Inclusion Criteria:

* Patients must fulfill all of the following criteria to be eligible for study admission:
* Age greater than or equal to 18 years.
* Histologic or cytologic confirmation of lung, cervical, or ovarian cancer, following at least one standard treatment regimen, and for which there is no known standard therapy capable of extending life expectancy. Female patients with primary papillary carcinoma of the peritoneum and fallopian tube cancers will be included in the latter group, as the disease entities are closely associated with epithelial ovarian carcinoma, can be difficult to distinguish, have a similar epithelial origin, and are treated in an identical manner.
* Histologic or cytologic confirmation of renal cell carcinoma (clear cell, type 1 and type II papillary chromophobe, collecting duct and medullary). Patients should have received either sunitinib or sorafenib, unless deemed ineligible for treatment with either agent. In addition,patient should either: (a) have received IL-2; (b) have been evaluated for therapy with Interleukin-2 (IL- 2) and deemed to be ineligible; or (c) have been evaluated for therapy with IL2 and refused treatment.
* Performance status: Eastern Cooperative Oncology Group (ECOG) 0-2
* Life expectancy of 3 months or greater.
* Suitable candidate for receiving planned therapy as evidenced by screening laboratory assessments hematologic, renal hepatic, and metabolic functions, platelet count greater than or equal to 90,000/mL, absolute granulocyte count(AGC) greater than or equal to 1,500/mL, serum creatinine greater than or equal to 1,500/mL, serum creatine less than or equal to 1.5 mg/dl )or if greater than 1.5 a measured 24 hour creatinine clearance greater than or equal to 50 mL/min) and serum glutamic oxaloacetic transaminase (SGOT) less than or equal to 2.5 x normal limit (NL) and bilirubin less than or equal to 1.5 x NL (in patients with clinical evidence of Gilbert's disease,less than or equal to 3 x NL).
* Patients must be greater than or equal to 4 weeks prior radiation or chemotherapy, greater than 2 weeks from hormonal therapy; greater than 4 weeks from prior experimental therapy; greater than 6 weeks from mitomycin C; and greater than 8 weeks from prior UCN01 treatment.
* No serious intercurrent medical illness.
* Measurable disease by radiographic means or physical examination. For ovarian cancer, assessable disease by cancer antigen 125 (CA125) measurement is allowed.
* Willingness to sign a written consent form, and to comply with the protocol.

Exclusion Criteria:

* The following patient populations are not eligible for this study.
* Pregnant or nursing women are not eligible; women of childbearing age must agree to use an effective method of contraception. Pregnant women are not eligible because of teratogenic effects of chemotherapy.
* The presence of a second malignancy that has not received primary treatment or would complicate the primary objective of this study.
* Patients who are poor medical risk because of active, uncontrolled infection or other nonmalignant systemic disease.
* Human immunodeficiency virus (HIV) seropositive patients. Patients infected with the HIV virus will be excluded from this trial because the effect of the combination of tariquidar and docetaxel on HIV replication and/or the immune system is unknown and potentially harmful.
* Patients receiving agents which have major interactions with the cytochrome P450 3A4 (CYP3A4)drug metabolizing system and which cannot be discontinued may not be included in the trial.
* Untreated brain metastases (or local treatment of brain metastases within the last 6 months) due to the poor prognosis of these patients and difficulty ascertaining the cause of neurologic toxicities.

Outcome Measures

Primary Outcomes

Geometric Mean of Maximum Concentration of the Drug (Cmax)

In the first cycle patients were to receive docetaxel on days 1 and 8 and to be randomized to receive tariquidar on either day 1 or 8. Thus pharmacokinetic data with and without tariquidar can be compared.

Time frame: 24 hours

The Number of Participants With Adverse Events.

Here are the total number of participants with adverse events. For the detailed list of adverse events see the adverse event module.

Time frame: 4 yrs 8-11 months

Geometric Mean of Area Under Curve (AUC0)-24

Time frame: 24 hours

Clinical Response Rate

Response is determined by RECIST criteria defined as changes in only the largest diameter (unidimensional measurement) of the tumor lesion. Lesions are either measurable or non-measurable. Measurable lesions are defined as those that can be accurately measured in at least one dimension (longest diameter to be recorded) as \>/- 20 mm with conventional techniques (CT, MRI, xray) or as \>/- 10 mm with a spiral CT scan. Non-measurable lesions are defined as all other lesions (or sites of disease) including small lesions (longest diameter \<20 mm with conventional techniques or \<10 mm using spiral CT.

Time frame: 4 years, 8-11 months

Secondary Outcomes

Percent Increase in Sestamibi Area Under Curve (AUC) in Liver After Tariquidar

A significant change in the area under the curve(AUC) in liver tissue (normal tissue as a surrogate) is defined as P\<0.001. A secondary objective of this study was to establish whether tariquidar (150 mg) modulates Pgp in liver. Sestamibi is a Pgp substrate that may be a surrogate for measuring drug efflux from tumors. A baseline Tc-sestamibi scan was obtained before the administration of tariquidar. A minimum of 48 hours later, on or about day 22 a single dose of tariquidar was administered, followed by a second Tc-sestamibi scan.

Time frame: 3 - 24 hours

Percent Increase in Sestamibi Area Under Curve (AUC) in Tumor Tissue

99mTc-sestamibi is a radionuclide imaging agent used to study cardiac function that has also been shown to be a substrate for P-glycoprotein- mediated drug efflux. Because of the high expression of Pgp in liver tissue, sestamibi uptake in liver tissue is often monitored as a marker of Pgp inhibition. A significant change in the area under the curve(AUC) in liver tissue (normal tissue as a surrogate) is defined as P\<0.001.

Time frame: 3-24 hours
