With a median follow-up of 30.2 months, patients with EMD (n = 34) had significantly worse progression-free survival (PFS) and overall survival (OS) than those with bone marrow-only disease (n = 75): PFS was 24.2 months vs. 9.0 months (HR 2.15, 95% CI 1.31-3.54), and OS was not reached vs. 24.0 months (HR 3.79, 95% CI 1.81-7.94). In contrast, patients with PSD did not experience significantly shorter PFS or OS. Among patients with EMD, those with high extramedullary tumor burden had a lower overall response rate (ORR). For extramedullary tumor burden <25 cm<sup>2</sup>, 25-50 cm<sup>2</sup>, and >50 cm<sup>2</sup>, ORR was 81.0% (66.7% complete response, CR), 83.3% (50% CR), and 57.1% (0% CR), respectively. Importantly, EMD-positive relapses post-CAR T cell therapy comprised half of all relapses observed.

Busulphan metabolites were detectable in plasma and urine up to 72-h after the last Bu-dose. Sulfolane levels were high and reached maximum concentration at the time-point reported for the convulsions' occurrence. Mice were treated with either busulphan or one of its metabolites, separately. Sulfolane treated-mice showed the highest brain exposure (AUC<sub>brain</sub>/AUC<sub>plasma</sub>). Seizures and hypothermia were observed after sulfolane administration, accompanied with a significant decrease in calbindin-28k concentrations in the brain. Behavior changes but no signs of convulsions were seen in mice treated with lower sulfolane doses. Moreover, a reduction of spontaneous events during whole-cell patch clamp recordings from pyramidal neurons was observed following bath application of sulfolane. In conclusion, these are the first results showing that sulfolane is the major cause of seizures and hypothermia. Sulfolane concentration in plasma mirrors its concentration in the brain.
