Global First: Chinese CAR-T Therapy Simultaneously Cures Tumor and Lupus Erythematosus

China make advanced medical treatment affordable

Wang Fang (pseudonym), residing in Yichang, Hubei, China, underwent a life-threatening ordeal. This patient in her forties had been suffering from systemic lupus erythematosus for over 20 years. What exacerbated her agony was the excruciating pain in her right leg since June 2019, which forced her into a wheelchair. Local hospital diagnosis revealed an aggressively invasive tumor—diffuse large B-cell lymphoma.
 
In mid-August 2019, Wang Fang followed a relative’s advice and sought treatment at Peking University Shenzhen Hospital (hereinafter referred to as “PKU Shenzhen Hospital”) in Shenzhen, where she was fortunate to participate in clinical trials for blood tumors. In mid-September 2019, she underwent the compound dual-target CAR-T (CD19/BCMA) cell immunotherapy.
 
Miraculous changes occurred a month after treatment; her lymphoma vanished entirely. Two months later, she was freed from the wheelchair and could walk independently. The nine-month follow-up, more astonishingly, revealed not only the complete disappearance of lymphoma but also the reversal of her long-standing stubborn lupus erythematosus antibodies, signifying her clinical cure from lupus.
 
This is the first documented instance globally where compound dual-target CAR-T cell immunotherapy cured diffuse large B-cell lymphoma and refractory lupus erythematosus—a significant breakthrough in Shenzhen’s oncology clinical research and treatment field.
 
This patient, originally from another region, had relied on steroids and other drugs to manage her condition for over 20 years due to systemic lupus erythematosus. However, the intensified pain in her right leg in June 2019 led to the diagnosis of an invasive tumor, rapidly deteriorating her condition and confining her to a wheelchair.
 
When faced with chemotherapy recommendations at the local hospital, Wang Fang declined due to the side effects she had previously experienced. Fortunately, a relative’s recommendation brought her to PKU Shenzhen Hospital. With the doctors’ dedicated assistance, Wang Fang participated in the clinical trial of CAR-T cell immunotherapy.
 
CAR-T cell therapy is an advanced treatment method that transforms a patient’s own T cells into CAR-T cells capable of identifying and attacking tumor cells. Since its successful treatment of the first case of acute lymphoblastic leukemia in the United States in 2012, this treatment has gradually become a groundbreaking technology in the field of tumor therapy. The Blood Department of PKU Shenzhen Hospital, as a pioneer, has completed over 30 cases of CAR-T cell therapy clinical trials, offering hope for those patients in critical conditions with ineffective traditional treatments.
 
Considering the uniqueness of Wang Fang’s disease, the team designed a compound dual-target CAR-T cell immunotherapy targeting both CD19 and BCMA. The success of this advanced therapy made Wang Fang the first case globally to be cured of lupus erythematosus using CAR-T cell therapy.
 
One month after treatment, she no longer needed wheelchair assistance; two months later, she could walk independently; and nine months later, besides the complete eradication of the tumor, the lupus erythematosus-related antibodies turned negative, leading to her clinical cure without relying on medication for her daily life.
 
Director Zhang Hongyu from the Blood Department of PKU Shenzhen Hospital stated that this successful case marks a significant breakthrough in CAR-T cell therapy, offering the possibility of cure to more patients. This successful clinical trial was also reported at the 61st American Society of Hematology (ASH) Annual Meeting, highlighting PKU Shenzhen Hospital’s significant contributions to the medical field.
 
After enduring this arduous battle, Wang Fang has regained her health and freedom. She expresses gratitude for the exceptional skills and selfless assistance of the medical team at PKU Shenzhen Hospital. Currently, for nine months, she has not taken any medication, regaining her beautiful hair and radiating vitality, looking forward to the future.
 
The appearance of this successful case brings hope and inspiration to the global medical community, showcasing the potential of CAR-T cell therapy in continuous exploration. The Blood Department team at PKU Shenzhen Hospital intends to continue exploring more effective and safer treatment approaches, bringing more hope for patients.

Unveiling Hope: Chinese CAR-T Cell Therapy Illuminating New Paths in Liver Cancer Treatment!

2020, over 19.3 million people were diagnosed with cancer worldwide, leading to almost 10 million fatalities. In China alone, the number of new cancer patients reached a staggering 4.57 million, accounting for 23.7% globally. Liver cancer, among the most prevalent malignant tumors in China, witnessed 410,000 new cases and 380,000 deaths, making up 45.3% and 47.1% of the global total, respectively [1]. However, since the 21st century began, significant strides have been made in liver cancer treatments, particularly in medication and localized therapies. Surgical procedures are no longer the sole option for long-term survival among liver cancer patients.

Immunotherapy has emerged as one of the most promising techniques for treating liver cancer, especially with advancements in tumor molecular biology. In 2013, “Science” magazine categorized immunotherapy as the fourth major cancer treatment, following surgery, chemotherapy, and radiation therapy, with cell therapy becoming a focal point of basic and clinical research in recent years.

In May 2020, Professor Zhai Bo’s team from Shanghai Jiao Tong University School of Medicine’s Renji Hospital, in collaboration with Shanghai Sci-Tech Biotechnology’s team led by Li Zonghai, published groundbreaking preliminary clinical research data on CAR-T cell therapy targeting the GPC3 gene for hepatocellular carcinoma in the “Clinical Cancer Research” journal. This breakthrough study brought unprecedented hope for CAR-T cell therapy in liver cancer treatment.

Even more inspiring, their publication in the “Cancer Communications” journal showcased follow-up results of two late-stage liver cancer patients who achieved long-term tumor-free survival after receiving CAR-T cell combined with local therapy [2]. These findings shed new light on the treatment prospects for liver cancer patients.

However, despite the potential therapeutic effects of liver cancer CAR-T cell therapy, it faces challenges and obstacles. Liver cancer’s heterogeneity, tumor microenvironment, and the safety of cell therapy remain crucial issues to address.

Presently, revolutionary changes are underway in the treatment models and concepts for liver cancer. However, integrating CAR-T cell therapy into actual liver cancer treatment requires further scientific exploration and clinical research. Researchers emphasize that only through comprehensive utilization of CAR-T cells in conjunction with other treatment modalities can its therapeutic potential be fully realized.

Professor Zhai Bo’s team is currently conducting various fundamental and clinical studies aimed at exploring additional possibilities for CAR-T cell therapy in solid tumors. These studies include phase I clinical research on EpCAM CAR-T cell combined with ablative therapy for gastrointestinal tumors, phase II clinical research on Claudin18.2 CAR-T cell therapy for gastrointestinal tumors, studies on the mechanism and prevention of OTOT toxicity, among others. These endeavors will provide more experimental data and support for the application of CAR-T cells in the treatment of solid tumors.

In conclusion, liver cancer CAR-T cell therapy signifies a significant breakthrough in the field of liver cancer treatment, offering new hope for patients. Despite the challenges to overcome, the outlook for this therapy is promising and holds the potential to bring a blessing to more patients in the future.

The new hope for pediatric patients with relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL) boasts an overall survival rate of up to 96%.

The new hope for pediatric patients with relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL) boasts an overall survival rate of up to 96%.
    Recently, CAR-T cell therapy targeting B-cell malignancies has encountered a series of inquiries and challenges, particularly concerning discussions on CAR-T cell-related toxicity, resistance, antigen escape, and limitations in persistence. However, a groundbreaking concept addressing relapse in patients after CAR-T cell therapy has been introduced for the first time: a sequential approach involving distinct targeted CAR-T cell therapies.
    Within this approach, CD19 CAR-T cell therapy has demonstrated the ability to achieve complete remission in 60% to 90% of relapsed or refractory acute B-cell lymphoblastic leukemia patients. By experimenting with different combinations and sequential administration strategies of B-cell antigen-targeted CAR-T cell therapies, there’s potential to prevent tumor antigen escape and prolong the persistence of CAR-T cells.
    Preliminary clinical trials have provided initial support for this concept, notably a phase II clinical trial aimed at assessing the efficacy of sequential CD19 and CD22 CAR-T cell therapy. Its findings revealed a 79% event-free survival rate, an 80% sustained remission rate, and an impressive 96% overall survival rate among patients receiving targeted doses in sequential therapy. Encouragingly, the overall safety of this sequential therapy appeared manageable, providing long-term survival benefits for children with relapsed or refractory acute B-cell lymphoblastic leukemia.
However, the limitations of antigen escape and limited persistence after CAR-T cell therapy persist. Addressing these challenges, researchers have proposed the hypothesis of sequential administration of CAR-T cell products targeting different antigens, aiming to maintain the persistence of CAR-T cells.
    The results of this phase II clinical trial indicate that administering CD22 CAR-T cell therapy following CD19 CAR-T cell infusion can result in longer-lasting remission effects for pediatric patients with relapsed or refractory B-cell acute lymphoblastic leukemia, achieving an 80% sustained remission rate over 18 months and an impressive 96% overall survival rate. Importantly, the overall safety of this sequential therapy is uplifting, providing long-term survival benefits for this specific patient population.
    In summary, this study presents groundbreaking evidence for new strategies and directions in CAR-T cell therapy. Despite existing limitations, this therapy demonstrates significant potential in treating uncontrollable acute B-cell lymphoblastic leukemia, potentially offering more enduring treatment effects and long-term survival benefits for these patients. This achievement points towards a viable path for the future development of cell therapies.
    This Phase 2 trial, conducted at Beijing GoBroad Boren Hospital in China, enrolled pediatric patients aged 1–18 years diagnosed with relapsed or refractory B-cell acute lymphocytic leukaemia (ALL) showing CD19 and CD22 positivity exceeding 95%.

If a child unfortunately gets leukemia, should CAR-T Therapy be considered?

In recent years, CAR-T therapy has gained traction in treating leukemia. A quick search yields numerous articles, many of which describe the miraculous effects of CAR-T.
Is the efficacy of CAR-T therapy really that impressive? Should CAR-T therapy be considered for a child diagnosed with leukemia? Today, let’s unravel these doubts together!
What kind of leukemia patients can undergo CAR-T therapy?
Since most acute leukemia patients are sensitive to chemotherapy, chemotherapy is the preferred initial treatment. Currently, CAR-T therapy is primarily used for refractory and relapsed acute B-cell lymphoblastic leukemia patients.
For cases where 1-2 courses of chemotherapy fail to achieve complete remission (primary refractory), or relapse during chemotherapy, or experience ineffective re-treatment after relapse and re-chemotherapy (refractory relapse), CAR-T therapy is the preferred approach.

Breakthrough medical research in China brings hope for multiple myeloma patients.

Eque-cel brings new treatment prospects for multiple myeloma.

    From December 9th to 12th, the Annual American Society of Hematology Meeting (ASH 2023) was held in San Diego, USA. At this conference, the FUMANBA-1 study, led by Professors Chunrui Li from Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, and Lugui Qiu from the Institute of Hematology, Chinese Academy of Medical Sciences, conducted at 14 medical centers nationwide, demonstrated the efficacy and characteristics of sustained minimal residual disease (MRD) negativity in multiple myeloma (MM) patients treated with Eque-cel injection (CT103A). Their achievements were included in the oral presentation at the conference.

Current MM Treatment and Challenges of CAR-T Therapy CAR-T cell therapy holds significant importance in the treatment of multiple myeloma, overcoming patients’ immunodeficiency and tolerance issues. Currently, China has approved three CAR-T cell drugs targeting multiple myeloma. Compared to traditional treatments, CAR-T cell therapy enhances immune function without relying on the major histocompatibility complex (MHC), improving the activity of NK cells, T cells, and B cells while effectively activating T cells. However, despite significant advancements in CAR-T cell therapy in the MM field, some patients still struggle to maintain treatment effectiveness, leading to potential relapses, with antigen escape being one of the important mechanisms causing relapse.

Furthermore, the safety of CAR-T therapy is a major concern, including adverse reactions such as cytokine release syndrome (CRS), neurotoxicity, infections, B cell depletion, and hypogammaglobulinemia. Hence, monitoring patient indicators throughout the entire CAR-T treatment process, from pre-treatment to infusion, is crucial for timely intervention in adverse reactions.

    100% MRD Negativity Rate for CR and Above Patients! Eque-cel Injection Brings Redemption for Multiple Myeloma

    Eque-cel injection (CT103A) is a fully humanized CAR-T cell therapy drug targeting B cell maturation antigen (BCMA), approved by the National Medical Products Administration (NMPA) for adult refractory/relapsed multiple myeloma patients in China. In the Phase II FUMANBA-1 study, this treatment showed significant and sustained efficacy.

As of December 31, 2022, with a median follow-up time of 18.07 months, deep and sustained remissions were observed in 103 evaluable patients. The overall response rate (ORR) among these 103 patients was 96.1%, with a strict complete response (sCR)/complete response (CR) rate of 77.7%. Among 91 subjects with no previous CAR-T treatment history, the ORR was 98.9%, and the sCR/CR rate reached 82.4%, with a 12-month progression-free survival (PFS) rate of 85.5%.

The minimal residual disease (MRD) negativity rate for the entire population was 94.2%, reaching 100% for CR and above patients. The median time to MRD negativity was 15 days, and 80.8% of patients maintained MRD negativity 12 months post-infusion. Moreover, the Eque-cel injection exhibited a relatively long median persistence in the body, lasting up to 307.5 days.

According to Professor Chunrui Li, “The sustained MRD-negative status is closely related to the improvement in PFS of patients receiving Eque-cel treatment.”

Professor Chunrui Li’s team studied the characteristics of patients maintaining MRD negativity for ≥6 months and ≥12 months in the FUMANBA-1 study. The research revealed that among 88 patients achieving MRD negativity, 78.4% maintained MRD negativity for at least 6 months, and 74.4% sustained MRD negativity for at least 12 months. Patients with sustained MRD negativity showed longer…
