SOUTH SAN FRANCISCO, Calif., Sept. 29, 2021 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (NASDAQ: DNLI), a biopharmaceutical company developing a broad portfolio of product candidates engineered to cross the blood-brain barrier (BBB) for neurodegenerative diseases, today announced upcoming presentations at the 2021 Annual Northeast Amyotrophic Lateral Sclerosis (NEALS) Meeting being held virtually, October 6-7.

Denali will present preclinical and clinical data including results from a Phase 1 healthy volunteer study of its CNS-penetrant EIF2B activator DNL343, which is currently under investigation in a Phase 1b study in participants with ALS. Denali’s partner Sanofi will present plans for a Phase 2 study in participants with ALS, with the CNS-penetrant RIPK1 inhibitor SAR443820, which completed investigation in a Phase 1 study in healthy volunteers.

About DNL343

Modulation of EIF2B activity with DNL343 is a novel and targeted investigational approach with first-in-class potential for the treatment of ALS. EIF2B is an intracellular protein complex that regulates protein synthesis and is required for neuronal health and function. When neurons experience stress, as occurs in ALS, EIF2B activity is suppressed. This leads to impaired protein synthesis and results in the formation of "stress granules," which are thought to be a precursor of TDP-43 aggregation, a hallmark pathology in ALS. DNL343 is designed to activate EIF2B and thereby restore protein synthesis, disperse TDP-43 aggregates, and improve neuronal survival.

Denali is conducting a multicenter, randomized, placebo-controlled, double-blind, 28-day study followed by an 18-month open-label extension, designed to evaluate the safety, pharmacokinetics, and pharmacodynamics of DNL343 in participants with ALS. Further information on the Phase 1b study (study number NCT05006352) can be accessed on the ClinicalTrials.gov website or by clicking here.

About SAR443820/DNL788

SAR443820/DNL788 is a novel, CNS-penetrant, small molecule inhibitor of RIPK1, a critical signaling mediator of necroptotic cell death, cytokine release, and inflammatory pathways. Denali and Sanofi entered into a broad collaboration in October 2018 for the global development and commercialization of RIPK1 inhibitors. This includes CNS-penetrant molecules such as SAR443820/DNL788, which was evaluated in a Phase 1 study in healthy volunteers, with potential development for neurological indications such as ALS, multiple sclerosis (MS) and Alzheimer’s disease (AD).

Denali Webinar for Analysts and Investors on October 6, 2021

Denali plans to host a webinar for analysts and investors to highlight development programs in ALS and frontotemporal dementia (FTD) on October 6, starting at approximately 4:30 p.m. Eastern Time. During the webinar, Denali will review the NEALS presentations related to its investigational small molecule therapeutics DNL343 and SAR443820. Denali will also review preclinical data on PTV:PGRN, its Transport Vehicle (TV)-enabled biotherapeutic in development for FTD-GRN, which was recently published in Cell. The webinar will be available on Denali’s corporate website on the Events page under the Investor section at https://www.denalitherapeutics.com/investors/events. An archived replay of the webinar will be available for at least 30 days following the event. Preregistration for the webinar can be accessed here.
