Rapamycin (RAPA, RapamuneR) (sirolimus) is an immunosuppressive agent that was approved by the FDA in 1999. It is a macrocyclic lactone that is structurally similar to Tacrolimus (FK506) and binds to the same intracellular protein as FK506, FKBP1,2,3, but it has an entirely different mechanism of action and a different principal target protein. The target of the RAPA: FKBP complex is the mammalian target of rapamycin (mTOR). Unlike the calcineurin inhibitors cyclosporine (CSA) and - FK506, RAPA exerts its effects by inhibiting growth factor-driven transduction signals in the T-cell response to alloantigen, thus preventing proliferation among T and B lymphocytes3,4.
Other Name: (RAPA, RapamuneR) (sirolimus)
- Number of Participants With Transplant-related Mortality [ Time Frame: 24 months after transplant ]Death not associated with relapse. We determined that if transplant related mortality(TRM) 25% at day 100 or if Grade III-IV (severe, life threatening, or disabling) acute GVHD was >30% a stopping rule would be triggered.
- Two Year Overall Survival [ Time Frame: 24 months after transplant ]The probability that a given patient will be alive two years after transplantation. The Kaplan-Meier product limit method was used to compute the probability of overall survival to 2 years. Greenwood's formula was used to compute the standard error.
- Percentage of Patients Developing Acute Graft vs. Host Disease (GVHD) [ Time Frame: 180 days ]Cumulative incidence of Grade 2-4 acute GVHD at 180 days.
