Abstract
Autologous chimeric antigen receptor-modified T-cells (CAR-T) provide meaningful benefit for otherwise refractory malignancies. As clinical indications for CAR-T cells are expanding, hospitals hitherto not active in the field of immune effector cell therapy will need to build capacity and expertise. The GoCART Coalition seeks to disseminate knowledge and skills to facilitate the introduction of CAR-T cells and to standardize management and documentation of CAR-T cell recipients, in order to optimize outcomes and to be able to benchmark clinical results against other centers. Apheresis generates the starting material for CAR-T cell manufacturing. This guide provides some initial suggestions for patient's apheresis readiness and performance to collect starting material and should thus facilitate the implementation of a CAR-T-starting material apheresis facility. It cannot replace, of course, the extensive training needed to perform qualitative apheresis collections in compliance with national and international regulations and assess their cellular composition and biological safety.

Abstract
Autologous hematopoietic stem cell transplantation (aHSCT) is a well-established treatment for malignancies such as multiple myeloma (MM) and lymphomas. Various changes in the field over the past decade, including the frequent use of tandem aHSCT in MM, the advent of novel therapies for the treatment of MM and lymphoma, and the addition of new stem cell mobilization techniques, have led to the need to reassess current stem cell mobilization strategies. Mobilization failures with traditional strategies are common and result in delays in treatment and increased cost and resource utilization. Recently, plerixafor-containing strategies have been shown to significantly reduce mobilization failure rates, but the ideal method to maximize stem cell yields and minimize costs associated with collection has not yet been determined. A panel of experts convened to discuss the currently available data on autologous hematopoietic stem cell mobilization and transplantation and to devise guidelines to optimize mobilization strategies. Herein is a summary of their discussion and consensus.

Abstract
Autologous hematopoietic stem cell (HSC) transplantation today is the standard treatment for a wide variety of haematological and oncological diseases. HSC are collected from peripheral blood by leukapheresis (HPC-A) following chemotherapy and/or growth factor-mediated mobilization. The ideal HPC-A collection allows to reach the CD34(+) target dose through a single, tailored leukapheresis. The aim of this paper was to find out which collection parameter might play a key role in obtaining a CD34 dose >4×10(6)/kg with a reduced number of leukapheresis. To address this issue, a multivariate logistic regression was carried out on several operational and laboratory parameters from 943 HPC-A collections performed in 600 hematological and oncological patients. We observed a CD34(+) cells collection efficiency (CE) >50% when patient's pre-apheresis total WBC count was lower than 12.5×10(6)/mL. At the same time, the likelihood of reaching the CD34(+) cells target dose/kg increased from 6 to 3 times when the pre-apheresis WBC count ×10(6)/mL t was below 4.3 (OR=6.1; 2.6-14.1) and between 4.3 and 7 (OR=2.8; 1.4-5.7) respectively when compared to a pre-apheresis WBC count >36×10(6)/mL.

Abstract
Peripheral blood progenitor cells (PBPC) are commonly used as a stem cell source for autologous transplantation. This study was undertaken to evaluate blood cell separators with respect to separation results and content of the harvest. Forty autologous PBPC collections in patients with hematological malignancies were performed with either the Amicus or the COM.TEC cell separators. The median product volume was lower with the Amicus compared to the COM.TEC (125 mL vs. 300 mL; p < 0.001). There was no statistically significant difference in the median number of CD34+ cell/kg in product between the Amicus and the COM.TEC (3.0 x 10(6) vs. 4.1 x 10(6); p = 0.129). There was a statistically higher mean volume of ACD used in collections on the Amicus compared to the COM.TEC (1040 +/- 241 mL vs. 868 +/- 176 mL; p = 0.019). There was a statistical difference in platelet (PLT) contamination of the products between the Amicus and the COM.TEC (0.3 x 10(11) vs. 1.1 x 10(11); p < 0.001). The median % decrease in PB PLT count was statistically higher in the COM.TEC compared to the Amicus instruments (18.5% vs. 9.5%; p = 0.028). In conclusion, both instruments collected PBPCs efficiently. However, Amicus has the advantage of lower PLT contamination in the product, and less decrease in PB platelet count with lower product volume in autologous setting.

Abstract
The combination of effective mobilisation protocols and efficient use of apheresis machines has caused peripheral blood progenitor cells (PBPC) transplantation to grow rapidly. The development of apheresis technology has improved over the years. Today PBSC procedures have changed towards systems to minimise operator interaction and to reduce the collection of undesired cells such as polymorphonuclear cells and platelets using functionally closed, sterile environments for PBSC collection in keeping with Good Manufacturing Practice guidelines. Blood cell separators with continuous flow technique allow the processing of more blood than intermittent flow devices resulting in higher PBSC yields. Large volume leukapheresis with the processing of 3-4-fold donor's/patient's blood volume can increase the number of collected progenitor cells. Therefore, intermittent flow cell separators are indicated if only single vein access is available. Anticoagulant induced hypocalcaemia is an often observed side effect in long lasting PBPC harvesting and monitoring of electrolytes should be performed especially at the end of the apheresis procedure to supplement low levels of potassium, calcium or magnesium. Refinement and improvement of collection techniques continue to add to the armamentarium of current approaches for cancer and non-malignant conditions and will enable future strategies.
