Summary
"This trial is comparing the effectiveness and safety of sacituzumab tirumotecan (sac-TMT) combined with pembrolizumab to standard treatment in patients with triple-negative breast
Who is the study for?
This trial is for individuals with triple-negative breast cancer (TNBC) who didn't fully respond to neoadjuvant therapy and surgery. Participants must have completed any required radiation, be able to continue on pembrolizumab, and not show signs of cancer relapse. Strict contraception or abstinence is required for both male and female participants during the trial and for a period after.
What is being tested?
The study compares sacituzumab tirumotecan (sac-TMT) combined with pembrolizumab against the physician's choice of treatment in TNBC patients post-surgery without a pathological complete response. The main goal is to see if sac-TMT plus pembrolizumab improves disease-free survival compared to other treatments.
What are the potential side effects?
Potential side effects include those common to chemotherapy such as nausea, fatigue, hair loss, increased risk of infection due to lowered immunity, as well as specific reactions related to sac-TMT or pembrolizumab like infusion reactions or autoimmune-like symptoms.

Experimental Treatment
Active Control
Group I: Pembrolizumab + sac-TMTExperimental Treatment2 Interventions
Participants receive pembrolizumab every 6 weeks (q6w) in combination with sac-TMT every 2 weeks (q2w) for 24 weeks. In addition, participants receive an antihistamine, an H2 antagonist of investigator's choice, acetaminophen (or equivalent), and dexamethasone (or equivalent) per each drug's product label prior to sac-TMT infusions.
Group II: Treatment of Physician's ChoiceActive Control2 Interventions
Participants receive pembrolizumab q6w or pembrolizumab q6w in combination with capecitabine (twice daily \[BID\] on Days 1 to 14 and 22 to 35 every 42 days x 4 \[2 weeks 1, 1 week off\]) for 24 weeks.
