Drug Farm Announces First Patients Dosed in Phase 1b Clinical Trial Evaluating ALPK1 Inhibitor, DF-003 in ROSAH Syndrome
DF-003 is a first-in-class, immune-modulating alpha-kinase 1 (ALPK1) inhibitor that targets ALPK1 mutants causing ROSAH syndrome. The trial is evaluating the safety, pharmacokinetics and efficacy of orally administered DF-003 at sites in the USA and Australia.
'We are happy to offer patients with ROSAH syndrome the opportunity to participate in a clinical trial using a new precision-targeted drug to treat the root cause of their disease,' said Dr. John Grigg, Professor of Clinical and Experimental Ophthalmology, Save Sight Institute Faculty of Medicine and Health at The University of Sydney.
'The initiation of this trial is a critical step forward in our goal to provide a therapeutic option in disease indications with unmet medical need that are mediated by excessive ALPK1 activation,' said Henri Lichenstein, PhD, Chief Executive Officer of Drug Farm. 'We are optimistic about the potential of DF-003 to make a meaningful difference in the lives of patients with ROSAH, and together with our collaborators, are committed to thoroughly investigating the safety and efficacy of DF-003 in patients with atherosclerotic cardiovascular disease as well.'
About DF-003
DF-003 is a proprietary, first-in-class drug developed by Drug Farm that inhibits the activity of ALPK1 and variants of ALPK1 which cause ROSAH syndrome. DF-003 has therapeutic potential for ROSAH syndrome, as well as heart and kidney diseases, as the drug has shown efficacy in preclinical models of these indications. DF-003 has completed a Phase 1 clinical trial (NCT05997641) in normal healthy volunteers and is now accruing patients with ROSAH syndrome in a Phase 1b trial (NCT06395285).
About ROSAH Syndrome
ROSAH (retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis and headache) syndrome is a rare, autosomal dominant autoinflammatory genetic disease named according to the characteristic symptoms exhibited by affected patients (1, 2). Disease-causing mutations in ALPK1 lead to ROSAH syndrome. The most common presenting symptom is a progressive decline in visual acuity that typically begins before 20 years of age, with ophthalmologic examination often revealing optic disc elevation, uveitis, and retinal nerve degeneration (2, 3). Most ROSAH patients also exhibit inflammatory features such as non-infectious low-grade fevers, arthralgia, headaches, and persistently elevated levels of inflammatory cytokines including tumor necrosis factor-α (TNFα), interleukin-6 (IL-6), and IL-1β (3).

Experts from Witherite Law Group say Autonomous Trucks are Not Ready for Texas Roads
DALLAS--(BUSINESS WIRE)--Attorney and truck safety advocate Amy Witherite warns that autonomous trucks still face serious safety gaps—acknowledged by their own developers, confirmed by independent studies, and underscored by industry experts. Waabi CEO Raquel Urtasun has called her company's simulator-based approach 'provably safe,' saying real-world testing in the millions of miles 'is nowhere near what would be required to provide the rigorous evidence necessary for a comprehensive safety case.' Professor Philip Koopman of Carnegie Mellon University, one of the world's leading autonomous vehicle safety researchers, cautions that true safety requires ultra-reliability: 'Safety isn't about working right most of the time. Safety is all about the rare case where it doesn't work properly. It has to work 99.999999999% of the time. AV companies are still working on the first few nines, with a bunch more nines to go.' Witherite says those two statements highlight the gap between marketing promises and operational reality: 'Even the most advanced companies admit they're far from testing at the scale needed to prove safety under real-world conditions. Experts are telling us this technology is still working out the basics—so putting it on Texas highways is reckless.' This comes as Aurora Innovation begins nighttime runs of its self-driving trucks on the Dallas–Houston route—still with a human observer in the cab 'though no manual intervention is required'—and Texas A&M Transportation Institute warns that AI-driven systems remain limited by their programming, sensor range, and narrowly defined operational design domains. Meanwhile, FMCSA's 2023 Pocket Guide to Large Truck and Bus Statistics shows Texas is not only the deadliest state for large truck crashes in raw numbers—with 821 fatalities in 2021—but also has a per-mile fatality rate of 0.29 per 100 million vehicle miles traveled, well above the U.S. average of 0.19. While a few states have even higher per-mile rates, Texas still ranks in the higher-risk tier nationally and far exceeds states like California despite having a smaller population. In 2023 alone, Texas recorded 650 deadly large-truck crashes—52% more than California, the next highest state. 'Texas can't afford to be the test track for unproven technology,' Witherite said. 'We already have the highest truck crash fatality numbers in the country and a safety rate worse than the national average. Until autonomous trucks can meet the extreme reliability experts demand, they have no place in live traffic.' Amy Witherite is the founding attorney of Witherite Law Group and a nationally recognized traffic safety advocate. She has represented hundreds of families affected by trucking collisions.
