A Dose Escalation Study of Iniparib as a Single Agent and in Combination in Solid Tumors
A Phase 1/1b Dose Escalation Study Evaluating Iniparib (BSI201/SAR240550) as a Single Agent and in Combination With Chemotherapeutic Regimens in Patients With Solid Tumors

Primary Objective:

  • To assess the safety and the maximum tolerated dose(MTD) of iniparib as a single agent and in combination with chemotherapeutic regimens in patients with advanced solid tumors that are refractory to standard therapy.

Secondary Objectives:

  • To assess the antitumor effect of iniparib (per Response Evaluation Criteria in Solid Tumors [RECIST]) Version 1.1 in patients with measurable disease.
  • To characterize iniparib (and its metabolites, if possible) pharmacokinetics.

Based on data generated by 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.

The duration of the study for an individual patient will include a period to assess eligibility (screening period) of up to 4 weeks (28 days), a treatment period of at least 1 cycle (3 weeks or 4 weeks depending on regimen) of study treatment, and an end-of-treatment visit at least 30 days following the last administration of study drug. However, treatment may continue until precluded by toxicity, progression, or death.

Patients will receive gemcitabine/carboplatin infusions once weekly (days 1 and 8). Iniparib will be administered for two weeks, followed by a 1week of rest in a 21-day cycle (weekly schedule: days 1 and 8; twice weekly schedule: days: 1, 4, 8 and 11).
    Interventions:

    • Drug: Carboplatin
  • Experimental: Iniparib/Paclitaxel
    Paclitaxel (P): Paclitaxel will be administered at the dose of 80 mg/m2 as a 60-minute intravenous infusion administered on days 1, 8, and 15 followed by a 1week of rest. Iniparib will be administered for three weeks, followed by 1week of rest in a 28-day cycle (weekly schedule: days 1, 8 and 15; twice weekly schedule: days 1, 4, 8, 11, 15 and 18).
    Interventions:
    • Drug: Iniparib (SAR240550-BSI-201)

    Pegylated liposomal doxorubicin (Doxil)/Carboplatin (PLD) : Doxil will be administered at 30 mg/m² as a 30min IV infusion and carboplatin AUC 4 as a 60min IV infusion on day 1 every four weeks. Iniparib will be administered for two weeks in a 28-day cycle (weekly schedule: days 1, and 8; twice weekly schedule: days 1, 4, 8, and 11).
    Interventions:

Inclusion criteria:

  • Capable of understanding and complying with the protocol requirements, and have signed the informed consent document
  • ≥18 years of age
  • Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
  • To have histological or cytological evidence of a diagnosis of cancer that is advanced and/or metastatic disease; that is refractory to standard therapy and/or therapies known to provide clinical benefit or for which no standard therapy exists
  • For phase 1b, patients for whom the backbone chemotherapy (dose and schedule) can be considered as a standard therapeutic regime for their cancer.
