In the fight against multiple myeloma (MM), the last few decades have seen significant advancements, yet the disease remains notoriously difficult to cure, particularly in patients with relapsed/refractory multiple myeloma (RRMM). These patients face enormous challenges, as their options become increasingly limited after multiple lines of therapy have failed. However, hope has emerged in the form of BCMA CAR-T therapy, offering deep remission and long-term survival for those who had nearly lost hope.

One such case is a 58-year-old woman from Singapore, who after exhausting all available treatments in her home country, found new hope in China`s innovative CAR-T therapy. Diagnosed with MM in May 2021 following a month of severe back pain, she underwent a series of treatments including CD38 monoclonal antibodies, immunomodulatory drugs (IMiDs), proteasome inhibitors (PI), and XPO-1 inhibitors. Unfortunately, these therapies failed to halt the progression of her disease, which had become highly resistant to treatment.

In December 2023, she traveled to Beijing Chaoyang Hospital, Capital Medical University, where Professor Chen Wenming took charge of her case. The patient was diagnosed with high-risk MM (IgG-κ type) and admitted to the hospital on November 25, 2023, for CAR-T therapy.

#### The Treatment Journey: A Detailed Overview

Given the patient’s refractory nature and multiple prior treatments, Professor Chen devised a tailored treatment plan to improve her chances of survival and quality of life. In November 2023, her lymphocytes were collected to prepare the CAR-T cells. During this period, she received two cycles of D-PACE (dexamethasone, cisplatin, doxorubicin, cyclophosphamide, and etoposide) chemotherapy in Singapore to control the extramedullary plasmacytoma.

In February 2024, she returned to Beijing for further evaluation, where her condition was assessed as showing minimal response (MR). She was then administered a lymphodepletion regimen of fludarabine and cyclophosphamide on February 29. The following month, she received a transfusion of BCMA CAR-T cells.

Within five days post-transfusion, the patient developed a fever, which peaked at 39°C. Fortunately, her oxygen saturation and heart rate remained normal, and she was diagnosed with Grade 1 cytokine release syndrome (CRS). After symptomatic treatment, her blood counts recovered by day 15, and she was discharged in stable condition.

Two weeks post-CAR-T therapy, her response was evaluated as a very good partial response (VGPR), and by the two-month mark, her condition had improved to complete remission (CR) with minimal residual disease (MRD) negativity.

#### Insights from Leading Experts

Professor Wee Joo Chng, a specialist in high-risk MM, noted the aggressive nature of the patient’s disease, marked by genetic abnormalities like 1q21+ and t(4;14). Despite the use of multiple potent therapies, including KRd, XVd, and Isa-Pd, the patient’s disease continued to progress rapidly. The emergence of the del(17p) mutation further complicated her prognosis, indicating the need for a novel therapeutic approach.

The FUMANBA-1 study has highlighted the effectiveness of China`s indigenous CAR-T product, Equecabtagene Autoleucel, in achieving deep remission and prolonging survival in RRMM patients. This case demonstrated the therapy`s potential to overcome poor prognostic factors and extend the patient’s survival. Notably, the patient experienced only mild CRS and no immune effector cell-associated neurotoxicity syndrome (ICANS) or infections during treatment. At the two-month follow-up, the patient’s condition had improved to CR with MRD negativity, suggesting that Equecabtagene Autoleucel could be a game-changer for high-risk RRMM patients.

#### A New Frontier in CAR-T Therapy

RRMM patients with double-hit characteristics often experience early relapse and progression, leading to shortened survival times. Traditional therapies, including IMiDs, PIs, and monoclonal antibodies, have failed to overcome these poor prognostic factors, indicating the urgent need for novel treatments. Real-world studies have shown that CAR-T therapy offers comparable progression-free survival (PFS) and overall survival (OS) rates in RRMM patients, regardless of high-risk cytogenetic abnormalities.

The FUMANBA-1 study revealed impressive outcomes for Equecabtagene Autoleucel in RRMM patients, with an overall response rate (ORR) of 98.9% and an MRD negativity rate of 97.8% among CAR-T-naive patients. The CR rate was 82.4%, and 81.7% of patients maintained MRD negativity for over a year.

Globally, four CAR-T products are currently available, and a recent study presented at the 2024 European Society for Blood and Marrow Transplantation (EBMT) compared the short- and long-term efficacy of these therapies. The study’s matching-adjusted indirect comparison (MAIC) analysis revealed that Equecabtagene Autoleucel had a 12-month PFS rate of 94.2%, higher than the 75% observed with Ciltacabtagene autoleucel (CARTITUDE-1 study). Furthermore, the 12-month sustained MRD negativity rate for Equecabtagene Autoleucel was 100%, compared to 53.1% for Ciltacabtagene autoleucel.

These findings suggest that Equecabtagene Autoleucel, a Chinese-developed BCMA CAR-T therapy, offers superior long-term efficacy compared to its U.S. counterpart. As the global community celebrates the first anniversary of its approval, Equecabtagene Autoleucel continues to bring hope to RRMM patients worldwide, further solidifying China’s leading role in the field of cellular therapy.

🌟BCMA (also known as CD269) and GPRC5D, these two targets are revolutionizing the treatment landscape of multiple myeloma (MM). BCMA is one of the hottest targets for treating MM currently, while GPRC5D is poised to be a potent complement to BCMA.

 

🔍 About BCMA: CAR-T Therapy with Remission Rates Exceeding 90%!

 

👩‍⚕️BCMA is primarily expressed on the surface of terminally differentiated B cells, making it a promising new target in hematologic malignancies treatment. Currently, both in clinical trials and marketed BCMA-targeted CAR-T therapies have shown significant efficacy, with some second-generation CAR-T projects achieving remission rates of over 90%, and the remission rates of domestically produced CAR-T products are also leading globally.

 

Among domestically produced CAR-T therapies in China,

🌟The marketed injection of Cilta-cel (Carvykti) has an overall remission rate of 89.6% and a complete remission rate of 77.1%.

🌟The fully human Equecabtagene Autoleucel injection (developed by the highly regarded Chinese company IASO Bio) boasts an overall remission rate of 98.9%, with a complete remission rate of 82.4%.

🌟Additionally, recent follow-up data from the ASH conference showed that Zevor-cel, developed by Chinese company CARsgen and just approved for market in China, has an overall remission rate of 100%, with a complete remission rate of 92.9%.

 

💡 About GPRC5D: A New Hopeful Treatment Target!

 

🔬About 65% of MM patients exhibit high expression of GPRC5D, and its expression is relatively independent of BCMA. The development speed of domestically produced CAR-T projects in China is considerable. For example, OriCAR-017, a CAR-T product developed by a domestic pharmaceutical company, achieved an overall remission rate of 100% in 10 trial patients, with a strict complete remission rate of 60%.

 

🩺China is rapidly advancing in the field of CAR-T therapy, leading the way in both technological development and clinical applications. In the future, we will witness more “miracles of healing” created by these novel cell therapies.
