Delphinus SoftVue Prospective Case Collection - ARM 2 (SV PCC ARM2)
|ClinicalTrials.gov Identifier: NCT02977247|
Recruitment Status : Enrolling by invitation
First Posted : November 30, 2016
Last Update Posted : February 9, 2018
The SoftVue™ is a whole breast ultrasound system with an automated scanning curvilinear ring‐array transducer that employs UST. It is currently cleared under FDA 510(k) K123209 and K142517 for use as both a B‐mode ultrasonic breast imaging system and color imaging of transmission data (sound speed and attenuation). SoftVue™ is not intended to be used as a replacement for screening mammography.
SoftVue uses non‐ionizing ultrasound energy to generate tomographic image volumes of the whole breast. While the patient lays prone on a padded table with one breast comfortably submerged in a bath of warm water, a ring‐shaped transducer, 22 cm in diameter, encircles the breast and pulses low‐frequency sound waves through the water and into the breast tissue. More than 2000 elements in the curvilinear transducer's 360 degree array emit and receive ultrasound signals to analyze echoes from the breast anatomy in all directions, from the chest wall to the nipple. Not only does SoftVue capture data from the reflection of the sound waves off of tissue boundaries and structures within the breast, but because the transducer surrounds the whole breast, SoftVue also captures signals that are transmitted through the breast. This additional transmission data enhances the visualization of the anatomic structure of the breast tissue and is not currently available in any other commercially marketed breast ultrasound device.
This prospective, multicenter, multi‐arm, clinical case collection program is IRB‐approved and will be conducted in compliance with Good Clinical Practice, the Declaration of Helsinki and all applicable regulatory requirements. Arm 2 aims to collectively enroll up to 1,000 women at a total of up to 8 clinical sites. The design of Arm 2 in this protocol is strictly limited to case collection and is non-interventional; any investigational and/or statistical plans for future analyses will be prepared and registered separately, if they are applicable to the requirements of FDAAA 801.
Arm 2 is limited to the cohort of diagnostic female patients of any breast density composition category, who have been recommended for a breast biopsy (BI-RADS 4 or 5) after diagnostic imaging, or who have confirmed imaging findings. Matched sets of diagnostic imaging and SV exams, from the same patient, demographic information, and clinical outcome data, will be collected during diagnostic workup. Ultrasound characteristics for all types of lesions, whether they are benign or malignant, will be collected as well as objective and subjective breast density composition data. Ultrasound image data may be acquired with modified SoftVue devices, which have passed safety and quality evaluations per Delphinus' quality management system (QMS) and satisfy design change control standards, at select clinical sites in accordance with 21 CFR 812.2 (b), as a routine part of feasibility, validation, and verification testing for engineering and product development purposes.
The exams and clinical data accumulated in this prospective case collection (PCC) protocol will populate a database from which future investigations may be designed for peer reviewed publication, development of user training curricula, building teaching case, and creating new marketing materials for SoftVue.
