We understand the importance of clear, accurate, and trustworthy information when making critical healthcare decisions, and we're here to provide an expert perspective on this life-changing treatment.

Is CAR-T Therapy for Non-Hodgkin Lymphoma Approved in China?

China has made significant strides in the approval and availability of CAR-T cell therapies. The NMPA has granted marketing authorization to several CAR-T products for Non-Hodgkin Lymphoma, particularly for relapsed or refractory diffuse large B-cell lymphoma (DLBCL), a common subtype of NHL.

These approvals underscore China's commitment to advancing innovative cancer treatments and making them accessible to patients within the country and, increasingly, to those seeking treatment from abroad.

The first CAR-T therapy approved in China was Axicabtagene Ciloleucel (Axi-cel), developed by Fosun Kite, a joint venture between Fosun Pharma and Kite Pharma (Gilead Sciences).

This was closely followed by the approval of Relmacabtagene Autoleucel (Relma-cel), developed by JW Therapeutics, a joint venture between WuXi AppTec and Juno Therapeutics (Bristol Myers Squibb). These approvals have opened new doors for patients who have exhausted traditional treatment options, offering hope and significantly improved outcomes.

What Specific CAR-T Therapies are Approved in China for NHL?

These two prominent CAR-T therapies, Axi-cel and Relma-cel, have become cornerstones in the treatment of relapsed or refractory DLBCL in China. They operate by genetically engineering a patient's own T-cells to express a chimeric antigen receptor that specifically recognizes and binds to the CD19 protein found on lymphoma cells, leading to their destruction.

• Axicabtagene Ciloleucel (Axi-cel): Approved for adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy. It was initially approved in the US and Europe and subsequently by the NMPA in China.
• Relmacabtagene Autoleucel (Relma-cel): Approved for adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy. Relma-cel is notable as it was developed specifically for the Chinese market, demonstrating local innovation and expertise.

Beyond these, China also has a robust pipeline of other CAR-T therapies undergoing clinical trials, exploring different targets and indications, indicating a dynamic and evolving treatment landscape.

How Effective is CAR-T Therapy for Non-Hodgkin Lymphoma?

The effectiveness of CAR-T therapy for Non-Hodgkin Lymphoma, particularly DLBCL, has been a game-changer. Clinical trials have shown impressive response rates, with a significant number of patients achieving complete remission, meaning all signs of cancer disappear.

For patients who have undergone multiple rounds of chemotherapy and other treatments without success, CAR-T therapy offers a new chance at long-term remission or even a cure.

While results can vary among individuals, studies have consistently reported durable responses. For example, in trials leading to the approval of Axi-cel and Relma-cel, complete response rates were often observed in the range of 50-60% or higher, with many patients maintaining remission for several years.

This sustained response is crucial, as it indicates a potential for a cure rather than just temporary control of the disease. The clinical data from Chinese trials largely mirrors the positive outcomes seen in international studies, reinforcing the therapy's global efficacy.

What are the Eligibility Criteria for CAR-T Therapy in China?

The eligibility criteria for CAR-T therapy are stringent to ensure patient safety and maximize the chances of a successful outcome. Doctors assess several factors before recommending this advanced treatment. Key criteria include:

• Diagnosis: Confirmed diagnosis of specific types of Non-Hodgkin Lymphoma, most commonly relapsed or refractory DLBCL, primary mediastinal large B-cell lymphoma, or high-grade B-cell lymphoma, with CD19 expression on cancer cells.
• Prior Treatment Failure: Patients must have failed at least two previous lines of systemic therapy, such as chemotherapy and radiation, indicating the advanced and resistant nature of their disease.
• Overall Health: Good general health, including adequate organ function (heart, lung, kidney, liver), and a suitable performance status (e.g., ECOG score of 0 or 1). Patients must be able to withstand the potential side effects of the therapy.
• No Active Infections or Autoimmune Diseases: Patients should not have severe active infections or uncontrolled autoimmune conditions.
• Age: While there isn't a strict upper age limit, the patient's overall health and ability to tolerate treatment are more critical than their chronological age.

A comprehensive evaluation by an experienced CAR-T treatment team is essential to determine suitability.

What are the Potential Side Effects of CAR-T Therapy?

While CAR-T therapy offers remarkable benefits, it can also lead to serious side effects due to the powerful immune response it generates. The most common and well-known side effects include:

• Cytokine Release Syndrome (CRS): This is an inflammatory response that occurs when CAR-T cells release large amounts of cytokines into the bloodstream. Symptoms can range from mild (fever, fatigue, headache, muscle aches) to severe (hypotension, hypoxia, organ dysfunction). It typically occurs within the first two weeks post-infusion.
• Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS): Neurological side effects can include confusion, language difficulties, tremors, seizures, and even cerebral edema in severe cases. These symptoms usually appear after CRS has resolved or simultaneously.
• Other Side Effects: These can include low blood counts (cytopenias), infections, hypogammaglobulinemia (low levels of antibodies, increasing infection risk), and tumor lysis syndrome.

Chinese hospitals offering CAR-T therapy are equipped with specialized intensive care units and multidisciplinary teams, including oncologists, neurologists, and critical care specialists, to monitor and manage these potential complications effectively. Management strategies often involve medications like tocilizumab (for CRS) and corticosteroids (for CRS and ICANS).

How Much Does CAR-T Therapy Cost in China for NHL?

The high cost of CAR-T therapy is a global challenge, reflecting the complexity of its manufacturing and personalized nature. In China, while still substantial, the cost can be more accessible compared to regions like the United States or Europe, where prices often exceed $400,000 to $500,000 USD for the therapy itself, excluding hospitalization and supportive care.

The total cost in China encompasses various components:

• CAR-T Product Cost: The price of the manufactured CAR-T cells.
• Hospitalization and Infusion: Costs associated with the initial hospital stay, including monitoring in specialized units (e.g., ICU), and the infusion procedure.
• Pre-conditioning Chemotherapy: The chemotherapy administered before CAR-T infusion to prepare the body.
• Supportive Care and Management of Side Effects: Medications, tests, and care required to manage potential complications like CRS or ICANS.

For Chinese citizens, some local CAR-T products are becoming eligible for partial coverage under certain provincial health insurance schemes or commercial plans, gradually improving accessibility. However, for international patients, the cost is generally out-of-pocket, making it crucial to get a detailed cost estimate from the chosen medical center.

Is Medical Tourism for CAR-T Therapy for NHL Common in China?

China is rapidly gaining recognition as a destination for medical tourism, particularly for cutting-edge treatments like CAR-T therapy. Patients from various parts of Asia, and even some from Western countries, are considering China for several reasons. The primary drivers include:
