MCP evidence snapshot: 13 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.

Why NCT07518810 is a hot trial to watch

Multiple System Atrophy is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07518810 is notable because it evaluates Butylphthalide in a Phase 2/3 design sponsored by The Second Affiliated Hospital Zhejiang University. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

Trial landscape snapshot

Protocol design and endpoint interpretation

The present study aims to conduct a randomized controlled trial to evaluate the efficacy and safety of 3-n-Butylphthalide (NBP) in improving symptoms in patients with Multiple System Atrophy (MSA). The main questions it aims to answer are: 1. To evaluate whether NBP soft capsules, compared with placebo, alleviates the major clinical symptoms in patients with MSA. 2. Whether NBP application is safe to treat patients with MSA. In this trial, NBP will be compared with placebo (similar soft capsule without effective component of NBP) to demonstrate if NBP can alleviates MSA symptoms Participants of ENMSA will: 1. Take NBP or Placebo three times a day for 6 months 2. Be served with clinical visit four times for follow-up and tests 3. Keep a diary of drug application and symptom changes

Allocation is Randomized, masking is Quadruple, and the intervention model is Parallel Assignment. Planned enrollment of [object Object] participants across China shapes statistical precision, execution risk and external validity. Interpretation should account for baseline risk, prior therapy, assessment schedule, missing-data handling and clinical relevance—not only statistical significance.

• Main symptom control of MSA (Baseline; 1st, 3rd, 6th, 12th month after intervention initiation) — Use sum score Movement Disorder Society-Unified Multiple System Atrophy Rating Scale(MDS-UMSARS; score range: 0-104; higher score means worse symptoms of MSA) part I+II to evaluate the effectiveness of main symptom control of MSA

Readout outlook and evidence gap

The current protocol points to [object Object] as the best available readout proxy. Because this is an active or newly posted study, a trial-specific result citation is not included until a normalized clinical-trial-result record becomes available. That gap is itself operationally important: teams should monitor first result indexing, conference abstracts, protocol amendments and changes to the primary-completion date.

Asset and sponsor context

Drug & Asset MCP profile: Butylphthalide is indexed as No normalized modality returned, with target No normalized target returned, mechanism No normalized mechanism returned, and global highest development status No normalized global status returned.

Company & Deal Intelligence MCP profile: The Second Affiliated Hospital Zhejiang University is resolved to a normalized organization record in Hangzhou, China. The organization workflow adds identity, location, portfolio and partnering context where available.

The sponsor profile matters because scientific rationale alone does not determine development value. Manufacturing readiness, portfolio fit, geographic reach, partnering capacity and the ability to fund confirmatory development can determine whether a positive signal becomes a competitive asset.

White space around this program

• Sharper patient selection: prospective biomarker or phenotype definitions that identify who is most likely to benefit.
• Clinically interpretable endpoints: outcomes connecting activity with function, symptoms, survival or treatment burden.
• Comparator relevance: evidence against the most decision-relevant contemporary standard of care.
• Broader external validity: evidence across additional geographies, demographic groups and real-world settings.
• Operational differentiation: a development path that closes the readout gap without sacrificing safety or durability.

What to monitor next

Monitor recruitment, enrollment changes, protocol amendments, endpoint hierarchy, primary-completion timing, first result indexing, asset ownership and sponsor partnerships. A change in endpoint, population or ownership can alter the probability of success before a headline data release.

Bottom line

NCT07518810 provides a focused lens on Multiple System Atrophy development. Its value will be determined by whether Butylphthalide can convert the current Phase 2/3 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
