NEW: AC Immune initiates new ACI-24 Phase Ib clinical trial in adults ages 35-45 years old with Down syndrome
Status: Ongoing — currently recruiting
AC Immune, through a private-public partnership with NIH and LuMind RDS, has initiated a new Phase Ib clinical trial to evaluate the safety, tolerability and efficacy of ACI-24, an anti-amyloid vaccine, in adults, ages 35-45 years old, with Down syndrome. Based in part on groundbreaking preclinical research studies, ACI-24 is being developed to target treatment of the Alzheimer’s disease-like characteristics, including associated cognitive decline and neurodegeneration, which develop in the majority of individuals with Down syndrome over age 40. This new Phase Ib clinical trial is a randomized, double-blind, placebo-controlled clinical study focused on determining safety, tolerability and immunogenicity (ability to induce antibodies against beta-amyloid) of ACI-24 in adults with Down syndrome, ages 35-45. Effects on cognitive function and biomarkers for Alzheimer’s disease will be assessed as secondary outcomes measures.
This new trial, “A Phase Ib Multi-Center, Double-Blind, Randomized, Placebo-Controlled Dose Escalation Study of the Safety, Tolerability and Immunogenicity of ACI-24 in Adults With Down Syndrome” will be conducted and coordinated by researchers at University of California, San Diego School of Medicine and it is anticipated that the study will include multiple additional trial sites across the US.

Roche initiates new multi-national RG1662 Phase II clinical trial in individuals ages 12-30 years old with Down syndrome
Roche, a leader in innovative research-focused healthcare and the world’s largest biotech company, has initiated a new multi-national Phase II clinical trial to evaluate the efficacy and safety of RG1662 in adolescents and adults, ages 12-30 years old, with Down syndrome. Following the successful completion of the previous groundbreaking Phase I clinical trial with this new drug that is being developed to address the cognitive and behavioral deficits in individuals with Down syndrome, this new significantly larger Phase II trial is a randomized, double-blind, placebo-controlled clinical study in which participants will be randomized to receive RG1662 either at low or high dose or placebo orally twice daily for 26 weeks.
This new trial, “A Study of RG1662 in Adults and Adolescents with Down Syndrome (CLEMATIS)”, will be conducted at multiple sites across the US, including La Jolla, CA, Sacramento, CA, Decatur, GA, Chicago, IL, Baltimore, MD, Boston, MA, Durham, NC, Dallas, TX, Salt Lake City, UT, and Madison, WI. In addition, the trial will be conducted at multiple international sites, including UK (4), France (4), Spain (3), Singapore (1), New Zealand (3), Canada (1), Mexico (5) and Argentina (2).
Elan (now Transition Therapeutics) Announces Study of ELND005
Biotechnology company Elan Corporation, plc (now Transition Therapeutics), has announced the initiation of a Phase 2A clinical trial of ELND005 (scyllo-inositol) in young adults, 18-45 years of age, with Down syndrome. ELND005 is a molecule that may hold the potential to improve cognition in Ds by reducing aggregation of beta-amyloid, which is a product of the amyloid precursor protein (APP) encoded by a gene on chromosome 21 — thus preventing the intraneuronal buildup of beta-amyloid plaques that most people with Ds develop by their 40s — and addressing a metabolic abnormality in Ds that correlates with the severity of cognitive dysfunction. The study now underway will primarily evaluate the safety and pharmokinetics of the molecule, and will include select cognitive and behavioral measures.
There are currently three clinical trial sites in the US: University of California, San Diego in La Jolla, CA; University of California, Irvine in Orange, CA; and Massachusetts General Hospital in Boston, MA. Learn more about this clinical study, including details on participation.
In 2011, Roche initiated an early-stage clinical trial, to test an investigational drug in individuals with Down syndrome. The goal is to evaluate its tolerability and obtain an early reading of its effect on the cognitive and behavioral deficits associated with this condition.
The first stage of this clinical trial involved individuals with Trisomy 21 between the ages of 18-30 residing near one of the eight trial locations around the country. Designed to take place over approximately 16 weeks, the study sought to test the tolerability of the investigational drug. During the study, the heart rate, EEG, and laboratory parameters of safety of the participants were monitored very closely, and parents were involved with tracking physical and any emotional/cognitive changes.

Roche’s Clinical Study to Evaluate Neurocognition Measures
Following its 2011 initiation of the study of RG1662, Roche launched a second new Down syndrome clinical study, “A Non-Drug Study of The Suitability of Neurocognitive Tests and Functioning Scales for the Measurement of Cognitive and Functioning Changes in Individuals with Down Syndrome.” The goal of this study is to evaluate the suitability of neurocognitive tests and functioning scales for the measurement of cognitive and functioning changes in individuals with Down syndrome.
The primary objectives of this clinical study include assessing the performance and reliability of specific scales and measures of cognitive function, memory, adaptive behavior, activities of daily living and impact on caregivers. This is a non-drug study; participants will not be required to take any study medication. Study participants will be administered various neurocognitive tests and their caregiver will be asked to complete questionnaires. The study, with duration up to 27 weeks for participants involving approximately three visits, was designed to involve 90 individuals, ages 12-30 years, with Down syndrome.
There are currently multiple clinical study sites internationally, including two in the US. The University of Arizona in Tucson, AZ and Duke University in Durham, NC represent the US clinical study sites. Dr. Jamie Edgin, Co-Principal Investigator of the Down Syndrome Research Group and LuMind-supported researcher, is the study lead at the University of Arizona.
Roche’s Clinical Trial on Molecular and Functional Imaging
In August 2012, Roche initiated a third Down syndrome clinical trial, “A Molecular and Functional Brain Imaging Study in Individuals with Down Syndrome and Healthy Controls Following Single Dose RG1662”. The goal of this new study was to use MRI and PET imaging scans to evaluate the GABA-A alpha5 receptor expression, occupancy and functional connectivity in the brains of individuals with Down syndrome and healthy controls, ages 18-30 years, following single-dose RG1662. This study was designed to provide additional clinical information to support RG1662 clinical trials in individuals with Down syndrome.
