A Prospective, US-Based Study Assessing Mogamulizumab-Associated Rash in Patients Diagnosed With Mycosis Fungoides or Sézary Syndrome and Treated With Standard of Care Mogamulizumab
City of Hope Medical Center
Summary
This study is being done to assess mogamulizumab-associated rash in patients diagnosed with mycosis fungoides or sezary syndrome and treated with standard of care mogamulizumab. One of the most common side effects of mogamulizumab is a rash, currently named mogamulizumab-associated rash (MAR) which can look like MF or SS. However, mogamulizumab-associated rash (MAR) does not indicate failure of mogamulizumab, and may be a sign that the drug is working. If not properly evaluated, mogamulizumab-associated rash (MAR) could be misinterpreted as worsening of mycosis fungoides/sezary syndrome, which could lead doctors to recommend stopping mogamulizumab treatment early. The information learned by doing this research study may help tell the difference between mogamulizumab-associated rash (MAR) (sometimes also called "drug eruption") and worsening of the disease. It may also help to uncover information about the cause of mogamulizumab-associated rash (MAR).
Description
PRIMARY OBJECTIVE: I. To assess the incidence of mogamulizumab-associated rash (MAR) and its association with overall response in patients with cutaneous T-cell lymphoma (CTCL); mycosis fungoides \[MF\] and sezary syndrome \[SS\] subtypes) treated with mogamulizumab. OUTLINE: This is an observational study. Patients complete questionnaires, have photographs of their skin taken, and undergo blood sample collection and skin biopsies on study. Patients' medical records are also reviewed.
