Description
Summary
The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called ARV-471) when given together with other medicines for the potential treatment of advanced or metastatic breast cancer.
This study is seeking participants who have breast cancer that:
- is advanced, may have spread to other organs (metastatic) and cannot be fully treated by surgery or radiation therapy
- is sensitive to hormonal therapy (it is called estrogen receptor positive); and
- is no longer responding to previous treatments This study is divided into separate sub-studies.
For Sub-Study A:
All participants will receive ARV-471 and a medicine called abemaciclib. ARV-471 will be given by mouth, at home, 1 time a day. Abemaciclib will be given by mouth, at home, 2 times a day. We will examine the experiences of people receiving the study medicines. This will help us determine if the study medicines are safe and effective.
Participants will continue to take ARV-471 and abemaciclib until their cancer is no longer responding, or side effects become too severe. They will have visits at the study clinic about every 4 weeks.
Official Title
TACTIVE-U: An Interventional Safety and Efficacy Phase 1b/2, Open-label Umbrella Study to Investigate Tolerability, pk, and Antitumor Activity of Vepdegestrant (ARV-471/PF-07850327), an Oral Proteolysis Targeting Chimera, in Combination With Other Anticancer Treatments in Participants Aged 18 Years and Over With ER+ Advanced or Metastatic Breast Cancer, Sub-study A (ARV-471 in Combination With Abemaciclib)
Details
C4891006 is a sub-study from the Umbrella platform, TACTIVE-U, comprising multiple sub-studies that independently evaluate ARV-471 in participants with Estrogen Receptor Positive (ER+) Advanced or Metastatic Breast Cancer (A/MBC). ARV-471 will act as the backbone therapy given in combination with other anticancer agents thought to have clinical relevance in ER+ breast cancer.

Eligibility
You can join if…
Open to people ages 18 years and up
- histological or cytological diagnosis of ER+ and HER2- advanced/metastatic breast cancer that is not amendable to surgical resection with curative intent (≥1% ER+ stained cells on the most recent tumor biopsy).
- prior anticancer therapies: at least 1 and no more than 2 lines of prior therapies for advanced/metastatic disease; 1 line of any CDK4/6 inhibitor-based regimen is required (independent of the setting eg, adjuvant or advanced/metastatic)
- at least 1 measurable lesion as defined by RECIST v1.1.
- ECOG PS ≤1.
You CAN'T join if...
- visceral crisis at risk of life-threatening complications in the short term
- known history of drug-induced pneumonitis or other significant symptomatic deterioration of lung functions.
- newly diagnosed brain metastases, or symptomatic CNS metastases, carcinomatous meningitis, or leptomeningeal disease. Participants with a history of CNS metastases or cord compression are eligible if they have been definitively treated, clinically stable and discontinued anti-seizure medications and corticosteroids for at least 14 days prior to enrollment in the study.
