Synaptogenix Completes Patient Enrollment in NIH Sponsored Phase 2b Alzheimer's Disease Trial

- Top line results expected during the fourth quarter of 2022

- Data Safety Monitoring Board has confirmed no adverse safety issues

NEW YORK, April 19, 2022 /PRNewswire/ -- Synaptogenix, Inc. (Nasdaq: SNPX) ("the Company"), a clinical-stage biopharmaceutical company developing regenerative therapeutics for neurodegenerative disorders, today announced that it has completed enrolling its target of 100 patients for its ongoing National Institutes of Health ("NIH") sponsored Phase 2b clinical trial of Bryostatin-1 for patients suffering from advanced and moderately severe Alzheimer's disease ("AD"). The Company expects to announce topline data from the study during the fourth quarter of 2022.

Synaptogenix also reports that the independent Data Safety Monitoring Board ("DSMB") overseeing the trial has confirmed the absence of any drug-related adverse safety issues.

Bryostatin-1 caused highly significant cognitive enhancement (4.0 SIB psychometric score above baseline) for the pre-specified patients who received Bryostatin-1 in the absence of Namenda in our two previous, consolidated 3-month pilot trials, recently published in a peer-reviewed article (JAD, 2022) – while the Placebo-treated patients showed no significant benefit. Bryostatin-1 treatment has now been extended to include double the number of doses (N = 14) in the current 6-month, placebo-controlled trial, in which randomized enrollment has been carefully controlled for balanced baselines in the treatment and placebo cohorts. Patients will have been observed for as long as three months after all dosing cessation, given the persistence of benefit for at least 30 days after dosing that was previously observed.

"We are encouraged that the top line data due in the 4^th quarter, 2022, will reflect the same or greater benefit already observed for patients in identical, previously treated pre-specified cohorts in our previous Phase 2a pilot trials. The absence of any drug-related adverse events, as have been observed with the few other therapeutic strategies reaching limited Food and Drug Administration ("FDA") approval for AD, should facilitate our subsequent steps toward clinical utility. Benefits of at least 4.0 SIB scores, above baseline, are likely to be clinically meaningful, and therefore have the potential to treat the underlying disease as well as to provide symptomatic relief," stated Daniel Alkon, MD, the Company's President and Chief Scientific Officer.

Alan Tuchman M.D., the Company's Chief Executive Officer, stated, "Evidence is growing and continues to support Bryostatin-1 as a potential treatment for Alzheimer's disease. We are excited today to announce the completion of our Phase 2b enrollment and we are eagerly awaiting the read out of our top line data later this year."

About Synaptogenix, Inc.

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.
