Belimumab for Prevention of Chronic Graft-versus-Host Disease Following Allogeneic Hematopoietic Cell Transplantation
Study Details
Study Description
Brief Summary
Given the role of B cells in the pathophysiology of chronic graft versus host disease (GvHD), the association between elevated BAFF levels post-transplant in abnormal B-cell homeostasis and chronic GvHD, and the efficacy of belimumab in the inhibition of soluble human B lymphocyte stimulator protein (BAFF) signaling, these proof-of-principle findings support the rational for use of belimumab as prophylaxis of chronic GvHD. The investigators propose a pilot and feasibility study to assess the safety and tolerability, as well as preliminary efficacy, of belimumab as prophylaxis of chronic GvHD following allogeneic hematopoietic cell transplantation (alloHCT). The investigators' central hypothesis is that belimumab will be well tolerated and have a favorable effect on incidence and severity of chronic GvHD.

Outcome Measures
Primary Outcome Measures
- Safety and tolerability of belimumab as prophylaxis of chronic GvHD in subjects following alloHCT as measured by number of participants who experience each adverse event [30 days following the completion of treatment (approximately 7 months)]
-Adverse events will be graded according to CTCAE v4.03.
Secondary Outcome Measures
- Incidence and severity of chronic GvHD [6 months after alloHCT]
-The presence of chronic GvHD will be determined according to the 2014 NIH Criteria. If chronic GvHD is diagnosed, each organ will be scored 0-3 and graded, according to the 2014 NIH criteria for Diagnosing and Staging of Chronic GvHD. These data will allow calculation of the NIH global severity score of mild, moderate or severe.
- Incidence and severity of chronic GvHD [12 months after alloHCT]
-The presence of chronic GvHD will be determined according to the 2014 NIH Criteria. If chronic GvHD is diagnosed, each organ will be scored 0-3 and graded, according to the 2014 NIH criteria for Diagnosing and Staging of Chronic GvHD. These data will allow calculation of the NIH global severity score of mild, moderate or severe.
- Incidence and severity of chronic GvHD [24 months after alloHCT]
-The presence of chronic GvHD will be determined according to the 2014 NIH Criteria. If chronic GvHD is diagnosed, each organ will be scored 0-3 and graded, according to the 2014 NIH criteria for Diagnosing and Staging of Chronic GvHD. These data will allow calculation of the NIH global severity score of mild, moderate or severe.
- Incidence and severity of acute GvHD [3 months after alloHCT]
-Acute GvHD will be graded according to modified Glucksberg scale (I-IV)
- Incidence and severity of acute GvHD [6 months after alloHCT]
-Acute GvHD will be graded according to modified Glucksberg scale (I-IV)
- Overall survival [6 months after alloHCT]
-Overall survival will be determined from date of belimumab initiation, with death from any cause as the event of interest, and censoring at last follow up date for those with incomplete observations.
- Overall survival [12 months after alloHCT]
-Overall survival will be determined from date of belimumab initiation, with death from any cause as the event of interest, and censoring at last follow up date for those with incomplete observations.
- Overall survival [24 months after alloHCT]
-Overall survival will be determined from date of belimumab initiation, with death from any cause as the event of interest, and censoring at last follow up date for those with incomplete observations.
- Relapse rate [6 months after alloHCT]
-Relapse rate will be determined from date of belimumab initiation and censoring at last follow up date for those with incomplete observations.
- Relapse rate [12 months after alloHCT]
-Relapse rate will be determined from date of belimumab initiation and censoring at last follow up date for those with incomplete observations.
- Relapse rate [24 months after alloHCT]
-Relapse rate will be determined from date of belimumab initiation and censoring at last follow up date for those with incomplete observations.
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by duration [6 months after alloHCT]
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by dose [6 months after alloHCT]
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by duration [12 months after alloHCT]
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by dose [12 months after alloHCT]
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by dose [24 months after alloHCT]
- Overall corticosteroid requirement for treatment of chronic GvHD as measured by duration [24 months after alloHCT]
- Necessity to use alternative treatment modalities for chronic GvHD [6 months after alloHCT]
-The use of additional systemic immune suppressive agents will be captured at each study visit.
