LRRK2 inhibitor(Interline Therapeutics)

SOUTH SAN FRANCISCO, Calif., Dec. 05, 2024 (GLOBE NEWSWIRE) -- Denali Therapeutics Inc. (Nasdaq: DNLI) today announced initiation of dosing in a global Phase 2a clinical study, BEACON, of the investigational drug leucine-rich repeat kinase 2 (LRRK2) inhibitor BIIB122 (DNL151) in participants with LRRK2-associated Parkinson’s disease (LRRK2-PD). LRRK2 inhibition is a potential therapeutic approach that may slow progression of Parkinson’s disease by targeting underlying lysosomal dysfunction implicated in this disease. The Phase 2a study is intended to evaluate safety and biomarkers associated with oral daily dosing of BIIB122 in approximately 50 participants with Parkinson’s disease and LRRK2 pathogenic mutations confirmed by genetic testing. The study is designed to enroll participants into a double-blind treatment period of three months followed by an open label extension. Denali holds the Investigational New Drug application for this Phase 2a study and is leading its design and execution. This study is being funded under a Collaboration and Development Funding Agreement between Denali and a third party. BIIB122 is also being investigated in the ongoing global Phase 2b LUMA study in participants with early-stage Parkinson’s disease with or without a LRRK2 mutation, in collaboration with Biogen. “We are thrilled to initiate this study and broaden our efforts in evaluating BIIB122 as a potential treatment for people living with Parkinson’s disease related to LRRK2 mutations,” said Carole Ho, M.D., Chief Medical Officer at Denali. “We look forward to continued collaboration with the Parkinson’s community as we aim to generate biomarker and safety data to inform how LRRK2 inhibition may have an impact on the course of this disease.” “LRRK2 continues to be a prominent target in Parkinson’s research, and a priority area of focus for disease-modifying therapies,” said Todd Sherer, Ph.D., Chief Mission Officer of The Michael J. Fox Foundation. “The Phase 2a study of BIIB122 is a meaningful milestone in advancing the potential of LRRK2 as a therapeutic approach for people with Parkinson’s disease.” About LRRK2 and BIIB122 (DNL151)Following discovery of the LRRK2 mutation as a pathogenic genetic factor for Parkinson’s disease, further research has uncovered that it has the potential to be a novel therapeutic target for Parkinson’s disease. Pathogenic mutations in LRRK2 account for 4-5% of familial and 1-2% of sporadic Parkinson’s disease.1,2 BIIB122 (DNL151) is a selective, central nervous system-penetrant small molecule inhibitor of LRRK2 that is hypothesized to improve lysosomal dysfunction. Denali’s strategic partner Biogen is conducting the global Phase 2b LUMA study of BIIB122, which is expected to enroll approximately 640 participants with early-stage Parkinson’s disease, including eligible participants with LRRK2 mutations. More information about the Phase 2b LUMA study (NCT05348785) can be found here. The Phase 2a BEACON study is a multicenter, randomized, 12-week double-blind, placebo-controlled, parallel-group study, followed by an open label extension in participants with LRRK2-PD, which is defined as Parkinson's disease in individuals who are heterozygous or homozygous carriers of a pathogenic LRRK2 variant that increases LRRK2 kinase activity. This study’s purpose is to evaluate the safety, tolerability, and pharmacodynamic effects of BIIB122. More information about the Phase 2a BEACON study (NCT06602193) can be found here. BIIB122 is an investigational drug that is not approved by any regulatory authority, and its safety and efficacy have not been established.

LEHI, Utah I October 7, 2024 I Halia Therapeutics, a clinical-stage biopharmaceutical company at the forefront of developing innovative treatments for inflammatory and neurodegenerative diseases, today announced that the first healthy volunteer was dosed in its Phase 1 clinical trial evaluating its LRRK2 inhibitor, HT-4253, for a potential treatment for Alzheimer’s Disease. “Dosing the first subject in the Phase 1 trial of HT-4253 marks a significant step in the fight against neurodegenerative diseases such as Alzheimer’s disease,” said Dr. David Bearss , CEO of Halia Therapeutics. “We believe that HT-4253 will provide a groundbreaking treatment option for patients who currently have few choices to prevent or delay Alzheimer’s onset, as the drug targets the underlying neuroinflammation linked to causing neurocognitive disease.” The Phase 1 clinical trial ( ClinicalTrials.gov ID: NCT06537817 ) is a first-in-human, randomized, placebo-controlled, double-blind study evaluating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of HT-4253. This study will employ a single ascending dose (SAD) and multiple ascending dose (MAD) format, designed to explore the potential of HT-4253 to inhibit LRRK2—a critical enzyme designed to explore the potential of HT-4253 to inhibit LRRK2. Recent human genetic studies have revealed specific variants of the Rab10 gene protect individuals with the APOE4 genotype—a known risk factor for Alzheimer’s disease. These variants inhibit Rab10, a key protein activated by LRRK2, thus reducing neuroinflammation and offering neuroprotection. Halia’s LRRK2 inhibitor, HT-4253, mimics these Rab10 variants by blocking LRRK2, which in turn prevents Rab10 activation. This mechanism shows promise for preventing or delaying Alzheimer’s onset in APOE4 carriers by replicating the protective effects observed in resilient individuals. About HT-4253 HT-4253 is an orally administered small molecule tablet with excellent brain penetration. It targets LRRK2, a key mediator of neuroinflammation. Chronic brain inflammation drives several neurodegenerative diseases, including Parkinson’s and Alzheimer’s. Halia scientists have demonstrated that LRRK2 is crucial in regulating neuroinflammation. By inhibiting LRRK2, HT-4253 could offer a novel approach to treating neurodegenerative diseases with an inflammatory component, potentially altering disease progression. About Halia Therapeutics, Inc. Halia Therapeutics is pioneering novel therapeutics to enhance patients’ lives affected by chronic inflammatory disorders and neurodegenerative diseases. Our initial programs focus on NEK7 and LRRK2 targets. Our lead candidate, HT-6184—a novel NEK7/NLRP3 inhibitor—has successfully completed a Phase I study ( NCT05447546 ). This study evaluated HT-6184’s safety and tolerability when administered as single or multiple oral doses at escalating levels in healthy volunteers. Additionally, we’ve completed a Phase II trial assessing HT-6184’s efficacy on post-procedure diagnostic biomarkers of inflammation and pain ( NCT06241742 ). Currently, we’re conducting a Phase II trial to investigate HT-6184’s efficacy in treating lower-risk myelodysplastic syndromes (LR-MDS).
