Dren Bio is a privately-owned biopharmaceutical company that specializes in the development of therapeutic antibodies for the treatment of serious diseases such as cancer and autoimmune disorders.

Read full description

Their primary product, DR-01, is part of their enhanced antibody-dependent cellular cytotoxicity (ADCC) program. In simple terms, ADCC is a mechanism that our immune system uses to kill cells that are harmful or infected. DR-01 is designed to induce a strong immune response that kills a type of cell responsible for various blood cancers. Besides blood cancers, DR-01 will also be tested for its effectiveness in treating autoimmune diseases with no current approved therapies.

Dren Bio's second program involves a proprietary technology that uses bispecific antibodies, which are engineered antibodies that can bind to two different types of cells at the same time. This technology provides a new way of fighting cancer by directly engaging cancer cells, stimulating immune cells to change the tumor environment, killing tumor cells, and activating specific immune responses against the tumor.

The company generates revenue through the development and potential commercialization of these therapeutic antibodies.
