Belimumab for Treatment of cGVHD Following Allo-HCT

January 16, 2023 updated by: xuna

Belimumab for Treatment of Chronic Graft-versus-Host Disease Following Allogeneic Hematopoietic Cell Transplantation

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 treatment of chronic GvHD.The investigators propose a pilot and feasibility study to assess the safety and tolerability, as well as preliminary efficacy, of belimumab a treatment of cGvHD following allogeneic hematopoietic cell transplantation (alloHCT). The investigators' central hypothesis is that belimumab will be well tolerated and have a favorable effect on chronic GvHD,and we explored therapeutic dosage of belimumab.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
