E.2.1 | Main objective of the trial |
The objective of the Ruxo-BEAT trial is to assess the feasibility, safety, and efficacy of administration of ruxolitinib vs. best available therapy in patients with high-risk PV or high-risk ET.

E.2.2 | Secondary objectives of the trial |
•Safety of both regimens •The rate of complete clinicohematologic responses at month 12 & 24 as defined by Barosi et al. 2009 (with the clinical modification that splenomegaly assessment may be done by ultrasound or palpation) •To determine the complete response rate at month 6 as defined by Barosi et al. 2013 (revised ELN response criteria) •The efficacy as assessed by both the absence of phlebotomy (Hct <45%) and reduction in spleen size (palpable spleen that is reduced by > 50% from baseline measured by palpation or ultrasound) OR platelet count < 600 x 109/l (ET) at month 6 & 24 •The proportion of subjects achieving both durable absence of phlebotomy eligibility and durable spleen size reduction measured by palpation (PV) OR durable platelet count < 600 x 109/l (ET) (durable defined as > 3 months) (Barosi et al. 2009/2013) at month 6, 12 & 24 •The rate of overall clinicohematologic responses (CR+PR) according to both guidelines (Barosi et al. 2009 and 2013) at month 6 & 24 |

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Substudy to establish and prospectively validate cold-shock protein Ybx1 as diagnostic marker in MPN (August 10, 2016)
Concept and Specific Aims: We aim to prospectively validate Ybx1 as a diagnostic and putative prognostic marker for MPN (PV and ET) within the Ruxo-BEAT trial. Specific Aims (SA): SA1: Assessment of Ybx1 expression in diagnostic samples (bone marrow biopsies) from patients registered and screened for the Ruxo-BEAT trial. SA2: Analysis of Ybx1 mRNA expression in erythro-lysed peripheral blood samples derived from patients registered and screened for the Ruxo-BEAT trial. SA3: Correlation of immunohistochemical stainings (multiplied M-score) and mRNA expression with mutational status, disease burden, response to therapy and prognostic & clinical data. |

Patient must have adequate liver function as indicated by a total bilirubin, AST, and ALT ≤ 2 of the institutional upper limit of normal (ULN) value, unless directly attributable to the patient’s MPN 7.
