This review will focus primarily on monoaminergic descending inhibitory pain pathways and their contribution to the mechanism of chronic pain and several pharmacological treatment options that enhance these pathways to reduce chronic pain. We describe anatomical structures and neurotransmitters of the descending inhibitory pain pathways that are activated in response to nociceptive pain and altered in response to sustained and persistent pain which leads to chronic pain in various pathological conditions.

Abstract The mechanisms controlling CD4 + T cell switching from an effector to an anti-inflammatory (IL-10 + ) phenotype play an important role in the persistence of chronic inflammatory diseases. Here, we identify the cholesterol biosynthesis pathway as a key regulator of this process. Pathway analysis of cultured cytokine-producing human T cells reveals a significant association between IL-10 and cholesterol metabolism gene expression. Inhibition of the cholesterol biosynthesis pathway with atorvastatin or 25-hydroxycholesterol during switching from IFNγ + to IL-10 + shows a specific block in immune resolution, defined as a significant decrease in IL-10 expression. Mechanistically, the master transcriptional regulator of IL10 in T cells, c-Maf, is significantly decreased by physiological levels of 25-hydroxycholesterol. Strikingly, progression to rheumatoid arthritis is associated with altered expression of cholesterol biosynthesis genes in synovial biopsies of predisposed individuals. Our data reveal a link between sterol metabolism and the regulation of the anti-inflammatory response in human CD4 + T cells.

BACKGROUND: Ixekizumab, an anti-IL-17A monoclonal antibody, demonstrated a high level of efficacy in moderate-to-severe plaque psoriasis (PP) patients. OBJECTIVE: To evaluate the efficacy and safety of open-label ixekizumab in Japanese patients with moderate-to-severe PP, erythrodermic psoriasis (EP) and generalized pustular psoriasis (GPP). METHODS: Patients received 160-mg subcutaneous ixekizumab injection at Week 0, 80-mg every 2 weeks through Week 12 and 80-mg every 4 weeks through Week 24. Efficacy and safety are reported through 24 weeks; additional safety data are available for some patients. RESULTS: A total of 78 patients with PP, 8 with EP and 5 with GPP enrolled. In PP patients, PASI75 and PASI90 response rates were 98.7% (77/78) and 83.3% (65/78) at Week 12 respectively. In EP patients, PASI75 and PASI90 were 100.0% (8/8) and 62.5% (5/8) and in GPP patients were 80.0% (4/5) and 60.0% (3/5). Overall, 84.0% (76/91) had a treatment-emergent AE through ≥24 weeks. There were no serious AEs, deaths, cases of tuberculosis or invasive fungal infections. LIMITATIONS: No control group and small sample sizes, especially for EP and GPP. CONCLUSION: By Week 12, nearly all patients with PP, EP and GPP achieved PASI75. The safety profile was consistent with reported results and no unexpected safety signals were observed.

BACKGROUND: Atypical antipsychotics are widely used in bipolar mania. However, the efficacy of atypical antipsychotics in bipolar depression has not been comprehensively explored. AIMS: To evaluate olanzapine monotherapy in patients with bipolar depression. METHOD: Patients with bipolar depression received olanzapine (5-20 mg/day, n = 343) or placebo (n = 171) for 6 weeks. The primary outcome was change from baseline to end-point in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Secondary outcomes included: Clinical Global Impression - Bipolar Version (CGI-BP) scale, 17-item Hamilton Rating Scale for Depression (HRSD-17) and Young Mania Rating Scale (YMRS) scores, and the rate of response (≥50% reduction in MADRS at end-point), recovery (MADRS ≤12 for ≥4 weeks plus treatment completion) and remission (MADRS ≤8). The trial was registered with ClinicalTrials.gov (NCT00510146). RESULTS: Olanzapine demonstrated: significantly greater (P<0.04) improvements on MADRS (least-squares mean change -13.82 v. -11.67), HRSD-17 and YMRS total scores and all CGI-BP subscale scores v. placebo; significantly (P≤0.05) more response and remission, but not recovery; significantly (P<0.01) greater mean increases in weight, fasting cholesterol and triglycerides; and significantly more (P<0.001) patients gained ≥7% body weight. CONCLUSIONS: Olanzapine monotherapy appears to be efficacious in bipolar depression. Additional long-term studies are warranted to confirm these results. Safety findings were consistent with the known safety profile of olanzapine.

OBJECTIVE: To evaluate efficacy and safety, baricitinib [Janus kinase (JAK) 1/JAK2 inhibitor] was compared with placebo in Japanese patients with active rheumatoid arthritis (RA) despite background treatment with methotrexate (MTX). METHODS: This was a phase IIB, double-blind, randomized, placebo-controlled study (clinicaltrials.gov: NCT01469013). Patients had moderate to severe active adult-onset RA despite stable treatment with MTX. Patients (n = 145) were randomized in a 2:1:1:1:1 ratio to placebo or 1 mg, 2 mg, 4 mg, or 8 mg oral baricitinib daily for 12 weeks. The primary analysis compared the combined 4/8-mg dose groups with placebo for the American College of Rheumatology (ACR) 20 response rate at 12 weeks. Other outcomes included additional measures of disease activity, physical function, laboratory abnormalities, and adverse events. RESULTS: A significantly higher proportion of patients in the combined 4/8-mg baricitinib group (37/48, 77%) compared with the placebo group (15/49, 31%) had at least an ACR20 response after 12 weeks of treatment (p < 0.001). Significant improvements in disease activity, remission, and physical function were observed as early as Week 2 of treatment with baricitinib, particularly with daily doses of ≥ 4 mg. Only 1 patient receiving baricitinib discontinued because of an adverse event. Adverse event rates with baricitinib doses ≤ 4 mg daily were similar to placebo, but there was a higher incidence of adverse events and laboratory abnormalities in the 8-mg group. CONCLUSION: In this phase II study, baricitinib was well tolerated and rapidly improved the signs, symptoms, and physical function of Japanese patients with active RA, supporting continued development of baricitinib (clinicaltrials.gov NCT01469013).

PURPOSE: The objective of this study was to evaluate the efficacy and safety of two doses of pemetrexed supplemented with folic acid and vitamin B(12) in pretreated Japanese patients with advanced non-small cell lung cancer (NSCLC). EXPERIMENTAL DESIGN: Patients with an Eastern Cooperative Oncology Group performance status 0 to 2, stage III or IV, and who received previously one or two chemotherapy regimens were randomized to receive 500 mg/m(2) pemetrexed (P500) or 1,000 mg/m(2) pemetrexed (P1000) on day 1 every 3 weeks. The primary endpoint was response rate. RESULTS: Of the 216 patients evaluable for efficacy (108 in each arm), response rates were 18.5% (90% confidence interval, 12.6-25.8%) and 14.8% (90% confidence interval, 9.5-21.6%), median survival times were 16.0 and 12.6 months, 1-year survival rates were 59.2% and 53.7%, and median progression-free survival were 3.0 and 2.5 months for the P500 and P1000, respectively. Cox multiple regression analysis indicated that pemetrexed dose was not a significant prognostic factor. Drug-related toxicity was generally tolerable for both doses; however, the safety profile of P500 showed generally milder toxicity. Main adverse drug reactions of severity grade 3 or 4 were neutrophil count decreased (20.2%) and alanine aminotransferase (glutamine pyruvic transaminase) increased (15.8%) in P500 and neutrophil count decreased (24.3%), WBC count decreased (20.7%), and lymphocyte count decreased (18.0%) in P1000. One drug-related death from interstitial lung disease occurred in the P500. CONCLUSION: P500 and P1000 are similarly active with promising efficacy and acceptable safety outcomes in pretreated patients with NSCLC. These results support the use of P500 as a second- and third-line treatment of NSCLC.

OBJECTIVES: Ramucirumab plus docetaxel prolongs survival in patients with non-small cell lung cancer (NSCLC) with disease progression after platinum-based therapy. This phase II, double-blind, randomized, placebo-controlled study assessed efficacy and safety of second-line ramucirumab-docetaxel in Japanese patients with NSCLC. MATERIALS AND METHODS: Patients with NSCLC with progression after platinum-based therapy (28 Japanese sites; 19 December, 2012 to 22 May, 2015) were randomized (computer-generated sequence) to ramucirumab 10mg/kg or placebo, followed by docetaxel 60mg/m(2) (Day 1, 21-day cycle). Prior epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) monotherapy was prohibited in the primary population, but EGFR mutation-positive NSCLC patients who were treated with EGFR-TKI were enrolled as a separate exploratory population. Primary endpoint was progression-free survival (PFS); secondary outcomes included overall survival, tumor response rates, and safety. Investigator tumor assessments were used for the efficacy endpoints. RESULTS: In the primary population (N=160 randomized, n=157 treated), median (95% CI) PFS was longer with ramucirumab-docetaxel (5.22 [3.52-6.97] months; n=76) than with placebo-docetaxel (4.21 [2.83-5.62] months; n=81); hazard ratio 0.83 (95% CI 0.59-1.16). Median (95% CI) overall survival was 15.15 (12.45-26.55) months with ramucirumab-docetaxel and 14.65 (11.93-24.44) months with placebo-docetaxel (hazard ratio [95% CI] 0.86 [0.56-1.32]). Objective response rate (28.9% vs 18.5%) and disease control rate (78.9% vs 70.4%) were numerically greater with ramucirumab-docetaxel than with placebo-docetaxel. Incidence and severity of most adverse events were similar, but febrile neutropenia was more common with ramucirumab-docetaxel (34.2%) than with placebo-docetaxel (19.8%). CONCLUSION: Second-line ramucirumab-docetaxel improved PFS similar to that seen in the REVEL trial with a manageable safety profile in Japanese patients with NSCLC.

Abstract Purpose: Investigate the safety and efficacy of LY3415244, a TIM-3/PD-L1 bispecific antibody that blocks TIM-3 and PD-L1 in patients with advanced solid tumors. Patients and Methods: A phase I, multicenter, open-label study was conducted in patients with advanced solid tumors. Patients were dosed every 2 weeks intravenously with flat doses of LY3415244 escalating from 3 to 70 mg. The primary endpoints were safety, tolerability, and identification of the recommended phase II dose. Results: Between November 2018 and October 2019, 12 patients were enrolled into four cohorts and received at least one dose of LY3415244. Two patients (16.7%) developed clinically significant anaphylactic infusion-related reactions and all patients developed treatment-emergent antidrug antibodies (TE-ADA). ADA titers were sometimes very high and negatively impacted soluble TIM-3 target engagement in most patients. ADA epitope specificity was against both TIM-3 and PD-L1 arms of the bispecific antibody; most TE-ADAs initially targeted the TIM-3 arm after the first dose. Preexisting ADAs against LY3415244 were also detected in normal (unexposed) human serum samples. One patient with PD-1 refractory non–small cell lung cancer had a near partial response (−29.6%). Conclusions: This TIM-3 and PD-L1 bispecific format was associated with unexpected immunogenicity targeting both arms of the bispecific antibody, resulting in early study termination. Epitope specificity analysis revealed an initial response toward the TIM-3 arm and presence of preexisting ADAs to the bispecific molecule in the general population. This experience emphasizes the importance of thorough analyses for preexisting ADAs as part of immunogenicity risk assessment of novel antibodies.

OBJECTIVES: To identify, describe and summarize evidence on residual symptoms and disease burdens in rheumatoid arthritis (RA) patients qualified as being in remission or low disease activity (LDA). METHODS: A systematic literature review (SLR) was conducted according to Cochrane collaboration guidelines. The population of interest was adult patients with RA in remission or LDA. The reported outcomes of interest were any symptoms or burdens. RESULTS: Fifty-one publications were identified through an eDatabase search. Together with 17 articles found through other sources, 68 were included for full text review. The most commonly reported residual symptoms were pain (number of studies = 25), fatigue (n = 21) and morning stiffness (n = 5). Reported disease burdens included mental health (n = 15), sleep disturbances (n = 7) and work productivity (n = 5), impairment in quality of life (n = 21), and functional disability (n = 34). Substantial residual symptoms and disease burdens were found to be present in patients in remission or LDA. CONCLUSION: This is the first SLR to investigate residual symptoms and disease burdens in RA patients in remission or LDA. The results indicate that despite achieving conventional clinical targets, the disease continues to affect patients, suggesting the existence of unmet need under the current treatment paradigm.

BACKGROUND: Donanemab (LY3002813) is an IgG1 antibody directed at an N‑terminal pyroglutamate of amyloid beta epitope that is present only in brain amyloid plaques. OBJECTIVES: To assess effects of donanemab on brain amyloid plaque load after single and multiple intravenous doses, as well as pharmacokinetics, safety/tolerability, and immunogenicity. DESIGN: Phase 1b, investigator- and patient-blind, randomized, placebo-controlled study. SETTING: Patients recruited at clinical research sites in the United States and Japan. PARTICIPANTS: 61 amyloid plaque-positive patients with mild cognitive impairment due to Alzheimer's disease and mild-to-moderate Alzheimer's disease dementia. INTERVENTION: Six cohorts were dosed with donanemab: single dose 10-, 20- or 40- mg/kg (N = 18), multiple doses of 10-mg/kg every 2 weeks for 24 weeks (N = 10), and 10- or 20-mg/kg every 4 weeks for 72 weeks (N=18) or placebo (N = 15). MEASUREMENTS: Brain amyloid plaque load, using florbetapir positron emission tomography, was assessed up to 72 weeks. Safety was evaluated by occurrence of adverse events, magnetic resonance imaging, electrocardiogram, vital signs, laboratory testing, neurological monitoring, and immunogenicity. RESULTS: Treatment with donanemab resulted in rapid reduction of amyloid, even after a single dose. By 24 weeks, amyloid positron emission tomography mean changes from baseline for single donanemab doses in Centiloids were: -16.5 (standard error 11.22) 10-mg/kg intravenous; 40.0 (standard error 11.23) 20 mg/kg intravenous; and -49.6 (standard error 15.10) 40-mg/kg intravenous. Mean reduction of amyloid plaque in multiple dose cohorts by 24 weeks in Centiloids were: 55.8 (standard error 9.51) 10-mg/kg every 2 weeks; -50.2 (standard error 10.54) 10-mg/kg every 4 weeks; and -58.4 (standard error 9.66) 20-mg/kg every 4 weeks. Amyloid on average remained below baseline levels up to 72 weeks after a single dose of donanemab. Repeated dosing resulted in continued florbetapir positron emission tomography reductions over time compared to single dosing with 6 out of 28 patients attaining complete amyloid clearance within 24 weeks. Within these, 5 out of 10 patients in the 20 mg/kg every 4 weeks cohort attained complete amyloid clearance within 36 weeks. When dosing with donanemab was stopped after 24 weeks of repeat dosing in the 10 mg every 2 weeks cohort, florbetapir positron emission tomography reductions were sustained up to 72 weeks. For the single dose cohorts on day 1, dose proportional increases in donanemab pharmacokinetics were observed from 10 to 40 mg/kg. Dose proportional increases in pharmacokinetics were also observed at steady state with the multiple dose cohorts. Donanemab clearance was comparable across the dose levels. Mean donanemab elimination-half-life following 20 mg/kg single dose was 9.3 days with range of 5.6 to 16.2 days. Greater than 90% of patients had positive treatment-emergent antidrug antibodies with donanemab. However, overall, the treatment-emergent antidrug antibodies did not have a significant impact on pharmacokinetics. Donanemab was generally well tolerated. Amongst the 46 participants treated with donanemab, the following amyloid-related imaging abnormalities, common to the drug class, were observed: 12 vasogenic cerebral edema events (12 [19.7%] patients), 10 cerebral microhemorrhage events (6 [13.0%] patients), and 2 superficial siderosis events (2 [4.3%] patients). CONCLUSIONS: Single and multiple doses of donanemab demonstrated a rapid, robust, and sustained reduction up to 72 weeks in brain amyloid plaque despite treatment-emergent antidrug antibodies detected in most patients. Amyloid-related imaging abnormalities were the most common treatment-emergent event.

INTRODUCTION: The ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE study in Japan (OVERCOME [Japan]) assessed the impact and burden of migraine in Japan. METHODS: OVERCOME (Japan) was a cross-sectional, observational, population-based web survey of Japanese people with migraine conducted between July and September 2020. The burden and impact of migraine were assessed using the Migraine Disability Assessment (MIDAS), Migraine-Specific Quality-of-Life Questionnaire (MSQ), Migraine Interictal Burden Scale (MIBS-4), and Work Productivity and Activity Impairment-Migraine scale. Results were stratified by average number of monthly headache days (0-3, 4-7, 8-14, ≥ 15). RESULTS: In total, 17,071 Japanese people with migraine completed the survey. Of these, 14,033 (82.2%) met International Classification of Headache Disorders, 3rd edition criteria for migraine and 9667 (56.6%) reported a physician diagnosis of migraine. Overall, 20.7% of respondents experienced moderate-to-severe disability (MIDAS). Moderate-to-severe interictal burden (MIBS-4) was experienced by 41.5% of respondents. MSQ scores in all domains were lowest in respondents with the most frequent headaches (≥ 15 monthly headache days) and highest in those with the lowest frequency headaches (≤ 3 monthly headache days), indicating poorer quality of life in those with more frequent headaches. Work time missed due to migraine (absenteeism) increased with increasing headache frequency, from 3.8 to 6.2%; presenteeism affected 29.8-49.9% of work time. Although migraine burden was greatest in people with the most frequent headaches, those with the lowest headache frequency still experienced substantial disability, interictal burden, and impacts on productivity and quality of life. There was also substantial unmet need for migraine care: 36.5% of respondents had ever hesitated to seek medical care for their headaches, and 89.8% had never used preventive medication. CONCLUSION: In Japan, the burden of migraine and barriers to migraine care are substantial. Improving patient awareness and healthcare provider vigilance may help improve patient outcomes.
