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.
Interventions
DRUGRQ-00000007
RQ-07 250 mg will taken orally, with or without food, each morning and evening, approximately 12 hours apart. Drug administration will be continuous. Every 21 day period will be considered one cycle of treatment.
DRUGGemcitabine
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 administered at 1000 mg/m2 IV over 30 minutes for 3 out of 4 weeks after appropriate pre-medications. Every 4 week period (28 days) will be considered one cycle.

Inclusion criteria
1. Histologically or cytologically confirmed breast, prostate or non-small cell lung cancer or other A tissue block, 10 unstained slides or fresh tissue biopsy is required. 2. At least 2 weeks should have elapsed since the last treatment and patients should have recovered from previous significant toxicity (i.e. to grade 1 or less). 3. ECOG Performance Status \<2. 4. Patient at least 18 years of age or older. 5. Adequate hematological function as defined by the protocol, section 4.1.5. 6.

Normal serum electrolytes (no \>grade 2 abnormalities), magnesium and phosphorus on the day of therapy. Correction of abnormalities is permitted. Adequate hepatic function per institutional standards (see exclusion). 8. All patients must be informed of the investigational nature of this study and must sign and give written informed consent. 9. Serum calcium, magnesium and potassium must be within normal limits. Supplementation to achieve normal values is permitted. 10. Patients who are potentially fertile and sexually active must be willing to utilize effective birth control. 11. Patients with CNS metastases which are/were symptomatic must have completed therapy (surgery, gamma knife, XRT) and be neurologically stable. 12. Patients must have \> or = 4 circulating tumor cells
Exclusion criteria
1. Patients must not have serious infection or other serious underlying medical condition which would impair the ability of the patient to receive protocol treatment. 2. Current uncontrolled cardiac disease 3. Acute bacterial or fungal infection requiring intravenous antibiotics at the time of registration 4. Chronic Obstructive Pulmonary Disease exacerbation or other respiratory illness requiring hospitalization or precluding study therapy within 4 weeks of registration. 5.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Circulating Tumor Cells (CTC) | 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
| Measure | Time frame | Description |
|---|---|---|
| Myeloid Derived Suppressor Cell (MDSC) | Day 21 | The efficacy of the treatment drug RQ-07 will be assessed as a single agent and in combination with gemcitabine in breast cancer and lung cancer patients only. MDSC evaluation will be done via a blood sample collection |
