A Chinese medical team has recently made significant progress in t

he field of CAR-T cell therapy, bringing new hope for the treatment of solid tumors such as glioblastoma (GBM). While CAR-T therapy has achieved great success in treating hematologic

al malignancies, its efficacy against solid tumors like glioblastoma remains limited. The innovative research by the Chinese medical team has greatly enhanced the attacking capability of CAR-T cells against solid tumors through the design of high-affinity protein binders from scratch.

The study, published in *Nature Biomedical Engineering* under the title “Targeting overexpressed antigens in glioblastoma via CAR T cells with computationally designed high-affinity protein binders,” presents a novel Binder CAR strategy that replaces the traditional scFv antibody structure. Through computational design, the Chinese research team precisely constructed a new protein binding domain targeting highly expressed antigens in glioblastoma—EGFR and CD276. This new Binder CAR demonstrated significant anti-tumor effects in experiments compared to traditional scFv CAR, especially in the treatment of glioblastoma, a highly malignant tumor. The Binder CAR not only enhanced tumor-killing capacity but also effectively prolonged the survival time of experimental mice.

This groundbreaking technology showcases China’s strong innovative capability in cancer treatment. The Binder CAR can not only identify tumor antigens more stably and efficiently but also reduces the potential T cell exhaustion issues associated with traditional CAR-T therapy, significantly improving treatment durability. In the future, this strategy is expected to be applied to the treatment of other solid tumors, heralding a new era for CAR-T therapy.

China is not only pioneering the era of CAR-T in solid tumors but has also achieved remarkable success in hematological malignancies. Whether it’s the CD19 CAR-T therapy for relapsed or refractory large B-cell lymphoma (DLBCL) and leukemia that is already on the market, or the BCMA CAR-T therapy for multiple myeloma, China has made substantial progress and is now at the forefront of global CAR-T advancements. Additionally, the number of CAR-T therapies in clinical development is astounding, including dual-target CAR-T therapies targeting CD20, CD22, and CD30, or the recently headline-grabbing universal CAR-T therapies, as well as the explosive news regarding CAR-T therapies for autoimmune diseases. China is in a position of complete leadership. We look forward to bringing more good news to cancer patients worldwide.

A groundbreaking CAR-γδT cell therapy, QH104, developed by a Chinese team, is gaining attention in the global medical community for its potential in treating relapsed glioblastoma (rGBM). Targeting B7H3, QH104 is an allogeneic, off-the-shelf therapy with the promise of higher accessibility due to lower production costs compared to autologous cell therapies.

One of the unique strengths of γδT cells is their ability to recognize antigens without MHC restriction, reducing the risk of graft-versus-host disease (GvHD) and making them an ideal candidate for universal cell therapy.

The Phase I clinical trial, a single-center, dose-escalation study, tested QH104 on B7H3-positive rGBM patients who had already completed standard treatments. These patients had a Karnofsky Performance Status (KPS) score of 60 or higher and a minimum life expectancy of three months. The trial followed a “3+3” dose escalation model, with patients receiving intrathecal injections of QH104 once per month.

As of March 30, 2024, seven high-grade rGBM patients (five males, two females, median age 60) had undergone at least one dose of QH104 and were monitored for an average of 6.5 months. The therapy showed an excellent safety profile, with no dose-limiting toxicities. Although minor side effects like fever and headaches were observed, no severe cases of cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), or GvHD occurred. Importantly, QH104 exhibited remarkable efficacy, with an objective response rate (ORR) of 42.9% and a disease control rate (DCR) of 100%, ensuring that all patients saw some level of disease stabilization.

Even more encouraging, 30 days post-treatment, the infused cells were still detectable in patients, indicating the therapy’s persistence. Additionally, a positive correlation between B7H3 expression and clinical outcomes suggests that QH104 could be further personalized to optimize patient selection and treatment protocols in the future.

This pioneering approach marks a significant step forward in CAR-γδT therapy, offering hope for patients with relapsed glioblastoma.
