Per journal article "engraftment after autologous hematopoietic stem cell transplantation in patients mobilized with plerixafor: a retrospective, multicenter study of a large series of patients".By, antelo, m.L., altuna, a., gimeno, j.J., ferreiro, j.J., amunárriz, c., mateos, j.J., zalba, s., alkorta, a., rifón, j., arroyo, j.L., uresandi, a., moreno, j.A., nájera, m.J., pinzón, s., garcía, a., vallejo, j.C.Abstract plerixafor (plx) appears to effectively enhance hematopoietic stem-cell mobilization prior to autologous hematopoietic stem cell transplantation (auto-hct).However, the quality of engraftment following auto-hct has been little explored.Here, engraftment following auto-hct was assessed in patients mobilized with plx through a retrospective, multicenter study of 285 consecutive patients.Information on early and 100-day post-transplant engraftment was gathered from the 245 patients that underwent auto-hct.The median number of plx days to reach the stem cell collection goal (=2 × 106 cd34+ cells/kg) was 1 (range 1¿4) and the median plx administration time before apheresis was 11 h (range 1¿18).The median number of apheresis sessions to achieve the collection goal was 2 (range 1¿5) and the mean number of cd34+ cells collected was 2.95 × 106/kg (range 0¿30.5).Plx administration was safe, with only 2 mild and transient gastrointestinal adverse events reported.The median time to achieve an absolute neutrophil count (anc) >500/¿l was 11 days (range 3¿31) and the median time to platelet recovery >20 × 103/¿l was 13 days (range 5¿69).At 100 days after auto-hct, the platelet count was 137 × 109/l (range 7¿340), the anc was 2.3 × 109/l (range 0.1¿13.0), and the hemoglobin concentration was 123 g/l (range 79¿165).Plx use allowed auto-hct to be performed in a high percentage of poorly mobilized patients, resulting in optimal medium-term engraftment in the majority of patients in whom mobilization failed, in this case mainly due to suboptimal peripheral blood cd34+ cell concentration on day +4 or low cd34+ cell yield on apheresis potential adverse event : in our series, there were 15 patients who had already received 1 previous auto-hct (15 mm & 1 lymphoma) and one patient who had received 2 previous auto-hct (mm).The median cd34 +/ kg obtained in this subgroup of patients was 2.8 ×106 cd34 / kg and the median number of apheresis sessions required was 2 per patient.Among the 285 patients, only 2 (0.8 %) reported aes following plx administration, including one case of abdominal discomfort and one case of diarrhea.Both these aes were mild and transient, and as such, plx was well tolerated in accordance with the established safety profile of the drug specific details, such as patient information and outcome, were not included in the article for these events, therefore this report is being provided as a summary of the events.It is unknown at this time if medical intervention was required for these events the collection set is not available for return because it was discarded by the customer.

This report is being filed to provide additional information in h.6 and h.11 investigation: lot number, manufacture and expiry date are not available at this time.Further evaluation of this event has determined that the device did not cause or contribute to a death or serious injury, nor is there a likely potential for death or serious injury associated with this event based on additional investigational information.It was confirmed that the ae reactions were plx-related and were mild, with no medical intervention required and the death was due to transplant related mortality (neutropenic infection).There is no direct allegation against the tbct devices.No further reporting will be provided as this does not represent a reportable event.Citation: antelo, m.L., altuna, a., gimeno, j.J., ferreiro, j.J., amunárriz, c., mateos, j.J., zalba, s., alkorta, a., rifón, j., arroyo, j.L., uresandi, a., moreno, j.A., nájera, m.J., pinzón, s., garcía, a., & vallejo, j.C.(2021).Engraftment after autologous hematopoietic stem cell transplantation in patients mobilized with plerixafor: a retrospective, multicenter study of a large series of patients.Transfusion and apheresis science, 60(3), 103130.Https://doi.Org/10.1016/j.Transci.2021.103130.
