Study of Metformin With Carboplatin/Paclitaxel Chemotherapy in Patients With Advanced Ovarian Cancer

NCT ID: NCT02312661

Last Updated: 2024-05-06

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 15 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-10-05
• Study Completion Date: 2017-11-30

Brief Summary

Molecularly targeted agents which inhibit the mammalian target of rapamycin (mTOR) pathway and/or circumvent p53 in the induction of apoptosis are exciting potential targets in ovarian cancer. Metformin is a biguanide, widely used in the treatment of type 2 diabetes mellitus, that has shown anti-cancer activity in preclinical studies. The main mechanism of metformin's effect is mTOR pathway inhibition and, in addition, it has been shown to circumvent p53-induced apoptosis making it an exciting, potentially effective drug in ovarian cancer.

Detailed Description

A phase Ib, single-centre, dose-escalation trial with a traditional escalation rule with fixed dose levels ("3 + 3" rule). The recommended phase II dose will be defined as the maximum predefined dose level at which 0 of 3 or ≤ 1 of 6 subjects experience a drug-related dose limiting toxicity (DLT) during cycle 1 and 2 of treatment. An estimated 10-20 patients will be required for this study.

Conditions
