Systemic sclerosis & Raynaud's

Circulating biomarkers in patients with systemic sclerosis–associated interstitial lung disease in the SENSCIS trial

Ann Rheum DisPublished Secondary analysis of the SENSCIS randomised trial

Authors' conclusion

Applying a dichotomised threshold for KL-6 can aid in identifying patients with SSc-ILD with more progressive ILD. Nintedanib reduced levels of the epithelial dysfunction marker, CA-125, and collagen synthesis epitope, pro-C6.

Study context

Population
Patients with SSc-ILD, ≤7 years since first non-Raynaud symptom, in the SENSCIS trial
Comparison
Nintedanib vs placebo; baseline biomarker levels and forced vital capacity (FVC) decline / modified Rodnan Skin Score (mRSS) change in the placebo group
Primary endpoint
Associations between baseline biomarker levels and decline in FVC over 52 weeks (placebo group)
Follow-up
52 weeks
Methodological detailsbiomarker analysis, mediation analysis
  • Biomarker analysis
  • Mediation analysis

Primary result

As reported in the abstract

Rate of decline in FVC (mL) by baseline KL-6

KL-6 >1000 U/mL

−132.5

estimate · 95% CI −174.1–-91.0 · mL

KL-6 ≤1000 U/mL

−56.4

estimate · 95% CI −95.2–-17.6 · mL

P = 0.009

Further findings

Change in mRSS at week 52 by baseline biomarkers

Higher baseline Pro-C3, CCL2 and CRP significantly associated with less improvement in mRSS (corrected for multiple comparisons)

Biomarker changes with nintedanib vs placebo · 52 weeks

Decreases in CA-125 and pro-C6 with nintedanib vs placebo

Mediation of nintedanib effect on FVC change at week 52 by CA-125 decrease at week 24

Proportion of effect attributed to treatment-related CA-125 decrease
48.0%
