Conditions

Advanced or metastatic triple-negative breast cancer

Brief summary

Best tumor response (defined as PR or CR in the first 6 months of treatment, assessed by investigators per RECIST v1.1 criteria)

Detailed description

Time to response (TTR), Duration of Response (DoR), Progression free survival (PFS) and Overall Survival (OS), AEs and SAEs (all grade, per NCI-CTCAE v5.0), Association between PLX038 efficacy and homologous recombination (HR) defect (assessed by HR genes mutational status and BCRAness phenotype), replication stress-related biomarkers such as SFLN11 expression, RB1 loss, PK/PD analysis, Exploratory: Association between PLX038 efficacy and tumor or blood biomarkers., Exploratory: Centrally determined ORR and PFS.
