Actual (reported)Primary objective 1: Response of treated target lesion(s) assessed by CT or MRI
The Response Evaluation Criteria in Solid Tumors (RECIST v1.1) will be used
At the end of every 21-day cycle
Primary objective 2: The number of participants with treatment-related adverse events as assessed by the Common Terminology Criteria of Adverse Events (CTCAE) v.5
CTCAE v.5 will be used
Up to thirty days after last dose of protocol therapy
Exploratory objective 1: Response of non-target lesion(s) assessed by CT or MRI
At the end of every 21-day cycle
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.
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.

At the end of every 21-day cycle
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.
