UK Patients Testing World’s First Personalized mRNA Cancer Vaccine For Melanoma

(CTN News) – British patients are currently undergoing trials for a groundbreaking mRNA cancer vaccine tailored specifically for melanoma, with potential applications for lung, bladder, and kidney cancers as well.

This personalized vaccine, hailed as a “gamechanger,” is individually crafted for each patient within a matter of weeks, offering a beacon of hope for a cure.

Functioning by instructing the body to seek out and destroy cancer cells while thwarting their potential resurgence, this innovative vaccine has already shown promise in a stage 2 trial involving collaboration between pharmaceutical giants Moderna and MSD.

Results indicated a significant reduction in the risk of cancer recurrence among melanoma patients.

Now, the journey towards widespread application enters its final phase with a phase 3 trial spearheaded by the University College London Hospitals NHS Foundation Trust (UCLH).

Dr. Heather Shaw, serving as the national co-coordinating investigator for the trial, emphasized the vaccine’s potential to not only cure melanoma but also to be effective in combating other types of cancers.

In an exclusive reveal to the PA news agency, Dr. Shaw expressed profound excitement about the trial’s prospects, likening the vaccine to a culinary masterpiece akin to the offerings of a Michelin-starred restaurant.

She emphasized the intricate customization of the vaccine for each patient, highlighting the palpable enthusiasm among patients for this cutting-edge treatment.

mRNA-4157 (V940): Revolutionizing Cancer Treatment

The innovative jab, known as mRNA-4157 (V940), represents a pioneering approach in cancer treatment, functioning as an individualized neoantigen therapy (INT) with qualities akin to a cancer vaccine.

Engineered to ignite the immune system’s response tailored to the specific cancer and tumor of each patient, this jab targets tumor neoantigens, unique markers expressed by the tumors in question.

By carrying coding for up to 34 neoantigens, the jab prompts an anti-tumor immune reaction based on the distinct mutations present in the patient’s cancer.

Its creation involves the extraction of a tumor sample during surgery, followed by DNA sequencing and the application of artificial intelligence, culminating in the development of a personalized anti-cancer jab precisely attuned to the patient’s tumor.

Dr. Shaw emphasizes the individualized nature of this therapy, likening it to a bespoke solution tailored for each patient’s unique tumor landscape.

This highly personalized approach aims not only to treat the existing cancer but also to address the potential for recurrence, targeting any residual cancer cells undetectable by conventional imaging techniques.

The overarching goal of this therapy is nothing short of a cure, with the intention being to eradicate any lingering cancer cells and prevent recurrence.

Phase 2 data, published in December, demonstrated promising outcomes, showing that patients receiving the jab alongside MSD’s immunotherapy Keytruda experienced significantly reduced risks of cancer recurrence or death compared to those receiving Keytruda alone.

Now, as the phase 3 global trial commences, efforts are underway to broaden the scope of participants, with the aim of recruiting around 1,100 individuals.

The UK arm of the trial, spanning eight centers including London, Manchester, Edinburgh, and Leeds, seeks to enroll at least 60 to 70 patients, further advancing the pursuit of personalized and effective cancer treatment.

Advancing Cancer Treatment: The Promise of Combination Therapy Trials

The combination therapy is also undergoing trials for lung, bladder, and kidney cancer. One of the initial patients participating in the trial at UCLH is Steve Young, 52, from Stevenage.

What he initially perceived as a harmless “bump on the head” turned out to be melanoma, a diagnosis that came as a profound shock.

Reflecting on his journey, Young described grappling with the fear of a premature demise, particularly in light of his father’s early passing.

Learning about the trial at UCLH, especially the cutting-edge mRNA technology being utilized to combat cancer, ignited his curiosity and optimism. Young sees this therapy as his best chance to halt the progression of the disease.

Dr. Shaw shares Young’s optimism, noting the potential of these therapies to revolutionize immunotherapy. She highlights the quest for adjunctive treatments with minimal side effects, a need that these therapies appear poised to address.

Side Effects and Expert Endorsements

Common side effects include fatigue and mild discomfort at the injection site, comparable to those experienced with routine vaccinations.

Professor Lawrence Young of the University of Warwick echoes the sentiment, labeling this development as one of the most thrilling advancements in cancer therapy.

He emphasizes the promise demonstrated in patients with melanoma and anticipates the extension of this approach to other cancer types, such as lung and colon cancers.

Vassiliki Karantza, associate vice president of MSD Research Laboratories, underscores MSD’s commitment to pioneering research in early-stage cancer treatment.

She emphasizes the company’s dedication to expanding treatment options for patients with melanoma and beyond, reflecting a broader push towards innovative modalities in cancer therapy.
