Recruiting PHASE3 Breast Neoplasms

Compares treatment options for Breast Neoplasms

Official title A Study of Sacituzumab Tirumotecan (MK-2870) as a Single Agent and in Combination With Pembrolizumab (MK-3475) Versus Treatment of Physician's Choice in Participants With HR+/HER2- Unresectable Locally Advanced or Metastatic Breast Cancer (MK-2870-010)

ClinicalTrials.gov ID: NCT06312176

What this study is testing

What is Sacituzumab tirumotecan?

Sacituzumab tirumotecan is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for breast neoplasms.

Also referred to as MK-2870.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The purpose of this study is to compare sacituzumab tirumotecan as a single agent, and in combination with pembrolizumab, versus Treatment of Physician's Choice (TPC) in participants with hormone receptor positive/human epidermal growth factor receptor-2 negative (HR+/HER2-) unresectable locally advanced, or metastatic, breast cancer. The primary hypotheses are that sacituzumab tirumotecan as a single agent and sacituzumab tirumotecan plus pembrolizumab are superior to TPC with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR) in all participants.
  • Phase 3: a large, late-stage study
  • This is a blinded study.

Who can take part

Ages 18 and older

You may be able to join if

  • Has unresectable locally advanced or metastatic centrally-confirmed hormone receptor positive (HR+)/human epidermal growth factor receptor 2 negative...
  • Has radiographic disease progression on one or more lines of endocrine therapy for unresectable locally advanced/metastatic HR+/HER2- breast cancer...
  • Is a chemotherapy candidate
  • Has an eastern cooperative oncology group (ECOG) performance status of 0 to 1 assessed within 7 days before randomization
  • Has adequate organ function

You likely can't join if

  • Has breast cancer amenable to treatment with curative intent
  • Has experienced an early recurrence (\<6 months after completing adjuvant/neoadjuvant chemotherapy) and therefore is eligible to receive second-line...
  • Has symptomatic advanced/metastatic visceral spread at risk of rapidly evolving into life-threatening complications
  • Has received prior chemotherapy for unresectable locally advanced or metastatic breast cancer
  • Active autoimmune disease that has required systemic treatment in the past 2 years

Who can join
  • Has unresectable locally advanced or metastatic centrally-confirmed hormone receptor positive (HR+)/human epidermal growth factor receptor 2 negative (HER2-) breast cancer
  • Has radiographic disease progression on one or more lines of endocrine therapy for unresectable locally advanced/metastatic HR+/HER2- breast cancer, with one in combination with a CDK4/6 inhibitor
  • Is a chemotherapy candidate
  • Has an eastern cooperative oncology group (ECOG) performance status of 0 to 1 assessed within 7 days before randomization
  • Has adequate organ function
  • Human immunodeficiency virus (HIV)-infected participants must have well controlled HIV on antiretroviral therapy
  • Participants who are Hepatitis B surface antigen (HBsAg) positive are eligible if they have received HBV antiviral therapy for at least 4 weeks, and have undetectable HBV viral load
  • Participants with a history of Hepatitis C virus (HCV) infection are eligible if HCV viral load is undetectable
What rules you out
  • Has breast cancer amenable to treatment with curative intent
  • Has experienced an early recurrence (\<6 months after completing adjuvant/neoadjuvant chemotherapy) and therefore is eligible to receive second-line (2L) treatment
  • Has symptomatic advanced/metastatic visceral spread at risk of rapidly evolving into life-threatening complications
  • Has received prior chemotherapy for unresectable locally advanced or metastatic breast cancer
  • Active autoimmune disease that has required systemic treatment in the past 2 years
  • History of (noninfectious) pneumonitis/interstitial lung disease that requires steroids, or has current pneumonitis/interstitial lung disease
  • Has an active infection requiring systemic therapy
