Presents results on ABvac40 and ABtest-MS studies at the AD/PD™ 2022 Conference in Barcelona News provided by Share this article ABvac40: Meets the primary objectives on safety and efficacy of the first part of the phase II clinical study. Also confirms the vaccine's excellent safety and tolerability profile, as well as a strong immune response in patients with amnestic mild cognitive impairment (aMCI) or very mild Alzheimer's disease (vm-AD) ABvac40 is based on an active immunization against the amyloid-beta 40 protein to fight early-stage AD ABtest-MS: Two studies confirm the test's ability to identify precisely those subjects with cerebral amyloid load, one of the first signs of early-onset AD ABtest-MS, developed entirely in Araclon based on mass spectrometry, is capable of quantifying amyloid-beta 40 and 42 proteins – both associated with the risk of having AD – in plasma samples ZARAGOZA, Spain, March 15, 2022 /PRNewswire/ -- Araclon Biotech, a Grifols Group company dedicated to the research and development of therapies and diagnostic methods applied to degenerative diseases, will present topline results for the first part of its phase II clinical trial on its active immunotherapy, ABvac40, against Alzheimer's Disease (AD), as well as data on two studies of its assay, ABtest-MS, to identify early-stage AD. Araclon will present its findings at the 16th International Conference on Alzheimer's and Parkinson's Diseases and related neurological disorders (AD/PD™ 2022), held March 15-20 in Barcelona. Regarding the vaccine ABvac40, the principal data analyzed until now (Part A) are satisfactory in that they support the continuation of the trial's extension phase (Part B). Researchers have confirmed that the vaccine shows an excellent safety and tolerability profile, in addition to demonstrating a high immune response in patients with amnestic mild cognitive impairment (aMCI) or very mild AD. "We are pleased to communicate these data at the international Conference AD/PD™ 2022, which confirm previous results on the safety and tolerability of ABvac40 in the early stages of Alzheimer's disease," said Jose Terencio, Araclon CEO and Vice President of Innovation at Grifols. "In addition the vaccine demonstrates that it induces a strong immune response characterized by the increase in anti-Aβ40 titers at the same time that Aβ40 levels rise in plasma. We are analyzing the results of the secondary variables (exploratory), related to efficacy, and we hope that ABvac40 shows its potential and lead to an innovative vaccine for patients." This multicenter, random and double-blind phase II trial included a total of 124 patients with aMCI or very mild AD and were divided evenly between the treated group and the control group. As far as the primary objective of safety, there were no significant differences between the participants in the group that received ABvac40 and those dosed with the placebo, including incidences of ARIA-H. No ARIA-E events were reported during Part A of the study. These data confirm those obtained in phase I and presented in July 2016, which showed a good safety profile. With respect to the other primary objective, efficacy (immunogenicity), the administration of six doses of ABvac40 resulted in a significant increase in the specific antibody levels, greater than those observed in the phase I trial (three doses). This phase II evaluates as secondary efficacy variables (exploratory) changes in the disease's biomarkers, as well as in cognition and the quality of life resulting from ABvac40. The study's Part B is progressing according to plan. Studies confirm the predictive potential of ABtest-MS for the early diagnosis of AD in heterogeneous cohorts with different clinical characteristics In addition, Araclon Biotech continues with its research focused on the development of solutions to detect AD in its early stages. Diverse studies confirm the high predictive ability of its assay ABtest-MS to identify precisely those subjects with cerebral amyloid load, a sign of early-onset AD, which would enable management of the condition in its initial phases. ABtest-MS, a novel and unique method developed entirely in Araclon and based on the mass spectrometry technique, is capable of accurately quantifying amyloid 40 and 42 proteins – both associated with the risk of having AD – in plasma samples. The results to be presented at the AD/PD™ 2022 Conference are centered on two recent studies. Data from the trial conducted on the FACEHBI cohort, obtained after two years of follow up, confirm the potential of the ABtest-MS to predict the cerebral amyloid load, an initial sign of AD, in individuals with subjective memory complaints (SMCs) and the potential that the analysis of these markers have as an indicator of how the condition evolves. The data corresponding to five years of follow up with the cohort are currently being analyzed. In the second study, the multicenter A4 Study carried out in 50 centers, the ABtest-MS predicted the cerebral deposit of the amyloid protein (measured by PET) in plasma samples from 731 subjects. It also confirmed the suitability of utilizing a centralized and extensively validated method such as this assay in these broad and heterogenous studies. These data confirm other results previously obtained on more than 1,000 subjects in different AD stages from various international cohorts (BioFINDER, DPUK) that have been recently featured in scientific publications such as Alzheimer's Research & Therapy, Nature Aging and Alzheimer's & Dementia: The journal of the Alzheimer's Association, confirming the relation between amyloid biomarkers in plasma and AD. "This test's predictive ability makes it ideal to detect early-stage Alzheimer's and accelerate the recruitment for clinical trials of new treatments, reducing the screening failure rate and associated costs," said Terencio. ABtest-MS is a differentiating method that doesn't contain antibodies and whose process avoids enzymatic digestion, saving time and expense.
