Ipsen Signs Potential $1B ADC Deal With Foreseen

Ipsen has entered an exclusive agreement with Foreseen Biotechnology to license an antibody-drug conjugate (ADC) for cancer treatment, marking a deal valued at over $1 billion. This agreement gives Ipsen global rights to develop, manufacture, and commercialize Foreseen’s ADC, known as FS001, which is in the preclinical stage and potentially first-in-class.

FS001 targets a novel antigen that is overexpressed in numerous solid tumors. Foreseen identified this antigen using proprietary proteomic and AI-powered platforms and discovered that it plays a significant role in tumor growth and metastasis. Preclinical studies have demonstrated FS001’s efficacy in cancer models resistant to multiple drugs. Under the terms of the agreement, Ipsen will handle preparation for Phase I clinical trials, including the submission of an IND application, as well as overseeing all clinical development, manufacturing, and commercialization efforts.

Mary Jan Hinrichs, Ipsen’s senior vice president of early development, expressed optimism about the FS001 program, emphasizing the potential to develop new treatments for cancer patients worldwide as the Phase I clinical trial nears initiation.

This agreement comes amid a burgeoning interest in ADCs within the biopharmaceutical industry. The ADC market exceeded $10 billion globally last year and is projected to reach $30 billion by 2028. Companies are increasingly investing in this space to capture market share.

Ipsen’s collaboration with Foreseen marks its second significant venture into the ADC domain this year. In April 2024, Ipsen signed a deal worth up to $900 million with Sutro Biopharma. This collaboration grants Ipsen exclusive rights to Sutro’s STRO-003, another ADC that is in the final stages of preclinical development. Ipsen will also manage Phase I preparation activities for STRO-003.

Sutro has indicated that STRO-003 targets the ROR1 tumor antigen, which is overexpressed in various cancer types, including solid tumors and hematological malignancies. This aligns with Ipsen’s broader strategy to expand its oncology pipeline through innovative ADCs.

Ipsen's strategic moves in licensing ADCs are part of a broader trend where biopharma companies are heavily investing in advanced cancer therapies. The ability of ADCs to selectively target and kill cancer cells while minimizing damage to healthy cells makes them highly attractive in the ongoing battle against cancer.

These collaborations underscore Ipsen’s commitment to advancing oncology treatment options and leveraging cutting-edge biotechnological advancements to address unmet medical needs. As the landscape of cancer treatment continues to evolve, Ipsen’s partnerships with Foreseen Biotechnology and Sutro Biopharma place it at the forefront of ADC development, potentially leading to transformative therapies for cancer patients globally.
