E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary Objectives
1. To describe the effect of combination therapy with IFN-alpha (Pegasys, PegIntron) and JAK1-2-inhibitor treatment (ruxolitinib) evaluated by hematological parameters (Hb, hematocrit, white blood cell count, platelet count, LDH, reduction in JAK2V617-mutation allele burden) and quality of life score, which indirectly will also reflect the remission of the IFN-alpha-induced side effects
|
|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives
1. To investigate whether additional treatment with JAK1-2-inhibitor (ruxolitinib) to patients who show intolerance (due to adverse events) during treatment with interferon-alpha (IFN-alpha) (Pegasys, PegIntron) can improve the efficacy based on individual contribution of the two agents regarding that the JAK1-2 inhibitor through its very potent anti-inflammatory efficacy profile may dampen the impact of the systemic inflammatory response mediated by IFN-alpha.

ENDPOINTS
Objective Endpoint related to objective
To describe the effect of combination therapy with IFN-alpha (Pegasys, PegIntron) and JAK1-2-inhibitor treatment (ruxolitinib) Change in hematological parameters (Hb, hematocrit, white blood cell count, platelet count, LDH, reduction in JAK2V617-mutation allele burden) and
Change in quality of life score from baseline (MPN-SAF)
To investigate whether additional treatment with JAK1-2-inhibitor (ruxolitinib) to patients who show intolerance (due to adverse events) during treatment with interferon-alpha (IFN-alpha) (Pegasys, PegIntron) can improve the efficacy based on individual contribution of the two agents regarding that the JAK1-2 inhibitor through its very potent anti-inflammatory effect profile may dampen the systemic inflammatory response mediated by IFN-alpha. Difference in number of IFN-related adverse events compared to matched group in the Dahlia study
The compliance to the treatment, as measured by the number of patients who discontinue ruxolitinib/IFN for AE, and the safety of the treatment, as measured by the number and the type of SAE during Ruxolitinib/IFN alpha treatment.
To investigate whether additional treatment with JAK1-2-inhibitor (ruxolitinib) to patients who exhibit lack of efficacy of treatment (IFN-alpha) (Pegasys, PegIntron) can establish / re-establish treatment response regarding that the JAK1-2 inhibitor through its very potent anti-inflammatory effect profile may reduce / eliminate the systemic inflammation response - mediated by IFN-alpha and MPN disease per se – and thereby potentially may facilitate the inhibition of clonal expansion (by down-regulation of inflammatory cytokines - TNF-alpha 2, IL-6 etc. - and perhaps through an enhancement of IFN-alpha's effects on the immune cells of interest for intact "Tumor Immune Surveillance "(for example, NK cells, dendritic cells, cytotoxic T cells, regulatory T cells)
Number of patients with complete hematological response compared to matched group in DAHLIA study
To investigate whether combination therapy with JAK1-2 inhibitor results in elimination of interferon antibodies (IFN-ab) and thus induction of efficacy in treatment refractory patients with evidence of antibody formation to recombinant interferon Level of interferon antibodies (IFN-ab) compared to baseline
