Aβ amyloid β, SAD single ascending dose. mAb158 is a murine monoclonal antibody that was raised to target protofibrils [3], and BAN2401 is the humanized IgG1 monoclonal version that selectively binds to Aβ protofibrils. Considering that no titration period is included in the CLARITY AD trial, the onset of clinical efficacy may occur earlier with BAN2401 than aducanumab. The minimum observed concentration at steady-state (Css, min) achieved with this dosing regimen was approximately 40 μg/mL, with an accumulation factor of approximately 1.4. Thus, it was not possible to assess target engagement of BAN2401 in CSF.

Google Scholar. In addition, single samples were collected three weeks and three months post dose. In addition, PK results from completed earlier cohorts were used to amend the MAD dose frequency to reflect the shorter than expected half-life and to investigate if the PK profile in CSF might be comparable to that in serum. One subject had a CSF concentration of 624 ng/mL (CSF: serum ratio 0.81 %) and the other a CSF concentration of 72 ng/mL (CSF:serum ratio 0.07 %).

Ahmed M, Davis J, Aucoin D, Sato T, Ahuja S, et al. The mean Cmax and the AUC increased approximately proportionally with BAN2401 dose from 0.3-15 mg/kg. Six subjects in the MAD cohorts, of which one was on placebo, had ARIA-Hs detected by MRI at baseline. Treatment periods of the SAD and MAD cohorts took place in a staggered parallel manner. The PK profile has guided us for selecting dose and dose regimens in the ongoing phase 2b study. Neurodegener Dis. The 10 mg/kg biweekly dose achieved minimum steady state levels of approximately 40 μg/mL after three doses, with an accumulation factor of approximately 1.4. BAN2401 was well-tolerated across all doses. 2012;79:229–36.

On the basis of these findings, a Phase 2b efficacy study has been initiated in early AD. Several monoclonal antibodies for the treatment of AD have been in development over the last decade. doi: 10.1517/14712590902828285. The purpose of this study is to evaluate the efficacy of BAN2401 in subjects with J Alzheimers Dis. BAN2401-G000-201, a randomized double-blind clinical trial, utilized a Bayesian design with response-adaptive randomization to assess 3 doses across 2 regimens of lecanemab versus placebo in early Alzheimer’s disease, mild cognitive impairment due to Alzheimer’s disease (AD) and mild AD dementia. Tucker S, Möller C, Tegerstedt K, Lord A, Laudon H, Sjödahl J, Söderberg L, Spens E, Sahlin C, Waara ER, Satlin A, Gellerfors P, Osswald G, Lannfelt L. The murine version of BAN2401 (mAb158) selectively reduces amyloid-β protofibrils in brain and cerebrospinal fluid of tg-ArcSwe mice. In this cohort, the CSF:serum ratio was 0.13 % at 24 h after the final dose, and increased to 0.29 % at 14 days after the final dose. Neurology. BAN2401 is a humanized monoclonal antibody that is the result of a strategic research alliance between BioArctic and Eisai. Walsh DM, Lomakin A, Benedek GB, Condron MM, Teplow DB. One subject on BAN2401 in the 1 mg/kg SAD cohort experienced an asymptomatic ARIA-H, discovered on Day 21 routine MRI scan considered by the investigator to be possibly related to the study drug. 4, Table 6). Miami neurologist, Dr. Jeff Gelblum, is a study investigator who is involved in recruiting patients for this protocol. BAN2401-G000-201. This volume provides in-depth descriptions and discussion of clinical trial designs based on novel data analysis of high-quality trials for 11 different neurological conditions in order to ultimately improve the quality of care in neurology ... 3a and b and findings for other pharmacokinetic parameters are listed in Table 4. Cohorts were initiated after review of the safety and PK data of the previous cohorts. Source: ClinicalTrials.gov ID: NCT01767311. A beneficial safety profile allowing for efficacious dose levels without undesired side effects is pivotal for success. Mastrangelo IA, Ahmed M, Sato T, Liu W, Wang C, Hough P, Smith SO. PMC The presence of amyloid related imaging abnormalities (ARIA, E for edema, H for hemorrhage) was assessed with magnetic resonance imaging (MRI). Found insideThis is a book about living with Alzheimer’s, not dying with it. Evidence for a dose relationship with plasma biomarkers was evaluated. This is a one-year, double-blind placebo-controlled randomized clinical trial that compares montelukast to placebo in individuals with mild cognitive impairment (MCI) and early Alzheimer's disease (AD) dementia. Due to sampling error only two subjects in the 15 mg/kg SAD group had CSF concentrations measured on Day 10. The subject remained asymptomatic throughout the study, and the ARIA-H had completely resolved by Day 180. Biweekly infusions of BAN2401 (10 mg/kg) achieved steady state serum concentrations after the third dose, i.e., after approximately six weeks of treatment. Prevention and treatment information (HHS).

Correspondence to Perspectives on future Alzheimer therapies: amyloid-β protofibrils - a new target for immunotherapy with BAN2401 in Alzheimer's disease. Data from recent AD trials remain inconclusive, but provide some suggestion that a treatment effect of immunotherapy is possible. BAN2401 Phase III Clinical Trial. volume 8, Article number: 14 (2016) Google Scholar. What Is This Study About? Amyloid is a protein that builds up in people who can go on to have memory problems and develop Alzheimer’s disease. The most frequently observed TEAEs in subjects treated with multiple doses of BAN2401 were upper respiratory tract infection (16.7 vs. 12.5 % on placebo), headache (12.5 vs. 25 % on placebo), and orthostatic hypotension (12.5 vs. 0 % on placebo) (Tables 2 and 3). Single BAN2401 doses from 0.3-15 mg/kg showed first order elimination kinetics. -, Englund H, Sehlin D, Johansson AS, Nilsson LN, Gellerfors P, Paulie S, Lannfelt L, Pettersson FE. The Phase 3 study — to be conducted in the U.S., Canada, Japan, Australia, Singapore, and Europe — will test the therapy in people who are in the early stage of the neurological disorder and do not yet show symptoms. Study design with overlapping SAD-MAD cohorts, where treatment periods took place in a staggered parallel manner. Bapineuzumab, a monoclonal antibody targeting non-selectively all forms of Aβ, generated side-effects leading to lowering of treatment doses and no treatment effect was found [12]. Neuron. If more gantenerumab gets into the brain, perhaps we could see more effect.
