Brief Summary:
The purpose of this study is to determine efficacy of guanfacine immediate release (GIR) for the treatment of hyperactivity/impulsivity and inattention in children 6-12 years of age with Down syndrome (DS) after 8 weeks of treatment.

Condition or disease Intervention/treatment Phase
Hyperactivity in Children With Down Syndrome Impulsivity in Children With Down Syndrome Drug: Guanfacine Hydrochloride Immediate Release Drug: Placebo Phase 2

Detailed Description:
This is a randomized, double-blind, placebo-controlled flexibly dosed trial of guanfacine immediate release (GIR) in children with Down syndrome (DS) and symptoms of hyperactivity, inattention, and impulsivity. Participants will undergo a screening period of up to 29 days. Eligible participants meeting study criteria will be randomized 2:1 GIR or placebo. There are a total of up to 4 in person visits (screening, baseline, at Week 4, and at Week 8). Participants will receive GIR or placebo for up to 8 weeks. Weekly dose escalation will be determined via a telephone assessment at Weeks 1-3 and Weeks 4-7. Unmasking of participant and site staff will occur at the week 8, in-person visit. After unmasking, participants who were randomized to receive GIR will be given the option to 1) remain on GIR and to transition to open-label GIR per standard of care or 2) taper off of GIR. A Telephone Safety Assessment will be conducted for all participants, at 5 (+2) days after final study product administration. Blood specimens will be collected at the Week 4 and Week 8 visits for Pharmacokinetic (PK) analyses and lab assessments. Participants will be asked to keep a daily study diary and will complete study measures at screening/baseline, Week 4 and Week 8. Parents/Caregivers will need to complete the Study Diary during the bridge/taper period for those who are in the GIR arm.

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.

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. Change in parent-rated ABC-H (Aberrant Behavior Checklist-Hyperactivity) subscale core [ Time Frame: Baseline to Week 4 ]
    Change from baseline to Week 4 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.

  2. 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.

  3. Proportion of participants with a CGI-I (Clinical Global Impression-Improvement) score of 2 or better at Week 8 [ Time Frame: Baseline to Week 8 ]
    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.

  4. Safety of GIR (guanfacine immediate release) [ Time Frame: Baseline through Week 8 ]
    Number of participants with adverse events (AEs), serious adverse events (SAEs), or events of special interest (ESIs).
