| Progression-Free Survival (PFS) | From the date of starting CDK4/6 inhibitor to the date of first documentation of progression or death (up to approximately 2.5 years) | PFS is defined as the time from the date of starting CDK4/6 inhibitor to the date of objective tumor progression as per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) or death from any cause in the absence of documented PD, whichever occurs first. |
Secondary
| Measure | Time frame | Description |
