This phase I trial studies the side effects and best dose of ganetespib when given with paclitaxel and trastuzumab in treating patients with advanced or metastatic human epidermal growth factor receptor 2 positive (HER2+) breast cancer. HER2+ describes cancer cells that have too much of a protein called HER2 on their surface. In normal cells, HER2 helps to control cell growth. When it is made in larger than normal amounts by cancer cells, the cells may grow more quickly and be more likely to spread to other parts of the body. Checking to see if a cancer is HER2+ may help plan treatment, which may include drugs that kill HER2+ cancer cells. Ganetespib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as trastuzumab, can block the ability of tumors to grow and spread. Giving ganetespib with paclitaxel and trastuzumab may be an effective treatment for patients with HER2+ breast cancer.

Primary Outcome Measures:
  • Maximum tolerated dose (MTD) of ganetespib when combined with paclitaxel and trastuzumab [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Objective Response Rate [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
    Defined as the percentage of patients who have achieved complete response or partial response assessed based on Response evaluation criteria in solid tumors 1.1 (RECIST 1.1).

  • Clinical benefit rate [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
    Defined as the percentage of patients who have achieved complete response, partial response, or stable disease for at least 24 weeks assessed based on RECIST 1.1.

  • Duration of response [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
    The duration of response is measured from the time of response to disease progression.

  • Progression-free survival (PFS) [ Time Frame: Up to 2 years ] [ Designated as safety issue: No ]
    The median time of progression-free survival will be calculated.

Other Outcome Measures:
  • PK parameters of paclitaxel (such as area under the curve and maximum concentration) [ Time Frame: Pre-dose, 0.5, 1, 1.5, 2, 4, 7, 21, 24, 27, and 31 hours ] [ Designated as safety issue: No ]
    Will be examined descriptively to evaluate the effect of ganetespib on the paclitaxel absorption.

Detailed Description:


I. To establish the safety, tolerability, maximum tolerated dose (MTD) and the recommended phase II dose of ganetespib plus paclitaxel in conjunction with trastuzumab in patients with HER2+ metastatic breast cancer (MBC).


I. To evaluate the possible effects of ganetespib on the pharmacokinetics (PK) of paclitaxel.

II. To make a preliminary assessment of the efficacy of the combination of ganetespib, paclitaxel and trastuzumab as measured by objective response rate (ORR), progression-free survival (PFS), duration of response, and clinical benefit rate (complete response + partial response + stable disease > 24 weeks).


Patients receive trastuzumab IV over 30 minutes on days 1, 8, 15, and 22, paclitaxel IV over 1 hour on days 1, 8, 15, and 22, and ganetespib intravenously (IV) over 1 hour on days 1, 8, and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 12 weeks.
