ABC294640 in Treating Patients With Advanced Solid Tumors - Full Text View

Purpose

This phase I trial studies the side effects and best dose of ABC294640 in treating patients with advanced solid tumors. ABC294640 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Primary Outcome Measures:

Maximum tolerated dose (MTD) defined as highest dose of ABC294640 at which 0 or 1 patient of 6 experiences a DLT. [ Time Frame: Patients will be followed until the point in time when no more than 1 of 6 patients has a Dose Limiting Toxicity (DLT) in cycle 1, and expected 54 days. ] [ Designated as safety issue: Yes ]
MTD defined as the highest dose at which 0 or 1 patient of 6 experiences a DLT. The DLT rate will be estimated with its 95% confidence interval.
Safety assessed using the National Cancer Institute (NCI) Common Toxicity Criteria (CTC) version 4.0. [ Time Frame: Weekly during course 1, bi-weekly for all subsequent courses, and at the end of treatment study-- expected to occur at an average of 6 months from study start. ] [ Designated as safety issue: Yes ]
Assessed using the National Cancer Institute (NCI) Common Toxicity Criteria (CTC) version 4.0. Adverse events (AEs) will be coded by body system and summary tables with incidence rates of adverse events will be generated. Descriptive statistics of AEs will be reported by doses and for subsets of patients with serious adverse events (SAEs), patients who discontinue due to AEs, and patients with related AEs.

Secondary Outcome Measures:

Pharmacodynamic parameters for sphingosine kinase-2 inhibitor ABC294640 [ Time Frame: Days 1 and 28 of cycle 1 collected at prior to dose, 1, 2, 4, 8, 12, 24 hours post drug administration. ] [ Designated as safety issue: No ]
Area under the drug concentration over time curve (AUC), maximum concentration, minimum concentration, and time to maximum concentration will be calculated for each subject.
Pharmacodynamic parameters for sphingosine kinase-2 inhibitor ABC294640 [ Time Frame: Weekly during course 1, bi-weekly for all subsequent courses, and at the end of treatment study ] [ Designated as safety issue: No ]
Pharmacodynamic parameters for ABC294640 action will include measurement of plasma levels of S1P, including absolute concentration at each sampling time and chance from baseline concentration at each sampling time after drug administration.
Tumor response rate [ Time Frame: Every 8 weeks ] [ Designated as safety issue: No ]
All patients who have measureable disease according to RECIST 1.1, received at least one cycle of treatment, and have had disease re-evaluated will be included.

Estimated Enrollment:	45
Study Start Date:	August 2011
Estimated Primary Completion Date:	December 2013 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Treatment (enzyme inhibitor therapy) Patients receive sphingosine kinase-2 inhibitor ABC294640 PO BID on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.	Drug: sphingosine kinase-2 inhibitor ABC294640 Given PO Starting dose of ABC294640 250 mg once on day on Days 1-28 of each 28-day cycle. Subsequent cohort doses (if reached) are as follows: 250 BID, 500 BID, 750 BID, 1,000 BID, 1,500 BID, 2,000 BID, 2,500 BID Other Name: SK2 inhibitor ABC294640

Detailed Description:

PRIMARY OBJECTIVES:

I. To assess safety and determine the maximum tolerated dose (MTD) and the dose limiting toxicities (DLT) of ABC294640 (sphingosine kinase-2 inhibitor ABC294640) in patients with solid organ tumors. (Part I) II. To assess the safety and tolerability of ABC294640 at the MTD in an expanded cohort of pancreatic cancer patients. (Part II)

SECONDARY OBJECTIVES:

I. To establish the dose of ABC294640 recommended for future phase II protocols. (Part I) II. To describe the pharmacokinetics of ABC294640 in patients with solid organ tumors. (Part I) III. To describe the effects of ABC294640 on plasma levels of sphingosine 1-phosphate in patients with solid organ tumors. (Part I) IV. To assess antitumor activity of ABC294640 in patients with solid organ tumors by objective radiographic assessment using Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria. (Part I) V. To describe the pharmacokinetics of ABC294640 in pancreatic cancer patients. (Part II) VI. To describe the effects of ABC294640 on plasma levels of sphingosine 1-phosphate in pancreatic cancer patients. (Part II) VII. To assess antitumor activity of ABC294640 in pancreatic cancer patients by objective radiographic assessment using RECIST 1.1 criteria. (Part II)

OUTLINE: This is a dose-escalation study.

Patients receive sphingosine kinase-2 inhibitor ABC294640 orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up monthly for 1 year.
