Phase 1, randomized trials of MEDI1341: cerebrospinal fluid free α-synuclein lowered by >50.
Trial report in Brain communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03272165 (A Randomized, Double-blind, Placebo-controlled Study of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of Single Ascending Doses of MEDI1341 in Healthy Male and Female Volunteers), which is not on this map. Cited by 5 papers.
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.

Abstract
Accumulation of pathological forms of α-synuclein is a hallmark of Parkinson's disease. MEDI1341 (also known as TAK-341) is a high-affinity, α-synuclein-specific, fully human monoclonal antibody that binds the C-terminal region of human α-synuclein. Pre-clinical studies of MEDI1341 demonstrated significant reductions in α-synuclein accumulation and propagation along axons. Two randomized, double-blind, placebo-controlled, Phase 1 studies administering MEDI1341 intravenously were conducted; a single ascending dose study (NCT03272165) of MEDI1341 (70, 210, 400, 1200, 2400 or 4500 mg;
