This study will evaluate the effect of two dose levels of NUC-1031 (500 mg/m2 and 750mg/m2) in patients with ovarian cancer. The primary objective is to determine the anti-tumor activity of NUC-1031 at the selected dose level (500 mg/m2 or 750 mg/m2).

Official Title

A Phase II Open-Label Study of NUC-1031 in Patients With Platinum-Resistant Ovarian Cancer


Up to 20 patients will be treated at each dose in Part I of the study. In Part II of the study, one of the treatment dose levels will be selected for further evaluation. The dose selection will be based on clinical and laboratory assessments of patients recruited in Part I. Patients will only participate in either Part I or II. A total of 64 patients will be treated in Part I and Part II combined.

Eligible consenting patients will receive NUC-1031 by IV infusion on days 1, 8 and 15 of each 28-day cycle. Patients will continue to receive NUC-1031 until the occurrence of disease progression. Patients will undergo imaging every 8 weeks. After disease progression, patients will be followed for overall survival.
