SOUTH SAN FRANCISCO, Calif., Nov. 06, 2024 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (Nasdaq: DNLI) today reported financial results for the third quarter ended September 30, 2024, and provided business highlights.

"As leaders in pioneering a new class of therapeutics that cross the blood-brain barrier, we are making significant progress across our Transport Vehicle (TV)-enabled portfolio," said Ryan Watts, Ph.D., Chief Executive Officer of Denali Therapeutics. "Within our Enzyme TV (ETV) franchise, we are on track to file for accelerated approval of tividenofusp alfa in MPS II in early 2025 after a successful meeting with the FDA in the third quarter. Today, we are also pleased to share that preliminary data from our Phase 1/2 study of DNL126 in MPS IIIA demonstrate a robust reduction from baseline in CSF heparan sulfate levels, including normalization. Based on these data and a positive regulatory environment, we recently expanded the study to support a potential accelerated path. In addition, our recent preclinical publication on our oligonucleotide TV (OTV) technology in Science Translational Medicine, which describes broad and deep brain biodistribution of oligonucleotides following systemic administration of OTV, demonstrates the power and potential of our TV platform to transform the way we treat brain diseases."

Third Quarter 2024 and Recent Program Updates

Late-stage and mid-stage clinical programs

Tividenofusp alfa (DNL310): Enzyme Transport Vehicle (ETV)-enabled, iduronate-2-sulfatase (IDS) replacement therapy in development for MPS II (Hunter syndrome)

• In September, announced the outcome of a successful meeting with the Center for Drug Evaluation and Research (CDER) of the U.S. Food and Drug Administration (FDA) providing a path to filing a biologics license application (BLA) for accelerated approval and subsequent conversion to full approval for tividenofusp alfa (DNL310) for the treatment of MPS II. Agreement was reached that cerebrospinal fluid heparan sulfate (CSF HS) is reasonably likely to predict clinical benefit and can be used as a surrogate endpoint to support accelerated approval for tividenofusp alfa in MPS II. Denali intends to submit the BLA under the accelerated approval pathway in early 2025.
• In September, presented new interim data from the Phase 1/2 study at the Society for the Study of Inborn Errors of Metabolism (SSIEM 2024), including data from additional study participants (N=37) and longer duration of treatment with tividenofusp alfa (up to Week 129) as well as new analyses on biomarkers and clinical outcomes.
• COMPASS, the global Phase 2/3 study, is expected to complete enrollment in 2024.
  

DNL343: eIF2B activator in development for the treatment of amyotrophic lateral sclerosis (ALS)

• DNL343 is being evaluated in Regimen G (DNL343) of the Phase 2/3 HEALEY ALS Platform Trial conducted by the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital (MGH) in collaboration with the Northeast ALS Consortium (NEALS). Enrollment in Regimen G is complete.
  

SAR443820/DNL788: CNS-penetrant RIPK1 inhibitor

• In October, Denali was informed by its strategic partner Sanofi that the K2 Phase 2 study evaluating the safety and efficacy of oditrasertib (SAR443820/DNL788) on serum neurofilament light chain levels in participants with multiple sclerosis was discontinued based on not meeting the primary and key secondary endpoints.
  

BIIB122/DNL151: LRRK2 inhibitor in development for the treatment of Parkinson's disease (PD)

• Biogen is conducting the ongoing global Phase 2b LUMA study of BIIB122 in participants with early-stage Parkinson's disease.
• Denali has initiated screening of participants for the global Phase 2a study to evaluate safety and biomarkers associated with BIIB122 in participants with Parkinson's disease and confirmed pathogenic variants of LRRK2. This study is being funded under the Collaboration and Development Funding Agreement with a third party.

Eclitasertib (SAR443122/DNL758): Peripheral RIPK1 inhibitor in development for the treatment of ulcerative colitis (UC)

• Sanofi is conducting the ongoing Phase 2 study of SAR443122/DNL758 in participants with UC.
  

Early-stage clinical and preclinical programs

DNL126: ETV-enabled N-sulfoglucosamine sulfohydrolase (SGSH) replacement therapy in development for the treatment of MPS IIIA (Sanfilippo syndrome Type A)

• Denali today announced that preliminary data from up to 25 weeks of dosing in the ongoing open-label Phase 1/2 study in MPS IIIA participants demonstrate a significant reduction in CSF HS levels from baseline, including normalization. The safety profile supports continued development. The most frequent treatment emergent adverse events were infusion related reactions of mild and moderate severity in all participants. There was one serious adverse event considered by the investigator not related to drug. Denali plans to present the data at a future medical meeting.
• Based on the preliminary Phase 1/2 results and a positive regulatory environment, Denali recently expanded the study and continues to assess the development plans including an accelerated approval path.
• DNL126 was selected in June 2024 for the FDA's Support for clinical Trials Advancing Rare disease Therapeutics (START) program to accelerate the development of rare disease therapeutics, and collaborative engagement has commenced to support progress to a pre-BLA meeting.
  

TAK-594/DNL593: Protein Transport Vehicle (PTV)-enabled progranulin (PGRN) replacement therapy in development for the treatment of frontotemporal dementia-granulin (FTD-GRN)

• Screening of participants for Cohort B2 in the Phase 1/2 study is ongoing.
  

Oligonucleotide Transport Vehicle (OTV) platform

• Denali is advancing OTV:MAPT, targeting tau for Alzheimer's disease, and OTV:SNCA, targeting alpha-synuclein for Parkinson's disease, in the investigational new drug (IND)-enabling stage of development.
• In August, announced publication of nonclinical data in the August 14, 2024 issue of Science Translational Medicine (link) demonstrating the ability of the OTV platform to achieve broad biodistribution of antisense oligonucleotides (ASOs) in the central nervous system and skeletal and cardiac muscle following intravenous administration.

Antibody Transport Vehicle Amyloid beta (ATV:Abeta) program

• Denali is working to develop the next generation of anti-amyloid beta therapeutics with ATV:Abeta, which is designed to increase exposure of the therapeutic antibody and achieve broad biodistribution in the brain with the potential for improved efficacy and safety. Preclinical data demonstrated potential for a wider therapeutic window compared to a standard antibody, with superior plaque decoration and reduction and very low rates of amyloid related imaging abnormalities (ARIA). These data are included in a manuscript posted on bioRxiv (link).
• Denali plans to advance a TfR-targeting ATV:Abeta molecule as well as a CD98hc-targeting ATV:Abeta molecule into development for Alzheimer's disease.

Discovery programs

Denali applies its deep scientific expertise in neurodegeneration biology and the BBB to discover and develop medicines and platforms with the focus on programs enabled by the TV technology and targeting neurodegenerative disease, including Alzheimer's and Parkinson's, and lysosomal storage diseases.

2024 Guidance on Operating Expenses

Cash, cash equivalents, and marketable securities were approximately $1.28 billion as of September 30, 2024. Denali is providing updated guidance on cash operating expenses for the full year 2024 and now anticipates an increase of approximately 5-10% compared to 2023, which is an increase from previous guidance of equal to or less than full year 2023 cash operating expenses. This updated guidance is associated with increased activities to support filing of a BLA in early 2025 and commercial readiness for tividenofusp alfa in MPS II, and to accelerate the development of additional therapeutic programs in Denali's TV platform portfolio.

Third Quarter 2024 Financial Results

Net losses were $107.2 million and $99.4 million for the three months ended September 30, 2024 and 2023, respectively.

There was no collaboration revenue for the quarter ended September 30, 2024, compared to $1.3 million for the quarter ended September 30, 2023. The decrease in collaboration revenue was primarily due to activities under the Biogen Collaboration Agreement.

Total research and development expenses were $98.2 million for the quarter ended September 30, 2024, compared to $89.7 million for the quarter ended September 30, 2023. The increase of approximately $8.5 million for the quarter ended September 30, 2024 was primarily attributable to increases in costs in various clinical stage programs, including ETV:IDS, eIF2B, ETV:SGSH, and LRRK2 reflecting the continued progress of these programs in clinical trials, and increases in TV platform and other program external expenses, reflecting continued investment in TV-enabled product candidates. These increases were partially offset by a decrease in personnel and external expenses associated with the divestiture of Denali's preclinical small molecule programs.

General and administrative expenses were $24.9 million for the quarter ended September 30, 2024, and $25.3 million for the same period in 2023.
