About this study

Official title: A Phase II Trial Evaluating Safety and Efficacy of Pembrolizumab and Cisplatin in Patients With Advanced Triple Negative Breast Cancer

This is a Phase II treatment study that is done to evaluate how effective and safe the combination of pembrolizumab and cisplatin work in treating participants with triple-negative breast cancer that had spread to other parts of the body, has come back, or cannot be removed by surgery. Pembrolizumab (investigational drug) is a monoclonal antibody that works by helping your immune system to fight cancer. Cisplatin is a chemotherapy drug that works by interfering with tumor cell division. Studies also suggest that treatment with chemotherapy, like cisplatin, may improve the effectiveness of pembrolizumab. This study will test the effectiveness of pembrolizumab and cisplatin in participants with advanced triple-negative breast cancer.

Read the detailed description

Participants will receive pembrolizumab intravenously (IV) over 30 minutes and cisplatin once every 3 weeks for a total of 6 doses. Both drugs are given by vein (Intravenous(IV)) on day 1. Participants that are responding to the study treatment will continue to receive pembrolizumab alone for up to 24 months until disease gets worse, having bad side effects, no longer wish to be in the study, or have become pregnant (whichever comes first).

In addition to study drug administration visits, participants will be asked to have physical exams, blood draws every three weeks and tumor evaluation using MRI or CT scans every 9 weeks.

After completion of study treatment, participants are followed up for safety within at 30 days of last dose of study treatment and then every 12 weeks until study completion.

Study groupRoleWhat they receive
Treatment (pembrolizumab, cisplatin)ExperimentalParticipants receive pembrolizumab and cisplatin once every 3 weeks for a total of 6 doses. Both drugs are given by vein (IV). Participants that are responding to the study treatment will continue to receive pembrolizumab alone beyond 6 cycles for up to 24 months until disease gets worse, having bad side effects, no longer wish to be in the study, or have become pregnant (whichever comes first). Participants receive pembrolizumab over 30 minutes and cisplatin on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Participants without disease progression after 6 courses may continue on pembrolizumab IV on day 1 every 21 days for up to 24 months (or 35 courses) in the absence of disease progression or unacceptable toxicity.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pembrolizumab and Cisplatin in people with Estrogen Receptor Negative and HER2/Neu Negative, run by University of Washington at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 26 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To evaluate the efficacy of combination pembrolizumab and cisplatin in participants with advanced TNBC (time frame: Up to 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03644589.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Apr 2019.
