Neurocentria’s Candidate Compound MMFS
Improves Brain Age by 9 Years in Human Study on Older Adults
Data from double-blind placebo-controlled clinical trial, now published in the Journal of Alzheimer’s Disease, supports ongoing studies in early Alzheimer’s patients
FREMONT, Calif., Oct. 28, 2015 — Neurocentria Inc., a clinical-stage pharmaceutical company developing therapeutics to enhance brain function and correct cognitive impairment, announced the successful completion of a human study demonstrating that the company’s lead compound significantly reversed cognitive impairment in subjects 50 to 70 years old. The results have been published in the peer-reviewed Journal of Alzheimer’s Disease.
Alzheimer’s, and the high-risk condition that precedes it—Mild Cognitive Impairment—together affect more than 11 million Americans. Mild Cognitive Impairment increases the risk of Alzheimer’s by up to tenfold. Alzheimer’s is both the most common cause of dementia and the sixth leading cause of death in the United States. In 2015, Alzheimer’s and other dementias will cost the nation $226 billion—a number that’s expected to rise as high as $1.1 trillion by 2050, according to The Alzheimer’s Association. Yet there is currently no FDA-approved treatment to prevent the disease or stop it from progressing.
The trial evaluated human efficacy for Neurocentria’s MMFS-01, an oral compound designed to increase synaptic density in brain regions critical for executive function and memory, including the prefrontal cortex and hippocampus. Synaptic loss is the hallmark of cognitive decline in aging, Alzheimer’s and most other neurological diseases that present with cognitive impairment.
The double-blind, placebo-controlled clinical trial demonstrated with high statistical significance (p <0.01) that MMFS improved subjects’ overall cognitive ability, as determined by a composite score of tests in four major cognitive domains: executive function, working memory, attention and episodic memory.
Importantly, MMFS improved cognitive function performance seen at baseline, while the majority of human clinical trials for other Alzheimer’s drugs under development are focused on slowing down cognitive decline. In addition, it achieved statistical significance in just six weeks of treatment. For comparable drugs, statistical significance has been seen after much longer timeframe, ranging from 12 to 72 weeks.
The study results have clinical significance. The study measured the “brain age” of subjects based on their executive function performance. The brain age of study participants taking MMFS improved by nine years after six weeks of treatment, and persisted after 12 weeks of treatment. By contrast, participants who received a placebo saw little change in their average brain age. These data demonstrate that MMFS is effective at reversing cognitive deficit. The study also showed that MMFS was well tolerated; all adverse events were of mild severity, and there were a greater number of such events under placebo versus treatment conditions.
“The results suggest an exciting potential for MMFS to treat cognitive impairment in the elderly,” said Zhong-Lin Lu, a co-author of the study and director of the Center for Cognitive and Behavioral Brain Imaging and director of the Center for Cognitive and Brain Sciences at The Ohio State University. “Synaptic loss is a hallmark of the aging brain, resulting in cognitive impairments that can severely affect the quality of life. Neurocentria’s approach has been shown to successfully restore brain functions in humans, reinforcing what we have seen in extensive preclinical research.”
Neurocentria’s compound has a novel, disease-agnostic mechanism of action that expands on more than a decade of neuroscience research and discovery published in journals such as Nature and Neuron, and carried out at the Massachusetts Institute of Technology, Tsinghua University in Beijing and the company’s Silicon Valley headquarters. The company’s early work focused on uncovering the principles behind synaptic regulation, which led to the discovery of a novel mechanism for upregulating synaptic density and plasticity. With this understanding, Neurocentria developed MMFS, which drives mitochondrial energy production, synaptogenesis and synaptic plasticity.
“The effect size for change in overall cognitive ability was robust—two to three times greater than what’s been reported for current treatments and other leading drug candidates in the cognitive impairment space,” said Guosong Liu, M.D., Ph.D., CEO of Neurocentria, noting that the large effect size, measured by Cohen’s d, means fewer subjects will be needed to demonstrate the compound’s effectiveness in Phase III trials for FDA drug approval.
Neurocentria has an ongoing trial at Stanford University testing the efficacy of its lead compound for improving cognitive function and brain metabolism in mild to moderate Alzheimer’s patients, with expected completion in the fourth quarter of 2015. Neurocentria expects to begin late-stage trials next year.

Neurocentria, Inc. to Present New Data on MMFS in Mild-Moderate
Alzheimer’s Disease at Alzheimer’s Association International Conference
WALNUT CREEK, California., July 13, 2017 /PRNewswire/ — Neurocentria, Inc., a privately held clinical phase pharmaceutical company developing novel therapies for the treatment of Alzheimer’s (AD) and other neurodegenerative diseases, today announced the presentation, which will take place at the 2017 Alzheimer’s Association International Conference (AAIC) being held in London from July 16-20.

MMFS Treatment Ameliorates Frontal Cortex Dysfunction in Mild-Moderate Alzheimer’s Disease Patients

The presentation will report the results of a recently completed proof-of-concept study of MMFS in mild-moderate AD patients. The study was initiated as a follow-up to a previous trial of MMFS in older adults with mild cognitive impairment (MCI). In that double-blind, placebo-controlled trial (N=50), MMFS significantly improved overall cognitive ability in older adults with MCI after six weeks of oral intake. Cognitive ability was assessed with a neuropsychological test battery (NTB; Cohen’s d = 0.74, 0.91 at 12 weeks); there were equal or fewer adverse events compared with placebo, and all events were mild.
The results from these two human studies have prompted Neurocentria to pursue the development of MMFS for treating early AD. Phase II/III trials are planned to begin in 2018 to follow up on these promising findings, and Neurocentria is currently recruiting U.S. sites.
Neurocentria’s candidate compound, MMFS, has a novel mechanism of action – increasing synaptic density and functionality. MMFS is backed by more than 15 years of preclinical research at Stanford, MIT, and Tsinghua University. The active ingredient in MMFS is L-Threonic Acid Magnesium Salt (L-TAMS; also published as Magnesium L-Threonate, MgT). Evidence supports at least three pathways to efficacy: upregulation of NMDA receptor expression, and improvement of mitochondrial function that both augments synaptic protein transport and decreases BACE-1-mediated Aβ deposition. MMFS treatment prevents and restores synaptic loss and cognitive impairment in AD-model mice.
Neurocentria is a clinical stage pharmaceutical company dedicated to improving quality of life by enhancing brain function and reversing cognitive impairment. Neurocentria’s novel approach of reversing synaptic loss stems from more than 15 years of pre-clinical research focused on understanding synaptic regulation and function. The company’s candidate compound for Alzheimer’s disease, MMFS, is based on a broad set of pre-clinical and human data demonstrating high tolerability and statistical significance in increasing synaptic density and function and improving overall cognitive ability, including working memory, executive function, episodic memory and attention domains. Beyond Alzheimer’s, Neurocentria is carrying out multiple human trials to test MMFS’ efficacy in other neurological conditions that present with untreatable cognitive impairment, including adult attention-deficit/hyperactivity disorder (ADHD) and schizophrenia.
