Passive tau-based immunotherapy for tauopathies
Francesco Panza, Vincenzo Solfrizzi, Antonio Daniele, Madia Lozupone. Handbook of clinical neurology, 2023
Topic: Disease mechanisms in lab and animal studies
Tauopathies are heterogeneous clinicopathological entities characterized by abnormal neuronal and/or glial inclusions of the microtubule-binding protein tau. In secondary tauopathies, i.e., Alzheimer's disease (AD), tau deposition can be observed, but tau may coexist with another protein, i.e., 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. Treatments are being developed to interfere with the aggregation process or to promote the clearance of tau protein. Several tau-targeted passive immunotherapy approaches are in development for treating tauopathies. At present, 12 anti-tau antibodies have entered clinical trials, and 7 of them are still in clinical testing for primary tauopathies and AD (semorinemab, bepranemab, E2814, JNJ-63733657, Lu AF87908, PNT00, and APNmAb005). However, none of these seven 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. Two other anti-tau monoclonal antibodies have been discontinued for the treatment of primary tauopathies, i.e., gosuranemab and tilavonemab. Further evidence will come from ongoing Phase I/II trials on passive immunotherapeutics for treating primary and secondary tauopathies.

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.
