Zydus Lifesciences Limited a leading discovery-based, global pharmaceutical company, announced today that it has received permission from USFDA, to initiate the Phase II clinical study of NLRP3 inhibitor “ZYIL1” in patients with Parkinson’s disease.

Parkinson’s is a devastating disease with patients steadily losing the control on movements leading to unintended or uncontrollable movements, such as shaking, stiffness and difficulty with balance and co-ordination.

It is estimated that there are more than 8.5 million people in the world suffering from Parkinson’s disease, with 1 million suffering from the disease in the US.

Each year 90,000 new cases of Parkinson’s disease are reported in the US.

Analysts estimate that the treatment costs of Parkinson’s disease amounts to almost U.S. $52 billion every year, and by 2037 this disease is estimated to touch U.S. $80 billion every year.

“Our researchers have been working on path-breaking discoveries that can unlock new possibilities and help patients lead more healthier and fulfilled lives. Our team is developing a novel, disease modifying approach through inhibiting the activation of NLRP3 inflammasome with ZYIL1, which could potentially reduce neuroinflammation and neuro-degeneration in patients suffering from Parkinson’s disease.”

Mr. Pankaj R. Patel, Chairman, Zydus Lifesciences Ltd.

ZYIL1

ZYIL1 is a novel oral small molecule NLRP3 inhibitor. Studies have demonstrated that ZYIL1 is highly potent and can suppress inflammation caused by NLRP3 inflammasome activation. ZYIL1 was found distributed in the brain & CSF of various nonclinical species including mice, rats and non-human primates. The efficacy of ZYIL1 has been established in a number of validated pre-clinical models of neuro-inflammation and Parkinson’s disease. ZYIL1, has demonstrated desirable ADME profile, with good safety margin. In phase I studies, ZYIL1 was found to be safe and well-tolerated in human volunteers [NCT04731324, NCT04972188]. The Phase 2 study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics in patients with Parkinson’s Disease.

Previously, Zydus had demonstrated the efficacy of ZYIL1 in CAPS (Cryopyrin Associated Periodic Syndrome) patients [NCT05186051] and was the first to establish the phase 2 proof of concept with an oral small molecule NLRP3 inhibitor in CAPS patients. The phase-2 data of ZYIL1 in CAPS has now been published in “Clinical Pharmacology in Drug Development”. Zydus has been granted an ‘Orphan Drug Designation’ by the US FDA for ZYIL1 in the treatment of patients with CAPS, a rare auto-inflammatory disease.

Additionally, Zydus has also initiated Phase 2 clinical trial of ZYIL1 in patients with Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease [ClinicalTrials.gov Identifier: NCT05981040].
