NCT07655115 Arbaclofen Autism Spectrum Disorder Clinical Landscape Report 2026: Design, Endpoints, Sponsor and Readout Outlook
Turn a newly registered trial into a decision-ready clinical landscape. This report examines NCT07655115 using PatSnap Clinical Trials MCP for protocol design and endpoint evidence, with Drug & Asset MCP and Company & Deal Intelligence MCP used as the companion asset and sponsor enrichment workflow.

MCP evidence snapshot: 4 August 2026. Trial records, recruitment status and projected dates can change after the snapshot and should be rechecked before operational decisions.
Why NCT07655115 is a hot trial to watch
Autism Spectrum Disorder is being segmented by mechanism, treatment setting, geography and endpoint architecture. NCT07655115 is notable because it evaluates Arbaclofen in a Phase 3 design sponsored by Hospital General Universitario Gregorio Marañón. The main development question is whether the protocol can translate its rationale into a clinically interpretable and operationally credible readout.

Protocol design and endpoint interpretation
study with arbaclofen (4 weeks of titration and then 6 weeks of active/stable treatment). The effects of arbaclofen on target EEG and ERG metrics will be associated with the clinical response in measures of social and general function, adaptive behaviour, social anxiety, sensory behaviours, global functioning, and quality of life in Children and Adolescents with Autism Spectrum Disorders
Allocation is Randomized, masking is Quadruple, and the intervention model is Crossover Assignment. Planned enrollment of [object Object] participants across France, Spain 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.
- Change in power in the low frequency bands (theta/alpha) (between visits 1 and 2). (baseline to day 7) — To predict long term response to arbaclofen based on a single dose response during the placebo-controlled randomized single dose double blind stage.
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: Arbaclofen 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: Hospital General Universitario Gregorio Marañón is resolved to a normalized organization record in Spain. 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
NCT07655115 provides a focused lens on Autism Spectrum Disorder development. Its value will be determined by whether Arbaclofen can convert the current Phase 3 design into evidence that is clinically meaningful, operationally credible and differentiated from competing programs.
