Daybue: how long were the pivotal tox studies?

trofinetide · IGF-1 tripeptide analogue

Longest pivotal study

39 (39-week dog)

“The toxicity of trofinetide was tested in Sprague Dawley rat (4- and 26-week) and beagle dog (39-week); trofinetide was administered by oral gavage.”

Pivotal GLP studies

26-week juvenile rat and 39-week juvenile dog oral gavage studies

“The 26- and 39-week studies were conducted in juvenile animals; dosing was initiated at 2 weeks (postnatal days 13-14) and 5- 6 months of age, respectively.”
