Qelbree Launch Update

The early performance of Qelbree is on track with our expectations. Current trends in prescriptions reflect the heavy sampling programs with patients. Over 25,000 starter kits have been distributed to physicians since the launch and in preparation for the back-to-school season.
Early clinical feedback about the performance of Qelbree in patients is positive and in line with the Phase III clinical results.
