Research summary
The study vaccine, AST-VAC2, will target the hTERT protein and help the immune system attack cancer cells. The vaccine is made by taking embryonic stem cells that have been obtained ethically from a single donor and developed in the laboratory to become dendritic cells. Dendritic cells occur naturally in the body as part of the immune system however these dendritic cells have a special role in finding proteins in the body which are associated with cancer and it is hoped that the vaccine will train the immune system to recognise these proteins and attack the cancer.
Some cancers have more of a certain type of protein called hTERT and it has been shown that targeting hTERT can lead to destruction of cancer cells by the immune system. Human Leukocyte Antigen (HLA) is another type of protein. If a HLA test shows that a patient is positive for a specific HLA protein, this may mean that there is a better chance of the vaccine attacking the cancer (AST-VAC2 can only work with some types of HLA).
The study is a first in man clinical trial and is in two parts. Part 1 will ensure that the vaccine can be given safely and if there are any initial signs of how it works in the body. Part 2 will continue looking at the safety but also how the vaccine works in a group of patients without measurable cancer.
Approximately 24 patients with non-small cell lung cancer (NSCLC) will be treated with AST-VAC2. This includes 12 patients in Part 1 of the study (patients with advanced disease) and 12 patients in the Part 2 of the study (after surgical treatment). Alongside patients who receive the vaccine, the study will also ask approximately 24 patients, who will not be eligible to receive the vaccine because of their HLA test result, to be part of an observation group. This group of patients will continue to receive standard care. The study will then compare the vaccine treated group with the observation group.
The three main aims are to find out:
• If the dose can be given safely.
• Potential side effects and how they can be managed.
• What happens to AST-VAC2 inside the body (looking for effects in blood, skin or tumour).REC name
