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 Outcomes (1)

  • 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

    * Adverse events were graded according to CTCAE v4.03. * All adverse events were collected with the exception of: * Adverse events that are less than CTCAE grade 3 unless the AE met the definition of a serious adverse event. * Adverse events not of special interest as defined in the protocol (special interest AEs will be recorded regardless of grade, including those thought to be related to chronic GvHD)

    From start of treatment through 30 days following the completion of treatment (median length of follow-up 205 days, full range 56-229 days)

Secondary Outcomes (10)

  • Incidence and Severity of Chronic GvHD

    Cycle 3 (each cycle is 4 weeks), Cycle 4, Cycle 5, Cycle 6, Cycle 7, 6 months, 9 months, 12 months, 15 months, 18 months, 21 months, and 24 months

  • Incidence and Severity of Acute GvHD

    Cycle 3 (each cycle is 4 weeks), Cycle 4, Cycle 5, Cycle 6, Cycle 7, and 6 months

  • Overall Survival

    6 months, 12 months, and 24 months after alloHCT

  • Relapse Rate

    6 months, 8 months, 12 months, and 24 months post-alloHCT

  • Overall Corticosteroid Requirement for Treatment of Chronic GvHD

    6 months after alloHCT

  • +5 more secondary outcomes

Study Arms (1)

Belimumab

EXPERIMENTAL

* Subjects meeting eligibility criteria will start treatment between Day +30 and Day +80 after alloHCT * Belimumab will be administered intravenously every 2 weeks for 3 doses followed by 4 doses at monthly intervals, for a total of 7 doses (6 months)

Drug: Belimumab
