Clinical Trial Statistical Analysis Plan (SAP) Development & Validation
Generate FDA-compliant Statistical Analysis Plans for clinical trials automatically
What You Can Do
You can automate the creation of comprehensive, regulatory-compliant Statistical Analysis Plans (SAPs) for clinical trials. The skill generates complete SAP documents with FDA/ICH-aligned sections, performs compliance validation, optimizes statistical methodologies, and ensures consistency with trial protocols—reducing SAP development time from weeks to days.
Features
Generate complete SAP structure with all FDA/ICH-required sections including objectives, endpoints, analysis populations, statistical methods, missing data handling, and interim analysis plans.
Built-in validation against FDA, EMA, and ICH-GCP guidelines ensures your SAP meets all current regulatory requirements and documentation standards.
Recommend appropriate statistical methods based on trial design, endpoint types, and regulatory precedent, including detailed justifications for method selection.
Cross-reference SAP against study protocol to verify alignment on study design, populations, endpoints, and statistical approaches—flagging any discrepancies.
Calculate and document statistical power, effect sizes, and sample size rationale with detailed assumptions and sensitivity analysis.
Generate precise, regulatory-ready definitions for Intent-to-Treat (ITT), Per-Protocol (PP), and safety analysis populations with inclusion/exclusion logic.
Export SAS or R analysis scripts that implement your SAP specifications, formatted for regulatory submissions and ready for quality control.
Example Output
Example SAP Section Generated:
2.3 Analysis Populations
Intent-to-Treat (ITT) Population: All randomized subjects who received at least one dose of study drug, analyzed according to randomized treatment assignment regardless of protocol adherence or completion status.
Per-Protocol (PP) Population: Randomized subjects who completed the trial per protocol without major protocol deviations affecting the primary endpoint, analyzed according to treatment received.
4.2 Primary Efficacy Analysis
Primary Endpoint: Change from baseline in HbA1c at Week 24
Statistical Method: Analysis of Covariance (ANCOVA) with treatment and region as fixed effects, baseline HbA1c as covariate. Two-sided significance level α=0.05.
Justification: ANCOVA is standard for chronic disease endpoints with baseline measurement and improves precision by adjusting for baseline variation. Stratification by region accounts for geographic variation in HbA1c response.
Sample Size Justification: N=450 (225/arm) provides 90% power to detect 0.4% HbA1c difference (clinically meaningful) with estimated SD=1.2% and Type I error α=0.05.
