About this study

Official title: Phase 2, Randomized Study of the Tolerability and Safety of the OsciPulse Device for the Prevention of VTE

This is a Phase 2 safety and tolerability trial that will take place in two parts. Part one of the trial will determine the tolerability of the OsciPulse device on healthy subjects who wear the device for up to three hours. Healthy volunteers will answer questionnaires and may undergo an ultrasound test at the end of their participation in the trial.

Part two of the trial will determine the safety and tolerability of the OsciPulse device on subjects admitted to Penn Presbyterian Medical Center. Eligible subjects will be enrolled for 6 hours. In the first 3 hours, subjects will wear the standard of care intermittent pneumatic compression device or the OsciPulse device. In the second 3 hours, the subject's device will be switched and subjects will wear the alternate device not used in the first 3 hours. Subjects will answer questionnaires and may undergo an ultrasound at the end of the first 3 hours and at the end of the second 3 hours (at hour 6).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part 1 - Subject's Response to Tolerability Questionnaire

    Tolerability will be measured by subject's response to questionnaires to assess their experience with the device. This will be measured on a linear 100 mm visual acuity scale measured in millimeters. Subjects are provided with the scale and asked to make a mark on the line that corresponds to their experience with the device. The least favorable rating is on the left hand side, the most favorable rating is on the right hand side of the scale. The mark on the line is measured in millimeters, resulting in least favorable scores having a lower score, and most favorable ratings having a higher score.

    Measured: up to 3 hours

  2. Part 1 - Safety Assessment Through Collection of Adverse Events

    Safety will be assessed by collecting \& reviewing all adverse events while subject is wearing the device.

    Subjects will indicate if the device caused 1) no discomfort, 2) mild discomfort, or 3) significant discomfort. To move on to Part 2, all subjects in Part 1 must indicate that there was not "significant discomfort."

    Measured: up to 3 hours

  3. Part 2 - Subject's Response to Tolerability Questionnaire

    Tolerability will be measured by subject's response to questionnaires to assess their experience with the device. This will be measured on a linear 100mm visual acuity scale measured in millimeters. Subjects are provided with the scale and asked to make a mark on the line that corresponds to their experience with the device. The minimum (least favorable) rating is on the left hand side and is equal to zero (0), the maximum (most favorable) rating is on the right hand side of the scale and is equal to one hundred (100). For Comfort, scores range from "very disruptive" (0) to "no effect" (10). For Disruption, scores range from "very disruptive" (0) to "no effect" (10). For Noise, scores range from "very loud" (0) to "not noticeable" (10). For Movement, scores range from "very restrictive" (0) to "no effect" (10). The mark on the line is measured in millimeters, resulting in minimum (least favorable) scores having a lower score, and maximum (most favorable) ratings having a higher score.

    Measured: 6 hours

  4. Part 2 - Safety Assessment Through Collection of Adverse Events.

    Safety will be assessed by collecting all adverse events while the subject is wearing the device.

    Measured: 6 hours

Questions about this trial

What is this clinical trial studying?

A study testing OsciPulse in people with Venous Thromboembolism and Deep Vein Thrombosis, run by University of Pennsylvania at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1 - Subject's Response to Tolerability Questionnaire (time frame: up to 3 hours). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Nov 2023.
