AZP2006 in Progressive Supranuclear Palsy: Outcomes from a Phase 2a Multicenter, Randomized Trial, and Open-Label Extension on Safety, Biomarkers, and Disease Progression.

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 was to evaluate the safety, tolerability, pharmacokinetics, and potential clinical efficacy of AZP2006, an oral pleiotropic drug modulating progranulin levels, in patients with progressive supranuclear palsy (PSP), a rare tauopathy.
methodsA randomized, double-blind, placebo-controlled, parallel-group trial was conducted at three sites in France. Eligible participants (age 40-80 years, diagnosed with probable or possible PSP) were randomized to receive AZP2006 (60 mg once per day [QD] or 80/50 mg QD [80 mg for 10 days followed by 50 mg]) or placebo for 12 weeks. Assessments included safety, pharmacokinetics (plasma and whole blood), pharmacodynamics (cerebrospinal fluid and plasma biomarkers), and exploratory clinical efficacy (PSP rating scale, clinical global impression, and activities of daily living). Approximately 2 years post-trial, an open-label extension (OLE) enrolled 15 patients who received active treatment (AZP2006) for 6 months.
resultsForty-one patients were screened, 36 randomized, and 34 completed the study. AZP2006 demonstrated acceptable tolerability and safety with no treatment-related serious adverse events. Pharmacokinetic analysis confirmed rapid absorption, a long half-life (60 mg: 764.3 hours; 80/50 mg: 684.7 hours), and steady-state by day 45 (60 mg) and day 28 (80/50 mg). Biomarker analyses indicated blood-brain barrier crossing, target engagement, and stabilized progranulin levels. Trends in efficacy favored slower disease progression in AZP2006 groups. The OLE demonstrated a slowed progression of the disease and revealed no notable safety concerns.
conclusionsAZP2006 was well-tolerated and demonstrated favorable trends in biomarker and clinical outcomes. These preliminary signals support further investigation to determine whether a meaningful clinical benefit can be achieved in PSP with AZP2006. © 2025 The Author(s).
