• Results of PXL065 Phase 2 (DESTINY-1) trial in NASH expected in Q3 2022

LYON, France–(BUSINESS WIRE)–POXEL SA (Euronext: POXEL – FR0012432516), a clinical stage biopharmaceutical company developing innovative treatments for serious chronic diseases with metabolic pathophysiology, including non-alcoholic steatohepatitis (NASH) and rare metabolic disorders, announced today that the U.S. Patent and Trademark Office (PTO) has issued to Poxel US Patent No. 11319313 which represents a new patent for PXL065, a novel, proprietary deuterium-stabilized R-stereoisomer of pioglitazone. The new patent describes a specific form of PXL065 with unique properties. Importantly, this recently issued patent provides additional protection through 2041 and could expand protection for PXL065 worldwide, with the potential for an additional 5 years through patent term extension.

Poxel CEO, Thomas Kuhn, commented: “We are pleased that our continuing efforts to enhance our patent portfolio has resulted in this successful addition of a key patent to our intellectual property. This new patent for PXL065 extends exclusivity, and we are also prosecuting the related patent applications globally. We also look forward to reporting Phase 2 DESTINY-1 topline results for PXL065 in NASH expected in the third quarter.”

Acquired in 2018, pursuant to a strategic agreement with DeuteRx, PXL065 is the deuterated-stabilized R stereoisomer (single R-isomer) of pioglitazone, its parent molecule. It is currently being evaluated in a Phase 2 study (DESTINY-1) for NASH, with results expected in Q3 2022, and will be evaluated in a Phase 2a biomarker proof-of-concept (POC) clinical trial for adrenoleukodystrophy (ALD), which is prepared to initiate as soon as possible, subject to additional financing.
