Abstract

OBJECTIVES:
Targeted drugs against key pathogenetic molecules such as TNF-alpha have significantly improved outcomes in rheumatoid arthritis (RA). They are widely used in clinical practice and drug registries give us information to support their use. Adalimumab (ADA) is able to induce a comprehensive disease control in RA by achieving clinical, functional and radiographic control.
METHODS:
By interrogating 2 Italian registries, LORHEN and GISEA, we analysed the efficacy of ADA in first- or second-line in a total of 2262 RA patients.
RESULTS:
Patients in 1st line were significantly older, with lower disease activity and HAQ scores compared to 2nd line. In 1st line, rates of DAS28-remission (DAS28rem) at 2 years were 34.4% while 26.5% in 2nd line (p=0.038). A normal HAQ score (HAQ≤0.5) was achieved in 53.5% after 2 years in 1st line versus 30.1% in 2nd (p<0.0001). DAS28rem+HAQ≤0.5, a combined parameter that we defined global clinical disease control, was reached in 20.7% in 1st line versus 13.3% in 2nd (p<0.01). Five-year-survival on therapy was higher for patients in 1st line (45.6% vs. 33.2%, p<0.0001). Discontinuation due to lack of efficacy was lower in 1st line (37.4 vs. 54.4%, p<0.0001). Rates of adverse events were similar.
CONCLUSIONS:
Responses in 1st line are generally significantly better than after a first anti-TNF-alpha failure but patients in 2nd line have a worse clinical and functional profile. A global disease control with clinical and functional remission is an achievable target in both lines.
