Details and patient eligibility

About

This is a phase I, open-label, dose-escalation study of SB-485232. Subjects will receive SB-485232 administered as subcutaneous injections daily for 14 days. Dose escalation (enrollment into the next cohort) cannot occur until all three subjects have completed the previous cohort; 5 doses will be tested. An additional dosing regimen has been added to evaluate higher doses given twice weekly for 7 weeks. Therefore, the full evaluation period for each patient will extend out to approximately eleven weeks after the first day of SB-485232 dosing.

Inclusion criteria

Kinesin spindle protein (KPS) of greater than 70%.
No chemotherapy, immunotherapy, hormonal therapy, or biological therapy for cancer, radiotherapy, or surgical procedures (except for minor surgical procedures) within 4 weeks before beginning treatment with SB-485232 (6 weeks for nitrosoureas and mitomycin C).
Subjects must have recovered from toxicities (incurred as a result of previous therapy) sufficiently to be entered into a Phase I study.
Provide written informed consent.

Absolute neutrophil count greater than or equal to 1.5 X 109 /L.
Platelet count greater than or equal to 100 X 109 /L.
Partial thromboplastin time (PTT) and prothrombin time/international normalized ratio (PT/INR) within normal limits.
Serum creatinine less than or equal to 1.5 mg/dL (135 µmol/L) or estimated creatinine clearance greater than 50 mL/min (calculated by the Cockcroft-Gault Formula).
Total serum bilirubin less than or equal to 1.5 mg/dL.
Aspartate transaminase (AST) and alanine transaminase (ALT) less than or equal to 3 X ULN.
Sexually active males or females of reproductive capacity must use adequate contraception.
For subjects with a history of coronary artery disease, stress test must be within normal limits.
Subjects with a history of congestive heart failure, myocardial infarction or prior anthracycline chemotherapy must have a Multiple Gated Acquisition (MUGA) scan with a left ventricular ejection fraction of greater than 40%.

Exclusion criteria

Women who are pregnant or are breast-feeding.

Any serious medical or psychiatric disorder that would interfere with subject safety or informed consent.
Known leptomeningeal disease or evidence of prior or current metastatic brain disease.
Receiving concurrent chemotherapy, immunotherapy, radiotherapy, or investigational therapy.
Receiving concurrent systemic steroids.
History of ventricular arrhythmias requiring drug or device therapy.
Any severe concurrent disease or condition, including significant autoimmune diseases, which in the judgment of the principal investigator, would make the subject inappropriate for study participation.
Any unresolved or unstable serious toxicity from prior administration of another investigational drug.
Any investigational drug within 30 days or 5 half-lives (whichever is longer) preceding the first dose of SB-485232.
Psychological, familial, sociological, or geographical conditions that do not permit compliance with the study.
