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!

Breakthrough CAR-T Cell Therapy for R/R B-Cell ALL: A Game-Changer in Chinese Medical Innovation

Breakthrough CAR-T Cell Therapy for R/R B-Cell ALL: A Game-Changer in Chinese Medical Innovation
ALL- Acute Lymphoblastic Leukemia
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.
