The purpose of this study is to decide the best dose of the study drug, PU-H71, that can be given in combination with the standard chemotherapy drug, nab-paclitaxel (Abraxane).

Metastatic Breast Cancer Drug: PU-H71
Drug: Nab-paclitaxel
Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Intervention Model Description:

This is an open-label, phase Ib study of PU-H71 plus nab-paclitaxel (Abraxane) in patients with HER2-negative metastatic breast cancer (MBC).

Masking: No masking
Primary Purpose: Treatment

Official Title: A Phase 1b Study of PU-H71 With Nab-paclitaxel (Abraxane) in Patients With HER2-Negative Metastatic Breast Cancer

Primary Outcome Measures:

  • Maximum Tolerated Dose (MTD) [ Time Frame: 1 year ]

    The MTD will be the dose level at which 0/6 or 1/6 patients experience excessive toxicity with the next higher dose having at least 2/3 or 2/6 patients experiencing excessive toxicity. This means that if only 3 patients have been treated at a particular dose level and none of them had excessive toxicity, another 3 patients will be treated to verify that no more than 1 out of 6 patients had excessive toxicity.

Estimated Enrollment: 12
Actual Study Start Date: May 23, 2017
Estimated Study Completion Date: May 2018
Estimated Primary Completion Date: May 2018 (Final data collection date for primary outcome measure)
Experimental: PU-H71 With Nab-paclitaxel (Abraxane)

PU-H71 will be given as an intravenous infusion on Day 1 of a 21 day cycle and nab-paclitaxel will be administered at a dose of 260mg/m2 intravenously on Day 1. Both drugs will be administered on the same day, in sequence, with nab-paclitaxel being administered first followed by administration of PU-H71 as close as possible to 6 hours later (+/-1 hour). PU-H71 will be administered intravenously over a 1 hour period; nab-paclitaxel will be administered per standard guidelines as a 30-minute intravenous infusion.

  • Women of childbearing potential must agree and commit to the use of a highly effective method of contraception. Men must agree and commit to use a barrier method of contraception while on treatment and for 3 months after last dose of investigational products.

Exclusion Criteria:

  • Symptomatic brain or CNS metastases. Previously treated and stable CNS disease is allowed.
  • Any of the following for the treatment of cancer within 2 weeks of first study treatment: chemotherapy, immunotherapy, experimental therapy, or biologic therapy.
  • Radiation therapy (other than palliative radiation to bony metastases) as cancer therapy within 4 weeks prior to initiation of study treatment
  • Any major surgical procedure within 4 weeks of first study treatment
  • Prior treatment with Abraxane
  • Active liver disease, including viral or other hepatitis, or cirrhosis

  • Peripheral neuropathy of grade ≥ 2 per NCI CTCAE, Version 4.0, at the time of or within 3 weeks prior to the first study therapy
  • Other medications, or severe acute/chronic medical or psychiatric condition, or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results in the judgment of the investigator
  • History of an invasive second primary malignancy diagnosed within the previous 3 years, except for appropriately treated stage I endometrial or cervical carcinoma or prostate carcinoma treated surgically, and non-melanoma skin cancer.
