Anaphylaxis is a severe allergic reaction that can occur with the use of certain medications, but it is not listed as a known side effect of Lurbinectedin.

According to DrugPatentWatch [1], Lurbinectedin is currently in clinical trials, and the safety profile of the drug is still being evaluated. However, the source does not provide any information on the incidence of anaphylaxis in these trials.
