Brief Summary

Intravenous administration of esketamine is an effective recognized therapeutic option in refractory pain in CRPS, which sometimes in at least a part of the patients has a prolonged therapeutic effect. Unfortunately, CRPS literature contains a wide range of ketamine dosing regimens with the result that clinical protocols on dosage and administration are very heterogeneous. The current esketamine regimen in Erasmus MC consists of a 6-day hospital admission for continuous administration. In the Netherlands, both inpatient and outpatient esketamine treatments are offered. Inpatient and outpatient ketamine treatments have never been compared in randomized controlled trials and it is therefore unknown whether these two dosing regimens are equally effective. The primary objective is to demonstrate non-inferiority of experimental esketamine administration of 6x 1 day per 2 weeks (in total 3 months) as compared with standard esketamine administration of 1x 6 consecutive days. The end of study is at 6 months after the start of the study/treatment.

Outcome Measures

Primary Outcomes (1)

• Change from baseline pain scores

  Pain intensity measured by Numerical Rating Scale (NRS). Minimum value=0 and maximum value is 10. Higher scores mean a worse outcome.

  Baseline (week 0), During inpatient or outpatient esketamine infusion (week 1 for inpatient protocol / week 1, 3, 5, 7, 9, 11 for outpatient protocol), During telephone consultation (week 1, 3, 5, 7, 9, 11), Follow-up (3 months), End of study (6 months)

Secondary Outcomes (11)

• Change from baseline Quantitative Sensory Testing

  Baseline (week 0) and follow-up visit (week 12)

• Change from baseline Thermography

  Baseline (week 0) and follow-up visit (week 12)

• Adverse events due to S-ketamine infusion

  During inpatient or outpatient esketamine infusion (week 1 for inpatient protocol / week 1, 3, 5, 7, 9, 11 for outpatient protocol), During telephone consultation (week 1, 3, 5, 7, 9, 11)

• Change from baseline pain medication dose

  Baseline (week 0), follow-up visit (3 months) and end of study (6 months)

• Change from baseline Complex Regional Pain Syndrome severity score

  Baseline (week 0) and follow-up visit (3 months)

Study Arms (2)

Outpatient

EXPERIMENTAL

The experimental intervention group visits the outpatient clinic to receive intravenous esketamine in day-care setting every 2 weeks for 3 months.

Drug: S-ketamine infusion outpatient setting

Inpatient

ACTIVE COMPARATOR

The standard treatment group receives intravenous esketamine for 6 consecutive days in hospital.

Drug: S-ketamine infusion inpatient setting

Interventions

S-ketamine infusion inpatient setting DRUG

S-ketamine is administered intravenously for six consecutive days. The administered dose of S-ketamine is 50 mcg/kg/h and can be increased to a maximum of 200 mcg/kg/h.

Also known as: ketamine, esketamine

Inpatient

S-ketamine infusion outpatient setting DRUG

S-ketamine is administered intravenously for six hours. The administered dose of S-ketamine is 50 mcg/kg/h and can be increased to a maximum of 200 mcg/kg/h.

Also known as: ketamine, esketamine

Outpatient
