Statistical Analysis Plan Aug. 2021
Only pulled from it all CTC & PD-L1 references.
Maybe something helpful, maybe not....
Under #3, Treatment Period:
Additionally, a blood sample will be collected prior to treatment administration for CTCs PD-L1/CCR5, and CTC - CAMLs analysis.

2.4.3 Exploratory Outcome Measures
• Measure immune biomarkers (PD-L1) in CTCs, metastatic tissue and immune cells such as
CAMLs and correlate with therapeutic benefit (PFS); and
• Correlation between CCR5 expression (CTCs, CAMLs) and PD- L1 expression.
__
8.3.6.1 Measure immune biomarkers (PD-L1) in CTCs, metastatic tissue and immune cells such
as CAMLs and correlate with therapeutic benefit (PFS) Immune biomarkers (PD-L1) in CTCs, metastatic tissue and immune cells such as CAMLs will be related to PFS using Cox regression.
8.3.6.2 Correlation between CCR5 expression (CTCs, CAMLs) and PD- L1 expression
CCR5 expression (CTCs, CAMLs) and PD- L1 expression will be correlated using logistic
regression.
