Study Endpoints

Primary Endpoints

Change From Baseline in Attention Deficit Hyperactivity Disorder Rating Scale, Version 5 (ADHD-RS-5) Total Score
Baseline to Visit 8 (Week 6)

The ADHD-RS-5 is comprised of 18 frequency items and 12 impairment items. Each frequency item was scored on a scale from 0 = "Never or rarely" to 3 = "Very often". The ADHD-RS-5 total score was calculated as the sum of the 18 frequency item scores. The total score ranges from 0 to 54. Higher scores indicate greater symptom severity. Change from baseline value were calculated as the assessment value minus the baseline value.

Clinical Global Impression - Global Improvement (CGI -I) Response
Visit 3 to Visit 8 (Week 6)

The CGI-I item is rated on a 7-point scale from 1 = "Very much improved", 2 = "Much improved", 3 = "Minimally improved", 4 = "No change", 5 = "Minimally worse", 6 = "Much worse", 7 = "Very much worse". Response is defined as achieving a CGI-I score of 1 or 2, scores of 3 to 7 or missing are defined as Non Response

Frequently asked questions about AEVI-001

What is AEVI-001?

AEVI-001 is an investigational small molecule being developed by Avalo Therapeutics, Inc. for Attention Deficit Hyperactivity Disorder. It has been studied in Phase 2 clinical trials in children and adolescents. It is not an approved therapy and remains in clinical development.

What is AEVI-001 used for in ADHD?

AEVI-001 is being studied for the treatment of Attention Deficit Hyperactivity Disorder in children and adolescents. Two completed Phase 2 trials evaluated its efficacy and safety in this population, one in patients with mGluR mutations and one in patients without those mutations.

Who is developing AEVI-001?

AEVI-001 is being developed by Avalo Therapeutics, Inc., which trades under the ticker AVTX. The company has sponsored the clinical program evaluating the drug in Attention Deficit Hyperactivity Disorder.

What phase is AEVI-001 in?

AEVI-001 is in Phase 2 development. Both of its clinical trials in Attention Deficit Hyperactivity Disorder have been completed, and no trials are currently active. The drug is investigational and has not been approved for any indication.

What clinical trials is AEVI-001 in?

AEVI-001 has been evaluated in two completed Phase 2 trials. NCT03609619 studied children and adolescents with ADHD without mGluR mutations and enrolled 109 participants. NCT03265119 studied children and adolescents with ADHD and mGluR mutations and enrolled 69 participants. Both were randomized, double-blind, and placebo-controlled.

How was AEVI-001 studied in its clinical trials?

Both Phase 2 trials of AEVI-001 were randomized, double-blind, and placebo-controlled. They enrolled a combined 178 participants aged 6 years and older in the United States. NCT03609619 enrolled 109 patients without mGluR mutations, and NCT03265119 enrolled 69 patients with mGluR mutations.
