Synaptogenix Announces Topline Results from NIH-Sponsored Phase 2 Clinical Trial of Bryostatin-1 for Advanced Alzheimer's Disease

NEW YORK, Dec. 16, 2022 /PRNewswire/ -- Synaptogenix, Inc. (Nasdaq: SNPX) ("Synaptogenix" or the "Company"), an emerging biopharmaceutical company developing regenerative therapeutics for neurodegenerative disorders, today announced topline data from its National Institute of Health (NIH)-sponsored Phase 2 clinical trial of Bryostatin-1 for the treatment of advanced Alzheimer's disease.

The trial's primary endpoint of change from baseline in the Severe Impairment Battery (SIB) total score assessment obtained after completion of the second course of treatment (week 28) was not met with statistical significance. An average increase in the SIB total score of 1.4 points and 0.6 points was observed for the Bryostatin-1 and placebo groups, respectively, at week 28.

"We are disappointed in the topline results from this Phase 2 trial. Having just received the primary endpoint data, we are conducting a full review of all of the trial data to determine potential next steps and will provide an update of our plans when appropriate. We are committed to creating value for our shareholders and our substantial balance sheet offers us flexibility as we determine the next steps forward," said Synaptogenix Chief Executive Officer Alan Tuchman, M.D. "We are grateful to the study participants, investigators, the National Institutes of Health, and our distinguished advisors for their important contributions."

Synaptogenix remains well-funded with approximately $38.5 million in cash as of December 15, 2022, or approximately $4.00 per share.¹

The Phase 2 clinical trial was a randomized, double-blind, placebo-controlled study comparing bryostatin-1 to placebo for long-term efficacy in the treatment of advanced and moderately severe AD in the absence of memantine. The study was conducted with financial support from the National Institute on Aging (NIA) and the National Cancer Institute (NCI), both part of the National Institutes of Health (NIH).

Synaptogenix is a clinical-stage biopharmaceutical company that has historically worked to develop novel therapies for neurodegenerative diseases. Synaptogenix has conducted clinical and preclinical studies of its lead therapeutic candidate, Bryostatin-1, in Alzheimer's disease. Preclinical studies have also demonstrated Bryostatin's regenerative mechanisms of action for the rare disease Fragile X syndrome, and for other neurodegenerative disorders such as multiple sclerosis, stroke, and traumatic brain injury. The U.S. Food and Drug Administration has granted Orphan Drug Designation to Synaptogenix for Bryostatin-1 as a treatment for Fragile X syndrome. Bryostatin-1 has already undergone testing in more than 1,500 people in cancer studies, thus creating a large safety data base that will further inform clinical trial designs.
