Ipsen (ipsen.com) announced today that the U.S. Food and Drug Administration (FDA) (fda.gov) has granted Breakthrough Therapy Designation (BTD) for IPN60340 in combination with venetoclax and azacitidine (Ven-Aza) in first line unfit acute myeloid leukemia, an aggressive blood cancer affecting older adults. IPN60340 is an investigational first-in-class monoclonal antibody targeting BTN3A, a key immune-regulatory molecule broadly expressed across cancer. Breakthrough Therapy Designation is intended to expedite the development and review of medicines for serious or life-threatening conditions with evidence of a substantial clinical improvement. IPN60340 previously received Orphan Drug Designations from the U.S. Food and Drug Administration and European Medicines Agency in July 2025.
“This Breakthrough Therapy Designation recognizes both the urgent need for new treatment options for people living with acute myeloid leukemia and the promising data seen so far in the development program for IPN60340,” said Christelle Huguet, PhD, EVP and Head of R&D, Ipsen. “We look forward to working closely with the FDA as we advance to the next stage of clinical development and continue to deliver medicines with the potential to be transformative to people living with cancer.”
This Breakthrough Therapy Designation is based on data from the Phase I/II EVICTION trial. Updated clinical data orally presented at the American Society of Hematology (n=57)1 from the EVICTION trial showed treatment with IPN60340 in combination with Ven-Aza achieved very encouraging high responses. In this single-arm trial, treatment with IPN60340 and Ven-Aza (n=38), resulted in a near doubling of the complete response relative to those seen in historical standard of care data across all molecular subtypes in newly diagnosed patients including sub-types typically less responsive to standard of care (Ven-Aza).1,2 IPN60340 in combination with Ven-Aza was also shown to be well tolerated, underscoring IPN60340’s potential as a novel immunotherapy to improve outcomes for patients with AML. Based on these preliminary data, we look forward to discussing the design of the Phase II/III development plans with the FDA for IPN60340 in H1 2026.
About the EVICTION trial
EVICTION is a first-in-human, dose-escalation (Part 1) and cohort-expansion (Part 2) clinical trial of IPN60340 (ICT01) in patients with various advanced relapsed or refractory solid or hematologic cancers that have exhausted standard-of-care treatment options, as well as newly-diagnosed AML. More information on the EVICTION trial can be found at clinicaltrials.gov (NCT04243499).
About IPN60340 (ICT01)
IPN60340 is a humanized, anti-BTN3A (also known as CD277) monoclonal antibody that promotes the recognition and elimination of tumor cells by γ9δ2 T cells, which are responsible for immunosurveillance of malignancy and infections. The three isoforms of BTN3A targeted by IPN60340 are overexpressed on many solid tumors (e.g., melanoma, urothelial cell, colorectal, ovarian, pancreatic, and lung cancer) and hematologic malignancies (e.g., leukemia and lymphomas) and are also expressed on the surface of innate (e.g., γδ T cells and NK cells) and adaptive immune cells (T cells and B cells). Binding to BTN3A is essential for the activation of the anti-tumor immune response of γ9δ2 T cells. By altering the conformation of BTN3A, IPN60340 promotes this binding, thereby selectively activating circulating γ9δ2 T cells. This leads to migration of γ9δ2 T cells out of the circulation and into the tumor tissue, and triggers a downstream immunological cascade through secretion of pro-inflammatory cytokines, including but not limited to IFNγ and TNFα, further augmenting the anti-tumor immune response. Anti-tumor activity and efficacy of IPN60340 have been shown in patients across several cancer indications. IPN60340 is an investigational therapy under evaluation for people 75 years or older living with acute myeloid leukemia who due to comorbidities are prevented from receiving treatment with intensive chemotherapy.

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, 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.
