Eltrombopag in Myelodysplastic Syndrome (MDS) Patients With Thrombocytopenia

November 3, 2022 updated by: H. Lee Moffitt Cancer Center and Research Institute

A Sequential Two-Stage Dose Escalation Study to Evaluate the Safety and Efficacy of Eltrombopag in Myelodysplastic Syndrome (MDS) Patients With Thrombocytopenia Who Progressed or Are Resistant to Hypomethylating Agents

The purpose of this study is to evaluate the safety and efficacy of eltrombopag in people who have myelodysplastic syndrome (MDS) with thrombocytopenia who have progressed or are resistant to decitabine or azacitidine. (These are the only 2 drugs approved by the U.S. Food and Drug Administration [FDA] which can improve platelet counts). The investigators (the study doctor, study staff, and sponsor) want to find out what effects, good or bad, eltrombopag (study drug) may have on people with low platelet counts due to MDS. The investigators will also be testing how well eltrombopag may work at different doses in these diseases.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Study was originally designed as a Phase I/II but was terminated during the Phase I portion due to lack of efficacy

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Confirmed diagnosis of MDS using the World Health Organization (WHO) classification or a diagnosis of WHO Myelodysplastic/ Myeloproliferative Neoplasm (MDS/MPN) or MDS refractory anemia with excess blast in transformation (RAEB-t) by French American British (FAB) classification (AML with 20-30% myeloblasts by WHO classification).
  • All prognostic risk groups according to the International Prognostic Scoring System (IPSS) and MD Anderson Risk Model
  • At least one prior HMTA treatment with either azacitidine or decitabine and subsequent loss of response to HMTA, progression while on HMTA, or no response to HMTA, defined as failure to achieve at least HI after 4 cycles of treatment
  • The mean of the two platelet counts taken within 1 month prior to dosing must be ≤50 x 10^9/L. Platelets counts must reflect pre-transfusion trough results or be obtained no sooner than 1 week after platelet transfusion to assure stable baseline platelet count. The platelet count obtained should be outside the expected nadir of prior therapies.
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-2 (Karnofsky >60%
  • Adequate liver function, as evidenced by total serum bilirubin ≤ 1.5 times the upper limit of normal (patients with Gilbert's disease are eligible, provided intermittent indirect hyperbilirubinemia), aspartic transaminase (AST) or alanine transaminase (ALT) ≤ 3 times the upper limit of normal (ULN).
  • A serum creatinine concentration ≤ 2 x ULN
  • Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
  • Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

  • Clinically significant bleeding within 4 weeks of screening defined as any grade 3 or grade 4 bleeding by WHO Bleeding Scale or any gastrointestinal (GI) bleeding or intracranial hemorrhage
  • Splenic enlargement extending >8 cm below the left costal margin
  • Myelodysplastic syndrome with fibrosis (MF 3)
  • Received Anti-Thymocyte Globulin (ATG) within 6 months of screening
  • Received immunomodulating agents, histone deacetylase inhibitors, cyclosporine, or mycophenolate within 4 weeks of screening
  • History of treatment with eltrombopag, romiplostim or other thrombopoietin receptor (TPO-R) agonists
  • Concurrent use of granulocyte colony-stimulating factor (G-CSF) except for the short-term management of neutropenic infection. Stable doses of erythropoietin stimulating agents or corticosteroids that were being administered prior to screening are allowed.
  • Treatment with an investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of study medication.
  • Pregnant or breast feeding
  • Current alcohol or drug abuse
  • Known Hepatitis B or Hepatitis C infection or liver cirrhosis
  • Uncontrolled current illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • At eltrombopag dose levels 200 mg and above cohorts, participants with a QT corrected for heart rate (QTc) > 480 msec at screening, if other drugs known to cause prolonged QT are stopped an EKG documenting QTc below 480 msec is required.
  • History of metastatic malignancy in the preceding 2 years
  • Known Human Immunodeficiency Virus (HIV) positive patients. These patients are excluded because they may have morphologic dysplasia which mimics MDS but is not true MDS Tand thrombocytopenia could be multifactorial secondary to HIV infection or to medications.
  • Receiving, or planning to receive, any of the medications listed in the Prohibited Medications section during conduct of the study.
  • East Asian patients (Chinese, Japanese, Taiwanese, and Korean ancestry) are excluded during stage I of the study (dose escalation phase) due to the different pharmacogenomics in this patient population.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Maximum Tolerated Dose (MTD)
Time Frame: 24 months
Determine the maximum tolerated dose (MTD) of eltrombopag for the treatment of thrombocytopenia in participants with MDS who have either progressed or are resistant to Hypomethylating Agents (HMTA).
