Registration Number
NCT04849364
Lead Sponsor
Bryan Schneider, MD
Brief Summary

This is a 3-arm study stratified by plasma ctDNA. Patients with residual TNBC disease after pre-operative therapy will be assigned to 1 of 3 Arms based on plasma ctDNA positivity and genomic marker(s).

Detailed Description

Participants that are plasma ctDNA positive with a genomic target will be assigned to one of the three groups in Arm 1 and receive genomically directed therapy.

* Arm 1a: DNA Repair pathway = talazoparib + capecitabine (CLOSED)

* Arm 1b: Immunotherapy pathway = pembrolizumab + capecitabine (CLOSED)

* Arm 1c: PI3K Pathway = inavolisib + capecitabine ---\> +/- standard of care pembrolizumab

* Arm 1d: DNA Repair + Immunotherapy = talazoparib + capecitabine +/- standard of care pembrolizumab

Participants that are plasma ctDNA positive without a genomic target will be assigned to Arm 2 and receive capecitabine and pembrolizumab or treatment of physician's choice.

Participants that are plasma ctDNA negative will be assigned to Arm 3 and receive any of the following based on patient and physician decision: no therapy/observation, capecitabine and pembrolizumab or treatment of physician's choice.

Arm 3CapecitabineArm 3 subjects have plasma ctDNA negative. Treatment of patient and physician's choice will be given with consideration for capecitabine and pembrolizumab. Dose, schedule and duration of treatment to be determined by treating physician.
Arm 1TalazoparibArm 1a: Patients who are ctDNA-positive and harbor a genomic target. DNA repair pathway = talazoparib + capecitabine (CLOSED) Arm 1b: Patients who are ctDNA-positive and harbor a genomic target. Immunotherapy pathway = pembrolizumab + capecitabine (CLOSED) Arm 1c: Patients who are ctDNA-positive and harbor a genomic target. PI3K Pathway = inavolisib + capecitabine ---\> +/- standard of care pembrolizumab Arm 1d: Patients who are ctDNA-positive and harbor a genomic target. DNA Repair + Immunotherapy = talazoparib + capecitabine +/- standard of care pembrolizumab

Primary Outcome Measures
NameTimeMethod
2 year Disease Free Survival (DFS) ARM 12 year

DFS is defined as the duration of time from arm assignment to time of a DFS event, defined as local failure (invasive), regional failure, distant failure, contralateral breast cancer (invasive or non-invasive), or death from any cause.

Secondary Outcome Measures
NameTimeMethod
Overall Disease Free Survival (DFS)2 years

Comparison of overall DFS in Arms 1, 2, 3; defined as the duration of time from arm assignment to time of a DFS event, defined as local failure (invasive), regional failure, distant failure, contralateral breast cancer (invasive or non-invasive), or death from any cause

2 year Disease Free Survival (DFS) in ARM 32 years

DFS is defined as the duration of time from arm assignment to time of a DFS event, defined as local failure (invasive), regional failure, distant failure, contralateral breast cancer (invasive or non-invasive), or death from any cause.

Overall Distant Disease Free Survival (DDFS)2 years

DDFS is defined as the duration of time from arm assignment to time of recurrence of breast cancer outside the breast and/or death from any cause.

5 year Overall Survival (OS)5 years

Overall survival is defined as the time from date of treatment start until death from any cause.

Frequency and Severity of Adverse Events1 year

Adverse events will be assessed using CTCAE criteria v5

2 year Disease Free Survival (DFS) in ARM 22 years
