TREND-02 - a Phase II Exploratory De-escalation Trial of Neoadjuvant Sacituzumab Govitecan Plus Tislelizumab (SG/I) in Early Triple-negative Breast Cancer (TREND-02)

November 26, 2025 updated by: Yingying Xu, First Hospital of China Medical University
Refining neoadjuvant chemoimmunotherapy and establishing predictive biomarkers remain pivotal challenges in early TNBC. Although SG/I (sacituzumab govitecan/PD-1 inhibitor) shows clinical promise, validation of responder identification tools is warranted. This phase II trial aims to identify a precision TNBC population suitable for de-escalated neoadjuvant therapy with sacituzumab govitecan plus tislelizumab, based on differential Trop-2 expression (±) and PD-L1 status (CPS >10% vs. <10%). Primary endpoints include pCR rate and safety; exploratory biomarker analyses will assess mechanisms of response/resistance

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
