Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multicentre, randomised geko™ venous thromboembolism (VTE) prevention study will prospectively collect clinical data on VTE occurrences in immobile patients after stroke, who will be randomised, on a 1:1 allocation, to receive either standard of care (Intermittent Pneumatic Compression) or geko™ neuromuscular electrostimulation device. The aim is to assess the prevention of VTE during a follow-up period of 90 days (three months) post-randomisation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Venous thromboembolism (VTE) is a disabling and potentially fatal outcome that may be acquired after having a stroke. The standard treatment to prevent the development of VTE is to give anticoagulation medication. However, this is not recommended in the UK after stroke. Instead the recommended treatment is Intermittent Pneumatic Compression (IPC), where cuffs placed around the lower legs are filled with air to help squeeze the legs and induce blood flow. However, not all patients are able to receive or tolerate IPC treatment. Another treatment which has shown promising results to prevent VTE in immobile patients after stroke, is with a medical device called the geko™ device. The geko™ device is a CE marked medical device which means the manufacturer has checked that the device complies with the essential safety and performance requirements for its' intended use which is to increase blood circulation to help prevent VTE. The aim of this study is to determine if the geko™ device is more effective at preventing VTE in immobile acute stroke patients, than the current IPC standard of care treatment. Following the consent process, stroke patients will be randomised to receive either IPC or geko device. Both devices will be applied until the patient can walk again without help, or for a maximum of 30 days. A compression Doppler exam of the legs will be conducted after 7 days or at discharge if the patient recovers earlier (optional) and after 14 days (mandatory). At 14 days post-randomisation, a patient questionnaire about the comfort of the device, as well as additional health information will be collected. At 30 days after randomisation, additional information about symptomatic DVTs or PEs etc., will be collected from the participant's medical notes. A final follow-up will then be conducted over the phone after 90 days to find out about the patient's recovery, health, mobility and quality of life.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Standard block randomisation
Primary Study Purpose

PREVENTION

Blinding Strategy

SINGLE

Outcome Assessors
The trial will be single blind for the primary outcome. Devices will be taken off before participants have Doppler imaging at 7 days and 14 days. Data on VTE will be taken by a blinded researcher using information available on hospital information systems.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

geko™ T-3 interventional

The geko™ device will be applied bilaterally as soon as possible after randomisation and each geko™ device will be used to deliver one 24-hour dose. Devices will be worn continuously and changed every 24 hours. Treatment will be continued for a maximum of 30 days or until patient recovers mobility, or is discharged into the community, or meet other defined criteria, whichever comes earlier.

Group Type EXPERIMENTAL

geko™ device

Intervention Type DEVICE

Neuromuscular electrical stimulation of the peroneal nerve

Intermittent Pneumatic Compression (IPC)

Control treatment will be IPC using NHS approved devices as used for standard clinical care. They will be applied to both legs as soon as possible after randomisation. They will not be changed unless damaged or soiled. Treatment will be continued for a maximum of 30 days or until patient recovers mobility, or is discharged into the community, or meet other defined criteria, whichever comes earlier.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Age 18 years or older
2. Clinical diagnosis of acute stroke (WHO criteria)
3. Within 36 hours of symptom onset
4. Not able to get up from a chair/out of bed and walk to the toilet without the help of another person

Exclusion Criteria

1. Inability to gain consent from the patient, or a declaration from a Personal Consultee or Nominated Consultee
2. Unwitnessed onset with a long lie on the floor before admission
3. Clinically apparent deep vein thrombosis at screening
4. Patient is expected to require palliative care within 14 days
5. Patient does not live in the local catchment area and is expected to be transferred to their local hospital for on-going care.
6. Patient has recently been involved in or is currently involved in a clinical trial for either a medical device or medicinal product, within the past 3 months, with the exception: if co-enrolment is not considered to impact adverse events or outcomes in the opinion of the Chief Investigator. (A live document containing a list of approved studies will be included in a reference document made available to all study sites and available upon request)
7. Contraindications for the use of the geko™ device:

* Allergy to hydrogel constituents
8. Contraindications to IPC:

* Severe peripheral vascular disease
* Large leg ulcers requiring extensive bandaging (small ulcers or skin breaks with flat coverings are not an exclusion)
* Severe oedema
* Leg deformities making appropriate fitting impossible
9. Uncontrolled congestive cardiac failure
10. Pregnancy
11. Single or double leg amputations
