Clinical Trial Summary

Rheumatoid arthritis (RA) is a chronic inflammatory disease primarily affecting the small joints of hands and feet, but may also present with systemic, extraarticular features. The Swedish Rheumatology Quality Register (SRQ) is a nationwide quality register with the aim of continuously improving the treatment and follow-up of patients with rheumatic disease. Using this type of quality registers, it is possible to perform a Registrybased Randomised Clinical Trial (R-RCT), that is a randomised clinical trial this is carried out by screening, recruitment and registration of study data is performed based on information given by a quality register. All patients with newly diagnosed RA are included in SRQ. Treatment options for RA include different types of immunosuppression and corticosteroids as bridging therapy. Methotrexate, a synthetic conventional disease modifying antirheumatic drug (csDMARD), which can be given either orally or subcutaneously, is considered a first-line treatment. Studies have shown the beneficial efficacy and improved quality of life for patients with RA treated with methotrexate, however this is not studied in a setting of unselected patients with newly diagnosed RA in northern Sweden. Moreover, it is not known to what extent patients prefer oral or subcutaneous administration route, or if there are any health economic benefits from either of the two administration routes. Further, changes in gut microbiota is not studied in this setting.

Description:

Rheumatoid arthritis (RA) is a chronic inflammatory disease primarily affecting the small joints of hands and feet, but may also present with systemic, extraarticular features. Pain and stiffness induced by rest, fever, fatigue, and weight loss are common constitutional symptoms. After onset of symptoms the patient most often sees a general practitioner for referral to a rheumatology department. After diagnosis of RA treatment is indicated to start as soon as possible to prevent future disability. Treatment options for RA include different types of immunosuppression and corticosteroids as bridging therapy. Methotrexate (MTX) has been used for decades as the most commonly prescribed synthetic conventional disease modifying antirheumatic drug (csDMARD) in the treatment for RA. MTX can be given either orally or subcutaneously, although the most commonly used route is still per oral, largely due to convenience. Studies have shown the beneficial efficacy and improved quality of life with methotrexate treatment. Although its mechanism of action has not been fully elucidated, current evidence supports that it works by acting as both an antimetabolite (by inhibiting dihydrofolate reductase) and an immunomodulatory agent (by promoting adenosine release, thereby suppressing inflammation). MTX has long been used as a standard of care to treat RA at typically between 7.5 and 30.0 mg/week in a single weekly dose. Methotrexate has a broad spectrum of adverse effects, one of which is the most common is gastrointestinal manifestations. In our clinic, the standard clinical practice is to start with per oral administration and then a switch from oral medication to subcutaneous injections in cases where gastrointestinal adverse effects occur or a failure to reach remission. When given subcutaneously, the bioavailability of methotrexate increases which thereby is thought to enhance the efficacy of methotrexate. A recent metanalysis showed that subcutaneously given MTX therapy has significantly higher odds than single dose weekly oral MTX of achieving reduction in disease activity, with no increased adverse effects. However, this metanalysis also pinpoints the fact that studies in this area is surprisingly few, i.e. this metanalysis is only based on four original publications.

The Swedish Rheumatology Quality Register (SRQ) is a nationwide quality register with the aim of continuously improving the treatment and follow-up of patients with rheumatic disease. SRQ has been granted certification level

1, which is the highest level a national quality register can obtain. Using this type of quality registers, it is possible to perform a Registrybased Randomised Clinical Trial (R-RCT) that are defined as prospective randomised studies that to some extent use registers for their implementation, that is for example a randomised clinical trial carried out by screening, recruitment and registration of study data based on information given in a quality register. Studies have also proposed an effect on gut microbiota both by the RA disease itself as well as by treatment with methotrexate. There is increasing knowledge that the gut microbiota are not only involved in the digestion and absorption of food, but they can also exert a protective function by preventing adherence of pathogenic bacteria to the mucosal layer, and they play a pivotal role in modulating the innate and acquired immunity of the host. Remarkably, gut microbiota exert their effects not only in the intestine but can signal to distant organs in the body, thereby explaining their association with several diseases, including RA. From a clinical perspective, elucidation of the interaction between RA, MTX and the gut microbiota could reduce the costs and harm to patients that is caused by "trial and error" use of drugs with highly variable treatment responses. Patient acceptability is particularly significant in dictating adherence to therapy.

A potential drawback to subcutaneous MTX is patients' fear of needles and/ or the discomfort of selfinjecting; however, this doubt has been strongly reassured with the advent of the widely accepted biologics which require self-injection. Recent studies examined patient preferences for RA treatment in several populations, finding that most participants were willing to accept certain risks of adverse effects to gain potential benefits, however there seem to be a variability in patient preferences for RA treatment, highlighting the importance of incorporating patient input into the treatment approach. Previous studies have mainly focused on patients with established RA, showing that many patients place a high value on treatment benefits over other treatment attributes, including side effects, cost, or route of administration (9) and also an expectance for injections of MTX in patients with long standing RA. However, patient preference studies are scarce in patients with newly diagnosed disease and in our part of the world. For patient preference study a (threshold technique) TT exercise is often used. Here a decisionmaker, typically a patient or physician is presented with a choice between two treatment or healthcare delivery options. One is the reference option that is the baseline against which an alternative is compared. It is often the option associated with the status quo or standard of care. The second is the target option and confers both an incremental benefit and an incremental burden relative to the status quo or standard of care. Once the reference and target options have been identified, the researcher must identify the key attribute of the target option (either a benefit or a burden) that will be used to estimate the strength of preference for the target relative to the reference option. The key attribute can be any attribute for which values can be expressed numerically. The most common key attributes are probability of benefit, risk of harm, waiting time, life expectancy, and cost. When the key attribute is a measure of burden (e.g., risk of harm, waiting time, or cost), the estimated threshold is a measure of the additional burden that exactly offsets the incremental benefit of the target option. If the key attribute is a benefit (e.g., probability of benefit or life expectancy), the estimated threshold is a measure of the minimum additional benefit that the target must provide to offset the incremental burden of that option. After being presented with descriptions of the two options, respondents real-world options with well-known attributes, using all available information in the initial question, including known differences between the options in the value of the key attribute, may provide a direct measure of decision makers' preference between the reference and target options in addition to providing a starting point for estimating the threshold value of the key attribute. If the reference option is chosen in the initial question, the key attribute of the target is made better or more appealing and the question is repeated. If the target is chosen initially, the key attribute of the target is made worse or less appealing and the question is repeated. The process continues until the researcher can identify the threshold level of the key attribute, i.e., the level at which a respondent is indifferent between the reference and target options. The difference between the threshold value of the key attribute and the level of the same attribute in the reference option is a measure of the strength of preference for the target option compared with the reference option. It is a measure of the change in the key attribute that exactly offsets the difference in benefit or burden between the reference and the target options. The threshold can be a specific value or an interval within which the threshold lies. If the tradeoff exercise yields a specific value, then that threshold for each respondent for each trade-off exercise is known. If, however, the trade-off exercise results in a threshold interval, then the researcher has options for how to utilize these data. The researcher can simply report the threshold interval or the proportion of respondents choosing the target option at different threshold intervals. During recent year an increasing interest have been on cost-utility analyses, comparing the cost per quality-adjusted life-year (QALY) of different treatment regimes. However, most studies focus on biologic treatment. The incremental cost for subcutaneous compared to per oral methotrexate is not insignificant, still health economic evaluations comparing these two administration routes, and which administration to recommend, are scarce.
