Clinical Trial Summary

This is an open-label multicenter randomized non comparative phase II study to evaluate the safety and efficacy of the monoclonal anti-KIR3DL2 antibody Lacutamab in patients with Refractory/Relapsing (R/R) KIR3DL2 positive Peripheral T Cell Lymphoma (PTCL) : Not Other Specified (NOS), PTCL-TFH (including Angioimmunoblastic T-cell Lymphoma (AITL), Follicular T-cell lymphoma, Nodal peripheral T-cell lymphoma with TFH phenotype), Anaplastic large cell lymphoma (ALCL), Adult T-cell leukemia/lymphoma (ATL), Hepatosplenic T-cell lymphoma (HSTL), Enteropathy-associated T-cell lymphoma (EATL), Monomorphic epitheliotropic intestinal T cell lymphoma (MEITL), NK-T cell lymphoma (NKT) and Aggressive NK-cell leukemia (ANKL). The design is non comparative meaning that non comparison between arms will be performed as the control arm will ensure that the assumptions used for sample size calculation are verified. For that reason, randomization is unbalanced in favor of the experimental arm (2:1).

laboratory abnormalities prior randomization:

• Calculated creatinine clearance (MDRD or Cockcroft) < 40 mL/min 11. Any significant cardiovascular impairment: New York Heart Association (NYHA) Class III or IV cardiac disease, uncontrolled high blood pressure, unstable angina, myocardial infarction or stroke within the last 6 months from randomization, and cardiac arrhythmia within the last 3 months from randomization 12. Uncontrolled clinically significant intercurrent illness including, but not limited to, diabetes, ongoing active infections. Patients receiving antibiotics for infections that are under control may be included in the study 13. Concurrent malignancy or prior history of malignancies other than lymphoma unless the subject has been free of disease for = 2 years, except early stage cutaneous squamous or basal cell carcinoma, localized prostate cancer, or cervical intraepithelial neoplasia 14. Major surgery within 4 weeks before randomization

15. Pregnant or lactating females
