Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients were recruited at multiple dose levels into the Dose Escalation (Phase I) portion of this study to determine the safest dose of this regimen (MTD-Maximum Tolerated Dose). Upon determination of this dose, patients being treated at the MTD proceeded to the Dose Expansion (Phase II) portion of the study and additional patients were recruited
