Comparison of the Efficacy, Tolerability and Safety of actiTENS to Those of Level 2 Analgesic Treatments.
- Conditions
- Knee Osteoarthritis
- Interventions
- Device: ActiTENSDrug: Level 2 Analgesic Treatments
- Registration Number
- NCT03902340
- Lead Sponsor
- Sublimed
- Brief Summary
This is a phase 3, multicentre, prospective, single-blind on principal efficacy criterion, 2 parallel groups, randomized, controlled clinical study comparing efficacy and safety of actiTENS versus systemic level 2 analgesics recommended for the treatment of moderate or severe, nociceptive, chronic pain in patients suffering from osteoarthritis of the knee.
- Detailed Description
Osteoarthritis (OA) is a debilitating chronic condition requiring long-term treatment of pain and inducing functional impairment. More specifically knee osteoarthritis (KOA) is a common disease associated with significant morbidity. Its prevalence increases with age dramatically. KOA is frequently associated with pain which can worsen with daily activities. The goals of KOA treatments are to provide pain relief and to improve function and quality of life. For the American college of Rheumatology and despite the frequent use of TENS in treating patients with KOA, questions remained regarding its efficacy. Consequently TENS needs additional clinical studies to demonstrate its efficacy in management of painful osteoarthritis.
The main objective of this study is to demonstrate the efficacy and to the safety of TENS in the management of chronic, nociceptive pain in patient suffering from KOA.

Group Intervention Description TENS ActiTENS Treatment by non-pharmacological transcutaneous electric nerve stimulation (TENS) level 2 systemic analgesic treatments Level 2 Analgesic Treatments Treatment by level 2 analgesic pharmacological treatment indicated in the treatment of chronic nociceptive pain of moderate to severe intensity.
- Primary Outcome Measures
Name Time Method Efficacy : pain intensity evaluated by a numerus scale from 0 to 10 3 months after dosing Pain intensity (PI) at M3 between both treatment groups. Numerus scale with a minimum of 0 (no pain) to a maximum of 10 (maximum pain).
Safety : occurence of adverse events 3 months after dosing Number of adverse events (AE) occurred during the 3 months of follow-up and due to studied treatments.
- Secondary Outcome Measures
Name Time Method Efficacy : drop-outs for inefficacy Through study completion, an average of 6 months Evaluation of the number of patient drop outs because of treatment inefficacy in each arm
Efficacy : prolongation of studied treatment Through study completion, an average of 6 months Evaluation of the number of patient wishes to continue the studied treatment.
Safety : occurrence of Adverse Events (AE) Through study completion, an average of 6 months Evaluation by the type of AE and the date of occurence
Efficacy : patient global impression of change evaluated by a global impression questionnaire. 1, 3 and 6 months after dosing Evaluation of the change on activity, symptoms, emotions, quality of life regarding the pain of patient at M1, M3 and M6
Efficacy : pain relief (PAR) evaluated by the pain visual analogue scale (VAS) 1, 3 and 6 months after dosing Pain relief at M1, M3 and M6. VAS from 0 to 10 with 0 = no relief and 10 = total relief). Scale of 100 mm.
Efficacy : quality of life evaluated by the questionnaire EuroQol-5D 1, 3 and 6 months after dosing Evaluation of the quality of life at M1, M3 and M6
Efficacy : pain intensity evaluated by a numerus scale from 0 to 10 1, 3 and 6 months after dosing Minimum, maximum,median and difference of pain intensity (PI) during movement and at rest at M1, M3 and M6 between both treatment groups
Safety : drop-outs for AE and corrective treatments Through study completion, an average of 6 months Evaluation of the number of patient drop outs because of the occurence of adverse events in each arm
Efficacy : functional status evaluated by the WOMAC score (Western Onatario McMaster score) 1, 3 and 6 months after dosing Functional status (pain, function, stiffness) at M1, M3 and M6.
Estimation of direct costs. Through study completion, an average of 6 months Comparison of treatment costs between the two arms
