Is this trial a fit for you?

Likely a good fit

Adults aged 19 or older in Korea with a confirmed diagnosis of mycosis fungoides or Sézary syndrome who have received at least one prior systemic therapy and who are being treated with mogamulizumab per the approved indication and consent to data use.

Probably not a fit

Patients with known hypersensitivity to the drug, those using it for non-approved indications, or those who already received the drug in a pre-market clinical trial are excluded and will not be covered by this surveillance.

What this trial studies

This post-marketing surveillance is an all-case investigation conducted under Korean MFDS re-examination requirements to collect real-world data on mogamulizumab (POTELIGEO® Injection 20 mg). It enrolls adults with mycosis fungoides or Sézary syndrome who have received one or more prior systemic therapies and are treated with mogamulizumab under the approved Korean indication. As an observational program, it focuses primarily on safety outcomes with secondary analyses of effectiveness, and it will perform exploratory subgroup analyses including elderly patients, those with renal or hepatic impairment, and patients with prior hematopoietic stem cell transplantation. Participating sites are university hospitals in Korea where data are collected during routine clinical care.

Why it matters

Potential benefit: If successful, this surveillance could confirm real-world safety and effectiveness of mogamulizumab in Korean patients and help clinicians tailor treatment and monitoring.

How similar studies have gone: Previous randomized trials and clinical experience (for example, MAVORIC and subsequent reports) have shown mogamulizumab activity in mycosis fungoides and Sézary syndrome, so this program builds on established evidence.
