  • Clearing of circulating peripheral blasts [ Time Frame: By 35 days from start of most recent course of chemotherapy ] [ Designated as safety issue: No ]
  • Attainment of aplastic bone marrow [ Time Frame: By 35 days from start of most recent course of chemotherapy ] [ Designated as safety issue: No ]
    Scatterplots, means, standard deviations, and confidence intervals will be constructed to compare responders and non-responders.

  • Achievement of complete or partial remission [ Time Frame: By 35 days from start of most recent course of chemotherapy ] [ Designated as safety issue: No ]
    Scatterplots, means, standard deviations, and confidence intervals will be constructed to compare responders and non-responders.

  • Correlation between treatment-related toxicities with pharmacokinetic studies [ Time Frame: By 35 days from start of most recent course of chemotherapy ] [ Designated as safety issue: No ]
    Scatterplots, means, standard deviations, and confidence intervals will be constructed to compare responders and non-responders.


Enrollment: 40
Study Start Date: December 2004
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (ispinesib)

Induction chemotherapy: Patients receive SB-715992 IV over 1 hour on days 1-3. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Consolidation chemotherapy: Patients achieving CR, PR, or SD after induction chemotherapy receive up to 4 additional courses of SB-715992 beyond CR, PR, or SD.

Cohorts of 3-6 patients receive SB-715992 until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. At least 9 patients are treated at the MTD.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine the maximum tolerated dose (MTD) of SB-715992 given as a daily x 3 infusion in patients with acute leukemia.

II. To obtain pharmacokinetic studies of SB-715992 given on a 3 consecutive day schedule every 3 weeks.

III. To describe treatment-related and dose-limiting toxicities of SB-715992 in patients with acute leukemia.

IV. To describe the anti-leukemia activity of SB-715992. V. To correlate treatment-related toxicities with pharmacokinetic studies of SB-715992.

SECONDARY OBJECTIVES:

I. To validate KSP as the major target of SB-715992 by determining the impact of drug treatment on cytoskeletal morphology in peripheral blood mononuclear cells and circulating leukemic blasts.

II. To determine the expression of tubulin isoforms and KSP in leukemic blasts and explore possible relationships between gene expression and response to SB-715992.

OUTLINE: This is a dose-escalation, multicenter study.

Induction chemotherapy: Patients receive SB-715992 IV over 1 hour on days 1-3. Treatment repeats every 21 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Consolidation chemotherapy: Patients achieving complete response (CR), partial response (PR), or stable disease (SD) after induction chemotherapy receive up to 4 additional courses of SB-715992 beyond CR, PR, or SD.

Cohorts of 3-6 patients receive SB-715992 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. At least 9 patients are treated at the MTD.

Patients are followed for 6 weeks.

PROJECTED ACCRUAL: Approximately 15-30 patients will be accrued for this study within 7.5-15 months.

  • Patients may not have received any other investigational agents within 28 days of study entry
  • Patients may not receive any other anti-cancer therapy (cytotoxic, biologic, radiation, or hormonal other than for replacement) while on this study
  • Prohibited medications: SB-715992 is a moderate to significant in vitro inhibitor of CYP3A4; the following lists of medications/substances are moderate to significant inhibitors/inducers of CYP3A4 that, if administered concomitantly with SB-715992, may alter study drug exposure; the use of these medications/substances within 14 days (>= 6 months for amiodarone) prior to the administration of the first dose of SB-715992 through discontinuation from the study is prohibited

    • Inhibitors of CYP3A4:

      • Antibiotics: clarithromycin, erythromycin, troleandomycin
      • Antifungals: itraconazole, ketoconazole, fluconazole (doses > 200 mg/day), voriconazole
      • Antidepressants: nefazodone, fluvoxamine
      • Calcium channel blockers: verapamil, diltiazem
    • Miscellaneous: amiodarone*, grapefruit juice, bitter orange; *use of amiodarone within 6 months prior to the administration of the first dose of SB-715992 is prohibited

  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to SB-715992
  • Uncontrolled intercurrent illness including, but not limited to ongoing or active or poorly controlled infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, poorly controlled pulmonary disease or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients with pre-existing neuropathy of grade 2 or higher are not eligible to participate
  • Pregnant women are excluded from this study because SB-715992 is a mitotic inhibitor with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with SB-715992, breastfeeding should be discontinued if the mother is treated with SB-715992
  • Patients with immune deficiency are at increased risk of lethal infections when treated with marrow-suppressive therapy; therefore, HIV-positive patients are excluded from this study
