TACTIVE-U: Um estudo para aprender sobre o medicamento em estudo (Vepdegestrant) quando administrado com outros medicamentos em pessoas com câncer de mama avançado ou metastático. (Subestudo C)
TACTIVE-U: UMA SEGURANÇA E EFICÁCIA INTERVENCIONAL FASE 1B/2, ESTUDO GUARDA-CHUVA DE RÓTULO ABERTO PARA INVESTIGAR A TOLERABILIDADE, PK E ATIVIDADE ANTITUMORAL DO VEPDEGESTRANT (ARV-471/PF-07850327), UMA PROTEÓLISE ORAL DIRECIONADA À QUIMERA, EM COMBINAÇÃO COM OUTROS TRATAMENTOS ANTI-CÂNCER EM PARTICIPANTES COM 18 ANOS OU MAIS COM CÂNCER DE MAMA ER+ AVANÇADO OU METASTÁTICO, SUBESTUDO C (ARV-471 EM COMBINAÇÃO COM SAMURACICLIB)
The purpose of this study is to learn about the safety and effects of the study medicine called vepdegestrant. The safety and effects of vepdegestrant will be see when given with other medicines. Vepdegestrant is studied to see if it can be a possible treatment for advanced metastatic breast cancer. This type of cancer would have spread from where it started (breast) to other parts of the body and would be tough to treat.
The study is seeking for participants who have breast cancer that:
- is hard to treat (advanced) and may have spread to other organs (metastatic). is sensitive to hormonal therapy (it is called estrogen receptor positive).
- is no longer responding to treatments taken before starting this study.
This study is divided into separate sub-studies.
For Sub-Study C:
All the participants will receive vepdegestrant and a medicine called samuraciclib.
Vepdegestrant and samuraciclib will be taken once in a day by mouth. The medicines will be taken at home. The experience of people receiving the study medicines will be studied. This will help see if the study medicine is safe and effective.
Participant will continue to take vepdegestrant and samuraciclib 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.

Descrição detalhada
C4891024 is a prospective, open-label, multicenter, Phase 1b/2 sub-study to evaluate the safety, antitumor activity, and PK of ARV-471 with samuraciclib in the treatment of participants with A/MBC. The sub-study is part of Umbrella platform, TACTIVE-U, comprising multiple sub-studies that independently evaluate ARV-471 in participants with Estrogen Receptor Positive/Human Epidermal Growth Factor Receptor 2 Negative (ER+/HER2-) Advanced or Metastatic Breast Cancer. ARV-471 will act as the backbone therapy given in combination with other anticancer agents thought to have clinical relevance in ER+ breast cancer.
