Study of SAR240550 (BSI-201) in Combination With Gemcitabine/Carboplatin, in Patients With Metastatic Triple Negative Breast Cancer

Breast Cancer, Metastatic Clinical Trial

Official title: Multicenter, Randomized, Open Label Study Evaluating a Poly(ADP-ribose) Polymerase-1(PARP-1) Inhibitor, SAR240550 (BSI-201), Administered Twice Weekly or Weekly, in Combination With Gemcitabine/Carboplatin, in Patients With Metastatic Triple Negative Breast Cancer (mTNBC)

Status Completed

Clinical Trial Summary

Primary Objective:

• To assess the objective response rate (ORR) of iniparib (SAR240550) administered as a 60min intravenous (IV) infusion twice weekly or weekly, in combination with gemcitabine/carboplatin chemotherapy regimen in patients with metastatic Triple Negative Breast Cancer (mTNBC).

Secondary Objectives:

• To assess the clinical benefit rate (CBR) defined as the rate of complete response (CR), partial response (PR) and stable disease (SD) lasting at least 24 weeks;

• To assess Progression-free survival (PFS) and the overall survival (OS);

• To assess the safety profile of each schedule of iniparib;

• To assess the biological activity in tumor tissue (substudy);

• To evaluate the pharmacokinetic (PK) profile of iniparib (substudy);

• To characterize molecular and biological profile of tumors (substudy);

• To assess the effect of iniparib on poly(ADP)-ribose (PAR) level in peripheral blood mononuclear cells (PBMC) (substudy).

Clinical Trial Description

The duration of the study for a patient includes a period for inclusion of up to 3 weeks. The patients may continue treatment until disease progression, unacceptable toxicity or consent withdrawal, followed by a minimum of 30-day follow-up after the last study treatment administration.

In case of discontinuation of study treatment, the patient will be considered as withdrawn from study treatment, and will be followed as planned for at least 30 days after the last administration of study treatment for safety purpose. In case of study treatment discontinuation without disease progression, efficacy data will be collected every 6 weeks until disease progression, death or end of study whatever comes first. After disease progression, the patient will be followed-up every 12 weeks (3 months) for overall survival until death or end of study.

The patients who benefit from the study treatment can continue until disease progression, toxicity or willingness to stop. ;
