Overview
Sponsor-declared trial summary
Complex regional pain syndrome
The aim of this study is to assess whether a series of esketamine infusions, every 2 weeks for 3 months, in a day treatment setting, is non-inferior at 3 months after the start of the treatment to the standard treatment of a 6-day clinical admission of continuous esketamine administration.

Main objective
Scope: Efficacy, Therapy
The aim of this study is to assess whether a series of esketamine infusions, every 2 weeks for 3 months, in a day treatment setting, is non-inferior at 3 months after the start of the treatment to the standard treatment of a 6-day clinical admission of continuous esketamine administration.
Secondary objectives 6
- Number and severity of intervention related adverse events in each of the esketamine administration regimens
- To assess protocol deviations due to logistical problems for each of the administration regimens
- Physiological measures: Questionnaires COMPACT (Core Outcome Measurement set for complex regional PAin syndrome Clinical sTudies)
- Objective measures: Quantitative Sensory Testing (QST), thermography, serum levels and cellular immunity samples
- NRS-pain scores over time till 6 months follow-up
- Dose reduction of pain medication at follow up

Eligibility criteria
Principal inclusion / exclusion criteria as submitted by sponsor
Inclusion criteria 6
- Age ≥ 18 years
- Meeting the new International Association for the Study of Pain (IASP) diagnostic criteria for CRPS (“the Budapest Criteria) or having met the new IASP diagnostic criteria of CRPS (“CRPS with Remission of Some features”)
- Willing and capable to participate in the study.
- CRPS in one upper extremity and/or CRPS in one lower extremity
- Treatment in an elective setting
- Adequate comprehension of the Dutch language
Exclusion criteria 1
- Contraindications to and precautions for use of subanesthetic doses of ketamine for chronic pain are listed by Cohen et al. and the Dutch CRPS guidelines and our clinical protocol
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- Pain intensity measured by Numerical Rating Scale (NRS). The current NRS score reflecting the pain intensity at the moment when asked and the average NRS score of the last 24 hours. (T0, T3, T4)
Secondary endpoints 10
- To assess protocol deviations due to logistical problems for each of the administration regimens: premature termination (due to i.e. bed capacity problems), waiting time for therapy (weeks) and compliance of the patients. (T1, T2)
- Number and severity of intervention related adverse events: Psychomimetic (dysphoria, euphoria, hallucinations, nightmares and vivid dreams, anxiety, agitation), blurry vision or diplopia, nausea and / or vomiting, sedation, hepatic toxicity, headache and dislocation of peripheral intravenous catheter (T1, T2)
- Number of administered co-interventions related to adverse events (benzodiazepines, clonidine, granisetron). (T1)
- NRS pain scores over time till follow-up T3. The current NRS score reflecting the pain intensity at the moment when asked by telephone and the average NRS score of the last 24 hours. (T1, T2)
- Objectively measured effects of each of the administration regimens on the inflammation; serum levels of sIL-2R and sCD163 will be detected with Enzyme Linked Immunosorbent Assay (ELISA) as measures for T-lymphocyte and macrophage activation, respectively. In addition, T cell populations and monocyte populations will be identified using flow cytometry. (T0, T3)
- To assess the sensory-discriminative dimensions of pain before and after ketamine treatment; Quantitative Sensory Testing (T0, T3)
- Objectively measured effects of each of the administration regimens on symptoms vasomotor disturbances; Thermography (T0, T3)
- Dose reduction of pain medication at follow after three months and six months (T3, T4)
- CRPS symptoms and signs based on the Budapest diagnostic clinical criteria; CRPS severity score (20). (T0, T3)
- Questionnaires COMPACT (Core Outcome Measurement set for complex regional PAin syndrome Clinical sTudies) (42, 43):
