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

• In May, the Sean M. Healey & AMG Center for ALS at Massachusetts General Hospital (MGH) in collaboration with the Northeast ALS Consortium (NEALS) announced that enrollment is complete in Regimen G (DNL343) of the Phase 2/3 HEALEY ALS Platform Trial.
  

SAR443820/DNL788: CNS-penetrant RIPK1 inhibitor in development for the treatment of multiple sclerosis (MS)

• Sanofi is evaluating SAR443820/DNL788 in a Phase 2 study in participants with MS, which is fully enrolled.
  

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 plans to initiate a global Phase 2a study in 2024 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)

• In June, Denali announced that the CDER selected DNL126 for participation in the FDA's Support for clinical Trials Advancing Rare disease Therapeutics (START) Pilot Program to further accelerate the development of novel drug and biological products for rare diseases. Participation in START is expected to facilitate and accelerate development of DNL126.

• Phase 1/2 biomarker and safety data are expected by the end of 2024.

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

• Denali has finalized the protocol amendment for the Phase 1/2 study and prescreening of participants for Cohort B2 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.
  

Antibody Transport Vehicle Amyloid beta (ATV:Abeta) program

• Today, Denali also announced that Biogen terminated its license to the ATV:Abeta program enabled by Denali’s TfR-targeting technology against amyloid beta for the potential treatment of Alzheimer's disease and granted Denali rights to data generated during the collaboration. As a result of the termination, all rights to develop, manufacture, perform medical affairs activities, and commercialize new TfR-targeting ATV:Abeta therapeutics reverted to Denali. Biogen licensed Denali's TfR-targeting ATV:Abeta program in April 2023 having exercised an option that was part of the 2020 collaboration agreement between the two companies. Biogen’s decision was not related to any efficacy or safety concerns with the Transport Vehicle platform.

• 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 recent manuscript posted on bioRxiv.

• 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.

• In July, Denali posted the manuscript titled, "Fc-engineered large molecules targeting the blood-brain barrier transferrin receptor and CD98hc have distinct central nervous system and peripheral biodistribution compared to standard antibodies" on bioRxiv. Using comprehensive and unbiased approaches, Denali scientists reveal distinct biodistribution of the TfR and CD98hc transport vehicle delivery platforms from the brain single-cell level all the way to the whole body.

Second Quarter 2024 Financial Results

Net loss was $99.0 million for the quarter ended June 30, 2024, compared to net income of $183.4 million for the quarter ended June 30, 2023.

There was no collaboration revenue for the quarter ended June 30, 2024, compared to $294.1 million for the quarter ended June 30, 2023. The decrease in collaboration revenue was primarily due to $293.9 million of revenue recognized in the quarter ended June 30, 2023 as a result of Biogen exercising their option to license our ATV:Abeta program.

Total research and development expenses were $91.4 million for the quarter ended June 30, 2024, compared to $97.5 million for the quarter ended June 30, 2023. The decrease of approximately $6.1 million for the quarter ended June 30, 2024 was primarily attributable to a decrease in personnel and external expenses associated with the divestiture of the Company's preclinical small molecule programs. There were also decreases in external expenses associated with the ATV:TREM2 and PTV:PGRN programs due to the discontinuation of clinical development of TAK-920/DNL919 (ATV:TREM2) in Alzheimer’s disease and voluntary pause of Part B in the TAK-594/DNL593 (PTV:PGRN) Phase 1/2 study, respectively. Additionally, the Company commenced recognition of research funding for the LRRK2 program from the Collaboration and Development Funding Agreement executed in January 2024. These decreases were partially offset by increases in costs in various clinical stage programs, including eIF2B, ETV:SGSH and ETV:IDS reflecting the continued progress of these programs in clinical trials.

General and administrative expenses were $25.2 million for the quarter ended June 30, 2024, compared to $26.1 million for the quarter ended June 30, 2023. The decrease of $0.9 million for the quarter ended June 30, 2024 was primarily attributable to a decrease in personnel-related expenses consisting of employee compensation and stock-based compensation expense, partially offset by combined increases of $0.2 million in professional services, facilities and other corporate costs.

Cash, cash equivalents, and marketable securities were approximately $1.35 billion as of June 30, 2024.
