NOVATO, Calif., Oct. 03, 2024 (GLOBE NEWSWIRE) -- Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) today reported that the Phase 1/2/3 Cyprus 2+ study of its UX701 gene therapy has demonstrated meaningful clinical activity as well as improvements in copper metabolism in Stage 1. Multiple responders have completely tapered off of standard-of-care treatment with responses seen in all three dose cohorts. The company plans to enroll an additional cohort in Stage 1 at a moderately increased dose and with an optimized immunomodulation regimen to enhance the efficiency and efficacy of the gene therapy, with the objective of having the majority of patients come off of standard-of-care treatment before selecting a dose for the randomized placebo-controlled stage of the study. In Stage 1, 15 patients were enrolled into three sequential dosing cohorts and followed for at least 24 weeks. Six of the patients have completely tapered off of standard-of-care treatment with chelators and/or zinc therapy, and a seventh patient has begun to taper as of the data cut-off date in August. In patients who have tapered off standard-of-care, non-ceruloplasmin bound copper (NCC) has stabilized to normal, healthy levels. In some patients, there were increases in ceruloplasmin-copper activity consistent with improved ATP7b function. From a safety perspective, UX701 has been well tolerated, with no unexpected related treatment emergent adverse events and no significant immunologic safety events as of the data cut-off. The company will be submitting a protocol amendment for the additional cohort at a moderately increased dose and with an optimized immunomodulation regimen to optimize delivery efficiency and efficacy for the AAV vector. “We are encouraged by the clinical activity we’re seeing with UX701 at this interim timepoint, with clear signals of transgene expression and improved trafficking of copper in a subset of patients currently enrolled in the study. These results, in addition to a number of patients tapering off of standard-of-care, give us confidence that this could ultimately be a novel therapy for people living with Wilson disease,” said Eric Crombez, M.D., chief medical officer at Ultragenyx. “A higher dose and optimized immunomodulation should enhance the clinical effect of this gene therapy and the ability to remove current standard-of-care in an even broader set of patients.” U.S. residents can learn more by visiting . Phase 1/2/3 Cyprus 2+ Study Design This study evaluating UX701 for the potential treatment of Wilson disease is designed with three stages. During the first stage (Stage 1), the safety and efficacy of multiple dose levels of UX701 will be evaluated and a dose will be selected for further evaluation in Stage 2. To date, 15 patients have been enrolled into three sequential dosing cohorts to evaluate doses of 5.0 x 10^12 GC/kg, 1.0 x 10^13 GC/kg, and 2.0 x 10^13 GC/kg. A fourth dosing cohort will be added and all patients in Stage 1 will be evaluated over the course of 52 weeks. In Stage 2, a new cohort of patients will be randomized 2:1 to receive the selected dose of UX701 or placebo. The primary safety and efficacy analyses will be conducted at Week 52 of Stage 2. The primary efficacy endpoints are change in 24-hour urinary copper concentration and percent reduction in standard-of-care medication by Week 52. After the initial 52-week study period, all patients will have long-term follow up in Stage 3. About Wilson Disease Wilson disease is a rare inherited disorder caused by mutations in the ATP7B gene, which results in deficient production of ATP7B, a protein that transports copper. Loss of function of this copper-binding protein results in the accumulation of copper in the liver and other tissues, most notably the central nervous system, and failure to properly distribute copper by ceruloplasmin. Patients with Wilson disease experience hepatic, neurologic and/or psychiatric problems. Those with liver disease can experience such symptoms as fatigue, lack of appetite, abdominal pain and jaundice, and can progress to fibrosis, cirrhosis, life-threatening liver failure and death. Wilson disease can be treated by reducing copper absorption or removing excess copper from the body using life-long chelation therapy, but unmet needs exist because some treated patients experience clinical deterioration and severe side effects. Wilson disease affects more than 50,000 people in commercially accessible geographies. About UX701 UX701 is an investigational AAV9 gene therapy designed to deliver stable expression of the ATP7B copper transporter following a single intravenous infusion. It has been shown in preclinical studies to normalize copper trafficking and excretion from the body. UX701 has been granted Orphan Drug Designation in the United States and European Union and Fast Track Designation in the United States. About Ultragenyx Pharmaceutical Inc.

VTX-801 increased ceruloplasmin ferroxidase activity and improved liver histology Encouraging safety and tolerability with no serious adverse events reported PARIS, June 5, 2024 /PRNewswire/ -- Vivet Therapeutics ("Vivet"), a clinical stage biotech company developing novel and long-lasting gene therapies for rare inherited liver metabolic disorders, today announces the presentation of interim data on its international Phase 1/2 GATEWAY trial, evaluating the safety, pharmacodynamics, and efficacy of its lead program, VTX-801 for the treatment of Wilson Disease (WD) at the EASL Congress 2024, held in Milan, Italy. The poster presentation by Ass. Professor, Thomas Damgaard Sandahl entitled ' Interim safety results of the ongoing international phase I/II GATEWAY gene therapy trial with VTX-801 conducted in adult patients with Wilson Disease', detailed findings from Cohort 1 patients in the ongoing GATEWAY trial treated with Vivet's lead program, VTX-801, a recombinant adeno-associated viral vector (rAAV) carrying a shortened ATP7B gene under the control of a liver-specific promoter for the treatment of Wilson Disease. GATEWAY is a first-in-human, open label, 5-year follow-up, single dose escalation study being conducted to assess the safety, pharmacodynamics, and efficacy of VTX-801, with the objective of providing long lasting effects after a single intravenous administration in patients living with WD. Following evaluation, standard of care treatment may be withdrawn at 3- or 9-months post-infusion in VTX-801 responders; the response is defined based upon intravenously injected 64Cu PK profiles, which is considered to reflect the level of restoration of copper metabolism. Data presented at EASL is outlined below for the two Cohort 1 patients who received a single intravenous injection of VTX-801: Encouraging safety and tolerability, with no serious adverse events reported; an infusion associated reaction was managed with symptomatic treatment, patient discharged the next day as planned; transient, mild liver enzymes elevations occurred and managed in line with other systemic AAV gene therapies Increases from baseline of ceruloplasmin ferroxidase activity observed, demonstrating transgene activity in both patients treated Liver biopsy results showing normalisation of liver fibrosis and iron accumulation scores at year 1 post treatment Jean-Philippe Combal, Co-Founder & Chief Executive Officer at Vivet Therapeutics, said "Existing life-long oral treatments for WD are constraining and associated with side effects, leading to poor adherence and in some cases, severe WD complications. These interim data presented at EASL are encouraging for the development of an alternative treatment option for WD, following completion of Cohort 1, which demonstrated promising safety, tolerability and early pharmacodynamic changes. In Cohort 2, we have dosed the first patient with VTX-801 at an escalated dose level and we hope for a more robust pharmacodynamic response at a much higher magnitude. We are pleased so far with the progress of the study and continue with the perspective of developing VTX-801 as a potential disease-modifying treatment for people living with WD." Further details on the GATEWAY trial can be found on Clinical Trials, under identifier NCT04537377. Study authors: T. D. SANDAHL1, W. M. LEE2, A. ALA 3, R. P. GONZALEZ-PERALTA 4, V. MEDICI 5, F. K.
