A Study of Ruxolitinib in Combination With Abemaciclib for the Treatment of Myelofibrosis

Conditions

Myelofibrosis Due to and Following Polycythemia Vera Ruxolitinib Abemaciclib 22-075

Quick Navigation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The study is being done to see if the combination of ruxolitinib and abemaciclib is a safe and effective treatment for people with primary or post-polycythemia vera/essential thrombocythemia myelofibrosis.

Inclusion Criteria	Exclusion Criteria
* Patients with PMF or post-PV/ET MF requiring therapy and intermediate-1, -2 or high risk disease by the Dynamic International Prognostic Scoring System (DIPSS) , DIPSS-plus MIPSS7021 or MIPSS70-plus v2.0 if PMF and by the Myelofibrosis Secondary to PV and ET - Prognostic Model (MYSEC-PM) if post-PV/ET MF * Treated with ruxolitinib for ≥12 weeks with a stable dose for the preceding ≥4 weeks. Patients must be on a dose of ruxolitinib of 10mg or 15mg BID at the time of screening. * Evidence of inadequate response to ruxolitinib: Patients must have palpable splenomegaly ≥5 cm below the left costal margin at study entry AND/OR active MPN symptoms, as defined by the presence of one symptom score ≥5 or two symptom scores ≥3 using the screening symptom form * Age ≥ 18 years. * Eastern Cooperative Oncology Group (ECOG) performance status 0, 1 or 2. * Life expectancy of at least 24 weeks. * The patient has adequate organ function for all of the following criteria: * Hemoglobin Patients may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the investigator. Initial treatment must not begin earlier than the day after the erythrocyte transfusion * ANC ≥1.5 × 10\^9/L * Platelets ≥75 × 10\^9/L * Hepatic * Total bilirubin ≤1.5 × ULN * Patients with Gilbert's syndrome with a total bilirubin \>2.0 times ULN and direct bilirubin within normal limits are permitted. * ALT and AST ≤3 × ULN * Patients who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade ≤1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to start of therapy. A washout period of at least 21 days is required between last chemotherapy dose and start of combination therapy (with the exception of hydroxyurea, which may be continued until the day before dosing begins). Patients should not receive hydroxyurea while on treatment. * Patients who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and randomization * The effects of ruxolitinib and abemaciclib on the developing human fetus are unknown. To be eligible for the study, female subjects of childbearing potential (and their male partners) and men (and female partners) enrolled in the study should use two methods of effective contraception (hormonal and barrier method of birth control; abstinence) prior and during the study and also continue to use contraception for 4 months after completion of ruxolitinib and abemaciclib administration. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of ruxolitinib and Abemaciclib administration. * Ability to understand and the willingness to sign a written informed consent document.	* Prior therapy with CDK4/6 inhibitors. * The patient has received an experimental treatment in a clinical trial within the last 30 days or 5 half-lives, whichever is longer, prior to randomization, or is currently enrolled in any other type of medical research (for example: medical device) judged by the sponsor not to be scientifically or medically compatible with this study. * Concomitant treatment with other investigational agents for therapy of MF * Splenic irradiation within the 4 months preceding study treatment initiation. * Inadequate recovery from toxicity and/or complications from a major surgery before starting therapy. * Patients with active CNS leukemia. * Inability to swallow pills or GI conditions that would be expected to impair intestinal absorption. * History of allergic reactions attributed to ruxolitinib, abemaciclib or compounds of similar chemical or biologic composition. * The patient has active systemic bacterial infection (requiring intravenous \[IV\] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C \[for example, hepatitis B surface antigen positive\]. Screening is not required for enrollment. * Patients with ≥ 10% circulating or bone marrow blasts. * Pregnancy and lactation. * The patient has serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment \[e.g. estimated creatinine clearance \<30ml/min\], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea). * The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. * Patients receiving any medications or substances that are strong inhibitors or inducers of CYP3A that cannot be discontinued. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated list such as http://medicine.iupui.edu/clinpharm/ddis/; medical reference texts such as the Physicians' Desk Reference may also provide this information. * Unwillingness to be transfused with blood components. * Inability to comprehend or unwilling to sign the informed consent form (ICF). * Other conditions that, in the opinion of the investigator, may compromise the achievement of the objectives of the study.
