Palifermin for Stem Cell Transplant Outcomes
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores whether the drug palifermin can enhance the outcome of stem cell transplants from HLA-matched unrelated donors. The main goals are to determine if palifermin is safe, reduces the risk of graft-versus-host disease (where donor cells attack the body), and improves immune function after the transplant. Individuals with blood or bone marrow cancer who lack an HLA-matched sibling donor but have a matched unrelated donor may be suitable candidates. Participants will receive chemotherapy and palifermin, undergo a stem cell transplant, and then be closely monitored. As a Phase 1/Phase 2 trial, this research aims to understand how the treatment works in people and measure its effectiveness in an initial group, offering participants a chance to contribute to groundbreaking medical advancements.
Will I have to stop taking my current medications?
The trial protocol does not specify whether you need to stop taking your current medications. However, since participants will undergo chemotherapy and receive other drugs, it's possible that some medications may need to be adjusted. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that palifermin is generally safe for patients undergoing hematopoietic stem cell transplantation (HSCT). Studies have found that palifermin reduces the need for nutritional supplements and pain relief after certain types of HSCT, indicating good tolerance. Another study tracked patients for up to 15 years and confirmed palifermin's long-term safety. Additionally, palifermin has been proven to reduce severe oral mucositis, or painful mouth sores, in patients with blood cancers undergoing HSCT. These findings suggest that palifermin can be a safe option for patients, although individual experiences may vary.12345
Why do researchers think this study treatment might be promising?
Researchers are excited about palifermin for stem cell transplant outcomes because it has a unique role in reducing the side effects of chemotherapy. Unlike standard treatments that focus solely on eliminating cancer cells, palifermin is engineered to protect and repair the cells lining the mouth and throat, which are often damaged during the aggressive cancer treatments. This protective mechanism could lead to fewer complications and a quicker recovery for patients undergoing stem cell transplants, making the overall treatment process more tolerable. Additionally, palifermin is being tested at different doses to optimize its effectiveness, which could further enhance patient outcomes.
What evidence suggests that palifermin might be an effective treatment for improving stem cell transplant outcomes?
Research has shown that palifermin, which participants in this trial will receive, can reduce painful mouth sores, known as oral mucositis, in individuals undergoing stem cell transplants from donors. Studies have found that it lessens the severity and frequency of these sores. While its primary benefit is reducing mouth sores, its effectiveness in preventing long-term complications like chronic graft-versus-host disease (GVHD) or boosting the immune system post-transplant remains uncertain. Some research indicates it may not significantly affect transplant outcomes in younger patients, but it is generally considered safe. Palifermin is a lab-made protein that protects and heals the mouth and gut lining during treatment.15678

Are You a Good Fit for This Trial?
Adults over 18 with blood or bone marrow cancer, no HLA-matched sibling donor but a potential unrelated match, must understand and consent to the study. They should have good physical function, agree to use contraception if applicable, and live in the US. Excluded are HIV patients, pregnant women, those with certain psychiatric conditions or active infections not responding to treatment.Inclusion Criteria
