About this study

Official title: A Randomised Phase II Study of Pembrolizumab With or Without Bevacizumab in Platinum-resistant Recurrent/Metastatic Nasopharyngeal Carcinoma

This is a single center, randomized, phase Ib/II open-label study of pembrolizumab (pembro or MK-3475) with or without bevacizumab in patients with recurrent non-curable or metastatic nasopharyngeal carcinoma (NPC).

Read the detailed description

The study will consist of 2 treatment arms. In Treatment Arm A, patients will be treated with intravenous pembrolizumab alone, 21-day cycle. For Treatment Arm B, patients will receive intravenous pembrolizumab preceded by an infusion of bevacizumab (Day 1 of 21-day cycle). Each treatment cycle is 3 weeks. Up to 48 patients will be enrolled in this study in 2 stages. The first stage will consist of 30 patients and the remaining 18 patients will be added if interim data looks promising.

Eligible patients will be randomized 1:1 into either Treatment Arm A or Arm B. Treatment will continue until tumor progression, intolerance to treatment, or up to 2 years (32 doses of pembrolizumab/bevacizumab). For patients who have progressed on pembrolizumab alone, cross over to Arm B is allowed, with repeat biopsy of the lesions before and 1 week after starting bevacizumab. Patients who discontinue from the trial will not be replaced.

The study will collect serial samples of tumor tissue and blood to determine the PD biomarkers of immune activation, in the tumor and systemically, following treatment. This is expected to provide preliminary evidence for immune stimulation using both pembrolizumab and bevacizumab in NPC. The tumor biopsies will also present an opportunity to determine the molecular details of tissue and tumor response to anti-angiogenic therapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary endpoint of ORR

    Comparison of the two treatment arms will be evaluated using the Fisher's exact test. The treatment effect will be quantified via the relative risk estimate and its associated 95% confidence interval (CI).

    Measured: 2 years

  2. The secondary endpoint of PFS

    This will be summarized using the Kaplan-Meier survival estimate for each group. As an exploratory analysis, the log-rank test will be used for comparing differences in PFS, with its effect quantified based on hazard ratio and its 95% CI.

    Measured: 2 years

  3. Progression free survival (PFS)

    This is defined as the time from randomization to the first documented disease progression per RECIST 1.1 based on blinded central imaging assessment or death due to any cause, whichever occurs earlier.

    Measured: 2 years

What is this clinical trial studying?

A Phase 1/2 study testing pembrolizumab and bevacizumab in people with Locally Recurrent Cancer and Metastatic Nasopharyngeal Cancer, run by National University Hospital, Singapore at 1 site in Singapore.

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 12 inclusion and 24 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: under way, not looking for participants, as of the sponsor's last update on 22 Nov 2024. 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 Singapore. 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?

This study is still under way. Results are not available in the source record yet.

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?

Primary endpoint of ORR (time frame: 2 years). The study lists 3 primary outcomes in all. 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 NCT03813394, which also lists 4 linked publications.

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 22 Nov 2024.
