General information about the trial
|
|||
Main objective of the trial |
To determine the safety and feasibility of detecting acoustic signals related to blood supply in subjects with acute stroke by using the SONAS® device.
|
||
Protection of trial subjects |
The clinical investigation was conducted in compliance with the Declaration of Helsinki, clinical investigation plan, EN ISO 14155:2011, ICH GCP, and any conditions of approval imposed by the reviewing ethics committee, competent authority and/or local institution.
Only subjects with acute stroke meeting all inclusion criteria and none of the exclusion criteria had to be entered in the clinical investigation. All subjects were free to withdraw at any time and for any reasons.
Subjects underwent SONAS® testing only after receiving routine clinical care for stroke management (including cerebral imaging computed tomography [cCT] or cerebral magnetic resonance imaging [cMRI]). All subjects were carefully monitored for the occurrence of adverse events (AEs) from the start of any investigation-related procedure until 72 hours after the second SONAS® testing.

Recruitment
|
|||||||||||||
Recruitment details |
Male and female subjects aged at least 18 years with acute stroke diagnosed within 24 hours of symptoms onset and assessed intracranial arteria circulation by cMRI or cCCT were recruited in 1 center in Germany. The first subject signed the informed consent form on 01-Apr-2019 and the last subject on 25-Dec-2019. | ||||||||||||
Pre-assignment
|
|||||||||||||
Screening details |
20 subjects signed the informed consent. The SONAS® test was performed at least once on all subjects using the SONAS® device. | ||||||||||||

Diagnostic performance results of SONAS® at first assessment [1] | ||||||||||||||
End point description |
The endpoint consists of the following parameters:
• Diagnostic accuracy: percentage of subjects in whom the SONAS® assessment result matched the reference standard assessment
• Sensitivity: percentage of subjects positive per SONAS®, among those subjects with confirmed strokes per the reference standard
• Specificity: percentage of subjects negative per SONAS®, among those subjects confirmed as not having a stroke per the reference standard

Date |
Amendment |

10 Jul 2019 |
Changes to version 3.0 (26-Nov-2018):
- All components and subcomponents of the SONAS® system according to the investigator’s brochure were described.
- Software version 1.12 was to be used for the SONAS® operating unit.
- Inclusion criterion no. 3 was adapted. The required NIHSS score was reduced from ≥10 to ≥6, because neurological deficits may develop in a delayed manner, i.e. symptoms may be mild at admission despite a later proven vascular occlusion.
- The targeted study population was extended from “subjects with acute large vessel occlusion stroke” to “subjects with acute stroke”, because in some subjects with severe neurological deficits, vascular occlusion cannot be proven anymore at admission (e.g. due to spontaneous recanalization). The requirement for a confirmed occlusion was removed in inclusion criterion no. 5.
- If an MRI or CT is performed as part of the routine clinical practice at 24 hours, images were to be collected.
- It was clarified that one SONAS® application may include a repeat test immediately after the first test to improve the data analysis if it does not jeopardize the subject's health according to the investigator’s judgement.
- If the subject was able to give consent but was unable to sign the consent form in person due to a physical disability, the subject's willingness to participate in the study may be confirmed by a witness. |
