Concordance and discordance in SLE clinical trial outcome measures: analysis of three anifrolumab phase 2/3 trials.

Ann Rheum Dis 2022 May 17. Epub 2022 May 17.

BioPharmaceuticals R&D, AstraZeneca US, Gaithersburg, Maryland, USA

Objectives: In the anifrolumab systemic lupus erythematosus (SLE) trial programme, there was one trial (TULIP-1) in which BILAG-based Composite Lupus Assessment (BICLA) responses favoured anifrolumab over placebo, but the SLE Responder Index (SRI(4)) treatment difference was not significant. We investigated the degree of concordance between BICLA and SRI(4) across anifrolumab trials in order to better understand drivers of discrepant SLE trial results.

Methods: TULIP-1, TULIP-2 (both phase 3) and MUSE (phase 2b) were randomised, 52-week trials of intravenous anifrolumab (300 mg every 4 weeks, 48 weeks; TULIP-1/TULIP-2: n=180; MUSE: n=99) or placebo (TULIP-1: n=184, TULIP-2: n=182; MUSE: n=102). Read More

A conserved YAP/Notch/REST network controls the neuroendocrine cell fate in the lungs.

Nat Commun 2022 May 16;13(1):2690. Epub 2022 May 16.

Departments of Pediatrics, Stanford University, Stanford, CA, USA.

The Notch pathway is a conserved cell-cell communication pathway that controls cell fate decisions. Here we sought to determine how Notch pathway activation inhibits the neuroendocrine cell fate in the lungs, an archetypal process for cell fate decisions orchestrated by Notch signaling that has remained poorly understood at the molecular level. Using intratumoral heterogeneity in small-cell lung cancer as a tractable model system, we uncovered a role for the transcriptional regulators REST and YAP as promoters of the neuroendocrine to non-neuroendocrine transition.

Follow-up regimes for sick-listed employees: A comparison of nine north-western European countries.

Health Policy 2022 May 10. Epub 2022 May 10.

SINTEF Health Services Research, Klæbuveien 153, Trondheim 7037, Norway.

The Covid-19 pandemic has revealed the importance of social protection systems, including income security, when health problems arise. The aims of this study are to compare the follow-up regimes for sick-listed employees across nine European countries, and to conduct a qualitative assessment of the differences with respect to burden and responsibility sharing between the social protection system, employers and employees. The tendency highlighted is that countries with shorter employer periods of sick-pay typically have stricter follow-up responsibility for employers because, in practice, they become gatekeepers of the public sickness benefit scheme.
