Clinical Trials on Alzheimer's Disease Conference (CTAD)

The president and chief executive officer of INmune Bio detailed the mechanistic advantages of XPro1595 as a potentially therapeutic benefit for patients with Alzheimer disease and dementia. [WATCH TIME: 5 minutes]

Over a 6-month period, percent change and mean change in brain amyloid levels significantly favored donanemab over aducanumab (Aduhelm; Biogen).

An ongoing phase 1b/2a clinical trial showed that both the ACI-35.030 and JACI-35.054 vaccines are safe as a treatment for patients in the earlier stages of Alzheimer disease, the authors suggested ACI-35.030 suggested as the superior vaccine candidate.

In the pivotal phase 3 Clarity AD trial, lecanemab (Biogen) demonstrated significant impacts on primary and secondary end points, with additional promising results on biomarker analyses and safety.

The GRADUATE studies, which spanned across 32 countries, showed minimal relative reduction in clinical decline for those on gantenerumab relative to placebo over a 116-week treatment cycle.

The neurologist and assistant professor at the University of Toronto discussed the real, but tepid significance of amyloid-related imaging abnormalities seen from lecanemab in early-stage Alzheimer disease. [WATCH TIME: 3 minutes]

The neurologist and assistant professor at the University of Toronto discussed advantages hyperspectral retinal imaging tools like RetiSpec offer and when clinicians can expect to see them in clinical settings.

The neurologist and assistant professor at the University of Toronto provided insight on the clinical use of retinal imaging tools like RetiSpec and the need for further validation of these approaches in Alzheimer disease. [WATCH TIME: 2 minutes]

A phase 3 trial has been initiated to further study masupirdine’s effect on agitation in patients with Alzheimer dementia.

Data show a clinical benefit via a reduction in brain amyloid as early as 3 months in the open-label extension period.

The executive chair at the Rockefeller Neuroscience Institute at West Virginia University shed light on early data from a small sample of patients with early Alzheimer disease who underwent focused ultrasound treatment. [WATCH TIME: 5 minutes]

The executive chair of the Rockefeller Neuroscience Institute at West Virginia University discussed the potential of focused ultrasound for patients with AD, as well as key takeaways for clinicians from a recent study. [WATCH TIME: 5 minutes]

Despite not being significantly superior to placebo on agitation and aggression, lithium showed a greater reduction in those with high Young Mania Rating Scale scores.

Ali Rezai, MD, executive chair at the Rockefeller Neuroscience Institute at West Virginia University, outlined early data from a clinical trial utilizing focused ultrasound to open the blood-brain barrier in patients with mild AD.

The executive chair of the Rockefeller Neuroscience Institute at West Virginia University spoke on how technology can be used to open the blood-brain barrier in patients with AD. [WATCH TIME: 7 minutes]

The magnitude of neflamapimod’s effect on several efficacy measures proved to be consistent with the mechanism of action and prior preclinical data, with p-tau181 data suggesting a stronger effect on nonmixed Lewy body pathology.

Ali Rezai, MD, executive chair of the Rockefeller Neuroscience Institute at West Virginia University, provided an overview of FUS technology and its use in opening the blood-brain barrier.

A higher incidence of gastrointestinal events was observed in the treatment group compared with placebo, similar to what was seen in clinical trials of AMX0035 in amyotrophic lateral sclerosis.

Over 26 weeks of treatment, masupirdine demonstrated a sustained and durable effect on outcomes such as cognition and dementia-related psychosis.

Ivana Rubino, PhD, the head of Medical for Global Alzheimer at Biogen, offered her perspective on the recently presented data at CTAD 2021.

A presentation at CTAD 2021 included data from 5 patients enrolled in a phase 2a trial to evaluate neurocognitive, imaging, and safety outcomes of the therapeutic approach in early AD dementia.

Findings presented at CTAD 2021 included data from surveyed participants with dementia and healthy volunteers about starting in-person or remote research.

The new registry will collect routine clinical practice data from the care of patients with Alzheimer disease who are taking an FDA-approved disease-modifying therapy.

Despite the cohort only consisting of 3 patients with Alzheimer disease, autologous cellular therapy data highlighted the potential of the treatment’s results on cognitive assessments such as Montreal Cognitive Assessment.

The data, which suggest that a lessened decline in cognition and function was correlated with a reduction in plasma p-tau181 levels in those with Alzheimer disease treated with aducanumab (Aduhelm; Biogen), were presented at CTAD 2021.

Study of semorinemab in a larger mITT population confirmed statistically significant reduction in rate of cognitive decline in patients with Alzheimer disease, compared with placebo, but failed to achieve other end points.
