Safety is paramount in this Phase I study and therefore if there was no effusion and/or if it was not safe to sample based on investigator judgement, no samples could be obtained, and no PKs could be obtained to answer this objective. There is no data collected for this measure of effusion PKs.","reportingStatus":"POSTED","timeFrame":"Cycle 1 Day 1(C1D1), C1D7, C6D1 (one cycle = 21 days)","title":"Pharmacokinetics of Lenalidomide Effusion","type":"SECONDARY","unitOfMeasure":"Ng/mL"}
