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