Abstract

fetched live from OpenAlex

Introduction The pivotal phase 3 ADVANCE study evaluated the efficacy of subcutaneous peginterferon beta-1a 125 mcg every 2 weeks in RRMS patients, approximately 45% of whom were newly diagnosed and had no prior disease-modifying therapy (DMT) use. We evaluated peginterferon beta-1a’s effect on clinical and radiological disease activity in newly diagnosed, treatment-naive patients from ADVANCE. Methods ADVANCE was a 2 year double-blinded study. In year 1, patients were randomised to receive peginterferon beta-1a every 2 or 4 weeks or placebo. In year 2, placebo patients were re-randomised to receive peginterferon beta-1a every 2 or 4 weeks (delayed-treatment group). Here, the subgroup of patients diagnosed ≤1 year prior to enrolment who had no prior DMT use was analysed. Annualised relapse rate (ARR), time to first relapse, 24 week confirmed disability worsening (CDW), MRI endpoints, and safety were compared between the every-2-weeks group and the delayed-treatment group. Results Over 2 years, the adjusted ARR in newly diagnosed patients was 32.3% lower for the peginterferon beta-1a every-2-weeks group (n=231) than for the delayed-treatment group (n=229; p=0.0352). Time to first relapse was longer in the every-2-weeks group than in the delayed-treatment group (p=0.0101), and the rate of 24 week CDW was numerically lower in the every-2-weeks group than in the delayed-treatment group. At year 2, the number of new/newly-enhancing T2 lesions was lower in the every-2-weeks than in the delayed-treatment group (p<0.0001), although no difference in the number of gadolinium-enhancing lesions was observed. The safety profile in newly diagnosed patients was similar to that of the overall patient population. Conclusion Newly diagnosed, treatment-naive patients had significantly reduced disease activity when administered peginterferon beta-1a every 2 weeks compared with delayed-treatment patients. These results are generally consistent with results from the ADVANCE overall population and highlight the benefits of initiating therapy early in the RRMS disease course. Study support Biogen

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
