Observational analysis showed OTS167 improved erythropoiesis in Diamond Blackfan Anemia models, suggesting novel approaches to anemia treatment.

OTS167 treatment improved erythropoiesis by enhancing early-stage precursors in DBA models.
In vivo, treated Rpl11wt/LoxpCre-Ert2 mice maintained hemoglobin levels during 9 months with significance differences observed.
Analysis using bulk RNA-seq revealed OTS167 downregulates NUPR1, impacting hematopoietic stem cell proliferation.
These findings support the potential of NLK inhibitors like OTS167 as novel therapeutic options for DBA patients.

Nair et al. (2025) studied this question.
