Study Overview
This study looked at two important ways to measure how well treatments work for patients with systemic lupus erythematosus (SLE). These methods are called BICLA and SRI4. We wanted to see how often these methods agreed or disagreed when looking at patients who received standard care or a placebo in two clinical trials: EXPLORER and ATHOS.
Methods Used
We analyzed data from patients who received a placebo in both trials. We measured disease activity using different scoring systems. We then categorized patients as responders or non-responders based on BICLA and SRI4 results.
Key Findings
In the EXPLORER trial, fewer patients showed a positive response using BICLA compared to SRI4 (29.9% vs 41.4%). In contrast, the ATHOS trial showed similar response rates (41.2% for BICLA and 43.8% for SRI4). Overall, there was a moderate level of agreement between the two methods.
Understanding Discordance
In both trials, some patients had different results between BICLA and SRI4. For example, in EXPLORER, 6.9% of patients had a positive BICLA response but a negative SRI4 response. The presence of arthritis and rash significantly influenced these differences.
Practical Implications
These findings suggest that using both BICLA and SRI4 can provide a more complete picture of treatment effectiveness for SLE. It highlights the need for multiple measures to assess patient responses rather than relying on just one.
Opportunities for Improvement
Clinics can set clear goals for evaluating treatment effectiveness by using both BICLA and SRI4. This can help in understanding patient responses better and tailoring treatments accordingly.
Next Steps
To implement these findings, clinics can start with small pilot projects to track how well these measures work in real-world settings. Using AI tools tailored to specific clinical needs can assist in analyzing and improving patient care.
