Sac-TMT in Salivary Gland Cancers (Saint-Tropez)

5 novembre 2026 aggiornato da: Latin American Cooperative Oncology Group

Phase 2 Study of Sacituzumab Tirumotecan (Sac-TMT) in Salivary Gland Cancers - Saint-Tropez (LACOG 1824) Trial

This is a Phase 2, open-label, non-randomized, parallel, two-cohort study evaluating the efficacy and safety of Sacituzumab Tirumotecan (Sac-TMT, MK-2870) monotherapy in patients with advanced, recurrent, or metastatic salivary gland carcinomas who have received no more than 3 prior non-curative systemic treatment regimens. The study evaluates the activity of Sac-TMT separately in two independent cohorts based on tumor histology: Cohort 1 for Adenoid Cystic Carcinoma (ACC) and Cohort 2 for Non-Adenoid Cystic Carcinoma (non-ACC).

Descrizione dettagliata

Malignant salivary gland neoplasms are rare and heterogeneous malignancies with limited systemic treatment options and no widely established standard-of-care in advanced settings. Trophoblast cell surface antigen 2 (TROP-2) is broadly expressed in epithelial salivary gland carcinomas, making it a promising therapeutic target. Sacituzumab tirumotecan (Sac-TMT / MK-2870) is an antibody-drug conjugate (ADC) targeting TROP-2 coupled with a topoisomerase 1 inhibitor payload (KL610023).

This study aims to evaluate the clinical activity, safety, and patient-reported outcomes of Sac-TMT in two parallel, non-comparative cohorts:

Cohort 1: Patients with advanced/metastatic Adenoid Cystic Carcinoma (ACC). Cohort 2: Patients with advanced/metastatic Non-Adenoid Cystic Carcinoma (non-ACC).

Participants receive Sac-TMT at a dose of 4 mg/kg via intravenous (IV) infusion on Days 1 and 15 of each 28-day cycle for up to 12 cycles (approximately 1 year), or until disease progression, unacceptable toxicity, or withdrawal of consent. The primary objective is to evaluate the Objective Response Rate (ORR) according to RECIST 1.1 in each cohort. Secondary objectives include assessment of ORR by Independent Central Review (ORR-ICR), Disease Control Rate (DCR), Duration of Response (DoR), Progression-Free Survival (PFS), 6- and 12-month PFS, Overall Survival (OS), safety and tolerability, compliance, post-progression therapies, and Patient-Reported Outcomes (EORTC QLQ-C30 and EORTC QLQ-H&N43). Exploratory research will assess ctDNA dynamics and potential predictive/resistance biomarkers in baseline and serial blood and tissue samples.
