A Study of NK012 in Patients With Advanced, Metastatic Triple Negative Breast Cancer

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00951054
Recruitment Status : Completed
First Posted : August 4, 2009
Last Update Posted : February 16, 2015

Brief Summary:
The purpose of this study is to determine whether NK012 is safe and effective in the treatment of advanced and metastatic triple negative breast cancer.

Condition or disease Intervention/treatment Phase
Triple Negative Breast Cancer Drug: NK012 Phase 2

Detailed Description:
This is a Phase II, open label, single arm, multicenter study of NK012 in patients with locally advanced non-resectable and metastatic breast cancer with ER-negative, PR negative and HER2-negative phenotype. NK012 will be administered by infusion over 30 minutes once every 28 days (on Day 1 of each cycle). Patients will be screened for UGT1A1 polymorphism prior to enrollment in order to determine their starting dose.

Intervention Details:
  • Drug: NK012
    30 minute IV infusion once every 28 days. NK012 dose is 28 mg/m^2 (or 18 mg/m^2 depending on UGT1A1 polymorphism, with potential to dose escalate). Dose escalation cannot exceed 28 mg/m^2. Dosing will proceed until progression or unacceptable toxicity develops, or decision by patient or investigator to stop.

Primary Outcome Measures :
  1. Antitumor activity (overall response rate) of NK012 [ Time Frame: At baseline and after every 2 cycles; PR or CR must be confirmed no less than 4 weeks after the first response was recorded ]

Secondary Outcome Measures :
  1. Duration of response [ Time Frame: Monthly for 6 months after patient goes off study, then every 3 months thereafter ]
  2. Rate and duration of disease control [ Time Frame: Monthly for 6 months after patient goes off study, then every 3 months thereafter ]
  3. Time to disease progression [ Time Frame: Monthly for 6 months after patient goes off study, then every 3 months thereafter ]
  4. Toxicity profile of NK012 [ Time Frame: Duration of study, and up to 30 days after discontinuation ]

  • No less than one and no more than two prior chemotherapy regimens for advanced or metastatic disease.
  • Prior chemotherapy must have included a taxane either as part of an adjuvant regimen or as part of a metastatic disease regimen.
  • Interval from last dose of prior treatment to enrollment in this study must be at least 4 weeks for cytotoxic chemotherapy (exception: 6 weeks for nitrosoureas or mitomycin C), 5 half-lives for non-cytotoxic therapy (to be reviewed by the Medical Monitor to establish start date), and 4 weeks for monoclonal antibodies; patients must have recovered from all acute toxicities.
  • Measurable disease by RECIST.

Exclusion criteria:

  • Patient has Gilbert's Syndrome.
