The HistoSonics System for Treatment of Primary and Metastatic Liver Tumors Using Histotripsy

Not Applicable

Active, not recruiting

• Conditions: Hepatocellular Carcinoma; Liver Metastases; Liver Neoplasms
• Interventions: Device: HistoSonics System

• Registration Number: NCT04572633
• Lead Sponsor: HistoSonics, Inc.

Brief Summary

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. The co-primary safety and efficacy endpoints must be met for the trial to be successful.

Detailed Description

This trial is a single arm, non-randomized, multicenter, 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. Additionally, subjects will be evaluated at 6 months and followed annually for up to five (5) years post-index procedure.

The #HOPE4LIVER US trial required pooling data from #HOPE4LIVER US and #HOPE4LIVER EU/UK (NCT04573881). Subjects were treated with the same intervention (HistoSonics System) using identical protocols tailored to the regulatory requirements for each geography.

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.

Exclusion Criteria

1. Subject is pregnant or planning to become pregnant or nursing (lactating) during the trial period
2. Subject is enrolled in another investigational trial and/or is taking investigational medication and/or has been treated with an investigational device ≤30-days prior to planned index procedure date
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)

Primary Outcome Measures

Name	Time	Method
Primary Efficacy: Technical Success	≤36 hours post-index procedure	Technical success, defined as the treatment volume/treatment dimensions being greater than or equal to the targeted tumor, and with complete tumor coverage, via computed tomography (CT) or magnetic resonance (MR) imaging. \[Core Laboratory Adjudicated\] Primary efficacy was assessed per tumor with a performance goal of greater than 70%.; Primary efficacy was assessed after the first forty (40) consecutive evaluable subjects were enrolled. Evaluable subjects had sufficient CT or MR imaging data to allow the independent core laboratory to evaluate technical success.
Primary Safety: Procedure-Related Major Complications	30 days post-index procedure	Number of index procedure related major complications, including device-related events defined as Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher toxicities observed up to 30-days post index-procedure. \[Clinical Events Committee Adjudicated\] Primary safety was assessed per participant with a performance goal of less than 25%.; Primary safety was assessed on all subjects enrolled, after the first forty (40) consecutive subjects evaluable for technical success were enrolled. Evaluable subjects had sufficient CT or MR imaging data to allow the independent core laboratory to evaluate technical success. Enrollment of 44 total subjects was required to assess forty (40) subjects evaluable for technical success.

Procedure-Related Major Complications	30 days post-index procedure	Number of index procedure related major complications, including device-related events defined as Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or higher toxicities observed up to 30-days post index-procedure. \[Clinical Events Committee Adjudicated\]
Secondary Efficacy: Technique Efficacy	30 days post-index procedure	Technique efficacy, defined as the lack of a nodular or mass-like area of enhancement within or along the edge of the treatment volume assessed via CT or MR imaging at 30-days post-procedure. \[Core Laboratory Adjudicated\]
