A subset of autoimmune diseases (ADs) in children and young adults are life-threatening and unresponsive to conventional treatments. In these patients, the delivery of high dose immunosuppressive therapy followed by autologous stem cell transplant (ASCT) offers a treatment strategy capable of purging the pathogenic, autoreactive immune system and an opportunity for "immune reset." This strategy has been used in adults across a myriad of indications with evidence for efficacy. This study proposes a pilot study to evaluate this therapeutic strategy in children and young adults with systemic sclerosis (SSc) and systemic lupus erythematosis (SLE), two potentially life threatening autoimmune diseases that may response to this therapeutic approach.

|---|---|---|---|
| CD3/CD19 depleted ASCT | Experimental | The test article is autologous stem cell transplant with a CD3/CD19-depleted stem cell product. |

|---|---|---|---|---|
| Depletion of CD3/CD19 in an autologous stem cell transplant | Biological | The purpose of this study is to determine the safety and feasibility of CD3/CD19 depleted autologous stem cell transplant for the treatment of life threatening autoimmune disease. We will perform CD3/CD19 depletion using the CliniMACs device as a means of purging autoreactive T and B cells from the transfused autologous stem cell product, while retaining some immune function, namely natural killer cells and monocytes in the product. |
| Measure | Description | Time Frame |
