The objective of this study is to develop a feasible and safe regimen for minimization of immune suppression in recipients of vascularized composite allotransplants (VCA) using a daily dose of recombinant IL-2. In order to achieve this aim, this trial will:
- Perform VCA in 5 eligible subjects;
- Administer recombinant IL-2 at a low-dose to promote the expansion and function of regulatory T cells in subjects who received VCA; and
- Minimize immune suppression to tacrolimus single therapy in subjects who received VCA and recombinant IL-2.
This trial will also investigate if it is possible to predict immune rejection in VCA using blood and tissue samples from recipients of VCA.
Lastly, this trial will develop non-invasive technologies to monitor for VCA rejection. These technologies will involve magnetic resonance imaging. Multi-contrast ultra-high resolution MR imaging (MRI) with serial direct planimetry will be performed in recipients of VCA.

Subjects who receive transplantation and undergo IL-2 treatment
Subjects will receive vascularized composite allotransplantation (e.g. facial, hand and/or abdominal wall transplants) under conventional immune suppression. No sooner than 3 months after VCA, subjects will receive a protocol of daily recombinant IL-2 at low doses for 8 weeks.
- Number of regulatory T cells [ Time Frame: 4-24 months ]
- Number of episodes of rejection [ Time Frame: 1-24 months ]
- T-cell alloreactivity measured by ELISPOT [ Time Frame: 4-24 months ]
- Steroid dose [ Time Frame: 6-24 months ]
- Mycophenolate dose [ Time Frame: 8-24 months ]
