Real World Evidence
Real-world retrospective study
DYANAVEL XR was associated with reductions in IR supplementation1*†
IR supplementation among participants on DYANAVEL XR1
140 participants did not receive IR supplementation
98%
of 143 participants taking DYANAVEL XR did not receive IR supplementation1
RESULTS PROMPTED AN EXPLORATORY PATH ANALYSIS
Aimed to determine whether the relationship between DYANAVEL XR and reduced IR supplementation at 90 days was explained in part by the relationship between the end-of-dose crash and IR supplementation.1
END-OF-DOSE CRASH FINDING
DYANAVEL XR was shown to reduce end-of-dose crash independent of the association with less IR supplementation. However, end-of-dose crash was not significantly associated with IR supplementation.1
IR supplementation among participants on DYANAVEL XR1
Treatment groups evaluated in this study included1
- DYANAVEL XR (amphetamine), n=143
- Amphetamine ER, n=131 (Adderall XR® n=65 and Vyvanse® n=66)‡
- Methylphenidate ER, n=143 (Concerta® n=53, Focalin XR® n=51, and generic methylphenidate ER n=39)‡
Study assessments and statistical analyses1
- Pre-specified analyses investigated predictors of IR supplementation for patients on ER stimulants
- Further analyses assessed if any factors related to the patient, treatment, side effects, and treatment responses mediated the relationship between DYANAVEL XR use and IR use at 90 days
ER, extended release; IR, immediate release.

methylphenidate preparation) for ≥6 months between November 2022 and June 2024.
