Interventions
Registration Number
NCT05226871
Lead Sponsor
Pfizer
Brief Summary

The purpose of this clinical trial is to provide study medicine(s) and learn about their safety. This study is seeking participants who:

* Have benefited from ongoing study treatment as determined by the study doctor in a Pfizer-sponsored palbociclib Parent Study

* Must agree to follow the reproductive criteria

* Are willing and able to comply with all scheduled visits, treatment plans, and other study procedures

* Can give signed informed consent documents

Participants in this study will continue to receive treatment as they were in the parent study. The time by which participants will take part in this study is retrospective (after completed parent study). We will examine the experiences of people receiving the study medicine(s). This will help us determine if the study medicine(s) are safe. During this time, the participants will be monitored for the safety of the study medicine(s).

Detailed Description

This is an open-label study to provide continued access to treatment for eligible participants who continue to derive clinical benefit as determined by the investigator from study intervention(s) in a Pfizer-sponsored palbociclib clinical study (Parent Study)

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
