- New trontinemab knowledge proceed to assist speedy and deep, dose-dependent discount of amyloid plaques in Section Ib/IIa Brainshuttle™ AD examine
- Information on the Elecsys® pTau181 plasma take a look at reveal potential to precisely rule out amyloid pathology, one of many hallmarks of Alzheimer’s illness
- Roche will provoke a Section III programme for trontinemab later this 12 months based mostly on totality of information
Basel, 3 April 2025 – Roche (SIX: RO, ROG; OTCQX: RHHBY) introduced at present that new knowledge had been introduced at the AD/PD 2025 Worldwide Convention on Alzheimer’s and Parkinson’s Ailments in Vienna, Austria. Highlights included shows from the continuing trontinemab Section Ib/IIa Brainshuttle™ AD examine demonstrating dose-dependent speedy amyloid depletion from the mind and the potential of the Elecsys® pTau181 plasma take a look at to rule out amyloid pathology. Roche additionally introduced the initiation of a Section III programme for trontinemab, which is anticipated later this 12 months.
“We’re happy with the progress throughout our Alzheimer’s portfolio as we transfer forward with a Section III trontinemab programme and proceed to increase our diagnostic options,” stated Levi Garraway, M.D., Ph.D., Roche’s Chief Medical Officer and Head of International Product Improvement. “Effectively over 55 million folks worldwide live with dementia, of which round 70% have Alzheimer’s. Furthermore, as much as three-quarters of individuals experiencing signs of Alzheimer’s stay undiagnosed. This rising inhabitants wants extra correct, much less invasive diagnostic approaches paired with efficient disease-modifying therapies to gradual neurodegeneration as early as doable.”
Trontinemab
Preliminary outcomes for trontinemab from 114 contributors in the 1.8 or 3.6 mg/kg double-blind interval recommend speedy and deep, dose-dependent discount of amyloid plaques in the mind as measured by amyloid positron emission tomography (PET). Trontinemab diminished amyloid ranges under the 24 centiloid threshold in 81% of contributors (n=21/26) in the three.6 mg/kg dose group after 28 weeks. Primarily based on knowledge in the sphere, each the pace of amyloid reducing, and the power to decrease under the amyloid positivity threshold early on, are necessary to realize clinically significant profit in early Alzheimer’s illness. These knowledge had been strengthened by early and important reductions in fluid biomarkers of Alzheimer’s illness together with whole tau, phosphorylated Tau (pTau)181, pTau217 and neurogranin measured in cerebrospinal fluid (CSF) and plasma.
Trontinemab continues to indicate a beneficial security and tolerability profile. Amyloid-related imaging abnormalities-edema/effusion (ARIA-E) had been noticed in <5% (n=3/114) of contributors (blinded knowledge), which had been radiographically gentle, and there was one case related to gentle signs.
Trontinemab is at the moment being studied in the Section Ib/IIa Brainshuttle AD examine assessing the protection, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of trontinemab in contributors with Alzheimer’s illness.
Diagnostics
Outcomes from 604 contributors in a multicentre examine of Roche’s Elecsys pTau181 plasma take a look at had been introduced, demonstrating its potential to precisely rule out amyloid pathology, a trademark of Alzheimer’s illness, in folks with cognitive impairment.
The Elecsys pTau181 take a look at is a minimally invasive blood take a look at that measures pTau181 protein in plasma. By ruling out these with out indicators of amyloid pathology, the take a look at can assist to keep away from pointless testing utilizing CSF or PET, that are extra invasive and usually include lengthy ready occasions and excessive prices. This may consequence in additional delays to analysis and value to healthcare techniques. Roche anticipates checks being out there in Europe by late 2025, with the U.S. following after.
Different actions at the AD/PD 2025 Worldwide Convention
Parkinson’s illness
Outcomes from the Section IIb PADOVA examine had been introduced for the primary time, investigating prasinezumab in 586 folks with early-stage Parkinson’s illness whereas on secure symptomatic remedy. Though the examine missed its main endpoint, the totality of information recommend doable profit in early-stage Parkinson’s illness. Prasinezumab confirmed potential medical efficacy in the first endpoint of time to confirmed motor development with a hazard ratio (HR)=0.84 [0.69-1.01] and p=0.0657, lacking statistical significance. In a pre-specified evaluation, the impact of prasinezumab was extra pronounced in the inhabitants handled with levodopa (75% of contributors), HR=0.79 [0.63-0.99]. Constant optimistic developments throughout a number of secondary and exploratory medical endpoints had been additionally noticed, in addition to a possible organic impact of prasinezumab on MRI biomarkers. Prasinezumab continues to be nicely tolerated and no new security alerts had been noticed in the examine. Given the excessive degree of unmet want for these sufferers, Roche is additional evaluating examine knowledge to find out subsequent steps.
About Roche in Neurology
Neurology is a serious focus of analysis and growth at Roche. Our purpose is to pursue groundbreaking science to develop new diagnostic options and therapies that assist enhance the lives of individuals with continual and doubtlessly devastating ailments. Roche is dedicated to utilizing its diagnostic and pharmaceutical capabilities in an effort to raised detect and deal with neurological ailments as early as doable, and working towards stopping them altogether.
Roche is investigating greater than a dozen medicines for neurological issues, together with Alzheimer’s illness, a number of sclerosis, spinal muscular atrophy, Duchenne muscular dystrophy, Parkinson’s illness, neuromyelitis optica spectrum dysfunction and Huntington’s illness. Roche diagnostics provides one of many broadest portfolio of options, together with accredited and investigational instruments, reminiscent of digital and blood-based checks and CSF assays, aiming to extra successfully detect, diagnose and monitor the illness.

About trontinemab
Trontinemab is an investigational Brainshuttle™ bispecific 2+1 amyloid-beta antibody particularly engineered for enhanced entry to the mind to allow speedy discount of amyloid in folks with Alzheimer’s illness. Trontinemab is designed for the environment friendly transport throughout the blood-brain barrier to focus on aggregated types of amyloid beta and take away amyloid plaques in the mind.
The distinctiveness of trontinemab is predicated on Roche’s proprietary Brainshuttle expertise combining an amyloid beta-binding monoclonal antibody with a transferring receptor (TfR1) shuttle module. In consequence, excessive central nervous system (CNS) publicity of trontinemab could also be achieved at low doses, resulting in a speedy and deep amyloid clearance. Resulting from its distinctive properties, trontinemab would possibly unlock the total potential of disease-modifying monoclonal antibodies by successfully penetrating the mind and doubtlessly resulting in slowing of illness development.
About prasinezumab
Prasinezumab is an investigational monoclonal antibody designed to selectively bind aggregated alpha-synuclein (α-syn) and scale back neuronal toxicity. By concentrating on the build-up of α-syn protein in the mind, prasinezumab can doubtlessly forestall additional accumulation and spreading between cells, thereby slowing down the development of the illness. The proof supporting concentrating on α-syn aggregates as a mechanism of motion in Parkinson’s illness is predicated on a variety of scientific proof in the sphere.
Prasinezumab is at the moment being assessed in ongoing open-label extensions of the Section II PASADENA and Section IIb PADOVA research. The security database for prasinezumab consists of information from greater than 900 Parkinson’s illness examine contributors which have been handled with the investigational drugs, together with greater than 500 who had been handled over 1.5-5 years.
Roche entered right into a Licensing, Improvement, and Commercialisation settlement with Prothena in December 2013 to develop and commercialise monoclonal antibodies concentrating on α-syn, reminiscent of prasinezumab, for the remedy of Parkinson’s illness.
