|
E.1.1.1 | Medical condition in easily understood language |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Musculoskeletal Diseases [C05] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The objective of this proposal is to investigate if duloxetine is effective as a third choice pain medication for treating chronic pain in OA compared to usual care |
Deze studie wil antwoord geven op de vraag of duloxetine effectief is als derdelijns pijnmedicatie voor chronische pijn bij artrose in vergelijking met de gebruikelijke zorg (bij falen of contra-indicaties voor een NSAID). |
|
E.2.2 | Secondary objectives of the trial |
Furthermore, we will assess the cost-effectiveness of duloxetine treatment and if the presence of a neuropathic pain component favorably modifies the response to treatment and if the presence of a neuropathic component will be necessary for (cost-)effectiveness. |
Daarnaast zal worden gekeken of duloxetine kosteneffectief is. Tenslotte zal worden bekeken of de aanwezigheid van een neuropathische pijn component de respons op behandeling verbetert en of deze karakteristiek noodzakelijk is voor een kosteneffectieve behandeling. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1) having hip or knee OA based on the clinical ACR criteria, and 2) having chronic pain (most days of the last three months) in hip or knee, and 3)either: (i) a contra-indication for NSAIDs, (ii) adverse reactions of NSAIDs; or (iii) insufficient benefit of NSAIDs. |
1) Heup- of knieartrosepatiënten (gebaseerd op de klinische ACR-criteria), met 2) chronische pijn (meeste dagen in de afgelopen 3 maanden) in de heup of knie en 3) (i) contra-indicatie voor NSAID's, (ii) bijwerkingen van NSAID's of (iii) onvoldoende effect NSAID's |
|
E.4 | Principal exclusion criteria |
1) on waiting list for hip/knee replacement, and 2) use of antidepressants and neuropathic pain medication 3) contra-indication of duloxetine (use of Monoamine Oxidase Inhibitors, having uncontrolled narrow-angle glaucoma, in combination with (other) central nervous system acting drugs, in combination with thioridazine, hypersensitivity to duloxetine, disturbed liver function, renal insufficiency (creatinine clearance <30 ml/min), usage of strong CYP1A2-inhibitors and CYP2D6-inhibitors and substrates) |
1) op de wachtlijst staan voor een nieuwe heup of knie, 2) gebruik van antidepressiva en neuropathische pijnmedicatie 3) contra-indicaties voor duloxetine (gebruik van Monoamine Oxidase Inhibitors, ongecontroleerde nauwe kamerhoek glaucoom, in combinatie met (andere) medicatie die op het centrale zenuwstelsel werkt, in combinatie met thioridazine of bij hypersensitiviteit voor duloxetine, gestoorde leverfunctie, ernstige nierfunctiestoornis (creatinine klaring <30 ml/min), gebruik van sterke CYP1A2-inhibitoren en CYP2D6-inhibitoren en substraten) |
