Subcutaneous Ocrelizumab for the Treatment of Relapsing Forms of Multiple Sclerosis: A Budget Impact Model.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThe aim of this study was to evaluate the budget impact of introducing the subcutaneous (SC) form of ocrelizumab for patients with relapsing forms of multiple sclerosis (RMS) with high disease activity (HA) despite previous treatment or with rapidly evolving severe (RES) disease in Italy from the hospital perspective.
methodsA 3-year dynamic budget impact model with a Markov structure was developed de novo to simulate patient transitions across Expanded Disability Status Scale-defined health states. The current scenario (without ocrelizumab SC) was compared with an alternative scenario reflecting expected ocrelizumab SC uptake. Number of eligible patients reflected Italian population and projected market shares. Efficacy inputs were obtained from published literature, with adherence and persistence sourced from Italian real-world data. Unit costs-including drug administration, monitoring, adverse events, disease management, and relapse-were collected from Italian sources. Drug acquisition costs were considered in a scenario analysis. Parameter uncertainty was explored through deterministic sensitivity and scenario analyses.
resultsOver 3 years, 22,128 patients were eligible, of whom 5389 were assumed to receive ocrelizumab SC. Ocrelizumab SC introduction would generate cumulative savings of about €2.0 million, mainly from reduced administration and monitoring costs, with additional savings from relapse and disease management expenditures. When drug acquisition costs were included, total savings rose to roughly €7.1 million. Sensitivity analyses confirmed the robustness of these findings.
conclusionsOcrelizumab SC may be a cost-saving and resource-efficient option for HA/RES RMS management in Italy. By reducing administration time while maintaining the established clinical profile of the intravenous (IV) formulation of ocrelizumab, its adoption can enhance hospital efficiency and deliver meaningful budgetary savings.
