The combination therapy with the cytotoxic T lymphocyte-associated antigen-4 and programmed death 1 antibody-induced asthma in a patient with advanced melanoma.

ABSTRACT

The combination of programmed death 1 (PD-1) inhibitors and cytotoxic T lymphocyte-associated antigen-(CTLA-4) inhibitors have markedly improved the survival of melanoma patients. We report the case of a patient with advanced melanoma who developed asthma during anti-PD-1 and anti-CTLA-4 combination therapy. The patient was a 57-year-old woman enrolled in a clinical trial regarding novel CTLA-4 antibody and sintilimab treatment. The patient was diagnosed with asthma after three cycles of therapy. Subsequently, she was treated with corticosteroids, shortcostero ß2 agonists, and antihistamines. The symptoms were relieved after 7 days. This is the first report of asthma in a patient treated with combination immunotherapy to the best of our knowledge. The mechanism remains to be further explored.
