A Pilot Study of Thermodox and MR-HIFU for Treatment of Relapsed Solid Tumors

Inclusion Criteria: * AGE: ≥ 12 years of age. * DIAGNOSIS: Histologically confirmed malignant solid tumors * TUMOR LOCATION: Patient must have at least one tumor located in areas accessible to HIFU, which will be defined as the target lesion(s). Target lesions must be reachable within the normal safety margins of HIFU as specified in the instructions for use. * TARGET LESION(S): Radiographically measurable/evaluable solid tumor target lesion(s). * THERAPEUTIC OPTIONS: \- Malignant Tumor: 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. * PRIOR THERAPY: * Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering on this study. * No limitation on the number of prior chemotherapy regimens that the patient may have received prior to study entry. * Myelosuppressive chemotherapy: The last dose of all myelosuppressive anticancer drugs must be at least 3 weeks prior to study entry (6 weeks for prior nitrosoureas) Prior treatment with anthracyclines is allowed as long as total cumulative dose is ≤ 450 mg/m2. * Immunotherapy: The last dose of immunotherapy (monoclonal antibody or vaccine) must be at least 3 weeks prior to study entry. * Biologic (anti-cancer agent): The last dose of all biologic agents for the treatment of the patient's cancer (such as retinoids or tyrosine kinase inhibitors) must be at least 7 days prior to study entry. * Radiation therapy: The last dose of radiation to more than 25% of marrow containing bones (pelvis, spine, skull) must be at least 4 weeks prior to study entry. The last dose of all other local palliative (limited port) radiation must be at least 2 weeks prior to study entry. * Stem Cell Transplantation. At least 42 days post-autologous stem cell transplant or at least 90 post-allogeneic transplant and recovered from toxicities without evidence of graft versus host disease and on stable doses of immunosuppressive medications if required. * Growth Factors. The last dose of colony stimulating factors, such as filgrastim, sargramostim, and erythropoietin, must be at least 1 week prior to study entry, the last dose of long-acting colony stimulating factors, such as pegfilgrastim, must be at least 2 weeks prior to study entry. * CONCURRENT THERAPIES: \- No other anti-cancer therapy (chemotherapy, biological therapy, radiation therapy) is permitted. * PERFORMANCE STATUS: * Lansky/Karnofsky performance level ≥ 50% (See Appendix I). * Patients who are unable to walk because of paralysis or motor weakness, but who are up in a wheelchair will be considered ambulatory for the purpose of calculating the performance score. * HEMATOLOGIC FUNCTION: * Peripheral absolute neutrophil count (ANC) of ≥ 1000/µL. * Platelet count ≥ 75,000/µL (transfusion independent (no transfusion within at least 7 days prior to enrollment)). * HEPATIC FUNCTION: * Total bilirubin must be ≤ 1.5 times the upper limit of normal (ULN) for age and gender. * SGPT (ALT) must be ≤ 3.0 times the upper limit of normal for age. * RENAL FUNCTION: Serum creatinine ≤ ULN for age/sex OR a creatinine clearance ≥60 mL/min/1.73 m2. * CARDIAC FUNCTION: Adequate Cardiac Function with Ejection Fraction \> 50% by echocardiogram. Exclusion Criteria: * Clinically significant unrelated systemic illness, such as serious infections, hepatic, renal or other organ dysfunction, which in the judgment of the Principal or Associate Investigator would compromise the patient's ability to tolerate study interventions. * Patients who are pregnant or breast-feeding are not eligible for this study due to risks of fetal and teratogenic adverse events seen in animal/human studies with doxorubicin. Negative pregnancy tests must be obtained in girls who are post-menarchal. Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method beginning at the signing of informed consent and until at least 30 days after the last dose of study drug. The definition of adequate contraception will be based on the judgment of the principal investigator or designated associate. * Implant or prosthesis within the path of the HIFU beam. * Target pathway \<1 cm from nerve plexus, spinal canal, or bowel. * Target lesion in the skull. * Inability to undergo MRI and/or contraindication for MRI. * Inability to tolerate stationary position during HIFU. * Previous history of hypersensitivity to doxorubicin or its liposomal formulations. * Patients currently receiving other anticancer agents. * Patients currently receiving other investigational agents.
