The HistoSonics System for Treatment of Primary and Metastatic Liver Tumors Using Histotripsy (#HOPE4LIVER US)

This trial is a single arm, non-randomized prospective trial. The objective of this trial is to evaluate the efficacy and safety of the HistoSonics System for the treatment of primary or metastatic tumors located in the liver.

This trial is a single arm, non-randomized prospective trial. Following histotripsy treatment of liver tumor(s), subjects will undergo imaging ≤36 hours post-index procedure to determine technical success. Subjects will then be followed for 30 days. Data through the 30-day time point will be used for a Regulatory Submission to the FDA. Additionally, subjects will be followed for five (5) years post-index procedure, with evaluations at the 6-month and annual time points to estimate the efficacy and safety profile of the HistoSonics System.

             - Renal function: serum creatinine <2x ULN, and

             - Hematologic function: neutrophil count >1.0 x 10^9/L and platelet >50 x 10^9/L

         8. Subject has an International Normalized Ratio (INR) score of <2.0 , ≤7 days prior to the index procedure

         9. Subject has not responded to and/or has relapsed and/or is intolerant of other available therapies including locoregional therapies, chemotherapy, immunotherapy and targeted therapies

         10. The tumor(s) selected for histotripsy treatment must be ≤3 cm in longest diameter

         11. Subject has an adequate acoustic window to visualize targeted tumor(s) using ultrasound imaging

         12. Subject has a maximum of three (3) tumors to be treated with histotripsy during the index procedure, regardless of how many tumors the subject has.

         3. In the Investigator's opinion, the subject has co-morbid disease(s) or condition(s) that would cause undue risk and preclude safe use of the HistoSonics System

         4. Subject has a serum creatinine >2.0 mg/dL or estimated glomerular filtration rate (EGFR) <30, unless on dialysis

         5. Subject has major surgical procedure or significant traumatic injury ≤2 weeks prior to the planned index procedure or not fully recovered (CTCAE grade 1 or better) from side effects/complications of such procedure or trauma

         6. Subject has not recovered to common terminology criteria for adverse events (CTCAE) grade 1 or better from any adverse effects (except alopecia, fatigue, nausea, vomiting and peripheral neuropathy) related to previous anti-cancer therapy

         7. Subject has a history of, or suspected to have, bleeding disorders that are uncorrectable

         8. Subject has coagulopathy that is uncorrectable

         9. Subject has a planned cancer treatment (e.g. resection, chemotherapy, etc.) after the planned index-procedure date and prior to completion of the 30-day follow-up visit

         10. Subject has previous treatment with bevacizumab that has not been discontinued >40 days prior to the planned index-procedure date

         11. Subject has planned bevacizumab treatment prior to completion of the 30-day follow-up visit

         12. Subject has previous treatments with chemotherapy and/or radiotherapy that has not been discontinued ≥2 weeks prior to the planned index-procedure date and has not recovered (CTCAE grade 1 or better) from related toxicity (except alopecia and peripheral neuropathy)

         14. Subject has a life expectancy less than six (<6) months

         15. In the opinion of the Investigator, histotripsy is not a treatment option for the subject

         16. Subject has a concurrent condition that, in the investigator's opinion, could jeopardize the safety of the subject or compliance with the protocol

         17. Subjects' tumor(s) is not treatable by the System's working ranges (refer to User Manual)

         18. Subject has a known sensitivity to contrast media and cannot be adequately pre-medicated

         19. Subjects' target tumor(s) has/have had prior locoregional therapy (e.g. ablation, embolization, radiation)

         20. Subject is eligible for surgical resection

         21. Targeted tumor(s) treatment volume overlaps a non-targeted tumor visible via imaging

         22. The targeted tumor(s) is not clearly visible with diagnostic ultrasound and computed tomography (CT) or magnetic resonance (MR) imaging

         23. The targeted tumor(s) is located in liver segment 1
