Brief Summary

This study will evaluate the tolerance and effects of tariquidar, given in combination with one of three anticancer drugs, for treating solid tumors. Tariquidar works by blocking a pump on a cancer cell. The pump on a cell that prevents anticancer drugs from accumulating is called Pgp (P-glycoprotein). Researchers hope to see whether cancer-fighting drugs can stay in the cells longer. Patients ages 2 to 18 who have solid tumors may be eligible for this study. Tariquidar is infused intravenously (IV) over 30 minutes, given every 21 to 28 days, with one drug that kills cancer cells. Patients are examined by a doctor at least once weekly during treatment and will have routine blood tests twice weekly. They will receive one of the following drugs with tariquidar: doxorubicin (Adriamycin ), vinorelbine (Navelbine ), or docetaxel (Taxotere ). At the first treatment cycle only, there is a baseline Sestamibi scan before treatment and a second one immediately after drug administration. If patients receive tariquidar with doxorubicin, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, followed by doxorubicin by IV over 15 minutes. Dexrazoxane, which decreases damaging effects of doxorubicin on the heart, is also given by IV over 15 minutes. Granulocyte colony stimulating factor (G-CSF) is injected daily 48 hours after doxorubicin, to alleviate doxorubicin s effect on white blood cells. If patients receive tariquidar with vinorelbine, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, immediately followed by vinorelbine by IV over 10 minutes; then 1 week later, tariquidar is again given, immediately followed by vinorelbine by IV for 10 minutes. G-CSF is given daily. If patients receive tariquidar with docetaxel, tariquidar is given alone. Then 48 to 72 hours later, the second dose is given, followed by docetaxel by IV over 60 minutes. Drugs to prevent allergic reactions are given before and after each docetaxel dose. G-CSF is given daily. Tariquidar may affect blood pressure during infusion, and there can be reduction of normal blood cells, gastrointestinal problems, and allergic reactions. The radioactive Sestamibi can cause headache, chest pain, and nausea. Radiation used in this study has been approved as involving a slightly greater than minimal risk for adults and an acceptable risk for children. This radiation is considered necessary to obtain information desired. One possible effect is a slight increase in the risk of cancer. This study may or may not have a direct benefit for participants. However, knowledge gained may benefit people with cancer in the future.

Eligibility Criteria

Age2 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Age: Patients must be greater than or equal to 2 and less than or equal to 18 years of age.
  • Diagnosis: Histologically confirmed solid tumors which may include but are not limited to rhabdomyosarcoma and other soft tissue sarcomas, Ewing's sarcoma family of tumors, osteosarcoma, neuroblastoma, Wilms' tumor, hepatic tumors, germ cell tumors, and primary brain tumors. In patients with brain stem or optic gliomas the requirement for histological confirmation may be waived.
  • Measurable/Evaluable Disease: Patients must have measurable or evaluable tumors.
  • Prior Therapy: The patient's cancer must have relapsed after or failed to respond to frontline curative therapy and there must not be other potentially curative treatment options available. Curative therapy may include surgery, radiation therapy, chemotherapy, or any combination of these modalities.
  • For patients receiving doxorubicin on this study, the patient must have had their last dose of radiation therapy at least four weeks prior to study entry; For patients receiving docetaxel or vinorelbine, the patient must have had their last dose of extensive radiation (craneospinal or more than 50 percent of pelvis) at least 4 weeks prior to study entry or last dose of limited field radiation (local) at least 2 weeks prior to study entry.
  • Patients must have had their last dose of chemotherapy at least 21 days prior to study entry (28 days for nitrosoureas), and their last dose of any investigational cancer therapy at least 30 days prior to study entry.
  • Patients must have recovered from the toxic effects of all prior therapy before entry onto this trial.
  • Patients with brain tumors must be on a stable or tapering dose of corticosteriods for 7 days prior to the baseline scan performed for the purpose of assessing response to therapy on this study.
  • Patients should be off colony stimulating factors such as G-CSF, GM-CSF, erythropoietin, and IL-11 for at least 72 hours prior to study entry.
  • Lifetime cumulative dose of anthracycline: Restrictions on the prior cumulative dose anthracylines only apply to patients who will receive doxorubicin in combination with tariquidar.
  • The lifetime cumulative dose of anthracycline must be less than or equal to 300 mg/m(2) in patients who will receive doxorubicin in combination with tariquidar, if the anthracycline was administered as a bolus injection without a cardioprotectant (e.g., dexrazoxane) OR if the patient had mediastinal radiation.
  • The lifetime cumulative dose of anthracycline must be less than or equal to 400 mg/m(2), if the anthracycline was administered by continuous infusion or with a cardioprotectant and the patient has not had mediastinal radiation.
  • Performance Status: Patients should have an ECOG performance status of 0,1, or 2. Patients who unable to walk because of paralysis or weakness, but who are up in a wheelchair will be considered ambulatory for the purpose of calculating the performance score.
  • Hematologic Function: Patients must have adequate bone marrow function, defined as a peripheral absolute granulocyte count of greater than or equal to 1,500/microL, hemoglobin greater than or equal to 8 gm/dL, and a platelet count greater than or equal to 100,000/microL.
  • Hepatic Function: Patients must have adequate liver function, defined as bilirubin within normal limits, SGPT (ALT) less than 2x the upper limit of normal.
  • +4 more criteria

You may not qualify if:

  • Clinically significant unrelated systemic illness, such as serious infections, hepatic, renal or other organ dysfunction, which in the judgement of the Principle or Associate Investigator would compromise the patient's ability to tolerate and of the agents in this trial or are likely to interfere with the study procedures or results.
  • Patients with a history of bone marrow transplantation within the previous 4 months or extensive radiotherapy (craniospinal radiation, total body radiation, or radiation to more than half of the pelvis) within the previous 4 months.
  • Pregnant or breast feeding females are excluded because tariquidar in combination with a cytotoxic drug may be harmful to the developing fetus or nursing child.
