Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with stages 1B to IV Mycosis Fungoides or Sézary Syndrome who have received at least one prior treatment.

Probably not a fit

Patients with earlier stages of MF or SS or those who have not received prior treatment may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of combining mogamulizumab with low-dose total skin electron beam therapy (LD-TSEBT) in patients diagnosed with Mycosis Fungoides (MF) and Sézary Syndrome (SS). The primary objective is to assess the efficacy of this combination therapy, while secondary objectives include evaluating additional clinical benefits, safety, and tolerability. Eligible participants must have specific stages of MF or SS and have undergone at least one prior standard treatment. The study is conducted at Stanford Cancer Center in California.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients suffering from advanced skin lymphomas.

How similar studies have gone: While the combination of therapies is being explored, similar approaches have shown promise in treating other forms of cancer, indicating potential for success in this novel application.
