AUSTIN, Texas, Aug. 18, 2022 (GLOBE NEWSWIRE) — Cassava Sciences, Inc. (Nasdaq: SAVA), a clinical-stage biotechnology company focused on Alzheimer’s disease, was recently informed by the Alzheimer’s Disease Prevention Journal (JPAD) that there is no compelling evidence to support claims of data manipulation in a 2020 paper on simufilam co-authored by company staff and collaborating scientists.

JPAD provided the following statement to the Company on Monday, August 15 after market close, which is reproduced in full below:

We have completed our review of your article “PTI-125 Reduces Biomarkers of Alzheimer’s Disease in Patients” (JPAD 2020;7(4):256-264). We find no convincing evidence of data manipulation or intent to mislead, and therefore take no action regarding the published article..”

“From the start, I have said that the research misconduct allegations are false, and for good reason – I see no evidence to support these allegations,” said Remi Barbier, President and CEO. direction. “I hope that the written statements of neutral and independent scientific experts will help close the chapter of baseless attacks on our science. At some point, it becomes irrational for our detractors to repeat the same tired old mantra of data manipulation over and over again.

  • In May 2022, Neurobiology of aging investigated and found no evidence of data manipulation in an article on simufilam published in this journal in 2017. The editor of the journal stated: “A reader informed the editors of concerns about the aforementioned report published on Neurobiology of Aging [i.e., “PTI-125 binds and reverses an altered conformation of filamin A to reduce Alzheimer’s disease pathogenesis.” Neurobiol. Aging, 55:99-114]. These questions were forwarded to the authors, who provided a detailed response, including uncropped Western blot images and relevant photomicrographs, as requested by the editor. The material was evaluated by an independent expert with relevant methodological expertise, the manuscript was scanned by AI-based figure checking software (i.e. Proofig) and all available inputs were taken taken into account by the Processing Editor and the Editor-in-Chief. Overall, the editors found no compelling evidence of data manipulation intended to distort the results..” The full journal record is available online:
  • In December 2021, Cassava Sciences announced that Neuroscience investigated and found no evidence of data manipulation in an article published in this journal in 2005.

A related investigation by academic authorities at the City University of New York (CUNY) is ongoing. Pending a public response from CUNY, the two Neurobiology of aging and Journal of Neuroscience previously published an exceptional “expression of concern,” which is a type of non-standard editorial notice used by academic publishers to raise awareness of a possible problem, according to the Council of Science Editors (2012).
