Effect of 2-h Infusion of ON 01910.Na in Ovarian Cancer Patients
ON 01910.Na has undergone preclinical and clinical phase I studies showing activity in patients with progressing ovarian cancer resistant to platinum-based chemotherapies. This study will look at a larger population of patients to determine whether treatment with ON 01910.Na has an effect on progression free survival rates in patients with platinum-resistant ovarian cancer. ON 01910.Na will be given as an intravenous infusion over 2 hours on days 1, 4, 8, 11, 15, and 18 of a 28-day cycle. Patients will be treated for 6 or more cycles.

- Progression Free Survival [ Time Frame: 6 months ] [ Designated as safety issue: No ]Progression-free survival, defined as the number of days from the first day of study drug dosing to the day of documented disease progression or death, as assessed using RECIST (Response Evaluation Criteria in Solid Tumors) guidelines according to Therasse P, Arbuck SF, Eisenhauer EA, et al. (2000) J Natl Cancer Inst. 92:205-216. Progressive disease is defined as at least a 20% increase in the sum of the longest diameter (LD)of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions.
- Number of Adverse Events [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]The number of adverse events and their severity rating will be classified according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events, version 3.0.

Experimental: ON 01910.Na
3200 mg ON 01910.Na administered intravenously over 2 hours on days 1, 4, 8, 11, 15, and 18 of 28-day cycle
Drug: ON 01910.Na
This is a Phase II single arm study of ON 01910.Na to be administered as a 2-hour infusion biweekly to patients with progressive ovarian cancer resistant to platinum-based therapy.
The primary objective is to evaluate progression-free survival (PFS). The secondary objectives are to document other measures of outcome [objective response rate (ORR), duration of response, duration of stable disease, and overall survival (OS)], and tolerability of study drug.
Thirty-seven (37) patients with progressive ovarian cancer resistant to platinum-based therapy will be enrolled in a single arm study and treated with ON 01910.Na administered as a 2-hour infusion on Days 1, 4, 8, 11, 15 and 18 of a 28-day cycle. Patients will be treated until disease progression or withdrawal for other causes (unacceptable toxicity, patient or investigator decision) with ON 01910.Na. Toxicity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v3.0). Progression-free survival, objective response, duration of response, and duration of stable disease will be assessed using RECIST (Response Evaluation Criteria in Solid Tumor) guidelines, as well as overall survival. Grades 3 and 4 hematologic toxicities, grade >2 non-hematologic toxicities will be monitored. A futility analysis will be performed after 17 evaluable patients are enrolled and evaluated for overall objective response. If 3 or fewer objective response (CR and PR) are observed, the study will be closed to further accrual and deemed futile. An extension study for an additional 25 weeks with complete monitoring will be considered for patients who have not progressed by week 25.
The ON 01910.Na dose to be used in this study (2-hour infusions of 2400 or 3200 mg twice weekly for 3 weeks of a 4-week cycle) was selected based on the maximum tolerated doses and activities documented in phase 1 protocols.
