Title: Rheumatoid Arthritis-Small Molecules, Biologics and Gene Therapy V: Immunogenecity
Session Type: ACR Concurrent Abstract Session
Session Time: 2:30PM-4:00PM
Background/Purpose:
As many as one third of patients show insufficient response to their first TNF inhibitor (TNF-insufficient response, TNF-IR). The lack of efficacy of one anti-TNF drug does not preclude the potential efficacy of another anti-TNF drug. Alternatively, switching to a non-TNF-targeted therapy is also a rationale strategy. These 2 strategies (a second anti-TNF agent or a non-TNF targeted therapy) have only been compared in scarce observational studies in TNF-IR patients. However, no randomized controlled trial has compared the efficacy of a non-TNF-targeted biologic and a second anti-TNF drug in TNF-IR patients. We previously presented the preliminary results at 6 months. We now present the final 12 month-results of the trial.
Methods:
The “Rotation of anti-TNF Or Change of class of biologic” (ROC) trial (NCT01000441) is a multicenter,investigator-initiated, open, parallel-group, randomized controlled trial. Patients with inadequate response to a first anti-TNF were randomly assigned in a 1:1 ratio to receive a non-TNF-targeted biologic or a second anti-TNF agent. The choice of the biologic prescribed within each randomized group (ie, non-TNF-targeted biologic or a second anti-TNF agent) was left to the treating clinician. The study duration was 48 weeks.
Results:
-
Week 12
At week 12 (W12), for patients randomized to a non-TNF-targeted biologic (n=146) or a second anti-TNF agent (n=146), 64.2% and 47.8%, respectively, achieved a good or moderate EULAR response (good response: 27.7% and 13.2%, respectively; moderate response: 36.5% and 34.6%, respectively) (OR 2.01, 95% CI [1.23; 3.32], p = 0.005).
-
Week 24
At W24 (primary outcome), 69.7% and 52.1%, respectively, achieved a good or moderate EULAR response (good response: 39.4% and 21.1%, respectively; moderate response: 30.3% and 31.0%) (OR 2.12, 95%confidence interval [95% CI] [1.31; 3.46], p=0.003). At W24, DAS28-ESR was lower for patients with the non-TNF-targeted biologic than second anti-TNF drug (difference adjusted to baseline value -0.43, 95% CI [-0.72; ‑0.14], p= 0.004). The proportion with low disease activity was 44.6% and 27.9%, respectively (OR 2.09, 95%CI [1.27; 3.43], p= 0.004).
-
Week 48
At W48, 60.0% of patients treated with a non TNF-targeted biologic and 43.2% of those treated with a second anti-TNF were EULAR responders (good response: 37.7% and 21.2%, respectively; moderate response: 22.3 and 22.0%, respectively) (OR 1.97 (95%CI [1.21; 3.24], p = 0.007). DAS28-ESR was lower for patients with the non-TNF-targeted biologic than second anti-TNF drug (difference adjusted to baseline value -0.38, 95% CI [-0.69; ‑0.08], p= 0.013). The proportion with low disease activity was 40.8% and 23.5%, respectively (OR 2.24, 95%CI [1.32; 3.82], p= 0.003). The proportion with DAS28-ESR remission was 26.9% and 13.6%, respectively (OR 2.34, 95% CI [1.24; 4.39], p= 0.009. Ongoing comparison of radiographic progression and safety will be also presented at ACR.
Conclusion: This randomized controlled trial demonstrated a better efficacy of a non-TNF-targeted biologic than a second anti-TNF agent for TNF-IR patients. This superiority was consistent over time and across numerous outcome criteria.
