What is the purpose of this trial?

This trial tests the safety and effectiveness of using unlicensed cord blood units (blood from a newborn's umbilical cord) for stem cell transplants. These transplants can treat blood disorders like blood cancers. The trial targets individuals scheduled for a stem cell transplant as part of their treatment. Researchers will monitor participants for any issues during and after the transplant for up to a year. The study aims to determine if these unlicensed units can be a safe option for patients in need. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

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 prior data suggests that cord blood units are safe for stem cell transplants?

Research shows that about 10,000 children and adults worldwide have received cord blood transplants to treat blood cancers and other diseases. Studies have found that cord blood is rich in stem cells, which help the body produce new blood cells and strengthen the immune system.

Cord blood transplants are generally considered safe, but like any medical treatment, they can have side effects. Common issues might include infections or reactions to the transplant, usually manageable with proper care and monitoring.

Although the cord blood units in this trial are not licensed, past use of cord blood in transplants has shown positive results, suggesting that the treatment is well-tolerated. Participants in the trial will be closely monitored for any problems during and after the transplant to ensure safety. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment?

Researchers are excited about cord blood transplants for blood disorders because they offer a unique source of stem cells that can regenerate healthy blood cells. Unlike traditional bone marrow transplants, which require a close match between donor and recipient, cord blood transplants are less reliant on perfect matches, making it easier to find a suitable donor. Additionally, cord blood is rich in stem cells that have a potent ability to grow and form new blood cells, potentially leading to faster recovery times and lower risks of complications. This makes cord blood transplants a promising alternative, especially for patients who struggle to find a compatible bone marrow donor.

What evidence suggests that cord blood units are effective for blood disorders?

Research has shown that cord blood stem cells can treat around 80 diseases, particularly those affecting the blood, such as sickle cell disease. Studies have found that cord blood is rich in stem cells, which are crucial for rebuilding the blood and immune systems. Cord blood transplants perform comparably to bone marrow transplants, a common treatment for blood disorders. The cells from cord blood possess natural advantages, making them effective in treating these conditions. Overall, this evidence supports the potential success of using cord blood for stem cell transplants in individuals with blood disorders. ^{2 3 4 6 7}

Published Research Related to This Trial

A total of 8623 umbilical cord blood (UCB) units were collected in a provincial bank in Guangzhou, China, with 4147 units (48.1%) stored for potential transplantation, demonstrating effective donor screening and processing protocols.

The study reported high cell viability (97.8%) and successful engraftment times for transplanted patients, with children showing faster neutrophil engraftment (17 days) compared to adults (20 days), indicating the efficacy of UCB as a source of hematopoietic stem cells for transplantation.

A study analyzing 140 reported adverse events from cord blood infusions in Japan found that hypertension was the most common side effect, while serious adverse events like anaphylaxis occurred at a low frequency of 0.23%.

The research highlighted the need for standardized reporting systems for adverse events in cord blood transplantation, as existing classification criteria were unable to classify a significant number of cases, which could hinder efforts to improve safety and reduce risks.

In a study of 609 patients with upper urinary tract urothelial carcinoma (UUT-UC), both open nephroureterectomy (ONU) and laparoscopic nephroureterectomy (LNU) showed similar 5-year cancer-specific survival (CSS) and recurrence-free survival (RFS) rates, indicating that LNU is a viable alternative to traditional surgery.

Postoperative complications were comparable between the two surgical approaches, suggesting that LNU does not compromise safety compared to ONU, as evidenced by a median follow-up of 27 months and no significant differences in complications.

In a meta-analysis of 3434 participants across seven studies, haplo-identical transplants using post-transplant cyclophosphamide (PTCy-haplo) showed a significantly lower risk of acute graft-versus-host disease (aGVHD) and relapse compared to umbilical cord transplants (UC).

The PTCy-haplo group also demonstrated improved overall survival rates, although it was associated with a higher risk of chronic graft-versus-host disease (cGVHD) compared to UC transplants.

The FDA's guidance on donor screening to prevent Zika virus transmission has led to a significant reduction in the number of available umbilical cord blood units for transplantation, which are critical for hematopoietic stem cell therapies.

There is an urgent need for updated assessments of travel risks related to Zika, improved screening tests for Zika in cord blood, and more research on the virus's transmissibility to ensure the safety and availability of these vital medical resources.

Umbilical cord blood transplants are a valuable alternative for treating blood cancers, offering rapid availability and less strict matching requirements, which can reduce the risk of relapse and graft-versus-host disease.

Double-unit umbilical cord blood transplants may improve neutrophil recovery rates and address the issue of limited cell doses, especially in adult patients, while also serving as a platform for testing new expansion and homing techniques.

Should double cord blood transplants be the preferred choice when a sibling donor is unavailable? Wagner, JE.[2021]

In a study involving 13 patients with leukemia, double-unit umbilical cord blood transplantation (UCBT) showed a high engraftment rate, with 92.3% of patients achieving neutrophil and platelet engraftment within a median of 21 and 34 days, respectively.

The procedure demonstrated a manageable safety profile, with only one case of grade II acute graft-versus-host disease and limited chronic GVHD in survivors, suggesting that double-unit UCBT can be a feasible option for adults and adolescents with leukemia despite HLA mismatches.

In a study involving 224 patients aged 1 to 21 with hematologic cancer, the overall survival rates after single-unit and double-unit cord-blood transplantation were similar, with 1-year survival rates of 73% for single-unit and 65% for double-unit transplants.

However, recipients of single-unit cord-blood transplants experienced better platelet recovery and had a lower incidence of severe graft-versus-host disease (GVHD), suggesting that single-unit transplants may offer certain advantages despite similar survival outcomes.
