Arm Intervention/treatment
Experimental: Elacestrant (formerly RAD1901) Drug: RAD1901
RAD1901, a novel selective ER degrader (SERD)
Other Name: Elacestrant



Primary Outcome Measures :
  1. To determine the effect of RAD1901 treatment on the estrogen receptor (ER) expression and estradiol binding to the ER in lesions from patients with metastatic breast cancer (mBC) [ Time Frame: 14 Days after the first dose ]

Secondary Outcome Measures :
  1. Correlation of FES uptake after RAD1901 treatment to clinical response [ Time Frame: Every 8 weeks for to up 12 months of treatment ]
  2. Tumor response will be evaluated in patients with measurable or evaluable disease, using RECISTv1.1 guidelines [ Time Frame: Every 8 weeks for to up 12 months of treatment ]
  3. Safety and Tolerability assessed in terms of adverse events, serious adverse events, ECG, physical examination, ECOG performance status, vital signs, and laboratory values [ Time Frame: Up to 30 days after the end of treatment ]
  4. Plasma concentrations of RAD1901 will be assessed at predefined intervals [ Time Frame: Every 28 days for up to 3 cycles ]
