Kyowa Kirin Presents Additional Analyses of MAVORIC Trial

TOKYO, Dec. 3, 2018 /PRNewswire/ -- Kyowa Hakko Kirin Co., Ltd., (Kyowa Kirin) announces that additional data from the MAVORIC trial (Mogamulizumab anti-CCR4 Antibody Versus ComparatOR In CTCL) will be presented at the 60(th) Annual Meeting of the American Society of Hematology (ASH), held in San Diego, California, on December 1-4.(1)(,2,3) Mogamulizumab is approved in the United States (U.S.) for the treatment of adult patients with relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS) after at least one prior systemic therapy. MF and SS are the most common subtypes of cutaneous T-cell lymphoma (CTCL).(4)

Three Kyowa Kirin-sponsored posters featuring post-hoc analyses of the pivotal MAVORIC study will be presented during the ASH meeting. MAVORIC is the first pivotal trial to use progression free survival (PFS) as a primary endpoint and the largest randomized study to compare systemic therapies in CTCL.(5) Secondary endpoints included proportion of patients achieving an overall response rate (ORR), duration of response (DOR) and safety.(5)

"Mycosis fungoides and Sézary syndrome may have a severe impact on patients, yet may be indolent in nature, making it challenging for both patients and physicians to control the diseases over decades," said Jeffrey S. Humphrey, M.D., President of Kyowa Kirin Development. "These additional analyses of MAVORIC provide further insight into these rare and serious diseases."

The studies being presented at ASH include:

    --  Abstract #3592: Evaluation of Symptom and Side Effect Bother in
        Cutaneous T-Cell Lymphoma Patients Treated with Mogamulizumab or
        Vorinostat (Hudgens S, Porcu P, Quaglino P, et al)(1)
    --  Abstract #2910: Long-Term Clinical Benefit to Anti-CCR4 Mogamulizumab:
        Results from the Phase 3 MAVORIC Study in Previously Treated Cutaneous
        T-Cell Lymphoma (CTCL) (Bagot M, Dalle S, Sokol L, et al)(2)
    --  Abstract #1619: Efficacy of Mogamulizumab By Prior Systemic Therapy in
        Patients with Previously Treated Cutaneous T-Cell Lymphoma: Post Hoc
        Analysis from the Phase 3 MAVORIC Study (Zinzani, P, Horwitz S, Kim Y,
        et al)(3)

Please see Poteligeo indication and Important Safety Information below.

INDICATION
POTELIGEO(®) (mogamulizumab-kpkc) injection, for intravenous infusion is indicated for the treatment of adult patients with relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS) after at least one prior systemic therapy.

Important Safety Information

Warnings and Precautions:

    --  Dermatologic toxicity: Monitor patients for rash throughout the course
        of treatment. For patients who experienced dermatologic toxicity in
        Trial 1, the median time to onset was 15 weeks, with 25% of cases
        occurring after 31 weeks. Interrupt POTELIGEO for moderate or severe
        rash (Grades 2 or 3). Permanently discontinue POTELIGEO for
        life-threatening (Grade 4) rash or for any Stevens-Johnson syndrome
        (SJS) or toxic epidermal necrolysis (TEN).

    --  Infusion reactions: Most infusion reactions occur during or shortly
        after the first infusion. Infusion reactions can also occur with
        subsequent infusions. Monitor patients closely for signs and symptoms of
        infusion reactions and interrupt the infusion for any grade reaction and
        treat promptly. Permanently discontinue POTELIGEO for any
        life-threatening (Grade 4) infusion reaction.

    --  Infections: Monitor patients for signs and symptoms of infection and
        treat promptly.

    --  Autoimmune complications: Interrupt or permanently discontinue POTELIGEO
        as appropriate for suspected immune-mediated adverse reactions. Consider
        the benefit/risk of POTELIGEO in patients with a history of autoimmune
        disease.

    --  Complications of allogeneic HSCT after POTELIGEO: Increased risks of
        transplant complications have been reported in patients who received
        allogeneic HSCT after POTELIGEO. Follow patients closely for early
        evidence of transplant-related complications.

Adverse Reactions:

    --  The most common adverse reactions (reported in >= 10% of patients) with
        POTELIGEO in the clinical trial were rash, including drug eruption
        (35%), infusion reaction (33%), fatigue (31%), diarrhea (28%), drug
        eruption (24%), upper respiratory tract infection (22%), musculoskeletal
        pain (22%), skin infection (19%), pyrexia (17%), edema (16%), nausea
        (16%), headache (14%), thrombocytopenia (14%), constipation (13%),
        anemia (12%), mucositis (12%), cough (11%), and hypertension (10%).

You are encouraged to report suspected adverse reactions to Kyowa Kirin, Inc. at 1-844-768-3544 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

About mogamulizumab
Mogamulizumab is a humanized monoclonal antibody (mAb) directed against CC chemokine receptor 4 (CCR4), which is frequently expressed on leukemic cells of certain hematologic malignancies including CTCL (cutaneous T-cell lymphoma).(6)

About mycosis fungoides (MF) and Sézary Syndrome (SS)
MF and SS are the two most common subtypes of CTCL, a rare type of non-Hodgkin's lymphoma, which is characterized by localization of malignant T lymphocytes to the skin, and depending on the stage, the disease may involve skin, blood, lymph nodes, and viscera.(5)

About MAVORIC
MAVORIC is a Phase 3 open-label, multi-center, randomized study of mogamulizumab versus vorinostat in patients with MF and SS who have failed at least one prior systemic treatment.(5) The study was conducted in the U.S., Europe, Japan and Australia, and randomized 372 patients to receive either mogamulizumab or vorinostat.(5)
