Journal ArticleDOI
A randomized, double-blind study of AMG 108 (a fully human monoclonal antibody to IL-1R1) in patients with osteoarthritis of the knee
Stanley Cohen,Susanna Proudman,Alan Kivitz,Francis X. Burch,John Paul Donohue,Deborah Burstein,Yu-Nien Sun,Christopher Banfield,Michael S. Vincent,Liyun Ni,Debra Zack +10 more
TL;DR: The safety profile of AMG 108 SC and IV was comparable with placebo in patients with OA of the knee; however, minimal, if any, clinical benefit was observed.
Journal ArticleDOI
Comparison of health-related quality of life in rheumatoid arthritis, psoriatic arthritis and psoriasis and effects of etanercept treatment
Vibeke Strand,Veronika Sharp,Andrew S Koenig,Grace S. Park,Yifei Shi,Brian Wang,Debra Zack,David Fiorentino +7 more
TL;DR: Comparison of health-related quality of life (HRQoL) before and after treatment with etanercept in patients with moderate to severe rheumatoid arthritis, psoriatic arthritis and psoriasis using spydergram representations found patients with RA, PsA and Psoriasis demonstrated unique HRZoL profiles at baseline.
Journal ArticleDOI
Female patients with ankylosing spondylitis: analysis of the impact of gender across treatment studies
TL;DR: Women had a higher burden of disease and less improvement in AS outcome measures compared with men; this was observed despite women having a later disease onset of shorter duration; the mechanism behind this observation is unclear.
Journal ArticleDOI
RANKL is a Marker and Mediator of Local and Systemic Bone Loss in Two Rat Models of Inflammatory Arthritis
Marina Stolina,Stephen Adamu,Michael S. Ominsky,Denise Dwyer,Frank Asuncion,Zhaopo Geng,Scot Middleton,Heather Brown,Jim Pretorius,Georg Schett,Brad Bolon,Ulrich Feige,Debra Zack,Paul J. Kostenuik +13 more
TL;DR: RANKL protein was increased in rat joint extracts and serum at the earliest stages of arthritis, suggesting that RANKL is both a marker and mediator of bone loss in arthritis.
Journal ArticleDOI
Rodent Preclinical Models for Developing Novel Antiarthritic Molecules: Comparative Biology and Preferred Methods for Evaluating Efficacy
Brad Bolon,Marina Stolina,Caroline King,Caroline King,Scot Middleton,Jill Gasser,Debra Zack,Ulrich Feige +7 more
TL;DR: All RMIA are driven by overactivity of proinflammatory pathways, but the dominant molecules differ among the models, especially when the agent is a specific cytokine inhibitor.
