ML-Enhanced Response-Adaptive Randomization Planner
Uses biomarker and outcomes data to support adaptive allocation simulations before protocol lock Evidence basis: JAMIA Open simulations showed ML-based response-adaptive randomization can assign more participants to better-performing options; FDA adaptive-design guidance supports such methods when pre-specified and statistically controlled
The Problem
“ML-Enhanced Response-Adaptive Randomization Planner”
Organizations face these key challenges:
Uses biomarker and outcomes data to support adaptive allocation simulations before protocol lock
Impact When Solved
The Shift
Human Does
- •Review biomarker and outcomes data manually before protocol lock
- •Coordinate randomization planning through spreadsheets and document exchanges
- •Assess allocation options and trial tradeoffs through expert discussion
- •Perform retrospective quality checks on planning assumptions
Automation
- •No AI-driven simulation support in the legacy workflow
- •No automated prioritization of promising allocation scenarios
- •No continuous monitoring of planning inputs for emerging signals
Human Does
- •Approve adaptive randomization assumptions and protocol-ready planning choices
- •Review AI-prioritized scenarios and decide which options move forward
- •Handle exceptions, conflicting evidence, and edge-case trial considerations
AI Handles
- •Analyze biomarker and outcomes data to generate adaptive allocation scenarios
- •Prioritize response-adaptive randomization options based on simulated performance
- •Surface high-impact risks and opportunities earlier in the planning process
- •Produce consistent planning artifacts to support protocol lock decisions
Operating Intelligence
How ML-Enhanced Response-Adaptive Randomization Planner runs once it is live
AI runs the first three steps autonomously.
Humans own every decision.
The system gets smarter each cycle.
Who is in control at each step
Each column marks the operating owner for that step. AI-led actions sit above the divider, human decisions and feedback loops sit below it.

Human lead
Approval, override, feedback
AI handles assembly, analysis, and execution. The human gate sits at the decision point. Every cycle refines future recommendations.
The Loop
6 steps
Assemble Context
Combine the relevant records, signals, and constraints.
Analyze
Evaluate options, risk, and likely outcomes.
Recommend
Present a ranked recommendation with supporting rationale.
Human Decision
A human accepts, edits, or rejects the recommendation.
Authority gates · 1
The system must not finalize adaptive randomization assumptions or protocol-ready planning choices without review and approval from the clinical trial statistician and study team [S1].
Why this step is human
The decision carries real-world consequences that require professional judgment and accountability.
Execute
Carry out the approved action in the operating workflow.
Feedback
Outcome data improves future recommendations.
