Clinical Trial Summary

This study will determine the best ways to collect, process and store umbilical cord blood from babies with sickle cell disease, sickle cell trait and unaffected babies. Sickle cell disease is an abnormality of the hemoglobin in red blood cells that causes the cells to change shape and clump together, preventing their normal flow in the bloodstream. This impairs blood flow to various organs, and the resulting oxygen deprivation causes organ damage.

Cord blood is rich in stem cells (cells produced in the bone marrow that mature to different types of blood cells), which may prove useful in new sickle cell therapies. However, cord blood from babies with sickle cell trait, sickle cell disease and normal babies may act differently under laboratory conditions, so it is important to learn how best to work with blood from all three groups of babies for future use in possible treatments.

Pregnant women between 18 and 45 years of age who are at risk of having an infant with sickle cell disease and normal volunteers who are pregnant and not at risk for this disease may be eligible for this study. Potential participants will be counseled about donating her infant s blood in order to make an informed choice.

All women who participate in the study will provide a medical history and have blood collected from the umbilical cord and placenta (afterbirth) after the baby s delivery. The blood will be tested for various infectious diseases, processed, frozen and stored for research purposes. In addition, blood from women with babies at risk for sickle cell disease will be tested for the presence of the sickle cell gene, tissue typed, and used for research as follows:

• Sickle cell disease - If cord blood tests show the baby has sickle cell disease, the blood will be frozen for an indefinite period of time for possible use in future treatment of the child. This treatment could include stem cell transplantation or gene therapy, treatments are not currently considered routine for sickle cell disease.

• Sickle cell trait or normal hemoglobin - If cord blood tests show the baby has sickle cell trait or is unaffected, the blood will be processed and stored for up to 3 years, during which time it may possibly be used to treat a currently living or future sibling with sickle cell disease. After 3 years, the participant may agree to either have the blood discarded, given to research or moved to another facility for continued storage at the participant s expense, if there is a storage fee. Alternatively, if there is no anticipated future need for the collected blood, or if it does not meet standards needed for future treatment, it will be used in NIH-approved research studies.

Participants and their family doctor or the baby s pediatrician will be contacted twice a year for information about changes in the baby s health. Participants may also be asked permission to perform new tests developed by researchers.

Description:

Umbilical cord blood is a source of hematopoietic stem cells (HSCs) for transplantation or gene therapy. Our goal is to procure umbilical cord blood from newborns at risk for sickle cell disease, sickle cell trait, and related disorders as well as normal newborns and store clinical grade cord blood units (CBU) for future use in clinical transplantation or gene therapy. Cord blood units will be collected from 500 subjects until 50 CBU from newborns with homozygous sickle cell disease (HbSS) have been cryopreserved.

The NIH Sickle Cell Cord Blood Program has contracted Duke University s Carolina Cord Blood Bank/Stem Cell Transplant Laboratory (CCBB/STCL)*^, a CAP and FACTaccredited and CLIA certified laboratory, to facilitate maternal screening, cord blood kit distribution or onsite collection, processing, and storage of cord blood for maternal subjects identified as being at risk of having an infant with sickle cell disease. Mothers between the ages of 18 and 45 years who meet specified medical history criteria will deliver at her preferred hospital using CCBB/STCL s directed donation kit program. The collected CBU and needed samples will be transported to the CCBB/STCL processing facility for processing and storage. Clinical grade frozen CBUs will be transferred to the NIH for future clinical transplantation (related allogeneic transplant) or gene therapy studies (autologous transplant) under an IRB approved protocol.

*Any future mention of CCBB/STCL is understood to be a contracted service for NIH Sickle Cell Cord Blood Program.

^CCBB/STCL has been contracted for a fee-for-service to collect and store cord blood units. CCBB/STCL will not be engaged in human subject research activities (e.g. recruitment, consenting, maintenance/ processing of data, data analysis, manuscript writing, access to personal identifiable information linked to data, and/or access to a key code, etc.).

1. Maternal subjects must be between 18 and 45 years old.

2. Maternal subjects must be able to provide informed consent.

3. Maternal subjects must work with their obstetrician to insure appropriate cord blood collection, sample collection, and completion of related documents.

4. Maternal subjects enrolled on other studies are not excluded, unless the other study may interfere with the present one.

EXCLUSION CRITERIA:

1. The maternal subject will not be eligible for study if she is known to be positive for one or more of the following diseases transmissible by blood: HIV, hepatitis B, hepatitis C, WNV, HTLV or ZIKV.

2. Maternal subject will not be eligible for the study if she has active syphilis, toxoplasmosis, malaria or
