I. To explore the effects of the combination therapy of pevonedistat and ruxolitinib on downstream signaling pathways (including nuclear factor kappa-light-chain-enhancer of activated B cells [NF-kappaB]) using mass cytometry.
II. To measure cytokine levels as biomarkers of inflammatory cytokine signaling and their response to treatment with pevonedistat and ruxolitinib.
III. To identify genetic alterations associated with response to pevonedistat and ruxolitinib therapy and to determine the effect of the combination therapy on clonal hierarchy via genomic analysis.
OUTLINE: This is a phase I, dose-escalation study of pevonedistat.
Participants receive pevonedistat intravenously (IV) over 60 minutes on days 1, 3, and 5, and ruxolitinib per standard of care. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up at 30 days, 12 weeks, and then every 6 months for up to 5 years.
