Clinical Trials

Neurology expert witnesses with clinical trial experience can be particularly relevant when a trial involves neurological or neurodegenerative conditions and the dispute requires both trial-methodology knowledge and neurological context. Disease-specific expertise may be important when interpreting participant criteria, neurological examinations, cognitive or functional outcome measures, imaging findings, biomarkers, treatment effects, or adverse events. The required background should match the neurological condition and the particular trial questions at issue.

An appropriately qualified Clinical Trials Expert Witness can examine how primary and secondary endpoints were defined, measured, timed, and documented and whether their treatment in the study record was consistent with the protocol and, where applicable, the statistical analysis plan. Questions may involve the timing and rationale for changes to endpoints, missing assessments, measurement methods, or whether the reported conclusions accurately reflect the prespecified outcomes and analyses. More complex disputes involving statistical inference or multiplicity may also call for separate biostatistical expertise.

A separate Biostatistics expert may be appropriate when the dispute turns on specialized statistical aspects of trial design, analysis, or interpretation. Examples include sample-size calculations, statistical power, model selection, handling of missing data, interim analyses, multiplicity, confidence intervals, or interpretation of statistical significance. Clinical-trial and biostatistical expertise can address overlapping but distinct aspects of the same evidentiary record, depending on the technical questions and the qualifications of the experts involved.
