Intervento / Trattamento |
|---|---|
|
Sperimentale: First in Human (FIH)
Initial phase of the trial.
Includes a broad spectrum of population groups (e.g. de novo, concurrent with URS, residual fragments) to demonstrate feasibility.
Intervention consists of the non-invasive application of ultrasound to move stones within the kidney and ureter.
Procedure conducted with the Propulse 1 device and C5-2 transducer.
Subjects (n = 15) receive up to 40 push bursts.

Move kidney stones with Propulse 1 device.
|
|
Sperimentale: De Novo Small Stone
Segment of the trial focused specifically on subjects with small (≤ 5 mm) stones under observation management.
Intervention consists of the non-invasive application of ultrasound to move stones within the kidney and ureter with the goal to facilitate passage.
Procedure is conducted with the Propulse 1 device and SC-X transducer.
Subjects (n = 2) receive multiple Push bursts up to a maximum cumulative dose exposure of 5 minutes.
Each burst is a maximum of 3 seconds in duration and 200 W/cm2 in intensity.

Sperimentale: Concurrent with URS
Segment of the trial focused specifically on subjects undergoing ultrasonic propulsion concurrently with their ureteroscopy guided laser lithotripsy procedure.
Study provides visual observation of stone motion and any potential tissue injury.
Intervention consists of the non-invasive application of ultrasound to move stones within the kidney and ureter.
Procedure is conducted with the Propulse 1 device and SC-X transducer.
Subjects (n = 18) receive multiple Push bursts up to a maximum cumulative dose exposure of 5 minutes.
Each burst is a maximum of 3 seconds in duration and 200 W/cm2 in intensity.

Sperimentale: Obstructing Stone - Pushing only
Segment of the trial focused specifically on subjects reporting to clinic or the emergency department with an obstructing stone.
Intervention consists of the non-invasive application of ultrasound to relieve pain and facilitate passage.
Procedure is conducted with the Propulse 1 device and SC-X transducer.
Subjects (n = 16) receive multiple Push bursts up to a maximum cumulative dose exposure of 5 minutes.
Each burst is a maximum of 3 seconds in duration and 200 W/cm2 in intensity.
|
Move kidney stones with Propulse 1 device.
|
|
Sperimentale: Residual Fragment (Treatment group)
Segment of the trial focused specifically on subjects with small (≤ 5 mm) residual fragments following lithotripsy.
This is the Treatment arm of a randomized control trial.
Intervention consists of the non-invasive application of ultrasound to move stones within the kidney and ureter with the goal to facilitate passage.
Procedure is conducted with the Propulse 1 device and SC-X transducer.
Subjects (n = 54) receive multiple Push bursts up to a maximum cumulative dose exposure of 5 minutes.
Each burst is a maximum of 3 seconds in duration and 200 W/cm2 in intensity.
|
Move kidney stones with Propulse 1 device.
|
|
Nessun intervento: Residual Fragment (Control group)
Segment of the trial focused specifically on subjects with small (≤ 5 mm) residual fragments following lithotripsy.
This is the Control arm of a randomized control trial.
Subjects (n = 54) follow same protocol as Residual Fragment (Treatment group) but do not receive the ultrasonic propulsion intervention.
|
|
|
Sperimentale: Obstructing Stone - Pushing + Dislodging
Segment of the trial focused specifically on subjects reporting to clinic or the emergency department with an obstructing stone.
Participants were separate from the Obstructing Stone - Pushing only based on a stone skin-to-stone distance < 8 mm.
Intervention consists of the non-invasive application of ultrasound to relieve pain and facilitate passage.
Procedure is conducted with the Propulse 1 device and SC-X transducer.
Subjects (n = 13) receive both Dislodging and Push bursts up to a maximum cumulative dose exposure of 5 minutes.
This is the only population to receive the Dislodging bursts, which consist of higher amplitude (up to 7 MPa) and shorter duration pulses compared to pushing.
The Push burst is a maximum of 3 seconds in duration and 200 W/cm2 in intensity.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Measurement of Stone Motion Caused by Ultrasound
Lasso di tempo: At the time of the procedure. To be evaluated with each therapy pulse over an approximately 1-hour study. Confirmed with post-procedure review of the study video.
|
Percentage of study participants for which stone motion was observed on the real-time ultrasound images.
|
At the time of the procedure. To be evaluated with each therapy pulse over an approximately 1-hour study. Confirmed with post-procedure review of the study video.
|
|
Measurement of Stone Passage
Lasso di tempo: Measurement occurs over 3 weeks (weekly phone call or email encounter with the subject) plus review of the subject's medical chart up to the point the subject is exited from the study.
|
The percentage of participants reporting visual observation of stone passage or confirmed with follow-up imaging.
For the residual fragment RCT population specifically, the percentage of participants reporting visual observation of stone passage during the 3-week follow-up period after the procedure or randomization (Control group).
|
Measurement occurs over 3 weeks (weekly phone call or email encounter with the subject) plus review of the subject's medical chart up to the point the subject is exited from the study.

Measurement of Relapse
Lasso di tempo: Measurement up to 5 years post-procedure. This includes a phone call or email exchange semi-annually for up to 3-years and a medical record review (including imaging) semi-annually for up to 5-years.
|
The percentage of participants experiencing stone relapse defined as: an unscheduled, symptomatic visit for stones on the study side, surgery for stones on the study side, or stone growth of a residual fragment measured by clinical imaging exams.
This measurement is specific to the residual fragment population and associated randomized control trial.
Only a single relapse event is counted per participant, though a participant could experience more than one event.

Lo studio misura il tasso a livello di soggetto di eventi avversi con insorgenza dopo la procedura (gruppo di trattamento) o randomizzazione (gruppo di controllo) attraverso il follow-up di 3 settimane, determinato da un revisore in cieco come potenzialmente correlato al dispositivo, alla procedura o la malattia renale di base del soggetto.
(Endpoint secondario per entrambi i SAP).

Number of Participants With Discomfort Related to the Device or Procedure
Lasso di tempo: At the time of the procedure. To be evaluated over an approximately 1 hour study.
|
Pre-Procedure: The participant will be asked directly what discomfort, on a scale of 0 (no pain) to 10 (worst pain possible), they are experiencing and to point to where the discomfort/pain is located. This is the participant's recorded baseline measure. During Procedure: The participant will be asked directly if they are experiencing any new or different discomfort, on a scale of 0 (no pain) to 10 (worst pain possible), and to point to where the discomfort/pain is located. Any new or different discomfort above baseline will be assumed related to the device or procedure; there is no minimum threshold for reporting. Post Procedure: The participant will be asked directly what discomfort, on a scale of 0 (no pain) to 10 (worst pain possible), they are experiencing and to point to where the discomfort/pain is located. Any new or different discomfort above baseline will be assumed related to the device or procedure; there is no minimum threshold for reporting. |
