Safety review in days, not weeks

The challenge

The sponsor ran a portfolio of trials in a serious disease area, where the safety profile of a candidate matters enormously. Safety data was reviewed once a month. A team worked through more than a thousand adverse events by hand, comparing the current cycle against earlier ones and looking for anything that stood out.

The process worked, but it was slow. By the time a possible signal was confirmed, three weeks could have passed since the underlying events were recorded. In a safety setting, that delay is uncomfortable. The team wanted to see issues sooner, and they wanted to spend their time on judgment rather than on assembling spreadsheets.

The approach

We worked with the safety physicians and the data team to understand how they actually reviewed a study, then built an interactive review application around that workflow rather than replacing it.

• A daily data refresh, so the review always reflects current data.
• Statistical signal detection that flags events occurring more often than expected.
• Drill-down from a flagged signal to the patients and records behind it.
• Views that bring adverse events, laboratory results, and exposure together for a single subject.

The application was built to the sponsor's standards and runs inside their validated environment, so the output carries the documentation a regulated process requires.

The results

Safety review shifted from a monthly event to a continuous one. Signals that once took three weeks to confirm are now visible within days, and the review meeting works from live data rather than a month-old extract. The team spends less time preparing material and more time assessing what it means.

Just as important, the move did not add risk. Because the application lives in a validated environment and traces every value back to its source, it stands up to the same scrutiny as the manual process it replaced.
