Area of Science:

• Oncology
• Immunology
• Biotechnology

Background:

• Messenger RNA (mRNA) vaccine technology, rapidly advanced during the COVID-19 pandemic, shows significant potential for cancer therapy.
• Therapeutic mRNA cancer vaccines are well-tolerated and represent a promising avenue for future cancer immunotherapy strategies.
• Technological innovations have enhanced mRNA vaccine stability, structure, and delivery, facilitating broader clinical application.

Purpose of the Study:

• To review recent clinical developments in mRNA-based cancer vaccines.
• To discuss optimal platforms for mRNA vaccine development.
• To analyze clinical use and therapeutic efficacy for future vaccine design.

Main Methods:

• Review of preclinical and clinical trial data on mRNA cancer vaccines.
• Analysis of technological advancements in mRNA vaccine platforms.
• Examination of clinical trial outcomes for monotherapy and combination treatments.

Main Results:

• Early clinical trials demonstrate promising results for mRNA vaccines, both alone and with checkpoint inhibitors.
• mRNA vaccines have shown potential in stimulating humoral and cellular immunity and overcoming tumor-induced immune suppression.
• Numerous clinical trials are enrolling patients with diverse tumor types to investigate mRNA vaccine therapy.

Conclusions:

• Therapeutic mRNA cancer vaccines are a viable option for immunotherapy, despite lacking full clinical approval.
• Personalized, tumor-dependent mRNA vaccines could overcome immune suppression and tumor relapse.
• Further research and clinical trials are essential to optimize the design and application of mRNA-based cancer vaccines.
