About this study
Official title: Use of Analgesic Treatment to Reduce Signs of Pain in Patients With Disorders of Consciousness: a Double-blind Placebo-controlled Clinical Study.
The purpose of this study is to characterize and improve pain and nociception management in patients with disorders of consciousness (DOC). This project is divided into two phases, a first phase to evaluate pain level and a second phase which consist of a clinical trial to evalute pain medication efficacy.
The main aim is to evaluate the use of the Nociception Coma Scale-Revised (NCS-R) and its cut-off score (i.e., 5) as an assessment and management tool to define guidelines for managing pain in patients with DOC. In this double-blind, placebo-controlled clinical study, we will evaluate the use of analgesic treatments in reducing pain in subacute/chronic patients. The project will also allow us to validate the NCS-R cut-off score defined previously.
Read the detailed description
The study will be performed within one week (i.e, 7 days) and consists of two phases:
- Phase 1 "Patients selection (D0)": Patients will be assessed by the NCS-R during experimental stimulation (rest, tactile, noxious) and mobilizations (physiotherapy). Patients with potential pain will be included in the phase 2.
- Phase 2 "Analgesic administration (D1 and D2)": double-blind placebo-controlled randomized clinical trial on potential responders identified in phase 1. A medical doctor of our team will suggest to the physician in charge to prescribe the dedicated medication. One placebo and one real treatment will be administered on day 1 and 2 by the nurses at least half-hour before the physiotherapy. Randomization between day 1 and 2 will be applied at that time.
For each day of phase 1 and 2, several assessments will be performed: NCS-R, CRS-R and spasticity assessment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Analgesic administrationDrug
- Level 1 : Paracétamol 1g/Acetaminophène 1g, Ibuprofène 600mg, Diclofénac 50mg.
- Level 2: Tramadol 50mg.
- Level 3: Oxycodone 5mg, Morphine sulfate 10mg.
- Increase of a prior level 3 medication :
- 1/6 of the total dose of daily level 3 medication (e.g. the patient receives 30mg of oxycodone a day. He will be administered a single dose of 5 mg for the study), defined as a breakthrough dose in the management of chronic pain. To standardize the treatment, the dose of the prior level 3 medication will be converted to oxycodone. Several online tools exist to do the conversion between opioids (e.g. mobile app Orthodose ®).
- If the oral intake or the gastrostomy use is not possible, the breakthrough dose will be administered by subcutaneous route. The dose will also be 1/6 of the daily dose and will be converted to injectable morphine. Conversion to injectable morphine will be performed with any equivalence tool (such as the mobile app Orthodose ®)
Placebo administrationDrug
Folavit (folic acid, 0.4 mg)
| Study group | Role | What they receive |
|---|---|---|
| Analgesic administration | Active comparator | The analgesic treatment will be tailored to the patient's medication and will be based on 3 levels (based on Ventafridda et al., 1985):
* Level 1 : Non-opioid analgesics
* Level 2 : Weak opioids analgesics
* Level 3 : Strong opioids analgesics
If the patient is already on pain medications, we will add the lowest effective dose of the level above the level of the regular pain medications of the patient. (e.g. if the patient has no analgesic treatment, he will be given a non-opioid analgesic (level 1). If he already has a level 1 treatment, we will go for level 2 medication. If he has level 2 treatment, we will go for level 3. And if the patient is already at level 3, we will increase the dosage by steps (reference: 5mg oxycodone as first choice for level 3 drugs)). Preferably, the medication will be administered by oral intake or gastrostomy feeding tube. If it is not possible, other routes of administration are allowed. Receives: Drug: Analgesic administration |
| Placebo administration | Placebo comparator | Folavit capsules will be used as a placebo Receives: Drug: Placebo administration |
What is being measured
The primary outcome is the main question the study is designed to answer.
Nociception Coma Scale-Revised (NCS-R)
The NCS-R (Chatelle et al., 2012) is used to assess the perception of acute pain in patients with disorders of consciousness. It is composed of 3 subscales (motor, verbal and facial expressions) respectively scoring from 0 (no response) to 3 (highest response level). Here the NCS-R is administered in 4 different conditions: at rest, during tactile stimulation, during experimental nociceptive stimulation (pressure on the bed of the left and right nail) and during mobilization (physiotherapy).
Measured: through study completion, an average of 2 years
Coma Recovery Scale-Revised (CRS-R)
The CRS-R (Giacino et al., 2004) is the gold standard for the behavioural assessment of the level of consciousness and is widely used in patients with chronic disorders of consciousness. The CRS-R is composed of six subscales that assess the following domains: visual, motor, auditory and oro-motor/verbal functions, as well as communication, and arousal. The score ranges from 0 to 23, in which the lowest score indicates coma and the highest score indicates the emergence from the minimally conscious state. The diagnosis is made according to the presence\absence of particular behavioural responses.
Measured: through study completion, an average of 2 years
Secondary outcomes (1)
Modified Ashworth Scale (MAS)
The MAS (Bohannon et al., 1987) is used to assess spasticity (reflex contraction in response to passive stretching). This is a scoring scale from 0 (no increase in muscle tone) to 4 (very strong increase in tone, stiffness), which will depend on the speed of execution of the movement (the faster the limb will be mobilized the more spastic it will be) and which must be performed at least 3 times for each joint.
Measured: through study completion, an average of 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Analgesic administration in people with Disorders of Consciousness and Severe Brain Injury, run by University of Liege at 1 site in Belgium.
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 5 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: finished, as of the sponsor's last update on 3 May 2021. 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 Belgium. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Nociception Coma Scale-Revised (NCS-R) (time frame: through study completion, an average of 2 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04330547, which also lists 4 linked publications.
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 3 May 2021.
