Lung cancer remains one of the most lethal forms of cancer globally, accounting for an estimated 1.8 million deaths in 2020 alone. However, a groundbreaking development in cancer treatment has recently emerged with the initiation of clinical trials for a novel mRNA-based vaccine designed to combat non-small cell lung cancer (NSCLC), the most common form of lung cancer. BioNTech, the German biotechnology company famous for developing effective COVID-19 vaccines using mRNA technology, has created this innovative form of immunotherapy, known as BNT116.
The BNT116 Vaccine: Mechanism and Potential
BNT116 uses messenger RNA (mRNA) to present common tumour markers from NSCLC to the patient’s immune system. This approach aims to enhance the immune response against cancer cells while minimizing damage to healthy cells, a huge advantage over traditional chemotherapy. The vaccine is designed to be highly targeted, focusing on specific markers expressed by cancer cells, thereby reducing the risk of toxicity to healthy cells, unlike chemotherapy. This precision targeting is imperative as it could lead to fewer side effects and more effective treatment outcomes for patients.
The BNT116 vaccine is administered intravenously and comprises six mRNAs, each encoding a tumour-associated antigen (TAA) frequently expressed in NSCLC. These TAAs include MAGE A3, CLDN6, KK-LC-1, PRAME, MAGE A4, and MAGE C1, which are used to stimulate a precise and robust immune response against tumour cells. By leveraging mRNA technology, BioNTech aims to create a vaccine that not only treats existing cancer but also potentially prevents recurrence by bolstering the immune system’s ability to recognize and destroy cancer cells.
Clinical Trials and Research Sites
The clinical trial for BNT116 is being conducted across 34 research sites in seven countries, including the UK, US, Germany, Hungary, Poland, Spain, and Turkey. In the UK, the NIHR UCLH Clinical Research Facility serves as the lead research site, with six additional UK sites participating in the study. Approximately 130 participants with varying stages of NSCLC will be enrolled, from early-stage disease before surgery or radiotherapy to late-stage or recurrent cancer. This diverse enrollment strategy allows researchers to assess the vaccine’s efficacy across different disease stages.
Janusz Racz, a 67-year-old from London, became the first participant in the UK to receive the BNT116 vaccine. His involvement in the trial reflects a broader hope among patients and researchers that this vaccine could revolutionize lung cancer treatment by providing a more targeted and less invasive alternative to chemotherapy. Racz noted that the vaccine was painless and preferable to chemotherapy, highlighting the potential for improved patient experiences with mRNA-based treatments.

The Role of the UK in mRNA Cancer Vaccine Research
The UK is at the forefront of mRNA cancer vaccine research, driven by its robust life sciences sector and government support. The Office for Life Sciences has played a crucial role in laying the groundwork for these advancements. Collaborations between institutions like University College London Hospitals (UCLH), the National Institute for Health and Care Research (NIHR), and industry partners such as BioNTech highlight the UK’s capacity to innovate in cancer treatment.
UCLH’s Director of Research, Professor Karl Peggs, emphasizes the importance of developing new therapies, and the involvement of leading clinicians and researchers, combined with state-of-the-art facilities, positions the UK as a hub for mRNA-based immunotherapies. Science Minister Lord Vallance has underscored the potential of these vaccines to save thousands of lives annually, reflecting the UK’s commitment to turning research into groundbreaking treatments.
Objectives and Expected Outcomes
The primary objective of the BNT116 trial is to determine the safety and tolerability of the vaccine. Researchers will also investigate the vaccine’s effectiveness both as a monotherapy and in combination with established treatments like chemotherapy and immunotherapy. By assessing the combined effects of BNT116 with other therapies, scientists aim to enhance treatment outcomes for NSCLC patients. A key benefit of this approach is its potential to decrease lung cancer recurrence, which could improve long-term survival rates for patients.
Positive results from this trial could pave the way for mRNA cancer vaccines to become a standard treatment option globally. The success of such vaccines would not only transform the landscape of lung cancer treatment but also open new avenues for treating other cancers using mRNA technology As NHS England national cancer director Dame Cally Palmer noted, the NHS has a leading role in trialing cancer vaccines, and successful outcomes could be revolutionary in preventing cancer recurrence after initial treatment.
Future Prospects and Challenges
While the BNT116 trial represents a promising step forward in lung cancer treatment, several challenges do still remain. The trial’s success will depend on demonstrating not only the safety and tolerability of the vaccine but also its effectiveness in improving patient outcomes. As with any new therapy, there are always risks and uncertainties, including potential side effects and the need for long-term follow-up to assess durability of response.
Despite these challenges and the novelty of this treatment, the potential benefits of mRNA cancer vaccines are substantial. By harnessing the immune system to target cancer cells specifically, these vaccines could offer a more sustainable and less toxic alternative to traditional treatments. The integration of mRNA technology into cancer treatment could also accelerate the development of vaccines for other types of cancer, leveraging the immune system’s natural defenses to combat disease.
The initiation of the BNT116 clinical trial marks an exciting era in lung cancer research, offering hope for improved treatment outcomes and reduced recurrence rates. As the trial progresses, the global medical community will closely monitor its results, anticipating the potential for mRNA vaccines to transform the landscape of cancer treatment worldwide.
