Brief Summary:

Primary Objective:

- to assess the pathological Complete Response (pCR) rate in the breast of patients treated in following combinations: SAR240550 twice-weekly + weekly paclitaxel, SAR240550 weekly+ weekly paclitaxel, and weekly paclitaxel single agent as calibrator.

Secondary objectives are:

  • pCR rate in the breast and axilla,
  • Radiological/clinical objective response rate (ORR), breast conservation rate, disease free survival (DFS), and overall survival (OS), in each treatment arm,
  • Safety profiles of study combinations and of the single agent reference treatment,
  • Molecular characteristics of the tumor tissue and peripheral blood mononuclear cells (PBMC) and any correlation between the biological activity of the study treatment and the disease outcome.

Based on data generated by BiPar/Sanofi, it is concluded that iniparib does not possess characteristics typical of the PARP inhibitor class. The exact mechanism has not yet been fully elucidated, however based on experiments on tumor cells performed in the laboratory, iniparib is a novel investigational anti-cancer agent that induces gamma-H2AX (a marker of DNA damage) in tumor cell lines, induces cell cycle arrest in the G2/M phase in tumor cell lines, and potentiates the cell cycle effects of DNA damaging modalities in tumor cell lines. Investigations into potential targets of iniparib and its metabolites are ongoing.

Condition or disease Intervention/treatment Phase
Breast Cancer Female Drug: paclitaxel Drug: Iniparib (SAR2405550 -BSI-201) Phase 2

Detailed Description:

Active study treatment will be given either as twice weekly administration (Day 1 and Day 4) or as weekly administration (Day 1) for a maximum of 24 infusions for Arm A and for a maximum of 12 infusions for Arm B. In all study arms, treatment will be given until definitive surgery, the first sign of disease progression, unacceptable toxicity or withdrawal of patient consent.

Definitive surgery will be performed within 2 to 4 weeks after the last dose of study treatment.

Patients who complete all the study treatment or who withdraw consent or experience intolerable toxicity will undergo surgery according to local practices.

The cut-off date for the primary analyses will be 30 days after the last study treatment administration or the date of the definitive surgery, whichever comes last.

The maximum follow up for each individual patient will be until death or 5 years after the definitive surgery date whatever happens first.

  3. Breast conservation rate [ Time Frame: at the time of definitive surgery ]
  4. Disease Free Survival rate (DFS) [ Time Frame: up to a maximum of 5 years after definitive surgery ]
  5. Overall Survival (OS) [ Time Frame: up to a maximum of 5 years after definitive surgery ]
  6. Safety parameters (number of patients AE, SAE or AEPM) [ Time Frame: up to a maximum of 5 years after definitive surgery ]
  7. Molecular-biological testing [ Time Frame: 2 or 3 timepoints during treatment period ]
