A prospective, multicenter study that will establish a repository of biospecimens and clinical data from patients undergoing hematopoietic stem cell transplant (HCT) or gene therapy (GT) for treatment of non-malignant blood diseases.
This is a prospective, multicenter, study that will establish a repository of biospecimens and clinical data from patients undergoing hematopoietic stem cell transplant (HCT) or gene therapy (GT) for treatment of non-malignant blood diseases. The enrollment goal is 375 participants and up to all consenting 100 related donors (approximately 100 are anticipated), accrued over 4 years. Participants will be followed until the end of study, but continued collection of specimens and clinical data may continue to allow up to 15 years of follow-up for all enrolled participants if funds are available. Participants with a diagnosis of Aplastic Anemia or Hemoglobinopathies or bone marrow failure undergoing HCT or GT for management of their underlying disease. There is no treatment intervention in this study. Treatment will be at the provider's discretion. Participants will provide blood and other biospecimens pre and post-intervention at specified intervals. 375 participants and approximately 100 related donors will be enrolled from 35 sites.
371 studies on the registry are indexed under Anemia, Aplastic; 98 are open to participants now.
This study's planned enrollment of 375 is above the median of 100 across 64 observational studies indexed under Anemia, Aplastic.
Browse Anemia, Aplastic studies →Medical College of Wisconsin is the lead sponsor of 548 studies on the registry; 122 are open to participants now.
Of its 75 completed or terminated interventional studies of FDA-regulated products, 57 (76%) have results posted.

Patients undergoing HCT or GT for treatment of Non-malignant blood disorders: Aplastic Anemia, Hemoglobinopathies or Bone Marrow Failure. Related donors of enrolled participants undergoing HCT are also eligible for the study.
HCT/GT Inclusion:
Patients with a diagnosis of Aplastic Anemia (AA), hemoglobinopathies or bone marrow failure from other causes except for malignant diseases will be eligible for enrollment on this protocol:
HCT/GT Exclusion
Related Donor Inclusion:
1. All related donors for eligible recipients undergoing allogeneic HCT for AA, hemoglobinopathies, or bone marrow failure as defined in the recipient eligibility criteria above are eligible. Note: HCT recipient participants will remain eligible if the related donor declines to participate in the study.
Related Donor Exclusion:
1. Donor weight ≤ 10.0 kg at time of study enrollment
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Develop a biorepository that will establish mechanistic insights and biologic correlates to key casues of fialure of HCT and GT for Non-malignant Diseases (NMD).
Retention of biospecimen samples with DNA
Time frame: 5 Years
Identify new therapeutic targets for NMD and HCT or GT related complications leading to development of more targeted and effective therapies.
