Doctors have initiated the world's first clinical trials of an mRNA lung cancer vaccine, touting its potential to save thousands of lives as groundbreaking. Lung cancer remains the leading cause of cancer-related deaths globally, with approximately 1.8 million fatalities each year. Survival rates, particularly for advanced forms of the disease, have been notably poor. However, experts are now testing an innovative jab that instructs the body to target and eliminate cancer cells while also preventing their recurrence. Known as BNT116 and developed by BioNTech, the vaccine aims to treat non-small cell lung cancer (NSCLC), the most prevalent form of the disease.

The phase 1 clinical trial for BNT116, the first human study of this mRNA vaccine, has commenced across 34 research sites in seven countries: the UK, US, Germany, Hungary, Poland, Spain, and Turkey. In the UK, the trial is being led by the University College London hospitals NHS foundation trust (UCLH) and encompasses six research sites across England and Wales. On Tuesday, the first UK patient received the vaccine, which will be administered alongside immunotherapy. A total of approximately 130 patients, ranging from early-stage to late-stage disease or recurrent cancer, will participate in the trial, including around 20 patients from the UK.

Similar to the mRNA technology employed in Covid-19 vaccines, BNT116 utilizes messenger RNA to prime the immune system by presenting it with tumor markers specific to NSCLC. This reinforcement of the body's immune response to cancer aims to selectively target cancer cells while sparing healthy cells, unlike traditional chemotherapy treatments. Professor Siow Ming Lee, a consultant medical oncologist at UCLH, expressed enthusiasm about this new frontier of mRNA-based immunotherapy clinical trials for lung cancer treatment, emphasizing its efficacy and ease of administration.

Janusz Racz, a 67-year-old AI specialist from London, volunteered to participate in the trial as he believed in the progress of science and wanted to be a part of improving cancer treatment outcomes. Racz, who was diagnosed with lung cancer in May and initiated chemotherapy and radiotherapy shortly after, expressed his hope that this new methodology could help eradicate his cancer and ultimately save countless lives.

Racz received the vaccine, comprised of six consecutive injections given every five minutes over 30 minutes, at the National Institute for Health Research UCLH Clinical Research Facility. He will receive the vaccine weekly for six weeks, followed by administration every three weeks for 54 weeks. Professor Lee emphasized the goal of preventing cancer recurrence, as lung cancer often returns even after surgery and radiation.

The potential of the mRNA vaccine to complement existing immunotherapy treatments and improve survival rates has fueled optimism among researchers. Professor Lee, who has been dedicated to lung cancer research for four decades, recalled a time when the effectiveness of chemotherapy was doubted. He noted that advancements in immunotherapy have already improved survival rates for stage 4 lung cancer patients to 20-30%. The addition of the mRNA vaccine, alongside immunotherapy, is expected to provide an extra boost and potentially become a standard of care worldwide.

In May, The Guardian reported on a groundbreaking NHS initiative to fast-track thousands of patients in England into clinical trials for cancer vaccines. This "matchmaking" scheme aims to offer eligible patients access to innovative cancer treatments, including vaccines, that could revolutionize cancer care. Lord Vallance, the science minister, praised the launch of the lung cancer vaccine trial, highlighting its potential to save the lives of numerous lung cancer patients.

As Janusz Racz looks forward to completing his treatment and pursuing his dream of running the London Marathon, he symbolizes the hope that this pioneering lung cancer vaccine brings to patients worldwide. With continued support for groundbreaking therapies in medical research, there is optimism for a future where lung cancer becomes a more manageable and survivable disease.
