DNLI NASDAQ

Company Description

Denali Therapeutics Inc. (NASDAQ: DNLI) is a biotechnology and biopharmaceutical company focused on developing product candidates engineered to cross the blood-brain barrier (BBB) for the treatment of neurodegenerative diseases, lysosomal storage diseases and other serious conditions. According to company disclosures, Denali is based in South San Francisco, California and trades on the Nasdaq under the symbol DNLI. The company describes itself as pioneering a new class of biotherapeutics designed to reach the brain using its proprietary TransportVehicle™ (TV) platform.

Core focus and therapeutic areas

Denali’s stated goal is to deliver effective medicines for people living with neurodegenerative diseases, lysosomal storage diseases and other serious diseases. Its work includes programs in Hunter syndrome (mucopolysaccharidosis type II, or MPS II), Sanfilippo syndrome type A (MPS IIIA), granulin-related frontotemporal dementia (FTD-GRN), Parkinson’s disease, Alzheimer’s disease, Pompe disease, Gaucher disease and MPS I, among others. The company reports that it rigorously assesses genetically validated targets, engineers delivery across the BBB and uses biomarkers to demonstrate target and pathway engagement.

TransportVehicle™ platform and blood-brain barrier delivery

A central element of Denali’s business is its TransportVehicle™ (TV) platform, which it describes as a proprietary technology designed to deliver large therapeutic molecules throughout the body, including the brain, by crossing the BBB after intravenous administration. The platform is based on engineered Fc domains that bind to natural transport receptors such as the transferrin receptor and CD98 heavy chain amino acid transporter, which are expressed at the BBB. Through receptor-mediated transcytosis, these engineered molecules can transport therapeutic cargo into the brain.

Denali reports that antibodies and enzymes engineered with the TV platform have shown more than 10- to 30-fold greater brain exposure in animal models compared with similar molecules without this technology, and that TV-enabled oligonucleotides have demonstrated more than a 1,000-fold greater brain exposure in primates than systemically delivered oligonucleotides without the platform. The company states that the TV platform has been clinically validated and that multiple TV-enabled programs are in clinical development.

Lead program: tividenofusp alfa (DNL310, ETV:IDS) for Hunter syndrome

Denali identifies tividenofusp alfa (DNL310) as its lead investigational enzyme replacement therapy for Hunter syndrome (MPS II). Tividenofusp alfa is composed of the iduronate 2‑sulfatase (IDS) enzyme fused to the TV platform and is designed to deliver IDS into both the brain and the body, with the goal of addressing behavioral, cognitive and physical symptoms of MPS II. The U.S. Food and Drug Administration (FDA) has granted Fast Track, Breakthrough Therapy, Orphan Drug and Rare Pediatric Disease designations to tividenofusp alfa, and the European Medicines Agency has granted Priority Medicines designation, according to company press releases.

Denali reports results from an open-label Phase 1/2 study of tividenofusp alfa in children with MPS II, including reductions and normalization in key disease biomarkers, normalization of liver volume, improvement in hearing thresholds and skill gains on measures of adaptive behavior and cognition. The company states that the most common treatment-related adverse events were infusion-related reactions that decreased with continued use. A Biologics License Application (BLA) for tividenofusp alfa for MPS II is under FDA Priority Review, with a Prescription Drug User Fee Act (PDUFA) target action date of April 5, 2026, as disclosed in multiple news releases and related SEC filings. Denali is conducting the global Phase 2/3 COMPASS study in participants with MPS II in North America, South America and Europe to generate confirmatory evidence and support global regulatory submissions.

Additional TV-enabled lysosomal storage disease programs

Beyond Hunter syndrome, Denali highlights several TV-enabled programs targeting other lysosomal storage disorders:

DNL126 (ETV:SGSH) for Sanfilippo syndrome type A (MPS IIIA): An enzyme TransportVehicle (ETV) program for MPS IIIA. Denali reports that an ongoing Phase 1/2 study has completed enrollment and that cerebrospinal fluid heparan sulfate has been aligned with the FDA as a reasonably likely surrogate endpoint to support an accelerated approval path. Planning for a global Phase 3 confirmatory study is described as ongoing.
DNL952 (ETV:GAA) for Pompe disease: An ETV-enabled program designed to enhance delivery of the missing GAA enzyme into muscle tissues and across the BBB into the brain. Denali discloses that the FDA has lifted a clinical hold on the Investigational New Drug (IND) application for DNL952 and that the company plans to proceed with a Phase 1 study.
DNL111 (ETV:GCase) for Parkinson’s disease and Gaucher disease, DNL622 (ETV:IDUA) for MPS I: These are described as ETV programs in IND‑enabling stages, aimed at additional lysosomal storage and related disorders.

Neurodegenerative disease and oligonucleotide programs

Denali also reports a portfolio of programs in neurodegenerative diseases that use small molecules and TV-enabled oligonucleotides and antibodies:

BIIB122/DNL151 (small molecule LRRK2 inhibitor) for Parkinson’s disease: A small molecule program co-developed with Biogen. The company states that the global Phase 2b LUMA study in early-stage Parkinson’s disease has completed enrollment, with a clinical readout expected in 2026, and that Denali’s Phase 2a BEACON study in LRRK2-associated Parkinson’s disease remains ongoing.
TAK‑594/DNL593 (PTV:PGRN) for GRN-related frontotemporal dementia (FTD‑GRN): A program developed in collaboration with Takeda, designed to deliver progranulin across the BBB for FTD‑GRN. Denali reports that a Phase 1/2 study is ongoing.
DNL628 (OTV:MAPT) for Alzheimer’s disease: An Oligonucleotide TransportVehicle™ (OTV) program designed to reduce tau protein by targeting the MAPT gene. Denali discloses that a Clinical Trial Application for a Phase 1b study has been approved and that study start-up activities are underway.
DNL921 (ATV:Abeta) for Alzheimer’s disease: An Antibody TransportVehicle (ATV) program in IND-enabling stage. Denali has reported preclinical data showing that TV-enabled anti‑amyloid beta antibodies improved brain distribution and affected amyloid-related imaging abnormalities in animal models.
DNL422 (OTV:SNCA) for Parkinson’s disease: An OTV program in IND‑enabling stage targeting the SNCA gene.
