Ruxolitinib In GvHD (RIG)

November 27, 2019 updated by: Prof. Dr. Nikolas von Bubnoff

Multicentre Phase 2 Trial to Evaluate the Efficacy of Ruxolitinib in Steroid-refractory Acute Multicenter, Randomized Phase 2 Trial to Determine the Response Rate of Ruxolitinib and Best Available Treatment (BAT) Versus BAT in Steroid-refractory Acute Graft-versus-Host Disease (aGvHD)

The preliminary data demonstrate potent activity of Ruxolitinib in steroid-refractory aGvHD. In this phase 2 trial the efficacy of Ruxolitinib and best available treatment (BAT) versus BAT in steroid-refractory acute GvHD in approximately 12 transplantation centers in Germany will be compared. The response by monitoring the clinical GvHD grade, requirement of alternative GvHD active agents and serum levels of pro-inflammatory cytokines will be determined.

Detailed Description

The pathophysiological hallmark of GvHD after allo-HCT is an allogeneic donor T cell re-sponse against recipient antigens. This process is aggravated by increased processing and presentation of host antigens by donor APCs following conditioning treatment. The al-logeneic T cell response leads to inflammation, tissue damage and fibrosis and is mediated by extensive production of inflammatory cytokines such as IL-1, IL-2R, IL-6 and TNF. The signal transmission of inflammatory cytokines in effector cells requires activation of specialized kinases from the family of the Janus kinases. These kinases, JAK1, 2 and 3 are linked to cytokine receptors, and are activated upon binding of the cytokine to the receptor of the inflammatory effector. The JAK1/2 kinase inhibitor Ruxolitinib (INC424) is approved for myelofibrosis. In advanced myelofibrosis, Ruxolitinib lead to sustained clinical remissions with regard to constitutional symptoms, weight loss and spleen size in the majority of treated patients. Of note, clinical responses correlated with a marked reduction in inflammatory plasma cytokines.

Importantly, cytokines down-regulated by Ruxolitinib in patients with myelofibrosis correspond to inflammatory effectors that mediate tissue damage and inflammation in GvHD. These are mainly the cytokines IL- 1, IL -6, TNF and IFN-gamma. Since Ruxolitinib suppresses the JAK1 / 2 cytokine response, we hypothesized that Ruxolitinib might attenuate the cytokine mediated inflammatory tissue damage in GVHD and thus might favourably affect the severity and course of GvHD after allo-HCT.

In vitro, we demonstrated in an allogeneic system (major mismatch mixed-lymphocyte reactions) that co-incubation with Ruxolitinib strongly suppressed both the proliferation of alloge-neic T cells and the production of inflammatory cytokines. Using a very aggressive major mismatch mouse model of acute GvHD Ruxolitinib treatment signifi-cantly prolonged survival of animals (see Figure 1A). In addition, in these animals showed a reduced weight loss, significantly reduced histopathological GvHD severity, suppression of inflammatory cytokines in the serum and a reduction of donor T cells in GvHD target organs such as the intestines.

Sole suppression of cytokine production or cytokine receptor activity by Ruxolitinib would be very similar to already established drugs for GvHD and no major conceptual advance. However we observed that Ruxolitinib did not only suppress cytokine production but also led to increased frequencies of FoxP3+ regulatory T cells. This cell type was previ-ously shown to lead to long-lasting tolerance as compared to the short-term immunosuppression achieved by conventional medication for GvHD.

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.

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.
