Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cytogenetic and/or molecular abnormalities associated with poor prognosis are quite common in patients with post-MPN AML. Although these findings likely contribute to the aggressive natural history and resistance to standard therapies, the genetic complexity of post-MPN AML may ultimately permit targeted therapy. Among these abnormalities, Janus kinase 2 (JAK2) has come to the fore recently. JAK2 V617F mutation, which is a hallmark of MPN, has been reported to be carried in approximately 35-50% of patients with post-MPN AML. We believe that this mutation be the most oncogenic driver in post-MPN AML.
In fact, BCR/ABL(+) acute leukemia (either blast crisis of CML or Ph+ ALL) is a similar disease model of the post-MPN AML. The clinical outcome of these disease has improved dramatically with ABL tyrosine kinase inhibitors (TKIs), such as imatinib, and nilotinib. It is a standard practice to give ABL TKI along with cytotoxic chemotherapy to BCR/ABL(+) acute leukemia. On the other hand, in BCR/ABL(+) acute leukemia, it is well known that single agent ABL TKI is not sufficient to control disease.
Likewise, ruxolitinib, which is a targeted agent for JAK2, have a great possibility to show efficacy for post-MPN AML when combined with cytotoxic agents. In a previous investigational study of ruxolitinib for refractory/relapsed leukemias, 2 of 3 AML patients evolving from MPN achieved complete remission with two cycles of ruxolitinib. In fact, many clinical trials are ongoing to investigate the therapeutic efficacy of ruxolitinib in post-MPN AML as a single agent.
However, considering a lesson from BCR/ABL(+) acute leukemia, ruxolitinib as a single agent may not be enough to cure these patients with post-MPN AML. Hence, for patients who are fit for intensive chemotherapy, it would easily conjectured that ruxolitinib in combination with cytotoxic chemotherapy would be better for these patients. Therefore, combination of ruxolitinib and cytotoxic chemotherapy would be an optimal treatment for post-MPN AML. From an epidemiologic perspective, it is true that post-MPN AML develops in elderly patients frequently. However, patients who fit for intensive chemotherapy are also encountered in the clinic for post-MPN AML not infrequently, justifying this study design. NCCN guideline also recommend intensive induction treatment for patients \> 60 years when there performance and comorbidity allows intensive treatment.
In this study, the therapeutic efficacy of ruxolitinib in combination with cytotoxic chemotherapy for post-MPN AML will be investigated. Unlike other clinical trials induction and consolidation treatment should include cytotoxic chemotherapeutic agents in addition to ruxolitinib.

Study Groups

Experimental arm
Ruxolitinib
Induction chemotherapy include combination of cytarabine (200mg/m2) and idarubicin (12mg/m2). Both 7+3 and 5+2 regimen is allowed according to age and performance status (PS) as follows;
* If Age \< 55 years and ECOG PS \< 2 : 7+3 regimen
* If Age ≥ 55 years or ECOG PS = 2 : 5+2 regimen
Ruxolitinib is administered for 14 days during induction/consolidation phase. After complete remission after induction, ruxolitinib is administered for the first 14 days during consolidation chemotherapy. Maximum 3 cycles of consolidation is recommended. In case of allogeneic stem cell transplantation (alloSCT), ruxolitinib is discontinued at the time of transplantation. After completion of consolidation, 2 years of ruxolitinib maintenance is planned. The follow-up period is from the time of enrollment until 24 months.
