Summary

CUPCAKE is a randomized, non-comparative, multicenter, proof-of-concept phase II trial, using the Trials within Cohorts concept(1) to assess the clinical utility of ctDNA monitoring combined with 68Ga-FAPI-46-PET-CT imaging upon ctDNA detection for the surveillance of patients with a non-metastatic TNBC at high risk of relapse.

The study has two steps. In Step 1, patients who have completed the treatments for a localized TNBC will undergo ctDNA monitoring every \~4 months (± 2 weeks). In Step 2, patients for whom ctDNA will be detected will then be randomized between an observation arm, in which monitoring will continue until the detection of a clinical relapse, and an experimental arm, in which the ctDNA detection will be revealed to both the patient and the clinician: patients will then undergo a 18F-FDG PET-CT and a 68Ga-FAPI-46-PET-CT, in addition to whatever workup the investigator will deem necessary.

DIAGNOSTIC_TEST

ctDNA monitoring

For each patient included, a ctDNA detection assay will be performed in blood samples every 4 months, while extra-plasma will be banked. ctDNA results will be available with a turnaround time of less than 3 weeks. When negative, ctDNA detection results will not be disclosed to patients nor clinicians.

68Ga-FAPI-46-PET-CT

). To locate metastatic deposits, patients will be offered to undergo a whole-body imaging with 18F-FDG PET-CT and 68Ga-FAPI-46-PET-CT, in addition to any other workup considered as relevant by their treating physician.
