Abbreviated Title : Pembrolizumab in hypermutated breast cancer Trial Phase : II Clinical Indication : Hormone receptor-positive metastatic breast cancer Trial Type : Interventional Type of control : None Route of administration : Intravenous Trial Blinding : None Treatment Groups : Pembrolizumab Number of trial subjects : Approximately 150 patients will be prescreened with whole exome sequencing. Then 30 patients will be enrolled in the treatment phase.
Estimated enrollment period : 12 months Estimated duration of trial : The sponsor estimates that the trial will require approximately 24 months from the time the first subject signs the informed consent until the last subject's last visit.
Duration of Participation : 12 months Estimated average length of treatment per patient : 8 months

Experimental: pembrolizumab group
Drug:Pembrolizumab Dose/Potency:200 mg Dose Frequency:Q3W Route of Administration:IV infusion Regimen/Treatment Period:Day 1 of each 3 week cycle Use:Experimental
Trial treatment should be administered on Day 1 of each cycle after all procedures/assessments have been completed as detailed on the Trial Flow Chart. Trial treatment may be administered up to 3 days before or after the scheduled Day 1 of each cycle due to administrative reasons.
All trial treatments will be administered on an outpatient basis. Pembrolizumab 200 mg will be administered as a 30 minute IV infusion every 3 weeks. Sites should make every effort to target infusion timing to be as close to 30 minutes as possible. However, given the variability of infusion pumps from site to site, a window of -5 minutes and +10 minutes is permitted (i.e., infusion time is 30 minutes: -5 min/+10 min).

- Change of objective response rate(ORR) by RECIST 1.1 [ Time Frame: Every 3 cycles (each cycle is 21 days) ]Objective response rate (ORR) based on RECIST 1.1 in hormone receptor-positive, hypermutated metastatic breast cancer identified by whole exome sequencing (WES) Hypothesis: Pembrolizumab in patients with hormone receptor-positive, hypermutated metastatic breast cancer identified by WES will result in clinically meaningful ORR based on RECIST 1.1
- Clinical benefit rate(CBR) by RECIST 1.1 [ Time Frame: through study completion, an average of 1 year ]
