Clinical Trial Summary

Thumb osteoarthritis or trapeziometacarpal osteoarthritis (TMO) is a common and painful form of hand arthritis that limits thumb mobility and hand function, affecting patients' quality of life. Although corticosteroids injections are a typical treatment, their effectiveness has been challenged, and side effects have been reported. Recent studies suggest that saline injections, usually considered inactive, might be a viable treatment option. The primary goal of this study is to compare the effectiveness of saline injections versus corticosteroids injections in reducing TMO-related pain and improving hand function. In this study, 40 people with TMO will be randomly assigned to receive either a corticosteroids or a saline injection, without them or the doctors performing the injection knowing which one was administered (double blind). If saline injections prove more effective, they could provide a less harmful and cheaper therapeutic alternative for TMO patients.


Description:

Trapeziometacarpal osteoarthritis (TMO) is one of the most painful, disabling and prevalent hand osteoarthritis. One of the most common treatments for TMO is an intra-articular corticosteroids injection. However, non-superiority of corticosteroids injection over placebo to reduce pain has also been reported for TMO and other types of osteoarthritis (knee, hip, or shoulder). Furthermore, adverse effects of corticosteroids injection such as subcutaneous atrophy, tendon ruptures, and articular cartilage damage have been reported. Given the uncertain relevance of corticosteroids injection as a therapeutic agent, it becomes imperative to consider alternative options. In fact, three systematic reviews suggest that saline injections may be a viable option for TMO or knee pain. To investigate the hypothesis that saline injection is a more effective modality than corticosteroids injection for the treatment of TMO in terms of reducing TMO pain and improving hand function, we must undertake a large, randomized trial in real clinical settings to ensure the acquisition of high-quality evidence. This pilot project is a preparatory phase for a larger study aimed at comparing the effectiveness of saline and corticosteroids injections in treating TMO, focusing on pain reduction and functional improvements. The study design is a pragmatic, multicenter, double-blind randomized trial, adhering to PRECIS-2 guidelines. The pilot randomized controlled trial will assess the feasibility of a multicenter study by evaluating aspects such as recruitment capabilities, treatment adherence, and the success of blinding techniques for participants and clinicians. It will also identify potential challenges and gather preliminary data to support a funding application for the full-scale study. Recruitment and data collection are planned over a 12-month period, targeting 40 participants initially to refine procedures and validate the study's feasibility. Participants will be randomly assigned to treatment, and the clinicians delivering the intervention will be blinded to the content of the injections. The study's primary outcome will measure pain intensity using a numeric scale at multiple time points, while secondary outcomes include upper limb functional limitations using the QuickDASH scale. These will be measured at baseline, before treatment, and at follow-up, 1, 3, and 6 months after treatment.

Outcome

Type Measure Description Time frame Safety issue
Other Rate of participant recruitment The number of participants recruited per week, divided by those assessed for eligibility and those included Through study completion (estimated time, 1 year)
Other Rate of participants completing the initial assessment The number of participants completing initial assessments, divided by those recruited Through study completion (estimated time, 1 year)
Other Rate of participants receiving the injection The number of participants receiving the injection, divided by those recruited Through study completion (estimated time, 1 year)
Other Rate of participants completing the follow-ups The number of participants completing the follow-ups at 1, 3, and 6 months, divided by those recruited Through study completion (estimated time, 1 year)
Other Success of blinded procedures for patients Success of blinded procedures for patients will be investigated by asking them to guess which treatment they will have received via the post-injection questionnaire. Three response categories for treatment guess are 'corticosteroid injection', 'saline injection', or 'I don't know', after the last follow-up). 1, 3, and 6 months after receiving the injection
Other Success of blinded procedures for clinicians Success of blinded procedures for physicians will be by asking them by email after the injection to guess which treatment they administered. Three response categories for treatment guess: 'corticosteroid injection', 'saline injection', or 'I don't know'. Up to 24 hours after each injection
Other Hospital Anxiety and Depression Scale 14-item questionnaire to assess anxiety and depression symptoms among non-psychiatric patients. It generates an Anxiety score and a Depression one from 0 to 21 where a higher score indicates greater distress. Anxiety Scores = 10 and Depression Scores = 7 are considered clinically significant. Baseline, 1, 3, and 6 months after injection
Other Adverse events Side effects will be reported systematically by using a questionnaire with 5 items assessing the presence, type, frequency, severity and duration of injection-related adverse events. 24 hours after the injection and at 1-month, 3-month- and 6-month post-injection.
Primary Trapeziometacarpal pain intensity Three types of pain intensity (current, on the average in the last 7 days, at its worst in the last 7 days) will be measured using a 0-10 rating scale (0 = no pain and 10 = worst pain possible) Baseline, 1, 3, and 6 months after injection
Secondary QuickDASH questionnaire (short version of the 30-item Disabilities of the Arm, Shoulder and Hand). 11-item questionnaire assesses the level of physical function and symptoms among patients with upper limb musculoskeletal condition. The total score ranges from 0 to 100 and the higher it is, the more disabled is the patient. Baseline, 1, 3, and 6 months after injection
