Pfizer Announces Topline Results Of First Of Four Studies In Bapineuzumab Phase iii Program
Co-Primary Clinical Endpoints Not Met inwards Study of Patients with Alzheimer’s Disease Who Carry The ApoE4 Genotype
Pfizer Inc. (NYSE: PFE) announced today that the co-primary clinical endpoints, alter inwards cognitive together with functional functioning compared to placebo, were non met inwards the Janssen Alzheimer Immunotherapy R&D LLC (Janssen AI)-led Phase iii lawsuit of intravenous (IV) bapineuzumab inwards patients with mild-to-moderate Alzheimer’s illness who ship the ApoE4 (apolipoprotein E epsilon 4) genotype (Study 302). Pfizer together with Janssen AI are partners inwards the Alzheimer’s Immunotherapy Program (AIP).
These clinical findings possess got been shared with regulatory regime together with study investigators then that participants inwards the ongoing clinical programme tin move informed. Because inwards this study clinical efficacy was non demonstrated inwards ApoE4 carriers, the Janssen AI together with Pfizer Joint Steering Committee for the AIP has decided that participants from this study who enrolled inwards a follow-on extension study volition no longer have doses of bapineuzumab. However, these patients volition possess got a follow-up evaluation.
Based on a comprehensive review of the information past times the independent security monitoring committee, all other ongoing Janssen AI together with Pfizer bapineuzumab studies are continuing equally planned together with without modifications.
Study 302 is the starting fourth dimension of iv placebo-controlled Phase iii studies to consummate inwards the comprehensive evolution programme of bapineuzumab IV. Janssen AI is leading 2 Phase iii studies of patients who are ApoE4 carriers (Study 302) together with non-carriers (Study 301) at sites primarily inwards North America. Pfizer is conducting 2 Phase iii studies of patients who are ApoE4 carriers (Study 3001) together with non-carriers (Study 3000) at sites primarily exterior of North America.
The Alliance volition expedite the completion of an interim analysis for the on-going, Pfizer-conducted Phase iii study of ApoE4 carriers (Study 3001) based on the results of Study 302.
The topline results from Study 301 inwards patients with mild-to-moderate Alzheimer’s illness who produce non ship the ApoE4 genotype are expected to move announced afterwards this summer.
“While nosotros are disappointed inwards the topline results of Study 302, a to a greater extent than consummate agreement of bapineuzumab together with its potential utility inwards mild-to-moderate Alzheimer’s illness volition move gained next the availability of additional data, including information from the soon-to-be available non-carrier Study 301,” said Steven J. Romano, M.D., senior vice president, head, Medicines Development Group, Global Primary Care Business Unit, Pfizer Inc. “We recognize that Alzheimer’s illness is really complex, but Pfizer, along with our partner Janssen AI, remains committed to advancing the scientific discipline of Alzheimer’s disease, with the ultimate finish of delivering innovative together with meaningful novel handling options to patients.”Data from both the ApoE4 carrier (Study 302) together with non-carrier (Study 301) studies possess got been accepted equally a late-breaker together with volition move presented inwards September at the European Federation of Neurological Societies coming together inwards Stockholm.
The presence of the ApoE epsilon 4 genotype is a genetic run a jeopardy element for Alzheimer’s illness together with is associated with increased beta-amyloid plaques inwards the brains of patients with the disease. Topline results of Study 302 request that alongside patients treated with bapineuzumab IV the most usually observed serious adverse events which occurred to a greater extent than usually than placebo together with with an incidence of at to the lowest degree 1 per centum were ARIA-E together with dehydration. ARIA-E (amyloid-related imaging abnormalities-edema or effusion) refers to changes inwards the encephalon that may move due to fluid (water together with protein) leaking from blood vessels, which tin move detected using magnetic resonance imaging (MRI) of the brain.
About the Bapineuzumab IV Phase iii Studies
There are iv placebo-controlled Phase iii studies inwards the bapineuzumab clinical evolution program. Janssen AI is leading 2 18-month, Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group, efficacy together with security studies of patients who are ApoE4 carriers (Study 302) together with Apoe4 non-carriers (Study 301). The 2 co-primary clinical endpoints are alter inwards the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog), a validated mensurate of cognition, together with the Disability Assessment for Dementia (DAD), a validated musical instrument to mensurate function. Study 302 included some 1,100 patients who ship the ApoE4 genotype together with Study 301 includes some 1,300 patients who produce non ship the ApoE4 genotype.
In improver to the Janssen AI-led studies, Pfizer is conducting 2 primarily ex-North America 18-month, Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-group, efficacy together with security studies of patients with mild-to-moderate Alzheimer’s illness who are ApoE4 non-carriers (Study 3000) together with carriers (Study 3001).
About Bapineuzumab IV
Bapineuzumab IV, an investigational therapy existence studied for the handling of mild-to-moderate Alzheimer’s disease, is an antibody that targets beta-amyloid (Aβ), a poly peptide that tin exert toxic effects inwards the encephalon together with is believed to play a primal role inwards the pathology of Alzheimer’s disease.
