Kyowa Kirin Receives Health Canada Authorization for POTELIGEO® (mogamulizumab for injection)

BEDMINSTER, NJ, June 6, 2022--- Kyowa Kirin, Inc., (Kyowa Kirin, TSE: 4151) today announced that Health Canada has granted a Notice of Compliance to POTELIGEO® (mogamulizumab for injection) for the treatment of adult patients with relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS) after at least one prior systemic therapy. Taken together, MF and SS are the most common subtypes of cutaneous T-cell lymphoma (CTCL),i a rare form of lymphoma that can affect the skin, blood, lymph nodes, and internal organs.ii In Canada, the incidence rate of CTCL, which includes MF and SS among other types, is 11.32 cases per million individuals per year. Approximately 2,500 patients in Canada have been diagnosed with MF while about 110 have been diagnosed with SS.iii

POTELIGEO is a humanized monoclonal antibody (mAb) directed against CC chemokine receptor 4 (CCR4), which is a protein that is highly expressed on the surface of malignant T-cells in all patients with MF and SS, regardless of stage or skin and blood involvement. POTELIGEO was produced using Kyowa Kirin's proprietary POTELLIGENT® technology platform, which is associated with enhanced antibody-dependent cellular cytotoxicity.

Health Canada based its decision on clinical data from the MAVORIC trial, the largest clinical trial to date of a systemic treatment for MF and SS. Published in The Lancet in 2018, the MAVORIC trial was an open-label, international, phase 3, randomized controlled trial which demonstrated that patients in the POTELIGEO study arm met the primary endpoint of significantly prolonged progression-free survival compared with the active comparator treatment arm.iv The most common side effects of POTELIGEO include rash, infusion-related reactions, tiredness, diarrhea, muscle and bone pain, and upper respiratory tract infection. Safety information for POTELIGEO, including contraindications, additional warnings and precautions, adverse reactions and drug interactions is included in the Canadian product monograph.v
