Updated over 2 weeks ago

Protocol SmartDesign ​leverages AI to recommend optimal primary endpoints and inclusion/exclusion criteria associated with the highest chance of operational success in clinical research, streamlining the protocol planning process, reducing complexities and saving time required for protocol design.​

The AI model analyzes Norstella proprietary historical data, real-world data and sources from the public domain to make protocol recommendations, increasing the likelihood of successful outcomes and reducing the risk of protocol design errors.​

Successful Trials:

“Successful trials” is defined as hitting a completion date within +/- 60 days of the initial anticipated completion date. These are the trials that feed the model and inform the recommendations generated by the application. The total number of successful trials for your study will appear in the banner of the main page.

Primary endpoints:

The model’s recommendations for primary endpoints are derived from an analysis of historically successful trials that match the selected study criteria. By examining these trials, the model identifies patterns and trends that are associated with higher success rates and fewer amendments. This analysis helps in determining which primary endpoints are most likely to contribute to the success of the study, based on empirical evidence from similar trials. The goal is to provide recommendations that optimize the likelihood of achieving positive outcomes and minimize the need for modifications during the trial.

Inclusion criteria:

The model’s recommendations for inclusion criteria are informed by analyzing a dataset of historically successful trials relevant to the selected study parameters. It examines these trials to identify criteria that are associated with higher success rates and minimal need for changes.

Exclusion criteria:

The model’s recommendations for exclusion criteria are based on an analysis of historical data from successful trials that align with the selected study parameters. By evaluating these trials, the model identifies exclusion criteria that are linked to improved success rates and reduced need for modifications. This ensures that the recommended criteria are both effective and practical, drawing from proven practices in similar studies.

Model Trial List Summary Tiles:

Mean (average) number of Sites:

The historical average number of sites used in similar trials conducted over the past five years is calculated based on the user-selected Therapeutic Area (TA), disease, patient segment, and trial phase. If no exact match is found for the selected criteria, values are derived using data from the selected disease only. Minimum, median, and maximum values are also provided to give users a clear view of the historical range within the selected indication.

Mean (average) number of Participants:

The historical average number of participants reflects the mean count of participants in similar trials conducted over the past five years, based on the user-selected Therapeutic Area (TA), disease, patient segment, and trial phase. If no exact match is found for the selected criteria, values are derived using data from the selected disease only. Minimum, median, and maximum values are also provided to give users a clear view of the historical range within the selected indication.

Enrollment Rate Based On Completed Trials (Pt/Site/Month):

The Completed Trials Enrollment Rate reflects the mean (average) enrollment rate observed in comparable clinical trials conducted globally over the past five years. Minimum, median, and maximum values are also provided to give users a clear view of historical trial performance within the selected indications.

This metric is derived from the user-selected Therapeutic Area (TA), disease, patient segment, and trial phase, and is calculated without applying country-specific constraints, ensuring a broad, international perspective. If the PSD model expands the patient segment or trial phase, this benchmark adjusts accordingly to maintain a fair and consistent comparison with the forecasted results.

It serves as a benchmark for evaluating forecasted enrollment rates against historical performance.

Forecasted Enrollment Rate (Pt/Site/Month):

It represents the predicted enrollment rate for the study based on the entered criteria, utilizing data from similar trials to forecast trends. The forecasted rate will dynamically adjust in response to any changes made to the Primary Endpoints (PE) and Inclusion and Exclusion (I&E) recommendations, ensuring the prediction reflects the most accurate and current study parameters.
