Multispecific antibody developers in the clinic
Companies with at least one bispecific, trispecific or multispecific antibody in a registered trial. A company with a multispecific already in the clinic is a company that builds, buys or licenses binders for that format, and it needs more of them for whatever comes next in its pipeline.
Who holds it: at an emerging biotech, the CSO or the head of antibody discovery or protein engineering. At a large or mid-size pharma company, the biologics research lead signs off on the science and a search and evaluation or external innovation team runs the deal.
Who holds the license: business development and licensing. A platform license and a discovery program are usually decided by different people inside the same company.
About 80
companies sponsoring at least one trial with a US site, started since 2021, that names a multispecific format. A floor: programs that have not reached the clinic do not appear.
