Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Guanfacine | Participants will be administered extended-release guanfacine, which is in tablet form, and will be instructed to take the medication once daily for 6 weeks. The daily dose will range between 1 and 4 mg.~Guanfacine: Participants will meet with the study doctor on a weekly basis during the treatment phase of the study. In the first few weeks, the daily dose of the medication will be individually adjusted by the study doctor according to participants' clinical response to and tolerability of the medication. The optimal dose will then be maintained for the remainder of the treatment period. | 0 | 5 | EG000 |
| Group 2 | Lisdexamfetamine | Participants will be administered lisdexamfetamine, which is in tablet form, and will be instructed to take the medication daily for 6 weeks. The daily dose will range between 30 and 70mg.~Lisdexamfetamine: Participants will meet with the study doctor on a weekly basis during the treatment phase of the study. In the first few weeks, the daily dose of the medication will be individually adjusted by the study doctor according to participants' clinical response to and tolerability of the medication. The optimal dose will then be maintained for the remainder of the treatment period. | 0 | 4 | EG001 |
