There is an increasing interest in using magnetic resonance imaging (MRI) as a tool for precision medicine in autism spectrum disorder (ASD). This study investigated the feasibility of MRI scanning in a large comprehensive, inclusive and test heavy clinical trial for children (aged 3-12 years) with ASD, without functioning constraints for participation. Of the 71 participants enrolled who consented to the MRI, 24 participants (38%) successfully completed an MRI scan at baseline along with other assessments. This scanning followed a familiarization procedure at two preceding visits. At post-treatment, 21 participants successfully completed the MRI scan. This study highlights the challenge of completing MRI assessments in ASD populations when conducted as one of a number of tests in a clinical trial.

Background: The presence of multiple comorbid pathologic features in late-onset dementia has been well documented across cohort studies that incorporate autopsy evaluation. It is likely that such mixed pathology potentially confounds the results of interventional trials that are designed to target a solitary pathophysiologic mechanism in Alzheimer's disease and related dementias (ADRD).
Method: The UK ADRC autopsy database was screened for participants who had previously engaged in therapeutic interventional trials for Alzheimer's disease, vascular cognitive impairment, dementia, and/or ADRD prevention trials from 2005 to the present.

The lack of an in-vivo pathology marker for synuclein pathology has been a long standing challenge for dementia for Lewy bodies (DLB) research. This issue is critically important for phase II trials, which are often small, requiring the precise measurement of the biological effects, whether disease modifying or symptomatic. Recent advances have enabled the determination of alpha-synuclein pathology status with CSF measurements, using aggregation assays [RT-QUIC].

Background: Glucagon-like peptide 1 (GLP-1) is a peptide hormone that plays several physiological roles in treating diabetes and in protecting the brain. Recent clinical trials testing 4 different GLP-1 class drugs in phase 2 trials showed a clear correlation between neuroprotection and the ability to cross the BBB. Exenatide and Lixisenatide both showed excellent protective effects in patients Parkinson's disease (PD) and both drugs can readily cross the BBB.

Recent clinical trial outcomes for monoclonal antibodies lecanemab and donanemab, establish the relevance of targeting pathological Abeta for clearing amyloid plaques in Alzheimer's disease. ACI-24.

Low-recruiting sites represent a large financial and operational burden and may negatively impact trial success either by selecting inappropriate participants and/or high prevalence of data quality issues. We previously reported that >60% of sites in schizophrenia clinical trials recruited ≤5 participants.
