Hyperactivity in Children With Down Syndrome Impulsivity in Children With Down Syndrome | Drug: Guanfacine Hydrochloride Immediate Release Drug: Placebo | Phase 2 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 60 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Participants will be randomized 2:1 to GIR or placebo. |
Masking: | Triple (Participant, Care Provider, Investigator) |
Masking Description: | A masked investigational pharmacist or designee will dispense study product according to randomization treatment assignments. All other site staff as well as participants and parents/legal guardians will also be masked for up to 8 weeks while the study participant is receiving study product. Participants, parents/legal guardians, site staff, and study administrators will be unmasked at the 8 week study visit. Emergency unmasking may occur at any time throughout the study in the event that knowledge of the actual treatment is absolutely essential for further management of the participant. |

- Change in parent-rated ABC-H (Aberrant Behavior Checklist-Hyperactivity) subscale core [ Time Frame: Baseline to Week 8 ]Change from baseline to Week 8 of the ABC-H subscale score. The ABC-H is a subscale of the ABC. Each of the 16 items is scored as 0 (never a problem), 1 (slight problem), 2 (moderately serious problem), or 3 (severe problem). The total score range is 0 to 48, where a higher score indicates endorsement of greater hyperactivity. Rating based on patient's behavior in last 4 weeks.

- Proportion of participants with a CGI-I (Clinical Global Impression-Improvement) score of 2 or better at Week 4 [ Time Frame: Baseline to Week 4 ]CGI-I specific to hyperactivity, inattention and impulsivity behaviors. The CGI-I is a seven-point scale that requires the clinician to assess how much the patient's illness has improved or worsened relative to a baseline state at the beginning of the intervention. 1 = Very much improved, 2 = Much improved, 3 = Minimally improved, 4 = No change, 5 = Minimally worse, 6 = Much worse, 7 = Very much worse.
