About this study
Official title: Phase I/II Open Label Non-randomised Safety and Efficacy Study of the Viral Vectored ChAd-MVA 5T4 Vaccine in Combination With PD-1 Checkpoint Blockade in Low- or Intermediate-risk Localized or Locally Advanced Prostate Cancer and Advanced Metastatic Prostate Cancer
This is a clinical trial of a new treatment for prostate cancer that is a type of vaccine that could be a new way to treat cancer. A vaccine that could alert the immune system to the presence of cancer cells in the body may enable the immune system to target and kill those cells effectively. This vaccine is intended to work by making the immune system kill cells that have a special protein (called 5T4) that is present on the surface of cancer cells. The vaccine is made up of two recombinant viruses ("ChAdOx1"- chimpanzee adenovirus Ox1 and "MVA" - modified vaccinia Ankara) that have been designed to produce the 5T4 protein and have been modified so that they are weakened and cannot reproduce themselves within the body like normal viruses. Once injected into the body, these viruses make the 5T4 protein and help the body's immune system to learn to target this protein and destroy cancer cells.
This vaccine will be used in combination with the immunotherapy drug called nivolumab which is an anti-PD-1 (Programmed Death protein-1) monoclonal antibody. This is a molecule that releases the brakes on the immune system and helps the immune system to kill cancer cells more efficiently. Nivolumab as a monotherapy was approved for treatment of several tumour types but not for the prostate cancer.
This study will evaluate the safety and efficacy of ChAdOx1-MVA 5T4 vaccine in combination with nivolumab in low and intermediate risk prostate cancer patients who have elected to have their prostate removed and in patients with advanced metastatic prostate cancer.
Read the detailed description
The purpose of this study was to evaluate the safety and efficacy of a combination of two new vaccines (ChAdOx1.5T4 and MVA.5T4) with a monoclonal antibody (PD-1 mAb, also known as Nivolumab and Opdivo®) against Prostate Cancer.
A vaccine that alerts the immune system to the presence of cancer cells in the body may enable the immune system to target and kill those cells effectively. This vaccine is intended to work by making the immune system kill cells that have a special protein (called 5T4) that is present on the surface of cancer cells. The use of two different forms of the vaccine has been shown to generate a more effective immune response.
ChAdOx1.5T4 consists of a virus (ChAdOx1), which is a weakened version of a chimpanzee adenovirus that has been genetically altered so that it is impossible for it to grow in humans. Modified Vaccinia virus Ankara (MVA) is licensed as third-generation vaccine against smallpox and serves as a potent vector system for development of new candidate vaccines against infectious diseases and cancer.
To both viruses we have added genes that make the 5T4 protein that is present in prostate cancer cells and which is essential to the cancer. By vaccinating, we are hoping to make the body recognise and develop an immune response to these proteins that will neutralise the effects of the cancer in human cells and therefore prevent the infection responsible for the disease.
Nivolumab (PD-1 mAb) is an immune checkpoint inhibitor. Immune checkpoints are a normal part of the immune system. Their role is to prevent an immune response from being so strong that it destroys healthy cells in the body. Immune checkpoints engage when proteins on the surface of immune cells called T cells recognize and bind to partner proteins on other cells, such as some tumour cells. These proteins are called immune checkpoint proteins. When the checkpoint and partner proteins bind together, they send an "off" signal to the T cells. This can prevent the immune system from destroying the cancer. Immunotherapy drugs called immune checkpoint inhibitors work by blocking checkpoint proteins from binding with their partner proteins. This prevents the "off" signal from being sent, allowing the T cells to kill the cancer cells. Nivolumab as a monotherapy has been approved for treatment of several tumour types but not currently for prostate cancer.
The intent was to have two cohorts of participants: Group 1 were patients who had been diagnosed with low- or intermediate-risk non-metastatic prostate adenocarcinoma and who were scheduled for radical prostatectomy; Group 2 comprised patients with metastatic castration resistant prostate cancer (mCRPC) with evidence of progression on anti-androgens.
Unfortunately, it proved impossible to recruit participants into Group 1, so the trial proceeded with just Group 2.
It was planned that the results would be measured by a composite response rate defined as one of the following:
- reduction of circulating tumour DNA of ≥50%
- serum PSA decrease of ≥50%
However, the analysis to measure the circulating tumour DNA (ctDNA) was not done for any of the participants due to the trial ending prematurely because of the COVID-19 pandemic in 2020.
The trial and the follow-up of participants was severely hampered by the Covid-19 pandemic.
In this study, we have shown that the candidate 5TA vaccines given were safe and well-tolerated. No serious adverse reactions occurred during the follow-up period. Most adverse events reported were mild or moderate in severity and all resolved spontaneously. The profile of adverse events reported in this trial is similar to other ChAdOx1 vectored vaccines.
- Being tested

ChAdOx1.5T4 will be administered intramuscularly in an extremity (e.g. thigh) at a dose of 2.5 x10^10 virus particles followed by MVA.5T4 administered via the same route at the dose of 2x10^8 plaque forming units
Nivolumab Infusion [Opdivo]Drug
Also called anti-PD-1 monoclonal antibody
Nivolumab is to be administered as a flat dose of 480 mg over approximately 60-minutes via IV infusion
| Study group | Role | What they receive |
|---|---|---|
| Intermediate risk prostate cancer | Experimental | ChAdOx1.5T4 on week 0 followed by booster injection of MVA.5T4 and nivolumab infusion on week 1. Patients will undergo radical prostatectomy on week 6. Receives: Biological: ChAdOx1-MVA 5T4 vaccine; Drug: Nivolumab Infusion [Opdivo] |
| Advanced metastatic prostate cancer | Experimental | ChAdOx1.5T4 on week 0 followed by booster injections of MVA.5T4 on week 4, ChAdOx1.5T4 on week 12 and MVA.5T4 on week 16. Nivolumab infusions are to be administered on week 4, 8 and 12. Receives: Biological: ChAdOx1-MVA 5T4 vaccine; Drug: Nivolumab Infusion [Opdivo] |
What is being measured
The primary outcome is the main question the study is designed to answer.
Safety - Incidence of Treatment-related Adverse Events.
Number of participants with treatment-related adverse events as assessed by CTCAE v4.0.
Note: All participants had one or more adverse events during the period they were monitored.
Measured: From baseline to 12 months
Efficacy - Measure Composite Response Rate Defined as One of the Following: 1) Change in Circulating Tumour DNA 2) Change in Serum PSA
Evaluate the efficacy by assessing the number of participants with 50% or more change in ctDNA or PSA concentration in the blood from baseline to 12 months post treatment.
Change in serum PSA was analysed for this outcome as one the two alternative methods planned.
As described in the trial overview, no ctDNA analysis was done due to the trial closing prematurely because of COVID-19 - by the time the pandemic had finished, the facility to perform the ctDNA analysis option was no longer available. Because no laboratory analysis was done, there is no data to report.
Measured: From baseline to 12 months
Secondary outcomes (4)
Evaluate Immune Responses to the Vaccine Antigen in the Periphery
Number of participants with peripheral 5T4-specific T cell responses secondary to treatment
Measured: From baseline to 12 months
Evaluate Immune Cell Subsets in the Prostate Secondary to Treatment (for Surgical Cohort)
Number of participants with intraprostatic infiltration of CD3+CD8+ T cells secondary to treatment
Measured: From baseline to radical prostatectomy, an expected average of 6 weeks
Evaluate Progression-free Survival Following Study Treatment (for Advanced Metastatic Cancer Cohort)
Evaluating the number of participants experiencing progression-free survival at 6 and 12 months post treatment
Measured: 6-12 months
Evaluate Overall Survival Following Study Treatment (for Advanced Metastatic Cancer Cohort)
Evaluating the number of participants experiencing overall survival at 6 and 12 months post treatment
Measured: 6-12 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing ChAdOx1-MVA 5T4 vaccine and Nivolumab Infusion [Opdivo] in people with Intermediate Risk Prostate Cancer and Castration-resistant Prostate Cancer, run by University of Oxford at 2 sites in United Kingdom.
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 17 inclusion and 15 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 25 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in United Kingdom. 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 25 Jun 2025). 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?
Safety - Incidence of Treatment-related Adverse Events. (time frame: From baseline to 12 months). 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?
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 25 Jun 2025; AzTrials last refreshed its copy on 7 Nov 2026.
