Rethinking phase 2 trials in amyotrophic lateral sclerosis

Michael Benatar, Christopher McDermott, Martin R. Turner et al. · 2024 · Brain

There is a long history in amyotrophic lateral sclerosis (ALS) of promoting therapies based on phase 2 data, which then fail in phase 3 trials. Experience suggests that studies of 6 months in duration are too short, especially with…

Risk-Return Analysis of the Biopharmaceutical Industry as Compared to Other Industries

Cedric Popa, Karel Holvoet, Tessa Van Montfort et al. · 2018 · Frontiers in Pharmacology

Background: Profits in the biopharmaceutical industry have been scrutinized in social debate. However, drawing conclusions based on industry profitability only is inappropriate as such an analysis does not account for risks faced by investors. This study aims to measure risks and returns in the biopharmaceutical industry and investigates whether risk-adjusted return on investment in the biopharmaceutical industry is higher than that in other industries. Methods: To enable appropriate comparison, we identified six benchmark industries with characteristics that match those of the biopharmaceutic

Machine Learning Did Not Outperform Conventional Competing Risk Modeling to Predict Revision Arthroplasty

Jacobien H. F. Oosterhoff, Anne de Hond, Rinne M Peters et al. · 2024 · Clinical Orthopaedics and Related Research

BACKGROUND: Estimating the risk of revision after arthroplasty could inform patient and surgeon decision-making. However, there is a lack of well-performing prediction models assisting in this task, which may be due to current conventional…

CAR T-Cell Targeting of Macrophage Colony-Stimulating Factor Receptor

Daniela Achkova, Richard Beatson, John Maher · 2022 · Cells

Macrophage colony-stimulating factor receptor (M-CSFR) is found in cells of the mononuclear phagocyte lineage and is aberrantly expressed in a range of tumours, in addition to tumour-associated macrophages. Consequently, a variety of cancer therapies directed against M-CSFR are under development. We set out to engineer chimeric antigen receptors (CARs) that employ the natural ligands of this receptor, namely M-CSF or interleukin (IL)-34, to achieve specificity for M-CSFR-expressing target cells. Both M-CSF and IL-34 bind to overlapping regions of M-CSFR, although affinity of IL-34 is significa

A specific microRNA profile as predictive biomarker for systemic treatment in patients with metastatic colorectal cancer

Dennis Poel, Elske C. Gootjes, Lotte Bakkerus et al. · 2020 · Cancer Medicine

BACKGROUND: Palliative systemic therapy is currently standard of care for patients with extensive metastatic colorectal cancer (mCRC). A biomarker predicting chemotherapy benefit which prevents toxicity from ineffective treatment is urgently needed. Therefore, a previously developed tissue-derived microRNA profile to predict clinical benefit from chemotherapy was evaluated in tissue biopsies and serum from patients with mCRC. METHODS: Samples were prospectively collected from patients (N = 132) who were treated with capecitabine or 5-FU/LV with oxaliplatin ± bevacizumab. Response evaluation wa

Both species richness and growth forms affect nutrient removal in constructed wetlands: A mesocosm experiment

Yumei Luo, Quan Chen, Fan Liu et al. · 2023 · Frontiers in Ecology and Evolution

Introduction Plant richness is thought to improve the function of constructed wetlands (CWs), but most CWs are planted with monocultures, with only a few employed polycultures, which have drawn contradictory conclusions. We suppose functional diversity is the key to better performance of plant communities and hypothesize that CWs planted with diverse growth forms are superior in plant growth and nutrient removal. Methods In this study, six emergent plant species categorized into slender type ( Schoenoplectus tabernaemontani, Typha orientalis ), fan type ( Iris sibirica, Acorus calamus ) and la

Majority language skill, not measures of bilingualism, predicts executive attention in bilingual children

David Giguere, Daniel J. Dickson, Michelle K. Tulloch et al. · 2021 · Journal of Experimental Child Psychology

Evidence is mixed regarding whether and why bilingual children might be advantaged in the development of executive functions. Five preregistered hypotheses regarding sources of a bilingual advantage were tested with data from 102 Spanish-English bilingual children and 25 English monolingual children who were administered a test of executive attention, the flanker task, at 7, 8, and 9 years of age. Measures of the children's early and concurrent bilingual exposure and their concurrent English and Spanish skill were available from a larger longitudinal study in which these children participated.
