Datasheet of GBT-440
Description: GBT440 is a novel small molecule hemoglobin modifier which increases hemoglobin oxygen affinity. In vitro and in vivo studies have shown it to be a potent and direct anti-sickling agent with high specificity for hemoglobin, and that 10-30% hemoglobin modification could be both safe (not compromising oxygen delivery) and effective (preventing HbS polymerization).Single, oral, daily dosing with GBT440 was well tolerated across a wide dose range and demonstrated dose proportional and predictable PK and PD. GBT440 demonstrated proof of mechanism with a dose-dependent increase in hemoglobin oxygen affinity without causing tissue hypoxia. GBT440 demonstrated proof of concept in SCD patients with rapid reduction in RBC hemolysis and improved oxygen delivery to tissues as evidenced by reduced erythropoietin level, and a marked reduction in circulating sickle cells.
