The Global Alliance for Genomics and Health (GA4GH) aims to accelerate biomedical advances by enabling the responsible sharing of clinical and genomic data through both harmonized data aggregation and federated approaches. The decreasing cost of genomic sequencing (along with other genome-wide molecular assays) and increasing evidence of its clinical utility will soon drive the generation of sequence data from tens of millions of humans, with increasing levels of diversity. In this perspective, we present the GA4GH strategies for addressing the major challenges of this data revolution. We describe the GA4GH organization, which is fueled by the development efforts of eight Work Streams and informed by the needs of 24 Driver Projects and other key stakeholders. We present the GA4GH suite of secure, interoperable technical standards and policy frameworks and review the current status of standards, their relevance to key domains of research and clinical care, and future plans of GA4GH. Broad international participation in building, adopting, and deploying GA4GH standards and frameworks will catalyze an unprecedented effort in data sharing that will be critical to advancing genomic medicine and ensuring that all populations can access its benefits.

BACKGROUND: Secukinumab, a fully human monoclonal antibody that directly inhibits interleukin 17A, has shown significant and sustained improvement in the signs and symptoms of ankylosing spondylitis over 3 years in the MEASURE 2 study. We report the 5-year (end-of-study) results of subcutaneous secukinumab 150 mg in the MEASURE 2 study. METHODS: MEASURE 2 was a phase 3, double-blind, randomised, placebo-controlled, study done in 13 countries and 53 centres. Patients with ankylosing spondylitis who were 18 years of age or older and fulfilled the modified New York criteria were randomly assigned to receive secukinumab (150 mg or 75 mg) or placebo subcutaneously at baseline and weeks 1, 2, and 3, and then every 4 weeks from week 4. At week 16, patients initially given placebo were randomly assigned again (placebo switchers) to receive secukinumab 150 mg or 75 mg. Efficacy results are reported for patients initially randomised to secukinumab 150 mg and those who switched from placebo to secukinumab 150 mg at week 16. An optional dose escalation from secukinumab 75 mg to 150 mg was initiated beginning week 140. We assessed efficacy endpoints at week 260 (5 years), including Assessment of Spondyloarthritis International Society (ASAS) 20 and ASAS 40, inactive disease according to ankylosing spondylitis disease activity score with C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASDAI50, Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index, Short Form-36 Physical Component Summary, and ASAS partial remission. Analyses were stratified by anti-tumour necrosis factor (TNF) status (anti-TNF-naive and anti-TNF inadequate response). The safety analysis included all patients who received one dose or more of secukinumab. We report data as observed without accounting for missing data. The MEASURE 2 study was registered with ClinicalTrials.gov, NCT01649375. FINDINGS: 219 patients were randomly assigned during the trial and 150 (68%) completed 5 years of treatment, including 82 (77%) of 106 patients in the secukinumab 150 mg group and 68 (65%) of 105 in the secukinumab 75 mg group. Efficacy analysis in the secukinumab 150 mg group included 53 patients who completed the study and one additional patient who was assessed in the treatment period weeks 212-260, but did not complete the study. 134 (61%) of 219 patients were anti-TNF-naive and 85 (39%) were anti-TNF inadequate responders. ASAS responses at 5 years with secukinumab 150 mg were 36 (67%) of 54 patients (ASA20) and 27 (50%) patients (ASAS40). Sustained improvement was observed across other efficacy endpoints with secukinumab 150 mg at 5 years. At 5 years, the proportion of patients achieving efficacy endpoints of BASDAI 50 response was 53% (44/83); ASAS 5/6 response was 51% (42/83); ASDAS-CRP inactive disease was 21% (17/81); and ASAS partial remission was 25% (21/83). Exposure-adjusted incidence rates with any secukinumab dose for selected adverse events were 1·0 per 100 patient-years (95% CI 0·4-1·9) for Candida infections, 0·5 (0·1-1·2) for Crohn's disease, 0·4 (0·1-1·1) for ulcerative colitis, 0·6 (0·2-1·4) for major adverse cardiovascular events, 0·5 (0·1-1·2) for uveitis, and 0·6 (0·2-1·4) for malignant or unspecified tumours. INTERPRETATION: Secukinumab 150 mg provided sustained improvement in the signs, symptoms, and physical function in patients with ankylosing spondylitis after 5 years of treatment. The safety profile of secukinumab remained consistent with previous reports. FUNDING: Novartis Pharma.

Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodiversity conservation, ecosystem and landscape management, restoration, biogeography and earth system modelling. Since its foundation in 2007, the TRY database of plant traits has grown continuously. It now provides unprecedented data coverage under an open access data policy and is the main plant trait database used by the research community worldwide. Increasingly, the TRY database also supports new frontiers of trait-based plant research, including the identification of data gaps and the subsequent mobilization or measurement of new data. To support this development, in this article we evaluate the extent of the trait data compiled in TRY and analyse emerging patterns of data coverage and representativeness. Best species coverage is achieved for categorical traits-almost complete coverage for 'plant growth form'. However, most traits relevant for ecology and vegetation modelling are characterized by continuous intraspecific variation and trait-environmental relationships. These traits have to be measured on individual plants in their respective environment. Despite unprecedented data coverage, we observe a humbling lack of completeness and representativeness of these continuous traits in many aspects. We, therefore, conclude that reducing data gaps and biases in the TRY database remains a key challenge and requires a coordinated approach to data mobilization and trait measurements. This can only be achieved in collaboration with other initiatives.

AIMS: To further characterise biphasic squamoid renal cell carcinoma (RCC), a recently proposed variant of papillary RCC. METHODS AND RESULTS: We identified 28 tumours from multiple institutions. They typically showed two cell populations-larger cells with eosinophilic cytoplasm and higher-grade nuclei, surrounded by smaller, amphophilic cells with scanty cytoplasm. The dual morphology was variable (median 72.5% of tumour, range 5-100%); emperipolesis was found in all cases. The male/female ratio was 2:1, and the median age was 55 years (range 39-86 years). The median tumour size was 20 mm (range 9-65 mm). Pathological stage pT1a was found in 21 cases, pT1b in three, and pT3a and pT3b in one each (two not available). Multifocality was found in 32%: multifocal biphasic RCC in one case, biphasic + papillary RCC in two cases, biphasic + clear cell RCC in three cases, biphasic + low-grade urothelial carcinoma of the renal pelvis in one case, and biphasic + Birt-Hogg-Dubé syndrome in one case. Positive immunostains included: PAX8, cytokeratin (CK) 7, α-methylacyl-CoA racemase, epithelial membrane antigen, and vimentin. Cyclin D1 was expressed only in the larger cells. The Ki67 index was higher in the larger cells (median 5% versus ≤1%). Negative stains included: carbonic anhydrase 9, CD117, GATA-3, WT1, CK5/6, and CK20; CD10 and 34βE12 were variably expressed. Gains of chromosomes 7 and 17 were found in two evaluated cases. Follow-up was available for 23 patients (median 24 months, range 1-244 months): 19 were alive without disease, one was alive with recurrence, and one had died of disease (two had died of other causes). CONCLUSIONS: Biphasic papillary RCC is a rare variant of papillary RCC, and is often multifocal.
