argenx, a clinical-stage biotechnology company has announced an exclusive, global collaboration and license agreement for with Cilag GmbH International, an affiliate of the Janssen Pharmaceutical Companies of Johnson & Johnson.  

Cusatuzumab (ARGX-110) is a highly differentiated anti-CD70 SIMPLE AntibodyÔ.

Cusatuzumab is currently in development in a Phase 1/2 combination study with Vidaza® for newly diagnosed, elderly patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) who are unfit for chemotherapy.

Tim Van Hauwermeiren, CEO of argenx said, “AML continues to be an aggressive and deadly cancer of the blood and bone marrow with very high relapse rates. Cusatuzumab offers a novel mode of action targeting leukemic stem cells, which are a known driver of the relapse mechanism, and has shown a compelling response rate and tolerability profile to date.”

“Janssen is an ideal strategic partner for us to develop this differentiated investigational therapy given its extensive clinical, regulatory and commercial expertise in oncology, and we believe that through this collaboration we are best positioned to reach the broadest number of patients as quickly as possible. The collaboration also strengthens our financial position, enabling our growth into a fully-integrated organization as we continue to exploit our deep pipeline of wholly-owned product candidates, including our lead product candidate efgartigimod which we are evaluating in four severe autoimmune indications”, he added.

argenx and Janssen have agreed to a joint global clinical development plan to evaluate cusatuzumab in AML, MDS and other potential future indications.

Under the terms of the agreement, Janssen will pay argenx $300 million in an upfront payment and JJDC will purchase $200 million (1,766,899) of newly issued shares representing 4.68% of argenx’s outstanding shares at a price of €100.02 per share ($113.19).

argenx will be eligible to receive potentially up to $1.3 billion in development, regulatory and sales milestones, in addition to tiered, double-digit royalties. Janssen will be responsible for commercialization worldwide. argenx retains the option to participate in commercialization efforts in the U.S., where the companies have agreed to share economics 50/50 on a royalty basis and outside the U.S., Janssen will pay double-digit sales royalties to argenx.
