Combined Ruxolitinib and Enasidenib in Patients With Accelerated/Blast-phase Myeloproliferative Neoplasm or Chronic-phase Myelofibrosis With an IDH2 Mutation

Titre officiel

A Phase II Open-label Study of Combined Ruxolitinib and Enasidenib in Patients With Accelerated/Blast-phase Myeloproliferative Neoplasm or Chronic-phase Myelofibrosis With an IDH2 Mutation

Sommaire:

The presence of IDH mutation is associated with worse survival in patients with myelofibrosis. Moreover IDH mutations are among the most frequently encountered events in MPNs that have progressed to acute myeloid leukemia. Ruxolitinib, a JAK1/2 inhibitor, and enasidenib an IDH2 inhibitor are effective and tolerable treatments for patients with myelofibrosis (MF) and acute myeloid leukemia (AML), respectively. The study team hypothesize that the combination of these agents in patients with MPN with an IDH2 mutation will improve the overall clinical response to therapy.

Description de l'essai

Primary Outcome:

  • Proportion of MPN participants with response
Secondary Outcome:
  • Proportion of MPN participants with blast response
  • Proportion of MF-CP participants with any response
At this time, there is no standard medical treatment for MPN-AP/BP and most patients with accelerated and blast phase MPN do not respond well to treatment This is a phase II open-label study to evaluate the safety and efficacy of combined ruxolitinib and enasidenib in patients with accelerated/blast-phase myeloproliferative neoplasm or chronic phase myelofibrosis with high risk features and IDH2 mutation. Ruxolitinib (Jakafi/Jakavi) is FDA approved for myelofibrosis and was shown to reduce splenomegaly and improve symptoms. Enasidenib is a potent inhibitor of the IDH2 mutant enzyme and is FDA approved for relapsed refractory AML where it showed effectivity. Pre-clinical studies indicate increased disease mitigating effects with the combination of enasidenib and ruxolitinib. This study will enroll up to 32 patients. Ruxolitinib and enasidenib will be given orally in 28-day cycles.
