RESUMO
The SENSCIS trial of nintedanib versus placebo is the largest trial conducted to date in patients with systemic sclerosis-associated interstitial lung disease (SSc-ILD). This trial enrolled 576 patients with an extent of fibrotic ILD on high-resolution computed tomography of >10%. Median time since first non-Raynaud symptom was 3.4 years. Almost half of the patients were receiving a stable dose of mycophenolate at baseline. Key findings of the trial included that at baseline, despite having significant lung fibrosis on HRCT and impairment in lung function, 20% of the patients did not have cough and 30% did not have dyspnoea. Over 52 weeks, a marked decline in forced vital capacity (FVC) was observed (-112.0 mL/year in patients with diffuse cutaneous SSc [dcSSc] and -74.5 mL/year in patients with limited cutaneous SSc [lcSSc] in the placebo group). Loss of FVC was associated with an increased risk of SSc-related hospitalisation or death. Although certain subgroups of patients were at higher risk of progression, it was not possible to make a robust prediction of FVC decline based on baseline characteristics. The relative effect of nintedanib versus placebo on reducing the rate of FVC decline was consistent across subgroups based on factors including anti-topoisomerase I antibody (ATA) status, dcSSc vs. lcSSc, and use of mycophenolate at baseline. The side-effects of nintedanib were mainly gastrointestinal events, particularly diarrhoea. Nintedanib did not have a significant effect on skin fibrosis or health-related quality of life. Overall, the results of the SENSCIS trial support the importance of prompt identification and treatment of SSc-ILD and the consideration of nintedanib as a treatment option.

BACKGROUND: The molecular signature response classifier (MSRC) is a blood-based precision medicine test that predicts nonresponders to tumor necrosis factor-É inhibitors (TNFi) in rheumatoid arthritis (RA) so that patients with a molecular signature of non-response to TNFi can be directed to a treatment with an alternative mechanism of action. RESEARCH DESIGN AND METHODS: This study evaluated decision choice and treatment outcomes resulting from MSRC-informed treatment selection within a real-world cohort. RESULTS: Therapy selection by providers was informed by MSRC results for 73.5% (277/377) of patients. When MSRC results were not incorporated into decision-making, 62.0% (62/100) of providers reported deviating from test recommendations due to insurance-related restrictions. The 24-week ACR50 responses in patients prescribed a therapy in alignment with MSRC results were 39.6%. Patients with a molecular signature of non-response had significantly improved responses to non-TNFi therapies compared with TNFi therapies (ACR50 34.8% vs 10.3%, p-value = 0.05). This indicates that predicted non-responders to TNFi therapies are not nonresponders to other classes of RA targeted therapy. Significant changes were also observed for CDAI, ACR20, ACR70, and for responses at 12 weeks. CONCLUSIONS: Adoption of the MSRC into patient care could fundamentally shift treatment paradigms in RA, resulting in substantial improvements in real-world treatment outcomes.
