The study "Effectiveness and Safety of Sodium-Glucose Cotransporter 2 Inhibitors Added to Dual or Triple Treatment in Patients with Type 2 Diabetes Mellitus," authored by Yesol Hong, Yoomin Jeon, Yoona Choi, Tae Kyu Chung, and Howard Lee, was published in the Diabetes Therapy on December 20, 2023. Conducted at Seoul National University Hospital (SNUH) in South Korea, this research by the CCADD team delved into the use of Sodium-Glucose Cotransporter 2 Inhibitors (SGLT2i) in Type 2 Diabetes Mellitus (T2DM) treatment. The study, utilizing Real-World Data (RWD) from electronic medical records (EMR) from SNUH's a Common Data Model database, revealed improvements in HbA1c levels and a higher rate of patients achieving targeted HbA1c levels with SGLT2i therapy.

Furthermore, CCADD is dedicated to continuing its use of EMR-based RWD to generate important clinical evidence, particularly in areas where Randomized Controlled Trials (RCTs) may face limitations. This commitment underscores CCADD's role in advancing medical research and improving patient care through innovative data utilization.

Yoona Choi and Jung-Hyun Won attended the 65th Annual Meeting & Exposition of the American Society of Hematology (ASH), which took place from December 9 to 12, 2023, in San Diego, USA. Annually, the ASH conference brings together healthcare professionals, researchers, clinicians, and academics from around the globe to explore advancements in hematology. This prestigious event not only focuses on the study, diagnosis, treatment, and prevention of blood disorders but also features a variety of social events and opportunities for collaboration and the sharing of insights among experts in the field. Official photos from ASH are available here.

At the 'Outcomes Research—Lymphoid Malignancies: Poster II' session, Yoona Choi, serving as the first author and representing the entire research team, presented a study titled 'Evaluating the Effectiveness and Safety of Prephase Steroid Treatment before Remission Induction Chemotherapy in Pediatric Acute Lymphoblastic Leukemia: A Common Data Model-Based Real-World Data Approach.' This study investigated steroid pretreatment in pediatric acute lymphoblastic leukemia (ALL) patients undergoing remission induction chemotherapy (RIC), with the aim of reducing complications such as tumor lysis syndrome (TLS). Analyzing data from Seoul National University Hospital and Catholic University Seoul St. Mary’s Hospital, the study compared patients who received steroid pretreatment at least seven days before RIC with those who did not. The findings indicated a significant reduction in TLS incidence in the pretreated group. While overall survival rates were higher in this group, the difference was not statistically significant. These results provide important real-world evidence for the effectiveness of steroid pretreatment in reducing TLS risk in pediatric ALL patients.

This study was part of a larger project, funded by a grant from the Ministry of Health and Welfare, aiming to develop a disease registry database for pediatric ALL using real-world data in the clinical data warehouse (CDW) of Seoul National University Hospital and Catholic University Seoul St. Mary’s Hospital, thereby generating real-world evidence for pediatric ALL.
