SB-715992 in Treating Patients With Advanced or Metastatic Colorectal Cancer

February 13, 2015 updated by: National Cancer Institute (NCI)

A Randomized Phase II Non-Comparative Study of SB-715992 Given Weekly or Every Three Weeks in Advanced or Metastatic Colorectal Cancer

This randomized phase II trial is studying how well SB-715992 works in treating patients with advanced or metastatic colorectal cancer. Drugs used in chemotherapy, such as SB-715992, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the objective response rate in patients with advanced or metastatic colorectal cancer treated with SB-715992 once a week for 3 weeks, every 28 days and SB-715992 once every 21 days.

SECONDARY OBJECTIVES:

I. To determine the time to tumor progression, progression free and overall survival of patients and toxicity in patients with advanced or metastatic colorectal cancer treated with SB-715992 once a week for 3 weeks, every 28 days and SB-715992 once every 21 days.

II. To characterize the population pharmacokinetic (PK) parameters of SB-715992 including an assessment of significant covariates on SB-715992 PK and an assessment of the potential relationships between the pharmacokinetics of SB-715992 and relevant safety and efficacy endpoints.

IV. To examine cytoskeletal morphology changes in response to SB-715992 in peripheral blood mononuclear cells and tumors by fluorescent immunohistochemistry.

V. To evaluate mRNA expression of betaΙΙΙ-tubulin and KSP in archival tumor tissue.

VI. To determine the frequency of genomic polymorphisms in genes targeted by SB-715992 (measured in peripheral blood mononuclear cells) and to assess whether germline polymorphisms (DNA) of genes targeted by SB-715992 (KSP inhibitor) are associated with toxicity and clinical outcome in patients with colorectal cancer. Further, whether genes involved with the metabolism (CYP3A4) and resistance (MDR1) affect the outcome in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive SB-715992 IV over 1 hour on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive SB-715992 IV over 1 hour on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 2 years, and then annually thereafter.

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
Objective Response (CR or PR) as Determined by the RECIST Criteria
Time Frame: Up to 5 years
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR
Up to 5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Progression-free Survival
Time Frame: From the date of registration to the date of documented PSA progression, assessed up to 6 months
Will be estimated using the product-limit method of Kaplan and Meier by arm. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
From the date of registration to the date of documented PSA progression, assessed up to 6 months
Overall Survival
Time Frame: From the date of registration to the date of death, assessed up to 12 months
Will be estimated using the product-limit method of Kaplan and Meier by arm.
From the date of registration to the date of death, assessed up to 12 months
