Nonmyeloablative Allogeneic Stem Cell Transplantation From HLA-Matched Unrelated Donor for the Treatment of Hematologic Disorders

Plain-language summary
Allogeneic stem cell transplantation may provide long-term remissions for some patients with hematological malignancies. However, allogeneic transplantation is associated with a significant risk of potentially life threatening complications due to the effects of chemotherapy and radiation on the body and the risks of serious infection. In addition, patients may develop a condition called Graft versus host disease that arises from an inflammatory reaction of the donor cells against the recipient's normal tissues. The risk of graft versus host disease is somewhat increased in patients who are receiving a transplant from an unrelated donor.
One approach to reduce the toxicity of allogeneic transplantation is a strategy call nonmyeloablative or "mini" transplants. In this approach, patients receive a lower dose of chemotherapy in an effort to limit treatment related side effects. Patients undergoing this kind of transplant remain at risk for graft versus host disease particularly if they receive a transplant from an unrelated donor. The purpose of this research study is to examine the ability of a drug called CAMPATH-1H to reduce the risk of graft versus host disease and make transplantation safer. CAMPATH-1H binds to and eliminates cells in the system such as T cells that can cause graft versus host disease (GvHD). As a result, earlier studies have shown that patients who receive CAMPATH-1H with an allogeneic transplant have a lower risk of GvHD. In the present study, we will examine the impact of treatment with CAMPATH-1H as part of an allogeneic transplant on the development of GvHD and infection. In addition, we will study the effects of CAMPATH-1H on the immune system by testing blood samples in the laboratory.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age less than 65 years. There is no lower age limit. Patients 65 years and older will be accrued on a case-by-case basis to this protocol, after discussion and approval by the principal investigator. The acceptance to this protocol for such patients would be based on the absence of coexisting medical problems, which would seriously compromise the patient's ability to tolerate the known morbidity and risks of bone marrow transplantation.
* Patients must have a 5/6 or 6/6 HLA matched, unrelated donor of bone marrow stem cells.
* Each patient must be willing to participate as a research subject and must sign an informed consent form after having been advised as to the nature and risk of the study prior to entering the protocol. Parents or legal guardians of patients who are minors will sign the informed consent form after being advised of the nature and risks of the study. Attending physicians in the Bone Marrow Transplant Service will enroll patients to this study and will obtain written consents.
Eligibility Criteria - Donor
* 5/6 or 6/6 HLA matched with the recipient as determined by molecular testing. Donors will be identified through the National Marrow Donor Program for unrelated donors.
* Donor selection will be performed as outlined in the donor selection SOP's. In patients who have more than one potential donor preference will be given to donors who have no evidence of CMV exposure (if the recipient is CMV-), those who are younger and those who …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Primary objective of study is to determine the safety of non-myeloablative allogenic stem cell transplantation from matched unrelated donors in patients with hematologic malignancies with a focus on the incidence of treatment-related mortality.
