Clinical trial NCT02973711: A Study of Ruxolitinib in Combination With Nilotinib in Patients With Chronic Phase CML
Official title: A Phase I/II Study of Ruxolitinib in Combination With Nilotinib in Patients With Chronic Phase CML Who Have Achieved a Complete Hematologic Remission, Complete Cytogenetic Remission, and Major Molecular Remission, But Not a Complete Molecular Remission on a Tyrosine Kinase Inhibitor Alone.

Primary purpose: TREATMENT

Brief summary: This study combines two drugs (ruxolitinib and the tyrosine kinase inhibitor, nilotinib) in an attempt to eliminate the CML (Chronic Myeloid Leukemia) stem cell population and thus allow for the deepest and most durable response possible in patients with CML in chronic phase who have achieved a complete hematologic remission (CHR), complete cytogenetic remission (CCyR), and major molecular remission (MMR), but not a complete molecular remission (CMR). The study will look at safety and tolerability of ruxolitinib when combined with nilotinib in a phase I study and will help establish the MTD (Maximum Tolerated Dose) of ruxolitinib when combined with nilotinib. Once the optimal dose of ruxolitinib is established in the phase I setting, a phase II evaluation will seek to establish the efficacy of this combination.


Eligibility criteria: Inclusion Criteria:

* Patients ≥ 18 years of age
* ECOG (Eastern Cooperative Oncology Group) Performance Status 0, 1, or 2
* Must have a diagnosis of Philadelphia chromosome positive (Ph+) chronic myeloid leukemia (CML) in chronic phase, with no previous evidence of accelerated or blast-phase disease.
* Must be actively receiving treatment for their CML with a tyrosine kinase inhibitor (TKI): imatinib, dasatinib, nilotinib or bosutinib, and must be on stable dose for \> 1 year.
* Must have an ongoing complete hematologic response (CHR) on a TKI
* Must have an ongoing complete cytogenetic response (CCyR) on a TKI
* Must be in a major molecular remission (MMR) on a TKI for a minimum of 1 year leading up to enrollment.
* Adequate end organ function
* Adequate electrolytes
