Five Years of Ublituximab in Multiple Sclerosis: ULTIMATE I and II Open-Label Extension Study.
Trial report in JAMA neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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
Importance: In the 2-year Study to Assess the Efficacy and Safety of Ublituximab in Participants With Relapsing Forms of Multiple Sclerosis (ULTIMATE) I and II randomized clinical studies, disease activity was significantly reduced with ublituximab vs teriflunomide in participants with relapsing multiple sclerosis (RMS). Objective: To evaluate long-term ublituximab clinical efficacy and safety. Design, Setting, and Participants: The 2-year, multicenter, randomized, active-controlled, double-blind period (DBP) of the ULTIMATE I and II phase 3 studies occurred September 2017 to November 2020. Enrollment in the ongoing ULTIMATE open-label extension (OLE) study began November 2019; data cutoff for this analysis was January 1, 2024. Intervention: ULTIMATE OLE participants continued ublituximab (UBL-UBL) or switched from teriflunomide to ublituximab (TER-UBL). Main Outcomes and Measures: Efficacy (annualized relapse rate [ARR], 24-week confirmed disability progression [CDP24], and 24-week confirmed disability improvement [CDI24]) and safety were key outcomes. Results: Of 985 adults with RMS who completed ULTIMATE I and II, 851 enrolled in the ULTIMATE OLE and were included in the analysis. On DBP completion, more than 85% of participants (UBL-UBL, 422 of 494; TER-UBL, 429 of 491) entered the OLE, of whom more than 70% (UBL-UBL, 297 of 422; TER-UBL, 327 of 429) continued taking ublituximab at year 5 (OLE year 3) at data cutoff, making up the analysis population (mean [SD] age, 38.5 [9.7] years; 532 female [62.5%]). TER-UBL participants experienced a 58.4% ARR reduction at 1 year after the switch (0.182 vs 0.076; rate ratio, 0.42; 95% CI, 0.29-0.60; P < .001), and ARR continued to decrease to 0.048 (year 4) and 0.045 (year 5). UBL-UBL participants had further ARR reductions after the DBP (0.053, 0.032, and 0.020 for years 3, 4, and 5, respectively). At year 5, CDP24 was 8.0% in UBL-UBL participants vs 14.3% in TER-UBL participants (P = .01), and CDI24 was 17.0% in UBL-UBL participants vs 12.2% in TER-UBL participants (P = .02). Adverse events were consistent with the established safety profile from pivotal trials, with exposure-adjusted incidence rates per 100 participant-years of serious infections (excluding COVID events) of 2.10 (UBL-UBL) and 2.58 (TER-UBL). On average, immunoglobulin levels remained above the lower limit of normal, and no significant differences in serious infection rates were observed regardless of immunoglobulin level. Conclusions and Relevance: Results reveal that sustained clinical benefits were observed with 5 years of ublituximab treatment: ARR in year 5 showed 1 relapse per 50 participant-years of ublituximab treatment and 92% of UBL-UBL participants remained free from CDP24. Results confirm long-term ublituximab benefits and early initiation of high-efficacy treatment. Trial Registration: ClinicalTrials.gov Identifier: NCT04130997.
