Read the detailed description

Pembrolizumab 2mg/kg administered intravenously over 30 minutes every 3 weeks. Pembrolizumab will be infused prior to the start of the assigned monoclonal antibody (Mab) arm. .

Dosing for the Mab arms will begin as follows:

Arm 1: Cycle length is 21 days. Intravenous (i.v.) trastuzumab 6 mg/kg on day 1 every 21 days.

Arm 2: Cycle length is 21 days. i.v. ado-trastuzumab emtansine 3.6 mg/kg on day 1 every 21 days.

Arm 3: Cycle length is 21 days. i.v. cetuximab 400 mg/m2 on cycle 1 day 1, then i.v. cetuximab 250 mg/m2 on day 8. Each subsequent cycle will be i.v. cetuximab 250 mg/m2 on days 1 and 8 every 21 days.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Pembrolizumab, Trastuzumab and ado-trastuzumab emtansine in people with Advanced Cancer and Breast Cancer, run by Western Regional Medical Center 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 19 inclusion and 13 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: stopped early, as of the sponsor's last update on 21 Oct 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Yes. Results are posted in the registry (first posted 2 Nov 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Determine the Recommended Phase 2 Dose (RP2D) of Monoclonal Antibody Therapy (Mab) in Combination With Pembrolizumab (Pembro) in Subjects With Advanced Cancer (time frame: 3 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 Oct 2019.
