In recent years, China has made significant progress in medical innovation, especially in the field of Chimeric Antigen Receptor T-cell (CAR-T) therapy, dramatically changing the landscape of treatment for malignant blood cancers. Recently, a team of medical professors from Zhejiang, China, released the results of a clinical trial demonstrating the breakthrough effectiveness of fourth-generation anti-CD19 CAR-T cell therapy for patients with relapsed/refractory large B-cell lymphoma (R/R LBCL). The study, published in the renowned journal *Cell Discovery* (“Safety and feasibility of anti-CD19 CAR T cells expressing inducible IL-7 and CCL19 in patients with relapsed or refractory large B-cell lymphoma”), sheds light on this innovative approach.

**New Highlights of CAR-T Therapy**

Traditional anti-CD19 CAR-T cell therapy has already shown excellent efficacy in treating blood cancers like R/R LBCL, but tumor relapse remains a significant challenge. To address this, Chinese researchers have developed a new fourth-generation CAR-T cell therapy that co-expresses two cytokines, IL-7 and CCL19. These cytokines enhance the activity of immune cells, improving CAR-T cells’ anti-tumor effects and extending patient survival.

**Efficacy and Potential**

The Chinese medical team included 39 patients, aged 29 to 73, in this study. They received a single infusion of the fourth-generation anti-CD19 CAR-T cells co-expressing IL-7/CCL19. The results showed that within three months of treatment, the overall response rate (ORR) reached 79.5%, with a complete response rate (CR) of 56.4%. This therapy also demonstrated a notable long-lasting effect, with a median progression-free survival (PFS) of 13 months, and an estimated two-year overall survival rate (OS) of 53.8%.

The study found that the expansion of CAR-T cells in the blood and plasma levels of IL-7/CCL19 were closely associated with clinical outcomes. Higher CAR-T cell expansion and peak concentrations of IL-7/CCL19 were linked to better overall survival (OS), further confirming that this combination can enhance CAR-T cells’ anti-tumor potential.

**Why Is This Study So Important?**

The introduction of this new CAR-T therapy in China marks a significant leap forward in cancer treatment. It not only induces long-lasting remission but also significantly extends patient survival, with manageable safety, offering new hope to patients facing resistant blood cancers. China’s rapid advancements in CAR-T technology showcase its growing influence in the global biotechnology sector.

This groundbreaking research not only solidifies China’s important position in medical innovation but also lays the foundation for future development and application of more CAR-T therapies, potentially bringing revolutionary changes to cancer treatment worldwide.

China Leads the CAR-T Therapy Revolution, Reshaping the Treatment Landscape of Large B-Cell Lymphoma—2024 CSCO Annual Meeting

At the 27th Annual Chinese Society of Clinical Oncology (CSCO) Conference, held in Xiamen, China, CAR-T therapy took center stage as a key focus for the treatment of large B-cell lymphoma (LBCL). As a Chimeric Antigen Receptor T-cell (CAR-T) therapy, this innovative approach is revolutionizing the treatment of relapsed/refractory large B-cell lymphoma (R/R LBCL), offering new hope for patients where traditional therapies have been less effective.

### Breakthroughs in CAR-T Therapy for LBCL

As a major innovation in immunotherapy, CAR-T therapy has shown remarkable efficacy in treating R/R LBCL. Clinical data indicates that about one-third of R/R LBCL patients can achieve long-term remission or even cure through CAR-T therapy. Notably, Axicabtagene ciloleucel (Axi-cel), developed by Fosun Kite Biotechnology, is the first domestically approved CD19-targeted autologous CAR-T product in China. Six-year follow-up results revealed that the two-year overall survival rate was 50.5%, and the six-year lymphoma event-free survival rate was 33.5%.

Meanwhile, Relma-cel, a CAR-T product independently developed by JW Therapeutics in China, has also achieved impressive results. Two-year follow-up data showed a median duration of response of 20.3 months, further highlighting China’s growing research and manufacturing strength in the CAR-T therapy field.

### CAR-T Therapy Expands from Third-Line to Second-Line Use

While CAR-T therapy was initially used only for patients who had failed multiple lines of treatment, it is now being increasingly applied in second-line settings. Recent studies have shown that CAR-T therapy outperforms traditional high-dose chemotherapy and autologous stem cell transplant (ASCT) in certain patient groups. For example, the ZUMA-7 study demonstrated that Axi-cel significantly improved event-free survival (EFS) for LBCL patients treated in the second-line setting, with a median EFS of 8.3 months, compared to 2 months in the ASCT group.

As more research progresses, CAR-T therapy has been recommended by leading clinical guidelines, such as the National Comprehensive Cancer Network (NCCN), for use in patients with primary refractory or early relapsing LBCL. This shift underscores CAR-T’s growing role in earlier stages of treatment, providing more therapeutic options for patients.

### Challenges and Future Prospects

In the exploration of CAR-T as a first-line treatment, promising results are beginning to emerge. The ZUMA-12 study evaluated the use of Axi-cel in high-risk LBCL patients in the first-line setting, with a three-year follow-up showing an overall survival rate of 90.6%. These findings suggest that CAR-T therapy could become an important treatment option for high-risk patients even in the first-line setting.

### China’s Leading Role in CAR-T Therapy

China is rapidly emerging as a global leader in the development and commercialization of CAR-T therapy. With domestically developed products like Axi-cel and Relma-cel achieving significant progress both in China and globally, China’s competitive edge in this field is becoming increasingly evident. As the technology matures and more clinical data are released, the future of CAR-T therapy in LBCL treatment looks exceptionally bright.

The 2024 CSCO Annual Meeting showcased China’s strong commitment to advancing CAR-T therapy. As breakthroughs and challenges coexist, CAR-T therapy is poised to continue playing a critical role in the treatment of large B-cell lymphoma, with China leading the way in this global medical revolution.
