Hope to Eradicate Lung Cancer, Colorectal Cancer, and Various Solid Tumors! China’s First Self-Replicating mRNA Vaccine JCXH-211 Successfully Launched~
mRNA Vaccine
Tumor immunotherapy, as an emerging method for diagnosing and treating tumors, has garnered widespread attention since its inception. Prior to the advent of tumor immunotherapy, the clinical treatment of solid tumors relied solely on traditional surgical removal, radiotherapy, and chemotherapy. Although these methods were effective, they came with significant drawbacks such as drug side effects and the risk of recurrence.
Since the 1990s, mRNA vaccines have been considered therapeutic vaccines. During the COVID-19 pandemic in 2020, mRNA vaccines were used in clinical treatments, saving countless lives. Today, as the advantages of mRNA vaccines are gradually being discovered, they are now applied in multiple fields.
The advent of China’s first self-replicating mRNA vaccine JCXH-211 undoubtedly marks a new breakthrough in the clinical diagnosis and treatment of various solid tumors in China.
**What is the mRNA Vaccine JCXH-211?**
JCXH-211 is the world’s first self-replicating RNA drug encoding human interleukin-12 (IL-12) to enter clinical trials. This srRNA vaccine delivers mRNA encoding IL-12 into the cytoplasm, continuously expressing IL-12 to enhance the body’s immune response against tumor cells.
In preclinical studies involving various mouse and PDX disease models, JCXH-211 has shown the ability to effectively kill tumor cells, eliminate distant tumors, and prevent tumor recurrence. Comprehensive GLP toxicology studies have also demonstrated good safety.
JCXH-211 has a broad range of indications and is expected to effectively treat multiple solid tumors. The anticipated prospects are as follows:
**1. Lung Cancer:**
As one of the leading causes of cancer death worldwide, lung cancer is often diagnosed at a late stage due to difficulties in early detection. JCXH-211, through continuous expression of IL-12 and activation of immune cells, is expected to effectively control the growth and spread of lung cancer cells.
**2. Colorectal Cancer:**
Current clinical treatments for colorectal cancer primarily involve surgery and radiotherapy/chemotherapy, which can remove visible tumors but have a high recurrence rate. Periodic administration of JCXH-211 may significantly reduce recurrence and improve patient survival.
**3. Soft Tissue/Chondrosarcoma:**
These tumors are highly invasive and cover a wide range of areas, often affecting surrounding soft tissues and progressing rapidly. Current treatments are limited to surgery and radiotherapy/chemotherapy, which, although somewhat effective, are not thorough, leading to high recurrence rates. JCXH-211 could become a new treatment method, enhancing the body’s immune response to combat these stubborn cancer cells.
**4. Skin Cancer:**
Clinical treatments for skin cancer mainly include surgery and radiotherapy. While most skin cancers have a good prognosis, the effects on intractable melanoma are poor. The expression of IL-12 can activate specific T cells, greatly aiding in the elimination of melanoma cells.
**High-Efficiency Activation and Safety of the mRNA Vaccine JCXH-211!**
mRNA vaccines not only encode antigens to induce specific immune responses against tumors but also possess inherent immunostimulatory properties. This dual mechanism allows JCXH-211 to activate the immune system more efficiently, enhancing the overall anti-tumor effect.
Moreover, the safety of mRNA vaccines is well-recognized. Since DNA is the genetic material of most species, including humans and viruses, and is transcribed into mRNA before being translated into proteins to perform functions in the body, injecting mRNA into the human body does not enter the cell nucleus, thereby eliminating the risk of genomic insertion mutations. Additionally, mRNA can be naturally degraded and excreted from the body, preventing accumulation. Thus, JCXH-211 presents lower potential risks and is safer.
Currently, clinical trials are progressing steadily. With the rapid advancement of tumor immunotherapy, JCXH-211 is expected to become a standard treatment for various solid tumors, offering hope to many cancer patients.
