Brief Summary:
This Phase II open label study will evaluate the safety and efficacy of repeat doses of RGI-2001 in combination with standard of care treatment for the prevention of acute graft-vs-host-disease (aGvHD) in subjects following Allogeneic Hematopoietic Stem Cell Transplantation (alloHSCT). These subjects will be compared to contemporary controls.

Condition or disease Intervention/treatment Phase
Graft Vs Host Disease Graft-versus-host-disease Acute-graft-versus-host Disease Prevention of aGVHD Drug: RGI-2001 Drug: Standard of Care Phase 2

Detailed Description:
This is an open-label, multi-center, single-arm study to evaluate six weekly doses of RGI-2001 in combination with standard of care treatment for the prevention of aGvHD in subjects following alloHSCT. The study will include a Safety Run-in Phase to assess the safety and tolerability of 6 weekly doses of RGI-2001 followed by an Expansion Phase in which the potential efficacy of 6 weekly doses of RGI-2001 in addition to standard of care for GvHD prophylaxis will be assessed. Comparison will be made to a contemporaneous control group.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Grades II-IV aGVHD [ Time Frame: Day 100 post-transplant ]
    Acute GVHD will be graded and assessed within the first 100 days post-transplant


Secondary Outcome Measures :
  1. Grades II-IV aGVHD [ Time Frame: Day 180 post-transplant ]
    Acute GVHD will be graded and assessed within 180 days post-transplant

  2. Non-relapse mortality (NRM) rates [ Time Frame: Day 100, 6 months and 1 year post-transplant ]
    The probability of mortality not preceded by relapse of the underlying malignancy will be estimated

  3. Disease-free survival (DFS) [ Time Frame: 6 months and 1 year post-transplant ]
    The probability of survival without relapse of the underlying malignancy will be estimated

  4. GvHD-free, relapse free survival (GRFS) [ Time Frame: 6 months and 1 year post-transplant ]
    The probability of survival without relapse of the underlying malignancy, without severe (grades 3-4) acute GVHD, and without chronic GVHD requiring systemic immunosuppression will be estimated

  5. Overall survival (OS) [ Time Frame: 6 months and 1 year post-transplant ]
    The probability of survival will be estimated
