About Antikor

Antikor Biopharma is developing a unique and innovative class of Antibody Drug Conjugate (ADC) therapy called Fragment Drug Conjugates (FDCs). FDCs offer potential benefits over larger ADCs in the treatment of solid tumours due to their rapid penetration, delivery of high amounts of cytotoxic payload and fast clearance from normal tissues, resulting in better tolerability and a high therapeutic index. Antikor has developed their technology platform and are developing first oncology products in areas of high clinical unmet need.

Recent deals in the ADC area demonstrates how established this technology has become and how valuable this emerging area is. Antikor’s more advanced and focussed approach creates a major opportunity to bring differentiating products for solid cancers into clinical development. 

In 2022, Antikor secured a major government grant and new investment to continue developing products for gastric cancer other solid tumours. The Company also expects to hit key milestones in 2022-3 to enable it to further expand and consolidate the team to work with pharmaceutical company partners and on further projects. Hence these are exciting and progressive times for Antikor!
