Phase I/II, Study of Selective Inhibitor of Nuclear Export (SINE) Selinexor (KPT-330) + Sorafenib in Acute Myeloid Leukemia

Completed · Phase 1/Phase 2

Conditions studied: Leukemia, Acute Myeloid Leukemia

In brief

There are 2 parts to this study: Part 1 (dose escalation) and Part 2 (dose expansion). The goal of Part 1 of this clinical research study is to find the highest tolerated dose of the combination of selinexor (KPT-330) and sorafenib (Nexavar) that can be given to patients with FLT3-ITD and -D835 mutated acute myeloid leukemia (AML) or FLT3-mutated high-risk myelodysplastic syndrome (MDS). The goal of Part 2 of this study is to learn if the dose found in Part 1 can help to control the disease. The safety of the drug combination will also be studied in both parts of this study. This is an investigational study. Sorafenib is FDA approved and commercially available to treat hepatocellular cancer. Selinexor is not FDA approved or commercially available. It is currently being used for research purposes only. The combination of selinexor and sorafenib to treat FLT3-mutated AML and high-risk MDS is investigational. The study doctor can explain how the study drugs are designed to work. Up to 52 participants will take part in this study. All will be enrolled at MD Anderson.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• FLT3-ITD and/or FLT3-D835 mutated patients 18 years of age or older with relapsed/ refractory AML (any number of relapses) including patients who may have been previously exposed to one or more FLT3-inhibitor therapies will be eligible for the phase I portion of this study.
• Phase II FLT3-ITD and/or FLT3-D835 mutated relapsed/refractory patients: Patients should have a diagnosis of AML (de novo or transformed from hematologic malignancies). Patients with high-risk myelodysplastic syndrome (MDS) (defined as having >/= 10% blasts in the bone marrow) or patients with Chronic Myelomonocytic Leukemia (CMML) (having >/= 10% blasts in the bone marrow) may also be eligible after discussion with Principal Investigator (PI). The patients should have one of the following features: 1. Patients with AML should have failed any prior induction therapy or have relapsed after prior therapy. 2. Patients with high-risk MDS or high-risk CMML should have failed any prior therapy for the MDS or CMML. 3. Patients with MDS or CMML who received therapy for the MDS or CMML and progress to AML are eligible at the time of diagnosis of AML regardless any prior therapy for AML. The World Health Organization (WHO) classification will be used for AML.
• Patients must be eligible for one of two cohorts: Cohort 1 (FLT3 and/or FLT3-D835 inhibitor failure cohort) in FLT3-ITD and/or FLT3-D835 mutated relapsed/refractory AML who have failed therapy with up to two prior salvage regimens (SCT or stem cell therapy for patients who previously underwent SCT/stem cell therapy in remission will not be considered a salvage regimen) and have previously been exposed at least one prior FLT3 inhibitor. Cohort 2 (FLT3 inhibitor naive cohort) in FLT3-ITD and/or FLT3-D835 mutated relapsed/refractory who have failed therapy with up to two prior salvage regimens (SCT or stem cell therapy for patients who previously underwent SCT/stem cell therapy in remission will not be considered a salvage regimen) with no prior exposure to any FLT3 inhibitor.
• Age >/=18 years
• Eastern Cooperative Oncology Group (ECOG) Performance Status </=2
• Patients should have estimated life expectancy of >3 months at study entry
• Adequate hepatic (serum total bilirubin </= 2.0 x upper limit normal (ULN) (or </= 3.0 x ULN if deemed to be elevated due to leukemia), alanine aminotransferase and/or aspartate transaminase </= 3.0 x ULN (or </= 5.0 x ULN if deemed to be elevated due to leukemia), and renal function (creatinine </= 2.0 mg/dL).
• Patients must provide written informed consent.
• In the absence of rapidly progressing disease, the interval from prior treatment to time of initiation of selinexor and sorafenib administration will be at least 2 weeks for cytotoxic agents or at least 5 half-lives for cytotoxic/noncytotoxic agents. The use of chemotherapeutic or anti-leukemic agents is not permitted during the study with the following exceptions: (1) intrathecal (IT) therapy for patients with controlled Central Nervous System (CNS) leukemia at the discretion of the PI and with the agreement of the Sponsor. Controlled CNS leukemia is defined by the absence of active clinical signs of CNS disease and no evidence of CNS leukemia on the most recent 2 simultaneous CSF evaluations. (2) Use of one dose of cytarabine (up to 2 g/m2) or hydroxyurea for patients with rapidly proliferative disease is allowed before the start of study therapy and for the first four weeks on therapy. These medications will be recorded in the case-report form.
• Baseline ejection fraction must be >/= 40%.
• Females must be surgically or biologically sterile or postmenopausal (amenorrheic for at least 12 months) or if of childbearing potential, must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment.
• Women of childbearing potential must agree to use an adequate method of contraception during the study and until 3 months after the last treatment. Males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment. Adequate methods of contraception include: Total abstinence when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy) or tubal ligation at least six weeks before taking study treatment. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment
• (Continued from Criteria 12) Male sterilization (at least 6 months prior to screening). For female patients on the study, the vasectomized male partner should be the sole partner for that patient Combination of any of the two following (a+b or a+c or b+c) Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception Placement of an intrauterine device (IUD) or intrauterine system (IUS) Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository
• (Continued from Criteria 13) In case of use of oral contraception, women should have been stable on the same pill before taking study treatment. Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction. Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.
