Amantadine for Neuroenhancement in Acute Patients Study

Germany50 participantsStarted 2023-03-01

Plain-language summary

Introduction: Many patients on intermediate care (IMC) and intensive care units (ICU) suffer from reduced consciousness. In this situation, a treatment attempt with Amantadine is often undertaken. While clinicians report good results with this approach, the treatment is off-label and the scientific evidence limited. Study design: Monocenter, phase IIb, proof of concept, open-label pilot study. Methods: 50 intensive care patients with reduced consciousness not otherwise explained will be treated with Amantadine for 5 days. Vigilance is checked before, during and after treatment (on discharge and after 3 months) using electroencephalography (EEG) and established clinical tests, for instance Glasgow Coma Scale (GCS), Glasgow Outcome Scale - Extended (GOS-E), Coma Recovery Scale Revised (CRS-R) and others. Results: The primary endpoint "improvement of the GCS scale from screening to day 5 of at least 3 points" is analysed according to the Simon design. The secondary endpoints (GCS continuous scale, modified Rankins Scale (mRS), National Institute of Health Stroke Scale (NIHSS), GOS-E, CRS-R and Montreal Cognitive Assessment (MoCA) after 90 days, Richmond Agitation-Sedation Scale (RASS) and Intensive Care Delirium Screening Checklist (ICDSC) will be analysed by mixed models with time (categorically coded) as only factor including all measurements up to 3 months follow up. Discussion: The investigators aim to shed light on an established clinical practice without sufficient scientific evidence. The investigators are aware that the power of our study is limited by design (no control group, no blinding). However, if successful, this study may be the basis for a randomized controlled trial in the future.

Inclusion criteria

. Vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the WOCBP trial participant and that the vasectomized partner has received medical assessment of the surgical success
. In the context of this guidance sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Level of vigilance measured by change in the Glasgow Coma Scale (GCS); a patient is defined as responder if his/her score increases by at least 3 points.

Timeframe: Assessment will take place before treatment (baseline value) and after 120 hours after treatment begin.
