Endometriosis Clinical Trial
— EASYlightOfficial title:
Esketamine as Treatment for Chronic Pain Due to Endometriosis: a RCT Study
The goal of this randomized controlled trial is to investigate the effect of esketamine versus placebo on the NRS score for chronic pelvic pain. Secondary endpoints are to assess pain scores, side-effects, quality of life, depressive symptoms and pain coping.

Exclusion Criteria: - Pain score <6 out of 10 (NRS) for chronic pelvic pain - Endometriosis affecting the bladder and ureter - Increased intracranial pressure - Poorly regulated hypertension, >180/100mmHg at rest - Patients with thyroid disease - Patients with cancer - History of psychiatric illness (schizophrenia, psychosis, delirium, manic depression) - Serious medical disease (e.g., cardiovascular, renal , pulmonary or liver disease) - Severe liver disease - Patients with glaucoma - Usage of strong opioid medication - Usage of xanthine derivatives or ergometrine - Unstable angina, heart failure, history of cerebral vascular accident (CVA) - Patients suffering from an active infection - Patients with epilepsy - Patients trying to achieve pregnancy and or patients who are breastfeeding - Not being able to answer questionnaires (in Dutch) - Mentally incompetent (patients not able to make decisions that are in their best interests, this will be evaluated by their treating physician (e.g. patients with an intellectual disability or mental retardation)) - Alcohol or drug abuse - Patient with a known (es)ketamine allergy - Abnormal liver enzyme levels at baseline (ASAT, ALAT, GGT, AF, Bilirubin total) Patients are allowed to continue the following pain medications: paracetamol, non-steroidal anti-inflammatory drugs as described previously by Sigtermans et al. (Trial NL466 (NTR507))* according to their stable use in dose and frequency. *in case of tramadol, amitriptylin, selective serotonin reuptake-inhibitors, gabapentin and pregabalin, the usage may also be continued during this study. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Chronic pelvic pain | The effect of treatment allocation on the NRS score for chronic pelvic pain. The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | 4 weeks after the 8 hour infusion treatment. | |
Secondary | Dysmenorrhea | NRS score for dysmenorrhea. The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Dyschezia | NRS scores for dyschezia.The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Dysuria | NRS scores for dysuria. The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Dyspareunia | NRS score for dyspareunia. The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Chronic pelvic pain | NRS score for chronic pelvic pain. The NRS scale ranges from 0 (no pain) to 10 (worst pain imaginable). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Depressive symptoms | Hospital Anxiety and Depression scale, 14 questions, scale from 0-3, higher scores mean worse outcome. | Baseline, 4 weeks after infusion treatment | |
Secondary | Endometriosis associated Quality of Life | Endometriosis Health Profile-30 (EHP-30). The overall EHP-30 score ranges from 0 to 100, with a high score indicating poorer health-related quality of life. | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Quality of life in general | EuroQql five-dimensional 5 levels (EQ-5D-5L). According to the Dutch scoring algorithm, the EQ-5D-5L score index value ranges from -0.446 (55555 worst health state) to 1 (11111, best health state). | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Quality of life in general | EuroQql Visual Analog Scale (EQ-VAS). Overall health will be represented by the EQ-VAS, ranging from 0 to 100, with higher scores indicating better health. | Baseline and week 4, 8, 12 after the 8 hour infusion treatment | |
Secondary | Productivity costs | Adjusted productivity costs questionnaire (iPCQ): institute for Medical Technology Assessment (iMTA). Adjusted medical consumption questionnaire: iMTA. Productivity costs will be measured by calculating absence from paid work (absenteeism), reduced productivity at paid work (presenteeism), and productivity loss in unpaid work. Hours of productivity loss will be translated by a standard cost price of productivity per hour. | 12 weeks post-infusion treatment | |
Secondary | Medical costs | Medical consumption costs will be calculated based upon the iMCQ. | Baseline, 12 weeks post-infusion treatment | |
Secondary | Pain coping and cognition | Pain Coping and Cognition list (PCCL), consists of 42 items divided in four scales: pain catastrophising (higher scores mean a higher degree of catastrophising), pain coping (lower scores mean a lower degree of pain coping), internal pain control (lower scores mean less internal pain control) and external pain control (higher scores mean less external pain control. | Baseline, 12 weeks post-infusion treatment | |
Secondary | The effect infusion treatment psychedelic effects | Bowdle questionnaire, scale from 0-100, higher scores mean worse outcome. | On the day of infusion (prior to infusion and during infusion) | |
Secondary | Treatment experience | 1 question, treatment rating on a scale from 0 (worst experience possible) -10 (excellent experience) | Directly after infusion |
