SOUTH SAN FRANCISCO, Calif., July 09, 2026 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (Nasdaq: DNLI) today announced that co-founder and Chief Executive Officer Ryan Watts, Ph.D., will deliver the opening plenary address, titled “Accelerating the Discovery and Development of Medicines for Neurodegeneration,” at the Alzheimer’s Association International Conference® (AAIC), taking place July 12-15 in London. Dr. Watts will discuss recent scientific advances and future opportunities including new insights in the biology of disease, the use of biomarkers for diagnosis and assessment of treatment effect, and the potential for therapeutics to cross the blood-brain barrier for enhanced delivery to the brain.

“We are entering a new era of drug development for Alzheimer’s disease, driven by significant developments in biology, biomarkers and the blood-brain barrier, which has been a major hurdle for the treatment of neurodegenerative disease,” said Dr. Watts. “At Denali, our work has focused on solving the challenge of brain delivery so that people living with neurologic diseases such as Alzheimer’s can benefit from the power of biotherapeutics. We are excited to be part of the community working to transform the lives of millions of individuals and families worldwide by applying these scientific breakthroughs to deliver the next generation of therapies for Alzheimer’s disease.”

Denali Therapeutics has developed and clinically validated the TransportVehicle™, a proprietary technology designed to effectively deliver biologic therapeutics such as antibodies, enzymes and oligonucleotides across the blood-brain barrier by leveraging the body’s natural iron transport system (the transferrin receptor). In March 2026, Denali received accelerated approval from the U.S. Food and Drug Administration for the first and only FDA-approved biologic specifically designed to cross the blood-brain barrier: AVLAYAH™ (tividenofusp alfa-eknm), an enzyme replacement therapy for the treatment of neurologic manifestations of Hunter syndrome (mucopolysaccharidosis type II) when initiated in presymptomatic or symptomatic pediatric patients weighing at least 5 kg prior to advanced neurologic impairment.

Denali is developing a broad portfolio of investigational, TransportVehicle-enabled therapeutic candidates including DNL628 (OTV:MAPT) and DNL921 (ATV:Abeta) targeting tau and amyloid beta, respectively, the two hallmark pathologies of Alzheimer’s disease.

DNL628 (OTV:MAPT) is enabled by the Oligonucleotide TransportVehicle™ (OTV) and is designed to target the MAPT gene that encodes for tau, which has been shown to be closely associated with cognitive decline. Preclinical research (link) demonstrated that the OTV achieved broad and uniform central nervous system distribution of antisense oligonucleotides, including deeper brain structures, following intravenous administration as compared to intrathecally delivered therapy.1 The first patients in Denali’s Phase 1b clinical study of DNL628 were dosed in the first half of 2026, and Denali expects clinical safety and biomarker proof-of-concept data from the study in 2027.

DNL921 (ATV:Abeta) is enabled by the Antibody TransportVehicle™ (ATV) and is designed to reduce amyloid plaques. In preclinical research published in the journal Science (link), Denali demonstrated improved brain distribution of ATV:Abeta and reduced risk of swelling and small bleeds in the brain – effects collectively known as amyloid-related imaging abnormalities (ARIA) – compared to conventional antibody treatment. The findings suggest that TransportVehicle-enabled brain delivery of immunotherapy bypasses amyloid-laden large vessels by traveling through smaller capillaries, offering a potential strategy to mitigate ARIA risk seen with first-generation anti-amyloid therapies.2 Denali submitted a Clinical Trial Application (CTA) for DNL921 in the first half of 2026 and, pending regulatory approval of the CTA, expects to initiate a Phase 1/1b clinical trial, with potential for clinical safety and biomarker proof-of-concept data in 2027.

About the Denali TransportVehicle Platform

The blood-brain barrier (BBB) is essential in maintaining the brain’s microenvironment and protecting it from harmful substances and pathogens circulating in the bloodstream. Historically, the BBB has posed significant challenges to drug development for central nervous system diseases by preventing most drugs from reaching the brain in therapeutically relevant concentrations. Denali’s TransportVehicle™ (TV) platform is a proprietary technology designed to effectively deliver large therapeutic molecules such as antibodies, enzymes and oligonucleotides throughout the whole body, including the brain, by crossing the BBB after intravenous administration. The TV platform is based on engineered Fc domains that bind to specific natural transport receptors, such as transferrin receptor and CD98 heavy chain amino acid transporter, which are expressed at the BBB and deliver the TV and its therapeutic cargo to the brain through receptor-mediated transcytosis. In animal models, antibodies and enzymes engineered with the TV platform demonstrate more than 10- to 30-fold greater brain exposure than similar antibodies and enzymes without this technology. Oligonucleotides engineered with the TV platform demonstrate more than a 1,000-fold greater brain exposure in primates than systemically delivered oligonucleotides without this technology. Improved exposure and broad distribution in the brain may increase therapeutic efficacy by enabling widespread achievement of therapeutically relevant concentrations of product candidates. The TV platform has been clinically validated, with AVLAYAH™ (tividenofusp alfa-eknm) as the first FDA-approved medicine leveraging transferrin receptor to cross the BBB.
