The Silicon Review
Cancer is one of the leading causes of deaths the world over, killing hundreds of thousands and affecting the lives of the loved ones of the departed. In spite of such a high rate of casualties and over a billion dollars spent on developing a cure, cancer remains one of the most elusive diseases known to science. Some of the best and brightest minds in science have spent their entire careers in research, trying to find a cure but having limited success. To add to the woes of patients suffering from this deadly disease, the cost of treatments often end up driving the patient into poverty. Several institutions have developed various techniques of battling cancer and one among them which shows considerable promise is called immune-oncology.
Immuno-oncology is a rapidly evolving and complex field that offers great potential to deliver substantial benefits to patients with a range of different cancers. A number of approved therapies already exist that offer impressive and long-lasting responses in some patients. A company named Biotecnol has made headways into the applications of immune-oncology.
Fight against Cancer
Biotecnol is working in the field of immuno-oncology and is using proprietary antibody-based technologies to engineer and develop highly- targeted therapeutic products which utilize a patient’s own immune system to fight cancer. These powerful approaches are based on directing or modulating a patient's own T-Cells or NK-Cells to kill the tumors. The T and NK white blood cells are the most potent killing-cells of the human immune system. Other strategies being developed by Biotecnol include means to modulate key immune-checkpoint regulators for manipulating endogenous anti-tumor immunity, again using the patient's own immune system.
Biotecnol engineers Tribody™ molecules, which are multi-specific antibody products i.e. highly specific and highly directed molecules with more than one function. As a result a Tribody™ molecule is characterized by an unsurpassed versatility and ease of manipulation; they are engineered to incorporate up to three different specific binding sites (imagine as an analogy, "3 specific magnets" engineered and linked together in one single unit, with selectivity to a "specific metal" of your choice) which when assembled, can combine different immunological and targeting function. For example they have the ability to recruit potent immune-effector cells like T-cells or NK-cells whilst retaining the ability to direct them to the tumor by target with high precision, more than one "epitope", (which is a binding site in a tumor cell), or more than one target antigen (a biological marker expressed by a cancer cell) in the same tumor, all with one single molecule. These approaches are powerful tools to address the treatment of highly heterogeneous and highly aggressive tumors.
Clinical research in oncology has evolved significantly over the last 5 years. Novel protocols using combination therapies of a variety of novel biological and traditional chemical agents have shown great promise in managing survival in cancer patients. Biotecnol’s strategy is to work with top cancer institutions in the immune-oncology field which will help the company to accelerate the development of cutting-edge therapeutic approaches to fight cancer, especially in solid tumors, an area which is in great demand for effective products.
The Tribody™ technology enables the generation of multi-specific antibody products. This unique technology overcomes the key shortcomings of conventional mono and currently developed bi-specific antibody formats. With the Tribody™ technology, Biotecnol can engineer and assemble recombinant antibodies in a rational manner in order to design a chosen mechanism of action to address the killing of a specific tumor type. An anti-CD3 antibody which binds the T-cells is engineered in the Tribody™ "scaffold" where additional tumor antigens are also engineered. The Tribody™ then crosslinks tumor antigens and T-cells to initiate the tumor-cell killing process.
Trisoma® is a high-throughput, powerful and well-controlled platform based on proprietary methods and protocols for generating and characterizing a Tribody™ candidate drug substance. The Trisoma® platform is used for the assembly, engineering, and testing of various Tribody™ molecules with various distinct properties under various structural formats with optimal stability and desired pharmacological properties in terms of bio-availability.
Biotecnol is constantly improving on the engineering of the Trisoma® platform and its associated technology in order to build new intellectual property and optimize the characteristics of such versatile Tribody™ derived molecules.
