Antibody-drug conjugates have been an area of great interest in the oncology space in recent years, with a record rate of FDA approvals and dealmaking activity. However balancing efficacy and off-site toxicity has remained a challenge.

Some biopharma companies are investing in what they hope will be the next-generation approach to ADCs – bispecific ADCs. 

More than a dozen early-stage clinical trials are evaluating whether adding a second targeting functionality can improve the preciseness of ADCs’ tumor-targeting, as well as potentially overcome the challenge of heterogeneity in solid tumor target expression. 

Bispecific ADCs have been a hot area for dealmaking over the past year, including BMS’ $8.4 billion purchase of a bispecific ADC candidate in December, a $690 million deal between Biotheus and Hansoh this spring, and the recently announced $325 million deal between Prague-based SOTIO Biotech and Biocytogen.

SOTIO’s most advanced ADC, SOT102, is now in a phase 1/2 clinical study in the U.S. and Europe. 

To talk about biotechs in Czechia, and bispecific ADCs, our conversation this week is with Radek Špíšek, CEO of SOTIO.
