Zydus Lifesciences Completes Phase II(a) Trial of Usnoflast for ALS

Ahmedabad, India, 11 September, 2024

Zydus, a leading discovery-based, global pharmaceutical company, announced the completion of its Phase II(a) clinical study of NLRP3 inhibitor ‘Usnoflast (ZYIL1)’ in patients with Amyotrophic Lateral Sclerosis (ALS).

ALS patients experience neuroinflammation and rapid neurodegeneration. Axonal neurodegeneration leads to formation of neurofilaments which first accumulate in CSF of ALS patients, and then slowly these neurofilaments enter blood circulation. Owing to rapid neurodegeneration, steady loss of the ability to move, speak, eat, eventually breathe, paralysis and death have been reported in ALS patients.

ALS affects approximately 32,000 people in the U.S.A and on an average 5,000 new patients are diagnosed every year with this disease in USA as per statistics from Centers for Disease Control and Prevention (CDC). More than 30,000 people are estimated to be living with ALS in Europe (European Union and United Kingdom), while India has an estimated 75,000 people living with ALS. People living with ALS have an average survival of approximately two to five years from diagnosis, with most ALS patients dying from respiratory failure.

Speaking on the development, Mr. Pankaj Patel, Chairman, Zydus Lifesciences Limited said “This is a first-in-class innovation and represents a significant scientific breakthrough in our quest for finding new medicines for treating ALS patients. We are excited to report that Usnoflast has been able to reach therapeutic concentrations in CSF of ALS patients and reduce the neurofilaments in CSF in this initial Phase 2(a) study. Clinicians have reported improvements in ALSFRS-R score. The improvement observed in SVC (Slow Vital Capacity) in ALS patients has been encouraging in this 12-week trial. We now look forward to conducting a larger Phase 2b clinical trial in consultation with the regulatory authorities.”

The Phase 2(a) randomized, double-blind, placebo controlled clinical trial recruited 24 ALS patients across 7 clinical trial sites in India and evaluated the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Usnoflast in Subjects with ALS [ClinicalTrials.gov Identifier: NCT05981040]. Zydus will publish the detailed clinical trial results in leading medical journals and upcoming scientific conferences.

Usnoflast (ZYIL1) is a novel, oral small molecule NLRP3 inhibitor. Studies have demonstrated that Usnoflast is highly potent in human whole blood assay and can suppress inflammation caused by the NLRP3 inflammasome. Usnoflast was found distributed in the brain and CSF of various nonclinical species including mice, rats and non-human primates. The efficacy of Usnoflast has been established in several pre-clinical models of neuroinflammation, Parkinson’s disease8, Inflammatory Bowel Disease (IBD) and Multiple Sclerosis (MS). Usnoflast, has an acceptable Absorption, Distribution, Metabolism, Excretion (ADME) profile, with a good safety margin. In Phase I studies, Usnoflast was found to be safe and well-tolerated. Zydus has established the Phase 2 proof-of-concept in CAPS patients [NCT05186051] and had earlier published the data in journal ‘Clinical Pharmacology in Drug Development’. The USFDA has granted Zydus an ‘Orphan Drug Designation’ for Usnoflast to treat patients with Cryopyrin Associated Periodic Syndrome (CAPS), a rare auto-inflammatory disease. Zydus has initiated a Phase 2 clinical study of Usnoflast in Ulcerative Colitis
