|Official title||A Phase I Trial of Oral Metronomic Topotecan in Combination With Oral Pazopanib Utilizing a Daily Dosing Schedule to Treat Recurrent or Persistent Gynecologic Tumors|
|Principal investigator||Todd D Tillmanns, MD|
|Description||This is a Phase 1, dose-escalation study in female patients with recurrent or persistent gynecologic tumors. The study will include a Screening Phase, a Treatment Phase and a Followup Phase. In the Screening Phase the subject's eligibility for study participation will be determined; this phase can last up to 28 days. The Treatment Phase will begin when the subject starts study treatment and will continue until the subject is removed from study treatment. The Follow-up Phase will last for 30 days after the subject ends study treatment. The study will be conducted at approximately 1 site and will include approximately 41 evaluable patients. Treatment cycle length is 28 days. Radiologic imaging will be repeated after every 2 cycles of treatment.|
