In DRIVE-PK, mitapivat was well-tolerated, with mild headache (24 patients), insomnia (22 sufferers), and nausea (21 individuals) becoming probably the most widespread adverse events reported.25 The vast majority of these events resolved within per week of drug initiation. Critical TEAEs felt potentially related to mitapivat occurring in a lot more than one patient incorporated hypertriglyceridemia in four.
