Study Endpoints

Primary Endpoints

Invasive Disease Free Survival (iDFS) for Palbociclib vs. Placebo in Patients With High CPS-EG Score After Neoadjuvant Chemotherapy Receiving Standard Adjuvant Endocrine Therapy for HR-positive/HER2-normal Primary Breast Cancer.
From date of randomisation to data cut off: 24 August 2020 (approximately 6 years and 6 months)

Invasive disease-free survival (iDFS) is defined according to Hudis (J Clin Oncol 2007) as the time period between randomization and first event (ipsi- or contralateral invasive in-breast or loco-regional recurrence, distant recurrence, death from breast cancer, death from non-breast cancer cause, death from unknown cause, invasive contralateral breast cancer, second primary invasive cancer (non-breast)) assessed until the end of study.

Secondary Endpoints

iDFS Excluding Second Non-breast Cancers
From date of randomisation to data cut off: 24 August 2020 (approximately 6 years and 6 months)

Frequently asked questions about Palbociclib PD-0332991

What is Palbociclib PD-0332991 used for in breast cancer?

Palbociclib PD-0332991 is an investigational small molecule being studied for the treatment of breast cancer, specifically in hormone receptor positive, HER2 normal patients with residual disease after neoadjuvant chemotherapy and surgery. It is being evaluated in a Phase 3 clinical trial as an addition to standard endocrine treatment.

What does Palbociclib PD-0332991 target?

Palbociclib PD-0332991 is a CDK 4/6 inhibitor, as indicated by its use in the postneoadjuvant treatment setting for hormone receptor positive, HER2 normal breast cancer. It targets cyclin-dependent kinases 4 and 6, which are involved in cell cycle regulation and are commonly dysregulated in cancer.

Who makes Palbociclib PD-0332991?

Palbociclib PD-0332991 is being developed by Pfizer, Inc., a company traded on the New York Stock Exchange under the ticker symbol PFE. Pfizer is conducting the clinical development of this drug for the breast cancer indication.
