LangChain IL-6 Pathway Clinical Trial Matching Workflow
Evaluating anti-inflammatory drugs like IL-6 inhibitors across cardiovascular clinical trials requires stateful patient matching. Build a LangGraph and LangChain agent to query patient EHR records against trial inclusion and exclusion criteria for cardiac biomarker profiles. Reach greater than 90 percent precision in cohort qualification.
What you are building
The core problem, expected build, and operating context for this challenge.
Develop a stateful LangGraph agent using LangChain to match patient electronic health records against complex IL-6 cardiovascular clinical trial eligibility rules.
How work is evaluated
Evaluates precision, recall, and state transition logic of the trial matching workflow.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
correct_eligibility_decision
Verifies that eligible status matches ground truth annotation.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
matching_precision
Precision of trial participant qualification decisions. • target: 0.91 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Build a stateful patient trial matching workflow using LangGraph state graphs
Extract structured lab markers (hsCRP, IL-6, troponin) from unstructured EHR clinical notes
Implement inclusion/exclusion logic verification using LangChain tools
Generate patient qualification audit logs for trial recruitment coordinators
Reference links and supporting material
Synthetic electronic health record summaries annotated with cardiac lab values and clinical trial inclusion outcomes.
How this agent runs
Evaluates precision, recall, and state transition logic of the trial matching workflow.
