About AbTis

AbTis is a biotechnology company that specializes in antibody-drug conjugates (ADC) platform technology with its own proprietary patents and its own pipelines in developments in oncology areas.

AbTis pipelines are designed to enhance the safety and efficacy of the current antibody-drug conjugates by applying AbTis linker to the mAbs. Its platform ADC linker technology is site-specific and applicable to the native antibodies, commercial antibodies, or novel antibodies under development as it requires no mutation or engineering to antibody itself. Its stable, hydrophilic and cleavable linkers can be attached to various payloads, too.

Under the moto of "Patients First", AbTis has been striving to advance its ADC technology and to develop its pipelines with several other antibody and payload companies. AbTis' advanced ADC technology enables partners to co-develop pipelines together in a real open innovation setting.
