Lymphatic anomalies (LAs) include several disorders in which abnormal lymphatic tissue invades the neck, chest, and various organs. Progressive cases may result in lethal outcomes and have proven difficult to treat. Sirolimus is showing promising results in the management of vascular anomalies. We examined the efficacy and safety of sirolimus treatment in patients with progressive LAs. All patients with LAs treated with sirolimus from May 2015 to September 2018 were included. They received oral sirolimus once a day and the dose was adjusted so that the trough concentration remained within 5–15 ng/mL. We prospectively reviewed the response to drugs (the response rate of radiological volumetric change of the target lesion), severity scores, reported quality of life (QOL), and adverse effects at 6 months after administration. Twenty patients (five with cystic lymphatic malformation (LM), three with kaposiform lymphangiomatosis, three with generalized lymphatic anomaly, six with Gorham-Stout disease, and three with central conducting lymphatic anomaly) were treated with sirolimus at our institution. Fifty percent of patients (10/20) demonstrated a partial response by a radiological examination and a significant improvement in disease severity and QOL scores (P = 0.0020 and P = 0.0117, respectively). Ten patients who had no reduction in lesion size (stable disease group) showed no significant improvement in disease severity and QOL scores. Eighty percent of patients (16/20) had side effects, such as stomatitis, infection, and hyperlipidemia. Sirolimus impacts the reduction of the lymphatic tissue volume of LMs and could lead to improvement in clinical symptoms and QOL. UMIN Clinical Trials Registry, UMIN000016580 .

Lymphatic anomalies (LAs) refer to a group of diseases involving systemic dysplasia of lymphatic vessels. These lesions are classified as cystic lymphatic malformation (macrocystic, microcystic or mixed), generalized lymphatic anomaly, and Gorham-Stout disease. LAs occur mainly in childhood, and present with various symptoms including chronic airway problems, recurrent infection, and organ disorders. Individuals with LAs often experience progressively worsening symptoms with a deteriorating quality of life. Although limited treatment options are available, their efficacy has not been validated in prospective clinical trials, and are usually based on case reports. Thus, there are no validated standards of care for these patients because of the lack of prospective clinical trials. This open-label, single-arm, multicenter, prospective study will assess the efficacy and safety of a mammalian target of the rapamycin inhibitor sirolimus in the treatment of intractable LAs. Participants will receive oral sirolimus once a day for 52 weeks. The dose is adjusted so that the nadir concentration remains within 5-15 ng/ml. The primary endpoint is the response rate of radiological volumetric change of the target lesion confirmed by central review at 52 weeks after treatment. The secondary endpoints are the response rates at 12 and 24 weeks, respiratory function, pleural effusion, ascites, blood coagulation parameters, bleeding, pain, quality of life, activities of daily living, adverse events, side effects, laboratory examinations, vital signs, and pharmacokinetic data. This is among the first multicenter studies to evaluate sirolimus treatment for intractable LAs, and few studies to date have focused on the standard assessment of the efficacy for LAs treatment. Our protocol uses novel, uncomplicated methods for radiological assessment, with reference to the results of our previous retrospective survey and historical control data from the literature. We propose a multicenter study to investigate the efficacy and safety of sirolimus for intractable LAs (SILA study; trial registration UMIN000028905). Our results will provide pivotal data to support the approval of sirolimus for the treatment of intractable LAs.

In Japan, docetaxel, a cytotoxic monotherapy, is the standard drug administered to older patients with advanced non-small-cell lung cancer (NSCLC). Carboplatin plus nab-paclitaxel has shown a high objective response rate in patients with squamous histology and was suggested to improve overall survival in patients aged 70 years and older. The CAPITAL trial aimed to assess the safety and efficacy of carboplatin plus nab-paclitaxel versus docetaxel as first-line therapy for patients aged 70 years and older with advanced squamous NSCLC. This multicentre, open-label, randomised, phase 3 trial was carried out at 92 medical institutions in Japan. Eligible patients were aged 70 years and older, had advanced squamous NSCLC with no previous systemic chemotherapy, and had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. Using an electronic data capture system, patients were randomly assigned (1:1) to intravenous carboplatin (area under the concentration-time curve of 6 mg/mL per min for 30 min) on day 1 of a 21-day cycle and intravenous nab-paclitaxel (100 mg/m² for 60 min) on days 1, 8, and 15 every 3 weeks or intravenous docetaxel (60 mg/m² for 60 min) on day 1 every 3 weeks. Randomisation was computer-generated per participant and stratified by ECOG performance status, clinical stage, sex, age, and institution. The primary endpoint was overall survival, measured in the full analysis set and defined as the time from registration to the date of death due to any cause. Safety was assessed in all patients who received at least one dose of the trial treatment. This trial is registered with the UMIN Clinical Trials Registry, UMIN000019843, and the Japan Registry of Clinical Trials, jRCTs041180110. After the planned interim analysis in Aug 3, 2020, the independent data monitoring committee recommended that the trial be stopped early. This report represents the final analysis. Between Feb 24, 2016, and Aug 11, 2020, 196 patients were enrolled and were randomly assigned to the carboplatin plus nab-paclitaxel group (n=98) or the docetaxel group (n=98). Of these patients, four (carboplatin plus nab-paclitaxel group, n=3; docetaxel group, n=1) did not receive any treatment and two patients in the docetaxel group were excluded from the full analysis set. Median overall survival in the full analysis set was 16·9 months (95% CI 12·6-25·4) in the carboplatin plus nab-paclitaxel group and 10·9 months (8·5-12·4) in the docetaxel group (hazard ratio 0·52 [90% CI 0·38-0·70]; p=0·0003). Grade 3-4 adverse events occurred in 79 (83%) patients in the carboplatin plus nab-paclitaxel group and 77 (79%) patients in the docetaxel group (p=0·63). The most common grade 3-4 adverse events in the carboplatin plus nab-paclitaxel group and the docetaxel group were leukopenia (44 [46%] vs 55 [57%]; p=0·20), neutropenia (60 [63%] vs 75 [77%]; p=0·046), febrile neutropenia (nine [10%] vs 19 [20%]; p=0·073), and anaemia (37 [39%] vs two [2%]; p<0·0001). Serious treatment-related adverse events of all grades occurred in 13 (14%) patients in the carboplatin plus nab-paclitaxel group and 11 (11%) patients in the docetaxel group. Treatment-related deaths occurred in two (2%; respiratory failure n=1, visceral arterial ischaemia n=1) patients in the carboplatin plus nab-paclitaxel group and one (1%; sepsis) patient in the docetaxel group. Our study showed that overall survival was longer with carboplatin plus nab-paclitaxel than with docetaxel, suggesting that carboplatin plus nab-paclitaxel can be used as standard first-line treatment for patients aged 70 years and older with advanced squamous NSCLC.

Objective: Existing cross-sectional observational studies indicate that patients with multiple myeloma experience negative physical and psychological symptoms and low health-related quality of life. The study aim was to determine symptom prevalence, health-related quality of life and symptoms associated with health-related quality of life in patients with newly diagnosed multiple myeloma. Methods: This multicenter longitudinal cohort study was conducted in four hospitals in Japan. Patients with newly diagnosed multiple myeloma were asked to report their symptom intensity and health-related quality of life using validated questionnaires at three points: at diagnosis (T1), 1 month (T2) and 12 months after diagnosis (T3). Symptoms associated with health-related quality of life were explored using a mixed-effects model. Results: A total of 106 patients completed the assessment at T1. The symptoms more than 30% of patients reported were pain, disturbed sleep and distress at T1, pain, dry mouth, disturbed sleep and fatigue at T2, fatigue, numbness of tingling and pain and numbness or tingling at T3. Pain and depression were significantly associated with health-related quality of life negatively. Conclusions: The finding suggests that more than 30% of multiple myeloma patients suffered from pain and various symptoms and they received suboptimal palliative care within a year after starting initial chemotherapy. Pain and depression should be the main targets of interventions to improve health-related quality of life in this population.

Asthma is a heterogeneous disease, and phenotyping can facilitate understanding of disease pathogenesis and direct appropriate asthma treatment. This nationwide cohort study aimed to phenotype asthma patients in Japan and identify potential biomarkers to classify the phenotypes. Adult asthma patients (n = 1925) from 27 national hospitals in Japan were enrolled and divided into Global Initiative for Asthma (GINA) steps 4 or 5 (GINA 4, 5) and GINA Steps 1, 2, or 3 (GINA 1-3) for therapy. Clinical data and questionnaires were collected. Biomarker levels among GINA 4, 5 patients were measured. Ward's minimum variance hierarchical clustering method and tree analysis were performed for phenotyping. Analysis of variance, the Kruskal-Wallis, and chi-square tests were used to compare cluster differences. The following five clusters were identified: 1) late-onset, old, less-atopic; 2) late-onset, old, eosinophilic, low FEV₁; 3) early-onset, long-duration, atopic, poorly controlled; 4) early-onset, young, female-dominant, atopic; and 5) female-dominant, T1/T2-mixed, most severe. Age of onset, disease duration, blood eosinophils and neutrophils, asthma control questionnaire Sum 6, number of controllers, FEV₁, body mass index (BMI), and hypertension were the phenotype-classifying variables determined by tree analysis that assigned 79.5% to the appropriate cluster. Among the cytokines measured, IL-1RA, YKL40/CHI3L1, IP-10/CXCL10, RANTES/CCL5, and TIMP-1 were useful biomarkers for classifying GINA 4, 5 phenotypes. Five distinct phenotypes were identified for moderate to severe asthma and may be classified using clinical and molecular variables (Registered in UMIN-CTR; UMIN000027776.).
