Summary

This is a multi-center, open-label study designed to evaluate TTI-622 administered in combination with Pegylated liposomal doxorubicin in patients with platinum-resistant ovarian cancer. Approximately 50 patients will be enrolled in the study (this includes two phases, the Dose Escalation and Dose Expansion).

Description

Pegylated liposomal doxorubicin (PLD) is a standard treatment option for patients with platinum-resistant ovarian cancer who are not candidates for chemotherapy in combination with bevacizumab. However, despite being consider a standard treatment option, the clinical benefit of chemotherapy for this patient population is small. The goal of this clinical trial is to improve upon the activity of PLD in a safe manner to provide a more effective therapeutic option for this group of patients.

TTI-622-02 is a multi-center, open-label study designed to evaluate TTI-622 administered in combination with PLD in patients with platinum-resistant ovarian cancer and for whom PLD is a reasonable treatment option. The first portion of the study will evaluate the safety of increasing dose levels of TTI-622 in combination with PLD at 40 mg/m2 in patients with platinum-resistant EOC, including ovarian, peritoneal and fallopian tube malignancy, and establish a combination regimen for further evaluation in a dose expansion cohort. The study will consist of a 28-day screening period, a treatment period in which patients will receive TTI-622 in combination with PLD in 28-day cycles until documentation of objective disease progression or development of unacceptable toxicity, and a long-term follow-up period to assess overall survival.
