About this study

Official title: A Prospective Cohort Study of Integrating Radiotherapy Into Chemotherapy With Pembrolizumab and Bevacizumab in Newly Diagnosed Stage IVB Cervical Cancer

This phase I/II trial tests the safety and effectiveness of receiving external beam radiation therapy (EBRT) and brachytherapy along with chemotherapy, consisting of cisplatin and paclitaxel, and immunotherapy, consisting of bevacizumab and pembrolizumab, for the treatment of patients with stage IVB cervical cancer. EBRT is type of radiation therapy that uses a machine to aim high-energy rays at the cancer from outside of the body. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may kill them. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. A monoclonal antibody, such as pembrolizumab, is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Giving EBRT and brachytherapy along with chemotherapy and immunotherapy may be a safe and effective way to treat patients with stage IVB cervical cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To demonstrate that radiotherapy can be safely integrated into chemotherapy and pembrolizumab with bevacizumab in newly diagnosed stage IVB cervical cancer to improve outcomes.

SECONDARY OBJECTIVE:

  1. To demonstrate improvements with overall response rate, overall survival (OS), and duration of response with the addition of radiation therapy to standard of care in stage IVB cervical cancer.

EXPLORATORY OBJECTIVES:

  1. To demonstrate improved quality of life and disease-related toxicity with the addition of radiation therapy to standard of care chemotherapy in stage IVB cervical cancer.

II. To explore the association of known risk factors (age, race/ethnicity, smoking status, baseline quality of life, combined positive score [CPS] score 1-10 versus > 10, and performance status with the change in QOL, treatment outcomes, and toxicities.

III. To explore circulating tumor deoxyribonucleic acid (ctDNA) as a biomarker to monitor the response to upfront chemotherapy-immunotherapy and subsequent radiation.

IV. To use T cell receptor repertoire sequencing (TCRseq) to define T cell clones present in the tumor and to establish their concordance with peripheral blood T cell clones at baseline and in response to therapy.

OUTLINE:

PART 1: Patients receive cisplatin intravenously (IV), paclitaxel IV, pembrolizumab IV over 30 minutes, and bevacizumab IV on day 1 of each cycle. Cycles repeat every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients receive no treatment for 3 weeks.

PART 2: Patients undergo EBRT for 25 treatments delivered over 5 weeks, and brachytherapy over 3-5 treatments. Patients also receive pembrolizumab IV over 30 minutes and bevacizumab IV on day 1 of each cycle. Cycles for immunotherapy repeat every 21 days for a total of 2 years in the absence of disease progression or unacceptable toxicity. Participants who complete study intervention after 2 years of pembrolizumab are eligible for up to 1 year of additional pembrolizumab (second course) upon experiencing disease progression.

Patients undergo computed tomography (CT), positron emission tomography (PET)/CT, and/or magnetic resonance imaging (MRI) throughout the study. Patients also undergo blood sample collection throughout the study.

After completion of study treatment, patients follow up at 30 days and every 6 weeks for up to 1 year then every 9 weeks.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Bevacizumab, Biospecimen Collection and Brachytherapy in people with Cervical Adenocarcinoma and Cervical Adenosquamous Carcinoma, run by Jonsson Comprehensive Cancer Center at 4 sites 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 31 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: looking for participants now, as of the sponsor's last update on 12 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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?

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?

Contact Jenny Lester (310-794-9728, JLester@mednet.ucla.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression free survival (PFS) (time frame: From the date of cycle 1 of chemotherapy (per protocol) to tumor progression or recurrence at any site, commencement of non-protocol anticancer therapy or death from any cause, whichever occurs first, up to 3 years). The study lists 2 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 NCT06543576.

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 12 Aug 2026.
