Recently, a collaborative research study conducted by multiple Chinese medical and research institutions was published in *Nature Medicine*. This study, titled “Allogeneic CD5-specific CAR-T Therapy for Relapsed/Refractory T-ALL: A Phase 1 Trial,” demonstrated the potential of CD5 CAR-T cells in treating relapsed/refractory acute T-cell lymphoblastic leukemia (R/R T-ALL).

### Innovative Therapy Brings Hope

For a long time, patients with relapsed/refractory T-ALL have lacked effective treatment options and faced a poor prognosis. In recent years, CD7 CAR-T cell therapy has shown some efficacy in these patients, but CD7-negative relapse remains a significant challenge. This study focuses on evaluating the safety, efficacy, and pharmacokinetics of CD5 CAR-T cells, offering new insights for future treatments.

The study included 19 patients, most of whom had previously received CD7 CAR-T therapy. Results showed that this therapy was safe, with no dose-limiting toxicity observed, and adverse events were primarily manageable hematologic toxicity. In terms of efficacy, all patients achieved complete remission within 30 days of treatment. The study also demonstrated, for the first time, the persistence of CD5 CAR-T cells in the body and their ability to eliminate CD5+ T cells, indicating strong anti-tumor activity.

### Breakthrough in Treating Relapsed Patients

In addition to safety and efficacy, the research team explored the coexistence of CD7 CAR-T and CD5 CAR-T cells and studied immune cell changes in the patients. For those who relapsed after CD7 CAR-T treatment with CD7-negative cells, CD5 CAR-T offered a new salvage therapy, providing additional treatment options for such patients.

### Multidisciplinary Collaboration Drives Clinical Progress

Unlike CAR-T therapies for B-cell tumors, treating T-cell malignancies poses more challenges, particularly in controlling immune deficiencies. Dr. Jing Pan and her team conducted in-depth research on target selection and relapse mechanisms, while also focusing on balancing treatment safety and efficacy.

This study was made possible by the collaborative efforts of various medical institutions in China, collectively opening up a new therapeutic pathway for T-cell tumor patients.

### Looking Ahead

As innovations and advances in T-ALL treatment continue, the team plans to further research CD5 CAR-T therapy and collaborate with experts across various fields to optimize CAR-T treatment protocols, helping more patients with T-cell lymphoblastic tumors overcome their diseases.

This series of research achievements not only brings new hope to patients with R/R T-ALL but also provides valuable insights for the future development and optimization of CAR-T therapies. The team remains committed to a patient-centered approach, striving to drive continuous breakthroughs and innovations in T-cell tumor treatment.

CAR-T therapy has reached another breakthrough with the introduction of ssCART-19, a new treatment that leverages IL-6 gene silencing technology to significantly reduce side effects, particularly when treating relapsed/refractory acute lymphoblastic leukemia (r/r ALL). Unlike traditional CAR-T therapies, ssCART-19 drastically lowers the risks of severe cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS).

In the latest clinical trials, ssCART-19 demonstrated outstanding safety, with no patients experiencing ICANS, marking a milestone in CAR-T therapy safety. Among the 17 patients treated, 58.8% showed a significant increase in cell counts, and no cases of Grade 4 or higher CRS were reported. Additionally, ssCART-19 achieved an overall response rate (ORR) of 87.5% within three months, with nearly 63% of patients reaching complete remission.

The latest research also highlights that ssCART-19 outperforms traditional CAR-T products (cCART-19) in both safety and efficacy. Compared to conventional therapies, ssCART-19 significantly reduced the incidence of severe CRS, neutropenia, and ICANS, achieving an ORR of 91.5%. With these impressive results, ssCART-19 is expected to become a groundbreaking option for treating r/r ALL, offering new hope, especially for patients with central nervous system leukemia (CNSL).

Developed by a Chinese biopharmaceutical company, ssCART-19 has gained widespread recognition on the international stage, receiving Orphan Drug designation from the U.S. FDA and being listed as a breakthrough therapy in China. ssCART-19 offers a new treatment option for patients previously excluded from CAR-T therapy, greatly enhancing their chances of survival.

Stay tuned for more updates on how ssCART-19 is transforming cancer immunotherapy.

Haematologica Spotlight：A Chinese team published the largest-scale pediatric-style regimen treatment for adult Ph-negative ALL

🔬 *Haematologica Spotlight* 🔬

A Chinese team published the largest-scale pediatric-style regimen treatment for adult Ph-negative ALL

Acute Lymphoblastic Leukemia (ALL)

    is a hematological malignancy characterized by the proliferation of immature lymphoid cells in the bone marrow, peripheral blood, and extramedullary sites. While the prognosis for childhood ALL is relatively favorable, with a 5-year overall survival rate of 80-90%, adult ALL poses greater challenges. Approximately 20-30% of adult acute leukemias are ALL, with about two-thirds being Philadelphia chromosome-negative (Ph-negative) ALL. Conventional adult ALL treatments have shown high remission rates but also high relapse rates and poor long-term survival.

Haematologica

Inspired by the success of pediatric ALL treatments, especially in adolescent and young adult patients, the Hematology Center at the

Chinese Academy of Medical Sciences and Peking Union Medical College Hospital

    embarked on a groundbreaking journey. Their pioneering research, recently published in *Haematologica*, presents the results of the largest prospective cohort study in China investigating the efficacy of a pediatric-inspired regimen in adult Ph-negative ALL patients.

 

The study, led by Dr. Wang Jianxiang and his team,

    evaluated the IH-2014 regimen’s effectiveness in 415 newly diagnosed adult Ph-negative ALL patients treated between April 2014 and December 2021, with a median age of 27 years (range 14-65 years) and a median follow-up of 40.8 months. The overall 5-year overall survival (OS) and disease-free survival (DFS) rates were 53.8% and 51.1%, respectively, with a chemotherapy-related mortality rate of 3.6%.

 

Patients achieving complete remission (CR)

    after induction therapy with available bone marrow minimal residual disease (MRD) data were categorized based on diagnostic risk: standard-risk (SR) MRD-negative (<0.01%) in 73 patients (18.8%), SR MRD-positive (≥0.01%) in 69 patients (17.7%), high-risk (HR) MRD-negative in 120 patients (30.8%), and HR MRD-positive in 127 patients (32.6%). The 5-year OS rates for these groups were 82.6%, 58.7%, 58.3%, and 36.1%, respectively (P＜0.001), with corresponding cumulative relapse rates of 24.2%, 41.1%, 36.3%, and 50.1% (P＜0.001). Multivariate analysis identified age ≥40 years and MRD positivity after induction as independent adverse prognostic factors for OS and DFS.

 

In conclusion, the IH-2014 regimen demonstrates significant efficacy and good tolerability in adult Ph-negative ALL patients, with younger patients (<40 years) benefiting more prominently. Induction treatment response combined with MRD levels serves as a valuable prognostic indicator for long-term survival and relapse, guiding allogeneic hematopoietic stem cell transplantation decisions in patients achieving first complete remission (CR1).

 

This study marks a pivotal milestone in advancing adult ALL treatment strategies, showcasing China’s remarkable progress in the field of hematology. Stay tuned for more groundbreaking research from our team!

The Fourth China Hematology Development Conference – CAR-T Frontier Forum and the First CAR-T Cell Immunotherapy Summit (JCIS), held on January 5, 2024, in Tianjin.

 

Potential Best-in-Class: Inaticabtagene Autoleucel Redefining Long-term Outcomes for R/R B-ALL

 

Professor Ma Jun from the Harbin Institute of Hematology and Oncology shared notable progress in immunotherapy and cell treatment for Chinese ALL. Previously, the overall complete response (CR) rate for adult R/R ALL treatment in China was approximately 40%, with a mere 11% 3-year survival rate. The introduction of CAR-T cell therapy has been a paradigm shift, altering the long-term outcomes for R/R B-ALL patients.

Inaticabtagene Autoleucel demonstrates superior efficacy:

Higher overall response rates (ORR) at 3 months and beyond, with median duration of response (DOR) and overall survival (OS) surpassing other products.

Patients treated with Inaticabtagene Autoleucel exhibit similar long-term benefits in OS, whether or not they undergo subsequent transplantation.

 

Inaticabtagene Autoleucel boasts enhanced safety:

Lower incidence rates of grade 3 cytokine release syndrome (CRS), grade 3 immune effector cell-associated neurotoxicity syndrome (ICANS), and infusion-related mortality compared to other CAR-T products.

 

Moreover, in minimal residual disease-positive (MRD+) B-ALL patients, CAR-T cell therapy has shown significant progress. It eradicates MRD, improves survival rates, and may serve as a first-line consolidation therapy for CR patients, aiding in:

 

Higher remission rates

Reduced transplant requirements, mitigating transplant-related complications

Maintenance of long-term remission for those unsuitable for allo-HSCT or unwilling to undergo it

 

Improved overall survival

Lower intensity and duration of intensive chemotherapy, leading to shorter treatment times and enhanced compliance.

 

The Future Outlook: Believing in the potential of CAR-T cell therapy, it is anticipated that this innovative treatment will extend hope to currently incurable diseases such as solid tumors and brain tumors. The strides made in Chinese medical innovation, exemplified by Inaticabtagene Autoleucel, signal a promising future for the global landscape of CAR-T cell therapy.
