Through its mechanism of action, mitapivat increases adenosine triphosphate, leading to improvements in red blood cell health, ineffective erythropoiesis and haemolysis. An open-label, multicentre, phase 2 study (NCT03692052) is evaluating mitapivat 100 mg twice daily in adults with NTDT. We previously reported a statistically significant haemoglobin response (a ≥1.0 g/dL increase in haemoglobin concentration from baseline at ≥1 assessments between Weeks 4 and 12 [inclusive]) during the 24-week core period. Here, we report efficacy and safety results up to Week 156 and to data cut-off date respectively. Of 20 patients enrolled, 17 continued in the extension period.
