Trial Summary
What is the purpose of this trial?This trial uses stem cells from a baby's umbilical cord to treat patients who need new healthy stem cells. Patients first get strong medicine to clear out unhealthy cells, then receive the new stem cells, and take medications to prevent complications. Umbilical cord blood has been used in the treatment of various diseases, including leukemias, lymphomas, and immune system disorders.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What data supports the effectiveness of the treatment Cord Blood Transplant for Blood Diseases?
The study on high-dose busulfan/melphalan for autologous transplantation in children with solid tumors showed that this combination is feasible and well-tolerated, with an acceptable mortality rate and proven antitumor activity, suggesting potential effectiveness in similar transplant settings.
12345Is cord blood transplant generally safe for treating blood diseases?
Research shows that using busulfan, fludarabine, and melphalan in cord blood transplants is generally well-tolerated, with acceptable safety profiles in both children and adults. Some studies report manageable side effects like gastrointestinal issues and rare serious complications, but overall, these regimens have been used safely in various conditions.
23567How does the cord blood transplant treatment differ from other treatments for blood diseases?
This treatment is unique because it combines multiple chemotherapy drugs and total body irradiation to prepare the body for a cord blood transplant, which can be an alternative for patients without a matched donor. The combination of drugs like busulfan, fludarabine, and melphalan, along with total body irradiation, aims to reduce the risk of graft failure and relapse, although it may have higher toxicity compared to other regimens.

Total body irradiation-based versus busulfan-based myeloablative conditioning for single-unit cord blood transplantation in adults. [2022]Comparative studies between total body irradiation (TBI)-based and busulfan-based myeloablative conditioning (MAC) regimens for cord blood transplantation (CBT) have been limited. We retrospectively analyzed the results of single-unit CBT in 333 adult patients who received either TBI-based (n = 258) or busulfan-based (n = 75) MAC regimens at our institute. After adjusting for significant variables in the univariate analysis, there were no significant differences in neutrophil recovery (hazard ratio (HR), 0.88; p = .460), grade III-IV acute graft-versus-host disease (GVHD) (HR: 1.40, p = .410), extensive chronic GVHD (HR: 0.73, p = .380), relapse (HR: 0.61, p = .270), non-relapse mortality (HR: 1.38, p = .420), overall survival (HR: 1.18, p = .637), or event-free survival (HR: 1.08, p = .773), although platelet recovery was lower with marginal significance for the busulfan-based regimen (HR: 0.67, p = .068). In subgroup analysis, TBI-based regimens were superior to busulfan-based regimens in terms of survival for acute lymphoblastic leukemia, but not for myeloid malignancies. Further investigation is warranted even for CBT.
High-dose busulfan/melphalan as conditioning for autologous PBPC transplantation in pediatric patients with solid tumors. [2013]We conducted a prospective pilot study to assess the feasibility and safety of high-dose busulfan/melphalan as conditioning therapy prior to autologous PBPC transplantation in pediatric patients with high-risk solid tumors. From January 1995 to January 1999, 30 patients aged 2-21 years (median 8) were entered into the study. There were 14 females and 16 males. Diagnoses included neuroblastoma in 10 patients; Ewing's sarcoma and peripheral neuroectodermal tumor (PNET) in 15 patients and rhabdomyosarcoma in five patients. Treatment consisted of busulfan 16 mg/kg, orally over 4 days (from days -5 to -2) in 6 hourly divided doses, and melphalan at a dose of 140 mg/m2 given by intravenous infusion over 5 min on day -1. G-CSF mobilized PBPC were used as autologous stem-cell rescue. One patient developed a single generalized convulsion during busulfan therapy. The most relevant non-hematologic toxicity was gastrointestinal, manifesting as grade 2-3 mucositis and diarrhea in 12 patients. Two patients died of procedure-related complications, one from veno-occlusive disease of liver and multiorgan failure and the other from adult respiratory distress syndrome. Probability of treatment-related mortality was 6.6 +/- 4.5%. With a median follow-up of 18 months (range, 1-48), 19 patients are alive and disease-free, the actuarial EFS at 4 years being 55 +/- 12% for the whole group. We conclude that high-dose busulfan/melphalan for autologous transplantation in children with solid tumors is feasible even in small patients. It is well-tolerated, with an acceptable transplant-related mortality and has proven antitumor activity.
Two Different Transplant Preconditioning Regimens Combined with Irradiation and Chemotherapy in the Treatment of Childhood Leukemia: Systematic Review and Meta-Analysis. [2023]To observe the therapeutic effect and the incidence of adverse reactions of total body irradiation plus cyclophosphamide (TBI/CY) and busulfan plus cyclophosphamide (BU/CY) in the treatment of pediatric hematopoietic stem cell transplantation.
Randomized trial of busulfan vs total body irradiation containing conditioning regimens for children with acute lymphoblastic leukemia: a Pediatric Blood and Marrow Transplant Consortium study. [2013]Conditioning regimens for children with ALL have generally included total body irradiation (TBI), which may result in significant sequelae. The primary aim of this study was to evaluate the outcome for children with ALL undergoing allogeneic stem cell transplant (SCT) with either busulfan (Bu) or TBI regimens. Patients
Myeloablative intravenous busulfan/fludarabine conditioning does not facilitate reliable engraftment of dual umbilical cord blood grafts in adult recipients. [2021]The efficacy of once-daily intravenous busulfan with fludarabine as a preparative regimen for partially matched umbilical cord blood transplantation has not been formally studied. We randomized 10 adult patients with myeloid malignancies to receive either concurrent or sequential administration of intravenous busulfan 130 mg/m(2) once daily x 4 days and fludarabine 40 mg/m(2) daily x 4 days, followed by dual umbilical cord blood transplantation. The median combined cryopreserved total nucleated cell dose was 3.6 x 10(7)/kg recipient body weight (range: 2.8-4.5 x 10(7)/kg). Graft-versus-host disease (GVHD) prophylaxis was provided by tacrolimus and mycophenolate mofetil (MMF). Donor-derived neutrophil recovery was observed in only 2 of 10 patients, resulting in premature closure of the study as per graft failure stopping rules. We conclude that the myeloablative conditioning regimen of once-daily intravenous busulfan with fludarabine provides insufficient immunosuppression to allow for engraftment of partially matched, dual umbilical cord blood grafts.
Fludarabine and exposure-targeted busulfan compares favorably with busulfan/cyclophosphamide-based regimens in pediatric hematopoietic cell transplantation: maintaining efficacy with less toxicity. [2014]Busulfan (Bu) is used as a myeloablative agent in conditioning regimens before allogeneic hematopoietic cell transplantation (allo-HCT). In line with strategies explored in adults, patient outcomes may be optimized by replacing cyclophosphamide (Cy) with or without melphalan (Mel) with fludarabine (Flu). We compared outcomes in 2 consecutive cohorts of HCT recipients with a nonmalignant HCT indication, a myeloid malignancy, or a lymphoid malignancy with a contraindication for total body irradiation (TBI). Between 2009 and 2012, 64 children received Flu + Bu at a target dose of 80-95 mg·h/L, and between 2005 and 2008, 50 children received Bu targeted to 74-80 mg·h/L + Cy. In the latter group, Mel was added for patients with myeloid malignancy (n = 12). Possible confounding effects of calendar time were studied in 69 patients receiving a myeloablative dose of TBI between 2005 and 2012. Estimated 2-year survival and event-free survival were 82% and 78%, respectively, in the FluBu arm and 78% and 72%, respectively, in the BuCy (Mel) arm (P = not significant). Compared with the BuCy (Mel) arm, less toxicity was noted in the FluBu arm, with lower rates of acute (noninfectious) lung injury (16% versus 36%; P = .007), veno-occlusive disease (3% versus 28%; P = .003), chronic graft-versus-host disease (9% versus 26%; P = .047), adenovirus infection (3% versus 32%; P = .001), and human herpesvirus 6 infection reactivation (21% versus 44%; P = .005). Furthermore, the median duration of neutropenia was shorter in the FluBu arm (11 days versus 22 days; P
Alternative Donor Hematopoietic Cell Transplantation Conditioned With Myeloablative Busulfan, Fludarabine, and Melphalan is Well Tolerated and Effective Against High-risk Myeloid Malignancies. [2022]Busulfan, fludarabine, and melphalan as hematopoietic cell transplant conditioning, was used in 6 patients aged 1 to 19 years with very high-risk myeloid malignancies. This dose regimen had an acceptable toxicity profile resulting in complete donor engraftment even following transplantation of small 2/6 antigen disparate umbilical cord blood grafts. It provided excellent disease control as all patients had high-risk features in terms of cytogenetics, therapy-related leukemia, and/or significant measurable disease before transplant. All patients remain in remission, without acute or chronic graft-versus-host disease with a median follow-up of 24 months. A larger study is indicated to confirm the efficacy and safety of this regimen.
Fludarabine, melphalan, thiotepa and anti-thymocyte globulin conditioning for unrelated cord blood transplant. [2021]Unrelated cord blood transplant (CBT) is an alternative treatment option for patients who lack a matched donor. However, the optimal type and intensity of the preparative regimen remains unclear. We evaluated the toxicity and outcomes of a conditioning regimen consisting of melphalan 140 mg/m(2) (day - 8), thiotepa 10 mg/kg (day - 7), fludarabine 160 mg/m(2) over 4 days (days - 6 to - 3) and rabbit antithymocyte globulin (ATG) 1.25 mg/kg (day - 4) and 1.75 mg/kg (day - 3) (FMT). Forty-seven patients with advanced hematologic malignancies with a median age of 23 years (30 adults and 17 children) were treated. Sixty percent of patients were in remission at transplant. Ninety-one percent of the patients engrafted neutrophils after a median of 22 days, and all but one of the patients achieving donor engraftment had hematopoietic recovery with 100% cord blood-derived cells. Grade 3 gastrointestinal toxicity was the major non-hematopoietic toxicity, occurring in 32% of patients. Cumulative incidence of day-100 grade II-IV acute graft-versus-host disease (aGVHD) and chronic graft-versus-host disease (cGVHD) was 53% and 34%, respectively, and non-relapse mortality at day 100 and 2 years was 11% and 40%. Two-year disease-free and overall survival rates were 31% and 44%, respectively. These results suggest that FMT is a feasible conditioning regimen for patients undergoing CBT.
The development of a myeloablative, reduced-toxicity, conditioning regimen for cord blood transplantation. [2021]Cord blood transplantation is being used with increasing frequency for patients with high-risk hematologic malignancies. Myeloablative preparative regimens provide antitumor efficacy and facilitate engraftment but are associated with higher morbidity and nonrelapse mortality rates than nonablative regimens. We evaluated 3 sequential myeloablative regimens in the cord blood transplant setting. Regimen 1 (melphalan, fludarabine, and thiotepa) produced prompt engraftment and minimal engraftment failure but was associated with a high nonrelapse mortality rate. Regimen 2 (busulfan and fludarabine) was very well tolerated but was associated with a high rate of engraftment failure and relapse. Regimen 3 (busulfan, clofarabine, fludarabine, and low-dose total body irradiation given 9 days after the chemotherapy) was associated with a low rate of engraftment failure but was logistically difficult to administer. Finally, regimen 3 that included the total body irradiation given immediately after the chemotherapy was well tolerated, with prompt engraftment and tumor control. This latter regimen appears to be effective in preliminary studies and warrants further evaluation.
Randomised controlled trial of conditioning regimen for cord blood transplantation for adult myeloid malignancies comparing high-dose cytarabine/cyclophosphamide/total body irradiation with versus without G-CSF priming: G-CONCORD study protocol. [2021]A better long-term quality of life after umbilical cord blood transplantation (CBT) is observed compared with transplants from other alternative donors, whereas graft failure and relapses after CBT are still major issues. To minimise graft failure and relapse after CBT, intensification of conditioning by the addition of high-dose cytosine arabinoside (CA) and concomitant continuous use of granulocyte-colony stimulating factor (G-CSF) are reported to convey a significantly better survival after CBT in some retrospective studies. To confirm the effect of G-CSF plus CA combination, in addition to the standard conditioning regimen, cyclophosphamide (CY)/total body irradiation (TBI), we design a randomised controlled study comparing CA/CY/TBI with versus without G-CSF priming (G-CSF combined conditioned cord blood transplantation [G-CONCORD] study).
