CERES aspires to revolutionize the treatment paradigm for neurological diseases characterized by bioenergetic deficiencies

INTEGRATIVE TECHNOLOGY TO PROVIDE
BRAIN CELLS WITH CREATINE

Ceres relies on its distinctive and innovative Creatine-to-Neurons™ approach to supply brain cells with creatine. This approach consists of creatine prodrugs, a highly innovative formulation ensuring the stability and sprayability of the prodrug, and intra-nasal delivery to target the Nose-to-Brain pathway.

As of today, Ceres Brain Therapeutics stands as the sole entity capable of delivering creatine to cerebral neurons. This groundbreaking method opens the door to a myriad of clinical applications, including rare genetic diseases characterized by a primary lack of cerebral creatine, conditions related to mitochondrial deficiencies, epigenetic diseases, and broader societal health issues

Creatine

Creatine is a naturally occurring compound within cells, playing a crucial role in cellular energy production. It is synthesized in the body from the amino acids arginine, glycine, and methionine, primarily in the kidneys and liver.

Additionally, creatine is also present in certain animal-derived foods such as meat and fish. On a cellular scale, creatine is converted into creatine phosphate, a molecule that rapidly stores and releases energy, facilitating the regeneration of ATP, the primary cellular energy source.

Creatine has garnered increasing interest in the field of neurological diseases due to its potential neuroprotective properties. Studies show that creatine exert beneficial effects on cellular health by reducing oxidative stress and modulating various cellular signaling pathways.

Furthermore, it appears to possess neuroprotective properties, holding potential in the treatment of certain neurologic diseases such as degenerative diseases, traumatic brain injuries, stroke, age-related loss of cognitive function and more generaly cognitive impairments.

Creatine, although naturally occurring in the body, may face challenges in crossing blood-brain barrier due to the creatine transporter that can be saturated, impaired or lacking. Dopaminergic neurons, which produce the neurotransmitter dopamine, are particularly sensitive to this access restriction.

Platform

The Ceres Brain’s platform allows bringing drug candidate that do not reach the brain, into brain cells and more specifically into the neurons. This lack of passage may be due to rapid degradation in the body, caused by the action of liver enzymes or the blood-brain barrier. The “Nose-to-Neurons” Ceres Brain’s platform is aimed to circumvent these issues.
