Open for Predictions · 3 endpoints

NCT03767244Pathological Complete Response Rate (pCR %)Primary

The percentage of patients with no residual invasive cancer at surgery. Common primary endpoint in neoadjuvant trials.

Prediction range: 0100 %
NCT03767244Hazard Ratio for Overall Survival (OS)Primary

A Hazard Ratio below 1.0 favours the treatment arm. HR 0.75 means a 25% reduction in the risk of death.

Prediction range: 0.41.2 Hazard Ratio
NCT03767244Hazard Ratio for Event-Free Survival (EFS)

A Hazard Ratio below 1.0 favours the treatment arm. HR 0.65 means a 35% reduction in the risk of progression or death.

Prediction range: 0.31.1 Hazard Ratio
