HLA-DRB1*04:05 in two cases of Vogt-Koyanagi-Harada disease-like uveitis developing from an advanced melanoma patient treated by sequential administration of nivolumab and dabrafenib/trametinib therapy

摘要

Although uveitis is reported as a rare adverse event (AE) associated with dabrafenib/trametinib therapy or nivolumab, the occurrence of severe uveitis is extremely rare. We describe two cases of Vogt-Koyanagi-Harada (VKH)-like uveitis developing after the sequential administration of nivolumab and dabrafenib/trametinib therapy. Interestingly, both cases had HLA-DRB1*04:05, which is strongly associated with VKH disease, and achieved biologically complete remission after the treatment for uveitis. Our cases suggest a possible correlation between VKH-like uveitis as an AE and the clinical outcomes of sequential administration of nivolumab and dabrafenib/trametinib therapy for the treatment of advanced melanoma.
