Extent of tumor AR staining and response to enobosarm in AR‐positive advanced breast cancer

Parameter	AR staining <40% (n = 22)	AR staining ≥40% (n = 24)
Mean PFS	2.92 months	7.89 months
Median PFS	2.75 months	5.5 months
ORR	0%	50%*
CBR	18%	79%*
PD	82%	21%*

^a p value <.0001 vs. AR staining <40%.

Abbreviations: AR, androgen receptor; CBR, clinical benefit rate; ORR, overall response rate; PD, progressive disease; PFS, progression‐free survival.
