**INNATE PHARMA TO HOST ANALYST AND INVESTOR EVENT ON LACUTAMAB ON OCTOBER 28, 2025**

Marseille, France, October 14, 2025, 7:00 AM CEST

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The event will provide clinical perspectives and market outlook for lacutamab, Innate's lead proprietary product progressing towards potential accelerated approval in SS and confirmatory phase 3 initiation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Leading KOL Pierluigi Porcu, M.D., a world expert in T-cell lymphomas, will discuss results from the TELLOMAK Phase 2 trial

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ZS Associates, leading experts in life sciences and healthcare markets, will describe the eligible U.S. CTCL patient population based on real-world claims data

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Innate Pharma's management will provide updates on the planned Phase 3 trial, the regulatory pathway in CTCL, and will outline the commercial opportunity for lacutamab

Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) ("**Innate**" or the "**Company**") today announced that it will host an analyst and investor event focused on lacutamab, an asset with path to potential Accelerated Approval based on existing long-term follow-up data of the Phase 2 TELLOMAK study, providing both clinical perspectives and market outlook. The event will be held in person and virtually on Tuesday, October 28, 2025, from 8:00 a.m. to 10:00 a.m. ET / 1:00 p.m. to 3:00 p.m. CET, at the Park Terrace Hotel on Bryant Park in New York.

The program will feature Pierluigi Porcu, M.D., Division Chief for Hematology and BMT at University of Kentucky, Lexington, a world expert in T-cell lymphomas, who will provide medical perspectives on results from the Phase 2 TELLOMAK trial, which evaluated lacutamab in patients with relapsed or refractory (R/R) cutaneous T-cell lymphoma (CTCL). ZS Associates, leading experts in life sciences and healthcare markets, will describe the eligible U.S. cutaneous T-cell lymphoma patient population based on real-world claims data. Finally, Innate Pharma's management will provide updates on the planned Phase 3 trial, regulatory pathway in CTCL, including path to potential accelerated approval in Sézary syndrome, and commercial opportunity for lacutamab.

"*We look forward to engaging with the investor community in New York to share the latest updates and perspectives on lacutamab, a product which has the potential to meaningfully improve outcomes and quality of life for CTCL patients with high unmet medical needs while creating significant value for shareholders*," said **Jonathan Dickinson, Chief Executive Officer of Innate Pharma**. "*Supported by strong TELLOMAK Phase 2 results, lacutamab is positioned for accelerated approval in Sézary syndrome once the confirmatory study in CTCL is underway. New real-world data showing a larger eligible CTCL population in the U.S. than previously reflected in public data further reinforce our commitment to advancing lacutamab for patients, with the confirmatory Phase 3 protocol nearing completion*."

The event will feature live Q&A opportunities.

**About lacutamab** 

Lacutamab is a first-in-class anti-KIR3DL2 antibody, developed in cutaneous T-cell lymphoma (CTCL) and peripheral T-cell lymphoma (PTCL). CTCL is a group of rare non-Hodgkin lymphomas that develop in the skin and severely affect patients' quality of life. Sezary syndrome (SS) is a rare and aggressive leukemic form with poor survival, while mycosis fungoides (MF) is the most common subtype, with advanced stages associated with poor outcomes.

Data from the Phase 2 TELLOMAK trial in CTCL demonstrated durable activity, a favorable safety profile, and improvements in patients' quality of life. FDA provided encouraging initial feedback on Innate Pharma's proposed regulatory pathway, which could potentially include Accelerated Approval for Sézary syndrome.

The program has received Fast Track designation from the FDA, PRIME designation from the EMA for SS, and Orphan Drug designation in both the US and EU for CTCL. More recently, it has received Breakthrough Therapy Designation for SS.

A Phase 3 in CTCL is under preparation.
