Sorafenib and Low Dose Cytarabine in Older Patients With Acute Myeloid Leukemia or High-Risk Myelodysplastic Syndrome

August 3, 2023 updated by: NCIC Clinical Trials Group

A Phase I/II Study of Sorafenib (BAY 43-9006) in Combination With Low Dose ARA-C (CYTARABINE) in Elderly Patients With AML or High-Risk MDS

RATIONALE: Sorafenib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the cancer. Drugs used in chemotherapy, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with cytarabine may kill more cancer cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of giving sorafenib together with cytarabine and to see how well it works in treating older patients with acute myeloid leukemia or high-risk myelodysplastic syndrome.

Detailed Description

OBJECTIVES:

  • To determine the recommended dose of sorafenib tosylate and cytarabine when given in combination to elderly patients with acute myeloid leukemia or high-risk myelodysplastic syndromes who are not suitable for intensive chemotherapy. (Phase I)
  • To determine the safety, tolerability, toxicity profile, and dose-limiting toxicities in patients treated with this regimen. (Phase I)
  • To estimate the efficacy (as measured by complete response rate) in patients treated with this regimen. (Phase II)
  • To describe the toxic effects and overall response rate (complete and partial) in patients treated with this regimen. (Phase II)
  • To evaluate potential correlates of response in translational research studies including FLT-3 internal tandem duplications and point mutations in blasts. (Phase II)

OUTLINE: This is a multicenter study.

  • Phase I: Patients receive oral sorafenib tosylate twice daily on days 2-28 and cytarabine subcutaneously twice daily on days 1-10 at the dose level assigned at registration. Doses of both drugs will be escalated and the recommended doses for the combination will be determined. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients who respond to treatment will receive 2 cycles after response criteria are met.
  • Phase II: Patients receive sorafenib tosylate and cytarabine as in phase I at the recommended doses for the combination determined in phase I.

Bone marrow (or blood) samples are collected at baseline and at the end of each course of study treatment. Baseline samples are analyzed for mutational status of FLT-3 (i.e., internal tandem duplication [ITD] and point mutations).

After completion of study treatment, patients are followed at 4 weeks and then every 3 months thereafter until progression and toxicities resolve.

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
