So the most important toxicity to think about with tagraxofusp is capillary leak syndrome, or CLS. This is kind of unique compared to other chemotherapy drugs. So the most important thing is awareness. So patients need to be closely monitored, especially during the first cycle. Every day we need to monitor their weight, albumin, and other vital signs to make sure they’re not developing CLS. And at any sign of CLS, you hold the drug and you treat with, as appropriate, diuretics, fluid replacement, sometimes even steroids. This is not as big of an issue in second cycle and beyond, which is why second cycle and beyond can be given as an outpatient safely.
