Endothelin-1 receptor A antagonist rescue in male CD2AP mice

PRIMARY OUTCOME

partial rescue of vascular impairments in male mice only

EXPECTED OUTCOMES

1. The intervention targeting CD2AP shifts partial rescue of vascular impairments in male mice only in the predicted direction relative to the matched control arm. 2. Secondary disease-relevant readouts in Alzheimer's disease remain directionally concordant with the primary endpoint rather than showing isolated single-assay effects. 3. The effect persists after adjustment for baseline covariates, batch effects, or repeated-measures structure used in the study design.

SUCCESS CRITERIA

- Prespecified primary endpoint (partial rescue of vascular impairments in male mice only) improves versus control with p < 0.05 or an equivalent corrected threshold used by the study. - The effect size is biologically meaningful and reproduced across technical/biological replicates or the validation subset. - Safety, data quality, and missingness remain within protocol-defined bounds so the result is interpretable rather than driven by attrition or assay failure.

PROTOCOL

1. Establish male mice cohorts for Alzheimer's disease and predefine inclusion, exclusion, and quality-control criteria before intervention. 2. Apply the experimental manipulation described for CD2AP, alongside matched control or comparator arms, and document dose, exposure window, and sample timing in a locked protocol log. 3. Measure partial rescue of vascular impairments in male mice only together with orthogonal secondary readouts such as molecular, imaging, behavioral, or safety endpoints that are appropriate to the title and study design. 4. Use blinded outcome assessment where feasible, prespecified statistical analysis, and replicate the core readout across biological replicates or an independent validation subset. 5. Interpret results against the baseline study rationale: Pharmacological intervention study testing whether blocking endothelin-1 receptor A signaling can rescue vascular impairments in CD2AP mutant mice, with sex-specific analysis.
