Brief Summary:
The purpose of this Phase 2 portion of the study is to use the dose and schedule of RX-5902 identified in the phase 1 to treat subjects with triple negative breast cancer.

Condition or disease Intervention/treatment Phase
Solid Tumor Triple Negative Breast Cancer Drug: RX-5902 Phase 1 Phase 2

Detailed Description:
In this dose-finding, open-label, single-agent study of RX-5902, subjects will be treated for up to 6 cycles of therapy. RX-5902 will be administered orally daily for 3 weeks followed by 1 week of rest in each cycle. All subjects will be followed for at least 30 days after the last dose of study agent for safety.

  2. Changes in tumor size mm [ Time Frame: baseline and 24 weeks ]
  3. Time to progression (Phase 2) [ Time Frame: Baseline and at 4, 8, 12, 16 and 24 weeks ]
  4. Duration of response (Phase 2) [ Time Frame: Baseline and at 4, 8, 12, 16 and 24 weeks ]
  5. Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 [ Time Frame: 6 months ]

Other Outcome Measures:
  1. phosphorylated P68 by IHC [ Time Frame: baseline and 8 weeks ]
