Effect of 2-h Infusion of ON 01910.Na in Ovarian Cancer Patients

• Status: Completed
• Trial end date: 2011-07-01
• Target enrollment: 0
• Participant gender: Female

Summary

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.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

3. Requirement for steroids.

4. Clinical symptoms of brain metastases.
