MARSEILLE, France–(BUSINESS WIRE)–#immunotherapy–Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced positive final results from the Phase 2 TELLOMAK study in Sézary Syndrome (SS). The results were presented at the ASH 2023 Annual Meeting, in San Diego, California.


As of May 1, 2023, data cutoff, patients in the Sézary Syndrome cohort (cohort 1, n=56) received a median of 5 prior systemic therapies, including mogamulizumab, and had a median follow-up of 14.4 months.

The data demonstrated that lacutamab showed robust clinical activity and an overall favorable safety profile. The global confirmed objective response rate (ORR) was 37.5% (21/56), including 2 complete responses (CR) and 19 partial responses (PR). Overall response rate (ORR) in the skin was 46.4% (26/56), including 5 CR and 21 PR and ORR in the blood was 48.2% (27/56) with 15 CR and 12 PR. Median progression-free survival was 8.0 months (95% CI 4.7-21.2). In patients who achieved a global response, the median duration of response is 12.3 months (95% CI 5.2-NE).

The rapid and durable responses observed in the Phase 2 TELLOMAK trial which enrolled heavily pretreated patients, confirms that treatment with lacutamab achieves clinically meaningful outcomes for patients with Sézary Syndrome after at least two prior systemic therapies,” commented Dr. Sonia Quaratino, Chief Medical Officer of Innate Pharma.Enrollment to TELLOMAK study is completed and long-term follow-up will provide more mature data on the key study endpoints in due course.”

Prof. Pierluigi Porcu, Director, Division of Hematologic Malignancies and Hematopoietic Stem Cell Transplantation, Sidney Kimmel Cancer Center, Jefferson Health, Philadelphia, and Principal Investigator in the TELLOMAK study, added: “Sézary Syndrome patients treated with more than two prior systemic therapies including mogamulizumab, represent a high unmet medical need population with poor quality of life. It is promising to see lacutamab achieving remarkable efficacy along with favorable safety in this heavily pre-treated population. We thank the investigators, clinical research coordinators, patients and caregivers involved in the TELLOMAK program.”

Innate Pharma will host a virtual KOL event, featuring Prof. Pierluigi Porcu, on lacutamab, highlighting results from ASH oral presentation on Tuesday, December 12, 2023 at 7:00AM PST (4:00PM CET).

About Lacutamab

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.

About TELLOMAK

TELLOMAK (NCT03902184) is a global, open-label, multi-cohort Phase 2 clinical trial recruiting patients with Sézary syndrome and mycosis fungoides (MF) in the United States and Europe. Specifically:

  • Cohort 1: lacutamab being evaluated as a single agent in approximately 60 patients with Sézary syndrome who have received at least two prior systemic therapies, including mogamulizumab. The Sézary syndrome cohort of the study could enable the registration of lacutamab in this indication.
  • Cohort 2: lacutamab being evaluated as a single agent in patients with MF that express KIR3DL2, as determined at baseline with a Simon 2-stage design.
  • Cohort 3: lacutamab being evaluated as a single agent in patients with MF that do not express KIR3DL2, as determined at baseline, with a Simon-2 stage design.
  • All comers: lacutamab being evaluated as a single agent in patients with both KIR3DL2 expressing and non-expressing MF to explore the correlation between the level of KIR3DL2 expression and treatment outcomes utilizing a formalin-fixed paraffin embedded (FFPE) assay under development as a companion diagnostic.

The trial is now fully enrolled. The primary endpoint of the trial is objective global response rate. Key secondary endpoints are progression-free survival, duration of response, overall survival, quality of life, pharmacokinetics and immunogenicity and adverse events.
