Pipeline highlights
IPH4502 (Nectin-4 exatecan ADC):
•IPH4502 is Innate Pharma’s proprietary Nectin-4-targeting ADC, combining a differentiated antibody, a proprietary stable linker and an exatecan payload, with the potential to overcome Enfortumab Vedotin (EV) resistance in urothelial carcinoma (UC) and target tumors with low or heterogeneous Nectin-4 expression beyond UC. IPH4502 is currently being evaluated in a Phase 1 trial in advanced solid tumors known to express Nectin-4 (IPH4502-101; NCT06781983).
•As announced in July 2026 (Link PR), enrollment in the Phase 1 dose-escalation of the IPH4502-101 study is complete, with 76 patients enrolled across multiple solid tumor types.
•Phase 1 dose-escalation data will be presented as a poster at the 38th EORTC-NCI-AACR (ENA) Symposium on Molecular Targets and Cancer Therapeutics, on November 18, 2026 (Barcelona).
•Following the ENA presentation, Innate Pharma will host a hybrid event focused on IPH4502 on November 18, 2026, at 4:00 pm GMT (11:00 am ET) with in-person attendance in London at the IET London, Savoy Place and a live webcast accessible here.
Lacutamab (anti-KIR3DL2 antibody), developed in collaboration with Sobi:
•As announced on August 10, 2026 (Link PR), Innate Pharma entered a strategic partnership with Sobi to license lacutamab in T-cell lymphoma.
•Following closing of the transaction, Innate is advancing TELLOMAK-3, the confirmatory Phase 3 study of lacutamab in Cutaneous T Cell Lymphoma (CTCL), with first patient dosing expected in Q1 2027.
•Phase 3 TELLOMAK-3 includes a confirmatory cohort in Sézary syndrome and a registrational cohort in Mycosis Fungoides.
•Innate plans an FDA filing in H2 2027 for accelerated approval in Sézary syndrome based on the existing Phase 2 TELLOMAK data once the confirmatory Phase 3 study is underway (Link PR).
Monalizumab (anti-NKG2A antibody), developed in collaboration with AstraZeneca:
•Enrollment is complete in the AstraZeneca-sponsored Phase 3 PACIFIC-9 study evaluating durvalumab in combination with monalizumab or oleclumab in patients with unresectable Stage III NSCLC who have not progressed following platinum-based chemoradiation therapy.
•As announced on October 27 (Link PR), AstraZeneca has updated the expected timing for the PACIFIC-9 Phase 3 trial high-level data readout to the first half of 2027, from
the second half of 2026 previously. The revised timing reflects the event-driven nature of the study.
Corporate update
•Frédéric Lombard, Chief Financial Officer, will step down from his position on December 31, 2026, to pursue new career opportunities. The Company thanks him for his contributions and dedication during his time with the Company. The Company has initiated a search of potential candidates to replace Mr. Lombard.
•As of September 30, 2026, the balance available under our April 2023 sales agreement under the At-The-Market program remains at $75 million.
Financial highlights for Q3 2026
Cash, cash equivalents and financial assets of the Company amounted to €96.8 million as of September 30, 2026, which includes the $75 million upfront payment resulting from the closing of the Sobi transaction and the aggregate gross proceeds from the €30 million private placement offering of ordinary shares that occurred in August 2026. Also as of September 30, 2026, financial liabilities amounted to €16.2 million.
Revenues for the first nine months of 2026 amounted to €3.4 million (€2.3 million for the same period in 2025). Revenue from collaboration and licensing agreements mainly results from the partial or entire recognition of the proceeds received pursuant to the co-development and license agreements with AstraZeneca and research collaboration and license agreements with Sanofi.
