Implementation of a Breakthrough Brain DDS

Braizon is driven to help all those who suffer from brain diseases.

Alzheimer’s disease, Parkinson’s disease, brain tumors, stroke, and ALS are just a few of the many types of central nervous system (CNS) disorders. These diseases affect basic human dignity not only for the affected individuals, but also impact the quality of life for their family members who must often provide most of the patient care for their loved one. Tragically, despite great advances in other areas, survival rates for children with refractory brain cancer are still very low.

We think our technology can provide solutions to relieve this suffering.

One major hurdle to treat CNS diseases is a natural barrier between the blood, which carries most drugs, and the brain tissue where they act. This makes it is more difficult to deliver drugs to brain than other organs in our body. Pharmaceutical companies produce medicines, but these medicines can only succeed if enough reaches the brain.

From Academia Origin to Broad Utility for Drug Delivery

Our technology is a drug delivery system (DDS) for non-invasively crossing the brain blood barrier by ligand modification of polymer micelle drug carriers.

Derived from joint research by Dr. Takanori Yokota, Professor in the Department of Neurology at Tokyo Medical and Dental University and Dr. Kazunori Kataoka, Professor in the School of Engineering at the University of Tokyo, this revolutionary technology is receiving worldwide attention.

Dr. Yokota was inspired by the high accumulation of glucose in the brain during scans used for the early detection of cancer by imaging glucose uptake. While direct modification of drugs with glucose does not improve uptake into the brain, Dr. Kataoka’s delivery techniques solve this problem.

His solution is polymer nano-micelles modified to present glucose on their surfaces. Together these key opinion leaders in their respective fields conceived of an idea that can deliver drugs to brain by utilizing the glucose transport mechanism.

By controlling the site of expression of the most abundant and active nutrient BBB transporter, Glucose Transporter 1, with glycemic control this technology increases the targeted delivery of drugs into the brain more than 50-fold. As exclusive license holders for the patent on this technology Braizon was created to commercialize the research results as a DDS platform.

And more we are one of the COINs member (COIN is the group of iCONM, which Dr. Kataoka is the head director), We are treated as basis of research output from University of Tokyo and Tokyo Medical and Dentist and University of Tokyo.

We could promote Trans-Relation with support by University of Tokyo and Tokyo Medical and Dentist,so our business is the top running example of Cooperation between medical industry and Industry.

Strategic business development based on I.P.

Our DDS techniques were registered as patent in Feb 2017.

We have already applied material patent as of micelles which are relative to DDS with this strong basic patent.

We had already started making miseclle for pharmatical companies.such that has a strong needs to develop drugs deliver to brain,and improve drugs delivery rate,and proceeded patent licensing business by appropliating basic technologies.

We could apply our DDS technology for any sorts of molecule,small molecule,nuclecacid,antibody,peptide,and could deliver to brain.

And we might reposition drugs all ready made by solving problems to DDS for such drugs.

We will strengthen R&D structure and manufacturing miscelle team for promoting feastibility study and co-research and development with pharmateutical companies.We opened Boston R&D site in LabCentral April 2019 for proceeding collaboration with pharmateutical company more smoothly.


We have a dream.One day we can resque patients all over the world who are suffered from serious brain diseases.One day we can complete development by scientists 99% perspiration and 1% inspiration,and by assistance or collabolation with pharmaceutical company.We will be committed to rising to the challenge and dream will come true.Investors,all over the world,please give us some help in terms of money.
