  CTCAE v.5 will be used

  Up to thirty days after last dose of protocol therapy

Other Outcomes (4)

  At the end of every 21-day cycle

• Exploratory objective 2: Participant reported target tumor pain intensity assessed using the Numerical Rating Scale-11 (NRS-11)

  At the end of every 21-day cycle

Study Arms (1)

All Patients

EXPERIMENTAL

LTLD 50 mg/m2 will be administered intravenously over 30 minutes on day 1 of every 21-day cycle. MR-HIFU hyperthermia will follow infusion (+/- 30 minutes) for one hour to a target area with a target temperature of 40-45°C followed by ablation therapy (\>55°C). The HIFU hyperthermia regimen will have a duration of at least 60 minutes and will then be followed by ablation therapy. Patients may receive up to a total of 6 cycles. Subsequent treatment cycles may treat alternative target lesions. Disease status will be evaluated using standard imaging techniques (CT/MR) post each cycle.

Device: Magnetic Resonance-Guided High Intensity Focused Ultrasound; Drug: Lyso-thermosensitive Liposomal Doxorubicin

Interventions

Magnetic Resonance-Guided High Intensity Focused Ultrasound DEVICE

Magnetic resonance (MR)-guided high intensity focused ultrasound (HIFU) provides precise and controlled delivery of heat by focusing ultrasound energy inside a lesion using an external applicator without the need for a scalpel or needle. Additional therapeutic advantages of this modality include its range of bioeffects, including both high temperature tumor ablation via coagulative necrosis, and effects of lower temperature, mild hyperthermia that can help to enhance local drug delivery to tumors. Both tumor ablation and hyperthermia may be employed to potentiate the effects of chemotherapy.

Also known as: MR-HIFU

All Patients

Lyso-thermosensitive Liposomal Doxorubicin DRUG

LTLD combines doxorubicin with lyso-thermosensitive liposomes that can selectively deliver drug to tumors and when exposed to temperatures greater than 40°C, rapidly and locally releases doxorubicin in high concentrations from systemically administered LTLD. If combined with hyperthermia, doxorubicin will be released in the heated tumor margins and in any areas within the tumor that were not completely ablated and increase the likelihood of complete tumor necrosis. LTLD will extend tumor cell death to the hyperthermic regions in the peri-ablation zones and minimize the possibility of incomplete ablation or tumor recurrence.

All Patients

Eligibility Criteria

• Age: 12 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• 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.

You may not qualify if:

• 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.
