Evaluation of the Safety, Effectiveness & Usability of the XACT Robotic System for Image Guided Percutaneous Procedures

Not Applicable

Completed

• Conditions: CT-guided Minimally Invasive Procedures e.g., Biopsies
• Interventions: Device: XACT Robotic System

• Registration Number: NCT03008603
• Lead Sponsor: Xact Robotics Ltd.

Brief Summary

This is a prospective, single-arm study is to evaluate the safety, effectiveness and usability of the XACT device. Subjects undergoing CT-guided, minimally invasive percutaneous procedures in the interventional radiology suite, e.g., core biopsy, will participate in the summary. Clinical accuracy will be the primary efficacy endpoint. Usability and safety will also be evaluated.

Detailed Description

This is a prospective, single-arm study is to evaluate the safety, effectiveness and usability of the XACT device. The study will be approved by the Institutional Review Board (IRB) at each of the participating centers prior to patient enrollment.

Subjects undergoing CT-guided, minimally invasive percutaneous procedures in the interventional radiology suite, e.g., core biopsy, fine needle aspiration (FNA), tumor ablation, etc., and willing to sign an informed consent document will be screened for compliance with the study inclusion and exclusion criteria.

A total of thirty (85) subjects will be enrolled in the study at 5 medical centers. The intention is to recruit subjects, which will cover a variety of CT-guided interventional procedures and a variety of different procedural tools that may be used with the device. Investigators will screen patients based on the inclusion/exclusion criteria described below and the subjects' demographic, general medical history, medical condition/indication, coagulation factors, concomitant medications and vital signs will be obtained.

Clinical accuracy will be the primary efficacy endpoint and is defined as the ability to place the instrument or procedural tool at a location suitable for the planned intervention. The investigator will review the final instrument position on the post-placement CT images to determine if the pre-operative planned target was reached. This information will be used to calculate success rate.

Additionally, the usability of the XACT device will be evaluated using a rating scale by assessing the ease of device setup, device operation, pre-operative planning, robot positioning, guiding and needle advancement. The total time of the procedure will be recorded, as will the number of CT scans performed and the radiation dose (DLP and CTDI). The distance from the tip of the needle/tool to the target, once the XACT robot reaches the pre-defined target will be measured in order to determine system accuracy in quantitative terms using the system tools.

Primary Outcome Measures

Name	Time	Method
The primary endpoint of the study is to evaluate the clinical accuracy of the XACT system.	End of procedure	Clinical accuracy of the study will be determined by the ability of the XACT system to reach the pre-defined target in each procedure.

Secondary Outcome Measures

Name	Time	Method
The secondary endpoint of the study is to evaluate the usability of the XACT system under actual use clinical conditions.	End of procedure	usability of the XACT device will be evaluated using a rating scale by assessing the ease of device setup, device operation, pre-operative planning, robot positioning, guiding and needle advancement.
