Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Evidence of moderate to severe periportal fibrosis, determined by liver biopsy, if applicable. 10. Active, uncontrolled infection that would be a contraindication to safe use of high-dose immunosuppressive therapy or cyclophosphamide. 11. Hematologic abnormalities as defined by any of the following peripheral blood counts: 1. ANC < 1500 cell/µL. 2. Platelets < 100,000 cells/ µL. 3. Hemoglobin < 9.0 g/dL. 12. Evidence of myelodysplasia (MDS), confirmed by bone marrow aspirate, if applicable. 13. Malignancy within 2 years prior to enrollment, excluding adequately treated squamous cell cancer, basal cell carcinoma or carcinoma in situ. Treatment should have been completed with cure/remission status documented for at least 2 years, with the exception of hormonal therapy for breast cancer. 14. Females who are pregnant or who are lactating. 15. Tobacco use, by subject admission, within previous 4 weeks of time of consent. 16.

Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

This is a single center, phase II trial where after a process of stem cell mobilization and conditioning, adult subjects receive a CD34-selected autologous peripheral blood stem cell rescue. By virtue of positive selection for the stem/progenitor cell marker of CD34, the graft will be at least 3-log depleted for T, B and NK lymphocytes and other immune cells such as monocytes that may be pathogenic. This is an open label study and there will be no randomization or blinding as a part of this study. The proposed regimen of high-dose immunoablative therapy will demonstrate safety that is consistent or improved with other published regimens in SSc patients, while maintaining a treatment effect. We also hypothesize that our mechanistic studies will yield biomarkers that may herald disease recurrence or progression following alterations in the recovery of immune cells in the skin and/or bronchial lavage or blood. The primary objectives of this study are to determine the safety and treatment effect of high-dose immunoablative therapy followed by transplantation of CD34+ positively selected peripheral blood stem cells (PBSC) for systemic scleroderma (SSc) patients using a regimen designed to maximize patient safety while also aiming to eradicate autoreactive clones responsible for the disease. Safety will be determined by monitoring for death of any cause, regimen-related toxicities, and severe or life-threatening infections. Treatment effect will be determined by assessing event-free survival in comparison to a SSc observational cohort control group treated with standard of care medication (mycophenolate mofetil) at 12 and 36 months post hematopoietic stem cell transplant (HSCT). Enrolled subjects will be followed for survival, secondary malignancies, and SSC activity at least yearly up to 36 months post-HSCT. The secondary objectives of this study are to:
