About this study

Official title: Clinical Implications of FKBP5 in Post-stroke Neural Plasticity and Neuromodulation Effects

With contemporary lifestyle changes and global aging, it is important yet unknown how stress interacts to post-stroke outcomes. This proposal aims to study the link between the stress-responsive FKBP51-related pathways and neural plasticity after stroke, elucidating FKBP5 gene polymorphisms and blood FKBP51 regulation in relation to brain excitability and functions, understanding the effects of transcranial direct current stimulation, and characterizing brain mechanisms for individualized early rehabilitation after stroke.

Read the detailed description

Stress is an underestimated risk factor and also a consequence of cardiovascular diseases and stroke. FK506-binding protein 51 (FKBP51) modulates stress responses by acting as a co-chaperone that negatively regulates glucocorticoid receptor (GR) to cortisol binding and nuclear signaling. In an oxygen-glucose deprivation (OGD) model of acute mouse hippocampal slices, FKBP5 deletion reduced ischemic neuronal hyperexcitation, and cathodal electrical stimulation of OGD-injured wild-type decreased FKBP51 levels. However, clinical implications of FKBP5 polymorphisms and FKBP51 regulation in post-stroke outcomes and neuromodulation-induced plasticity are unknown. We aim to assess the link between FKBP5 polymorphisms and blood FKBP51 regulation after stroke, and their relationship with stroke phenotypes, brain connectivity and functional outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Bihemispheric tDCSDevice

    The anode and cathode are placed over the ipsilesional and contralesional primary motor cortex (C3 or C4 based on 10-20 system), respectively. The size of the electrode is 5x5 cm.

Study groups in NCT05198037
Study groupRoleWhat they receive
Active transcranial direct current stimulation (tDCS)ExperimentalWeak direct currents with 2 mA are delivered 20 minutes per session (including 30s ramp-up and 30s ramp-down) during tailored upper extremity task practice. Total sessions are 20 over 10 days.
Receives: Device: Bihemispheric tDCS
Sham tDCSSham comparatorThe device is automatically shut down after 2-minute stimulation. Treatment sessions and frequency are the same as the Experimental arm.

Questions about this trial

What is this clinical trial studying?

A study testing Bihemispheric tDCS in people with Stroke, run by Taipei Veterans General Hospital, Taiwan at 1 site in Taiwan.

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 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 20 Jan 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

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

Contact I-Hui Lee, MD, PhD (+ 886-2-28712121 ext. 8109, ihlee@vghtpe.gov.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fugl-Meyer Assessment of Upper Extremity, FMA-UE (time frame: Change score from baseline (~10 days poststroke) to 90 days poststroke). 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 20 Jan 2022.
