Taiho Oncology and Astex Pharmaceuticals Announce Data Presentations at the 65th ASH Annual Meeting

  • Real-world evidence on use of oral decitabine and cedazuridine in the treatment of myelodysplastic syndromes to be featured in an oral presentation; results of several additional studies in hematological malignancies were accepted for poster presentations

Princeton, N.J., and Pleasanton, Calif., November 17, 2023 – Taiho Oncology Inc. and Astex Pharmaceuticals, Inc. announced today details of studies to be presented at the 65th American Society of Hematology (ASH) Annual Meeting, to be held Dec. 9-12, 2023, in San Diego. Among these data are the results of a real-world study of oral decitabine and cedazuridine in patients with myelodysplastic syndromes (MDS), which will be featured in an oral presentation.

“Real-world data in healthcare is invaluable as it provides us with a closer look at actual patient experiences outside the clinical trial setting,” said Tehseen Salimi, MD, MHA, Senior Vice President Medical Affairs, Taiho Oncology. “This study is the first to explore how an oral therapy may help patients with MDS adhere to their treatment regimen, while reducing both personal and disease burden. Oral decitabine and cedazuridine is a potentially important treatment option for people living with this form of cancer.”
