What is the purpose of this trial?

Rheumatoid arthritis (RA) is a common disease with approximately 1% prevalence. RA is also a chronic, progressive disease with no cure. Current treatment goals are to minimize pain, limit joint damage, and prevent loss of function. Drugs used to treat RA include non-steroidal anti-inflammatory drugs (NSAIDS), glucocorticoids, and disease-modifying anti-rheumatic drugs (DMARDs), including biologics. Methotrexate (MTX) is the DMARD of choice in the treatment of RA, because it has been shown to be both well-tolerated and effective in achieving clinical response and slowing radiographic progression of disease. However, this drug alone results in remissions in only a small subset of patients and reliable predictors of DMARD response have yet to be identified. This study is open-label of 16-weeks duration to identify factors that help predict clinical responses to disease-modifying antirheumatic drugs (DMARD) therapies for rheumatoid arthritis (RA) participants. All participants will receive a starting dose of DMARD medication(s) which may be adjusted by the investigator as needed. If a participant becomes intolerant of a DMARD medication, the participant will be withdrawn at the discretion of the investigator. Necessary withdrawals prior to week 16 visits will be considered end of study. Otherwise, end of study data as well as study serum will be collected at week 16. A portion of the blood collected at baseline, week 8 and week 16 for the optional addendum portion of the study is for future research and will be utilized attempting to look to detect the generation of superoxide radicals. These radicals have been shown to be associated with inflammation and may correlate with the progression of RA, which if confirmed, should decrease the levels of these radicals signaling response to treatment.

Will I have to stop taking my current medications?

If you are already taking DMARDs, you must be on a stable dose for at least 6 weeks before starting the trial. If you are taking glucocorticoids, you need to be on a stable dose for at least 2 weeks.

Is there safety data for DMARDs like tofacitinib, baricitinib, tocilizumab, rituximab, and abatacept in humans?

Research shows that tofacitinib, baricitinib, tocilizumab, rituximab, and abatacept have been studied for safety in people with rheumatoid arthritis, and they are generally considered safe for human use, although individual responses can vary. ^{1 2 3 4 5}

What makes the DMARDs treatment for rheumatoid arthritis unique?

This treatment is unique because it includes a variety of drugs with different mechanisms of action, such as TNF inhibitors, T-cell co-stimulation modulators, and Janus kinase inhibitors, offering multiple options for patients who may not respond to traditional therapies. It combines both synthetic and biological DMARDs, providing a comprehensive approach to managing rheumatoid arthritis. ^{6 7 8 9 10}

What data supports the effectiveness of the drugs used in the DMARDs for Rheumatoid Arthritis trial?

Research shows that drugs like rituximab, abatacept, and tocilizumab are effective for rheumatoid arthritis, especially when other treatments have failed. These drugs work by targeting specific parts of the immune system to reduce inflammation and joint damage. ^{3 7 8 11 12}

In a study of 3162 adults with rheumatoid arthritis, rituximab and tocilizumab showed significantly longer durations of survival without treatment failure compared to abatacept, with average durations of 19.8 months and 19.1 months respectively, versus 15.6 months for abatacept.

No significant differences were found in safety outcomes, such as serious infections or cardiovascular events, indicating that while rituximab and tocilizumab may be more effective, they do not pose additional safety risks compared to abatacept.

A systematic review of ten clinical trials found that all biological treatments for rheumatoid arthritis, including adalimumab, etanercept, infliximab, abatacept, tocilizumab, golimumab, and certolizumab pegol, were more effective than placebo, indicating their overall efficacy in patients resistant to DMARDs.

Indirect comparisons showed that these biological drugs had similar efficacy based on the ACR50 response criteria, suggesting that their choice should be based on safety and convenience rather than effectiveness.

In a study of 6203 rheumatoid arthritis patients, those who switched from TNF inhibitors to alternative mechanisms of action (MOA) had higher treatment persistence rates (50.3%) compared to those who cycled within TNF inhibitors (45.2%).

Patients cycling between alternative MOA agents also showed improved persistence (51.4%) and significantly lower healthcare costs per persistent patient, suggesting that switching medication classes can be more effective and cost-efficient when initial therapies fail.

In a study of 196 rheumatoid arthritis patients who had previously failed TNFα blocker therapy, rituximab treatment resulted in a significantly greater reduction in disease activity compared to a second TNFα blocker, with a mean decrease in Disease Activity Score-28 of -1.64 versus -1.19.

Rituximab also led to a higher percentage of patients achieving a good response according to European League Against Rheumatism criteria (30% vs 15%) and fewer nonresponders (22% vs 35%), suggesting it may be a more effective option for these patients.

Tocilizumab is an effective treatment option for rheumatoid arthritis in patients who have not responded to other therapies, but it is not more effective than rituximab in cases of multiple treatment failures, based on clinical evaluations of four placebo-controlled trials.

While tocilizumab offers convenience with intravenous administration every four weeks, it carries significant risks of serious infections and other adverse effects, and its long-term safety profile, particularly regarding cancer risk, remains uncertain.

Tofacitinib 10 mg combined with methotrexate (MTX) and baricitinib 4 mg combined with MTX were found to be the most effective treatments for rheumatoid arthritis (RA) patients who did not respond adequately to previous therapies, based on a meta-analysis of 12 randomized controlled trials involving 5883 patients.

Both tofacitinib and baricitinib did not show a significant increase in the risk of serious adverse events compared to other treatments, indicating they are safe options for managing RA in these patients.

In a study involving 1681 patients with rheumatoid arthritis who had inadequate responses to previous treatments, tocilizumab showed rapid and sustained efficacy, with significant improvements in disease activity scores over 24 weeks.

The treatment was generally safe, with a low discontinuation rate of 5.1% due to adverse events, although patients who had recently used TNF inhibitors experienced a higher rate of adverse events compared to those who had never used them.

Tocilizumab showed significant improvement in joint symptoms for 10 out of 15 patients with systemic sclerosis (SSc) after 5 months, indicating its effectiveness for treating refractory polyarthritis.

Abatacept also improved joint parameters in patients after 11 months, but it did not show any benefit for muscle symptoms in SSc-myopathy, suggesting that while both treatments are safe, their efficacy may vary depending on the specific symptoms being treated.

In a study of 582 patients with rheumatoid arthritis who were positive for anti-cyclic citrullinated peptide (CCP+), abatacept and tofacitinib showed no significant difference in reducing disease activity after 6 months, indicating similar efficacy for both treatments.

Patients who had not previously used biologic therapies showed a slightly greater improvement in disease activity with abatacept compared to tofacitinib, but this difference was not statistically significant, suggesting that both medications are viable options for treatment.

Biologic agents are recommended for rheumatoid arthritis patients who do not respond well to traditional DMARDs, with anti-TNF agents being the most commonly used first-line biologic treatment.

Tocilizumab may be the most effective biologic when used alone, while rituximab is effective but not typically used first due to safety concerns.

Pharmacotherapy options in rheumatoid arthritis. Kumar, P., Banik, S.[2022]

The emergence of new therapeutics for rheumatoid arthritis, including kinase inhibitors and biosimilars, suggests a need for a revised classification system for disease-modifying antirheumatic drugs (DMARDs).

The proposed nomenclature divides DMARDs into two main categories: biological DMARDs (boDMARDs and bsDMARDs) and synthetic DMARDs (conventional csDMARDs and targeted tsDMARDs), which could enhance clarity in clinical studies and reviews.

Conventional disease-modifying antirheumatic drugs (DMARDs), like injectable gold, still show significant efficacy in treating rheumatoid arthritis (RA), with improvements in disease activity and X-ray progression comparable to modern biologics.

Despite the introduction of biologics, conventional DMARDs should be considered first-line treatments due to their effectiveness and lower cost, as they have demonstrated similar clinical benefits in trials, suggesting they are not outdated.
