[GlobeNewswire](https://www.globenewswire.com/news-release/2026/10/28/3389900/0/en/nxera-pharma-secures-exclusive-rights-to-fabry-disease-phase-3-oral-therapy-candidate-lucerastat-for-japan-and-selected-asia-pacific-markets.html) reported the co-development and commercialization agreement on October 28, 2026. ## Nxera's Lucerastat Rights and Phase 3 Role [Nxera Pharma](https://akta.pro/company-profiles/000418w/nxera-pharma) will hold exclusive rights to develop and commercialize lucerastat in its territory and will contribute to the global Phase 3 development program. Idorsia is eligible to receive royalties on net sales in the territory. Idorsia granted the option in July 2023 as part of Nxera's acquisition of Idorsia's Asia Pacific operations outside China. Lucerastat is an investigational oral substrate reduction therapy designed to reduce production of Gb3, a fatty substance that builds up in cells and damages the kidneys, heart and nervous system in Fabry disease. In the 118-patient Phase 3 MODIFY study, lucerastat significantly reduced plasma and urinary Gb3 compared with placebo. In an interim analysis of the open-label extension, treatment was associated with a slower rate of kidney function decline compared with the two years before enrollment, with an eGFR slope of -1.64 on lucerastat versus -3.50 historical. Idorsia initiated FAB-KLEAR, a pivotal Phase 3 kidney biopsy study in 16 adult male patients, as part of a global program that also includes a 74-patient study comparing lucerastat with standard-of-care enzyme replacement therapies on kidney function. Nxera will take part in the comparative kidney function study and will manage clinical development in Japan. Christopher Cargill, President and CEO of Nxera Pharma, said: “The clinical evidence generated to date, together with the defined Phase 3 development program, gives us confidence in the potential of lucerastat for people living with Fabry disease.” Amer Joseph, Chief Medical Officer and Head of Global Clinical Development at [Idorsia](https://akta.pro/company-profiles/00009sm/idorsia), said: “While the primary endpoint of neuropathic pain reduction was not met, a subjective outcome that is proving difficult to reach in Fabry disease, lucerastat demonstrated robust and sustained biomarker reductions and a promising signal for slowing renal function decline in patients.” ## Nxera's Recent Partnership Milestones According to akta.pro [company records](https://akta.pro/company-data), Nxera triggered a US$22.5 million milestone from Neurocrine Biosciences in April 2026 as the first patient was dosed in a Phase 2 trial of NBI-1117570 in schizophrenia. In May 2026, Nxera closed a licensing agreement and Series A financing with a newly formed GPCR-focused spin-out, granting worldwide rights outside Asia Pacific while retaining Japan and certain Asia Pacific territories, with up to US$275 million in milestones plus tiered royalties. ## Nxera's Path to the Lucerastat Deal In June 2026, Nxera achieved its fourth R&D milestone under its multi-target discovery collaboration with AbbVie targeting neurological diseases, resulting in a US$10 million payment, GlobeNewswire reported. In August 2026, Nxera reported first half GAAP earnings per share of ¥15.86 and revenue of ¥18.91 billion, a 25.3% year-over-year increase, according to Seeking Alpha. Also in August 2026, partner Neurocrine Biosciences received FDA IND acceptance for a Phase 2 study of NBI-1117567 for Alzheimer's cognition, Yahoo reported. ## Lucerastat Filing Timeline The global Phase 3 program is expected to support a regulatory filing as early as 2029. Nxera will release its third-quarter 2026 earnings and present operational highlights on October 30, 2026, with a results and R&D webinar at 5 p.m. JST, The future of trading reported. ## Companies in this story - [Nxera Pharma company profile](https://akta.pro/company-profiles/000418w/nxera-pharma) · website: https://www.nxera.life - [Idorsia company profile](https://akta.pro/company-profiles/00009sm/idorsia) · website: https://www.idorsia.com --- News for Agent · https://newsforagent.com/llms.txt
