Ipsen, Sutro Biopharma enter exclusive global licensing agreement for an ADC targeting solid tumours

Overview

Ipsen and Sutro Biopharma announced an exclusive global licensing agreement for STRO-003. STRO-003, an antibody-drug conjugate (ADC) in the final stages of pre-clinical development, targets the ROR1 tumour antigen which is known to be overexpressed in many different cancer types including solid tumours and haematological malignancies. The agreement gives Ipsen exclusive worldwide rights to develop and commercialize STRO-003 and will be the first ADC candidate joining Ipsen’s expanding portfolio.

Words from Ipsen

  • The potential for ADCs in oncology is well-documented and we are excited by the addition of STRO-003, Ipsen’s first ADC candidate with best-in-class potential.” said Mary Jane Hinrichs, SVP and head of early development at Ipsen. 
  • STRO-003 is a next-generation ROR1 ADC, leveraging Sutro’s site-specific technology to generate a highly stable conjugate, coupled with exatecan payloads that have shown significant potential in solid tumours. This is our focus as we prepare to enter phase I, harnessing Ipsen’s global expertise in oncology development, while also reinforcing our commitment to bringing new medicines to patients with few treatment options.”

Words from Sutro

  • We are excited to partner STRO-003 with Ipsen to help us reach more patients faster while retaining significant downstream participation in a medicine in which we believe,” said Jane Chung, president and chief operating officer at Sutro. 
  • Sutro’s research innovation represented in STRO-003 illustrates our leadership in ADC design. We look forward to collaborating with Ipsen’s impressive oncology development team to bring a differentiated ROR1-targeted ADC to patients.”

Antibody-Drug Conjugate

  • ADCs are comprised of three main components: the antibody, payload and linker. The antibody selectively targets an identified tumour antigen, such as ROR1. 
  • Payloads are the pharmaceutically active component to treat the cancer, attached to the antibody via a chemical linker. 
  • The linker connects the antibody and the payload and reduces the amount of payload that reaches non-tumour tissue.

Terms of the Agreement

  • Under the terms of the agreement, Ipsen will assume responsibility for phase I preparation activities, including submission of the Investigational New Drug (IND) application, and all subsequent clinical-development activities and global commercialization activities. 
  • Sutro Biopharma is eligible to receive up to $900 million in potential upfront, development, regulatory and commercial milestone payments including approximately $90 million in near-term payments, including an equity investment, and tiered royalties on global sales, contingent upon successful development and commercialization.
