SAGA—a phase Ib/II single-arm, multicenter study of sacituzumab govitecan for patients with metastatic esophagogastric adenocarcinoma
Background
Treatment of metastatic and locally advanced unresectable esophagogastric adenocarcinoma (EGA) after first-line therapy has limited efficacy. Sacituzumab govitecan (SG) is an antibody-drug conjugate (ADC) linking a TROP-2-directed antibody to the topoisomerase-I inhibitor SN-38. EGA has a high TROP-2 positivity rate and is sensitive to topoisomerase inhibition. Thus far, limited data on the efficacy and safety of SG in this patient population are available.
Aim
To evaluate the safety and efficacy of SG in patients with metastatic EGA who progressed under previous treatment. Objective response rate (ORR) is the primary endpoint.
Trial design
SAGA is a single-arm, non-randomized, open-label multicenter phase Ib/II study. Patients after prior treatment with a fluoropyrimidine-platinum-containing chemotherapy with or without targeted therapy or immunotherapy will be treated with SG intravenously at a dose of 10 mg/kg body weight on days 1 and 8 of a 21-day treatment cycle. After a run-in phase of 20 patients, safety and efficacy will be evaluated and the trial will proceed to a recruitment goal of 56 patients when at least two tumor responses are documented in the run-in phase. A hypothesis of an ORR of 16% is tested against a null hypothesis of an ORR of 5%.
Trial identifiers
