A Study to Evaluate Safety and Efficacy of Selinexor in Combination With Ruxolitinib in Participants With Myelofibrosis
A Study to Evaluate Safety and Efficacy of Selinexor in Combination With Ruxolitinib in Participants With Myelofibrosis
This is a global, Phase 1/2, multicenter, open-label study to evaluate the safety and
efficacy of selinexor plus ruxolitinib in treatment nave myelofibrosis (MF) participants.
The study will be conducted in two phases: Phase 1a/1b and Phase 2. The Phase 1a of the study
will be dose escalation (non-randomized dose finding study) to determine the maximum
tolerated dose [MTD], recommended Phase 2 dose (RP2D), and evaluate safety and preliminary
efficacy and will follow a standard 3+3 design. The Phase 1b of the study will be dose
expansion (non-randomized efficacy exploration) at the determined RP2D to further assess the
safety and preliminary efficacy at this dose level. The Phase 2 (randomized efficacy
exploration) of the study will include MF participants who are treatment nave randomized 1:1
to receive the combination therapy of selinexor and ruxolitinib versus (vs) ruxolitinib
monotherapy.

Participants with untreated hepatitis C virus (HCV) are eligible there is documentation of negative viral load per institutional standard.
Participants with history of human immunodeficiency virus (HIV), are eligible if participants have cluster of differentiation 4 (CD4)+ T-cell counts 350 cells/microliter, negative viral load per institutional standard, and no history of acquired immunodeficiency syndrome (AIDS)-defining opportunistic infections in the last year.
Female participants of childbearing potential must have a negative serum pregnancy test at screening and agree to use highly effective methods of contraception throughout the study and for one month following the last dose of study treatment. Childbearing potential excludes: Age >50 years and naturally amenorrhoeic for >1 year, or previous bilateral salpingo-oophorectomy, or hysterectomy.
Male participants who are sexually active must use highly effective methods of contraception throughout the study and for one month following the last dose of study treatment. Must agree not to donate sperm during the study treatment period.
Participants must sign the written informed consent in accordance with federal, local and institutional guidelines.
Exclusion Criteria:

Received previous treatment with Janus kinase (JAK) inhibitors for MF (treatment with hydroxyurea for up to 2 weeks is allowed).
Previous treatment with selinexor or other exportin-1 (XPO1) inhibitors.
Impairment of gastrointestinal (GI) function or GI disease that could significantly alter the absorption of selinexor.

Major surgery
Uncontrolled (i.e. clinically unstable) infection requiring parenteral antibiotics, antivirals, or antifungals within 7 days prior to first dose of study treatment; however, prophylactic use of these agents is acceptable (including parenteral).
Any life-threatening illness, medical condition, or organ system dysfunction which, in the Investigator's opinion, could compromise the patient's safety, prevent the patient from giving informed consent, or being compliant with the study procedures.
