Topic: Disease mechanisms in lab and animal studies
INTRODUCTION: Tauopathies are clinicopathological entities with increased and pathological deposition in glia and/or neurons of hyperphosphorylated aggregates of the microtubule-binding protein tau. In secondary tauopathies, i.e. Alzheimer's disease (AD), tau deposition can be observed, but tau coexists with another protein (amyloid-β). In the last 20 years, little progress has been made in developing disease-modifying drugs for primary and secondary tauopathies and available symptomatic drugs have limited efficacy. AREAS COVERED: The present review summarized recent advances about the development and challenges in treatments for primary and secondary tauopathies, with a focus on passive tau-based immunotherapy. EXPERT OPINION: Several tau-targeted passive immunotherapeutics are in development for treating tauopathies. At present, 14 anti-tau antibodies have entered clinical trials, and 9 of them are still in clinical testing for progressive supranuclear palsy syndrome and AD (semorinemab, bepranemab, E2814, JNJ-63733657, Lu AF87908, APNmAb005, MK-2214, PNT00, and PRX005). However, none of these nine agents have reached Phase III. The most advanced anti-tau monoclonal antibody for treating AD is semorinemab, while bepranemab is the only anti-tau monoclonal antibody still in clinical testing for treating progressive supranuclear palsy syndrome. Further evidence on passive immunotherapeutics for treating primary and secondary tauopathies will come from ongoing Phase I/II trials.

How this study scored 41/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 23 of the 56 points we could judge it on, which is 41 out of 100.
