Authorised Phase I and Phase II (Integrated)- Other ER +/HER2- Advanced or Metastatic Breast Cancer

TACTIVE-U: An Umbrella Study to Investigate the Safety and Antitumor Activity of Vepdegestrant (ARV-471) in Combination With Other Medicines in Adults With ER+ Advanced or Metastatic Breast Cancer, Sub-study A (ARV-471 and Abemaciclib)

EU CTIS ID: 2022-502228-34-00

What this study is testing

Phase 1b - To assess safety and tolerability of ARV-471 in combination with abemaciclib in participants with ER+/HER2- A/MBC to select a RP2D. Phase 2 - To assess the clinical antitumor activity of ARV-471 in combination with abemaciclib.

Who can take part

You may be able to join if

  • Participants aged 18 years or older (or the minimum age of consent in accordance with local regulations) at screening
  • Histological or cytological diagnosis of ER+ and HER2- A/MBC 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. - One, and only 1 line of any prior CDK4/6 inhibitor-based regimen is required (independent of the setting eg, adjuvant or advanced/metastatic). If prior CDK4/6 inhibitor was permanently discontinued due to an adverse event, the participant will not be eligible.
  • Participants must have at least 1 measurable lesion as defined by RECIST v1.1
  • Eastern Cooperative Oncology Group (ECOG) performance status ( PS) ≤1.

You likely can't join if

  • Participants in visceral crisis at risk of life-threatening complications in the short term.
  • Participants with a known history of drug-induced pneumonitis or other significant symptomatic deterioration of lung functions.
  • Participants with newly diagnosed brain metastases, or symptomatic central nervous system (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.
  • History of any other malignancies within the past 3 years, except for the following: (1) adequately treated basal or squamous cell carcinoma of the skin; (2) curatively treated in situ carcinoma of the cervix. All other malignancies must have been curatively treated and with no evidence of disease for >3 years. Participants with inflammatory breast cancer are excluded.
  • Impaired cardiovascular function or clinically significant cardiovascular diseases
  • Concurrent administration of medications, food, or herb supplements that are strong inhibitors and strong/moderate inducers of CYP3A, and drugs known to predispose to Torsade de Pointes or QT interval prolongation.
