time from randomization until one of the following events occurs, whichever comes first: 1. Disease progression (PD) 2. Administration of any additional unplanned anti-lymphoma treatment (except allogeneic or autologous hematopoietic cell transplantations (HCT)) 3. Relapse after achievement of CR 4. Death due to any cause. PD and relapse will be evaluated according to Lugano 2014 criteria (CT-based).

Frequently asked questions about lacutamab

What is lacutamab used for in Peripheral T Cell Lymphoma?

Lacutamab is an investigational monoclonal antibody being studied for the treatment of Peripheral T Cell Lymphoma (PTCL), specifically in patients with relapsed or recurrent disease. It is currently in Phase 2 clinical development for this indication. The drug is being evaluated in patients whose tumors express the KIR3DL2 target.

What does lacutamab target?

Lacutamab targets KIR3DL2, a receptor expressed on malignant T cells in certain types of Peripheral T Cell Lymphoma. As a monoclonal antibody, it is designed to bind to this target on cancer cells. The drug is being studied in biomarker-selected patients whose tumors express KIR3DL2.

Who makes lacutamab?

Lacutamab is being developed by Innate Pharma S.A., a biopharmaceutical company. The company's stock is listed under the ticker IPHA. Innate Pharma is conducting clinical trials of lacutamab in patients with Peripheral T Cell Lymphoma.

What phase is lacutamab in?

Lacutamab is currently in Phase 2 clinical development for Peripheral T Cell Lymphoma. It has received Breakthrough Therapy, Fast Track, and Orphan Drug designations from the FDA. The drug is investigational and has not been approved for any use.

What clinical trials is lacutamab in?

Lacutamab is being studied in two clinical trials. NCT04984837 is a Phase 2 trial in relapsed/recurrent Peripheral T Cell Lymphoma, currently recruiting in Belgium, France, Germany, and Spain. NCT05321147 is a completed Phase 1 trial in relapsed/refractory PTCL expressing KIR3DL2, conducted in the United States and South Korea.

Is lacutamab FDA approved?

Lacutamab is not FDA approved. It is an investigational drug currently in Phase 2 clinical development for Peripheral T Cell Lymphoma. The FDA has granted it Breakthrough Therapy, Fast Track, and Orphan Drug designations, which are intended to expedite development and review of promising therapies.
