Ipsen and Sutro Biopharma announce exclusive global licensing agreement for an ADC targeting solid tumors
PARIS, FRANCE; SAN FRANCISCO, U.S., 02 April 2024 - Ipsen (Euronext: IPN; ADR: IPSEY) and Sutro Biopharma (NASDAQ: STRO, “Sutro”, “the Company”) today 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 tumor antigen which is known to be overexpressed in many different cancer types including solid tumors and hematological malignancies. iThe agreement gives Ipsen exclusive worldwide rights to develop and commercialize STRO-003 and will be the first ADC candidate joining Ipsen’s expanding portfolio.
“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 tumors. 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.”
“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.”
ADCs are comprised of three main components: the antibody, payload and linker. The antibody selectively targets an identified tumor 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-tumor tissue.ii
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 $900m in potential upfront, development, regulatory and commercial milestone payments including approximately $90m in near-term payments, including an equity investment, and tiered royalties on global sales, contingent upon successful development and commercialization.

Ipsen Disclaimers and/or Forward-Looking Statements
The forward-looking statements, objectives and targets contained herein are based on Ipsen’s management strategy, current views and assumptions. Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. All of the above risks could affect Ipsen’s future ability to achieve its financial targets, which were set assuming reasonable macroeconomic conditions based on the information available today. Use of the words ‘believes’, ‘anticipates’ and ‘expects’ and similar expressions are intended to identify forward-looking statements, including Ipsen’s expectations regarding future events,
2
including regulatory filings and determinations. Moreover, the targets described in this document were prepared without taking into account external-growth assumptions and potential future acquisitions, which may alter these parameters. These objectives are based on data and assumptions regarded as reasonable by Ipsen. These targets depend on conditions or facts likely to happen in the future, and not exclusively on historical data. Actual results may depart significantly from these targets given the occurrence of certain risks and uncertainties, notably the fact that a promising medicine in early development phase or clinical trial may end up never being launched on the market or reaching its commercial targets, notably for regulatory or competition reasons. Ipsen must face or might face competition from generic medicine that might translate into a loss of market share. Furthermore, the research and development process involves several stages each of which involves the substantial risk that Ipsen may fail to achieve its objectives and be forced to abandon its efforts with regards to a medicine in which it has invested significant sums. Therefore, Ipsen cannot be certain that favorable results obtained during preclinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the medicine concerned. There can be no guarantees a medicine will receive the necessary regulatory approvals or that the medicine will prove to be commercially successful. If underlying assumptions prove inaccurate or risks or uncertainties materialize, actual results may differ materially from those set forth in the forward-looking statements. Other risks and uncertainties include but are not limited to, general industry conditions and competition; general economic factors, including interest rate and currency exchange rate fluctuations; the impact of pharmaceutical industry regulation and healthcare legislation; global trends toward healthcare cost containment; technological advances, new medicine and patents attained by competitors; challenges inherent in new-medicine development, including obtaining regulatory approval; Ipsen’s ability to accurately predict future market conditions; manufacturing difficulties or delays; financial instability of international economies and sovereign risk; dependence on the effectiveness of Ipsen’s patents and other protections for innovative medicines; and the exposure to litigation, including patent litigation, and/or regulatory actions. Ipsen also depends on third parties to develop and market some of its medicines which could potentially generate substantial royalties; these partners could behave in such ways which could cause damage to Ipsen’s activities and financial results. Ipsen cannot be certain that its partners will fulfil their obligations. It might be unable to obtain any benefit from those agreements. A default by any of Ipsen’s partners could generate lower revenues than expected. Such situations could have a negative impact on Ipsen’s business, financial position or performance. Ipsen expressly disclaims any obligation or undertaking to update or revise any forward-looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law. Ipsen’s business is subject to the risk factors outlined in its registration documents filed with the French Autorité des Marchés Financiers. The risks and uncertainties set out are not exhaustive and the reader is advised to refer to Ipsen’s latest Universal Registration Document, available on ipsen.com.

Company’s ability to fund development activities and achieve development goals, the Company’s ability to protect intellectual property, the value of the Company’s holdings of Vaxcyte common stock, and the Company’s commercial collaborations with third parties and other risks and uncertainties described under the heading “Risk Factors” in documents the Company files from time to time with the Securities and Exchange Commission.
