Resumo

Azathioprine may impair CAR T-cell expansion and persistence, potentially reducing efficacy of tisagenlecleucel. Together they also add to infection risk in patients already immunocompromised.

O que esta interação significa em palavras simples

Azathioprine and Tisagenlecleucel can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Azathioprine belongs to Gastrointestinal Tract; Tisagenlecleucel belongs to Oncology.

Nível de evidência: Low

Por que acontece

Antimetabolite-driven lymphocyte suppression may blunt CAR T-cell proliferation, and the effects add to the immune deficiency caused by the therapy.

O que fazer

Avoid azathioprine around lymphodepletion and CAR T infusion unless essential, and follow the product labeling for washout. Monitor closely for infection and cytopenias if it must be used.
