Innate Pharma SA to Present MATISSE Phase 2 Interim Results of IPH5201 in Clinical Trials Plenary Session at AACR 2026 Innate Pharma SA announced that interim results from the MATISSE Phase 2 study evaluating IPH5201 in combination with durvalumab and platinum-based chemotherapy in resectable non-small cell lung cancer (NSCLC) will be presented in one of the Clinical Trials Plenary Sessions at the American Association for Cancer Research (AACR) Annual Meeting 2026, taking place April 17–22, 2026 in San Diego, California. The MATISSE study (NCT05742607) is a single arm Phase 2 clinical trial evaluating perioperative IPH5201, an anti-CD39 blocking antibody, in combination with perioperative durvalumab (anti-PD-L1) in addition to neoadjuvant platinum-based chemotherapy in previously untreated patients with resectable NSCLC. The trial is designed to assess whether dual inhibition of the CD39 and PD-L1 pathways, together with chemotherapy, can enhance anti-tumor immune responses and improve clinical outcomes in early-stage lung cancer. These results follow a pre-planned interim analysis on 40 patients. The combination of IPH5201 with durvalumab and chemotherapy demonstrated higher pathological complete response (pCR) rates compared with the benchmark set by durvalumab plus chemotherapy alone. Notably, pCR was 35.7% and 50% in patients with tumors expressing PD-L1 =1% and PD-L1 =50%, respectively. Based on these results, the study continues to recruit patients with tumors expressing PD-L1=1%. The presentation will be available in the publication section of Innate Pharma’s website. Abstract details: Dual CD39 and PD-L1 inhibition: Interim results from the Phase 2 MATISSE trial of IPH5201 plus durvalumab and platinum-based chemotherapy in patients with resectable NSCLC. Abstract Code: CT231. Session: CTPL04 – Advances in Immunotherapy. Session Date/Time: Tuesday, April 21, 2026, 10:45 – 11:00 AM PDT. IPH5201 is a first-in-class monoclonal antibody targeting CD39, a key immunosuppressive enzyme in the adenosine pathway. CD39 is expressed on tumor-infiltrating immune and stromal cells and contributes to immunosuppression by degrading extracellular adenosine triphosphate (ATP) into adenosine monophosphate (AMP), which is then further degraded into adenosine by CD73. By blocking CD39, IPH5201 promotes the accumulation of immunostimulatory ATP and reduces the production of immunosuppressive adenosine, thereby enhancing anti-tumor immune responses. IPH5201 is being co-developed in collaboration with AstraZeneca and is currently being evaluated in the Phase 2 MATISSE trial (NCT05742607), a multicenter study investigating perioperative treatment with IPH5201 in combination with durvalumab (anti-PD-L1) and platinum-based chemotherapy in patients with resectable non-small cell lung cancer (NSCLC). The MATISSE trial is designed to assess anti-tumor activity, including pathological complete response, and safety, with the goal of determining whether dual inhibition of the CD39 and PD-L1 pathways, in combination with chemotherapy, can enhance anti-tumor immunity and improve clinical outcomes in early-stage NSCLC.

Innate Pharma SA Highlights Preclinical Anti-Tumor Efficacy Data of its Antibody Drug Conjugate IPH4502 at AACR Annual Meeting Innate Pharma SA shared new preclinical data for IPH4502, its novel and differentiated topoisomerase I inhibitor Antibody Drug Conjugate (ADC) targeting Nectin-4. The data were presented at the American Association for Cancer Research (AACR) Annual Meeting 2025. Nectin-4 targeting is validated by enfortumab vedotin (EV), an ADC with a monomethyl auristatin E (MMAE) payload, approved for urothelial carcinoma (UC), an indication with high Nectin-4 expression. However, EV discontinuation due to toxicity, disease relapse, or treatment ineligibility, along with its limited efficacy in tumors with lower Nectin-4 expression, underscores the need for a differentiated Nectin-4 ADC with improved therapeutic window and improved mechanisms of action. IPH4502 is currently investigated in a Phase 1 trial in advanced solid tumors. The Phase 1 trial will assess the safety, tolerability, and preliminary efficacy of IPH4502 in different solid tumors known to express Nectin-4, including but not limited to urothelial carcinoma, non-small cell lung, breast, ovarian, gastric, esophageal, and colorectal cancers. The study plans to enroll approximately 105 patients. In preclinical models, IPH4502 demonstrates strong bystander killing effect, and efficient internalization, enabling a potent anti-tumor activity in models with various Nectin-4 expression levels. Additionally, IPH4502 shows efficacy in models resistant to MMAE-ADC. These results support its potential for development beyond UC and in cancer patients treated with MMAE-based ADCs.

In a recent update to the Olsen 2011 guidelines, it was clarified that the pathological assessment of lymph nodes be limited to those that satisfy nodal lymphoma i.e. N3 designation. Based on these criteria, results showed that lacutamab produced an increased global objective response rate (ORR) of 42.9% (95% confidence interval [CI], 24.5-63.5) in patients with KIR3DL2 = 1% MF (cohort 2, n=21), including 2 complete responses and 7 partial responses. Clinical Benefit Rate remained unchanged at 85.7% [95% CI tbc]. In Cohort 3, comprising 18 patients with KIR3DL2 < 1% MF, findings remain unchanged. Lacutamab is a first-in-class anti-KIR3DL2 humanized cytotoxicity-inducing antibody that is currently in clinical trials for treatment of cutaneous T-cell lymphoma (CTCL), an orphan disease, and peripheral T cell lymphoma (PTCL). Rare cutaneous lymphomas of T lymphocytes have a poor prognosis with few efficacious and safe therapeutic options at advanced stages. KIR3DL2 is an inhibitory receptor of the KIR family, expressed by approximately 65% of patients across all CTCL subtypes and expressed by up 90% of patients with certain aggressive CTCL subtypes, in particular, Sézary syndrome. It is expressed by up to 50% of patients with mycosis fungoides and peripheral T-cell lymphoma (PTCL). It has a restricted expression on normal tissues. Lacutamab is granted European Medicines Agency (EMA) PRIME designation and US Food and Drug Administration (FDA) granted Fast Track designation for the treatment of patients with relapsed or refractory Sézary syndrome who have received at least two prior systemic therapies. Lacutamab is granted orphan drug status in the European Union and in the United States for the treatment of CTCL. Announcement • Jul 12

Innate Pharma SA Announces Publication of Preclinical Data with a Trifunctional NK Cell Engager in Acute Myeloid Leukemia in Nature Biotechnology Innate Pharma SA announced the publication in Nature Biotechnology of preclinical data showing the control of acute myeloid leukemia (AML) cells by a trifunctional NKp46-CD16a-NK cell engager (NKCE) targeting CD123. The studies were conducted by Innate and Sanofi and published in Nature Biotechnology on January 12, 2023. The study shows that expression of CD64 on AML blasts confers resistance to anti-CD123 antibody-dependent cell cytotoxicity (ADCC) and redirecting NK cells against cancer targets through binding to CD16a and NKp46 circumvents this resistance. Moreover, through their binding to NKp46, CD123-NKCE specifically target NK cells and has potent antitumor activity against primary AML blasts; it induces NK cell activation and cytokine secretion only in the presence of AML cells. In vivo, its antitumor activity in a mouse tumor model exceeds that of the comparator anti-CD123 antibody. The efficacy of CD123-NKCE in vitro in human peripheral blood mononuclear cells and in vivo in nonhuman primates was associated with the induction of low pro-inflammatory cytokine release and no signs of toxicity. These results support clinical development of CD123-NKCE. A Phase 1/2 clinical trial by Sanofi is ongoing, evaluating IPH6101/SAR’579 (SAR443579), the first NKp46/CD16-based CD123-targeted ANKET NK cell engager, in patients with relapsed or refractory acute myeloid leukemia (R/R AML), B-cell acute lymphoblastic leukemia (B-ALL) or high-risk myelodysplastic syndrome (HR-MDS).
