A previous clinical trial used a cancer vaccine to treat prostate cancer. The results showed promise treating the cancer with minimal serious side effects. Based on those results, researchers will test the vaccine for pleural mesothelioma.
The UV1 cancer vaccine targets cells that produce large amounts of telomerase. This includes prostate and mesothelioma cancer cells. Pleural mesothelioma patients will receive multiple vaccinations and immunotherapy treatment.

This vaccine is a UV1 vaccination. It targets cells producing large amounts of telomerase. Although prostate cancer and mesothelioma are very different, they both have this characteristic.
The UV1 vaccine contains small fragments of telomerase. This teaches the body’s immune system which protein to identify and attack. In this case, the protein is telomerase.
DNA damage can lead to cell death. Telomerase is a protein that helps cells fix certain types of DNA damage. Therefore, telomerase can help cancer cells survive.
Researchers have tested the UV1 vaccine on prostate cancer patients. The study consisted of 22 men who received 7 – 13 vaccinations. Study results concluded:
Doctors collected results during a follow-up nine months after the first vaccination. Later follow-ups could show differences in this data.
Side effects emerging from the prostate cancer study included:
Two patients experienced anaphylactic shock. One patient experienced dangerously low platelet levels. These side effects were not seen in the majority of patients.
All cancer treatments have potential side effects. Patients should discuss any treatment concerns with their care team. Palliative treatments are often available to help manage patient discomfort.
The upcoming clinical trial* will focus on 118 mesothelioma patients with:
*The ClinicalTrials.gov Study Record Detail provides more information about the study.
In addition to the vaccination, patients will also undergo immunotherapy treatment. This will involve two immunotherapy drugs: Yervoy®️ (ipilimumab) and Opdivo®️ (nivolumab).
To determine the effectiveness of the treatment, doctors will divide patients into two groups:
Although there is no cure for mesothelioma, researchers continue to look for treatments to improve survival. The cancer vaccine could help:
All of these outcomes have the potential to improve patient survival.
Researchers expect to have preliminary results from the study in 2022.
Viable treatment options vary from patient to patient. Additionally, clinical trials have eligibility requirements a patient must meet to participate. Patients should consult with a mesothelioma specialist to learn more.
