Efficacy and Safety of Biosimilar AVT05 Versus Reference Product Golimumab in Combination with Methotrexate in Moderate-to-Severe Rheumatoid Arthritis: 52-Week Results of a Randomized, Parallel-Group, Double-Blind Study.
Trial report in BioDrugs : clinical immunotherapeutics, biopharmaceuticals and gene therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05842213 (Randomized, Double-blind, 2-arm Multicenter Study to Investigate the Efficacy, Safety and Immunogenicity Between Subcutaneous AVT05 and EU-approved Simponi® in Subjects with Moderate to Severe Rheumatoid Arthritis), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundGolimumab is a safe and effective treatment for patients with rheumatoid arthritis. Biosimilars to the reference product (RP; Simponi
objectivesThe aim of this study was to assess the efficacy of AVT05, a golimumab biosimilar, and RP, each used in combination with methotrexate, in participants with moderate-to-severe rheumatoid arthritis.
methodsThis was a 52-week, randomized, double-blind, two-arm, parallel-group, active-controlled study. Participants were randomized 1:1 to receive AVT05 (n = 251) or RP (n = 251), 50 mg subcutaneously once every 4 weeks to Week 12 inclusive. Randomization was stratified by the baseline Disease Activity Score-28 for Rheumatoid Arthritis using C-Reactive Protein (DAS28-CRP) [≤ 5.1 and > 5.1]. The primary endpoint was the change from baseline in DAS28-CRP at Week 16. At Week 16, responder participants (DAS28-CRP decreased by > 0.6 from baseline and disease activity DAS28-CRP ≤ 5.1) initially enrolled in the AVT05 arm continued to receive AVT05 every 4 weeks. Responder participants initially randomized to RP were re-randomized 1:1 to either continue receiving RP or switch to AVT05. Non-responders were discontinued from the study drug. Change from baseline in DAS28-CRP response criteria at weeks 4, 8, 12, 24, 32, 40, 48, and 52 and percentage of subjects achieving American College of Rheumatology 20/50/70 at weeks 4, 8, 12, 16, 24, 32, 40, 48, and 52 were assessed as secondary endpoints. Safety and immunogenicity endpoints were also assessed.
resultsAt Week 16, the least squares mean (standard error) change from baseline in DAS28-CRP in AVT05 and RP was - 2.89 (0.058) and - 2.98 (0.058), respectively. The two-sided 95% confidence interval of the least squares mean difference (0.09; standard error 0.082) was entirely contained within the prespecified equivalence margin of - 0.6, 0.6 (- 0.07, 0.25), supporting a demonstration of comparative efficacy. Two sensitivity analyses (one [S1] without exclusion of any data because of intercurrent events, and one [S2] excluding data following intercurrent events or relevant protocol deviations) supported the robustness of the primary endpoint estimates (S1 95% confidence interval - 0.07, 0.25; S2 95% confidence interval - 0.07, 0.25). There were no notable differences in subgroup analyses. Secondary efficacy analyses were consistent with the primary endpoint, including in participants who switched treatments. Overall safety profiles showed no clinically meaningful differences between treatments, including in participants who switched treatments. Immunogenicity profiles were comparable between treatment arms at all timepoints, including in participants who switched treatments.
conclusionsAnalysis of the change in DAS28-CRP from baseline to Week 16 supported the assessment of comparative efficacy between AVT05 and RP golimumab. Secondary efficacy endpoints were consistent with this, including in participants who switched. AVT05 had a safety and immunogenicity profile similar to that observed for RP at all timepoints, including in participants who switched treatments. CLINICAL
