Despite the COVID-19 pandemic, a number of high-value deals involving bispecific antibodies have been signed in the past 2 years, focused on harnessing the potential of this platform to treat cancer. In this Feature, we look back at some of the key deals with the help of Clarivate Analytics.

Seven deals involving bispecifics had a total potential value of more than $1 billion (Table 1). The largest deal was signed between AbbVie and Genmab in June 2020; the two companies collaborated to develop Genmab’s pipeline of bispecific molecules that target CD3 as well as a particular tumor antigen to direct cytotoxic T cells to tumors expressing that antigen. AbbVie agreed to pay Genmab $750 million upfront and up to $3.15 billion in potential milestones related to three candidates including Genmab’s epcoritamab, which is designed to bind both CD3 and CD20 and is now in a phase 3 trial for diffuse large B cell lymphoma.

Other deals also highlighted interest in pursuing novel targets with bispecific molecules, such as Bristol Myers Squibb’s potential $1.56 billion deal signed in May 2021 to gain an exclusive license to Agenus’s AGEN1777. This preclinical bispecific antibody targets the immune checkpoint TIGIT, currently one of the hottest targets in immuno-oncology.
