What was measured

Concentration of daratumumab in CSF was reported. '0' in the number analyzed field signifies that none of the participants were available for the analysis at the specified time points.

Analysis population: The CSF PK evaluable analysis set included all enrolled participants who received at least 1 dose of daratumumab and provided at least 1 post-infusion CSF sample for daratumumab concentrations. Here, 'N' (number of participants analyzed) signifies number of participants who were evaluable for this outcome measure and 'n' (number analyzed) represent number of participants evaluable for specified timepoints.
