Ramp up your Patient Recruitment with the right selection Through our Automated Clinical Trial Matching solution.

Powered by NLP.


As a Lifesciences company your starting point for clinical trials is often your biggest bottleneck – clinical trial recruitment (patient recruitment) of eligible patients is crucial. Our Automated Clinical Trial Matching solution helps automate this manual and time-consuming patient recruitment task using leading-edge technologies – Natural Language Processing (NLP) and Machine Learning (ML) techniques. It extracts key information from a series of narrative clinical documents of the patients and collates helpful evidence. So you are empowered to make informed decisions on patient eligibility according to the defined inclusion and exclusion criteria.

The accuracy of matching is vital, and we accomplish this by continuous training of the machine with the right medical ontologies. Domain experts – working closely with our development team throughout the lifecycle – annotate and curate the data to aid in the correct interpretation and better accuracy of our matching.

In sum, our solution automates the current manual approach, removes people dependency (for analysis and insights) and brings in the specialization and sophistication needed. Incorrect matching and delays are a thing of the past.

ACTM @ Work

Circlebase: ACTM

The solution extracts information from the patient data which resides in multiple formats (pdf, scanned patient report, other medical data format ex. DICOM). It then identifies the correct entities (diseases, drug, dosage) and the corresponding value, and maps it as per medical coding standards.

Circlebase ACTM Match Score

Match score is determined based on the defined inclusion and exclusion criteria for the study. Patient data from multiple formats are curated as per the ontology and our AI model determines the match score based on the defined weightage. The detailed report for the match score is also available.

Patient Cohort Builder The entity extraction app identifies a wide range of clinical, social, and demographic entities from the data, which could then be used to identify the suitable patient cohorts for recruitment drives.

Lanny Turner MD Chief Medical Officer, Circlebase
“As a Principal Investigator, I learned that the greatest inefficiency in clinical trials is that of trying to identify patients who are eligible for a study. The Circlebase solution, ACTM (Automated Clinical Trial Matching), greatly reduces both the expense and time required to identify the patient cohort for any study type.”
Dr. Lanny Turner, CMO – Circlebase
