The US Food and Drug Administration (FDA) has granted breakthrough therapy designation to mogamulizumab for the treatment of adults with cutaneous T-cell lymphoma (CTCL) who have received at least 1 prior systemic therapy.
Mogamulizumab is a humanized monoclonal antibody directed against CCR4. It is being developed by Kyowa Hakko Kirin Co., Ltd.
The breakthrough designation for mogamulizumab in CTCL is based on data from the phase 3 MAVORIC study, the largest randomized trial in CTCL.
In MAVORIC, researchers are comparing mogamulizumab and vorinostat in patients with CTCL (both mycosis fungoides and Sézary syndrome) who have failed at least 1 prior systemic treatment.
In April, Kyowa Hakko Kirin announced results from this trial, which showed that patients treated with mogamulizumab have significantly better progression-free survival than patients treated with vorinostat. The company also said mogamulizumab has a tolerable safety profile.
Kyowa Hakko Kirin has not provided any data from MAVORIC but is working with investigators on the future presentation and publication of results from this trial.
Results of a phase 1/2 study of mogamulizumab in previously treated CTCL patients were published in Blood in March 2015.
About breakthrough designation
The FDA’s breakthrough designation is intended to expedite the development and review of new treatments for serious or life-threatening conditions.
The designation entitles the company developing a therapy to more intensive FDA guidance on an efficient and accelerated development program, as well as eligibility for other actions to expedite FDA review, such as rolling submission and priority review.
To earn breakthrough designation, a treatment must show encouraging early clinical results demonstrating substantial improvement over available therapies with regard to a clinically significant endpoint, or it must fulfill an unmet need.
