Official title

An Open-label, Randomized Phase 3 Study of MK-2870 as a Single Agent and in Combination With Pembrolizumab Versus Treatment of Physician's Choice in Participants With HR+/HER2- Unresectable Locally Advanced or Metastatic Breast Cancer

Overview

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.

Interventions

  • Drug Sacituzumab tirumotecan
    IV infusion
  • Biological Pembrolizumab
    IV infusion
  • Drug Paclitaxel
    IV infusion
  • Drug Nab-paclitaxel
    IV infusion
  • Drug Capecitabine
    oral tablet
  • Drug Liposomal doxorubicin

Primary outcome measures

Secondary outcome measures (12)
  • Overall Survival (OS) [Time frame: Up to ~77 months]
  • Progression-Free Survival (PFS) (pembrolizumab + sacituzumab tirumotecan + versus sacituzumab tirumotecan) [Time frame: Up to ~57 months]
  • Objective Response Rate (ORR) [Time frame: Up to ~57 months]
  • Duration of Response (DOR) [Time frame: Up to ~57 months]
  • Change from baseline in global health status/quality of life scores, on the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) [Time frame: Baseline and up to ~77 months]
  • Change from baseline in physical functioning score, on the EORTC QLQ-C30 [Time frame: Baseline and up to ~77 months]
  • Change from baseline in emotional functioning score, on the EORTC QLQ-C30 [Time frame: Baseline and up to ~77 months]
  • Change from baseline in fatigue score, on the EORTC QLQ-C30 [Time frame: Baseline and up to ~77 months]
  • Change from baseline in diarrhea score, on the EORTC QLQ-C30 [Time frame: Baseline and up to ~77 months]
  • Time to first Deterioration (TTD) in global health status/quality of life scores, on the EORTC QLQ-C30 [Time frame: Up to ~77 months]
  • TTD in physical functioning score, on the EORTC QLQ-C30 [Time frame: Up to ~77 months]
  • TTD in emotional functioning score, on the EORTC QLQ-C30 [Time frame: Up to ~77 months]

Eligibility criteria

Inclusion criteria

  • 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

Exclusion criteria

  • 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
