[{"type":"text","content":"Denali plans to continue clinical development of DNL593, which is designed to deliver progranulin to the brain using TransportVehicle™ technologyResults from ongoing Phase 1/2 study in patients with FTD-GRN expected by the end of 2026 SOUTH SAN FRANCISCO, Calif., April 03, 2026 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (Nasdaq: DNLI) today announced that it has received notification from Takeda of its decision to terminate the collaboration agreement between the two companies to co-develop and co-commercialize DNL593 (PTV:PGRN). The decision was driven by strategic considerations and is not related to efficacy or safety data. DNL593 is an investigational progranulin replacement therapy utilizing Denali’s Protein TransportVehicle™ (PTV) to deliver progranulin across the blood-brain barrier to the brain for the treatment of frontotemporal dementia-granulin (FTD-GRN). Denali has led development activities and will regain full control of DNL593 and its intellectual property portfolio. “While we have greatly valued our partnership, we are pleased to regain full ownership of DNL593. We remain confident in the scientific rationale and the data generated to date, and we look forward to advancing DNL593 independently. We plan to report results from the ongoing Phase 1/2 trial by the end of 2026,” said Ryan Watts, Ph.D., Chief Executive Officer of Denali Therapeutics. “Our TransportVehicle platform is the first FDA-approved blood-brain barrier-crossing technology, enabling a robust portfolio with broad potential across neurodegenerative diseases like frontotemporal dementia, where there are no currently approved treatment options to slow the progression of this devasting disease.” As previously disclosed, data from the ongoing Phase 1/2 study of DNL593, including biomarker results, are expected by the end of 2026. Enrollment in this study is completed with a total of 40 participants with FTD-GRN. Interim results from Part A of the Phase 1/2 study in healthy volunteers demonstrated dose-dependent increases in cerebrospinal fluid progranulin levels, consistent with robust brain delivery of DNL593. DNL593 was generally well tolerated, and there have been no significant safety signals to date.
