The primary outcome was assessed as the number of participants for whom 2.0 x 10e6 CD34+ HSC cells/kg could be collected in 1 or 2 apheresis harvests, after mobilization with MGTA-145 and Plerixafor. The outcome is reported as the number of participants who achieved this level of HSC cells, a number without dispersion.","groups":[{"description":"Patients after screening will undergo baseline evaluation during the premobilization phase up to 30 days before mobilization. Patients will undergo sequential administration of plerixafor 0.24 mg/kg subcutaneously followed 2 hours later by MGTA-145 at 0.03 mg/kg intravenously (3 to10 minute infusion). This will be followed by apheresis. A second day of mobilization and apheresis will be pursued in patients who have not collected 6.0 x 106 CD34+ cells/kg in one session.\n\nMGTA-145: A chemokine receptor type 2 (CXCR2) agonist protein, administered via intravenous (IV) infusion over 3 to 10 minutes.\n\nPlerixafor: An azamacrocycle CXCR4 chemokine receptor antagonist, administered at 0.24 mg/kg subcutaneously, reduced to 0.16 mg/kg in patients with renal dysfunction (per package insert).","id":"OG000","title":"MGTA-145 and Plerixafor HSC Mobilization"}],"paramType":"COUNT_OF_PARTICIPANTS","reportingStatus":"POSTED","timeFrame":"2 days","title":"Number of Participants For Whom 2.0 x 10e6 CD34+ HSC Cells/kg Could be Collected in 1 or 2 Apheresis Harvests","type":"PRIMARY","unitOfMeasure":"Participants"}
