Pembrolizumab + Paclitaxel in Hormone Receptor-positive (HR+)/Human Epidermal Growth Factor Receptor 2-negative (HER2-) Non-luminal (by PAM50) Advanced Breast Cancer After Cyclin-dependent Kinase 4/6 (CDK4/6) Inhibitors Progression (TATEN)

Targeting Non-Luminal Disease by PAM50 With Pembrolizumab + Paclitaxel in Hormone Receptor-positive/HER2-negative Advanced/Metastatic Breast Cancer, Who Have Progressed on or After CDK 4/6 Inhibitor Treatment

This is an open-label, single arm, multicenter phase II study evaluating treatment with pembrolizumab in combination with paclitaxel in patients with locally advanced or metastatic non-luminal Hormone receptor-positive, HER2-negative (hereafter referred to as HR+/HER2-) breast cancer who had recurrence or progression while receiving previous therapy with a CDK inhibitor in the adjuvant setting or to treat advanced disease (or both).

Study Overview

• Status: Active, not recruiting
• Conditions: Metastatic Breast Cancer
• Intervention / Treatment: Drug: Pembrolizumab; Drug: Paclitaxel

Detailed Description

The study will utilize a 2-stage, single arm, Simon's 2-stage design1 with one (efficacy) interim and a final analysis. The interim analysis will be conducted when 15 patients are evaluable for Overall Response Rate (ORR) as determined locally by the investigator through the use of RECIST v.1.1. If 5 or fewer responses are observed in up to 15 patients of evaluable population (EP), the trial will be terminated in favor of the null for futility. Otherwise, up to a further 31 patients may be evaluated,for a maximum total of 46 evaluable patients. If a total of 19 or more responses are seen at the end of the second stage, then the null will have been rejected in favor of the alternative; and further investigation of the combination is warranted.

Recruitment will not be halted during the interim analysis period. Therefore, no interruption in the accrual will be done during the interim analysis in order to maintain the dynamic of accrual in the trial.

After confirmation of all eligibility criteria, eligible patients will receive pembrolizumab 200 mg every 3 weeks (on D1 of each 21-day cycle, beginning in Cycle 1) in combination with paclitaxel 80 mg/m2 administered at days 1, 8, 15 of each 21-day cycle beginning at cycle 2. Treatment will continue until disease progression, the development of unacceptable toxicity, withdrawal of consent, 24 months from the date of the first dose of pembrolizumab or end of study, whichever occurs first.

All patients will be followed for survival from screening until the last patient recruited has been followed for 12 months, has progressed or has died, whichever occurs first. The patient will be followed for survival approximately every 3 months (± 21 days) until death, withdrawal of consent, loss to follow-up, or study termination by the sponsor. In addition, information regarding use of subsequent anti-cancer agents for metastatic HR+/HER2- during the survival follow-up period will be collected.

Tumor assessments per Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1 and Immune-Related Response Evaluation Criteria In Solid Tumors (iRECIST) will be performed every 9 weeks (63 days ± 5 days) until disease progression, treatment discontinuation, the start of new anti-cancer treatment, withdrawal of consent, death, or the end of the study, whichever occurs first. Tumor assessments will be performed on the specified schedule regardless of treatment delays.

Safety assessments will include the incidence, nature, and severity of adverse events (AEs) and laboratory abnormalities graded per the NCI CTCAE v.5.

Laboratory safety assessments will include the regular monitoring of hematology, blood chemistry and pregnancy test

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Benefit Rate (CBR)	Proportion of patients with a best overall response of CR, PR or an overall lesion response of Stable Disease (SD) or Non-PR/Non-progression disease (PD) lasting ≥ 24 weeks, based on local investigator´s assessment according to RECIST v1.1. The CBR and its exact 90% confidence interval (CI).	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
Progression free survival (PFS)	PFS is defined as the time from the date of allocation to the date of the first documented progression or death due to any cause occurring in the study. PFS will be assessed based on local investigator's assessment according to RECIST v1.1. PFS will be censored if no PFS event is observed before the cut-off date. The censoring date will be the date of last adequate tumor assessment before the cut-off date. If a PFS event is observed after two or more missing or non-adequate tumor assessments, then PFS will be censored at the last adequate tumor assessment. If a PFS event is observed after a single missing or non-adequate tumor assessment, the actual date of event will be used. It is not intended to censor patients for new anticancer therapy prior to documented disease progression in the primary analysis.	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
Duration of response (DoR)	Time from the first occurrence of a documented objective response to disease progression, as determined locally by the investigator through use of RECIST v.1.1, or death from any cause, whichever occurs first. DOR only applies to patients whose best overall response is CR or PR according to RECIST v1.1 based on tumor response data per local investigator's assessment. The start date is the date of first documented response of CR or PR (i.e., the start date of response, not the date when response was confirmed), and the end date is defined as the date of the first documented progression or death due to underlying cancer. Patients continuing without progression or death due to underlying cancer will be censored at the date of their last adequate tumor assessment.	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
Time to response (TtR)	Time from allocation to the first objective tumor response (tumor shrinkage of ≥30%) observed for patients who achieved a CR or PR. TtR only applies to patients whose best overall response is CR or PR according to RECIST v1.1 based on tumor response data per local investigator's assessment.	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
Overall survival (OS)	Time from allocation to death from any cause. Data for patients who are alive at the time of the analysis data cutoff will be censored at the last date they were known to be alive. Data from patients without post-baseline information will be censored at the date of allocation. The results from log-rank test will be provided. The OS curve will be estimated by the Kaplan-Meier methodology, and the 95% CI will be estimated by the Cox proportional-hazards models.	From date of randomization to death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
PFS on study treatment compared to PFS on prior line of therapy (pre-PFS)	Time from allocation to the first occurrence of disease progression, as determined locally by the investigator through the use of RECIST v.1.1, or death from any cause, whichever occurs first compared to PFS on prior line of therapy. Pre-PFS only applies to patients whose received have previous treatment for metastatic disease	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
ORR according to PD1 messenger ribonucleic acid (mRNA) expression.	To evaluate the direct association of PD1 FFPE-based mRNA expression with ORR we evaluate the PD1 mRNA pre-established cutoff (median or tertiles) and a continuous variable. Median: Cutoff points are calculated according to the median value for the mRNA expression. Samples with mRNA expression above or equal to the median were considered as samples with high expression, while those with value below the median as samples with low expression. Tertiles: Cutoff points are calculated according to the tertiles value for the mRNA expression. Samples with mRNA expression above or equal to the tertile-1 (PD1-high) were considered as samples with high expression, samples with mRNA expression above or equal to the tertile-2 (PD1-high) were considered as samples with intermediate expression, while those with value below the tertile-2 as samples with low expression.	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
ORR according to early dynamic changes in circulating tumor DNA (ctDNA)	Correlation between ORR and ctDNA dynamic changes between baseline and after 1 cycle of pembrolizumab. The "circulating tumor DNA response" is defined as the ratio of mutant copies/ml of plasma at day 1 cycle 2 and day 1 cycle 1.	From date of randomization to disease progression, death, unacceptable toxicity, consent withdrawal or study termination, whichever came first, assessed up to approximately 24 months
PFS according to early dynamic changes in ctDNA	Correlation between PFS and ctDNA dynamic changes between baseline and after 1 cycle of pembrolizumab.
