Background Acute graft-versus-host disease (aGVHD) is common after double-unit cord blood transplantation (CBT) with an incidence of grade II-IV aGVHD as high as 55% by day 180 in patients transplanted without ATG. aGVHD is associated with increased morbidity and transplant-related mortality (TRM). Mycophenolate mofetil (MMF) combined with a calcineurin-inhibitor is commonly used to prevent GVHD after CBT. However, unlike the 1 gram (gm) every 8 hours dosing that is now standard in adult donor allografts, MMF dosing in CBT has traditionally been every 12 hours. Our center has increased MMF dose from 1 gm every 12 (q12) to 1 gm every 8 (q8) hours in an effort to reduce severe aGVHD after double-unit CBT. However, the efficacy of this intervention is not established and a theoretical concern is that intensified MMF dosing could result in an increased risk of delayed engraftment or graft failure. Methods We evaluated 171 double-unit CBT recipients (median age 39 years, range 0.9-71) transplanted with either myeloablative (MA, n = 133) or non-myeloablative (NMA, n = 38) conditioning for high-risk hematologic malignancies between 10/2005 and 4/2013. CB units were 4-6/6 HLA-A, -B antigen, -DRB1 allele matched to the recipient (16 6/6, 171 5/6, 155 4/6). All patients received GVHD prophylaxis with intravenous calcineurin-inhibitor (predominantly CSA) and MMF from day -3 without ATG. Prior to 9/2009, 80 patients (47%) received MMF 1 gm IV q12 (and those <12 years received 15 mg/kg/dose). From 9/2009, 91 patients (53%) received MMF at 1 gm IV q8 for patients both >12 years and ≥50 kg (or 15 mg/kg/dose if >12 years but <50 kg, or 20 mg/kg/dose if <12 years). The Gray's test compared the incidence of GVHD across the q12 and q8 dosing while the log-rank test was used to compare progression-free survival (PFS). Results Patient characteristics and infused viable CD34+ cell doses were similar in the q12 and q8 MMF groups. A comparison of transplant outcomes by MMF dosing is shown (Table). There were no differences in the time to neutrophil or platelet engraftment and the median time to count recovery was also similar. The incidences of grade II-IV aGVHD at day 100 were similar in the groups (46% vs 52%). However, there was a suggestion of decreased grade III-IV aGVHD at day 100 in the q8 MMF group (12%) versus the q12 group (21%), although this comparison did not reach significance. With a median follow-up of 41 months (range 3-94), the PFS in each dosing group was not significantly different. Conclusions We demonstrated that intensified q8 MMF dosing is safe from the standpoint of engraftment and toxicity. There was a suggestion of decreased severe grade III-IV aGVHD in recipients of 1 gm IV every 8 hours. While a larger analysis is needed to further investigate these findings, the results are encouraging. They suggest that, as with adult donor allografts, intensified q8 hour MMF dosing should be the dose investigated for the prevention of aGVHD in CBT recipients transplanted with CSA/ MMF prophylaxis without ATG. Finally, aGVHD prophylaxis could be further optimized in CSA/ MMF-based CBT by mycophenolic acid trough level drug monitoring, early post-transplant biomarker measurements such as ST2, and delayed taper post-transplant.

Abstract BACKGROUND Limited information is available on incidences and clinical features of acute graft-versus host disease (GVHD) after cord blood transplantation and large-sized researches have been awaited. METHODS We investigated the incidences and clinical features of acute GVHD in 2,015 patients reported to the Japan Cord Blood Bank Network, who underwent cord blood transplantation between June 1997 and August 2006. RESULTS Of 2,015 patients, 1481 patients (73%) achieved neutrophil engraftment at a median of day 22 (range, 6–81). Cumulative incidence of neutrophil recovery at day 100 was 0.74 (95%CI, 0.73–0.76). Of 2015 patients, 708 patients developed grade II-IV acute GVHD: grade II (n=423), grade III (n=237), and grade IV (n=48). The median onset was day 19 (range, 4–190). The cumulative incidences of grade II-IV and III-IV acute GVHD at day 100 were 0.35 (95% CI, 0.33–0.37) and 0.14 (95% CI, 0.12–0.15), respectively. Skin and gastrointestinal acute GVHD was documented in 1,006 and 405 patients, respectively, whereas liver GVHD was diagnosed in 149 patients. Multivariate analysis identified the following predictors of grade II-IV acute GVHD: the number of infused nucleated cells, transplantation from female donors to female recipients, TBI-containing preparative regimens, methotrexate-containing GVHD prophylaxis, and tacrolimus-based GVHD prophylaxis. Overall survival rates at three years of patients with grade 0-I, II and III-IV GVHD who survived 100 days or longer were 0.58 (95%CI, 0.53–0.63), 0.61 (95% CI, 0.54–0.67) and 0.40 (95%CI, 0.31–0.49), respectively. CONCLUSIONS Acute GVHD following cord blood transplantation is mild and has graft-versus malignancy effects. Probability of event free survival after cord blood tranplantation in the patients with grade 0-I, II and III-IV who survived 100 days or longer Event - free survival of the patients with grade 0-I, II and III-IV GVHD who survived 100 days or longer was 0.54 (95% CI, 0.49–0.59), 0.58 (95%CI, 0.52–0.65) and 0.41 (95%CI, 0.32–0.49),respectively,3 years after transplantation. Probability of event free survival after cord blood tranplantation in the patients with grade 0-I, II and III-IV who survived 100 days or longer Event - free survival of the patients with grade 0-I, II and III-IV GVHD who survived 100 days or longer was 0.54 (95% CI, 0.49–0.59), 0.58 (95%CI, 0.52–0.65) and 0.41 (95%CI, 0.32–0.49),respectively,3 years after transplantation.
