Supply and Demand in the Mathematics of Rare Disease Drug Development: Why Choosing the Right Model Is Crucial

open access: yesClinical and Translational Science, Volume 19, Issue 5, May 2026.
ABSTRACT Clinical trials for rare diseases face a fundamental mathematical challenge that conventional randomized controlled trial (RCT) designs cannot overcome. With approximately 95% of the estimated 10,000–16,000 rare diseases lacking approved therapies, and drug development programs failing at rates exceeding 75% in non‐oncology indications, the ...

Whole Blood Transcriptomic Analysis of Sickle Cell Trait

open access: yesEuropean Journal of Haematology, Volume 116, Issue 5, Page 535-544, May 2026.
ABSTRACT Sickle cell trait (SCT) is the heterozygous carrier state for the HBB missense variant which causes sickle cell disease (SCD). SCT has been associated with increased risk of venous thromboembolism and chronic kidney disease as well as alterations in clinical laboratory parameters. To investigate differential gene expression in SCT, we used RNA
