Zydus Lifesciences gets positive Proof-of-Concept in Phase 2 clinical study of ‘ZYIL1’

08 Sep 2022 Evaluate

Zydus Lifesciences has achieved positive Proof-of-Concept in its Phase 2 clinical study of ZYIL1, in patients with CAPS. CAPS is a rare, life-long, auto-inflammatory condition, caused by NLRP3 activating mutations and is classified as an orphan disease. The chronic inflammation due to IL-1beta release in CAPS patients leads to urticaria-like rash, fever, arthralgia, and increased risk of amyloidosis. CAPS patients also experience multiple neurological complications like sensorineural hearing loss, migraine, headache, aseptic meningitis and myalgia. Bone deformities and neurological impairments have been reported in Neonatal Onset Multisystem Inflammatory Disease (NOMID), the most severe form of CAPS.

The Phase 2 trial conducted in Australia, evaluated the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of ZYIL1 in Subjects with Cryopyrin Associated Periodic Syndromes (CAPS). ZYIL1 showed rapid oral absorption. ZYIL1 is extremely potent (IC50 in nanomolar range) in human whole blood and supressed inflammation caused by the NLRP3 inflammasome. Robust effect on disease biomarkers including CRP, Serum Amyloid A (SAA), IL-6, WBC, was also observed.

ZYIL1 was safe and well-tolerated and there were no Serious Adverse Events (SAE’s) observed in this Phase 2 trial. Liver and kidney function tests also did not show any abnormalities in this Phase 2 trial. CAPS patients with confirmed NLRP3 mutation suffering from CAPS-related flare up, when treated with ZYIL1 in Phase 2 Proof-of-Concept trial showed rapid clinical improvement as early as day 3 which sustained till the end of treatment.
