Study Overview
Brief Summary
This is a phase II trial of (RQ-07) in advanced solid tumors in prostate, breast or non-small cell lung cancer.
Detailed Description
This is a phase II trial of (RQ-07) in advanced solid tumors in advanced prostate, breast or lung cancer. The purpose of this trial is to determine whether the administration of the study drug RQ-07 can decrease circulating tumor cells in advanced prostate, breast or lung cancer. Additionally, the study will evaluate whether the study drug may improve outcome in advanced prostate, breast or lungs cancer either by itself or when combined with gemcitabine, a standard chemotherapy drug. The combination of with gemcitabine will only be investigated after disease has worsened with the study drug RQ-07 by itself and only in patients with prostate or lung cancer.

Arms & Interventions
RQ-00000007 Alone
RQ-0000007 250 mg will be self-administered orally, with or without food, each morning and evening, approximately 12 hours apart.
Intervention: RQ-00000007 (Drug)
Gemcitabine
For patients with breast or lung cancer who have not previously received gemcitabine as part of their therapy or who may benefit from re-challenge with gemcitabine, gemcitabine will be given as an IV.
Intervention: RQ-00000007 (Drug)
Gemcitabine
For patients with breast or lung cancer who have not previously received gemcitabine as part of their therapy or who may benefit from re-challenge with gemcitabine, gemcitabine will be given as an IV.
Intervention: Gemcitabine (Drug)
Outcomes
Primary Outcomes
Circulating Tumor Cells (CTC)
Time Frame: Day 21
The efficacy of the treatment drug will be assessed by the reduction of the number of CTCs. Blood sample collection will be done to assess CTCs.
Secondary Outcomes
- Myeloid Derived Suppressor Cell (MDSC)(Day 21)
